 Let the vehicle cool down until the coolant temperature has dropped below 104°F. Then check the coolant
level in the coolant expansion tank and fill it to the maximum line.
Pre-Delivery inspection:
 Due to the very large cooling system, R8 vehicles are leaving the factory with a slightly overfilled cooling
system to compensate for a possible drop in the coolant level. Observe the information in the repair manual or
the maintenance tables:
 Do not correct the overfilled coolant tank during the PDI.
 During all other services where the cooling system has to be checked, the coolant level must be checked at
a coolant temperature below 104°F and if necessary fill to the maximum line only.
Warranty
Claim Type:
 110 up to 48 Months/50,000 Miles.
