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.

D (START):This position starts the engine.
A warning chime will sound and the Driver InformationCenter (DIC) will display DRIVER DOOR OPENwhen the driver door is opened if the ignition is inLOCK/OFF, ACC/ACCESSORY and the key is in theignition. SeeDIC Warnings and Messages on page 4-67for more information.

Starting the Engine
Move the shift lever to P (Park) or N (Neutral). Theengine will not start in any other position. To restart theengine when the vehicle is already moving, useN (Neutral) only.
Notice:Do not try to shift to P (Park) if the vehicleis moving. If you do, you could damage thetransmission. Shift to P (Park) only when the vehicleis stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn theignition to START. When the engine starts, let goof the key. The idle speed will slow down asthe engine warms. Do not race the engineimmediately after starting it. Operate the engine andtransmission gently to allow the oil to warm upand lubricate all moving parts.

The vehicle has a Computer-Controlled CrankingSystem. This feature assists in starting theengine and protects components. If the ignition keyis turned to the START position, and thenreleased when the engine begins cranking, theengine will continue cranking for a few seconds oruntil the vehicle starts. If the engine does notstart and the key is held in START, cranking will bestopped after 15 seconds to prevent crankingmotor damage. To prevent gear damage, thissystem also prevents cranking if the engineis already running. Engine cranking can be stoppedby turning the ignition switch to theACC/ACCESSORY or LOCK/OFF position.
Notice:Cranking the engine for long periods oftime, by returning the key to the START positionimmediately after cranking has ended, can overheatand damage the cranking motor, and drain thebattery. Wait at least 15 seconds between each try,to let the cranking motor cool down.
2. If the engine does not start after 5-10 seconds,especially in very cold weather (below 0°F or!18°C), it could be flooded with too much gasoline.Try pushing the accelerator pedal all the way tothe floor and holding it there as you hold the key inSTART for up to a maximum of 15 seconds.Wait at least 15 seconds between each try, to allowthe cranking motor to cool down. When theengine starts, let go of the key and accelerator. Ifthe vehicle starts briefly but then stops again, repeatthese steps. This clears the extra gasoline fromthe engine. Do not race the engine immediatelyafter starting it. Operate the engine andtransmission gently until the oil warms up andlubricates all moving parts.
Notice:The engine is designed to work with theelectronics in the vehicle. If you add electrical partsor accessories, you could change the way the engineoperates.
