2010 JEEP GRAND CHEROKEE four wheel drive

Inflation pressures specified on the chart are
always “Cold Inflation Pressure.” Cold inflation
pressure is defined as the tire pressure after the
vehicle has been idle for at least three hours, or
driven less than a mile (1.6 km) after a three-
hour period. The cold inflation pressure must
not exceed the maximum values molded into
the tire sidewall.
Tire pressures may increase from 2 to 6 psi
(0.14 to 0.41 bar) [14 to 41 kPa] during opera-
tion. DO NOT reduce this normal pressure
buildup.
High Speed OperationThe manufacturer advocates driving at safe
speeds within posted speed limits. Where
speed limits or conditions are such that the
vehicle can be driven at high speeds, correct
tire inflation pressure is very important.
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 an
accident. Always 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 dealer for radial tire re-
pairs.
Tire SpinningWhen stuck in mud, sand, snow, or ice condi-
tions, do not spin your vehicle’s wheels above
30 mph (48 km/h).
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle’s wheels faster than 30 mph (48 km/h)
when you are stuck, and do not let anyone
near a spinning wheel, no matter what the
speed.
Tire ChainsUse of traction devices require sufficient tire-to-
body clearance. Follow these recommenda-
tions to guard against damage.
• Install on Rear Tires Only
• Due to limited clearance, use SAE class “S”
low profile cables or traction devices only.
Security Chain Company (SCC) Super Z6
#SZ 441 cables or equivalent are recom-
mended.

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”
236

message will be displayed in the instrument
cluster, and the “Tire Pressure Monitoring
Telltale Light” will turn ON. After driving the
vehicle for up to 20 minutes above 15 mph
(25 km/h), the “Tire Pressure Monitoring
Telltale Light” will flash on and off for
75 seconds and then remain on solid. In
addition, a “SERVICE TPM SYSTEM” mes-
sage will be displayed. For each subsequent
ignition switch cycle, a chime will sound, a
“SERVICE TPM SYSTEM” message will be
displayed, and the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for
75 seconds and then remain on solid. Once
you repair or replace the original road tire,
and reinstall it on the vehicle in place of the
spare tire, the TPMS will update automati-
cally and the “Tire Pressure Monitoring Tell-
tale Light” will turn OFF, as long as no tire
pressure is below the low-pressure warning
limit in any of the four active road tires. The
vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order
for the TPMS to receive this information.Premium System – If EquippedThe 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 Tire Pressure Monitor System (TPMS) con-
sists of the following components:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
• Various Tire Pressure Monitoring System
Messages, which display in the Electronic
Vehicle Information Center (EVIC), and a
graphic displaying tire pressures Tire Pressure Monitoring Low Pressure
Warnings
When one or more of the four active road tire
pressures are low, the “TPM Telltale Light” will
illuminate, an audible chime will sound, the
EVIC will display “Low Tire Pressure” message
for a minimum of five seconds, and a graphic
display of the pressure value(s) with the low
tire(s) “flashing.” Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.
237

Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible, and inflate the low tire(s) that is
“flashing” on the graphic display to the vehi-
cle’s recommended cold tire pressure. The
system will automatically update, the graphic
display of the pressure value(s) will stop “flash-
ing,” and the Low Pressure text message(s) will
switch off once the updated tire pressure(s)
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.
SERVICE TPM SYSTEM Warning
When a system fault is detected, the “TPM
Telltale Light” will flash on and off for 75 sec-
onds then remain on solid, and a chime will
sound. The EVIC will display a “SERVICE TPM
SYSTEM” message. This message is then fol-
lowed by a graphic display, with “- -“ in place of
the pressure value(s), indicating which Tire
Pressure Monitoring Sensor(s) is not being re-
ceived.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.If the ignition switch is cycled, this sequence
will repeat, providing the system fault still ex-
ists. If the system fault no longer exists, the
“TPM Telltale Light” will no longer be illumi-
nated, the “SERVICE TPM SYSTEM
message
will not be present, and a pressure value will be
displayed instead of dashes. 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.
The “TPM Telltale Light” will also flash on and
off for 75 seconds and then remain on, and the
EVIC will display a
SERVICE TPM SYSTEM 
message when a system fault is detected pos-
sibly related to an incorrect sensor location
fault. In this case, the SERVICE TPM SYSTEM 
message is then followed by a graphic display,
with pressure values still shown. This indicates
the pressure values are still being received
from the TPM Sensors. However, the system
still needs to be serviced as long as the SER-
VICE TPM SYSTEM message exists.
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, the TPM Telltale Light 
238

will turn on, and the EVIC will still display a
Low Pressure message and a “flashing”
pressure value in the graphic display. After
driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), theTPM Telltale
Light will flash on and off for 75 seconds
and then remain on, the EVIC will display a
“SERVICE TPM SYSTEM message and then
display dashes (- -) in place of the pressure
value. For each subsequent ignition switch
cycle, a chime will sound, the TPM Telltale
Light will flash on and off for 75 seconds
and then remain on, the EVIC will display a
 SERVICE TPM SYSTEM message and then
display dashes (- -) in place of the pressure
value. Once you repair or replace the origi-
nal road tire, and reinstall it on the vehicle in
place of the spare tire, the TPMS will update
automatically.
In addition, the graphic in the EVIC will display
a new pressure value instead of dashes (- -), as
long as no tire pressure is below the low-
pressure warning limit in any of the four active
road tires. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.TPMS DeactivationThe TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter
wheel and tire assemblies on your vehicle To
deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) Sensors. Then, drive the vehicle for
20 minutes above 24 km/h (15 mph). The TPMS
will chime, the TPM Telltale Light will flash on
and off for 75 seconds and then remain on and
the Electronic Vehicle Information Center
(EVIC) will display the “SERVICE TPM SYSTEM”
message and then display dashes (--) in place
of the pressure values. Beginning with the next
ignition switch cycle, the TPMS will no longer
chime or display the “SERVICE TPM SYSTEM”
message in the EVIC but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 20 minutes above 24 km/h
(15 mph). The TPMS will chime, the TPM Telltale Light
will flash on and off for 75 sec-
onds and then turn off, and the Electronic
Vehicle Information Center (EVIC) will display
the “SERVICE TPM SYSTEM” message as long
as no system fault exists. The EVIC will also
display pressure values in place of the dashes,
on the next ignition switch cycle the SERVICE
TPM SYSTEM message will no longer be dis-
played as long as no system fault exists.
General InformationTransmitter and receivers operate on a carrier
frequency of 433.92 MHz as required by EEC
regulations. These devices must be certified to
conform to specific regulations in each indi-
vidual country. Two sets of regulations are
involved: ETS (European Telecommunication
Standard) 300–220, which most countries use,
and German BZT federal regulation 225Z125,
which is based on ETC 300–220 but has addi-
tional unique requirements. Other defined re-
quirements are noted in ANNEX VI of COMMIS-
SION DIRECTIVE 95/56/EC. Operation is
subject to the following conditions:
• This device may not cause harmful interfer-
ence.
239

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.

The transfer case must be shifted into NEU-
TRAL (N) and the transmission must be placed
in PARK for recreational towing. The NEUTRAL
(N) selection button is adjacent to the transfer
case selector switch. Shifts into and out of
transfer case NEUTRAL (N) can take place with
the selector switch in any mode position.
CAUTION!
• Front or rear wheel lifts should not be used.
Internal damage to the transmission or
transfer case will occur if a front or rear
wheel lift is used when recreational towing.
• Tow only in a forward direction. Towing this
vehicle backwards can cause severe dam-
age to the transfer case.
• The transmission must be placed in PARK
for recreational towing.
(Continued)
CAUTION!(Continued)
• Before recreational towing, perform the
procedure outlined under “Shifting into
NEUTRAL (N)” to be certain that the trans-
fer case is fully in NEUTRAL (N). Other-
wise, internal damage will result.
• Failure to follow these procedures can
cause severe transmission and/or transfer
case damage.
• Do not use a bumper-mounted clamp-on
tow bar on your vehicle. The bumper face
bar will be damaged. Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in
the NEUTRAL (N) position without first fully
engaging the parking brake. The transfer case
NEUTRAL (N) position disengages both the
front and rear driveshafts from the powertrain
and will allow the vehicle to move, even if the
transmission is in PARK. The parking brake
should always be applied when the driver is
not in the vehicle.
Use the following procedure to prepare your
vehicle for recreational towing.
CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in NEU-
TRAL (N) before recreational towing to pre-
vent damage to internal parts.
1. Bring the vehicle to a complete stop and
shift the transmission to PARK.
