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.

Ignition Positions
The ignition switch has four different positions:
In order to shift out of P (Park), ignition must be in theON/RUN or ACC/ACCESSORY and the brake pedalmust be applied.
Notice:Using a tool to force the key to turn in theignition could cause damage to the switch orbreak the key. Use the correct key, make sure it isall the way in, and turn it only with your hand. If thekey cannot be turned by hand, see yourdealer/retailer.
A (LOCK/OFF):This is the only position in which theignition key can be inserted or removed. This positionlocks the ignition and transmission and steering column.
The steering can bind with the wheels turned offcenter. If this happens, move the steering wheel fromright to left while turning the key to ACC/ACCESSORY.If this doesn’t work, the vehicle needs service.
B (ACC/ACCESSORY):This position lets the radio andwindshield wipers operate while the engine is off. Touse ACC/ACCESSORY, turn the key clockwise.
3-23

C (ON/RUN):This position is where the key returns toafter the vehicle is started. This position displayssome of the warning and indicator lights.
The battery could be drained if you leave the key in theACC/ACCESSORY or ON/RUN position with the engineoff. You may not be able to start the vehicle if the batteryis allowed to drain for an extended period of time.
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.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to10 minutes after the ignition key is turned off:
•Audio System
•Audio Steering Wheel Controls
•Power Windows
•Sunroof (if equipped)
Power to these accessories will work up to 10 minutesor until the driver’s door is opened. For an additional10 minutes of power, close all the doors and turn the keyto ON/RUN and then back to LOCK/OFF.
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.
3-24

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. Before adding electrical equipment, checkwith your dealer/retailer. If you do not, the enginemight not perform properly. Any resulting damagewould not be covered by the vehicle warranty.

Engine Coolant Heater
The engine coolant heater can provide easier startingand better fuel economy during engine warm-up in coldweather conditions at or below 0°F (!18°C). Vehicleswith an engine coolant heater should be pluggedin at least four hours before starting.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver sideof the engine, behind the transmission dipstick/fluidfill location and next to the engine.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug andstore the cord as it was before to keep it awayfrom moving engine parts and prevent damage.
The length of time the heater should remain plugged independs on several factors. Ask a dealer/retailer inthe area where you will be parking the vehicle for thebest advice on this.
