HEATER ONLY SYSTEM
(IF EQUIPPED)
1.Fan speed adjustment:
Controls the volume of air
circulated in the vehicle.
2.Temperature selection:
Controls the temperature of the
airflow in the vehicle.
3.Air flow selections:Controls the direction of the airflow in the
vehicle. See the following for a brief description on each control.
:Distributes outside air through the instrument panel vents.
OFF:Outside air is shut out and the fan will not operate.
:Distributes outside air through the instrument panel vents and the
floor vents.
:Distributes outside air through the floor vents.
:Distributes outside air through the windshield defroster vents and
floor vents.
:Distributes outside air through the windshield defroster vents.
Operating tips
•To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•To reduce humidity build up inside the vehicle during cold or warm
weather, do not drive with the air flow selector in the OFF position.
•Under normal weather conditions, do not leave the air flow selector in
OFF when the vehicle is parked. This allows the vehicle to “breathe”
using the outside air inlet vents.
•Do not put objects under the front seats that will interfere with the air
flow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.

To aid in side window defogging/demisting in cold weather:
1. Select
.
2. Adjust the temperature control to maintain comfort.
3. Set the fan speed to the highest setting.
4. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
WARNING: Do not place objects on top of the instrument panel
as these objects may become projectiles in a collision or sudden
stop.

government test course. For example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
NOTE:The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
Temperature A B C
The temperature grades are A (the highest), B, and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 139. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
WARNING: The temperature grade for this tire is established
for a tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buildup and
possible tire failure.
TIRES
Tires are designed to give many thousands of miles of service, but they
must be maintained in order to get the maximum benefit from them.
Glossary of tire terminology
•Tire label:A label showing the OE (Original Equipment) tire sizes,
recommended inflation pressure and the maximum weight the vehicle
can carry.

any tire is under-inflated, carefully drive the vehicle to the nearest
location where air can be added to the tires. Inflate all the tires to the
recommended inflation pressure.
SNOW TIRES AND CHAINS
WARNING: Driving too fast for conditions creates the
possibility of loss of vehicle control. Driving at very high speeds
for extended periods of time may result in damage to vehicle
components.
NOTE:Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use snow tires and chains, it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.
Follow these guidelines when using snow tires and chains:
•Do not use tire chains on aluminum wheels. Chains may chip the
wheels.
•Use only SAE Class S chains.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
Drive cautiously. Ensure you obtain the proper cables or chains
for you vehicle. Test fit the cables or chains before using them in
snow and/or ice. If you hear the cables or chains rub or bang
against the vehicle, stop and retighten them. If this does not
work, remove the cables or chains to prevent vehicle damage.
Have the cables or chains fitted by a professional before
proceeding.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
