The theft-deterrent system will not arm if you lock thedoors with a key or use the manual door lock. Itarms only if you use a power door lock with the dooropen or the RKE transmitter.

door lock.
•Always unlock a door with a key or use the
RKE transmitter system. Pressing the unlock buttonon the RKE transmitter, or unlocking a door withthe key disarms the content theft-deterrent system.Unlocking a door any other way will activate thealarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the driver’sdoor with your key. You can also turn off the alarmby using the unlock button on the RKE transmittersystem, or by starting the car with a valid key.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaboratebreak-in. But it will perform better in the long run ifyou follow these guidelines:
•Do not drive at any one constant speed, fast or
slow, for the first 500 miles (805 km). Do notmake full-throttle starts. Avoid downshifting tobrake or slow the vehicle.
•Avoid making hard stops for the first 200 miles
(322 km) or so. During this time the new brakelinings are not yet broken in. Hard stopswith new linings can mean premature wear andearlier replacement. Follow this breaking-inguideline every time you get new brake linings.
•Do not tow a trailer during break-in. SeeTowing
a Trailer on page 5-26for the trailer towingcapabilities of your vehicle and moreinformation.
Following break-in, engine speed and load can begradually increased.
