wheel CHEVROLET MALIBU 2007 6.G Owner's Guide

If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the 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.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 344.
Anti-Lock Brake System (ABS)
Your vehicle might have the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
If your vehicle has
ABS, this warning
light on the instrument
panel will come on
briey when you start
your vehicle.Let us say the road is wet and you are driving
safely. Suddenly, an animal jumps out in front of
you. You slam on the brakes and continue braking.
Here is 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
wheel.
293

ABS can change the brake pressure faster than
any driver could. The computer is programmed
to make the most of available tire and road
conditions. This can help you steer around the
obstacle while braking hard.
As you brake, the computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.Remember: ABS does not 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 will
not have time to apply the brakes if that vehicle
suddenly slows or stops. Always leave enough
room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You might feel a slight brake pedal pulsation
or notice some noise, but this is normal.
294

Braking in Emergencies
At some time, nearly every driver gets into a
situation that requires hard braking.
If you have ABS, you can steer and brake at the
same time. However, if you do not have ABS,
your rst reaction — to hit the brake pedal
hard and hold it down — might be the wrong thing
to do. Your wheels can stop rolling. Once they
do, the vehicle cannot 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
were trying to avoid, or into traffic.
If you do not have ABS, 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 ABS, it is
different. SeeAnti-Lock Brake System (ABS)
on page 293.
In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
Your vehicle may have a Traction Control System
(TCS) 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 also upshift
the transmission to limit wheel spin. Also, the
traction control system activates the appropriate
corner brakes to gain even quicker control to
limit wheel spin.
295

This light is located on
the instrument panel
cluster.
It will come on when TCS is limiting wheel spin.
You may feel or hear the system working,
but this is normal.
If your vehicle is in cruise control when the TCS
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. SeeCruise Control on page 176.
The TCS operates in all transmission shift lever
positions except park or neutral. But the system
can upshift the transmission only as high as
the shift lever position you’ve chosen, so you
should use the lower gears only when necessary.
SeeAutomatic Transaxle Operation (Base
Models) on page 124orAutomatic Transaxle
Operation (SS Models) on page 128.This light is located on
the instrument panel
cluster.
When the system is off, this warning light will
come on to let you know if there’s a problem, or if
the system has been turned off.
When the 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 TCS on.
But you can turn the system off if you prefer.
To turn the system on or off, press the TC button
located under the climate controls. In order to
effectively “rock” the vehicle, you will need to
turn off TCS.
If you press the TC button once, the traction
control system will turn off and the TCS warning
light will come on. Press the TC button again
to turn the system back on. The TCS warning
light will go off.
296

When you turn the system off, the TCS warning
light will come on and stay on. If the TCS 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.
Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. SeeAccessories
and Modications on page 344for more
information.
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 also upshift
the transmission to limit wheel spin.This light will come on
when your Enhanced
Traction System is
engaged and limiting
wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the ETS
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. SeeCruise Control on page 176.
The ETS operates in all transmission shift
lever positions. But the system can upshift the
transmission only as high as the shift lever position
you’ve chosen, so you should use the lower
gears only when necessary.
297

When the system is on,
this warning light will
come on to let you know
there’s a problem.
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 ETS on.
But you can turn the system off if you prefer.To turn the system on
or off, press the traction
control button located
on the center console
under the climate
control system.
When you turn the system off, the ETS warning
light will come on and stay on. If the ETS 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 traction control
system warning light should go off.

Steering
Electric Power Steering
If your vehicle has the electric power steering
system and the engine stalls while you are driving,
the power steering assist system will continue to
operate until you are able to stop your vehicle. If
you lose power steering assist because the electric
power steering system is not functioning, you can
steer, but it will take more effort.
If you turn the steering wheel in either direction
several times until it stops, or hold the steering
wheel in the stopped position for an extended
amount of time, you may notice a reduced amount
of power steering assist. The normal amount of
power steering assist should return shortly after
a few normal steering movements.
The electric power steering system does not
require regular maintenance. If you suspect
steering system problems, contact your
dealer/retailer for service repairs. SeeDIC
Warnings and Messages on page 222.
Hydraulic Power Steering
If your vehicle has the hydraulic power steering
system and you lose power steering assist
because the engine stops or the power steering
system is not functioning, you can steer, but it will
take much more effort.
Steering Tips
It is important to take curves at a reasonable
speed.
A lot of the “driver lost control” accidents
mentioned on the news happen on curves.
Here is 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 is no traction, inertia will keep the
vehicle going in the same direction. If you have
ever tried to steer a vehicle on wet ice, you
will understand this.
299

The traction you can get in a curve depends on
the condition of the tires and the road surface,
the angle at which the curve is banked, and your
speed. While you are in a curve, speed is the
one factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. Both
control systems — steering and braking — have
to do their work where the tires meet the road.
Unless you have four-wheel anti-lock brakes,
adding the hard braking can demand too much
of those places. You can lose control.
The same thing can happen if you are steering
through a sharp curve and you suddenly
accelerate. Those two control systems — steering
and acceleration — can overwhelm those places
where the tires meet the road and make you lose
control. SeeTraction Control System (TCS) on
page 295orEnhanced Traction System (ETS)
on page 297.What should you do if this ever happens? Ease
up on the brake or 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 will want
to go slower.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while
the 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.
Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. SeeAccessories
and Modications on page 344.

Steering in Emergencies
There are times when steering can be more
effective than braking. For example, you come
over a hill and nd 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 cannot; there is not room.
That is the time for evasive action — steering
around the problem.
Your vehicle can perform very well in emergencies
like these. First apply the brakes — but, unless
you have anti-lock brakes, not enough to lock the
wheels. SeeBraking on page 292. 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
180 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 such emergency situations are
always possible is a good reason to practice
defensive driving at all times and wear safety
belts properly.
301

Off-Road Recovery
You may nd that your vehicle’s right wheels have
dropped off the edge of a road onto the shoulder
while you are 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 one-quarter turn until the right front
tire contacts the pavement edge. Then turn the
steering wheel to go straight down the roadway.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead,
then goes back into the right lane again. A simple
maneuver?
Not necessarily! Passing another vehicle on a
two-lane highway is a potentially dangerous move,
since the passing vehicle occupies the same
lane as oncoming traffic for several seconds.
A miscalculation, an error in judgment, or a brief
surrender to frustration or anger can suddenly
put the passing driver face to face with the worst
of all traffic accidents — the head-on collision.
