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 4-63 for more information.
Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions.
A (LOCK): This position locks your ignition and
transmission. It’s a theft-deterrent feature. You will
only be able to remove your key when the ignition is
turned to LOCK.
