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. See
Fuses and Circuit Breakers on page 356.Ifthe
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 408.

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 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
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.
Following break-in, engine speed and load can
be gradually increased.
