2008 JEEP GRAND CHEROKEE steering

²Low Ambient TemperatureÐ When the ignition is
first turned ON, the rain sensing system will not
operate until the wiper switch is moved, vehicle speed
is greater than 0 mph (0 km/h), or the outside tem-
perature is greater than 32ÉF (0ÉC).
²Transmission in N (Neutral) PositionÐ When the
ignition is ON, and the transmission is in the N
(Neutral) position, the rain sensing system will not
operate until the wiper switch is moved, vehicle speed
is greater than 5 mph (8 km/h), or the shift lever is
moved out of the N (Neutral) position.
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.
ADJUSTABLE PEDALS Ð IF EQUIPPED
This feature allows both the brake and accelerator pedals
to move toward the driver to provide improved position
with the steering wheel. The adjustable pedal system is
designed to allow a greater range of driver comfort for
steering wheel tilt and seat position. The position of the
brake and accelerator pedals can be adjusted without
compromising safety or comfort in actuating the pedals.Press the bottom of the switch to move the pedals
rearward (toward the driver).
Press the top of the switch to move the pedals forward
(away from the driver).
²The pedals can be adjusted with the ignition OFF.

²The pedals can be adjusted while driving.
²The pedalscannotbe adjusted when the vehicle is in R
(Reverse) or when the Speed Control is ON. A message
will be displayed in the Electronic Vehicle Information
Center (EVIC) if the pedals are attempted to be ad-
justed when the system is locked out (ªAdjustable
Pedal Disabled Ð Cruise Control Engagedº or ªAd-
justable Pedal Disabled Ð Vehicle In Reverseº). Refer
to Electronic Vehicle Information Center (EVIC) in
Section 4 for more information.
CAUTION!
Do not place any article under the adjustable pedal's
or impede its ability to move as it may cause damage
to the pedal controls. Pedal travel may become lim-
ited if movement is stopped by an obstruction in the
adjustable pedal's path.
ELECTRONIC SPEED CONTROL Ð IF EQUIPPED
When engaged, this device takes over accelerator opera-
tions at speeds greater than 25 mph (40 km/h).
Electronic Speed Control Operation
The speed control lever is located on the right side of the
steering wheel.

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 appropriate brake 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.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.

ESP (Electronic Stability Program)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
²Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The9ESP/TCS Indicator Light9located in the instrument
cluster, starts to flash as soon as the tires lose traction and
the ESP system becomes active. The9ESP/TCS Indicator
Light9also flashes when TCS is active. If the9ESP/TCS
Indicator Light9begins to flash during acceleration, ease
up on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to the
prevailing road conditions.

2. Pull up on loop(s) and twist 90 degrees, so they are
parallel to the slotted hole in tray.
3. Lift tray over loop(s), and reposition tray.
4. Pull up on loop(s) and twist 90 degrees, so they are

REAR WINDOW FEATURES
Rear Window Wiper/Washer Ð If Equipped
A switch on the right side of the steering column controls
operation of the rear wiper/washer function. Rotating
the switch up to the DEL (Delay) position or the ON
position will activate the wiper. Rotating the switch all
the way down will turn on the wash function. The washpump will continue to operate as long as the button is
pressed. Upon release, the wipers will cycle three times
before returning to the set position.
If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the ªParkº
position.Windshield Wiper/Washer Switch

Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:The radio, steering wheel radio controls (if
equipped), and 6 disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.
