2007 JEEP GRAND CHEROKEE wheel

CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment and Balance
Poor suspension alignment may result in:
²Fast tire wear.
²Uneven tire wear, such as feathering and one-sided
wear.
²Vehicle pull to right or left.
Tires may also cause the vehicle to pull left or right.
Alignment will not correct this problem. See your autho-
rized dealer for proper diagnosis.Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE ROTATION RECOMMENDATIONS
Do not rotate the tires as the wider rear tires will not fit
on the front of the vehicle.
TIRE PRESSURE MONITOR SYSTEM (TPMS)
Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure
readings to the Receiver Module. The wheel sensors
monitor tire pressure, and status for all four active road
tires.
266 STARTING AND OPERATING

NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The ªTire Pressure Monitoring Telltale Lightº will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more
tire pressures is low. The ªTire Pressure Monitoring
Telltale Lightº will flash on and off for 60 seconds when
a system fault is detected. The flash cycle will repeat
every ten minutes or until the fault condition is removed
and reset.
The Tire Pressure Monitoring System (TPMS) consists of
the following components:
²Receiver Module
²4 Wheel Sensors
²3 Wheel Sensor Trigger Modules
²Tire Pressure Monitoring System Display Messages in
the EVIC
²Tire Pressure Monitoring Telltale Light
The system consists of tire pressure monitoring sensors
attached to each wheel through the valve stem mounting
hole, a central receiver module, Wheel Sensor Trigger
Modules mounted in three of the four wheel wells,
various Tire Pressure Monitoring System Display Mes-
sages in the EVIC, and a ªTire Pressure Monitoring
Telltale Light.º
NOTE:For vehicles with optional wheel/tire sizes and
significantly different tire placard pressures, the placard
pressure value and the low-pressure threshold value is
re-programmable at your authorized dealer to accommo-
date the customer selected wheel/tire combinations rec-
ommended by DaimlerChrysler Corporation.
STARTING AND OPERATING 267

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to
the sensors may result.
CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the wheel rim sensor.
NOTE:
²The TPMS can inform the driver of a low tire pressure
condition.
²The TPMS is not intended to replace normal tire care
and maintenance, nor to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/
TransmissionGCWR (Gross Combined
Wt. Rating)Frontal Area Max. GTW (Gross
Trailer Wt.)Max. Tongue Wt.
(See Note 1)
6.1L Automatic 8,800 lbs (3 992 kg) 40 Sq. Ft. (3.72
square meters)3,500 lbs (1 587 kg) 350 lbs (159 kg)
Refer to local laws for maximum trailer towing speeds.
Note 1 ± 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. Refer to the Tire±
Safety Information Section in this manual.
Trailer and Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to swayseverelyside to side
which will cause loss of control of vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents.
282 STARTING AND OPERATING

²Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
²Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle in P (Park). Always, block
or9chock9the trailer wheels.
²GCWR must not be exceeded.
²Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
Towing Requirements Ð Tires
þ
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
ªTires±General Informationº for proper tire inflation
procedures.
þAlso, check the trailer tires for proper tire inflation
pressures before trailer usage.
þCheck for signs of tire wear or visible tire damage
before towing a trailer. Refer to ªTires±General Infor-
mationº for proper inspection procedure.

298 MAINTAINING YOUR VEHICLE

²Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle is drivenregularlyfor
more than 45 minutes of continuous operation.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
Front And Rear Wheel Bearings
Front and rear wheel bearings are permanently sealed.
No regular maintenance is required for these compo-
nents.
Appearance Care And Protection From Corrosion
Protection of Body and Paint from Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle.The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
²Road salt, dirt and moisture accumulation.
²Stone and gravel impact.
²Insects, tree sap and tar.
²Salt in the air near seacoast localities.
²Atmospheric fallout/industrial pollutants.
MAINTAINING YOUR VEHICLE 329

²If your vehicle is damaged due to an accident or
similar cause which destroys the paint and protective
coating have your vehicle repaired as soon as possible.
The cost of such repairs is considered the responsibil-
ity of the owner.
²If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., assure that such materials are well
packaged and sealed.
²If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
²Use MopartTouch Up Paint on scratches or chips as
soon as possible. Your authorized dealer has touch up
paint to match the color of your vehicle.
Wheel and Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To removeheavy soil, use MopartWheel Cleaner or select a non-
abrasive, non-acidic cleaner. Do not use scouring pads,
steel wool, a bristle brush or metal polishes. Only Mo-
partcleaners are recommended. Do not use oven cleaner.
Avoid automatic car washes that use acidic solutions or
harsh brushes that may damage the wheels' protective
finish.
Interior Care
Use MopartTotal Clean to clean fabric upholstery and
carpeting.
Interior Trim should be cleaned starting with a damp
cloth, a damp cloth with MopartTotal Clean, then
MopartSpot & Stain Remover if absolutely necessary. Do
not use harsh cleaners or Armorall. Use MopartTotal
Clean to clean vinyl upholstery.
Leather Seat Care & Cleaning
MopartTotal Clean is specifically recommended for
leather upholstery.
