Steering
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.
Magnasteer TM
Your vehicle is equipped with GM Magnasteer”, a
steering system that continuously adjusts
the effort you
feel when steering at all vehicle speeds.
It provides ease
when parking yet a firm, solid feel at highway speeds.
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 yo~lr speed. While
you’re
in a curve, speed is the one factor YOLI 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. Unless your traction control
system is on, adding the sudden acceleration can
demand
too much of those places. You can lose control.
What should
Y~LI 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
YOLI’II want to go slower.
If YOLI need to reduce your speed as you approach a
curve, do
it before YOLI enter the curve, while your front
wheels are straight ahead.
Try to adjust YOLI~ 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.

Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over
a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right
in front of you. You can
avoid these problems by braking
-- if you can stop in
time. But sometimes you can't; there isn't room. That's
the time for evasive action
-- steering around the
problem.
Your Aurora can perform very well
in emergencies like
these. First apply your brakes.
It is better to remove as
much speed
as you can from a possible collision. Then
steer around the problem,
to the left or right depending
on the space available.
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 I80 degrees very quickly without removing
either hand.
But you have to act fast, steer quickly, and
just
as quickly straighten the wheel once you have
avoided the object.
The fact that s11ch 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 sometime that your right wheels have
dropped off the edge
of a road onto the shoulder while
you're driving.
If the level of the shoulder 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 1/4 turn until the
right front tire contacts the pavement edge. Then turn
your steering wheel
to go straight down the roadway.

0 Check your mirrors, glance over your shoulder, 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
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle you
just passed
may seem to be farther away from you
than it really is.)
0 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 lights are
not flashing, it may
be slowing down or starting to turn.
0 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.
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
“overdriving” those conditions. But skids are always
possible.
The three types
of skids correspond to your Aurora‘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.
Remember:
Any traction control system helps avoid
only the acceleration skid.

If your traction control system is off, then an
acceleration skid is also 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 yo11 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
surfices 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.
Driving at Night
m
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.

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; OOC) 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.
Keep your traction control system on.
It improves 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. Your
anti-lock brakes improve your ability to make
a
hard stop on a slippery road. Even though you have the
anti-lock braking system, you’ll want to begin stopping
sooner than you would
on dry pavement. See
“Anti-Lock”
in the Index.
Allow greater following distance on any slippery
road.
Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On an
otherwise clear road, ice patches
may appear in
shaded areas where the sun can‘t reach: around
clumps
of trees, behind buildings, or under bridges.
Sometimes the surface
of a curve or an overpass may
remain icy when
the surrounding roads are clear. If
you see
a patch of ice ahead of you, brake before you
are on
it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.

Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road,
you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight
of the
trailer. And always keep
in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lights, tires and mirror adjustment.
If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by Imnd to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your
trip, check occasionally to be sure that the
load is secure, and that the lights and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.
Passing
You'll need more passing distance up ahead when
you're towing a trailer. And, because you're a good deal
longer, you'll need to go much farther beyond the
passed vehicle before
you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move yo~~r
hand to the right. Always back
up slowly and, if
possible. have someone guide you.

When your vehicle is being towed, have the ignition key
off. The steering wheel should be clamped in a
straight-ahead position, with a clamping device
designed for towing service.
Do not use the vehicle’s
steering column lock for this. The transaxle should be
in
NEUTRAL (N) and the parking brake release.
Don’t
have your vehicle towed on the front wheels.
unless you must.
If the vehicle must be towed on the
front wheels, don’t
go more than 35 mph (56 kdh) or
farther than SO miles (80 km) or your transaxle will be
damaged.
If these limits must be exceeded, then the
front wheels have to be supported
on a dolly.
