Downloaded from www.Manualslib.com manuals search engine DEFROST This setting operates the defroster. Most of the air comes out
near
the windshield, with some going to the floor vents and side window
defrost vents.
Use this when you get fog or ice on the windshield.
HTR (Heater): Most of the air comes out near the floor. The rest comes out
from the defroster vents under the windshield and at
your front side
windows. This is best for cold weather.
VENT The air comes out at the vents on your instrument panel and at your
front side windows.
BI-LEV A/C: With this, outside air comes in through the heater floor vent
and the instrument panel vents. This setting is useful
in cool weather with
bright sunlight.
NORM A/C: This setting cools the outside air. If you first use MAX, use
NORM as soon as the vehicle has cooled down, so outside air will be going
through your vehicle.
MAX A/C: This cools the air the fastest. Move the other lever all the way to
Cold.
MAX lets in only a little air from the outside. You can use MAX at
first when it’s really hot outside and you need to cool off quickly.
NOTICE:
If vehicle is parked with function lever in MAX A/C position
and on an incline with the right side lower than the left, t\
hen water may leak into the passenger compartment in an unusually
heavy rain.
J
OFF: The blower is off, but air still will come from outlets at the front of
your vehicle. The system
will try to keep the air at the chosen temperature.
Engine Coolant Heater (Engine Block Heater)
If you use the optional engine coolant heater before starting your engine,
your heating system
will produce warmer air faster, to heat the passenger
compartment
in cold weather. See “Engine Coolant Heater” in the Index.
Rear Window Defogger
If your vehicle has this option the rear window will have lines running
across the glass. These lines heat your window.
For best results, clear the window
of as much snow or ice as possible first.

Downloaded from www.Manualslib.com manuals search engine Avoid needless heavy braking. Some people drive in spurts - heavy
acceleration followed by heavy braking
- rather than keeping pace with
traffic. This is a mistake. Your brakes may not have time to cool between
hard
stops. Your brakes will wear out much faster if you do a lot of heavy
braking. If
you keep pace with the traffic and allow realistic following
distances, you will eliminate a
lot of unnecessary braking. That means better
braking and longer brake life.
If your engine ever stops while you’re driving, brake normally but don’t
pump your brakes. If
you do, the pedal may get harder to push down. If
your engine stops, you will still have some power brake assist. But you will
use it when you brake. Once the power assist is used up, it may take longer
to stop and the brake pedal will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has an advanced electronic braking system that can help you
keep it under control. When you start your vehicle and begin to drive away,
you may hear
a momentary motor or clicking noise. This is the ABS system
testing
itself.
Here’s how anti-lock works. Let’s say the road is wet. You’re driving safely.
Suddenly
an animal jumps out in front of you.
You slam
on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one of the wheels is
about to stop rolling, the computer will separately work the brakes at each
front wheel and at the rear wheels. The anti-lock system can change the
brake pressure faster than any driver could. The computer
is programmed to
make the most of available tire and road conditions. You can steer around
the obstacle while braking hard.
