2014 JEEP GRAND CHEROKEE spare tire

QUADRA-LIFT™
The Quadra-Lift™ air suspension system provides full time load leveling capability
along with the benefit of being able to adjust vehicle height by the push of a button.
Quadra-Lift™ is available with both Quadra-Trac II
®and Quadra-Drive II™.
• The system requires that the engine be
running for all changes. When lowering
the vehicle all of the doors, including
the liftgate, must be closed.
• The Quadra-Lift™ air suspension sys-
tem uses a lifting and lowering pattern
which keeps the headlights from shin-
ing into oncoming traffic. When raising
the vehicle, the rear of the vehicle will
move up first and then the front. When
lowering the vehicle, the front will
move down first and then the rear.
• After the engine is turned off, you may
notice that the air suspension system
operates briefly. This is normal. The
system is correcting the position of the vehicle.
• To assist with changing a spare tire, the Quadra-Lift™ air suspension system has
a feature which allows the automatic leveling to be disabled. The feature controls
are located in the radio screen. Driving the vehicle over 5 mph (8 km/h) will return
the air suspension to normal operation.
• An audible chime will be heard whenever a system error has been detected.
Operation
• Pressing the “Up” or “Down” button once will move the suspension one position
higher or lower from the current position, assuming all conditions are met (i.e.,
engine running and all doors and liftgate closed).
• The 4 indicator lamps will illuminate to show the current position of the vehicle.
Flashing indicator lamps will show a position which the system is working to
achieve. If multiple indicator lamps are flashing on the “Up” button, the highest
flashing indicator lamp is the position the system is working to achieve.
• Normal Ride Height (NRH) – This is the standard position of the
suspension and is meant for normal driving. Only the bottom Indicator
lamp on the “Up” button will be illuminated when the vehicle is in this
position.

*For SRT vehicles, do not tow a trailer when using the compact spare tire. Refer to
local laws for maximum trailer towing speeds.
NOTE: The trailer tongue weight must be considered as part of the combined weight of
occupants and cargo, and should never exceed the weight referenced on the Tire and
Loading Information placard.
If the gross trailer weight is 3,500 lbs (1587 kg) or more, it is mandatory to use a
weight-distributing hitch to ensure stable handling of your vehicle.

INSTRUMENT CLUSTER WARNING LIGHTS
- Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly, when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a Tire Pressure
Monitoring System (TPMS) which display in the Electronic Vehicle Information
Center (EVIC) when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure EVIC display illuminates, you should stop and
check your tires as soon as possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
After inflation, the vehicle may need to be driven for 20 minutes before the flashing light
will turn off.

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 the transmission to 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 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.
JACKING AND TIRE CHANGING
Run Flat Tires — SRT Only
This vehicle is equipped with “run flat” tires. Run flat tires allow the vehicle to be
driven approximately 50 miles (80km) at 55 mph (88km/h). Tire service should be
obtained to avoid prolonged run flat feature usage.
NOTE:
This vehicle may be equipped with a spare tire. The spare tire must be used for the
rear wheel(s) only. For a flat front tire, move the rear tire to the front and use the spare
tire on the rear.

vehicle and install the lug nuts with
the cone-shaped end toward the wheel.
Lightly tighten the nuts.
9. Lower the vehicle by turning the jack
screw counterclockwise, and remove
the jack and wheel blocks.
10. Finish tightening the lug nuts. Push
down on the wrench while at the end
of the handle for increased leverage.
Tighten the lug nuts in a star pattern
until each nut has been tightened
twice. The correct wheel nut tight-
ness is 130 ft lbs (176 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.
11. Lower the jack to the fully closed position and return it and the tools to the
proper positions in the foam tray.
12. Remove the small center cap and securely store the road wheel in the cargo area.
13. Have the aluminum road wheel and
tire repaired as soon as possible,
properly secure the spare tire with
