ESP JEEP GRAND CHEROKEE 2011 WK2 / 4.G Service Manual

Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states pro-
hibit studded tires; therefore, local laws should be
checked before using these tire types.
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates.These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off-Road
type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
NOTE:
The premium Tire Pressure Monitor System will
automatically locate the pressure values displayed in the
correct vehicle position following a tire rotation.
The suggested rotation method is the “forward-cross”
shown in the following diagram.
414 STARTING AND OPERATING

CAUTION! (Continued)
•After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.
NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire 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.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base 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.
NOTE: It is particularly important, for you to regularly
check the tire pressure in all of your tires, and to maintain
the proper pressure.

STARTING AND OPERATING 417

CAUTION!
DO NOT use gasoline containing Methanol or gaso-
line containing more than 10% Ethanol. Use of these
blends may result in starting and driveability prob-
lems, damage critical fuel system components, cause
emissions to exceed the applicable standard, and/or
cause the “Malfunction Indicator Light” to illumi-
nate. Pump labels should clearly communicate if a
fuel contains greater than 10% Ethanol.
Problems that result from using gasoline containing
Methanol or gasoline containing more than 10% Ethanol
are not the responsibility of the manufacturer and may
not be covered under warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty. If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold driveability
•increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•change the engine oil and oil filter
•disconnect and reconnect the battery
•drain the fuel tank (see your authorized dealer)
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
426 STARTING AND OPERATING

CAUTION! (Continued)
•An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer.
NOTE: Intentional tampering with the emissions con-
trol system can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
(Continued)
428 STARTING AND OPERATING

12. Securely store the road wheel and jack in the cargo
area.
13. Have the aluminum road wheel and tire repaired as
soon as possible, properly secure the spare tire with thespecial wing nut torqued to 3.7 ft-lbs (5 N·m), reinstall the
jack and tool kit foam tray, and latch the rear load floor
cover.
WARNING!
A loose tire or jack, thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.
JUMP-STARTING
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.

WHAT TO DO IN EMERGENCIES 471

CAUTION! (Continued)
•This vehicle has not been designed for use with
Propylene Glycol-based engine coolant (anti-
freeze). Use of Propylene Glycol-based engine
coolant (antifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (antifreeze) that allows extended maintenance
intervals. This engine coolant (antifreeze) can be used up
to 5 Years or 104,000 miles (169 000 km) before replace-
ment. To prevent reducing this extended maintenance
period, it is important that you use the same engine
coolant (antifreeze) throughout the life of your vehicle.
Please review these recommendations for using Hybrid
Organic Additive Technology (HOAT) engine coolant
(antifreeze).When adding engine coolant (antifreeze):
•The manufacturer recommends using MOPAR

Antifreeze/ Coolant 5–Year/100,000 Mile Formula HOAT
(Hybrid Organic Additive Technology) or equivalent.
•Mix a minimum solution of 50% HOAT engine coolant
(antifreeze) and distilled water. Use higher concentra-
tions (not to exceed 70%) if temperatures below -34°F
(-37°C) are anticipated.
•Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
engine cooling system.
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
504 MAINTAINING YOUR VEHICLE

•Avoid using abrasive compounds and power buffing
that may diminish the gloss or thin out the paint
finish.
CAUTION!
•Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder, which will
scratch metal and painted surfaces.
•Use of power washers exceeding 1,200 psi
(8 274 kPa) can result in damage or removal of
paint and decals.
Special Care
•
If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least once
a month.
•It is important that the drain holes in the lower edges
of the doors, rocker panels and tailgate must be kept
clear and open.
•If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
•If your vehicle is damaged due to a collision 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 responsibility of
the owner.
•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., assure that such materials are well
packaged and sealed.
•If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
516 MAINTAINING YOUR VEHICLE

•Use MOPARTouch Up Paint or equivalent 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 remove
heavy soil, use MOPAR Wheel Cleaner or select a
nonabrasive, non-acidic cleaner. Do not use scouring
pads, steel wool, a bristle brush or metal polishes. Only
MOPAR cleaners or equivalent 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.
Stain Repel Fabric Cleaning Procedure –

Interior Care
Use MOPARTotal Clean or equivalent to clean fabric
upholstery and carpeting.
Interior Trim should be cleaned starting with a damp
cloth, a damp cloth with MOPAR Total Clean or equiva-
lent, then MOPAR Spot & Stain Remover or equivalent,
if absolutely necessary. Do not use harsh cleaners or
Armor All. Use MOPAR Total Clean or equivalent to
clean vinyl upholstery.
Leather Seat Care And Cleaning
MOPAR Total Clean or equivalent is specifically recom-
mended for leather upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and MOPAR Total Clean or equivalent. Care should be taken to avoid soaking your leather upholstery with any
liquid. Please do not use polishes, oils, cleaning fluids,
solvents, detergents, or ammonia-based cleaners to clean
your leather upholstery. Application of a leather condi-
tioner is not required to maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas, they may cause respiratory harm.
Cleaning Headlights
Your vehicle has plastic headlights that are lighter and
less susceptible to stone breakage than glass headlights.
Plastic is not as scratch-resistant as glass and therefore
different lens cleaning procedures must be followed.
518 MAINTAINING YOUR VEHICLE

Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
