Starting And Operating Your Vehicle - GMC 2004 Sonoma Owner's Manual

®
Passlock
Your vehicle is equipped with the
®
Passlock theft-deterrent system.
®
Passlock is a passive theft-deterrent system.
®
Passlock enables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used or the
ignition lock cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will
go off approximately five seconds after the key is turned
to RUN.
If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing before
trying to restart the engine. Remember to release the
key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the SECURITY message
comes on, you will be able to restart the engine if
you turn the engine off. However, your
®
Passlock system is not working properly and must be
serviced by your dealer. Your vehicle is not protected
®
by Passlock at this time. You may also want to check
the fuse. See Fuses and Circuit Breakers on page 5-95.
See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. 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:
•
Keep your speed at 55 mph (88 km/h) or less for
the first 500 miles (805 km).
•
Do not drive at any one speed — fast or
slow — for the first 500 miles (805 km). Do not
make full-throttle starts.
•
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.
•
Do not tow a trailer during break-in. See Towing
a Trailer on page 4-55 for more information.
