Transmission Messages
SERVICE 4 WHEEL DRIVE
If the vehicle has four-wheel drive,
this message may display if a
problem occurs with the
four-wheel-drive system. If this
message appears, stop as soon as
possible and turn off the vehicle.
Make sure the key is in the LOCK/
OFF position 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
four-wheel-drive system needs
service. See your dealer.
