If the light comes on while driving,
pull off the road and stop. The brake
pedal might be harder to push, or it
might go closer to the floor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing the Vehicle
on
page 10‑90.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light will then go off.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes. If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light
on page 5‑14.
For vehicles with a Driver
Information Center (DIC), see
Brake System Messages
on
page 5‑22for more information.
Up-Shift Light
The vehicle may have an up-shift
light.
When this light comes on, shift to
the next higher gear if weather,
road, and traffic conditions allow.

Programming the Universal
Home Remote System
For questions or help programming
the Universal Home Remote
System, call 1‐800‐355‐3515
or go to www.homelink.com.
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.To program up to three devices:
1. From inside the vehicle, press
and hold down the two outside
buttons at the same time,
releasing only when the
Universal Home Remote
indicator light begins to flash,
after 20 seconds. This step will
erase the factory settings or all
previously programmed buttons.
Do not hold down the buttons for
longer than 30 seconds and do
not repeat this step to program
the remaining two Universal
Home Remote buttons. 2. Hold the end of your hand-held
transmitter about 3 to 8 cm
(1 to 3 inches) away from the
Universal Home Remote buttons
while keeping the indicator
light in view. The hand-held
transmitter was supplied by the
manufacturer of your garage
door opener receiver (motor
head unit).
3. At the same time, press and hold both the Universal Home
Remote button to be used to
control the garage door and the
hand-held transmitter button.
Do not release the Universal
Home Remote button or the
hand-held transmitter button until
Step 4 has been completed.
Some entry gates and garage
door openers may require
substitution of Step 3 with the
procedure noted in “Gate
Operator and Canadian
Programming” later in this
section.

8. Immediately return to thevehicle. Firmly press and hold
the Universal Home Remote
button, selected in Step 3 to
control the garage door, for
two seconds, and then release
it. If the garage door does not
move, press and hold the
same button a second time for
two seconds, and then release
it. Again, if the door does not
move, press and hold the
same button a third time for
two seconds, and then release.
The Universal Home Remote
should now activate the
garage door.
To program the remaining
two Universal Home Remote
buttons, begin with Step 2 of
“Programming the Universal Home
Remote System.” Do not repeat
Step 1, as this will erase all
previous programming from the
Universal Home Remote buttons.Gate Operator and Canadian
Programming
If you have questions or need
help programming the Universal
Home Remote System, call
1-800-355-3515 or go to
www.homelink.com.
Canadian radio-frequency laws
require transmitter signals to time
out or quit after several seconds
of transmission. This may not be
long enough for Universal Home
Remote to pick up the signal during
programming. Similarly, some U.S.
gate operators are manufactured to
time out in the same manner. If you live in Canada, or you are
having difficulty programming a gate
operator or garage door opener by
using the
“Programming Universal
Home Remote” procedures,
regardless of where you live,
replace Step 3 under “Programming
Universal Home Remote” with the
following:
Continue to press and hold the
Universal Home Remote button
while you press and release
every two seconds (cycle) the
hand-held transmitter button until
the frequency signal has been
successfully accepted by the
Universal Home Remote. The
Universal Home Remote indicator
light will flash slowly at first and then
rapidly. Proceed with Step 4 under
“Programming Universal Home
Remote” to complete the training
procedure.

6-2 Lighting
9(Off):Turns all exterior lamps
and the Daytime Running Lamps
(DRL) off. This is a momentary
control that returns to AUTO when
released. The DRL does not turn off
on vehicles first sold in Canada,
unless the following conditions
are met:
.The vehicle has an automatic
transmission.
.The gear position is in P (Park).
.The headlamp switch is turned
to
9.
AUTO (Automatic): Turns the
headlamps on and off automatically,
together with the following:
.Sidemarker Lamps
.Taillamps
.Parking Lamps
.Instrument Panel Lights
Due to the momentary control, the
automatic headlamps may be
disabled even if the control is in the
AUTO position. To enable automatic lighting, do any
of the following:
.Turn the headlamp control from
AUTO to off and release the
control. It returns to the AUTO
position by itself.
.Turn the headlamp control from
the parking lamp or headlamp
position to AUTO.
To disable automatic lighting, do any
of the following:
.Turn the headlamp control from
AUTO to off and release the
control. It returns back to the
AUTO position by itself.
.Turn the headlamp control from
AUTO to the parking lamp or
headlamp position.
See Automatic Headlamp System
on page 6‑4for more information.
Vehicles first sold in Canada with an
automatic transmission cannot turn
off automatic headlamps unless the
gear position is in P (Park) and the
headlamp control is turned to
O. Vehicles first sold in Canada with a
manual transmission can turn off
the automatic headlamps with the
headlamp control; however, the
parking lamps will remain on.
;
(Parking Lamps): Turns on the
parking lamps, together with the
following:
.Sidemarker Lamps
.Taillamps
.License Plate Lamps
.Instrument Panel Lights
2 (Headlamps): Turns on the
headlamps together with the
previously listed lamps and lights.
The headlamps can be switched
from low to high beam by pushing
the turn signal/lane change lever
toward the instrument panel.

6-4 Lighting
The DRL system comes on when
the following conditions are met:
.The ignition is on.
.The exterior lamps control is
in AUTO.
.The transmission is not in
P (Park), if the vehicle has an
automatic transmission.
.The light sensor determines it is
daytime.
When the DRL are on, no other
lamps are on. The instrument panel
will not be lit up either. For vehicles
first sold in Canada, if parking lamps
are manually turned on, DRL will
stay on.
When it begins to get dark, the
automatic headlamp system
changes from DRL to the
headlamps.
The regular headlamp system
should be turned on when needed.
To turn off the DRL, see Exterior
Lamp Controls
on page 6‑1. Vehicles first sold in Canada
cannot turn off DRL unless certain
conditions are met. See
Exterior
Lamp Controls on page 6‑1.
Automatic Headlamp
System
When it is dark enough outside, the
automatic headlamp system turns
on after the transmission has been
shifted from P (Park) to D (Drive).
The headlamps, taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights turn on at normal
brightness. The radio lights will
become dimmer when the
headlights are off compared to
when the headlights are on.
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor,
or the system will be on whenever
the ignition is on. The system can turn on the
headlamps when driving in a
parking garage, through a tunnel or
when there is overcast weather.
This is normal.
There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system will only be
affected when the light sensor
detects a change in lighting lasting
longer than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes about one minute for the
automatic headlamp system to
change to DRL if it is light outside.

Brake and Accelerator
Operation Techniques for
Off-Road Driving
For logs, walls, rocks, severe
ditches, hills, sand, etc.
1. Bring the vehicle to a completestop. Do not rev the engine.
2. Select the proper transmission and transfer case gear
range; usually 1 (First) gear,
Four‐Wheel‐Low Lock for
such obstacles.
3. If wheel spin is experienced, maintain steady throttle, with
your foot off the brake pedal,
to allow the Traction Control
System (TCS) to control the
wheel spin. TCS might not
operate if the brakes are
applied. 4. If wheel spin cannot be
controlled by the TCS system,
fully press the brake pedal with
your left foot so all wheel spin is
stopped.
5. Back away from the obstacle so that a new approach can be
tried.
6. As the first wheel crosses the obstacle, be prepared to
alternate the brake and
accelerator pedal to maintain
control and avoid tire drop-off
from obstacles. Repeat this
process for the other wheels.
