Shifting Out of Four-Wheel Low Lock
To shift from Four-Wheel-Low Lock to Four-Wheel High
or Four-Wheel-High Lock, your vehicle must be
stopped or moving less than 3 mph (5 km/h) with the
transmission in NEUTRAL (N) and the ignition
in RUN. The preferred method for shifting out of
Four-Wheel-Low Lock is to have your vehicle moving
1 to 2 mph (1.6 to 3.2 km/h). Turn the dial to the
Four-Wheel High or Four-Wheel-High Lock position.
You must wait for the Four-Wheel High or
Four-Wheel-High Lock indicator light to stop ashing
and remain lit before shifting your transmission into gear.
It is normal for your vehicle to have engagement
noise and bump when shifting between Four-Wheel Low
and Four-Wheel High or Four-Wheel-High Lock ranges
or from NEUTRAL with the engine running.
If the Four-Wheel High or Four-Wheel-High Lock position
is selected when your vehicle is in gear and/or moving,
the Four-Wheel High or Four-Wheel-High Lock indicator
light will ash for 30 seconds but will not complete the
shift unless your vehicle is moving less than 3 mph
(5 km/h) and the transmission is in NEUTRAL (N).
Notice:Shifting the transmission into gear before
the indicator light stops ashing could cause
damage to the transfer case. Always wait until the
indicator light stops ashing before putting the
transmission back in gear.
Shifting into NEUTRAL
To shift the transfer case to NEUTRAL do the following:
1. Make sure the vehicle is parked so that it will not roll.
2. Set the parking brake and apply the regular brake
pedal. SeeParking Brake on page 2-40
3. Start the vehicle or turn the ignition to ON/RUN.
4. Put the transmission in NEUTRAL (N).
5. Shift the transfer case to Two-Wheel Drive High.
6. Turn the transfer case dial clockwise to NEUTRAL
position. The transfer case will not shift to NEUTRAL
unless this position is held for 10 seconds.
The NEUTRAL light will come on and then the dial
can be slowly released. The dial will be in the
Four-Wheel Low Lock position but the transfer case
will be in NEUTRAL with the NEUTRAL light on.
7. If the engine is running, make sure that the transfer
case is in NEUTRAL (N) by shifting the transmission
to REVERSE (R) for one second, then shift the
transmission to DRIVE (D) for one second.
8. Turn the ignition to ACC/ACCESSORY, which will
turn the engine off.
9. Place the transmission shift lever in PARK (P).
10. Release the parking brake prior to moving
the vehicle.
11. Turn the ignition to LOCK/OFF.

Four-Wheel High Lock or Four-Wheel Low Lock.
After the transfer case has shifted out of NEUTRAL
the NEUTRAL light will go out.
4. Release the parking brake prior to moving the
vehicle.
Notice:Shifting the transmission into gear before
the requested mode indicator light has stopped
ashing could damage the transfer case. To help
avoid damaging your vehicle, always wait for the
mode indicator lights to stop ashing before shifting
the transmission into gear.
5. Start the engine and shift the transmission to the
desired position.
Parking Brake
To set the parking brake, hold the regular brake pedal
down with your right foot. Push down the parking
brake pedal with your left foot.

the warning light will ash
when the parking brake
is applied and the vehicle
is moving at least 3 mph
(5 km/h) for at least
three seconds.
To release the parking brake, hold the regular brake
pedal down. Pull the bottom edge of the lever, located
above the parking brake pedal, with the parking
brake symbol, to release the parking brake.
If the ignition is on when the parking brake is released,
the brake system warning light will go off.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.

{CAUTION:
Full-time four-wheel drive vehicles with the
transfer case in NEUTRAL will allow the
vehicle to roll, even if the shift lever is in
PARK (P). So, be sure the transfer case is in a
drive gear — not in NEUTRAL. Always set the
parking brake.
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into PARK (P) on page 2-41.

Object Detection Systems
Rear Vision Camera
Your vehicle may be equipped with a rear vision camera
system. Read this entire section before using the
camera system.
The rear vision camera system is designed to help
the driver when backing up by displaying a view of the
area behind the vehicle. When the driver shifts the
vehicle into REVERSE (R), the video screen will
automatically slide out from the rear view mirror.
Once the driver shifts out of REVERSE (R), the video
screen will slide back into the rear view mirror after
a delay.
If your vehicle does not have a rearview mirror slide-out
video screen, your vehicle may have a navigation
radio system. See the Navigation System manual for
more information on the rear vision camera display
video screen.

Notice:The spare tire extends farther away from
rear of the vehicle than the trailer hitch shown
on rear vision camera display. Your spare tire could
hit an object even though there appears to be
enough distance on the display between the trailer
hitch and objects behind you causing vehicle or
property damage. Do not use this system to judge
the distance between the spare tire and objects
behind you.
When the System Does Not Seem To
Work Properly
The rear vision camera system may not work properly
or display a clear image in the following situations:
In the dark.
When the sun or the beam of headlights is shining
directly into the camera lens.
If ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water, and
wipe it with a soft cloth.
If the back of the vehicle is in an accident, the
position and mounting angle of the camera may
change or the camera may be affected. Be sure to
have the camera and its position and mounting angle
checked at your dealer.
Extreme high or low temperatures or extreme
temperature changes can affect the image displayed.
OnStar®System
OnStar uses several innovative technologies and live
advisors to provide you with a wide range of safety,
security, information, and convenience services. If your
airbags deploy, the system is designed to make an
automatic call to OnStar Emergency advisors who can
request emergency services be sent to your location.
If you lock your keys in the vehicle, call OnStar at
1-888-4-ONSTAR and they can send a signal to unlock
your doors. If you need roadside assistance, press
the OnStar button and they can contact Roadside
Service for you.
OnStar service is provided to you subject to the
OnStar Terms and Conditions. You may cancel your
OnStar service at any time by contacting OnStar.

How OnStar Service Works
Your vehicle’s OnStar system has the capability of
recording and transmitting vehicle information.
This information is automatically sent to an OnStar
Call Center at the time of an OnStar button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually includes
your GPS location and, in the event of a crash,
additional information regarding the accident that your
vehicle has been involved in (e.g. the direction from
which your vehicle was hit). When you use the Virtual
Advisor feature of OnStar Hands-Free Calling, your
vehicle also sends OnStar your GPS location so that we
can provide you with location-based services.
OnStar service cannot work unless your vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar
service also cannot work unless you are in a place
where the wireless service provider OnStar has hired for
that area has coverage, network capacity and reception
when the service is needed, and technology that is
compatible with the OnStar service. Not all services are
available everywhere, particularly in remote or
enclosed areas, or at all times.Location information about your vehicle is only available
if the GPS satellite signals are unobstructed and
available.
Your vehicle must have a working electrical system
(including adequate battery power) for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service to you at any particular time or place.
Some examples are damage to important parts of your
vehicle in an accident, hills, tall buildings, tunnels,
weather or wireless phone network congestion.
Your Responsibility
Increase the radio volume if you cannot hear the OnStar
advisor. If the light next to the OnStar buttons is red,
this means that your system is not functioning properly
and should be checked by your dealer/retailer. If the
light appears clear (no light is appearing), your OnStar
subscription has expired. You can always press the
OnStar button to conrm that your OnStar equipment
is active.
