2008 JEEP GRAND CHEROKEE warning

section. For information on the rear wiper and washer,
refer to ªRear Window Featuresº in this section.
NOTE:Always remove any build-up of snow that
prevents the windshield wiper blades from returning to
the OFF position. If the windshield wiper switch isturned off and the blades cannot return to the OFF
position, damage to the wiper motor may occur.
To use the washer, pull the lever toward you and hold
while spray is desired. If the lever is pulled while in the
delay range, the wiper will operate for several seconds
after the lever is released, and then resume the intermit-
tent interval previously selected.
If the lever is pulled while in the OFF position, the wipers
will operate for several wipe cycles, then turn off.
WARNING!
Sudden loss of visibility through the windshield
could lead to an accident. You might not see other
vehicles or other obstacles. To avoid sudden icing of
the windshield during freezing weather, warm the
windshield with the defroster before and during
windshield washer use.

TILT/TELESCOPING STEERING COLUMN
This feature allows you to tilt the steering column
upward or downward. It also allows you to lengthen or
shorten the steering column. The tilt/telescoping control
handle is located below the steering wheel at the end of
the steering column.To unlock the steering column, push the control handle
downward (toward the floor). To tilt the steering column,
move the steering wheel upward or downward as de-
sired. To lengthen or shorten the steering column, pull
the steering wheel outward or push it inward as desired.
To lock the steering column in position, push the control
handle upward until fully engaged.
WARNING!
Do not adjust the steering wheel while driving. The
telescoping adjustment must be locked while driv-
ing. Adjusting the steering wheel while driving or
driving without the telescoping adjustment locked
could cause the driver to lose control of the vehicle.

OFF, push the ON/OFF button a second time. The
CRUISE indicator will turn off. The system should be
turned OFF when not in use.
WARNING!
Leaving the Speed Control system on when not in
use is dangerous. You could accidentally set the
system or cause it to go faster than you want. You
could lose control and have an accident. Always
leave the system OFF when you are not using it.
To Set At A Desired Speed
When the vehicle has reached the desired speed, press
down on the lever and release. Release the accelerator
and the vehicle will operate at the selected speed.
NOTE:The vehicle should be traveling at a steady
speed and on level ground before pressing the SET lever.
To Deactivate
A soft tap on the brake pedal, pulling the speed control
lever towards you ªCANCELº, or normal brake or clutch
pressure while slowing the vehicle will deactivate speed
control without erasing the set speed memory. Pressing
the ON/OFF button or turning off the ignition switch
erases the set speed memory.

WARNING!
ABS (Anti-Lock Brake System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ABS cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ABS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user's safety or the safety of others.
TCS (Traction Control System)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in
either the ªPartial Offº or ªFull Offº modes. Refer to ªESP
(Electronic Stability Program)º in this section for more
information.

BAS (Brake Assist System)
The BAS is designed to optimize the vehicle's braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must applycontinuousbrak-
ing pressure during the stopping sequence (do not
ªpumpº 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!
BAS (Brake Assist System) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor can
it increase the traction afforded by prevailing road
conditions. BAS cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. Only a
safe, attentive, and skillful driver can prevent acci-
dents. 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.

ERM (Electronic Roll Mitigation)
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 vehicles 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.NOTE:Anytime the ESP system is in the ªFull Offº
mode, ERM is disabled. Refer to ESP (Electronic Stability
Program) for a complete explanation of the available ESP
modes.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user's safety or the safety of others.

WARNING!
ESP (Electronic Stability Program) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESP cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESP-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user's safety or the safety of others.
The ESP system has 3 available operating modes in 4WD
High Range, 2 available operating modes on 2WD ve-
hicles, and 1 operating mode in 4WD Low Range.
High Range (4WD Models) or 2WD Models
On
This is the normal operating mode for ESP in 4WD high
range and in 2WD vehicles. 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
ESP system will be in this ªOnº mode. This mode should
be used for most driving situations. ESP should only be
turned to ªPartial Offº or ªFull Offº mode for specific
reasons as noted below.
Partial Off
This mode is entered by momentarily depressing the
9ESP OFFº switch. When in9Partial Off9mode, the TCS
portion of ESP, except for the ªlimited slipº feature
described in the TCS section, has been disabled and the
9ESP/TCS Indicator Light9will be illuminated. All other
stability features of ESP function normally. This mode is
intended to be used if the vehicle is in deep snow, sand,

In this mode, ESP and TCS, except for the ªlimited slipº
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 40 mph (64 km/h). At 40
mph (64 km/h) the system returns to ªPartial Offº mode,
described above. When the vehicle speed drops below 35
mph (56 km/h) the ESP system shuts off. ESP is deacti-
vated at low vehicle speeds so that it will not interfere
with off-road driving but ESP function returns to provide
the stability feature at speeds above 40 mph (64 km/h).
The ªESP/TCS Indicator Lightº will always be illumi-
nated when ESP is off. To turn ESP on again, momen-
tarily depress the ªESP OFFº switch. This will restore the
normal ªESP Onº mode of operation.
NOTE:The ªESP OFFº message will display and the
audible chime will sound when the gear selector is
placed into the ªPº (Park) position from any other
position, and then moved out of the ªPº (Park) position.
This will occur even if the message was previously
cleared.WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The ªFull Offº ESP mode is intended for
off-road use only.
4WD Low Range
Full Off
This is the normal operating mode for ESP 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 ESP system
will be in this ªFull Offº mode. In 4WD low range, ESP
and TCS, except for the ªlimited slipº feature described
in the TCS section, are turned off until the vehicle reaches
