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:
•
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 327 for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.

Ignition Positions

With the ignition key in the ignition, the key can be
turned to four different positions:
Notice: Using a tool to force the key from the
ignition switch could cause damage or
break the key. Use the correct key and turn the
key only with your hand. Make sure the key
is in all the way. If none of this works,
then your vehicle needs service.
A (OFF): This is the only position in which the
ignition key can be inserted or removed. This
position locks the ignition and transaxle. It is a
theft-deterrent feature.
