Trunk
{CAUTION:
Exhaust gases may enter the vehicle if it is driven
with the liftgate, trunk/hatch open, or with any
objects that pass through the seal between the
body and the trunk/hatch or liftgate. Engine
exhaust contains Carbon Monoxide (CO) which
cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle must be driven with the liftgate, or
trunk/hatch open:
Close all of the windows
Fully open the air outlets on or under the
instrument panel
Adjust the Climate Control system to a setting
that brings in only outside air and set the fan
speed to the highest setting. See Climate
Control System in the Index.
If the vehicle is equipped with a power liftgate,
disable the power liftgate function.
For more information about carbon monoxide, see
Engine Exhaust on page 2-33.
Opening the Trunk
To open the trunk from the outside, use the Remote
Keyless Entry (RKE) transmitter. SeeRemote Keyless
Entry (RKE) System Operation on page 2-4for more
information.
The ignition must be off, or the transmission must be in
(P) Park to open the trunk.
Remote Trunk Release
This feature is used to unlock the trunk from inside the
vehicle using the power door lock switch.
Press and hold the top of
the driver’s or front
passenger’s power door
lock switch to unlock
the trunk.
The vehicle must be in (P) Park to unlock the trunk.

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.
Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
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 position locks the ignition. It also
locks the transmission. This is the only position in
which the ignition key can be inserted or removed.
2-21

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.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.
2-23

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.Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting. Some models have
an internal thermostat in the cord which will prevent
engine coolant heater operation at temperatures above
0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is attached to the underside of the diagonal
brace, which is located above the engine air
cleaner/lter assembly.
3. Plug it into a normal, grounded 110-volt AC outlet.
2-24

Automatic Transmission Operation
The vehicle’s automatic
transmission may have a
shift lever on the steering
column or on the console
between the seats.
There is also a display
located on the instrument
panel cluster that
indicates the vehicle’s
gear position.{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 2-29. If you are pulling a trailer, see
Towing a Trailer on page 4-28. Console Shift Lever
2-26

The positions for the shift lever are:
P (Park):This position locks the vehicle’s front wheels.
It is the best position to use when the engine is
started because the vehicle cannot move easily.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an electronic shift
lock release system. You must fully apply the brakes
before shifting from P (Park) when the ignition is
in ON/RUN. If you cannot shift out of P (Park), ease
pressure on the shift lever by pushing it 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 2-32.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
R (Reverse):Use this gear to back up.
To rock the vehicle back and forth in order to get it out
of snow, ice, or sand without damaging the transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 4-19.N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is moving, use N (Neutral) only. Also, use
N (Neutral) when the vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is rmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
