2003 Oldsmobile Alero Engine

When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You may hear a momentary motor or clicking noise while
this test
is going on, and you may even notice that
your brake pedal moves or pulses a little. This is normal. Let’s say the road
is wet and you’re driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here’s 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 front wheel
and at both rear wheels.
The anti-lock system 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.

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
also upshift the transaxle to limit wheel spin.

wheel spin. See
Enhanced Traction System
Active Light on page
3-30.
You may feel or hear the system working, but this is
normal.
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 3-7.
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 2-22.

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.

When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.

on the center console.
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 and the indicator light will
go off - 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.

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.

Of course, traction is reduced when water, snow, ice, Driving at Night
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.
If you have the anti-lock braking system, remember: It
helps avoid only the braking skid.
If you do not have
anti-lock, then in a braking skid (where the wheels are
no longer rolling), release enough pressure on the

steering control. Push the brake pedal down steadily Night driving is more dangerous than day driving.

Hydroplaning doesn’t happen often. But it can if your Driving Through Flowing Water
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. Fla
ng or rushi - ater creates strong
forces. If you try to drive through flowing
water, as you might at a low water crossing,
your vehicle can be carried away.
As little as
six inches
of flowing water can carry away a
smaller vehicle. If this happens, you and other
vehicle occupants could drown. Don’t ignore
police warning signs, and otherwise be
very cautious about trying to drive through
flowing water.
Some Other Rainy Weather Tips
e Besides slowing down, allow some extra following
distance. And be especially careful when you
pass another vehicle. Allow yourself more clear
room ahead, and be prepared to have your
view restricted by road spray.
Have good tires with proper tread depth. See Tires
on page 5-53.

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.
Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservior full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a
short time
to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as “highway
hypnosis”? Or is it just plain falling asleep at the wheel?
Call it highway hypnosis, lack of awareness, or
whatever.
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.
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
I ou don’l down, 1 ir brakes cou.-. get
so hot that they wouldn’t work well. You would
then have poor braking or even none going down a
hill. You could crash. Shift down to let
your engine assist your brakes on a steep downhill slope. Coasting downhill in
NEUTRAL
(N) or with the
ignition
off is dangerous. Your brakes will have
to do all the work
of slowing down. They could
get
so hot that they wouldn’t work well. You
would then have poor braking or even none

have your engine running and your vehicle in
gear when you go downhill.

Know how to go uphill. Drive in the highest gear
possible.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or
cut across the center of the road. Drive at speeds
that let you stay in your own lane.
As you go over the top of a hill, be alert. There
could be something in your lane, like
a stalled car or
an accident.
You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling rocks
area or winding roads. Be alert to these and take
appropriate action.

Here are some things to do to summon help and keep
yourself and your passengers safe:
0 Turn on your hazard flashers.
Tie a red cloth to your vehicle 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.
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, especially any that 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.
