Immobilizer Operation
(Canada Only)
This vehicle has a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from
the ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN.
You do not have to manually arm or
disarm the system.
The security light comes on if there
is a problem with arming or
disarming the theft-deterrent system.
The key uses a transponder that
matches an immobilizer control unit
in the vehicle. Only the correct
key starts the vehicle. If the key is
ever damaged, the vehicle may
not start.When trying to start the vehicle,
if the engine does not start and
the security light comes on,
there may be a problem with the
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. Check
the fuse. SeeFuses and Circuit
Breakers on page 5-91. If the engine
still does not start with the other
key, the vehicle needs service.
If the vehicle does start, the rst
key may be faulty. See your
dealer/retailer who can service the
theft-deterrent system and have
a new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys can
be programmed for the vehicle.
The following procedure is for
programming additional keys only.Canadian Owners:If the keys
are lost or damaged, only a
dealer/retailer can service the
theft-deterrent system to have new
ones made. Two current driver’s
keys are required to program
additional keys.
To program a new key:
1. Verify that the new key has
PK3+ stamped on it.
2. Insert the current driver’s key in
the ignition and start the engine.
If the engine does not start see
your dealer/retailer for service.
3. After the engine has started,
turn the key to LOCK/OFF,
and remove the key.

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:
Keep your speed at 55 mph
(88 km/h) or less for the
rst 500 miles (805 km).
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 on page 4-42for the
trailer towing capabilities of the
vehicle and more information.
Following break-in, engine
speed and load can be gradually
increased.

OnStar service cannot work unless
the 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 the vehicle is 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 the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.
The vehicle must have a working
electrical system, including adequate
battery power, for the OnStar
equipment to operate. There are
other problems OnStar cannotcontrol that may prevent OnStar
from providing OnStar service at
any particular time or place.
Some examples are damage to
important parts of the vehicle in a
crash, hills, tall buildings, tunnels,
weather or wireless phone network
congestion.
Your Responsibility
Increase the volume of the radio
if the OnStar advisor cannot
be heard. If the light next to the
OnStar buttons is red, the system
may not be functioning properly.
Press the OnStar button and request
a vehicle diagnostic. If the light
appears clear (no light is appearing),

siderails and can be moved back
and forth to accommodate various
cargo sizes.
Notice:Loading cargo on the
luggage carrier that weighs more
than 250 lbs. (113 kg) or hangs
over the rear or sides of the
vehicle may damage the vehicle.
Load cargo only on top of the
crossrails and tie the cargo down
to the crossrail support cargo
tie-down loops, making sure
to fasten it securely
Do not exceed the maximum vehicle
capacity when loading your vehicle.
For more information on vehicle
capacity and loading, seeLoading

crossrail stop tab in the siderail.
This tab prevents the crossrail from
being moved past the opening of
the sunroof and cargo from
being loaded too far forward.
The vehicle may have cargo tie
downs. Once the cargo is loaded
onto the crossrails, use the cargo tie
downs to secure it. Do not load
cargo directly on the roof of the
vehicle. SeeCargo Tie Downs on
page 2-49for more information.
