Switchbanks
There are two sets of switchbanks located in the front of the
vehicle. The switches will vary with the options that are
on
your vehicle. It is useful to become familiar with them since
they are used frequently while operating the vehicle.
Overhead Console Switchbank
This switchbank is located in the overhead console. The
switches that you may find in this switchbank are the
Interior Lights Override, Power Sliding Door Override,
Power Sliding Door and the Power Rear Quarter
Windows. If your vehicle does not have some of the
options controlled by these switches, there will be a
blank button in
its place.
For more information, please see each of these features
in the Index.
Instrument Panel Switchbank
This switchbank is located in the instrument panel below
the comfort controls. The switches and controls that
you
may find in this switchbank are the Rear Fan Knob,
Rear Window Wipermasher, Fog Lamps and Traction
Control. If your vehicle does not have some of the
options controlled by these switches, there will be a
blank button in its place.
For more information, please see each of these features
in the Index.
If your vehicle is not equipped with the optional rear
climate control system, there will be a storage space in
this switchbank. The rubber mat can be removed for
cleaning. Snap the mat into place after cleaning.

Cruise control can be dangerous where you
can’t drive safely at
a steady speed. So,
don’t use your cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.
If your vehicle
is in cruise control when the optional
traction control system begins
to limit wheel spin, the
cruise control will automatically disengage. (See
“Traction Control System” in the Index.) When road
conditions allow you to safely use
it again, you may turn
the cruise control back on. Setting Cruise Control
- CAUTION:
If you
leave your crulse control switch on when
you’re not using cruise, you might hit a button
and go into cruise when you don’t want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
it.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.

A CAUTION:
Your regular brake system may not be working
properly if the anti-lock brake system warning
light is flashing. Driving with the anti-lock brake
system warning light flashing can lead to an
accident. After you’ve pulled off the road and
stopped carefully, have the vehicle towed
for service.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re driving, stop
as soon as possible and turn
the ignition off. Then start the engine again to reset the
system.
If the light still stays on, or comes on again
while you’re driving, your vehicle needs service.
If the
light is on but not flashing and the regular brake system
warning light isn’t on, you still have brakes, but
you
don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have
it fixed so it will be
ready to warn you if there
is a problem.
Traction Control System Warning Light
(Option)
This warning light should
come on briefly as you start
the engine.
If the warning
light doesn’t come on then,
have
it fixed so it will be
ready
to warn you if there’s
a problem.
If it stays
on, or comes on when you’re driving, there
may be
a problem with your traction control system and
your vehicle may need service. When this warning light
is on,
the system will not limit wheel spin. Adjust your
driving accordingly.

The traction control system warning light may come on
for the following reasons:
If there’s a brake system problem that is specifically
related to traction control, the traction control system
will turn
off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays
on for an extended period of time when the
system
is turned on, your vehicle needs service.
Low Traction Light (Option)
LOW
TRACTION
If your vehicle has the
traction control system,
there will be a
LOW
TRACTION light on the
instrument panel.
When your anti-lock system is adjusting brake pressure
to help avoid a braking skid, or when your traction
control system is limiting wheel spin, the
LOW
TRACTION light will come on. Slippery road
conditions may exist if this light comes on,
so adjust
your driving accordingly. The light will come on and
stay
on for four seconds when your anti-lock system
adjusts brake pressure for less than four seconds or
when your traction control system limits wheel spin for
less than four seconds. Otherwise, the light will
go out
as soon as the anti-lock system
stops adjusting brake
pressure or the traction control system stops limiting
wheel spin.
The
LOW TRACTION light also comes on briefly, as a
bulb check, when the engine is started. If the light
doesn’t come on then, have it fixed
so it will be there to
tell you when
the system is active.

Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and
let anti-lock work for you. You may feel a
slight brake pedal pulsation or notice some noise, but
this is normal.
If your vehicle has the
traction control system, this
LOW light will come on when
your anti-lock system is

Traction Control System (If Equipped)
Your vehicle may have a traction control system that
limits wheel spin. This is especially useful
in slippery
road conditions. The system operates only if it senses
that
one or both of the front wheels are spinning or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine power
to limit wheel spin.
This light will come on
when the traction control
system is limiting wheel
spin. See “Low Traction
Light” in the Index.

You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely
use it again, you may
reengage the cruise control. (See “Cruise Control”
in the Index.)

This light should come
on briefly when you start
the engine.
If it stays
on
or comes on while you
are driving, there’s a
problem with your traction
control system.
See “Traction Control System Warning Light” in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To
limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off
if you ever need to. (You
should turn the system
off if your vehicle ever gets stuck
in sand, mud, ice or snow. See “Rocking Your Vehicle”
in the Index.)

Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the
very best braking.

Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each of us
is subject to
the same laws of physics when driving on curves. The
traction of the tires against the road surface makes
it
possible for the vehicle to change its path when you turn
the front wheels. If there’s no traction, inertia will keep
the vehicle going in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, you’ll understand this.
The traction you can get in a curve depends on the
condition
of your tires and the road surface, the angle at
which the curve
is banked, and your speed. While you’re
in a curve, speed is the one factor you can control. Suppose you’re steering through
a sharp curve. Then you
suddenly accelerate. Both control systems
-- steering and
acceleration
-- have to do their work where the tires meet
the road. Adding the sudden acceleration can demand too
much of those places. You can lose control.
What should you
do if this ever happens? Ease up on the
accelerator pedal, steer the vehicle
the way you want it
to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed.
Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you’ll want to
go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.

Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and
constantly seek an escape route or area of less danger.
In
a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not “overdriving”
those conditions. But skids are always possible.
The three types
of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
aren’t rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid,
too
much throttle causes the driving wheels to spin.
A cornering skid and an acceleration skid are best
handled by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer
the way you want the
vehicle to go.
If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you’ll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause the tires to slide.
You may not realize
the surface is slippery until your
vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a “mirrored surface”
-- and slow
down when you have any doubt.
Remember: Any anti-lock brake system
(ABS) helps
avoid only the braking skid.

What’s the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction
of all. You can get wet ice when it’s about
freezing
(32°F; 0” C) and freezing rain begins to fall.
Try to avoid driving
on wet ice until salt and sand crews
can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
If you have traction control, keep the system on. It will
improve your ability to accelerate when driving on a
slippery road. Even though your vehicle has a traction
control system, you’ll want to slow down and adjust
your driving to the road conditions. See “Traction
Control System” in the Index.
If you don’t have traction control, accelerate gently. Try
not to break the gentle traction.
If you accelerate too
fast, the drive wheels will spin and polish the surface
under the tires even more.

I NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. If your vehicle
has traction control,
you should turn your traction
control system
off. (See “Traction Control System” in
the Index.) Then shift back and forth between
REVERSE (R) and a forward gear, spinning the wheels
as little as possible. Release the accelerator pedal while
you shift, and press lightly on the accelerator pedal
when the transaxle is in gear.
If that doesn’t get you out
after a few tries, you may need to be towed out.
If you
do need to be towed out, see “Towing Your Vehicle” in
the Index.
