You will find air outlets in the center and on the sides of
your instrument panel.
You can direct the airflow side
-to-side by rotating the
thumbwheel located in the center of the vent. The vent
can be tilted up and down also. To control the amount
of airflow through the outlets, rotate the thumbwheel
below the vent.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, move the
fan control to the right to the highest setting for a
few moments before driving off. This helps clear the
intake ducts of snow and moisture, and reduces the
chance of fogging the inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

4-3 Vehicle Design
According to the U.S. Department of Transportation,
utility vehicles have a significantly higher rollover rate
than other types of vehicles. Utility vehicles do have a
higher ground clearance and a narrower track or shorter
wheelbase than passenger cars to make them more
capable for off
-road driving. Specific design
characteristics like these give the driver a better view of
the road, but also give utility vehicles a higher center of
gravity than other types of vehicles. This means that you
shouldn't expect a utility vehicle to handle the same way
a vehicle with a lower center of gravity, like a car, would
in similar situations. But driver behavior factors are far
more often the cause of a utility vehicle rollover than are
environmental or vehicle factors. Safe driver behavior
and understanding the environment in which you'll be
driving can help avoid a rollover crash in any type of
vehicle, including utility vehicles.
Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in your
vehicle: Buckle up. (See ªSafety Beltsº in the Index.)Defensive driving really means ªbe ready for anything.º
On city streets, rural roads or freeways, it means
ªalways expect the unexpected.º
Assume that pedestrians or other drivers are going to
be careless and make mistakes. Anticipate what they
might do. Be ready for their mistakes.
Rear
-end collisions are about the most preventable
of accidents. Yet they are common. Allow enough
following distance. It's the best defensive driving
maneuver, in both city and rural driving. You never
know when the vehicle in front of you is going to
brake or turn suddenly.
Defensive driving requires that a driver concentrate on
the driving task. Anything that distracts from the
driving task
-- such as concentrating on a cellular
telephone call, reading, or reaching for something on
the floor
-- makes proper defensive driving more
difficult and can even cause a collision, with resulting
injury. Ask a passenger to help do things like this, or
pull off the road in a safe place to do them yourself.
These simple defensive driving techniques could save
your life.
