60 seconds with any door open.Press the lock button on the RKE transmitter a second
time, while all the doors are closed, to immediately arm
the system. The system still arms in 60 seconds if a door
is open. When the open door is closed, it also arms.
The security light turns on to indicate that arming has
been initiated. Once the system is armed, the security
light ashes once every three seconds.
If the security light ashes twice per second, a door
is open.
Locking the vehicle with the manual lock knobs on the
doors will not arm the system.
Disarming the System
Disarm the system by doing any one of the following:
Press the RKE transmitter unlock button.
Turn the ignition on.
Once the system is disarmed, the security light stops
ashing.

How the System Alarm is Activated
If the system is armed, it can be activated by either:
Opening the driver’s door or tailgate. This causes a
10 second pre-alarm chirp followed by a 30 second
full alarm of horn and lights.
Opening any other door. This immediately causes a
full alarm of horn and lights for 30 seconds.
When an alarm event has nished, the system re-arms
itself automatically.
How to Turn Off the System Alarm
To turn off the system alarm, do one of the following:
Press the lock button on the RKE transmitter.
The system will then re-arm itself.
Press the unlock button on the RKE transmitter.
This will also disarm the system.
Insert the key in the ignition and turn it on. This will
also disarm the system.
How to Detect a Tamper Condition
The content theft security system alarm was previously
activated if three chirps sound when you press the
lock or unlock buttons on the RKE transmitter.

PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®III+ is a passive theft-deterrent system.
The system is automatically armed when the key is
removed from the ignition.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
When trying to start the vehicle if the engine does not
start and the security light comes on, there may be a
problem with your theft-deterrent system. Turn the
ignition off and try again.If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time, you
may also want to check the fuse, seeFuses and Circuit
Breakers on page 5-109. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See your
dealer/retailer who can service the PASS-Key
®III+ to
have a new key made. In an emergency, contact
Roadside Assistance. SeeRoadside Assistance Program
on page 7-7, for more information.
It may be possible for the PASS-Key
®III+ decoder to
“learn” the transponder value of a new or replacement
key. Up to 10 keys may be programmed for the vehicle.
The following procedure is for programming additional
keys only. If all the currently programmed keys are
lost or do not operate, you must see your dealer/retailer
or a locksmith who can service PASS-Key
®III+ to
have keys made and programmed to the system.
See your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.
2-21

To program the new key:
1. Verify that the new key has a
1stamped on it.
2. Insert the already programmed key in the ignition
and start the engine. If the engine will not start,
see your dealer/retailer for service.
3. After the engine has started, turn the key to
LOCK/OFF, and remove the key.
4. Insert the key to be programmed and turn it to the
ON/RUN position within ve seconds of the original
key being turned to the LOCK/OFF position.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security light comes on
and stays on, you may be able to restart your engine if
you turn it off. Your PASS-Key
®III+ system, however,
is not working properly and must be serviced by your
dealer/retailer. Your vehicle is not protected by the
PASS-Key
®III+ system at this time.
If you lose or damage your PASS-Key
®III+ key,
see your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer (Automatic Transmission) on page 4-34
orTowing a Trailer (Manual Transmission) on
page 4-41for the trailer towing capabilities of
your vehicle and more information.
Following break-in, engine speed and load can be
gradually increased.
2-22

The rear vision camera system display in the rearview
mirror may turn off or not appear as expected due to one
of the following conditions. If this occurs the left indicator
light on the mirror will ash.
A slow ash may indicate a loss of video signal, or no
video signal present during the reverse cycle.
A fast ash may indicate that the display has been on
for the maximum allowable time during a reverse
cycle, or the display has reached an Over
Temperature limit.
The fast ash conditions are used to protect the video
device from high temperature conditions. Once
conditions return to normal the device will reset and
the green indicator will stop ashing.
During any of these fault conditions, the display will be
blank and the indicator will continue to ash as long
as the vehicle is in R (Reverse) or until the conditions
return to normal.
Pressing and holding
zwhen the left indicator light is
ashing will turn off the video display along with the
left indicator light.

{CAUTION:
If something is carried on top of the vehicle that is
longer or wider than the luggage carrier — like

cause a driver to lose control. The item being
carried could be violently torn off, and this could
cause a collision, and damage the vehicle. Items
may be carried inside. Never carry something
longer or wider than the luggage carrier on top of
the vehicle.
Notice:Loading cargo on the luggage carrier that
weighs more than 150 lbs (68 kg) or hangs over
the rear sides of the vehicle may damage your
vehicle. Load cargo so that it rests on the slats
as far forward as possible and against the side
rails making sure to fasten it securely.Notice:Loading cargo directly on the roof of the
vehicle may cause damage to the vehicle and would
not be covered under warranty. Do not place
cargo on the roof the vehicle.
Do not exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, seeLoading the Vehicle on
page 4-25.
To prevent damage or loss of cargo as you are driving,
check frequently to ensure your cargo is securely
fastened.
The roof rack system has siderails that are attached to
the roof. All cargo must be loaded on the luggage
carrier crossrails only.
Use GM accessory racks that are compatible with your
roof rack system, these are available at your GM dealer.
Convenience Net
Your vehicle may have a convenience net. The metal
rings in the cargo area can be used to attach the
convenience net for several uses. The net can be used
to attach items secured to the oor, to the rear liftgate
or liftgate glass. The net is not for larger, heavier loads.
