@ 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 if
your right outside mirror
is convex, the vehicle you
just passed may seem to be farther away from you
than it really is.)
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 lamps are not flashing,
it may
be slowing down or starting to turn.
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 vehicle’s
three control systems.
In t.he 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.

Controlling your vehicle is the key to successful
off-road driving. One
of the best ways to control your
vehicle
is to control your speed. Here are some things to
keep in mind. At higher speeds:
you approach things faster and you have less time to
you have less time to react.
scm
the terrain
for obstacles.
you have more vehicle bounce when you drive
over obstacles.
you’ll need more distance for braking, especially
since you’re on an unpaved surface.
When you’re driving off-road, bouncing and
quick changes in direction can easily throw you
out of position. This could cause you to lose
control and crash.
So, whether you’re driving on
or off the road, you and your passengers should
wear safety belts.
Scanning the Terrain
Off-road driving can take you over many different
kinds of terrain.
You need to be familiar with the
terrain and its many different features. Here are some
things to consider.
Surface Conditions. Off-roading can take you over
hard-packed dirt, gravel, rocks, grass, sand, mud,
snow
or ice. Each of these surfxes affects the steering,
acceleration and braking
of your vehicle in different
ways. Depending upon the kind of surface
you are
on, you may experience slipping, sliding, wheel
spinning, delayed acceleration, poor traction and
longer braking distances.
Swfuce Obsrdes. Unseen or hidden obstacles can
be hazardous. A rock, log, hole, rut or bump can
startle you
if you’re not prepared for them. Often these
obstacles are hidden by grass, bushes, snow or even
the rise and fall
of the terrain itself. Here are some
things to consider:
Is the path ahead clear?
0 Will the surfxe texture change abruptly up ahead?
Does the travel take you uphill or downhill? (There’s
more discussion of these subjects later.)
0 Will you have to stop suddenly or change
direction quickly?

NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your
GM dealer
for-important information about towing a trailer
with your vehicle.
Every vehicle is ready for some trailer towing. If yours
was built with trailering options, as many are, it’s ready
for heavier trailers. But trailering is different than just
driving your vehicle by itself. Trailering means changes
in handling, durability and fuel economy. Successful,
safe trailering takes correct equipment, and it has to be
used properly.
That’s the reason for this part. In it are many
time-tested, important trailering tips and safety rules.
Many of these
are important for your safety and that of
your passengers.
So please read this section carefully
before you pull
a trailer.
If You Do Decide To Pull A Trailer
If you do, here are some important points:

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure-
your rig will be lega1,not only where you live but
also where you’ll be driving. A good source for this
information can be state or provincial police.
Consider using a sway control if your trailer will
weigh
4,000 lbs. (1 800 kg) or less. You should
always use a sway control if your trailer will weigh
more than
4,000 lbs. (1 800 kg). You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all‘during the first
500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then; during the first
500 miles (800 km) that you
tow a trailer, don’t drive over
50 mph (80 ktn/h) and
don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at the
heavier loads.

4. Remove all the wheel
nuts and take off the
flat tire.
5. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel. Rust or dirt on the
wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after
a time. The wheel could come
off and cause an accident. When you change
a
wheel, remove any rust or dirt from the places
where the wheel attaches
to the vehicle. In an
emergency, you can use a cloth or a paper towel
to do this; but be sure to use
a scraper or wire
brush
later, if you need to, to get all the rust or
dirt off.
I A CAUTIO^:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall
off, causing a serious accident.

Automatic Transmission Fluid
When to Check a1 C’ -ge
A good time to check your auromarlc transmission fluid
level
is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle’s GVWR is over 8,600 or
if the vehicle is mainly driven under one or more of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If your vehicle’s GVWR is not over 8,600 and you do
not use your vehicle under any of these conditions, the
fluid and filter
do not require changing.
See “Scheduled Maintenance Services’’
in the Index.
How to Check
Because this operation can be a little difficult, you
may choose to have this done at your GM dealership
Service Department. If
you do it yourself,
be sure to follow all the instructions
here, or
you could get a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
i the fluid could come out and fall on hot engine
~ parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which
is 180°F to 200°F (82°C
to 93°C).

Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine
oil
is changed. However, the fluid in your manual
transmission doesn’t require changing.
How to Check
Because this operation can be a little difficult, you
may choose to have this done at your GM dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get
a false reading.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire.
Be
sure to get an accurate reading if you check your
transmission fluid.
II
Check the fluid level only when your engine is off, the
vehicle
is parked on a level place and the transmission
is cool enough for you to rest your fingers on the
transmission case.
Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom of
the filler plug hole.
3. If the fluid level is good, install the plug and be sure
it is fully seated. If the fluid level is low, add more
fluid as described in the next steps.

Rear Axle
When to Chc d Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change
it. See
“Scheduled Maintenance Services”
in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom
of the filler plug hole.

NOTICE: .
Continuing to drive with worn-out brake pads
could result in costly brake repair.
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.
Free movement
of brake calipers and properly torqued
wheel nuts
are necessary to help prevent brake
pulsation. When tires
are rotated, inspect.brake calipers
for movement, brake pads for wear, and evenly torque
wheel nuts in the proper sequence
to GM specifications.
If you have rear drum brakes, they don’t have wear
indicators, but
if you ever hear a rear brake rubbing
noise, have the rear brake linings inspected.
Also, the
rear brake drums should be remoQed and inspected each
time the tires are removed for rotation or changing.
When you have the front brakes replaced, have the rear
brakes inspected,
too. I
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer 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 brake stop, your disc brakes
adjust for wear.
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.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its
many parts have to be
of top quality and work well
together if the vehicle is to have really good braking.
Vehicles we design and test have top-quality
GM brake
parts
in them, as your vehicle does when it is new. When
you replace parts of your braking system -- for example,
when- your brhke linings wear do.wn and you have
to
haye new ones put in -- be sure you get new genuine
GM replacement parts. If you don’t, your brakes may
no longer work properly. For example,
if someone
puts in brake linings that are wrong for your vehicle,
the balance between your front and rear brakes can
change
-- for the worse. The braking performance
you’ve come to expect can change
in many other ways
if someone puts in the wrong replacement brake parts.
