Engine Coolant Heater
If your vehicle has this feature, in very cold weather
0°F (−18°C) or colder, the engine coolant heater can
help. You will get easier starting and better fuel economy
during engine warm-up. Usually, the coolant heater
should be plugged in a minimum of four hours prior to
starting your vehicle. At temperatures above 32°F (0°C),
use of the coolant heater is not required. Your vehicle
may also have an internal thermostat in the plug end of
the cord. This will prevent operation of the engine coolant
heater when the temperature is at or above 0°F (−18°C)
as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located on the passenger’s side of
the engine compartment, near the radiator.
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.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

LOW TWO (L2):This position gives you more
power but lower fuel economy than AUTOMATIC
OVERDRIVE (D). You can use LOW TWO (L2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to
use your brakes off and on.
Notice:Do not drive in LOW TWO (L2) for more
than 25 miles (40 km), or at speeds over 55 mph
(90 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE (D) or LOW
FOUR (L4) as much as possible. Do not shift into
LOW TWO (L2) unless you are going slower
than 65 mph (105 km/h) or you can damage
your engine.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transaxle. If you are stuck, do not
spin the tires. When stopping on a hill, use the brakes
to hold the vehicle in place.Transaxle Overheating
If the transaxle uid temperature rises above
284°F (140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-30for
more information. When the transaxle overheats it
will go into a protection mode and will default shift into
fth gear if in the AUTOMATIC OVERDRIVE (D)
position, or second gear if in the LOW TWO (L2)
position. Continue driving the vehicle in either position
depending on the required vehicle speed and load.
Once the uid temperature lowers to the normal
temperature range, the transaxle will return to the
normal shift patterns. Towing or driving on long hills
can cause the transaxle uid temperature to be higher
than normal. If the transaxle uid temperature will
not cool, you may need to pull over and check the
transaxle uid level. You should also check the engine
coolant temperature. If it is hot, seeEngine Overheating
on page 5-24.
2-21

Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure your vehicle will not move,
even when you are on fairly level ground, use
the steps that follow. If you are pulling a trailer,
seeTowing a Trailer on page 4-38.
1. Hold the brake pedal down and set the parking
brake.
2. Move the shift lever into the PARK (P) position by
holding in the button on the shift lever and pushing
it all the way toward the front of the vehicle.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) 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
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever away from PARK (P) without rst pushing
the button. If you can, it means that the shift lever
was not fully locked into PARK (P).

For vehicles equipped with all-wheel-drive, this light
will come on and stay on when the all-wheel-drive
system is unable to protect for overheating under
extended heavy all-wheel-drive usage.
If there is an engine-related and brake system
problem that is specically related to traction control,
the traction control system will turn off and the
warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Low Traction Light
If your vehicle has
the Traction Control
System (TCS) and has
front-wheel-drive, this light
will come on when the
system is limiting
wheel spin.
If your vehicle has all-wheel-drive, this light will come on
when the all-wheel-drive system is protecting itself from
overheating due to extended heavy all wheel drive usage.You may feel or hear the system working, but this is
normal. The roads may be slippery if this light comes on.
Adjust your driving accordingly.
The light will stay on for a few seconds after the system
stops limiting wheel spin. This light should also come
on for a few seconds when you start your vehicle.
If it does not, have your vehicle serviced.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine has overheated.
If this happens you should pull over and turn off the
engine as soon as possible. SeeEngine Overheating on
page 5-24for more information.
Notice:Driving with the engine coolant temperature
warning light on could cause your vehicle to
overheat. SeeEngine Overheating on page 5-24.
Your vehicle could be damaged, and it might not be
covered by your warranty. Never drive with the
engine coolant temperature warning light on.
3-30

This light will also come on when starting your vehicle.
If it doesn’t, have your vehicle serviced.
This light will ash when the transaxle has overheated.
See “Transaxle Overheating”, underAutomatic
Transaxle Operation on page 2-19, for more information.
Engine Coolant Temperature Gage
This gage measures the
temperature of the
vehicle’s engine.
If the indicator needle moves into the shaded area, the
engine is too hot. A temperature indicator light will
turn on.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator
light comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which monitors
operation of the fuel,
ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that
may not be covered by your warranty.
3-31

All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver. If the front drive wheels begin
to slip, the rear wheels will automatically begin to
drive the vehicle as required. There may be a slight
engagement noise during hard use but this is normal.
This light will come on
when engine torque is
reduced to protect the
AWD system from
overheating. You may feel
or hear a change in engine
output, but this is normal.
During heavy AWD applications, the engine torque
may be reduced to protect AWD system components.
If the vehicle is exposed to extended heavy AWD usage,
the AWD system will shut itself off to protect the
system from overheating. When the system cools down,
the AWD system will activate itself again automatically;
this cool-down can take up to 20 minutes depending on
outside temperature and vehicle use.
If the AWD system is unable to protect the system
from overheating, the traction off light will come on to
indicate no protection capability. If this light comes
on, take your vehicle in for service.
Steering
Electric Power Steering
If the engine stalls while you are driving, the power
steering assist system will continue to operate until
you are able to stop your vehicle. If you lose power
steering assist because the electric power steering
system is not functioning, you can steer, but it will take
more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time,
you may notice a reduced amount of power steering
assist. The normal amount of power steering assist
should return shortly after a few normal steering
movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems, such as abnormally high steering effort for
a prolonged period of time, contact your dealer for
service repairs.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get
and it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost all
the way to preserve the heat. Start the engine again and
repeat this only when you feel really uncomfortable from
the cold. But do it as little as possible. Preserve the fuel
as long as you can. To help keep warm, you can get out
of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
In order to free your vehicle when it is stuck, you
will need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as rocking
can help you get out when you are stuck, but you
must use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transaxle or other parts of the
vehicle can overheat. That could cause an
engine compartment re or other damage.
When you are stuck, spin the wheels as little
as possible. Do not spin the wheels above
35 mph (55 km/h) as shown on the
speedometer.

Automatic Transaxle Fluid
It is not necessary to check the transaxle uid level.
A transaxle uid leak is the only reason for uid loss.
If a leak occurs, take your vehicle to the dealership
service department and have it repaired as soon
as possible.
Change the uid at the intervals listed inAdditional
Required Services on page 6-6, and be sure to use
the transaxle uid listed inRecommended Fluids and
Lubricants on page 6-12.
Notice:Use of the incorrect automatic transaxle
uid may damage your vehicle, and the damages may
not be covered by your warranty. Always use the
automatic transaxle uid listed inRecommended
Fluids and Lubricants on page 6-12.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 100,000 miles
(166 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating
on page 5-24.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
5-21

What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice:If you use extra inhibitors and/or additives
in your vehicle’s cooling system, you could
damage your vehicle. Use only the proper mixture
of the engine coolant listed in this manual for
the cooling system. SeeRecommended Fluids and
Lubricants on page 6-12for more information.
