Passlock
R
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.
If the engine stalls and the SECURITY message flashes,
wait until the message 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 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” in the Index). See your dealer
for service.
In an emergency, call the GMC Roadside Assistance
Center. See “Roadside Assistance” in the Index.
New Vehicle “Break
-
In”
NOTICE:
Your vehicle doesn’t need an elaborate
“break
-
in.” But it will perform better in
the long run if you follow these guidelines:
D Keep your speed at 55 mph (88 km/h) or
less for the first 500 miles (805 km).
D Don’t drive at any one speed
--
fast or
slow
--
for the first 500 miles (805 km).
Don’t make full
-
throttle starts.
D Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren’t 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.
D Don’t tow a trailer during break
-
in.
See “Towing a Trailer” in the Index for
more information.
