steering BUICK CENTURY 2003 Owner's Guide

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
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 Ð such as enough water, ice or packed snow
on the road to make a ªmirrored surfaceº Ð 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
brakes to get the wheels rolling again. This restores
steering control. Push the brake pedal down steadily
when you have to stop suddenly. As long as the wheels
are rolling, you will have steering control.Driving at Night
Night driving is more dangerous than day driving. One
reason is that some drivers are likely to be impaired Ð by
alcohol or drugs, with night vision problems, or by fatigue.
Here are some tips on night driving.
·Drive defensively.
·Don't drink and drive.
·Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.

What's the worst time for this? ªWet ice.º 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 (32ÉF; 0ÉC) 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.
If your vehicle has the Enhanced Traction System, keep
the system on. It will improve your ability to accelerate
when driving on a slippery road. Even though your
vehicle has this system, you'll want to slow down and
adjust your driving to the road conditions. See
Enhanced
Traction System (ETS) on page 4-10.
Unless you have the anti-lock braking system, you'll
want to brake very gently, too. (If you do have anti-lock,
see
Braking on page 4-6. This system improves your
vehicle's stability when you make a hard stop on a
slippery road.) Whether you have the anti-lock braking
system or not, you'll want to begin stopping sooner than
you would on dry pavement. Without anti-lock brakes,
if you feel your vehicle begin to slide, let up on the
brakes a little. Push the brake pedal down steadily to
get the most traction you can.Remember, unless you have anti-lock, if you brake so
hard that your wheels stop rolling, you'll just slide. Brake
so your wheels always keep rolling and you can still
steer.
·Whatever your braking system, allow greater
following distance on any slippery road.
·Watch for slippery spots. The road might be ®ne
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.

If You Are Stuck: In Sand, Mud, Ice
or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you don't want to spin your
wheels too fast. The method known as ªrockingº²can
help you get out when you're stuck, but you must
use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transaxle or other parts of the
vehicle can overheat. That could cause an
engine compartment ®re or other damage.
When you're stuck, spin the wheels as little as
possible. Don't spin the wheels above 35 mph
(55 km/h) as shown on the speedometer.
Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transaxle back
and forth, you can destroy your transaxle.
See ªRocking Your Vehicle To Get It Out.º
For information about using tire chains on your vehicle,
see
Tire Chains on page 5-66.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. If you have the
Enhanced Traction System, you should turn the
system off. See
Enhanced Traction System (ETS) on
page 4-10. Then shift back and forth between
REVERSE (R) and FIRST (1) or SECOND (2) gear. The
Enhanced Traction System will be turned off in
FIRST (1) or SECOND (2) gear. Spin the wheels as little
as possible. Release the accelerator pedal while you
shift, and press lightly on the accelerator pedal when the
transaxle is in gear. By slowly spinning your wheels in
the forward and reverse directions, you will cause a
rocking motion that may free your vehicle. If that doesn't
get you out after a few tries, you may need to be
towed out. If you do need to be towed out,
see ªTowing Your Vehicleº following.
4-31

Dolly Towing
Your vehicle can be towed using a dolly. To tow your
vehicle using a dolly, follow these steps:
1. Put the front wheels on the dolly.
2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight-ahead
position.
5. Release the parking brake.
Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label is
inside the trunk lid. The label tells you the proper
size, speed rating and recommended in¯ation pressures
for the tires on your vehicle. It also gives you important
information about the number of people that can be
in your vehicle and the total weight you can carry. This
weight is called the vehicle capacity weight and
includes the weight of all occupants, cargo and all
nonfactory-installed options.
4-33

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,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand 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 lamps 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 your
hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with a trailer, make wider turns than
normal. Do this so your trailer won't strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.

Engine Oil
Checking Engine Oil
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick
handle is the yellow loop
located near the front
of the engine. See
Engine
Compartment Overview
on page 5-12
for more
information on location.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil
dipstick might not show the actual level.
5-13

10. Then replace the pressure cap. At any time during
this procedure if coolant begins to ¯ow out of the
®ller neck, reinstall the pressure cap. Be sure
the arrow on the pressure cap lines up like this.
11. Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the COLD mark
when the engine is cold.
Power Steering Fluid
The power steering ¯uid reservoir is located on the
passenger's side of the vehicle at the back of the engine
compartment, and can be identi®ed by the above
graphic on the cap. See
Engine Compartment Overview
on page 5-12for reservoir location.
5-36

When to Check Power Steering Fluid
It is not necessary to regularly check power steering ¯uid
unless you suspect there is a leak in the system or
you hear an unusual noise. A ¯uid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
Turn the key off, let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then
remove the cap again and look at the ¯uid level on the
dipstick.When the engine
compartment is hot, the
level should be at the
H (hot) mark. When
it's cold, the level should
be at the C (cold) mark. If
the ¯uid is at the ADD
mark, you should add ¯uid.
What to Use
To determine what kind of ¯uid to use, seePart D:
Recommended Fluids and Lubricants on page 6-16.
Always use the proper ¯uid. Failure to use the proper
¯uid can cause leaks and damage hoses and seals.
