Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
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 a correct key is not used or the
ignition lock cylinder is tampered with, the fuel system
is disabled and the vehicle will not start.
During normal operation, the THEFT SYSTEM light will
turn off approximately five seconds after the ignition
key is turned to ON and the engine is started.
After attempting to start the engine, if the THEFT
SYSTEM light flashes or stays on, wait ten minutes with
the key in ON until the light goes off. Then turn the
ignition to OFF before attempting to start the engine
again.
Starting and Operating Your

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:
•
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 4-38 for more information.
