Low Oil Level Light
Your vehicle may have
a low oil level light.
This light should come on as a check, when you
start your engine. If the light fails to come on, have
it repaired as soon as possible so you will be
aware when the oil level is low.
Vehicles that have Caterpillar
®diesel engines may
not have a low oil level light. In this case, the light
will neither come on as a check when you start your
engine, nor will it come on to indicate a low oil level.
If this light comes on and stays on, it means your
engine is low on oil. You need to check the oil level
right away. SeeEngine Oil (Caterpillar
®DieselEngine) on page 268orEngine Oil (Gasoline
Engine) on page 268orEngine Oil (DURAMAX
®/
Isuzu Diesel Engine) on page 272for further
information.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
Change Engine Oil Light
The change engine oil
light should come on
briefly as a bulb
check when you start
the engine. If the
light does not come on,
have it serviced.
If the change engine oil light comes on and stays
on after you start the engine, have the oil
changed.

Transmission Temperature Gage
If you have an automatic
transmission and this
gage, it is located above
the switchbank in the
center of the instrument
panel.
When your ignition is on, the gage shows the
temperature of the transmission oil. A reading in
the warning zone, the red area beginning at 300°F
(150°C), means you must stop driving and
check into the cause. One possible cause is a low
oil level in the transmission.
Notice:If you drive your vehicle with the
transmission temperature gage above normal
operating range, you can damage the
transmission. This could lead to costly repairs
that would not be covered by your warranty.
Do not drive your vehicle while the
transmission temperature gage reading is
above normal. See your dealer for service.
Exhaust Brake Indicator Light
If your vehicle is
equipped with an
exhaust brake, you will
have this light, located
above the climate
controls in the center of
the instrument panel.

Reduced Engine Power Light
If the check engine and
reduced engine power
lights are on, the
electronic throttle control
may be disabled, and a
noticeable change in the
vehicle’s performance
may occur.
If the reduced engine power light is on, but there
is no change in performance, proceed to your
destination. The performance may be reduced the
next time the vehicle is driven. The vehicle may

and speed may be limited.
Anytime the check engine light stays on, the
vehicle should be taken to an authorized dealer as

gage is located above
the switchbank in
the center of the
instrument panel.
This gage shows the air pressure for both your
front and rear brake systems.
If the needle on the gage indicates that the air
pressure is below 60 to 75 psi (415 to 517 kPa),
the low air warning light will come on. An alarm will
also sound if this happens.The top pointer shows the pressure available for the
front system, while the bottom pointer shows
pressure for the rear. There should be no more than
4 psi (28 kPa) difference showing between the
systems.
Don’t drive until both pointers are showing at least
120 psi (827 kPa), so you’ll have enough air if
you need to apply your brakes.
Hourmeter Gage
To access the engine hourmeter gage, press the
trip odometer button three times.
The instrument panel cluster displays the
accumulated engine run time hours using the
reconfigurable odometer display. The engine run
time hours displays only when the ignition is in the
LOCK or ACCESSORY position and the trip
reset button is pressed for about four seconds.
The value of the accumulated hours does
not change when the battery is disconnected.
The hourmeter resets to 0.0 when 10,000 hours
are accumulated. The instrument panel cluster
begins to reaccumulate the engine run time hours
from 0.0 hours.

Care of the Cassette Tape Player
A tape player that is not cleaned regularly
can cause reduced sound quality, ruined cassettes
or a damaged mechanism. Cassette tapes
should be stored in their cases away from
contaminants, direct sunlight and extreme heat.
If they aren’t, they may not operate properly
or may cause failure of the tape player.
The tape player should be cleaned regularly after
every 50 hours of use. The radio may display
CLN to indicate that the tape player has been used
for 50 hours without resetting the tape clean
timer. If this message appears on the display, the
cassette tape player needs to be cleaned. It
will still play tapes, but it should be cleaned as
soon as possible to prevent damage to the tapes
and player. If there is a reduction in sound
quality, try a known good cassette to see if the
tape or the tape player is at fault. If this other
cassette has no improvement in sound quality,
clean the tape player.For best results, use a scrubbing action,
non-abrasive cleaning cassette with pads which
scrub the tape head as the hubs of the cleaner
cassette turn. The recommended cleaning cassette
is available through your dealer.
The cut tape detection feature of the cassette tape
player may identify the cleaning cassette as a
damaged tape. To prevent the cleaning cassette
from being ejected, use the following steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE button for
two seconds until the radio produces
one beep. CAS will flash on the display for
five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the
manufacturer’s recommended cleaning time.
After the cleaning cassette is ejected, the
cut tape detection feature will be active again.
