2011 JEEP GRAND CHEROKEE Owners Manual

•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.

6. Raise the vehicle by turning the jack screw clockwise.
Raise the vehicle only until the tire just clears the surface
and enough clearance is obtained to install the spare tire.
Minimum tire lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
7. Remove the lug nuts and wheel.
8. Position the spare wheel/tire on the vehicle and install
the lug nuts with the cone-shaped end toward the wheel.
Lightly tighten the nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the wheel nuts fully until the vehicle
has been lowered.
9. Lower the vehicle by turning the jack screw counter-
clockwise, and remove the jack and wheel blocks.
10. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
nuts until each nut has been tightened twice. The correct
wheel nut tightness is 110 ft lbs (150 N·m). If in doubt
about the correct tightness, have them checked with a
torque wrench by your authorized dealer or at a service
station.
