Replacing Restraint System Parts
After a Crash
{WARNING:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.
If the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.
But the safety belt assemblies that were used during any
crash may have been stressed or damaged. See your
dealer/retailer to have the safety belt assemblies
inspected or replaced.If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH system
parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was
not being used at the time of the crash.
If an airbag inflates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the
vehicle has been in a crash, if the airbag readiness light
stays on after the vehicle is started, or while you are
driving. SeeAirbag Readiness Light on page 4-22.

Keys
{WARNING:
Leaving children in a vehicle with the ignition key
is dangerous for many reasons, children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function with the keys in the ignition and children
could be seriously injured or killed if caught in the
path of a closing window. Do not leave the keys in
a vehicle with children.
The key can be used for the ignition, all door locks, and
the tailgate.
The key has a bar-coded key tag that the dealer/retailer
or qualified locksmith can use to make new keys.
Store this information in a safe place, not in your vehicle.
Notice:If you ever lock your keys in the vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you are locked out of your vehicle, call the Roadside
Assistance Center. SeeRoadside Assistance Program
on page 8-7.

Doors and Locks
Door Locks
{WARNING:
Unlocked doors can be dangerous.
•Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
will not open it. The chance of being thrown
out of the vehicle in a crash is increased if the
doors are not locked. So, all passengers
should wear safety belts properly and the
doors should be locked whenever the vehicle
is driven.
WARNING: (Continued)

Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), turn the ignition to ON/RUN and
apply the regular brake pedal.
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 on automatic transmission
vehicles. It locks the steering wheel on manual
transmission vehicles. The key can on be removed
in LOCK/OFF.On vehicles with an automatic transmission, the shift
lever must be in P (Park) to turn the ignition switch
to LOCK/OFF.
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, then the vehicle needs service.
(B) ACC/ACCESSORY:This is the position in which
you can operate the electrical accessories or items
plugged into the accessory power outlets. On automatic
transmission vehicles, this position unlocks the
ignition. On manual transmission vehicles, it unlocks the
ignition and steering wheel. Use this position if the
vehicle must be pushed or towed.
(C) ON/RUN:This position can be used to operate
the electrical accessories and to display some
instrument panel cluster warning and indicator lights.
The switch stays in this position when the engine
is running. The transmission is also unlocked in this
position on automatic transmission vehicles.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start your vehicle
if the battery is allowed to drain for an extended period
of time.
3-17

START (D):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
20 minutes after the engine is turned off:
•Audio System
•Wipers
•Power Windows
These features work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF, power to these features
continue to work for up to 20 minutes or until a door
is opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral).
The engine will not start in any other position.
To restart the vehicle when it 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.
Manual Transmission
The shift lever should be in N (Neutral) and the parking
brake engaged. Hold the clutch pedal down to the
floor and start the engine. The vehicle will not start if the
clutch pedal is not all the way down.

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. An internal
thermostat in the plug-end of the cord may exist
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 located in the engine compartment
behind the underhood fuse block on the driver side
of the vehicle.
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 and
store the cord to prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.
3-20

Automatic Transmission Operation
The vehicle has a shift lever on the steering column.
It features an electronic shift position indicator within the
instrument cluster. This display is powered anytime
the shift lever is capable of being moved out of P (Park).
This means that if the ignition is turned off, but not in
LOCK/OFF, there will be a small current drain on
the battery which could discharge the battery over a
period of time. If you need to leave the key in the ignition
but not in LOCK/OFF for an extended period, it is
recommended that you disconnect the battery cable
from the battery to prevent discharging the battery.
There are several different positions for the shift lever.
P (Park):This position locks the rear wheels. It is
the best position to use when you start the engine
because 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 (Automatic Transmission) on page 3-31.
If you are pulling a trailer, seeTowing a Trailer on
page 5-48.
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 must fully
apply the brake pedal before you can shift from P (Park)
when the ignition key is in ON/RUN. If you cannot
shift out of P (Park), ease pressure on the shift lever by
pushing 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
(Automatic Transmission) on page 3-32.
