CHANGE ENGINE OIL - 82: This means that the life
of the engine oil has expired and it should be changed
within 200 miles. See ªEngine Oilº and ªFilter
Recommendationsº in the Index. After an oil change,
the Oil Life Indicator must be reset. See ªOil Life
Indicator, How to Resetº in the Index.
CHANGE TRANS FLUID
- 47: This message will
appear when it is time to replace the transaxle fluid. See
ªMaintenance Scheduleº in the Index for the proper
fluid and change intervals.
CHECK BRAKE FLUID
- 37: This message will
display if the ignition is in ON to inform the driver that
the brake fluid level is low. Have the brake system
serviced by a technician as soon as possible. See ªBrake
System Warning Lightº in the Index.
CHECK COOLANT LEVEL
- 2: This message
will appear when there is a low level of engine coolant.
Have the cooling system serviced by a technician as
soon as possible.CHECK FUEL GAGE
- 50: (Analog Cluster Only)
This message will appear when the fuel supply is less
than 5 gallons (18.9 L) and the display is turned off.
A single chime will also sound when this message
is displayed.
CHECK GAS CAP
- 61: This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it's on properly.
CHECK OIL LEVEL
- 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message
may appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground with
the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been off
for a few minutes and your vehicle is on a level surface.
Then check the dipstick and add oil if necessary.
See ªEngine Oilº in the Index.

2-106
CHECK WASHER FLUID - 25: This message means
that your vehicle is low on windshield washer fluid.
DRIVER DOOR AJAR
- 140: This message
will display anytime the key is in ON, the transaxle is
not in PARK (P) and the driver's door is open or ajar.
A chime will sound when the vehicle's speed is greater
than 3 mph (4.8 km/h).
DRIVER NO. X (1 OR 2): This message will be
displayed with the key in ON and while entering
FEATURE PROGRAMMING, but only if the vehicle is
equipped with memory seats. The message will show
which driver is activating the personalization feature. It
will only stay on for five seconds. This message can be
customized for you by your dealer.

- 44:
This message will appear when the engine coolant
temperature is over 262
F (128
C). Stop and allow your
vehicle to idle in PARK (P) until it cools down and the
message is removed. Do not increase engine speed
above a normal idle. If it does not cool down, turn off
the engine and have it serviced before driving it again.
Severe engine damage can result from an overheated
engine. See ªEngine Overheatingº in the Index.ENGINE HOT
-AC OFF - 16: 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 will automatically resume.
You can continue to drive your vehicle. If this message
continues to appear, have the system repaired as soon as
possible to avoid compressor damage.
ENGINE OVERHEATED, STOP ENGINE
- 42: This
message will appear when the engine has overheated.
Stop and turn the engine off immediately to avoid
severe engine damage. See ªEngine Overheatingº in
the Index. A multiple chime will also sound when this
message is displayed.
ENGINE POWER REDUCED
- 41: This message
informs you that the vehicle is reducing engine power
because the transaxle is being placed in gear under
conditions that may cause damage to the vehicle's
engine, transaxle or ability to accelerate.
FUEL LEVEL LOW
- 11 : This message serves as a
warning that the fuel level in the tank is critically low.
Stop for fuel soon. A single chime will sound when this
message is displayed.

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.

This warning light will come on to let you know if
there's a problem with your traction control system.
See ªTraction Control System Warning Lightº in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. See ªRocking Your Vehicleº in the Index.
To turn the system off, press
the TRAC ON/OFF button
located on the center
console. (For vehicles with
a column shift lever, the
button is located at the end
of the shift lever.)
The TRACTION OFF message will display on the
Driver Information Center. If the system is limiting
wheel spin when you press the button, the TRACTION
OFF message will display
-- but the system won't turn
off right away. It will wait until there's no longer a
current need to limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The TRACTION READY message
should display briefly on the Driver Information Center.

4-16
A cornering skid is best handled by easing your foot off
the accelerator pedal.
Remember: Any traction control system helps avoid
only the acceleration skid.
If your traction control system is off, then an
acceleration skid is also best handled by easing your
foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
If you have Stabilitrak

, you may see the STABILITY
SYS ENGAGED message on the Driver Information
Center. See ªStability Sys Engaged Messageº in
the Index.Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you'll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your
vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a ªmirrored surfaceº
-- and slow down
when you have any doubt.
Remember: Any anti
-lock brake system (ABS) helps
avoid only the braking skid.

4-20
Hydroplaning doesn't happen often. But it can if your
tires do not have much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or other vehicles, and raindrops ªdimpleº the
water's surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn't a hard and fast rule about hydroplaning.
The best advice is to slow down when it is raining.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine's air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody of your vehicle. If you
can't avoid deep puddles or standing water, drive
through them very slowly.
Driving Through Flowing Water
CAUTION:
Flowing or rushing water creates strong forces. If
you try to drive through flowing water, as you
might at a low water crossing, your vehicle can be
carried away. As little as six inches of flowing
water can carry away a smaller vehicle. If this
happens, you and other vehicle occupants could
drown. Don't ignore police warning signs, and
otherwise be very cautious about trying to drive
through flowing water.
Some Other Rainy Weather Tips

Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.

Have good tires with proper tread depth. See ªTiresº
in the Index.
