Engine Coolant Heater
Your vehicle may have an engine coolant heater.
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 electrical cord is located on the
driver’s side of the engine compartment.
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.

The Head-Up Display also displays a CHECK
GAGES message. The following messages could
appear on the instrument panel cluster when
CHECK GAGES appears:
Engine Coolant Temperature Warning. See
Engine Coolant Temperature Warning
Message on page 227.
Low Oil Pressure. SeeLow Oil Pressure
Message on page 229.
Charging System Indicator. SeeCharging
System Indicator Message on page 228.
Low Brake Fluid Warning. SeeLow Brake
Fluid Warning Message on page 232.
Under warning conditions, the CHECK GAGES
message will illuminate in the HUD. Look at
the instrument panel cluster for more information.Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance
and damage your vehicle. Do not use the HUD
image as a parking aid.
The HUD controls are
located to the left of the
steering wheel on the
instrument panel.
When the HUD is on, the speedometer reading will
always be displayed. The current audio system
information will only be displayed for three seconds
after the radio, tape or CD track status changes.
This will happen whenever one of the radio controls
is pressed, either on the radio or on the audio
steering wheel controls, if equipped.

Your vehicle may have a Traction Control System
(TCS) warning light. The TCS warning light
may come on for the following reasons:
If you turn the TCS off by pressing the TRAC
OFF button located in the instrument panel
switchbank the TCS warning light will come on
and stay on. To turn the system back on,
press the button again. The TCS warning light
should go off. SeeTraction Control System
(TCS) on page 310for more information.
If there is an engine-related and brake system
problem that is specically related to traction
control, the TCS will turn off and the TCS
warning light will come on.
If the TCS warning light comes on and stays on
for an extended period of time when the system is
turned on, your vehicle needs service.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves near the “H”, your
engine is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under
normal driving conditions, you should pull off the
road, stop your vehicle and turn off the engine
as soon as possible.
SeeEngine Overheating on page 378.

Traction Active Message
If your vehicle has the Traction Control System
(TCS), the TRACTION ACTIVE message will
appear when the TCS is limiting wheel spin. You
may feel or hear the system working, but this
is normal.
Slippery road conditions may exist if this message
appears, so adjust your driving accordingly.
This message will stay on for a few seconds after
the TCS stops limiting wheel spin.
Engine Coolant Temperature
Warning Message
This message will come on when your engine gets
too hot.
If this message comes on, it means that your
engine coolant has overheated. If you have been
operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as
possible.

Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools
away from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.

Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 364
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

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 5 years or
150,000 miles (240 000 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 378.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 messages 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.
