2010 JEEP GRAND CHEROKEE change wheel

Lane Change Assist
Tap the lever up or down once, without moving beyond
the detent, and the turn signal (right or left) will flash
three times then automatically turn off.
High/Low Beam Switch
Push the multifunction lever away from you to switch
the headlights to high beam. Pull the multifunction lever
toward you to switch the headlights back to low beam.
Flash-to-Pass
You can signal another vehicle by lightly pulling the
multifunction lever toward the steering wheel. This will
turn on the high beam headlights until the lever is
released.
Headlight Time Delay
This feature delays turning off the headlights for 30, 60 or
90 seconds after the ignition switch is turned OFF. To
activate the headlight delay, the multifunction lever must
be rotated to the “Off” position after the ignition switchis turned to LOCK/ACC. Only the headlights will illu-
minate during this time. Refer to “Electronic Vehicle
Information Center (EVIC)/Customer-Programmable
Features” in “Understanding Your Instrument Panel” for
further information.
Interior Lights
The interior lighting consists of courtesy lights (below the
instrument panel), an overhead console light (which
contains both driver and passenger reading lights), read-
ing lights (located above the rear doors), and a rear cargo
light. Opening a door, pressing the UNLOCK button on
the Remote Keyless Entry (RKE) transmitter or turning
the center of the multifunction lever to the extreme up
position, will activate all interior courtesy lights.
Front Map/Reading Lights
These lights are mounted in the overhead console. Each
light can be turned on by pressing the recessed area of the
lens. To turn these lights off, press the recessed area of the

entering. Proceed with caution and maintain a steady
controlled speed less than 5 mph (8 km/h) in deep water
to minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm
run-off), avoid crossing until the water level recedes
and/or the flow rate is reduced. If you must cross
flowing water avoid depths in excess of 9 in (23 cm). The
flowing water can erode the streambed, causing your
vehicle to sink into deeper water. Determine exit point(s)
that are downstream of your entry point to allow for
drifting.
Standing Water
Avoid driving in standing water deeper than 20 in
(51 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed in 20 in (51 cm) of water is
less than 5 mph (8 km/h).Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to pre-
vent component damage.
Driving in Snow, Mud and Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary.
Refer to “Four-Wheel Drive Operation” in “Starting and
Operating” for further information. Do not shift to a
lower gear than necessary to maintain forward motion.
Over-revving the engine can spin the wheels and traction
will be lost.

benefit of the system, you must applycontinuousbrak-
ing pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
The BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
BAS cannot prevent accidents, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the safety
of others.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicle speed
are sufficient to potentially cause wheel lift, it then
applies the brake of the appropriate wheel and may also
reduce engine power to lessen the chance that wheel lift
will occur. ERM will only intervene during very severe or
evasive driving maneuvers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It cannot
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.
272 STARTING AND OPERATING

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
an accident 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 an accident.(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 CHAINS
Certain models have sufficient tire-to-body clearance to
allow use of tire chains.Install chains on rear tires only.
Follow these recommendations to guard against damage
and excessive tire and chain wear:
302 STARTING AND OPERATING

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. 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 regularly
check the tire pressure in all of your tires, and to maintain
the proper pressure.
The TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light A tire pressure monitoring sensor is located in the spare
wheel, if the vehicle is equipped with a matching full-size
spare wheel and tire assembly. The matching full-size
spare tire can be used in place of any of the four road
tires. A low spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate, a warning mes-
sage 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 instru-
ment cluster for 60 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 Monitor-
ing Telltale Light will extinguish, once the updated tire

Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
SNOW PLOW
Snow plows, winches, and other aftermarket equipment
should notbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.
WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing – Two-Wheel Drive Models
Recreational towing is allowed ONLY if the driveshaft
is removed. Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
