Switchbanks
Instrument Panel Switchbank
This switchbank is located in the center of the
instrument panel.
The switchbank may include marker lamp defeat, high
idle, traction control, heated mirrors, power take
-off,
rear air suspension, two
-speed axle (electric), exhaust
brake, two
-speed axle (air), differential lock, rear axle
differential lock and inter
-axle differential lock. If your
vehicle does not have some of the features controlled
by these switches, there will be a blank switch marker in
its place.
For more information, see each of these features in
the Index.

2-61 Illuminated Entry
The delayed illumination feature will allow you to enter
or exit your vehicle with the lights on for about 20
seconds, after the door is closed or the ignition is cycled.
Reading Lamps (If Equipped)
If your vehicle has reading lamps, press the button next
to the lamp to turn the lamp on or off.
Mirrors
Inside Rearview Mirror (If Equipped)
Pull the tab under the mirror toward you to reduce glare
from headlamps behind you after dark. Push the tab
away from you to restore the mirror to the daytime
position.
Outside Rearview Mirrors
Adjust the outside rearview mirrors so you can see a
little of the side of your vehicle, and the area beside
your vehicle from a comfortable driving position. Some
mirrors can be folded in to enter narrow passageways.

2-62
Power Outside Rearview Mirrors (If Equipped)
If you have power outside rearview mirrors, they can be
adjusted from inside the vehicle.
The control for this
feature is located on
the driver's door.
Select the mirror you want to move by turning the
switch clockwise to adjust the passenger's side mirror,
or counterclockwise to adjust the driver's side mirror.
The center position is neutral.
Then, adjust the mirror by pressing the outer arrows on
the switch until the mirror is in the desired position.Heated Outside Rearview Mirrors (If Equipped)
If your vehicle has this feature, your outside rearview
mirrors can be defrosted.The switch is for this
feature is located in the
instrument panel
switchbank.
Press the bottom of the switch to turn the heated outside
rearview mirrors on. The switch indicator light will be
come on and stay on whenever the heated outside
rearview mirrors are activated.
Your rear window defogger will also come on each
time this feature is activated. If your vehicle has a rear
window defogger, See ªRear Window Defoggerº in
the index.

2-63 Convex Outside Mirrors
Your vehicle has convex mirrors on the lower quarter of
both the driver's and passenger's side rearview mirrors.
A convex mirror's surface is curved so you can see more
from the driver's seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right or left lane,
you could hit a vehicle. Check your regular
outside mirrors (or your inside mirror, if you
have one) before changing lanes.
Storage Compartments
Your vehicle includes a number of storage
compartments for storage of often
-used items.
Some vehicles have storage areas in the instrument
panel. Use these spaces for items such as gloves or
small books. Another small storage area may be
located overhead. This area can be used to store
your sunglasses.
Some vehicles have a storage area behind the rear seat.
Other models may have more storage areas underneath
the front passenger's bench seat.
All models have storage pockets and cupholders on each
of the doors. Some models may have additional
cupholders in the center floor console.
All models also have storage compartments located
beneath the floorboard on both sides of the vehicle.

Watch for traffic signs, pavement markings and lines.
If you can see a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates it's all right to pass
(providing the road ahead is clear). Never cross a
solid line on your side of the lane or a double
solid line, even if the road seems empty of
approaching traffic.

Do not get too close to the vehicle you want to
pass while you're awaiting an opportunity. For one
thing, following too closely reduces your area of
vision, especially if you're following a larger
vehicle. Also, you won't have adequate space if the
vehicle ahead suddenly slows or stops. Keep back a
reasonable distance.

When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and don't
get too close. Time your move so you will be
increasing speed as the time comes to move into the
other lane. If the way is clear to pass, you will have a
ªrunning startº that more than makes up for the
distance you would lose by dropping back. And if
something happens to cause you to cancel your pass,
you need only slow down and drop back again and
wait for another opportunity.
If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn't trying to
pass you as you pull out to pass the slow vehicle.

Check your mirrors and start your left lane change
signal before moving out of the right lane to pass.
When you are far enough ahead of the passed vehicle
to see its front in your right outside mirror, activate
your right lane change signal and move back into the
right lane. (Remember that if your right outside
mirror is convex, the vehicle you just passed may
seem to be farther away from you than it really is.)

Try not to pass more than one vehicle at a time
on two
-lane roads. Reconsider before passing the
next vehicle.

Don't overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting to turn.

If you're being passed, make it easy for the
following driver to get ahead of you. Perhaps you
can ease a little to the right.

4-15
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.
Skidding
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
ªoverdrivingº 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 is best handled by easing your foot off
the accelerator pedal. If you have the ªTraction Control
System,º remember: It helps avoid only the acceleration
skid. If you do not have this system, or if the system is
off, then an acceleration skid is also best handled by
easing your foot off the accelerator pedal.
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). See ªDiesel Engine Exhaust Brakeº in the Index
for information about using the exhaust brake on
slippery surfaces. 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 ªmirrored surfaceº
-- and
slow down when you have any doubt.

4-22
Freeway Driving
Mile for mile, freeways (also called thruways, parkways,
expressways, turnpikes or superhighways) are the safest
of all roads. But they have their own special rules.
The most important advice on freeway driving is: Keep
up with traffic and keep to the right. Drive at the same
speed most of the other drivers are driving. Too
-fast or
too
-slow driving breaks a smooth traffic flow. Treat the
left lane on a freeway as a passing lane.At the entrance, there is usually a ramp that leads to the
freeway. If you have a clear view of the freeway as you
drive along the entrance ramp, you should begin to
check traffic. Try to determine where you expect to
blend with the flow. Try to merge into the gap at close
to the prevailing speed. Switch on your turn signal,
check your mirrors and try to blend smoothly with
the traffic flow.
Once you are on the freeway, adjust your speed to the
posted limit or to the prevailing rate if it's slower. Stay
in the right lane unless you want to pass. On some
freeways, larger vehicles aren't allowed to use some
lanes. These places usually are well
-marked.
Before changing lanes, check your mirrors. Then use
your turn signal.
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed for cars
-- but not larger vehicles -- is
usually posted. You should go more slowly.

4-23
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Highway Hypnosis
Is there actually such a condition as ªhighway
hypnosisº? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of awareness,
or whatever.
When you drive the vehicle for a long distance, there is
something about an easy stretch of road with the same
scenery, along with the hum of the tires on the road, the
drone of the engine, and the rush of the wind against the
vehicle that can make you sleepy. Don't let it happen to
you! If it does, your vehicle can leave the road in less
than a second, and you could crash and be injured.What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:

Make sure your vehicle is well ventilated, with a
comfortably cool interior.

Keep your eyes moving. Scan the road ahead and to
the sides. Check your mirrors and your instruments
frequently.

If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.

4-29

Tie a red cloth to your mirror arm to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle if any is blocking
your exhaust pipe. And check around again from
time to time to be sure snow doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery (or batteries) charged. You will need a
well
-charged battery (or batteries) to restart the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater run for a while.
