Starting And Operating Your Vehicle; New Vehicle Break-In - GMC 2005 Envoy Owner's Manual

During normal operation, the security light will turn 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 light comes
on, you will be able to restart the engine if you turn the
engine off. However, your Passlock
working properly and must be serviced by your dealer.
Your vehicle is not protected by Passlock
time. You may also want to check the fuse. See Fuses
and Circuit Breakers on page 5-91. See your dealer
for service.
In an emergency, call the GM Roadside Assistance
Center. See Roadside Assistance Program on page 7-5.

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.
