2012 JEEP GRAND CHEROKEE load capacity

ROOF LUGGAGE RACK — IF EQUIPPED
The crossbars and siderails are designed to carry the
weight on vehicles equipped with a luggage rack. The
load must not exceed 150 lbs (68 kg), and should be
uniformly distributed over the luggage rack crossbars.
NOTE:If not equipped with crossbars, your authorized
dealer can order and install MOPARcrossbars built
specifically for this roof rack system.
Distribute cargo weight evenly on the roof rack crossbars.
The roof rack does not increase the total load carrying
capacity of the vehicle. Be sure the total load of cargo
inside the vehicle plus that on the external rack does not
exceed the maximum vehicle load capacity.
To move the crossbars, loosen the attachments, located at
the upper edge of each crossbar, approximately eight
turns using the anti-theft wrench provided with the
MOPARcrossbars. Then, move the crossbar to the
desired position, keeping the crossbars parallel to therack frame. Once the crossbar is in the desired position,
retighten the with the wrench to lock the crossbar into
position.
NOTE:
•To help control wind noise when the crossbars are not
in use, place the front and rear crossbars approxi-
mately 24 in (61 cm) apart. Optimal noise reduction
can then be achieved by adjusting the front crossbar
forward or aft using increments of 1 in (2.5 cm).
•If the rear crossbar (or any metallic object) is placed
over the satellite radio antenna (if equipped), you may
experience interruption of satellite radio reception. For
improved satellite radio reception, avoid placing the
rear crossbar over the satellite radio antenna.
•The grab handles on the back of the vehicle (if
equipped) are not to be used as a towing feature.

CAUTION!
•To prevent damage to the roof of your vehicle, do
not carry any loads on the roof rack without the
crossbars installed. The load should be secured
and placed on top of the crossbars, not directly on
the roof. If it is necessary to place the load on the
roof, place a blanket or some other protection
between the load and the roof surface.
•To avoid damage to the roof rack and vehicle, do
not exceed the maximum roof rack load capacity of
150 lbs (68 kg). Always distribute heavy loads as
evenly as possible and secure the load appropri-
ately.
(Continued)
CAUTION! (Continued)
•Long loads which extend over the windshield,
such as wood panels or surfboards, or loads with
large frontal area should be secured to both the
front and rear of the vehicle.
•Travel at reduced speeds and turn corners care-
fully when carrying large or heavy loads on the
roof rack. Wind forces, due to natural causes or
nearby truck traffic, can add sudden upward lift to
a load. This is especially true on large flat loads
and may result in damage to the cargo or your
vehicle.3

Tire Terminology And Definitions
Term Definition
B-PillarThe vehicle B-Pillar is the structural member of the body located
behind the front door.
Cold Tire Inflation PressureCold tire inflation pressure is defined as the tire pressure after the
vehicle has not been driven for at least 3 hours, or driven less
than 1 mile (1.6 km) after sitting for a three hour period. Inflation
pressure is measured in units of PSI (pounds per square inch) or
kPa (kilopascals).
Maximum Inflation PressureThe maximum inflation pressure is the maximum permissible cold
tire inflation pressure for this tire. The maximum inflation pres-
sure is molded into the sidewall.
Recommended Cold Tire Inflation Pres-
sureVehicle manufacturer’s recommended cold tire inflation pressure
as shown on the tire placard.
Tire PlacardA paper label permanently attached to the vehicle describing the
vehicle’s loading capacity, the original equipment tire sizes and
the recommended cold tire inflation pressures.

Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire’s load carrying capacity if you
adhere to the loading conditions, tire size, and cold tire
inflation pressures specified on the Tire and Loading
Information placard and in the “Vehicle Loading” section
of this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
“Vehicle Loading” in this section.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX lbs or
XXX kg” on the Tire and Loading Information placard.The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps For Determining Correct Load Limit
1. Locate the statement “The combined weight of occu-
pants and cargo should never exceed XXX lbs or XXX kg”
on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas-
sengers from XXX lbs or XXX kg.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “XXX”
amount equals 1,400 lbs (635 kg) and there will be five
150 lb (68 kg) passengers in your vehicle, the amount of
5
STARTING AND OPERATING 415

available cargo and luggage load capacity is 650 lbs
(295 kg) (since 5 x 150 = 750, and 1400 – 750 = 650 lbs
[295 kg]).
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.NOTE:
•The following table shows examples on how to calcu-
late total load, cargo/luggage, and towing capacities
of your vehicle with varying seating configurations
and number and size of occupants. This table is for
illustration purposes only and may not be accurate for
the seating and load carry capacity of your vehicle.
•For the following example, the combined weight of
occupants and cargo should never exceed 865 lbs
(392 kg).
416 STARTING AND OPERATING

WARNING!
Overloading of your tires 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 — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:
Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause collisions.
•Under-inflation increases tire flexing and can re-
sult in over-heating and tire failure.
•Over-inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.
•Over-inflated or under-inflated tires can affect
vehicle handling and can fail suddenly, resulting
in loss of vehicle control.
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
(Continued)
418 STARTING AND OPERATING

loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle at or above
maximum load is dangerous. The added strain on
your tires could cause them to fail. You could have a
serious collision. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision. Al-
ways use radial tires in sets of four. Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized dealer for radial tire repairs.
Spare Tire Matching Original Equipped Tire And
Wheel – If Equipped
Your vehicle may be equivalent with a spare tire and
wheel in look and function as the original equipment tire
and wheel found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rotation for your
5
STARTING AND OPERATING 421

WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
a collision resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.
•Never use a tire with a smaller load index or
capacity than what was originally equipped on
your vehicle. Using a tire with a smaller load index
could result in tire overloading and failure. You
could lose control and have a collision.
(Continued)
WARNING! (Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
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
