If Your Engine Overheats - Jeep wrangler User Manual

WHAT TO DO IN EMERGENCIES
HOTOIL – Transmission Temperature Warning Message
• The HOTOIL cluster message will appear in the odometer accompanied with a
chime to indicate that there is excessive transmission 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 4-wheel-drive operation (e.g., snow plowing, off-road
operation).
• If this HOTOIL message turns on, stop the vehicle and run the engine at idle or
faster, with the transmission in NEUTRAL until the message turns off.
Continuous driving with the Transmission Temperature HOTOIL Warning
message illuminated will eventually cause severe transmission damage and
transmission failure.
Continued operation with the Transmission Temperature HOTOIL Warning
message illuminated could cause the fluid to boil over, come into contact with the
hot engine or exhaust components causing a fire that may result in personal
injury.

IF YOUR ENGINE OVERHEATS

• In any of the following situations, you can reduce the potential for overheating
by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into NEUTRAL, but do not
increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending overheat
condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the
engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the Temperature Control to maximum heat, the Mode Control
to floor and the Fan Control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat from the engine cooling
system.
• If the temperature reading does not return to normal, turn the engine off
immediately.
• We recommend that you do not operate the vehicle or engine damage will occur.
Have the vehicle serviced immediately.
