2008 JEEP WRANGLER light

Daytime Brightness Feature
Certain instrument panel components (odometer, radio
display) can be illuminated at full brightness during the
daytime. This can be helpful when driving with your
headlights on during the daytime, such as in a parade or
a funeral procession. To activate this feature, rotate the
left stalk one detent lower than the dome light.
Multifunction Control Lever
The multifunction control lever controls the operation of
the parking lights, headlights, headlight beam selection,
passing light, fog lights, instrument panel light dimming,
and turn signals. The lever is located on the left side of
the steering column.
Parking Lights, Instrument Panel Lights, and
Headlights

NOTE:Lens fogging can occur under certain atmo-
spheric conditions. This will usually clear as atmospheric
conditions change to allow the condensation to change
back into a vapor. Turning the lamps on will usually
accelerate the clearing process. To change the brightness of the instrument panel lights,
rotate the center portion of the multifunction control
lever up or down.
NOTE:
If the driver’s door is left open, and the head-
lights or parking lights are left on, the High Beam
Indicator Light will remain illuminated and a chime will
sound.
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.
Headlight Dimmer Switch
Push the multifunction control lever away from you to
switch the headlights to high beam. Pull the lever to-
wards you to switch the headlights back to low beam.

Passing Light
You can signal another vehicle with your headlights by
lightly pulling the multifunction 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.
Front Fog Lights — If Equipped
The front fog light switch is located on the multi-
function control lever. To activate the front fog
lights, turn on the parking or low beam headlights
and pull out the end of the lever.
NOTE: The fog lights will only operate with the parking
lights or the headlights on low beam. Selecting high
beam headlights will turn off the fog lights.
Turn Signals
Move the multifunction control lever up or down, and
the arrows on each side of the instrument cluster flash, to
show proper operation of the front and rear turn signal
lights. You can signal a lane change by moving the lever
partially up or down without moving beyond the detent.
If either light has a very fast flash rate, check for a
defective outside light bulb. If an indicator fails to light
when the lever is moved, it would suggest that the fuse
or indicator is defective or there may be a circuit failure.
NOTE: A tone will chime if the turn signals are left on
for more than 1 mi (2 km).
Daytime Running Lights — If Equipped
The headlights come on at a low intensity level after the
vehicle has been driven approximately 3 ft (1 m). They
will turn off when the vehicle is turned off or when the
headlights are switched on.

WARNING!
Tilting the steering column while the vehicle is
moving is dangerous. Without a stable steering col-
umn, you could lose control of the vehicle and have
an accident. Adjust the column only while the ve-
hicle is stopped. Be sure it is locked before driving.
ELECTRONIC SPEED CONTROL — IF EQUIPPED
When engaged, this device takes over the accelerator
operation at speeds greater than 35 mph (56 km/h). The
speed control lever is located on the right side of the
steering wheel.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in
the instrument cluster will illuminate. To turn the system
OFF, push the ON/OFF button a second time. The Cruise
Indicator Light will turn off. The system should be
turned OFF when not in use.
Speed Control Switches
102 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Tapping RESUME ACCEL once will result in a 1 mph (1.6
km/h) speed increase. Each time the lever is tapped,
speed increases so that tapping the lever three times will
increase speed by 3 mph (4.8 km/h), etc.
To decrease speed while speed control is ON, push down
and hold SET DECEL. Release the lever when the desired
speed is reached, and the new speed will be set.
Tapping the SET DECEL button once will result in a 1
mph (1.6 km/h) speed decrease. Each time the button is
tapped, speed decreases.
NOTE:The Electronic Speed Control System has been
designed to shut down if multiple speed control switch
functions are operated simultaneously in order to ensure
proper operation. If this occurs, the system can be
reactivated by pushing the speed control switch ON/
OFF button and re-setting the desired vehicle SET speed.Manual Transmission
Depressing the clutch pedal will disengage the speed
control. A slight increase in engine RPM before the speed
control disengages is normal.
Vehicles equipped with manual transmissions may need
to be shifted into a lower gear to climb hills without
speed loss.
WARNING!
Speed Control can be dangerous where the system
can’t maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control. An accident could be the result. Do not use
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered, or slippery.

To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
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 and/or more
frequent downshifts (auto transmission only) 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.
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 “Anti-Lock Brake System” in Section 5 of this
manual for more information about ABS.

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.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The ESP/TCS Indicator Light (located in the instrument
cluster), starts to flash as soon as the tires lose traction
and the ESP system becomes active. The ESP/TCS Indi-
cator Light also flashes when TCS is active. If the
ESP/TCS Indicator Light begins to flash during accelera-
tion, 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 three available operating modes in
4H range. The system has one operating mode in 4L
range. 2WD vehicles and 4WD vehicles in 2H range have
two operating modes.
4H Range (4WD Models) or 2WD Models
On
This is the normal operating mode for ESP in 4H and
2WD vehicles. Whenever the vehicle is started or the
transfer case (if equipped) is shifted from 4L range or
NEUTRAL back to 4H range, the ESP system will be in
this mode. This mode should be used for most all driving
situations. ESP should only be turned to “Partial Off” or
“Full Off” for specific reasons as noted below.
Partial Off
This mode is entered by momentarily depressing the ESP
OFF switch. When in Partial Offmode, the TCS portion
of ESP has been disabled and the ESP/TCS Indicator
Light will 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, or gravel conditions
and more wheel spin than ESP would normally allow is
