Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle has a
content theft-deterrent
alarm system.
To activate the content theft-deterrent system:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.
If the lock button on the remote keyless entry transmitter
is pressed, but a door is open, the doors will lock,
the lights may ash and the horn may sound. Close
the open door and the alarm system will arm.If a locked door is not opened using the remote keyless
entry transmitter, or by OnStar
®, the alarm will go off.
First, a pre-alarm will sound the horn at reduced
intensity for 10 seconds. Then, the front turn signal
lamps will ash for two minutes, and the horn will sound
for two minutes. The alarm will then turn off to save
battery power.
Starting the engine with the correct key will shut off the
pre-alarm or alarm at any time.
Remember, the theft-deterrent system will not activate
if you lock the doors with the key, the manual door lock,
or power door lock switch. The system can only be
activated using the remote keyless entry transmitter, or
by OnStar
®. SeeOnStar®System on page 2-48for
additional information. You should also remember that
you can start your vehicle with the correct key if the
alarm has been set off.
Here is how to avoid setting off the alarm by accident:
If you do not want to arm the theft-deterrent
system, the vehicle should be locked with the
manual door lock lever, the power door lock switch,
or the key, after the doors are closed.
If the content theft-deterrent system is armed,
unlock the doors by pressing the unlock button
on the remote keyless entry transmitter or by
OnStar
®. Unlocking a door any other way will
activate the alarm.
2-14

If you set off the alarm by accident, you can turn it off
by pressing unlock on the remote keyless entry
transmitter, starting the vehicle with the correct key, or
by having OnStar
®unlock the doors. The alarm will
not stop if you try to unlock a door any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Unlock the door with the manual door lock and
open the door. This should set off the pre-alarm.
Wait 10 seconds for the full alarm to activate.
3. To turn the alarm off, press the unlock button
on the remote keyless entry transmitter or start
the engine.
If the alarm does not sound when it should but the
lights ash, check to see if the horn works. The horn
fuse may be blown. To replace the fuse, seeFuses
and Circuit Breakers on page 5-102.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer/retailer for service.
Passlock®(U. S. Only)
Your vehicle has the Passlock®theft-deterrent system.
Passlock®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If an incorrect key is used or the
ignition lock cylinder is tampered with, the fuel system
is disabled and the vehicle will not start.
During normal operation, the security light will turn off
approximately ve seconds after the engine is started.
SeeSecurity Light on page 3-39.
If the engine stalls and the security light ashes, wait
about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release
the key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the engine
off. However, your Passlock
®system is not working
properly and must be serviced by your dealer/retailer.
Your vehicle is not protected by Passlock
®at this time.
See your dealer/retailer for service.
In an emergency, call the Roadside Assistance Center.
SeeRoadside Assistance Program on page 7-6.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
2-15

Automatic Transmission Operation
The automatic transmission has a shift lever on the
console.
It features an electronic shift position indicator within
the instrument cluster. This display must be powered
anytime the shift lever is capable of being moved out of
PARK (P). This means that if your key is turned off,
but not in LOCK, there will be a small current drain on
your battery which could discharge your battery over
a period of time. If you need to leave your key in
the ignition but not in LOCK for an extended period,
it is recommended that you disconnect the battery cable
from the battery to prevent discharging your battery.
There are several different positions for your shift lever.PARK (P):This position locks your rear wheels. It is
the best position to use when you start the engine
because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
SeeShifting Into PARK (P) (Automatic
Transmission) on page 2-33. If you are pulling a
trailer, seeTowing a Trailer on page 4-50.
Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.
You must fully apply your regular brakes rst and
then press the shift lever button before you can
shift from PARK (P) when the ignition key is in ON.
2-23

Transfer Case Buttons
The transfer case buttons are located to the right of the
instrument panel cluster. Use these switches to shift
into and out of the different Full-Time Four-Wheel
Drive modes.
You can choose between four modes:
4
m(Four-Wheel High):This setting is used for driving
in most street and highway situations. You can also
use this setting for light or variable off-road conditions.
N (NEUTRAL):Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 4-48orTowing
Your Vehicle on page 4-48for more information.Notice:Driving on pavement in Four-Wheel
High Lock or Four Wheel Low Lock for extended
periods may cause premature wear on your vehicle’s
powertrain and tires. Do not drive in Four-Wheel
High Lock or Four-Wheel Low Lock on pavement for
extended periods.
4
mQ(Four-Wheel-High Lock):Use this mode
when you need extra traction in most off-road situations
such as sand, mud, snow or level, rocky trails.
Notice:Operating your vehicle in
Four-Wheel-Low Lock above 30 mph (48 km/h) for
any extended period of time could cause damage
to the transfer case. Do not operate your vehicle
in Four-Wheel-Low Lock above 30 mph (48 km/h) for
extended periods.
4
nQ(Four-Wheel-Low Lock):This mode delivers
extra torque to all four wheels and is used for extreme
off-road conditions. You might choose 4-Wheel-Low
Lock if you are driving in off-road situations, such as,
deep sand, mud, or snow and climbing or descending
steep hills.
If the vehicle has a locking rear axle, when in this mode
you can also choose to lock the rear axle for additional
traction in extreme off-road situations. SeeLocking Rear
Axle on page 4-6.

Programming the Universal Home
Remote System
If you have questions or need 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 you begin. If you do not follow these actions,
the device will time out and you will have to repeat
the procedure.
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 ash, 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
1 to 3 inches (3 to 8 cm) 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 that you would
like to use 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 you to substitute Step 3 with the
procedure noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light on the Universal Home Remote
will ash slowly at rst and then rapidly after
Universal Home Remote successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.

Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let
go. The wipers will stop after one wipe. Hold the band
on mist longer, if more wipes are needed.
N(Delay):The wiper speed can be set for long
or short delays between wipes. This can be very useful
in light rain or snow. Turn the band to choose the
delay time. The closer to the top of the lever, the shorter
the delay.
6(Low Speed):For steady wiping at low speed,
turn the band away from you to the rst solid position
past the delay settings.
1(High Speed):For high-speed wiping, turn the
band to the second solid position past the delay settings.
9(Off):Move the band to off, to stop the wipers.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If your blades do
become worn or damaged, get new blades or blade
inserts.Windshield wipers work in all power modes, except
when set to LOCK. After the engine is turned off, wipers
will work in Retained Accessory Power (RAP) mode
until a door is opened. SeeRetained Accessory Power
(RAP) on page 2-20.
Windshield Washer
L(Washer Fluid):There is a paddle marked with the
windshield washer symbol at the top of the multifunction
lever. To spray washer uid on the windshield, push the
paddle. The wipers will clear the window and then either
stop or return to your preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
3-10

Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake or step on the clutch.
This, of course, disengages the cruise control. But you
do not need to reset it.
Once you are going about 25 mph (40 km/h) or more,
you can move the cruise control switch briey from on to
resume/accelerate.
The vehicle will go back to the chosen speed and
stays there.
If you hold the switch at resume/accelerate the vehicle
will keep going faster until you release the switch or
apply the brake. Do not hold the switch at resume/
accelerate, unless you want the vehicle to go faster.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You will now cruise at the higher speed.
If the accelerator pedal is held longer than
60 seconds, cruise control will turn off.
Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the
speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch briey to resume/accelerate. Each
time you do this, your vehicle goes about 1 mph
(1.6 km/h) faster.
3-13

Reducing Speed While Using Cruise
Control

Press and hold the set button until you reach the
desired lower speed, then release it.
To slow down in very small amounts, briey press
the set button. Each time you do this, you will go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle
slows down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control works on hills depends
upon your speed, load, and the steepness of the hills.
When going up steep hills, you might want to step on the
accelerator pedal to maintain the vehicle speed.When going downhill, you might have to brake or shift
to a lower gear to keep the vehicle speed down. Of
course, applying the brake turns off the cruise control.
Many drivers nd this to be too much trouble and do not
use cruise control on steep hills.
Ending Cruise Control
To turn off the cruise control, do one of the following:
Step lightly on the brake pedal.
Move the cruise control switch to off.
Lightly tap or press the clutch, if you have a manual
transmission.
Erasing Speed Memory
When you turn off the cruise control or the ignition, the
cruise control set speed memory is erased.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P) if you have 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 rst
sold in Canada, if parking lamps are manually turned
on, DRL will stay on.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
To turn off the DRL, seeExterior Lamps on page 3-15.Vehicles rst sold in Canada cannot turn off DRL unless
certain conditions are met. SeeExterior Lamps on
page 3-15.
Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system will turn on after the transmission has been
shifted from PARK (P) to DRIVE (D). The headlamps,
taillamps, sidemarker, parking lamps, roof marker lamps,
and the instrument panel lights will turn on at normal
brightness. The radio lights will become more dim when
the headlights are off compared to when the headlights
are on.
Your vehicle has a light sensor located on the top of the
instrument panel. Be sure it is not covered, or the
system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. 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.
