Dual Automatic Temperature Control (DATC) system 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, do not drive with the
system OFF, or with recirculated air
engaged and A/C off.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been “aired out”.
•For maximum cooling performance (MAX A/C):
Automatic operation:
•Press AUTO for full automatic operation.
•Do not override A/C or
(recirculated air).
•Set the temperature to 60°F (16°C).
Override operation:
•Select air distribution.
•Select A/C and
(recirculated air). Use(recirculated air)
with A/C to provide colder airflow.
•Set the temperature to 60°F (16°C).
•Set highest fan speed initially, then adjust to maintain comfort.
In
(panel) or(panel/floor) modes:
•Move temperature control to full cold.
•Select A/C and
(recirculated air). Use recirculated air with A/C
to provide colder airflow.
•Set highest fan speed initially, then adjust to maintain comfort.

•To aid in side window defogging/demisting in cold weather:
1. Select
.
2. Select A/C.
3. Adjust the temperature control to maintain comfort.
4. Set the fan speed to the highest setting.
5. 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.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.

The mirror will automatically return to the normal state whenever the
vehicle is placed in R (Reverse) (when the mirror is on) to ensure a
bright clear view when backing up.
Do not block the sensors on the front and back of the inside rear
view mirror since this may impair proper mirror performance.
Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
POWER SIDE VIEW MIRRORS (IF EQUIPPED)
To adjust your mirrors:
1. Rotate the control clockwise to
adjust the right mirror and rotate
the control counterclockwise to
adjust the left mirror.
2. Move the control in the direction
you wish to tilt the mirror.
3. Return to the center position to lock mirrors in place.
The spotter mirror below the main glass (if equipped) must be adjusted
manually.
Heated outside mirrors
(if equipped)
The main mirror glass is heated to
remove ice, mist and fog. To activate
the heated mirrors, press the heated
mirror control (
) located on the
climate control panel. The heated
mirrors will operate for 10 minutes,
then automatically shut off (or shut
off when the engine is turned off).
In cases of extreme ice and cold, the
heater control may need pressing
again after 10 minutes in order to
fully clear the glass. The spotter mirror below the main glass is not heated.
Do not remove ice from the mirrors with a scraper or attempt to
re-adjust the mirror glass if it is frozen in place. These actions
could cause damage to the glass and mirrors.
Fold-away mirrors
Fold the side mirrors in carefully before driving through a narrow space,
like an automatic car wash.

government test course. For example, a tire graded 150 would wear one
and one-half (112) 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.
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. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
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.

The Traction Controlswitch,
located on the instrument panel to
the left of the climate control
system, has an indicator light that
illuminates when the system is off.
The Traction Controlsystem will
automatically turn on every time the
ignition is turned off and on. The
Traction Controlsystem should normally be left on.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the Traction Controlsystem off. This may allow
excess wheel spin to “dig” the vehicle out and enable a successful
“rocking” maneuver.
If a system fault is detected, the traction control active light will
illuminate, the Traction Controlbutton will not turn the system on or
off and your vehicle should be serviced by an authorized dealer.
STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than three to five seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the FULL COLD mark on the dipstick).
•Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your dealer.
•Heavy or uneven efforts may be caused by low power steering fluid.
Check for low power steering pump fluid level before seeking service
by your dealer.
•Do not fill the power steering pump reservoir above the FULL HOT
mark on the dipstick, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
If any steering components are serviced or replaced, install new
fasteners (many are coated with thread adhesive or have prevailing
