A (LOCK/OFF):This is the only
position from which you can remove
the key. This locks the steering
wheel, ignition and automatic
transmission.
On vehicles with an automatic
transmission, the shift lever must
be in P (Park) to turn the ignition
switch to the LOCK/OFF position.
The ignition switch can bind in
the LOCK/OFF position 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
position provides power to some
of the electrical accessories.
It unlocks the steering wheel and
ignition. The transmission is
also unlocked in this position
on automatic transmission
vehicles. To move the key from
ACC/ACCESSORY to LOCK/OFF,
push in the key and then turn it
to LOCK/OFF.C (ON/RUN):The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, including the ventilation
fan and 12 volt power outlet, as
well as to display some 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. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
A warning tone will sound when the
driver door is opened when the
ignition is still in ACC/ACCESSORY
and the key is in the ignition.Retained Accessory

the driver door is opened.
Driving and Operating 8-3

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 Neutral
and the parking brake engaged.
Hold the clutch pedal down to
the oor and start the engine. The
vehicle will not start if the clutch
pedal is not all the way down.Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition key to
START. When the engine starts,
let go of the key. The idle speed
will go 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 for
many seconds, cranking will be
stopped after 15 secondsto 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 ACC/
ACCESSORY or LOCK/OFF.
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. Push the
accelerator pedal all the way to
the oor and holding it there as
you hold the key in START for
a maximum of 15 seconds.
8-4 Driving and Operating

Wait at least 15 seconds between
each try, to allow the cranking
motor to cool. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briey but then stops again,
repeat the procedure. 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, if
available, can help in cold weather
conditions at or below 0°F (−18°C)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting your
vehicle. An internal thermostat in the
plug-end of the cord 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 electrical cord is located on
the driver side of the engine
compartment, behind the
air cleaner for V8 models.
The electrical cord is located
on the passenger side of
the engine compartment, behind
the engine compartment fuse
block for V6 models.3. Plug it into a normal, grounded
110-volt AC outlet.
{CAUTION
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a re. 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 as it was before to keep
it away from moving engine
parts. If you do not it could be
damaged.

Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that lets you know when to change
the engine oil and lter. This is
based on engine revolutions and
engine temperature, and not
on mileage. Based on driving
conditions, the mileage at which an
oil change will be indicated can
vary considerably. For the oil
life system to work properly, you
must reset the system every
time the oil is changed.
When the system has calculated
that oil life has been diminished,
it will indicate that an oil change is
necessary. The Service Engine
Oil message will be displayed.Change the oil as soon as possible
within the next 600 miles (1 000 km).
It is possible that, if you are driving
under the best conditions, the oil life
system might not indicate that an oil
change is necessary for over a year.
However, the engine oil and lter
must be changed at least once a
year and at this time the system must
be reset. Your dealer/retailer has
trained service people who will
perform this work using genuine
parts and reset the system. It is also
important to check the oil regularly
and keep it at the proper level.
If the system is ever reset
accidentally, you must change
the oil at 3,000 miles (5 000 km)
since the last oil change. Remember
to reset the oil life system whenever
the oil is changed.
How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where you
change the oil prior to the Service
Engine Oil message being displayed,
reset the system.
After changing the engine oil, reset
the system:
1. Turn the ignition key to ON/RUN
with the engine off.
2. Fully press and release the
accelerator pedal three times
within ve seconds.
If the Service Engine Oil
message does not appear,
the system is reset.
If the Service Engine Oil message
displays, reset the system again.
