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 4-62 for more information.
Ignition Positions
Use the key to turn the ignition switch to four different
positions.
A (Lock): This position locks the ignition and
transmission. It is a theft-deterrent feature. You will only
be able to remove the key when the ignition is turned
to LOCK.
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.
