Air Delivery Mode Control:
Turn the knob clockwise or
counterclockwise to adjust the
airow direction inside the vehicle.
To change the current air delivery
mode, select one of the following:
)(Bi-Level):Air is directed to
the instrument panel and oor
outlets. Cooler air is directed to the
upper outlets and warmer air to
the oor outlets.
Y(Vent):Air is directed to the
instrument panel outlets.
X(Defog):Air is directed to the
windshield and front door windows.
To reduce fogging, press
#to
turn on the air conditioner. The fan
must also be on.
W(Defog/Floor):Air is directed to
the windshield, front door windows,
and oor outlets. To reduce
fogging, press
#to turn on the air
conditioner. The fan must also
be on.
[(Floor):Air is directed to the
oor outlets.
Temperature Control:Turn the
knob clockwise or counterclockwise
to increase or decrease the
temperature inside the vehicle.
Fan Control:Turn the knob
clockwise or counterclockwise to
increase or decrease the fan speed.
The speed settings can be adjusted
between 1 (Low) and 4 (High).
Turn the knob to
Ato turn the fan
off. When the fan is off, the air

Air Conditioning
For vehicles with air conditioning.
#(Air Conditioning):Press
to turn the air conditioning system
on or off. An indicator light comes on
when the air conditioning is on.
The air conditioning can only
be operated if the engine is on and
the fan is running.
When the air conditioning is on the
air is cooled and dehumidied. If
cooling or dehumidication is
not desired, turn off the air
conditioning to save fuel.
On hot days, open the windows
briey to let the hot inside air
escape, then close them. This helps
to reduce the time it takes for the
vehicle to cool down.

For quicker cool down, do the
following:
1. Press
#to turn on the air
conditioning.
2. Select
Ymode.
3. Set the temperature knob to the
coldest temperature.
4. Set the fan knob to 4.
5. Open all vents.
Recirculation
^(Recirculation):Press to
turn the recirculation mode on or off.
An indicator light inside the button
comes on when the recirculation
mode is active. This mode
recirculates air inside the passenger
compartment and prevents outside
air from entering the vehicle.
The quality of the passenger
compartment air may decrease
since the amount of outside
air entering the vehicle is reduced.When the recirculation mode is
used without air conditioning, the air
humidity increases, and the
windows may fog. Avoid using the
recirculation mode during high
periods of humidity or cool outside
temperatures since this may
result in increased window fogging.
If window fogging is experienced,
select the defrost mode.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
The rear window defogger will only
work when the ignition is in
ON/RUN.
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off. An indicator light
inside the button will be lit when
in use.If the vehicle has heated mirrors,
they turn on when the rear window
defogger button is pressed.
Press the button again to turn them
off. For more information, see
Outside Power Mirror(s) on
page 2-12.
The rear window defogger will stay
on for approximately 15 minutes
after the button is pressed, unless
the ignition is turned off.
Notice:Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal or anything
similar to the defogger grid.

Tire Size
The following illustration shows
an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire
:The United States version of
a metric tire sizing system.
The letter P as the rst
character in the tire size
means a passenger vehicle tire
engineered to standards set
by the U.S. Tire and Rim
Association.
(B) Tire Width
:The three-digit
number indicates the tire
section width in millimeters from
sidewall to sidewall.
(C) Aspect Ratio
:A two-digit
number that indicates the tire
height-to-width measurements.For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A letter
code is used to indicate the
type of ply construction in the
tire. The letter R means radial
ply construction; the letter D
means diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Service Description
:These characters represent the
load index and speed rating
of the tire. The load index
represents the load carry
capacity a tire is certied to
carry. The speed rating is the
maximum speed a tire is certied
to carry a load.
Tire Terminology and
Denitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in pounds per square
inch (psi) or kilopascal (kPa).
Accessory Weight
:This means
the combined weight of optional
accessories. Some examples
of optional accessories are,
automatic transmission, power
steering, power brakes, power
windows, power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire’s height to its width.
Belt
:A rubber coated layer of
cords that is located between the
plies and the tread. Cords may
be made from steel or other
reinforcing materials.

Maintenance Footnotes
(a)A fluid loss in any vehicle system
could indicate a problem. Have the
system inspected and repaired
and the fluid level checked. Add fluid
if needed.
(b)If driving regularly under dusty
conditions or in high-polluted
regions, replace the filter at each
engine oil change.
(c)Inspect brake lines and hoses for
proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc
brake pads for wear and rotors for
surface condition. Inspect other
brake parts, including calipers,
parking brake, etc.
(d)Inspect front and rear suspension
and steering system for damaged,
loose, or missing parts or signs of
wear. Inspect power steering cables
for proper hook-up, binding, cracks,
chafing, etc. Inspect power steering
hydraulic lines and hoses for proper
hook-up, binding, leaks, cracks,
chafing, etc.(e)Inspect hoses and have them
replaced if they are cracked,
swollen, or deteriorated. Inspect all
pipes, fittings and clamps; replace
with genuine parts as needed.
To help ensure proper operation,
a pressure test of the cooling system
and pressure cap and cleaning
the outside of the radiator and
air conditioning condenser is
recommended at least once a year.
(f)Inspect wiper blades for wear,
cracking, or contamination.
Clean the windshield and wiper
blades, if contaminated. Replace
wiper blades that are worn or
damaged. See Windshield Wiper
Blade Replacement on page 9-21
and “Windshield and Wiper Blades”
in Exterior Cleaning on page 9-76.
(g)Make sure the safety belt
reminder light and safety belt
assemblies are working properly.
Look for any other loose or
damaged safety belt system parts.
If you see anything that might keep
a safety belt system from doingits job, have it repaired. Have any
torn or frayed safety belts replaced.
Also see Airbag System Check
on page 1-37.
(h)Lubricate all key lock cylinders,
door hinges and latches, hood
hinges and latches, and trunk lid
hinges and latches. More frequent
lubrication may be required
when exposed to a corrosive
environment. Applying silicone
grease on weatherstrips with a clean
cloth will make them last longer,
seal better, and not stick or squeak.
(i)Change automatic transmission
fluid if the vehicle is mainly driven
under one or more of these
conditions:
In heavy city traffic where the
outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi, police,
or delivery service.
