1998 Oldsmobile Achieva brake light

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down. If your 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.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
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.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.

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.
Enhanced Traction System
If your vehicle has the optional four-speed automatic
transaxle, it also has 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.
LOW
TRAC
This light will come on
when your Enhanced
Traction System is limiting
wheel spin. See “Enhanced
Traction System Active
Light” in the Index.
You may feel or hear the system working, but this is normal.
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” in the Index.
31 When the system is on and
ETS
OFF
the parking brake is fully
released, this warning light
will come on
to let you
know if there’s a problem
with the system.
See “Enhanced Traction System Warning Light’’ in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
4-9

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 ever need to. (You should turn the system off if your
vehicle ever gets stuck in sand, mud, ice or snow. See
“Rocking Your Vehicle’’ in
the Index.)
To turn the system on or off,
press the button
on the
instrument panel to the left
of the steering column. You
can turn the system back on at any time by pressing
the button again. The Enhanced Traction System
warning light should go off, and the indicator light on
the button should come on.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
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.
Steering Tips
When you turn the system off, the Enhanced Traction
System warning light will come on and stay on, and the
indicator light on the button will go off.
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.
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:

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.
I
/A CAUTION:
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.

2. Get the vehicles close enough so the jumper cables
can reach, but
be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Set the parking brake
firmly on each vehicle. Put an automatic transaxle in
PARK (P) before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet.
Turn off all
lamps that aren’t needed, as well
as radios. This will
avoid
sparks and help save both batteries. In
addition, it could save your radio.
I NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries.
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
5. Find the positive (+) and negative (-) terminals on
each battery.

There are only two reasons why the brake fluid level in the
reservoir might go down. The first is that
the brake fluid
goes down to
an acceptable level during normal brake
lining wear. When new
linings are put in, the fluid level
goes back up. The other reason is that fluid is leaking out
of the brake system.
If it is, you should have your brake
system fxed, since
a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak. If you add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on the brake hydraulic system.
If you have too much brake fluid, it can spill on the
engine. The fluid will burn
if the engine is hot
enough.
You or others could be burned, and your
vehicle could be damaged. Add brake
fluid only
when work
is done on the brake hydraulic system.

When your brake fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light”
in the Index.
What to Add
When you do need brake fluid, use only DOT-3
brake fluid
-- such as Delco Supreme 11 @ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.

Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something
is wrong with
your brakes.
See “CaliperKnuckle Maintenance Inspection” in
Section
7 of this manual under Part C “Periodic
Maintenance Inspections.”
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires
are rotated, inspect
brake pads for wear and evenly torque wheel nuts in
the proper sequence to GM specifications.
Your rear drum brakes don’; have wear indicators, but if
you ever hear a rear brake rubbing noise, have the rear
brake linings inspected immediately. Also, the
rear
brake drums should be removed and inspected each time
the tires
are removed for rotation or changing. When
you have the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.”
Brake Pedal Travel
See your retailer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your disc
brakes adjust for wear.
If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then
-- very carefully -- make
a few moderate brake stops about every
1,000 miles
(1 600 km), so your brakes will adjust properly.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.
