Climate Controls 8-7
-(Defog):This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor
outlets, and side window vents.
In this mode, the system turns
off recirculation and runs the air
conditioning compressor unless
the outside temperature is close to
freezing. The recirculation mode
cannot be selected while in the
defog mode.
0(Defrost): This mode removes
fog or frost from the windshield
more quickly. Air is directed to the
windshield and side window vents,
with some directed to the floor
vents. In this mode, the system
automatically forces outside air
into the vehicle and runs the air
conditioning compressor unless
the outside temperature is close to
freezing. The recirculation mode
cannot be selected while in the
defrost mode. The passenger temperature
control cannot be activated while in
defrost mode. If the PASS button is
pressed, the button indicator flashes
three times and will not work. If the
passenger temperature buttons are
adjusted, the driver temperature
indicator changes. The passenger
temperature will not be displayed.
If vent, bi-level, or floor mode is
selected again, the climate control
system displays the previous
temperature settings.
Do not drive the vehicle until all the
windows are clear.
#(Air Conditioning):
Press
to turn the air conditioning (A/C)
compressor on and off. An indicator
light comes on to show that the air
conditioning is on. If this button is pressed when the
air conditioning compressor is
unavailable, the indicator flashes
three times and then turns off. If
the air conditioning is on and the
outside temperature drops below a
temperature which is too cool for air
conditioning to be effective, the air
conditioning light turns off to show
that the air conditioning mode has
been canceled.
On hot days, open the windows long
enough to let hot inside air escape.
This helps to reduce the time it
takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
The air conditioning system
removes moisture from the air, so
a small amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.

Manual Mode
Range Selection Mode
(Hydra-Matic®6-Speed
Transmission)
Base Trim Shown (Uplevel Similar)
The vehicle may have a Range
Selection Mode. The Range
Selection Mode helps control the
vehicle's transmission and vehicle
speed while driving down hill or
towing a trailer by letting you select
a desired range of gears.
To use this feature, do the following:
1. Move the shift lever to M (Manual Mode). 2. Press the plus/minus buttons,
located on the steering column
shift lever, to select the desired
range of gears for the current
driving conditions.
When M (Manual Mode) is selected
a number displays next to the M,
indicating the current gear.
This number is the highest gear that
can be used. However, the vehicle
can automatically shift to lower
gears as it adjusts to driving
conditions. This means that all
gears below that number are
available. When 5 (Fifth) is selected,
1 (First) through 5 (Fifth) gears are
automatically shifted by the vehicle,
but 6 (Sixth) cannot be used until
the plus/minus button located on
the steering column lever is used to
change to the gear.
Grade Braking is not available when
Range Selection Mode is active.
See Tow/Haul Mode on page 9‑42.
While using Range Selection Mode,
Cruise Control and the Tow/Haul
Mode can be used. Notice:
Spinning the tires
or holding the vehicle in one
place on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.
Low Traction Mode
If the vehicle has the Hydra-Matic®
6-Speed Automatic Transmission,
it has a Low Traction Mode that
assists in vehicle acceleration when
road conditions are slippery, such
as with ice or snow. While the
vehicle is at a stop, select the
second gear range using Range
Selection Mode. This will limit
torque to the wheels after it detects
wheel slip, preventing the tires from
spinning.

It is possible that, if driving under
the best conditions, the oil life
system might indicate that an
oil change is not necessary for
up to a year. The engine oil and
filter must be changed at least
once a year and, at this time, the
system must be reset. For vehicles
without the CHANGE ENGINE
OIL SOON message, an oil change
is needed when the OIL LIFE
REMAINING percentage is near
0%. Your dealer has trained service
people who will perform this work
and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is
changed.How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. Always reset the
engine oil life to 100% after every oil
change. It will not reset itself. To
reset the system on most vehicles:
1. Display the OIL LIFEREMAINING on the DIC.
If the vehicle does not have
DIC buttons, the vehicle must
be in P (Park) to access this
display. See Driver Information
Center (DIC) on page 5‑28.
2. Press and hold the SET/RESET button on the DIC, or the trip
odometer reset stem if the
vehicle does not have DIC
buttons, for more than
five seconds. The oil life
will change to 100%. On all vehicles, the Engine Oil Life
System can be reset as follows:
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press the accelerator pedal slowly three times within
five seconds.
3. Display the OIL LIFE REMAINING on the DIC. If the
display shows 100%, the system
is reset. See Driver Information
Center (DIC) on page 5‑28.
If the vehicle has a CHANGE
ENGINE OIL SOON message and
it comes back on when the vehicle
is started and/or the OIL LIFE
REMAINING is near 0%, the engine
oil life system has not been reset.
Repeat the procedure.

Vehicle Care 10-103
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Products that remove odors from
the upholstery and clean the glass
can be obtained from your dealer.
Do not clean the vehicle using:
.A knife or any other sharp object
to remove a soil from any interior
surface.
.A stiff brush. It can cause
damage to the interior surfaces.
.Heavy pressure or aggressive
rubbing with a cleaning cloth.
Use of heavy pressure can
damage the interior and does
not improve the effectiveness of
soil removal.
.Laundry detergents or
dishwashing soaps with
degreasers can leave residue
that streaks and attracts dirt. For
liquid cleaners, about 20 drops
per 3.78 L (1 gal) of water is a
good guide. Use only mild,
neutral-pH soaps.
.Too much cleaner that saturates
the upholstery.
.Cleaners that contain solvents
can damage the interior.
Fabric/Carpet
Use a vacuum cleaner with a
soft brush attachment frequently
to remove dust and loose dirt.
A canister vacuum with a beater bar
in the nozzle may only be used on
floor carpet and carpeted floor mats.
For any soil, always try to remove it
first with plain water or club soda.
Before cleaning, gently remove as
much of the soil as possible using
one of the following techniques:
.For liquids: gently blot the
remaining soil with a paper
towel. Allow the soil to absorb
into the paper towel until no
more can be removed.
.For solid dry soils: remove as
much as possible and then
vacuum.To clean:
1. Saturate a lint-free, clean white
cloth with water or club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub toward the
center. Continue cleaning, using
a clean area of the cloth each
time it becomes soiled.
4. Continue to gently rub the soiled area until the cleaning cloth
remains clean.
5. If the soil is not completely removed, use a mild soap
solution and repeat the cleaning
process that was used with plain
water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. When a
commercial upholstery cleaner or
spot lifter is to be used, test a small
hidden area for colorfastness first.
