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 4-71 for more information.

Ignition Positions

With the key in the ignition switch, you can turn it to four
different positions.
A (LOCK): This position locks your ignition when the
key is removed. The steering locks when equipped with
a manual transmission. It is a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK
B (ACCESSORY): This position allows you to use
things like the radio, power windows and the windshield
wipers when the engine is off.
