Canada Standards RSS-210/220/310.
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, see
Fuses and
Circuit Breakers
on page 6‑101. If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your dealer who can service the PASS-Key
®III+ to
have a new key made. In an emergency, contact
Roadside Assistance. See Roadside Assistance
Program
on page 8‑6, 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 or a
locksmith who can service PASS-Key
®III+ to have keys
made and programmed to the system.
See your dealer 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.

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 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 five 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 lose or damage your PASS-Key
®III+ key, see
your dealer 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 first 500 miles (805 km). Do
not make full-throttle starts. Avoid
downshifting to brake or slow the vehicle.
.Avoid making hard stops for the first
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. See
Towing a Trailer (Automatic Transmission)
on page 5‑31or Towing a Trailer (Manual
Transmission)
on page 5‑37for the trailer
towing capabilities of your vehicle and more
information.
Following break‐in, engine speed and load can be
gradually increased.

Roof Rack System
The vehicle may have a roof rack system.
{WARNING:
If something is carried on top of the vehicle that is
longer or wider than the roof rack—like paneling,
plywood, or a mattress— the wind can catch it
while the vehicle is being driven. The item being
carried could be violently torn off, and this could
cause a collision, and damage the vehicle. Never
carry something longer or wider than the roof rack
on top of the vehicle unless using a GM Certified
accessory carrier.
For vehicles with a roof rack, the rack can be used to
load items. For roof racks that do not have crossrails
included, GM Certified crossrails can be purchased as
an accessory. See your dealer for additional
information.
Notice: Loading cargo on the roof rack that weighs
more than 75 kg (165 lbs) or hangs over the rear or
sides of the vehicle may damage the vehicle. Load
cargo so that it rests evenly between the crossrails,
making sure to fasten cargo 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.
To prevent damage or loss of cargo when driving, check
to make sure crossrails and cargo are securely
fastened. Loading cargo on the roof rack will make the
vehicle’s center of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may result in loss of control.
If driving for a long distance, on rough roads, or at high
speeds, occasionally stop the vehicle to make sure the
cargo remains in its place.
Do not exceed the maximum vehicle capacity when
loading the vehicle. For more information on vehicle
capacity and loading, see Loading the Vehicle
on
page 5‑22.

The 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 floor, to the rear liftgate or
liftgate glass. The net is not for larger, heavier loads.
