So here are some tips for passing:
“Drive ahead.” Look down the road, to the sides
and to crossroads for situations that might affect
your passing patterns. If you have any doubt
whatsoever about making a successful pass, wait
for a better time.
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’s 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’re awaiting an opportunity. For
one thing, following too closely reduces your area
of vision, especially
if you’re following a larger
vehicle.
Also, you won’t 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
don’t 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 isn’t
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 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 your right outside mirror is convex.
The vehicle you just passed may seem
to be
farther away from you than it really is.)

Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what
the vehicle trailering capacity is for your vehicle, you
should read the information in “Weight of the Trailer” that
appears later in this section. 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.
Load-pulling components such as the engine, transaxle,
wheel assemblies 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’s more,
the trailer adds considerably to wind resistance,
increasing the pulling requirements.
If You Do Decide To Pull A Trailer
If you do, here are some important points:
0
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’ll be driving.
A good source for
this information can be state or provincial police.
Consider using a sway control. You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during the first
1,000 miles
(1 600 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 km/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.
Obey speed limit restrictions when towing a trailer.
Don’t drive faster than the maximum posted speed
for trailers, or
no more than 55 mph (90 km/h),
to save wear on your vehicle’s parts.
Three important considerations have to do with weight:

As in the chart shown previously, SAE 5W-30 is the
only viscosity grade recommended for your vehicle. You
should look for and use only oils which have the API
Starburst symbol and which are also identified as
SAE 5W-30.
If you cannot find such SAE 5W-30 oils,
you can use an SAE IOW-30 oil which has the API
Starburst symbol,
if it's going to be 0°F (-18°C)
or above. Do not use other viscosity grade oils, such as
SAE
1OW-40 or SAE 2OW-50 under any conditions.
Notice: Use only engine oil with the American
Petroleum Institute Certified For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
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 SAF OW-30 nil Roth will prnvide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for
good performance and engine protection.
When to Change
Life SystemTM) Engine Oil (GM Oil
Your
vehicle has a computer system that lets you know
when to change the engine oil and filter. 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
OIL SOON message will come
on. Change your oil as soon as possible within the
next two times you stop for fuel. 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, your engine oil and filter
must be changed at least once a year and at this time
check your oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5
000 km) since your
last oil change. Remember to reset the oil life system
whenever the

How to Reset the Oil Life System
The GM Oil Life SystemTM calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system
so it can
calculate when the next oil change is required.
If a
situation occurs where you change your oil prior to a
CHANGE OIL SOON message being turned on,
reset the system.
Always reset the engine Oil Life System to
100% after
every oil change. It will not reset itself.
To reset the OIL LIFE reminder, do the following:
1. With the ignition on, press the SELECT right arrow
on the DIC until you enter the OIL mode. The
current OIL LIFE percentage will be displayed.
2. Press and hold the DIC RESET button for about
five seconds. After five seconds, the display will
show OIL LIFE
XXX%. If OIL LIFE XXX% does not
appear on the display after about five seconds,
see your dealer for service. After you release the
DIC RESET button,
OIL LIFE 100% will appear
on the display.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don’t 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.
Used oil can be a threat to the environment.
If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting
it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil.
If you have a
problem properly disposing of your used oil, ask
your dealer, a service station or a local recycling center
for help.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every

more
of these conditions:
In heavy city traffic where the outside temperature

regularly reaches
90°F (32°C) or
higher.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
If you do not use your vehicle under any of these
conditions, change the fluid and filter at

(1 66 000 km).
service.
See
Part A: Scheduled Maintenance Services on
page
6-4 for automatic transaxle fluid change intervals.
How to Check
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 fluid can damage
your transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine or
exhaust system parts, starting a fire.
Too little fluid
could cause the transaxle to overheat.
Be sure
to get an accurate reading
if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
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).
Get the vehicle warmed up by driving about
15 miles
(24 km) when outside temperatures are above
50°F
(10°C). If it's colder than 50°F (lO"C), you may have to
drive longer.

Notice: When adding coolant, it is important that
you use only DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ is added to
the system, premature engine, heater core or
radiator corrosion may result.
In addition, the engine
coolant will require change sooner
-- at 30,000 miles
(50,000 km) or 24 months, whichever occurs first.
Damage caused by the use of coolant other
than DEX-COOL@
is not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half
DEX-COOL@ coolant which won’t damage
aluminum parts.
If you use this coolant mixture,
you don’t need
to add anything else. Adding
a plain water
to your cooling
system can be dangerous. Plain water, or
some other
liquid such as aicohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system
is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you wouldn’t get the overheat warning.
Your engine could catch fire and you or others
could be burned. Use a
50/50 mixture of clean,
drinkable water and DEX-COOL@ coolant.
Notice: If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty. Too much water
in the mixture can freeze
ana crack ihe engine, raiiiaiur, bakr
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice: If you use the proper coolant, you don’t
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.

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 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.
Battery
Your new vehicle comes with a maintenance free
ACDelco@ battery. When it’s time for a new battery, get
one that has the replacement number shown on the
original battery’s label. We recommend an ACDelco
battery.
Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling. The
battery is located under the rear seat cushion. To
access the battery, see
Removing the Rear Seat
Cushion on page 5-95. You don’t need to access the
battery to jump start your vehicle. See
Jump Starting on
page 5-44.
- - ~ttery -.~t isn’t properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage your
rear seat safety belt systems. You may not be
able to see this damage, and the safety belts
might not provide the protection needed in a
crash. If a replacement battery is ever needed,
it must be vented in the same manner as the
original battery. Always make sure that the
vent hose
is properly reattached before
reinstalling the seat cushion.

Check Tire Pressure System
The check tire pressure system can alert you to a large
change in the pressure of one tire. The system won’t
alert you before you drive that a tire is low or flat.
You must begin driving before the system will work
properly.
The
LOW TIRE PRESSURE message will appear on
the Driver Information Center (DIC)
if pressure difference
(low pressure) is detected in one tire. The check tire
pressure system may not alert you
if:
more than one tire is low,
the vehicle is moving faster than 65 mph (105 km/h),
the system is not yet calibrated,
the tire treadwear is uneven,
the compact spare tire is installed,
tire chains are being used, or
the vehicle is being driven on a rough or
frozen road.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service.
Also, see
Anti-Lock Brake System Warning Light on page 3-36.
The check tire pressure system detects differences
in tire rotation speeds that are caused by changes in tire
pressure. The system can alert you about a low
tire
- but it doesn’t replace normal tire maintenance.
See
Tires on page 5-60.
When the LOW TIRE PRESSURE message appears on
the Driver Information Center, you should stop as
soon as you can and check all your tires for damage. If
a tire is flat, see
If a Tire Goes Flat on page 5-70.
Also check the tire pressure in all four tires as soon as
you can. See
Inflation -- Tire Pressure on page 5-60.
Any time you adjust a tire’s pressure or have one
or more tires repaired or replaced, you’ll need to reset
(calibrate) the check tire pressure system. You’ll
also need to reset the system whenever you rotate the
tires, buy new tires and install or remove the compact
spare.
Don’t reset the check tire pressure system without first
correcting the cause of the problem and checking
and adjusting the pressure in all four tires.
If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.
