2008 JEEP GRAND CHEROKEE light

This system performs two functions. With the engine
running and the multi-function control lever in the A
(Auto) position, the headlights will turn on and off based
on the surrounding light levels.
Headlights On Automatically With Wipers
If your vehicle is equipped with Automatic Headlights it
also has this customer programmable feature. When your
headlights are in the automatic mode, and the engine is
running, they will automatically turn on when the wiper
system is on.
If your vehicle is equipped with a ªRain Sensitive Wiper
System,º and it is activated, the headlights will automati-
cally turn on after the wipers complete five wipe cycles
within approximately 1 minute, and they will turn off
approximately four minutes after the wipers completely
stop. Refer to ªWindshield Wipers and Washersº in this
section for more information.NOTE:When your headlights come on during the
daytime, the instrument panel lights will automatically
dim to the lower nighttime intensity. Refer to ªInstru-
ment Panel and Interior Lightsº below for setting the
instrument panel lights to full daytime intensity.SmartBeams Ð If Equipped
The SmartBeam system provides increased forward light-
ing at night by automating high beam control through
the use of a digital camera mounted on the inside
rearview mirror. This camera detects vehicle specific light
and automatically switches from high beams to low
beams until the approaching vehicle is out of view.
NOTE:If the windshield or SmartBeam mirror is re-
placed, the SmartBeam mirror must be re-aimed to
ensure proper performance. See your local authorized
dealer.

headlights to remain on longer (closer to the vehicle).
Also, dirt, film, and other obstructions (sticker, toll box,
etc.) on the windshield or camera lens will cause the
system to function improperly.
Instrument Panel and Interior Lights
When the multi-function control lever is in the parklight,
headlight, or A (Auto) position (if equipped), rotating the
center portion of the lever up and down will increase and
decrease the brightness (dimmer control) of the instru-
ment panel lights. Full daytime brightness on all elec-
tronic displays (odometer, overhead console, radio, and
Automatic Climate Control (if equipped) is obtained by
rotating the center portion of the control to the first
detent above the dimmer range. Rotating the control to
the second detent above the dimmer range turns the
interior lights on. Rotating the control to the ªOffº
(extreme bottom) position disables all the interior lights,

even when the doors and liftgate are open. While in the
ªOffº position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights Ð If Equipped
The high beam headlights come on at a low intensity
level whenever the engine is running, and the transmis-
sion in not in the P (Park) position. The lights remain on
until the ignition switch is turned OFF or the parking
brake is engaged. The headlight switch must be used for
normal night time driving.
Automatic Headlight Leveling Ð HID Headlights
Only
This feature prevents the headlights from interfering
with the vision of oncoming drivers. Headlight leveling
automatically adjusts the height of the headlight beam in
reaction to changes in vehicle pitch.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned OFF, a chime will sound when the driver's door
is opened.
Fog Lights Ð If Equipped
The fog light switch is located in the multi-
function control lever. To activate the fog lights,
turn on the park/turn lights, low beam headlights,
or ªAutoº headlights and pull out the end of the multi-
function control lever. A light in the instrument cluster
shows when the fog lights are on.
NOTE:Turning on the high beam headlights turns off
the fog lights.
A front fog light is a lighting device providing illumina-
tion forward of the vehicle under conditions of fog, rain,
snow, or dust. Principally, the front fog light supplements
the lower beam of a standard headlight system.

wards you to switch the headlights back to low beam.
Passing Light
You can signal another vehicle with your headlights by
lightly pulling the multi-function control lever toward
the steering wheel. This will cause the headlights to turn
on at high beam and remain on until the lever is released.
Headlight Time Delay
There is also a feature that delays turning off the vehicle
lights for 30, 60, or 90 seconds after the ignition switch is
turned OFF. To activate the headlight delay, the multi-
function control lever must be rotated to the ªOffº
position after the ignition switch is turned OFF. Only the
headlights will illuminate during this time. Refer to

Using Speed Control On Hills
The automatic transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:The speed control system maintains speed up
and down hills. A slight speed change on moderate hills
is normal.
On steep hills a greater speed loss or gain may occur so
it may be preferable to drive without speed control.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes ABS (Anti-Lock Brake
System), TCS (Traction Control System), BAS (Brake
Assist System), ERM (Electronic Roll Mitigation), and
ESP (Electronic Stability Program). All five of these
systems work together to enhance vehicle stability and
control in various driving conditions.Also, your vehicle is equipped with TSC (Trailer Sway
Control) and, if it has 4WD with the NV245 two-speed
transfer case, HSA (Hill Start Assist) and HDC (Hill
Descent Control).
ABS (Anti-Lock Brake System)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to ªAnti-Lock Brake Systemº in Section 5 of this
manual for more information about ABS.
138 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

ESP (Electronic Stability Program)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition. En-
gine 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.

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,
