2010 JEEP GRAND CHEROKEE snow chains

High Range (Four-Wheel Drive Models)
On
This is the normal operating mode for ESC in
4WD HIGH range. Whenever the vehicle is
started or the transfer case (if equipped) is
shifted from 4WD LOW range or NEUTRAL
back to 4WD HIGH range, the ESC system will
be in this “On” mode. This mode should be
used for most driving situations. ESC should
only be turned to “Partial Off” mode for specific
reasons as noted below.
Partial Off
This mode is entered by momentarily pressing
the “ESC OFF” switch. When in “Partial Off”
mode, the TCS portion of ESC, except for the
BLD feature described in the TCS section, has
been disabled and the “ESC Off Indicator
Light” will be illuminated. All other stability
features of ESC function normally. This mode is
intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more
wheel spin than ESC would normally allow is
required to gain traction. To turn ESC on again,
momentarily press the “ESC OFF” switch. This
will restore the normal “ESC On” mode of
operation.NOTE:
To improve the vehicle’s traction when driv-
ing with snow chains, or starting off in deep
snow, sand, or gravel, it may be desirable to
switch to the “Partial Off” mode by pressing
the “ESC OFF” switch. Once the situation
requiring ESC to be switched to the “Partial
Off” mode is overcome, turn ESC back on by
momentarily pressing the “ESC OFF”
switch. This may be done while the vehicle
is in motion.4WD Low Range
Partial Off
This is the normal operating mode for ESC in
4WD LOW range. Whenever the vehicle is
started in 4WD LOW range, or the transfer case
(if equipped) is shifted from 4WD HIGH range
or NEUTRAL to 4WD LOW range, the ESC
system will be in the “Partial Off” mode.
Trailer Sway Control (TSC)TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and
apply the brake of the appropriate wheel(s) to
counteract the sway of the trailer. TSC will
become active automatically once an exces-
sively swaying trailer is recognized. No driver
action is required. Note that TSC cannot stop all
trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Tow-
ing” in “Starting and Operating” for further
information. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will
flash, the engine power may be reduced and
you may feel the brakes being applied toESC OFF Switch

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

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
