If Your Engine Overheats - Jeep 2006 Wrangler Owner's Manual

Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE: With extended use, the flasher may wear down
your battery.

IF YOUR ENGINE OVERHEATS

In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
• On the highways — Slow down.
WHAT TO DO IN EMERGENCIES 253
• In city traffic — While stopped, put transmission in N
(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
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes 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.
