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.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However,
if you don’t have anti-lock,
your first reaction
- to hit the brake pedal hard and hold
it down
- may be the wrong thing to do. Your wheels
can stop rolling. Once they do, the vehicle can’t respond
to your steering. Momentum will carry it in whatever
direction it was headed when the wheels stopped rolling.
That could be
off the road, into the very thing you
LAtara tnrinn tn 9 rni VGI G 11 yll ILJ 1W ,\,Id, Gr intG traffic. If
you don’t have anti-lock, use a “squeeze” braking
technique. This will give you maximum braking while
maintaining steering control. You can do this by pushing
on the brake pedal with steadily increasing pressure.
In an emergency, you will probably want
to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease
off the brake pedal.
This will help you retain steering control. If you
do have
anti-lock,
it’s different. See “Anti-Lock Brakes.’’
In many emergencies, steering can help you more than
even the very best braking.
Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction System
(ETS) 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 reduces engine power and may

LOW
TRAC
This light will come on
when your Enhanced
Traction System is limiting
wheel spin. See
Enhanced Traction System
Active Light on page 3-29.
You may feel or hear the system working, but this is
normal. This light will also come on when the anti-lock
brake system is working.
If your vehicle is in cruise control when the enhanced
traction system begins
to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. See “Cruise Control” under
Turn Signal/Multifunction Lever on page 3-6.
The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high
as the shift lever position you’ve
chosen,
so you should use the lower gears only
when necessary. See
Automatic Transaxle Operation on
page
2-24.
TRAC
OFF
When the system is on and the parking brake is
fully released, this warning
light will come on to let
you know
if there’s a
problem.
See
Enhanced Traction System Warning Light on
page 3-28.
When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.

To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can turn the system
off if
you prefer.
To turn the system on or off, press the ETS button on
the instrument panel.
When you turn the system
off, the Enhanced Traction
System warning light will come on and stay on.
If
the Enhanced Traction System is limiting wheel spin
when you press the button
to turn the system off,
the warning light will come on
- but the system won’t
turn
off right away. It will wait until there’s no longer
a current need
to limit wheel spin.
You can turn the system back on at any time by
pressing the button again. The Enhanced Traction
System warning light should go off.
Steering
Power Steerin
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.
4-1 1

An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended
9 and 3 o’clock positions, you
can turn it a
full 180 degrees very quickly without
removing either hand. But you have
to act fast, steer
quickly, and just as quickly straighten the wheel
The fact that such emergency situations are always
possible is a good reason
to practice defensive driving
at all times and wear safety belts properly.

Off-Road Recovery
You may find that your right wheels have dropped off
the edge of a road onto the shoulder while you’re
driving.
!f the !eve! nf the sholrlder is only slightly below the
pavement, recovery should be fairly easy. Ease
off the
accelerator and then,
if there is nothing in the way,
steer
so that your vehicle straddles the edge of
the pavement. You can turn the steering wheel up to
one-quarter turn until the right front tire contacts
tne pavement edge. Then turn your steering wheel
io yo
straight down the roadway.

Driving at Night
I
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
- by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
e
e
e
e
Drive defensively.
Don’t drink and drive.
Adjust your inside rearview mirror
to reduce the
glare from headlamps behind you.
Since you can’t see as well, you may need to slow
down and keep more space between you and other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only
so much road ahead.
In remote areas, watch for animals.
If you’re tired, pull
off the road in a safe place
and rest.

4-1 7

No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as much
light
to see the same thing at night as a 20-year-old.
What you do in the daytime can also affect your
night vision. For example,
if you spend the day in bright
sunshine you are wise
to wear sunglasses. Your
eyes will have less trouble adjusting
to night. But if
you’re driving, don’t wear sunglasses at night. They may
cut down
on glare from headlamps, but they also
make a
lot of things invisible.
You can be temporarily blinded by approaching headlamps.
It can take a second or two, or even several
seconds, for your eyes
to readjust to the dark. When
you are faced with severe glare (as from a driver
who doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps. Keep your
windshield and all the glass on your vehicle
clean
- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep
your eyes moving; that way, it’s easier
to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer from
night blindness
- the inability to see in dim light - and
aren’t even aware of it.
4-1 8

Driving too fast through large water puddles or even
going through some car washes can cause problems,
too. The water may affect your brakes. Try to avoid
puddles. But
if you can’t, try to slow down before you
hit them.
Wet brakes can cause accidents. They won’t
work as well in a quick stop and may cause pulling to one side. You could
lose control of
the vehicle.
After driving through a large puddle of water
or a car wash, apply your brake pedal lightly until your brakes work normally.
Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the
water. This can happen
if the road is wet enough and
you’re going fast enough. When your vehicle is
hydroplaning,
it has little or no contact with the road. Hydroplaning doesn’t
happen often. But it can
if your
tires do not have much tread or
if the pressure in one or
more is low. It can happen
if a lot of water is standing
on the road.
If you can see reflections from trees,
telephone poles or other vehicles, and raindrops
“dimple” the water’s surface, there could be
hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning.
The best advice is
to slow down when it is raining.
Driving Through Deep Standing Water
Notice: If you drive too quickly through deep
puddles or standing water, water can come in
through your engine’s air intake and badly damage
your engine. Never drive through water that is
slightly lower than
the underbody of your vehicle. If
you can’t avoid deep puddles or standing water,
drive through them very slowly.

Here are ways to increase your safety in city driving:
Know the best way to get to where you are
going. Get a city map and plan your trip into
an unknown part of the city
just as you would for a
cross-country trip.
Try to use the freeways that rim and crisscross
most large cities. You’ll save time and energy.
See the next part, “Freeway Driving.”
Treat a green light as a warning signal. A traffic
light is there because the corner
is busy enough
to need it. When a light turns green, and just before
you start
to move, check both ways for vehicles
that have not cleared the intersection
or may
be running the red light.
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.
4-22

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 glance over your shoulder as
often as necessary.
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.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in
trn, ur L‘hl;nrl” en-+ yvul UllIlU spur.
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 is usually posted. 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.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh-such as after a day’s
work-don’t plan to make too many miles that first
part of the journey. Wear comfortable clothing and shoes
you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts
in dealerships all across North America. They’ll be
ready and willing to help
if you need it.

You may want to put winter emergency supplies in
your trunk.
lnrrlulrln In ;fin corqnnr ‘3 rrn~ll hrlrrh 5: hrnnm IIIk.dIUUC/ ut, lrrb duluyb,, u VlllUll U,UY, I u,v..,,n, u
supply of windshield washer fluid, a rag, some winter
outer clothing, a small shovel, a flashlight, a red
cloth and a couple of reflective warning triangles. And,
if
you will be driving under severe conditions, include a
small bag of sand, a piece of old carpet or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet
the road probably have good traction.
However,
if there is snow or ice between your tires and
the road, you can have a very slippery situation.
You’ll have a lot less traction or “grip” and will need to
be very careful.
