GMC 2004 Savana - Manual (Page 106)

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 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 is running and the SECURITY light 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 5-91. See your
dealer for service.
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 4-37 for more information.
