{CAUTION
It can be dangerous to get out
of your vehicle if the shift lever
is not fully in PARK (P) with the
parking brake rmly set. Your
vehicle can roll. Do not leave
your vehicle when the engine is
running unless you have to.
If you have left the engine
running, the vehicle can move
suddenly. You or others could
be injured. To be sure your
vehicle will not move, even
when you are on fairly level
ground, always set the parking
brake and move the shift lever
to PARK (P).
Follow the proper steps to be sure
your vehicle will not move. See
Shifting Into Park (Automatic
Transmission) on page 8-10.
If you are parking on a hill and if
you are pulling a trailer, also
seeTowing a Trailer on page 9-85.
Driving Your Vehicle
Defensive Driving
Defensive driving means “always
expect the unexpected.” The
rst step in driving defensively is to
wear your safety belt, seeSafety
Belts on page 1-5.
{CAUTION
Assume that other road users
(pedestrians, bicyclists, and
other drivers) are going to be
careless and make mistakes.
Anticipate what they might do
and be ready. In addition:
Allow enough following
distance between you and
the driver in front of you.
Focus on the task of driving.
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques
could save your life.
Drunk Driving
{CAUTION
Drinking and then driving is
very dangerous. Your reexes,
perceptions, attentiveness, and
judgment can be affected by
even a small amount of alcohol.
You can have a serious — or
even fatal — collision if you
drive after drinking. Do not
drink and drive or ride with a
driver who has been drinking.
Ride home in a cab; or if you
are with a group, designate a
driver who will not drink.
Death and injury associated with
drinking and driving is a global
tragedy.
Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.

Steering in Emergencies
There are times when steering can
be more effective than braking.
For example, you come over a hill
and nd a truck stopped in your
lane, or a car suddenly pulls
out from nowhere, or a child darts
out from between parked cars
and stops right in front of you.
You can avoid these problems by
braking — if you can stop in time.
But sometimes you cannot; there is
not room. That is the time for
evasive action — steering around
the problem.
Your vehicle can perform very well
in emergencies like these. First
apply the brakes. SeeBraking on
page 8-14. It is better to remove as
much speed as you can from a
possible collision. Then steer around
the problem, to the left or right
depending on the space available.An emergency like this requires close
attention and a quick decision. If you
are holding the steering wheel at the
recommended 9 and 3 o’clock
positions, you can turn it a full
180 degrees very quickly without
removing either hand. But you have
to act fast, steer quickly, and just as
quickly straighten the wheel once
you have avoided the object.
The fact that such emergency
situations are always possible is a
good reason to practice defensive
driving at all times and wear safety
belts properly.
Off-Road Recovery
Your vehicle’s right wheels can
drop off the edge of a road onto the
shoulder while driving.
If the level of the shoulder is only
slightly below the pavement,
recovery should be fairly easy.
Ease off the accelerator and then,
if there is nothing in the way, steer
so that your vehicle straddles the
edge of the pavement. Turn the
steering wheel 3 to 5 inches (about
one-eighth turn) until the right front
tire contacts the pavement edge.
Then turn the steering wheel to go
straight down the roadway.

Accessories and
Modications
When non-dealer/non-retailer
accessories are added to your
vehicle they can affect your vehicle’s
performance and safety, including
such things as, airbags, braking,
stability, ride and handling,
emissions systems, aerodynamics,
durability, and electronic systems
like antilock brakes, traction control
and stability control. Some of

Notice:In cold weather, water
can freeze and crack the engine,
radiator, heater core and other
parts. Use the recommended
coolant and the proper coolant
mixture.
{CAUTION
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene
glycol and it will burn if the
engine parts are hot enough.
Do not spill coolant on a hot
engine.
1. Check the engine coolant
reservoir (A) level and, if
required, top with coolant. See
Engine Coolant on page 9-13.2. Locate the radiator pressure
cap (B).
{CAUTION
Steam and scalding liquids
from a hot cooling system can
blow out and burn you badly.
They are under pressure, and if
you turn the radiator pressure
cap — even a little — they can
(Continued)
CAUTION (Continued)
come out at high speed. Never
turn the cap when the cooling
system, including the radiator
pressure cap, is hot. Wait for
the cooling system and radiator
pressure cap to cool if you ever
have to turn the pressure cap.
3. Cover the cap with a thick
cloth and turn it slowly
counterclockwise and remove.
4. If there is no coolant or the level
is low, slowly ll the system
through the radiator pressure cap
opening with a 50/50 mixture
of clean, drinkable water and
a DEX-COOL
®coolant until full.
Wait 30 seconds for coolant
to settle and top off if the
level drops.
Do not spill coolant on the
accessory drive belts.
If a spill occurs, rinse the belt
with fresh water.

GM’s exclusive TPC Spec system
considers over a dozen critical
specications that impact the overall
performance of your vehicle,
including brake system performance,
ride and handling, traction control,
and tire pressure monitoring
performance. GM’s TPC Spec
number is molded onto the tire’s
sidewall near the tire size. If the tires
have an all-season tread design,
the TPC Spec number will be
followed by an MS for mud and
snow. SeeTire Sidewall Labeling on
page 9-40for additional information.
GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires will
help keep your vehicle performing
most like it did when the tires
were new. Replacing less than a full
set of tires can affect the braking
and handling performance of
your vehicle. SeeTire Inspection
and Rotation on page 9-54for
information on proper tire rotation.{CAUTION
Mixing tires could cause you
to lose control while driving.
If you mix tires of different
sizes, brands, or types
(radial and bias-belted tires),
the vehicle may not handle
properly, and you could
have a crash. Using tires of
different sizes, brands, or
types may also cause
damage to the vehicle. Be
sure to use the correct size,
brand, and type of tires on
all wheels. It is all right to
drive with the compact
spare temporarily, as it was
developed for use on the
vehicle. SeeCompact Spare
Tire on page 9-79.{CAUTION
If you use bias-ply tires on
the vehicle, the wheel rim
anges could develop
cracks after many miles of
driving. A tire and/or wheel
could fail suddenly, causing
a crash. Use only radial-ply
tires with the wheels on the
vehicle.
If you must replace your vehicle’s
tires with those that do not have
a TPC Spec number, make
sure they are the same size, load
range, speed rating, and
construction type (radial and
bias-belted tires) as your vehicle’s
original tires.
