2004 JEEP GRAND CHEROKEE stop start

An advantage of the higher ground clearance is a better
view of the road, allowing you to anticipate problems.
They are not designed for cornering at the same speeds as
conventional 2-wheel drive vehicles any more than low-
slung sports cars are designed to perform satisfactorily in
off-road conditions. If at all possible, avoid sharp turns or
abrupt maneuvers. As with other vehicles of this type,
failure to operate this vehicle correctly may result in loss
of control or vehicle rollover.
OFF-ROAD DRIVING TIPS
When To Use 4 LO (Low) Range
When off-road driving, shift to 4 LO for additional
traction in moving forward or descending a hill, for
low-speed pulling power or to improve handling and
control on slippery or difficult terrain. Also use 4 LO
range on the road in rain, ice, snow, mud or sand to get
heavy loads rolling, or whenever ªHighº range four-
wheel drive traction is insufficient.
In Snow, Mud and Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4 LO if necessary. Don't
shift to a lower gear than necessary to maintain headway.
Over-revving the engine can spin the wheels and traction
will be lost.
Do not downshift on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
Before climbing a steep hill,shift the transmission to a
lower gear and shift the transfer case to 4 LO. Use first
gear and 4 LO for very steep hills.
If you stall or begin to lose headwaywhile climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to R (Reverse). Back slowly down the hill allowing
the compression braking of the engine and transmission
200 STARTING AND OPERATING

WARNING!
Overloading of your tire is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES Ð GENERAL INFORMATION
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:1. SafetyÐ
WARNING!
Improperly inflated tires are dangerous and can
cause accidents.
²Under inflation increases tire flexing and can
result in tire failure.
²Over inflation reduces a tire's ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
²Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
²Overinflated or under inflated tires can affect
vehicle handling and can fail suddenly, resulting in
loss of vehicle control.
Always drive with each tire inflated to the recom-
mended pressure.

Always load a trailer with 60% of the cargo weight in the
front of the trailer. This places approximately 10% to 15%
of the GTW on the tow hitch of your vehicle. This portion
of the GTW becomes the tongue weight.
Trailer sway control and equalizing hitch are required for
tongue weights above 350 lbs (159 kg)., i.e., trailer
weights heavier than 3,500 lbs (1 587 kg).
Cooling System TipsÐTrailer Towing
To reduce potential for engine and transmission over-
heating in high ambient conditions, take the following
actions:
²City Traffic
When stopped, put transmission in N (Neutral) and
increase engine idle speed.
²Highway Driving
Reduce speed.
²Air Conditioning
Turn off temporarily.
To reduce the potential for transmission overheating,
turn the ªOverdriveº off when pulling any trailer or shift
the transmission to Drive position 2 on more severe
grades. Move the shift lever to the next lower position to
eliminate excessive transmission shifting. This action will
also reduce the possibility of transmission overheating
and provide better engine braking.

9. Tighten the lug nuts securely in a crisscross pattern.
Have an authorized service technician check that the
torque is 85-115 ft.lbs. (115-156 N´m) as soon as possible.
10. Secure the jack, lug wrench, jack handle and tire in
the proper locations.WARNING!
²A loose tire or jack thrown forward in a collision
or hard stop could injure someone in the vehicle.
Always stow the jack parts and the extra tire and
wheel in the places provided.
²Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
²Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
²Block the wheel diagonally opposite the wheel to be
raised.
²Apply the parking brake firmly before jacking.
²Never start the engine with the vehicle on a jack.
WHAT TO DO IN EMERGENCIES 245
6

CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturer's specifica-
tions, should be obtained immediately.
