Air vents blow warm air on the sidewindows in cold weather. If Floor,Defog, or Defrost modes areselected, a small amount of air willcome from the vents close to thewindow. If the airflow is shut offusing the sliding knobs, warm airwill be directed to the otherinstrument panel vents. This isnormal operation.

Warning (Continued)
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning isdisplayed but no steam can be seenor heard, the problem may not betoo serious. Sometimes the enginecan get a little too hot when thevehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayedwith no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to thehighest temperature and to thehighest fan speed. Open thewindows as necessary.
3. When it is safe to do so, pull offthe road, shift to P (Park) orN(Neutral),andlettheengine idle.
If the engine coolant temperaturegauge is no longer in the overheatzone, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safedistance from the vehicle in front.If the warning does not come backon, continue to drive normally andhave the cooling system checkedfor proper fill and function.
If the warning continues, pull over,stop, and park the vehicleright away.
If there is no sign of steam, idle theengine for three minutes whileparked. If the warning is stilldisplayed, turn off the engine until itcools down.
Engine Fan
If the vehicle has a clutched enginecooling fan, when the clutch isengaged, the fan spins faster toprovide more air to cool the engine.In most everyday driving conditions,the fan is spinning slower and theclutch is not fully engaged. Thisimproves fuel economy and reducesfan noise. Under heavy vehicleloading, trailer towing, and/or highoutside temperatures, the fan speedincreases as the clutch more fullyengages, so an increase in fannoise may be heard. This is normaland should not be mistaken as thetransmission slipping or makingextra shifts. It is merely the coolingsystem functioning properly. The fanwill slow down when additionalcooling is not required and theclutch disengages.
This fan noise may also be heardwhen starting the engine. It will goaway as the fan clutch partiallydisengages.
If the vehicle has electric coolingfan(s), the fans may be heardspinning at low speed during most

everyday driving. The fans may turnoff if no cooling is required. Underheavy vehicle loading, trailer towing,high outside temperatures,or operation of the air conditioningsystem, the fans may change tohigh speed and an increase in fannoise may be heard. This is normaland indicates that the coolingsystem is functioning properly. Thefans will change to low speed whenadditional cooling is no longerrequired.
The electric engine cooling fansmay run after the engine has beenturned. off. This is normal and noservice is required.
Washer Fluid
What to Use
When windshield washer fluid needsto be added, be sure to read themanufacturer's instructions beforeuse. Use a fluid that has sufficientprotection against freezing in anarea where the temperature may fallbelow freezing.
Adding Washer Fluid
Open the cap with the washersymbol on it. Add washer fluid untilthe tank is full. SeeEngineCompartment Overview0283forreservoir location.
Caution
.Do not use washer fluid thatcontains any type of waterrepellent coating. This cancause the wiper blades tochatter or skip.
.Do not use engine coolant(antifreeze) in thewindshield washer. It candamage the windshieldwasher system and paint.

Caution (Continued)
.Do not mix water withready-to-use washer fluid.Water can cause thesolution to freeze anddamage the washer fluidtank and other parts of thewasher system.
.When using concentratedwasher fluid, follow themanufacturer instructions foradding water.
.Fill the washer fluid tankonly three-quarters full whenit is very cold. This allowsfor fluid expansion iffreezing occurs, which coulddamage the tank if it iscompletely full.
Brakes
Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or be

(3) Aspect Ratio:Atwo-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item 3 of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(4) Construction Code:Aletter
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.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio:The relationship
of a tire's height to its width.
Belt:Arubbercoatedlayerof
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire:Apneumatictire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. SeeTire
Pressure0323.
Curb Weight:The weight of a
motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil,
and coolant, but without
passengers and cargo.
DOT Markings:Acodemolded
into the sidewall of a tire
signifying that the tire is in
