ATF LEVEL CHECK
Before You Start
1. Connect the i-HDS. Go to the A/T Data List, and scroll down to ATF Temperature.
2. Raise the vehicle on a lift, remove the engine undercovers (if needed), and slightly loosen the level plug.
3. Enter VSA Maintenance Mode
NOTE: You must enter this mode to complete the ATF level check; it disables the VSA and TCS functions. Be sure
to complete all of the following steps within 30 seconds, or you’ll need to start over.
4. Turn the ignition to ON.
5. Press and hold the brake pedal, and release the parking brake.
6. Press and hold the VSA OFF switch until the VSA OFF indicator comes on. Then, press the switch again until the
indicator goes out.
7. Release the brake pedal, and set the parking brake.
8. Press and hold the VSA OFF switch until the VSA OFF indicator comes on. Then, press the switch again until the
indicator goes out.
9. Press and hold the brake pedal.
10. Press the VSA OFF switch. If the VSA OFF indicator comes on, press the switch again and release it. If successful,
the VSA OFF indicator starts blinking and the VSA indicator comes on. You are now in VSA maintenance mode. To
exit this mode, either turn the ignition switch to OFF or quickly press and release the VSA OFF switch, making sure
the VSA OFF and VSA indicators go out.
Check the ATF Level
11. Start the engine, and wait for the transmission temperature to reach 90°F.
NOTE: If the temperature is more than 115°F (the vehicle may have been recently driven), shut off the engine and
let the transmission cool down before continuing.
12. Shift to Drive, then press the D/S button again to enter sequential mode.
13. Using the paddle shifters, shift to 1st, 2nd, 3rd, then 4th gear. Then, shift back to 3rd, 2nd, and 1st gear.
IMPORTANT: Do not shift past 4th gear with the vehicle on the lift; you could damage the transmission.
14. Apply the brakes to stop the wheels from spinning, then shift to Park.
15. Raise the engine speed to 2,000 rpm for about 5 seconds, then release the accelerator pedal. Repeat this until the
transmission temperature reaches about 100°F, then wait for the temperature to reach 104 to 115°F.
NOTE: The ideal temperature for checking the ATF level is 104°F. If it’s more than 115°F, shut off the engine, let
the transmission cool down, and start over again.

16. With the engine running, remove the level plug.
IMPORTANT: With the level plug removed, you must keep the engine running. If you shut it off, the ATF will pour
out of the transmission.
• If a small amount of ATF trickles out of the level plug hole and keeps doing so, the level is OK. Install a new
level plug, and torque it to 35 N·m (26 lb-ft).
• If no ATF comes out, loosely install a new level plug and lower the vehicle. Remove the fill plug, and add the
appropriate amount of ATF Type 3.1 through the fill plug hole. Then, install a new fill plug, and check the ATF
level again by removing the level plug. Be sure to monitor the ATF temperature while doing this. When you’re
done, install the level plug, then torque the level and fill plugs to 35 N·m (26 lb-ft).
17. Install the engine undercovers (if removed).
18. Turn the engine off.
