Bulletin Purpose
This is a special bulletin to introduce the 2016 Buick
Cascada. The purpose of this bulletin is to help the
Service Department Personnel become familiar with
some of the vehicle’s new features and to describe
some of the action they will need to take to service this
vehicle.
About the Car
The 2016 Buick Cascada will be the first Buick
convertible offered in North America in 25 years and will
be offered in two trim levels, the Cascada 1SV and the
Cascada Premium 1SP. The Cascada’s 2+2
configuration offers comfortable room for four adults
and Buick’s sophisticated HiPer Strut front suspension
and the responsive Watts Z-link rear suspension,
rooted in a rigid body structure provides an impressive,

comfortable and refined driving experience. The
Cascada rides on a 106.1-inch (2,695 mm) wheelbase
which enhances ride smoothness while enabling
greater rear-seat legroom.
The vehicle is powered by a 1.6L turbocharged engine
that is exclusive to the Cascada in the Buick lineup,
with an estimated 200 horsepower (149 kW) @
5,500 rpm and 207 lb-ft (280 Nm) of torque @ 1,800 to
4,500 rpm with an overboost feature that briefly pushes
torque to an estimated 221 lb-ft (300 Nm) @ 2,200 to
4,000 rpm. Direct injection and variable valve timing
complement the turbocharged engine’s performance
with efficiency and power is transmitted to the ground
via a Hydra-Matic™ 6T45 6-speed FWD automatic
transmission.
The Cascada’s strategically reinforced body structure is
the foundation for the car’s strength and as a result of
the structure’s rigidity, engineers were able to tune the
suspension and steering systems with a high degree of
precision because there wasn’t a need to compensate
for chassis flex. Important elements include:
• A-pillars featuring press-hardened steel in the
inner structures and reinforced with high-strength,
hot-rolled and cold-bent tubes within the pillars.
• Reinforced rocker panels with increased cross
section.
• Underbody reinforcements including X-braces,
V-braces and additional brackets.
• A reinforced torsion box bulkhead behind the
rear seats incorporates the Rollover Protection
System, which includes a reinforced windscreen
frame and spring-loaded, pyrotechnically
activated, pop-up rollover bars. When deployed,
the rollover bars will extend approximately
14-inches (356 mm) to match the height of the
windshield.
4355185
An additional advantage of the Rollover Protection
System is that it enables a rear seat cargo
pass-through from the trunk to the passenger
compartment of 22.4-inch by 12.6-inch (569 mm by
320 mm), because the system is less obtrusive than
Bulletin No.: 16-NA-023
some other vehicle’s hoop-style pop-up protection
systems. When the 50/50-split rear seats are folded the rear seatbacks fold down electronically, longer
items such as skis and wakeboards can be stowed
inside. The Cascada offers plenty of storage space,
including 13.4 cubic feet (380 liters) of cargo room with
the convertible top up and 9.8 cubic feet (280 liters) with
the top down.
4355215
The stowage compartment lid extends rearward to
accommodate the folding softtop. The electro-hydraulic
power roof system features multilayer construction,
including acoustic and thermal barriers. The traditional
convertible fabric roof top with a fleece lining has
superior acoustic and thermal insulation qualities and
can be lowered in only 17 seconds at speeds of up to
31 mph (50 km/h). Up-down operation of the top is
controlled using only one lever. The rigid body
structure allows the top, its folding mechanism and the
Rollover Protection System roll bar apparatus to be
stowed below the car’s belt line and under a hard
tonneau cover for a smooth uninterrupted profile, giving
the car a pure open-air aesthetic with enhanced cargo
space.

dexos® Engine Oil
Page 7
Engine Oil Life System
The vehicle features GM’s engine oil life system, which
better protects engines by recommending oil changes
based on a computer software algorithm using actual
engine operating conditions and can save the vehicle
owner money by avoiding unnecessary oil changes.
Transmission
Hydra-Matic™ 6T45 6-Speed Automatic FWD
Transmission — RPO MH7
3512027
4372460

Ask for and use engine oils that meet the dexos®
specification. Engine oils that have been approved by
GM as meeting the dexos® specification are marked
with either of the dexos1® approved logos that are
shown. For additional information, visit this General
Motors website: http://www.gmdexos.com
Viscosity Grade
Use ACDelco dexos1® synthetic blend SAE 5W-30
viscosity grade engine oil. In an area of extreme cold,
where the temperature falls below −20°F (−29°C) use
SAE 0W-30 engine oil. An oil of this viscosity grade will
provide easier cold starting for the engine at extremely
low temperatures.
Typical view of the Hydra-Matic™ 6T45 6-speed
automatic FWD transmission.
The Hydra-Matic™ 6T45 6-speed front-wheel-drive,
electronically controlled, fully automatic overdrive
transaxle with an electronically controlled torque
converter clutch, comes standard with the 1.6L
turbocharged engine. It consists primarily of a 3
element torque converter, a compound planetary gear
set, friction and mechanical clutch assemblies and a
hydraulic pressurization and control system.
Six-speed automatic transmissions are integral in GM's
initiative to offer vehicles with excellent fuel economy
and driveability. Designed for FWD and AWD
applications, they are used in many of GM's newest
and most popular models. The 6T40 (MH8) and 6T45
(MH7, MHC) share many components. The 6T45 is
rated for greater torque capacity due to specific
component enhancements over the 6T40. Each is part
of GM's family of technologically advanced, fuel-saving
six-speed automatics. The transmission case material
is made from die cast aluminum. The transmission uses
DEXRON® VI transmission fluid.
Torque Converter
The 3-element torque converter contains a pump, stator
and turbine with an integral isolator and clutch. The
torque converter acts as a fluid coupling to smoothly
transmit power from the engine to the transmission. It
also hydraulically provides additional torque
multiplication when required. The clutch pressure plate
Page 8

when applied, provides a mechanical direct drive
coupling of the engine to the transmission. The torque
converter features:
– A single-plate lock-up clutch
– Electronic Controlled Capacity Clutch (ECCC)
technology
– Elliptical cross-section shape
Transmission Gear Ratios
The transmission has the following gear ratios:
• First: 4.58
• Second: 2.96
• Third: 1.91
• Fourth: 1.44
• Fifth: 1.00
• Sixth: 0.74
• Reverse: 2.94
• Final Drive Ratio: 3.23
Transmission Fluid Level and Condition Check
When performing fluid checks, always refer to SI for the
proper procedure.
– The compact transmission design of the
Hydra-Matic™ 6T45 makes proper transmission fluid
level even more critical.
– The transmission fluid level must be checked when
the transmission fluid temperature (TFT) is between
185–203°F (85–95°C).
– The engine must be running when the transmission
fluid oil level check plug is removed.
– Do not add more than 0.5 pint (227 ml) at a time
without rechecking the fluid level.

reduction does not reduce drive wheel slip, the
EBCM will actively apply the brakes on the
slipping drive wheel. During traction control
braking, hydraulic pressure in each drive wheel
circuit is controlled to prevent the drive wheels
from slipping. The EBCM commands the pump
motor and appropriate solenoid valves ON and
OFF to apply brake pressure to the slipping wheel.
Stability Control: Stability control provides added
stability during aggressive maneuvers. Yaw rate is
the rate of rotation about the vehicle's vertical
axis. The stability control is activated when the
EBCM determines that the desired yaw rate does
not match the actual yaw rate as measured by the
yaw rate sensor.
Dynamic Rear Proportioning: The dynamic rear
proportioning is a control system that replaces the
mechanical proportioning valve. Under certain
driving conditions the EBCM will reduce the rear
wheel brake pressure by commanding the
appropriate solenoid valves ON and OFF.
Hydraulic Brake Assist: The hydraulic brake
assist function is designed to support the driver in
emergency braking situations. The EBCM
receives inputs from the brake pressure sensor.
When the EBCM senses an emergency braking
situation, the EBCM will actively increase the
brake pressure to a specific maximum.
Suspension/Electric Power Steering
HiPer Strut Front Suspension
Brakes
This vehicle is equipped with a Continental Teves
Mk60/Mk70 brake system. The electronic brake control
module (EBCM) and the brake pressure modulator
valve assembly are serviced separately. The brake
pressure modulator valve assembly uses a 4 circuit
configuration to control hydraulic pressure to each
wheel independently. The following vehicle
performance enhancement systems are provided:
• Antilock Brake System (ABS): When wheel slip
is detected during a brake application, an ABS
event occurs. During ABS braking, hydraulic
pressure in the individual wheel circuits is
controlled to prevent any wheel from slipping. A
separate hydraulic line and specific solenoid
valves are provided for each wheel. The ABS can
decrease, hold, or increase hydraulic pressure to
each wheel. The ABS does not, however, increase
hydraulic pressure above the amount which is
transmitted by the master cylinder during braking.
• Traction Control: When drive wheel slip is noted,
the EBCM will enter traction control mode. First,
the EBCM requests the engine control module
(ECM) to reduce the amount of torque to the drive
wheels via a serial data message. The ECM
reduces torque to the drive wheels and reports the
amount of delivered torque. If the engine torque

HiPer Strut is a modified MacPherson strut system and
features dual-path top mountings that separate the
transfer of spring and damper loads to the body
structure. This also allows for a shorter spindle length,
thus changing the geometry of the setup, which allows
the tire to maintain negative camber while cornering.
What that means for the driver is improved tire contact
with the pavement under load, reduced torque steer,
more-communicative steering, improved impact

isolation on bumps and rough surfaces and less
kickback in the steering system when the vehicle runs
over imperfections in the road.

Rollover Protection System
Watts Z-Link Rear Suspension
A responsive Watts Z-link design helps center the rear
axle during cornering, which helps keep the Cascada’s
handling responses symmetrical on both left-hand and
right-hand turns. The linkage’s capability to center the
axle during cornering delivers a more-balanced driving
experience because the rear suspension better follows
the lead of the front suspension. The Z-link design is
also lighter and requires less space than a typical fully
independent rear suspension. The lower weight
enhances efficiency, while the compact design enables
the Cascada’s generous cargo room.
Electric Power Steering
Steering inputs are executed by a fuel-saving,
rack-mounted electric power steering system. It does
not have power steering fluid. Regular maintenance is
not required. If power steering assist is lost due to a
system malfunction, the vehicle can be steered, but it
may require increased effort. If the steering wheel is
turned until it reaches the end of its travel and is held
against that position for an extended period of time,
power steering assist may be reduced. Normal use of
the power steering assist should return when the
system cools down.
Traction Control and StabiliTrak®
The vehicle has a Traction Control System (TCS) and
Stabilitrak® which is an electronic stability control
system. These systems help limit wheel spin and assist
the driver in maintaining control, especially on slippery
road conditions.
TCS activates if it senses that any of the drive wheels
are spinning or beginning to lose traction. When this
happens, TCS applies the brakes to the spinning
wheels and reduces engine power to limit wheel spin.
Stabilitrak® activates when the vehicle senses a
difference between the intended path and the direction
the vehicle is actually traveling. The system selectively
applies braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping the vehicle
on the intended path.
If cruise control is being used and TCS or StabiliTrak®
begins to limit wheel spin, the cruise control will
disengage. Cruise control may be turned back ON
when road conditions allow. Both systems turn ON
automatically when the vehicle is started and begins to
move. The systems may be heard or felt while they are
operating or while performing diagnostic checks. This is
normal and does not mean there is a problem with the
vehicle.
⇒ If the vehicle gets stuck in sand, mud, ice, or snow
it may be necessary to turn TCS OFF.
4355431
The Rollover Protection System is controlled by the
Inflatable Restraint Sensing and Diagnostic Module
(SDM). The system activates during a vehicle rollover,
head-on collision or side impact. The system deploys
with the soft top opened or closed.

including the reinforced A-pillars, V-braces, the rollover
bars in an extended state and the reinforced torsion
box bulkhead.
The rollover protection system consists of a reinforced
windscreen frame and rollover bars under covers
behind the rear head restraints. In the event of a vehicle
rollover, head-on collision or side impact, the
pyrotechnically activated, spring-loaded bars deploy
upwards automatically within milliseconds. They also
deploy together with the front and side airbag systems.

ignition is in ON/RUN or ACC/ ACCESSORY, or in
Retained Accessory Power (RAP).
Express Window Operation
Windows with an express-down or up feature allow the
windows to be lowered or raised without holding the
switch. All door windows have the express-down
feature. Front door windows may also have the
express-up feature. Pull a window switch up or push it
down all the way, release it, and the window goes up or
down automatically. Stop the window by pushing or
pulling the switch.
4355458
Express Window Anti-Pinch Feature
If any object is in the path of the window when the
express-up is active, the window will stop at the
obstruction and auto-reverse to a preset factory
position. Weather conditions such as severe icing may
also cause the window to auto-reverse. The window will
return to normal operation after the obstruction or
condition is removed.
DO NOT place any objects on the covers of the rollover
bars behind the head restraints.
The airbag control indicator illuminates if the rollover
bars have been deployed. The soft top MUST NOT be
operated if the rollover bars have been deployed. A
continuous warning will sound and a message appears
in the DIC if the switch is actuated.
Express Window Anti-Pinch Override
To override the anti-pinch feature, hold the window
switch all the way up to the second position. The
window will raise for as long as the switch is held. Once
the switch is released, the express mode is reactivated.
In this mode, the window can close on an object in its
path. Use care when using the override mode.

provides a visual alert and rapidly beeps when
approaching a vehicle directly ahead too quickly.
When this Forward Collision Alert occurs, the
brake system may prepare for driver braking to
occur more rapidly which can cause a brief, mild
deceleration. The Cascada does not illuminate an
amber indicator when following too closely. The
forward-looking FCA camera sensor is on the
windshield ahead of the rearview mirror. FCA
detects vehicles within a distance of
approximately 197 ft (60 m) and operates at
speeds above 25 mph (40 km/h).

Lane Departure Warning (LDW): If equipped,
LDW may help avoid crashes due to unintentional
lane departures. It may provide an alert if the
vehicle is crossing a lane without using a turn
signal in that direction. LDW uses a camera
sensor to detect the lane markings at speeds of
35 mph (56 km/h) or greater. When LDW is ON,
the indicator is green if LDW is available to warn of
a lane departure. If the vehicle crosses a detected
lane marking without using the turn signal in that
direction, the indicator changes to amber and
flashes.
Rear Park Assist (RPA): With RPA, as the
vehicle backs up at speeds of less than 5 mph
(8 km/h), the sensors on the rear bumper detect
objects up to 8 ft (2.5 m) behind the vehicle that
are within a zone 10 in (25 cm) high off the ground
and below bumper level.
Front Park Assist: If equipped with Front Parking
Assist (FPA), it also detects objects 4 ft (1.2 m) in
front of the vehicle.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
