Instrument Cluster Descriptions
1.Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel filler door is located.
2. Speedometer
• Indicates vehicle speed.
3. Tachometer
• Indicates the engine speed in revolutions per minute
(RPM x 1000).
CAUTION!
Do not operate the engine with the tachometer pointer
in the red area. Engine damage will occur.
4. Temperature Gauge
• The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily. •
The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H”, turn the engine off immediately and call an
authorized dealer for service.

Electronic Throttle Control (ETC) Warning Light
Red TelltaleLight What It Means
Electronic Throttle Control (ETC) Warning Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system. If a prob-
lem is detected while the engine is running, the light will either stay on or flash depending on
the nature of the problem. Cycle the ignition when the vehicle is safely and completely stopped
and the transmission is placed in the PARK position. The light should turn off. If the light re-
mains on with the vehicle under power, your vehicle will usually be drivable; however, see an
authorized dealer for service as soon as possible.
If the light continues to flash when the engine vehicle under power, immediate service is re-
quired and you may experience reduced performance, and your vehicle may require towing. The
light will come on when the ignition is placed in the ON/RUN position and remain on briefly as
a bulb check. If the light does not come on during starting, have the system checked by an au-
thorized dealer.
Oil Pressure Warning Light
Red Telltale
Light What It Means
Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop the vehicle
and shut off the engine as soon as possible. A chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected. This light does not indicate how much oil
is in the engine. The engine oil level must be checked under the hood.

reapply if necessary.
372 SERVICING AND MAINTENANCE

Checking Oil Level
To ensure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. The
engine oil level should be checked five minutes after a
warmed up engine has been shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding 1 quart (0.95 liters) of oil when the reading is at the
bottom of the SAFE zone will result in a reading at the top
of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the rear
window washer (if equipped) is shared. The fluid reservoir is
located in the engine compartment. Be sure to check the fluid
level at regular intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze). When refillingthe washer fluid reservoir, take some washer fluid and apply
it to a cloth or towel and wipe clean the wiper blades; this will
help blade performance.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
WARNING!
Commercial windshield washer solvents are flam-
mable. They could ignite and burn you. Care must be
exercised when filling or working around the washer
solution.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.
378 SERVICING AND MAINTENANCE

WARNING!(Continued)
•To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Front/Rear Axle Fluid
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected.
If gear oil leakage is suspected inspect the fluid level. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
Fluid Level Check
Lubricant should be at the bottom edge of the oil fill hole.
Adding Fluid
Add lubricant only at the fill hole and only to the level
specified above.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.

5. Place the gear selector momentarily into each gearposition (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK.
6. Remove the dipstick, wipe it clean and reinsert it until seated.
7. Remove the dipstick again and note the fluid level on both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid if
the actual level is at or above the hole. The fluid level
should be between the HOT (upper) reference holes on
the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube to
bring it to the proper level. Do not overfill.Use ONLY
the specified fluid (refer to Fluids And Lubricants
under “Technical Specifications” for fluid specifica-
tions). After adding any quantity of oil through the
dipstick tube, wait a minimum of two minutes for the oil
to fully drain into the transmission before rechecking
the fluid level. NOTE:
•The holes in the dipstick will be full of fluid if the
actual level is at or above the hole.
• If it is necessary to check the transmission below the
operating temperature, the fluid level should be be-
tween the two COLD (lower) holes on the dipstick
with the fluid at approximately 80°F (27°C). If the fluid
level is correctly established at 80° F (27°C), it should
be between the HOT (upper) reference holes when the
transmission reaches 180° F (82°C). Remember it is best
to check the level at the normal operating temperature.
CAUTION!
If the fluid temperature is below 50°F (10°C) it may not
register on the dipstick. Do not add fluid until the
temperature is elevated enough to produce an accurate
reading. Run the engine at idle, in PARK, to warm the
fluid.
8. Reinstall the engine cover and snap it down securely onto the four mounting studs.
9. Check for leaks. Release the parking brake.
