overheating JEEP GRAND CHEROKEE 2016 WK2 / 4.G User Guide

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, place the transmission in NEUTRAL, but do notincrease the engine idle speed while preventing vehicle motion with the brakes.
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 blower 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.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.
WHAT TO DO IN EMERGENCIES

NOTE:
Push the "ESC Off" switch (if necessary), to place the Electronic Stability Control
(ESC) system in "Partial Off" mode, before rocking the vehicle. Refer to “Electronic
Brake Control” in “Starting And Operating” in the Owners Manual on the DVD for
further information. Once the vehicle has been freed, push the "ESC Off" switch
again to restore "ESC On" mode.
CAUTION!
Racing the engine or spinning the wheels may lead to transmission overheating
and failure. Allow the engine to idle with the transmission in NEUTRAL for at least
one minute after every five rocking-motion cycles. This will minimize overheating
and reduce the risk of transmission failure during prolonged efforts to free a stuck
vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause damage, or even failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without stopping when you are stuck
and do not let anyone near a spinning wheel, no matter what the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, donot spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast may lead to transmission
overheating and failure. It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).
