5. After the engine has started, turn
the key to LOCK/OFF, and
remove the key. Insert the key to
be programmed and turn it to
ON/RUN within ten seconds of
removing the previous key.
The security light turns off once
the key has been programmed.

if additional keys are to be
programmed.
If the security light comes on and
stays on while driving, the engine
will restart if you turn it off. However,
the theft-deterrent system is not
working properly and must be
serviced by your dealer/retailer.
The vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside
Assistance. SeeRoadside Service
on page 7-6.

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:
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.

Many insurance policies provide
reduced protection to your GM
vehicle by limiting compensation for
damage repairs by using aftermarket
collision parts. Some insurance
companies will not specify
aftermarket collision parts. When
purchasing insurance, we
recommend that you assure your
vehicle will be repaired with GM
original equipment collision parts. If
such insurance coverage is not
available from your current insurance
carrier, consider switching to another
insurance carrier.
If your vehicle is leased, the leasing
company may require you to
have insurance that assures repairs
with Genuine GM Original
Equipment Manufacturer (OEM)
parts or Genuine Manufacturer
replacement parts. Read your lease
carefully, as you may be charged
at the end of your lease for
poor quality repairs.If a Crash Occurs
Here is what to do if you are
involved in a crash.
Try to relax and then check to
make sure you are all right. If
you are uninjured, make sure that
no one else in your vehicle, or
the other vehicle, is injured.
If there has been an injury, call
emergency services for help.
Do not leave the scene of a crash
until all matters have been
taken care of. Move your vehicle
only if its position puts you in
danger or you are instructed to
move it by a police officer.
Give only the necessary and
requested information to
police and other parties involved
in the crash. Do not discuss
your personal condition, mental
frame of mind, or anything
unrelated to the crash. This will
help guard against post-crash
legal action.
If you need roadside assistance,
call GM Roadside Assistance.
SeeRoadside Service on
page 7-6for more information.
If your vehicle cannot be driven,
know where the towing service
will be taking it. Get a card from
the tow truck operator or write
down the driver’s name, the
service’s name, and the phone
number.
Remove any valuables from your
vehicle before it is towed away.
Make sure this includes your
insurance information and
registration if you keep these
items in your vehicle.
