2010 JEEP GRAND CHEROKEE inflation pressure

the level to trigger the display of the “TPM
Telltale Light” and the “TIRE LOW PRES-
SURE” message.
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Base SystemThe Tire Pressure Monitor System (TPMS) uses
wireless technology with wheel rim-mounted
electronic sensors to monitor tire pressure lev-
els. 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 regu-
larly check the tire pressure in all of your
tires, and to maintain the proper pressure.
The TPMS consists of the following compo-
nents:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light A low spare tire will not cause the “Tire Pressure
Monitoring Telltale Light” to illuminate, a warn-
ing message to appear, or the chime to sound.
The “Tire Pressure Monitoring Telltale
Light” will illuminate in the instrument
cluster, a “TIRE LOW PRESSURE”
message will display in the instrument
cluster for 5 seconds, and an audible chime will
be activated, when one or more of the four
active road tire pressures are low. Should this
occur, you should stop as soon as possible,
check the inflation pressure of each tire on your
vehicle, and inflate each tire to the vehicle’s
recommended cold placard pressure value.
The system will automatically update and the
“Tire Pressure Monitoring Telltale Light” will
extinguish, once the updated tire pressures
have been received. The vehicle may need to
be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
The “Tire Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds, and remain on
solid when a system fault is detected. In addi-
tion, a “SERVICE TPM SYSTEM” message may
be displayed for approximately 5 seconds
when a system fault is detected, and a chime will sound. If the ignition switch is cycled, this
sequence will repeat, providing the system
fault still exists. The “Tire Pressure Monitoring
Telltale Light” will turn off when the fault condi-
tion no longer exists. A system fault can occur
by any of the following:
1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same Radio
Frequencies as the TPM sensors.
2. Installing some form of aftermarket window
tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM
sensors.
NOTE:
There is no tire pressure monitoring sensor
in the spare tire. The TPMS will not be able to
monitor the tire pressure. If you install the
spare tire, in place of a road tire, that has a
pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a
chime will sound, a “TIRE LOW PRESSURE”

thorized dealer-installed options, must be
considered as part of the total load on your
vehicle.
Towing RequirementsTo promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
CAUTION!
•Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts
could be damaged.
• Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts at
full throttle. This helps the engine and other
parts of the vehicle wear in at the heavier
loads.
Perform the maintenance listed in the “Mainte-
nance Schedule.” Refer to “Maintenance
Schedule” for the proper maintenance inter-
vals. When towing a trailer, never exceed the
GAWR or GCWR ratings.
WARNING!
Improper towing can lead to an injury acci-
dent. Follow these guidelines to make your
trailer towing as safe as possible:
•
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured, dy-
namic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have an accident.
• When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over-
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspen-
sion, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always con-
nect the chains to the hook retainers of the
vehicle hitch. Cross the chains under the
trailer tongue and allow enough slack for
turning corners.
(Continued)
WARNING!(Continued)
• Vehicles with trailers should not be parked
on a grade. When parking, apply the park-
ing brake on the tow vehicle. Put the tow
vehicle transmission in PARK. For four-
wheel drive vehicles, make sure the trans-
fer case is not in NEUTRAL. Always, block
or chock the trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed be-
tween the tow vehicle and the trailer
such that the following four ratings are
not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Trailer tongue weight rating for the trailer
hitch utilized.
Towing Requirements – Tires
Proper tire inflation pressures are essential to the safe and satisfactory operation of your
vehicle. Refer to “Tires – General Informa-
tion” in “Starting and Operating” for proper
tire inflation procedures.
247

Check the trailer tires for proper tire inflationpressures 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 – Gen- eral Information” in “Starting and Operating”
for proper tire replacement procedures. Re-
placing tires with a higher load carrying
capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes
Do notinterconnect the hydraulic brake sys-
tem or vacuum system of your vehicle with
that of the trailer. This could cause inad-
equate braking and possible personal injury.
An electronically-actuated trailer brake con- troller 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 1,654 lbs (750 kg).
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.
WARNING!
• Do not connect trailer brakes to your vehi-
cle’s hydraulic brake lines. It can overload
your brake system 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 stop-
ping distance. 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. Towing Requirements – Trailer Lights and
Wiring
Whenever you pull a trailer, regardless of the
trailer size, stop lights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package includes a 13 pin
wiring harness. Use a factory approved trailer
harness and connector.
NOTE:
Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to a
trailer connector.
