Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the 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. SeeTowing
a Trailer on page 4-28for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
2-24

Ignition Positions
The ignition switch has four different positions:
In order to shift out of P (Park), ignition must be in the
ON/RUN or ACC/ACCESSORY and the brake pedal
must be applied.
Notice:Using a tool to force the key to turn in
the ignition could cause damage to the switch or
break the key. Use the correct key, make sure it is all
the way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer/retailer.A (LOCK/OFF):This is the only position in which the
ignition key can be inserted or removed. This position
locks the ignition and transmission and steering column.
The steering can bind with the wheels turned off
center. If this happens, move the steering wheel from
right 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
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN):This position is where the key returns to
after the vehicle is started. This position displays some
of the warning and indicator lights.
The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start the vehicle if the
battery is allowed to drain for an extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN
when the driver door is opened if the ignition is in
LOCK/OFF, ACC/ACCESSORY and the key is in the
ignition. SeeDIC Warnings and Messages on page 3-73
for more information.

Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 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 minutes
or until the driver’s door is opened. For an additional
10 minutes of power, close all the doors and turn the key
to ON/RUN and then back to LOCK/OFF.
Starting the Engine
Move the shift lever to P (Park) or N (Neutral).
The engine will not start in any other position.
To restart the engine when the vehicle is already
moving, use N (Neutral) only.
Notice:Do not try to shift to P (Park) if the vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the vehicle
is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition to START. When the engine starts, let go of
the key. The idle speed will slow down as the engine
warms. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently to allow the oil to warm up and lubricate all
moving parts.
2-26

The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects components. If the ignition
key is turned to the START position, and then
released when the engine begins cranking, the
engine will continue cranking for a few seconds or
until the vehicle starts. If the engine does not
start and the key is held in START, cranking will be
stopped after 15 seconds to prevent cranking
motor damage. To prevent gear damage, this
system also prevents cranking if the engine
is already running. Engine cranking can be
stopped by turning the ignition switch to the
ACC/ACCESSORY or LOCK/OFF position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. 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 ooded with too much gasoline.
Try pushing the accelerator pedal all the way to
the oor and holding it there as you hold the
key in START for up to a maximum of 15 seconds.
Wait at least 15 seconds between each try, to
allow the cranking motor to cool down. When the
engine starts, let go of the key and accelerator.
If the vehicle starts briey but then stops again,
repeat these steps. This clears the extra gasoline
from the engine. Do not race the engine
immediately after starting it. Operate the engine
and transmission gently until the oil warms up and
lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.
2-27

Automatic Transmission Operation
The automatic transmission may have a shift lever
located either on the steering column or on the console
between the seats.
There are several different positions for the shift lever.
P (Park):This position locks the front wheels. It is
the best position to use when you start the engine
because the vehicle cannot move easily.{CAUTION:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
rmly 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 2-33. If you are pulling a trailer,
seeTowing a Trailer on page 4-28.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes before you can shift from
P (Park) while the ignition key is in ON/RUN. If you
cannot shift out of P (Park), ease pressure on the shift
lever. Push the shift lever all the way into P (Park)
as you maintain brake application. Then move the shift
lever into another gear. SeeShifting Out of Park on
page 2-34.

Shifting Into Park
{CAUTION:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake rmly set. The vehicle can roll. 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, use the steps that follow.

Leaving the Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake rmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch re. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you have to leave the vehicle with the engine running,
be sure your vehicle is in P (Park) and the parking
brake is rmly set before you leave it. SeeParking Brake
on page 2-32for more information.
Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting
the transmission into P (Park) is not done properly and
then it is difficult to shift out of P (Park). To prevent
torque lock, set the parking brake and then shift into
P (Park). To nd out how, see “Shifting Into Park” in this
section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
Shifting Out of Park
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal unless the shift lever
is in P (Park)
Prevent movement of the shift lever out of
P (Park), unless the ignition is in ON/RUN or
ACC/ACCESSORY and the regular brake pedal
is applied.
2-34

The shift lock is always functional except in the case
of a an uncharged or low voltage (less than 9 volt)
battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 5-38.
Console Shift

2-35

Engine Exhaust
{CAUTION:
Engine exhaust contains Carbon Monoxide (CO)
which cannot be seen or smelled. Exposure to
CO can cause unconsciousness and even death.
Exhaust may enter the vehicle if:
The vehicle idles in areas with poor ventilation
(parking garages, tunnels, deep snow that
may block underbody airow or tail pipes).

Park Tilt Mirrors
If your vehicle is equipped with memory mirrors,
it is capable of performing the park tilt mirror feature.
This feature allows the driver and passenger side
mirror to tilt to a factory programmed position when
the vehicle is in R (Reverse). This feature may be
useful in allowing you to view the curb when you are
parallel parking.
When the vehicle is shifted out of R (Reverse) and
either a ve-second delay has occurred, or the
ignition is turned to LOCK/OFF, the driver and
passenger side mirror will return to its original
position.
This feature can be enabled/disabled through
the Driver Information Center (DIC). SeeDIC
Vehicle Customization on page 3-86for more
information.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you could
hit a vehicle on the right. Check the inside mirror or
glance over your shoulder before changing lanes.
The passenger side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver seat.
