{WARNING:
A crash severe enough to inflate the airbags may
have also damaged important functions in the
vehicle, such as the fuel system, brake and
steering systems, etc. Even if the vehicle appears
to be drivable after a moderate crash, there may
be concealed damage that could make it difficult
to safely operate the vehicle.
Use caution if you should attempt to restart the
engine after a crash has occurred.
In many crashes severe enough to inflate the airbag,windshields are broken by vehicle deformation.Additional windshield breakage may also occur from theright front passenger airbag.
•Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts forthe airbag system. If you do not get them, the airbagsystem will not be there to help protect you inanother crash. A new system will include airbagmodules and possibly other parts. The servicemanual for your vehicle covers the need to replaceother parts.
•The vehicle has a crash sensing and diagnostic
module which records information after a crash.SeeVehicle Data Recording and Privacy onpage 8-18andEvent Data Recorders on page 8-19.
•Let only qualified technicians work on the airbag
systems. Improper service can mean that anairbag system will not work properly. See yourdealer/retailer for service.
Passenger Sensing System
The vehicle has a passenger sensing system for theright front passenger position. The passenger airbagstatus indicator will be visible on the overhead consolewhen the vehicle is started.
The words ON and OFF, or the symbol for on and off,are visible during the system check. If you are usingremote start, if equipped, to start the vehicle froma distance, you may not see the system check.

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.

Automatic Transmission Operation
The automatic transmission may have a shift leverlocated either on the steering column or on the consolebetween the seats.
There are several different positions for the shift lever.
P (Park):This position locks the front wheels. It isthe best position to use when you start the enginebecause the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park on page 3-31. If you are pulling a trailer, see
Towing a Trailer on page 5-26.
Make sure the shift lever is fully in P (Park) beforestarting the engine. The vehicle has an automatictransmission shift lock control system. You have to fullyapply the regular brakes before you can shift fromP (Park) while the ignition key is in ON/RUN. Ifyou cannot shift out of P (Park), ease pressure on theshift lever. Push the shift lever all the way into P (Park)as you maintain brake application. Then move theshift lever into another gear. SeeShifting Out of Park onpage 3-32.
