When trying to start the vehicle, if the engine does not
start and the security light continues flashing, the key
may have a damaged transponder. Turn the ignition off
and try again.
If the engine still does not start, and the key appears to be
undamaged, try another key. At this time, you may also
want to check the fuse. SeeFuses and Circuit Breakers
on page 5-75. 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 have a new key made.
Up to five keys may be programmed for the vehicle.
If you lose or damage your keys, only a GM dealer can
have new keys made.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however,
is not working properly and must be serviced by
your dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside Assistance. See
Roadside Assistance Program on page 7-6.Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your 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 your 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 4-35for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
