SERVICE 4 WHEEL DRIVE
If your vehicle has the
all-wheel-drive (AWD) system or the
four-wheel-drive (4WD) system, this
message displays if a problem
occurs with the system. If this
message appears, stop as soon as
possible and turn off the vehicle.
Make sure the key is in LOCK/OFF
for at least one minute and then
restart the vehicle and check for the
message on the DIC display. If the
message is still displayed or
appears again when you begin
driving, the AWD or 4WD system
needs service. See your dealer.
, TRANSMISSION HOT IDLE
ENGINE
Do not drive the vehicle
while the transmission fluid is
overheating and the transmission
temperature warning is displayed
on the instrument cluster and/or
DIC, or the transmission can be
damaged. This could lead to
costly repairs that would not be
covered by the warranty.
This message displays along with
four chimes if the transmission fluid
in the vehicle gets hot. Driving with
the transmission fluid temperature
high can cause damage to the
vehicle. Stop the vehicle and let it
idle to allow the transmission to
cool. This message clears and the
chime stops when the fluid
temperature reaches a safe level.
