2-104
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.

Filling a Portable Fuel Container
CAUTION:
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged if this
occurs. To help avoid injury to you and others:

Dispense gasoline only into
approved containers.

Do not fill a container while it is inside a
vehicle, in a vehicle's trunk, pickup bed or
on any surface other than the ground.

Bring the fill nozzle in contact with the
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.

Don't smoke while pumping gasoline.
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 fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, 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.

Before closing the hood, be sure all filler caps are on
properly. Then pull the hood down and close it firmly.
Underhood Lamp
The underhood lamp will come on when the hood is
opened and the parking lamps are turned on.
Engine Oil
If the CHECK OIL LEVEL message appears on the
instrument cluster, it means you need to check your
engine oil level right away. For more information, see
ªCheck Message, Oil Levelº in the Index.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It's a good idea to check your 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 is
located behind the radiator
on the driver's side of the
vehicle. The handle is a
yellow loop that says
ENGINE OIL on it. For
more information on
location, see ªEngine
Compartment Overviewº in
the Index.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.
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.
