3. In heavy traffic, let the engineidle in N (Neutral) while stopped.
If it is safe to do so, pull off the
road, shift to P (Park) or
N (Neutral) and let the
engine idle.
If the temperature overheat gauge is
no longer in the overheat zone or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down.Engine Fan
This vehicle has a clutched engine
cooling fan. When the clutch is
engaged, the fan spins faster to
provide more air to cool the engine.
In most everyday driving conditions,
the clutch is not engaged. This
improves fuel economy and reduces
fan noise. Under heavy vehicle
loading, trailer towing and/or high
outside temperatures, the fan speed
increases when the clutch engages.
So you may hear an increase in fan
noise. This is normal and should not
be mistaken as the transmission
slipping or making extra shifts. It is
merely the cooling system
functioning properly. The fan will
slow down when additional cooling
is not required and the clutch
disengages.
This fan noise may also be heard
when the engine is started. It will go
away as the fan clutch disengages.
Power Steering Fluid
The power steering fluid reservoir is
located near the front of the engine
compartment, behind the radiator.
See Engine Compartment Overview
on page 10‑6 for reservoir location.
When to Check Power Steering
Fluid
It is not necessary to regularly
check power steering fluid unless
there is a leak suspected in the
system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.

(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 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 psi (pounds per
square inch) or kPa (kilopascal).
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.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire
:A pneumatic tire
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. See Tire Pressure

If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. SeeHazard
Warning Flashers on page 6‑3.
{WARNING
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall on
you or other people. You and they
could be badly injured or even
killed. Find a level place to
change your tire. To help prevent
the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift lever in
P (Park), or shift a manual
transmission to 1 (First) or
R (Reverse).
(Continued)
WARNING (Continued)
3. If you have afour-wheel-drive vehicle, be
sure the transfer case is in a
drive gear –not in
N (Neutral).
4. Turn off the engine and do not restart while the vehicle
is raised.
5. Do not allow passengers to remain in the vehicle.
To be even more certain the
vehicle will not move, put blocks
at the front and rear of the tire
farthest away from the one being
changed. That would be the tire
on the other side, at the opposite
end of the vehicle. When the vehicle has a flat tire (B),
use the following example as a
guide to assist you in the placement
of wheel blocks (A).
A. Wheel Block
B. Flat Tire
The following information explains
how to use the jack and change
a tire.

Notice:Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not
work, and it could damage the
vehicle.
1. Check the other vehicle. It must
have a 12‐volt battery with a
negative ground system.
Notice: Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged.
2. Get the vehicles close enough so the jumper cables can reach,
but be sure the vehicles are not
touching each other. If they are,
it could cause a ground
connection you do not want. You
would not be able to start your vehicle, and the bad grounding
could damage the electrical
systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If you have a four-wheel-drive
vehicle, be sure the transfer
case is not in Neutral.
Notice: If the radio or other
accessories are left on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories when
jump starting the vehicle. 3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
4. Open the hoods and locate the positive (+) and negative (−)
terminal locations on the other
vehicle. Your vehicle has a
remote positive (+) and a remote
negative (−) jump starting
terminal. See Engine
Compartment Overview on
page 10‑6 for more information
on the terminal locations.
