Hummer 2006 H3 - Manual (Page 90)

Passlock ®
Your vehicle has 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 an incorrect key is used or the
ignition lock cylinder is tampered with, the fuel system
is disabled and the vehicle will not start.
During normal operation, the security light will turn off
approximately five seconds after the engine is started.
See Security Light on page 3-39.
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
® system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
® at
this time. See your dealer for service.
In an emergency, call the 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 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.
• Do not tow a trailer during break-in. See Towing
a Trailer on page 4-58 for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
