CHECK TIRE PRESSURE
This message displays when the tire pressure
in one of the tires needs to be checked. This
message also displays LEFT FRONT, RIGHT
FRONT, LEFT REAR, or RIGHT REAR to indicate
which tire needs to be checked. You can receive
more than one tire pressure message at a time.
To read the other messages that may have
been sent at the same time, press the set/reset
button. If a tire pressure message appears on
the DIC, stop as soon as you can. Have the tire
pressures checked and set to those shown on
the Tire Loading Information label. SeeTires on
page 382,Loading Your Vehicle on page 315, and
Ination - Tire Pressure on page 390. The DIC
display also shows the tire pressure values for
the front and rear tires by pressing the vehicle
information button. SeeDIC Operation and
Displays on page 193. If the tire pressure is low,
the low tire pressure warning light comes on.
SeeTire Pressure Light on page 182.
DRIVER DOOR OPEN
This message displays when the driver’s door is
not closed properly. When this message appears,
make sure that the driver’s door is closed
completely.
ENGINE HOT A/C
(Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. To avoid added strain on a hot
engine, the air conditioning compressor is
automatically turned off. When the coolant
temperature returns to normal, the A/C operation
automatically resumes. You can continue to
drive your vehicle.

ENGINE OVERHEATD (Overheated)
IDLE ENGINE
Notice:If you drive your vehicle while the
engine is overheating, severe engine damage
may occur. If an overheat warning appears
on the instrument panel cluster and/or
DIC, stop the vehicle as soon as possible.
Do not increase the engine speed above
normal idling speed. SeeEngine Overheating
on page 355for more information.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle
to idle until it cools down.
ENGINE OVERHEATD (Overheated)
STOP ENGINE
Notice:If you drive your vehicle while the
engine is overheating, severe engine damage
may occur. If an overheat warning appears on
the instrument panel cluster and/or DIC, stop
the vehicle as soon as possible. SeeEngine
Overheating on page 355for more information.This message displays along with a continuous
chime when the engine has overheated. Stop and
turn the engine off immediately to avoid severe
engine damage. SeeEngine Overheating on
page 355.
ENGINE POWER IS REDUCED
This message displays when the vehicle’s engine
power is reduced. Reduced engine power can
affect the vehicle’s ability to accelerate. If this
message is on, but there is no reduction in
performance, proceed to your destination. The
performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a
reduced speed while this message is on, but
acceleration and speed may be reduced. Anytime
this message stays on, the vehicle should be taken
to your dealer for service 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.
Hood Release
To open the hood, do the following:
1. Pull the handle with
this symbol on it. It is
located inside the
vehicle, to the left of
the brake pedal.

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 442, and be sure to
use the transaxle uid listed inRecommended
Fluids and Lubricants on page 448.
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 448.
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
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 355.
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.
352

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. See
Recommended Fluids and Lubricants on
page 448for more information.
353

Checking Coolant
The surge tank is located on the driver’s side
of the engine compartment. SeeEngine
Compartment Overview on page 342for more
information on location.
{CAUTION:
Turning the surge tank pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. Never turn the surge
tank pressure cap — even a little — when
the engine and radiator are hot.
The vehicle must be on a level surface. When
your engine is cold, the coolant level should be
at the COLD FILL line. When your engine is warm,
the level should be at the COLD FILL line or a
little higher.
