2014 JEEP GRAND CHEROKEE towing 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 MOPAR® crossbars 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
MOPAR® crossbars. Then, move the crossbar to the desired position, keeping the crossbars parallel to the
rack 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.

3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, andspare tires.
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 ofcargo 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 available cargo and luggage load capacity
is 650 lbs (295 kg) (since 5 x 150 lbs (68 kg) = 750 lbs
(340 kg), and 1400 lbs (635 kg) – 750 lbs (340 kg) =
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. NOTE:
•
If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. The follow-
ing table shows examples on how to calculate total
load, cargo/luggage, and towing capacities of your
vehicle with varying seating configurations and num-
ber 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).
436 STARTING AND OPERATING

The suggested rotation method is the “forward-cross”
shown in the following diagram.TIRE PRESSURE MONITOR SYSTEM (TPMS)
NOTE:For vehicles equipped with run flat tires — When
the TPMS indicates a tire pressure of 14 psi (96 kPa) or
lower, always check tire pressure and replace the tire at
the first opportunity. At inflation pressure of/or below
14 psi (96 kPa) the tire is in the run-flat mode of
operation. In this condition, it is recommended a vehicle
maximum speed of 50 mph (80 km/h) for a maximum
distance of 50 miles (80 km). Chrysler Group LLC does
not recommend using the run flat feature while driving a
vehicle loaded at full capacity or towing a trailer.
The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold tire pressure.

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. Refer to “Tire–Safety
Information” in “Starting and Operating” for further
information.
• Chrysler Group LLC does not recommend using the
run flat feature while driving a vehicle loaded at full
capacity or towing a trailer.
Trailer And Tongue Weight
Always load a trailer with 60% of the weight in the front
of the trailer. This places 10% of the GTW on the tow
hitch of your vehicle. Loads balanced over the wheels or
heavier in the rear can cause the trailer to sway severely
side to side which will cause loss of control of the vehicle
and trailer. Failure to load trailers heavier in front is the
cause of many trailer collisions. Never exceed the maxi-
mum tongue weight stamped on your trailer hitch.
474 STARTING AND OPERATING

Towing Requirements — Trailer Brakes
WARNING!
•Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
•Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances. •
Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
1,653 lbs (750 kg).Towing Requirements — Tires
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
478 STARTING AND OPERATING

•Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
• Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for proper
inspection procedure.
• When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Tips
NOTE: To provide optimum towing performance and to
protect transmission components always select Trailer
Tow mode when towing a trailer. Before setting out on a
trip, practice turning, stopping and backing the trailer in
an area away from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent shift-
ing does occur while in DRIVE, select TOW mode, or use
the Paddle Shift switches to manually select a lower gear.
NOTE: Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
TOW Mode
To reduce the potential for automatic transmission over-
heating, select TOW mode when driving in hilly areas, or
select a lower gear (using the Paddle Shift switches) on
more severe grades.
