• SERV 4WD Warning Light
This light monitors the electric shift 4WD sys-
tem. If the SERV 4WD warning light stays on or
comes on during driving, it means that the
4WD system is not functioning properly and
that service is required.
• Transmission Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as four-wheel drive
operation (e.g., snow plowing, off-road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the “Transmission Tem-
perature Warning Light” illuminated will eventually
cause severe transmission damage or transmission
failure.
WARNING!
In some circumstances, the “Transmission Tempera-
ture Warning Light” under continued operation,
could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a
fire.
