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 your 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 may feel a slight brake pedal pulsation
or notice some noise, but this is normal.
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 — may 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 291.
In many emergencies, steering can help you
more than even the very best braking.

Watch for traffic signs, pavement markings, and
lines. If you can see a sign up ahead that might
indicate a turn or an intersection, delay your
pass. A broken center line usually indicates it is
all right to pass, providing the road ahead is
clear. Never cross a solid line on your side of
the lane or a double solid line, even if the road
seems empty of approaching traffic.
Do not get too close to the vehicle you want to
pass while you are awaiting an opportunity. For
one thing, following too closely reduces your
area of vision, especially if you are following a
larger vehicle. Also, you will not have adequate
space if the vehicle ahead suddenly slows or
stops. Keep back a reasonable distance.
When it looks like a chance to pass is coming
up, start to accelerate but stay in the right lane
and do not get too close. Time your move so
you will be increasing speed as the time comes
to move into the other lane. If the way is clear to
pass, you will have a running start that more
than makes up for the distance you would lose
by dropping back. And if something happens to
cause you to cancel your pass, you need only
slow down and drop back again and wait for
another opportunity.
If other vehicles are lined up to pass a slow
vehicle, wait your turn. But take care that
someone is not trying to pass you as you pull
out to pass the slow vehicle. Remember to
glance over your shoulder and check the
blind spot.
Check your vehicle’s 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 vehicle’s inside
mirror, activate the right lane change signal and
move back into the right lane. Remember that
your vehicle’s passenger side 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.
Do not overtake a slowly moving vehicle too
rapidly. Even though the brake lamps are not
ashing, it may be slowing down or starting
to turn.
If you are being passed, make it easy for the
following driver to get ahead of you. Perhaps
you can ease a little to the right.

Trailering means changes in handling,
acceleration, braking, durability, and fuel
economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That is 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 pulling a trailer.
Load-pulling components such as the engine,
transaxle, wheel assembly, and tires are forced to
work harder against the drag of the added
weight. The engine is required to operate at
relatively higher speeds and under greater loads,
generating extra heat. What is more, the trailer
adds considerably to wind resistance, increasing
the pulling requirements.If You Do Decide To Pull A Trailer
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 legal, not
only where you live but also where you will
be driving. A good source for this information
can be state or provincial police.
Consider using a sway control. Ask a hitch
dealer about sway controls.
Do not tow a trailer at all during the rst
1,000 miles (1 600 km) the vehicle is driven.
The engine, axle or other parts could be
damaged.
Then, during the rst 500 miles (800 km) that
the vehicle tows a trailer, do not drive over
50 mph (80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
Obey speed limit restrictions when towing a
trailer. Do not drive faster than the maximum
posted speed for trailers, or no more than
55 mph (90 km/h), to save wear on the
vehicle’s parts.

If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will
provide easier cold starting and better protection
for the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you will need for
good performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and lter.
This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change
will be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A change engine oil light or, if
your vehicle has the Driver Information Center
(DIC), a CHANGE OIL SOON message will come
on. SeeChange Engine Oil Light on page 195
orDIC Warnings and Messages on page 208.
Change the oil as soon as possible within the next
600 miles (1 000 km). It is possible that, if you
are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, the engine
oil and lter must be changed at least once a
year and at this time the system must be reset.
Your dealer has GM-trained service people
who will perform this work using genuine GM parts
and reset the system. It is also important to
check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since
the last oil change. Remember to reset the oil life
system whenever the oil is changed.
356

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change the engine oil and lter based on vehicle
use. Anytime the oil is changed, reset the system
so it can calculate when the next oil change is
required. If a situation occurs where you change the
oil prior to a change engine oil light or CHANGE OIL
SOON message being turned on, reset the system.
After changing the engine oil, reset the system by
performing the following steps:
Vehicles with Driver Information Center (DIC)
1. Press the option button on the DIC until
ENGINE OIL MONITOR appears on the
DIC screen.
2. Press the set/reset button to reset the
system. The next screen indicates that
the CHANGE OIL SOON message
has been reset.
If the vehicle has the uplevel DIC, when
the gages button is pressed and the
OIL LIFE REMAINING mode appears,
it should read 100 percent OIL LIFE
REMAINING.
3. Turn the key to OFF.
Vehicles without Driver Information
Center (DIC)
1. With the engine off, turn the ignition
key to RUN.
2. Fully press and release the accelerator
pedal slowly three times within
ve seconds.
3. Turn the key to OFF, then start the
vehicle.
If the light or message comes back on when
you start your vehicle, the oil life system has not
reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that
may be unhealthy for your skin and could
even cause cancer. Do not let used oil stay on
your skin for very long. Clean your skin and nails
with soap and water, or a good hand cleaner.
Wash or properly dispose of clothing or rags
containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil
products.

Automatic Transaxle Fluid
When to Check and Change Automatic
Transaxle Fluid
A good time to check the automatic transaxle uid
level is when the engine oil is changed.
Change the uid and lter at the intervals listed
inAdditional Required Services on page 464,
and be sure to use the transaxle uid listed
inRecommended Fluids and Lubricants
on page 470.
How to Check Automatic
Transaxle Fluid
Because this operation can be a little difficult, you
may choose to have this done at the 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 uid can damage
the transaxle. Too much can mean that some of
the uid could come out and fall on hot engine
or exhaust system parts, starting a re. Too
little uid could cause the transaxle to overheat.
Be sure to get an accurate reading if you check
the transaxle uid.

{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
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 rst applied or
lightly applied. This does not mean something is
wrong with your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to GM torque
specications.
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 apply the brakes, with or without
the vehicle moving, your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a 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. Your vehicle was designed and tested
with top-quality GM brake parts. When you replace
parts of your braking system — for example, when
your brake linings wear down and you need new
ones put in — be sure you get new approved
GM replacement parts. If you do not, 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 have come to expect
can change in many other ways if someone puts
in the wrong replacement brake parts.
