The switch stays in this position
when the engine is running. The
transmission is also unlocked in this
position on automatic transmission
vehicles.
If the key is left in the ACC/
ACCESSORY or ON/RUN position
with the engine off, the battery could
be drained. The vehicle may not
start if the battery is allowed to drain
for an extended period of time.
3 (START) :This is the position that
starts the engine. When the engine
starts, release the key. The ignition
switch returns to ON/RUN for
driving.
A warning tone will sound when the
driver door is opened, the ignition is
in ACC/ACCESSORY or LOCK/
OFF, and the key is in the ignition.
Starting the Engine
If the vehicle has a diesel engine,
see the Duramax diesel
supplement.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See Add-On Electrical Equipment
0 272.
Place the transmission in the
proper gear.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Manual Transmission
The shift lever should be in Neutral
and the parking brake engaged.
Hold the clutch pedal down to the
floor and start the engine. The
vehicle will not start if the clutch
pedal is not all the way down.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When
the engine starts, let go of the
key. The idle speed will go
down as the engine gets warm.

222 Driving and Operating
Torque Lock
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of the
vehicle may put too much force on
the parking pawl in the
transmission. You may find it difficult
to pull the shift lever out of P (Park).
This is called torque lock. To
prevent torque lock, set the parking
brake and then shift into P (Park)
properly before you leave the driver
seat. To find out how, seeShifting
Into Park 0221.
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake.
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the parking pawl
in the transmission. You will then be
able to pull the shift lever out of
P (Park).
Shifting out of Park
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is
designed to:
. Prevent ignition key removal
unless the shift lever is in
P (Park).
. Prevent movement of the shift
lever out of P (Park), unless the
ignition is on and the regular
brake pedal is applied.
To shift out of P (Park): 1. Apply the brake pedal.
2. Press the button on the shift lever.
3. Move the shift lever to the desired position.
If you still are unable to shift out of
P (Park):
1. Ease the pressure on the shift lever. 2. While holding down the brake
pedal and pressing the shift
lever button, move the shift
lever all the way into P (Park).
3. While holding the shift lever button, move the shift lever to
the desired position.
If you are still having a problem
shifting, then have the vehicle
serviced soon.
This vehicle may have the Seat Belt
Assurance System, which may
prevent the vehicle from shifting out
of P (Park). See Seat Belts053.
Parking
If the vehicle has a manual
transmission, before you get out of
the vehicle, move the shift lever into
R (Reverse), and firmly apply the
parking brake. Once the shift lever
has been placed into R (Reverse)
with the clutch pedal pressed in,
turn the ignition off, remove the key
and release the clutch.

control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If equipped with a manual
transmission, the cruise control will
remain active when the gears are
shifted. The cruise is deactivated if
the clutch is pressed for several
seconds. If the cruise control is

How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at your dealer. Contact your
dealer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, seeService

Change the fluid and filter at the
intervals listed in Maintenance
Schedule 0365, and be sure to use
the fluid listed in Recommended
Fluids and Lubricants 0374.

How to Check Manual
Transmission Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible. See Recommended
Fluids and Lubricants 0374 for the
proper fluid to use.
Hydraulic Clutch
For vehicles with a manual
transmission, it is not necessary to
regularly check brake/clutch fluid
unless there is a leak suspected.
Adding fluid will not correct a leak.
A fluid loss in this system could
indicate a problem. Have the
system inspected and repaired.
When to Check and What
to Use
The brake/hydraulic clutch fluid
reservoir cap has this symbol on it.
The common brake/clutch fluid
reservoir is filled with DOT 3 brake
fluid as indicated on the reservoir
cap. See Engine Compartment
Overview 0278 for reservoir
location.
How to Check and Add Fluid
Visually check the brake/clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
front of the reservoir. The brake/
hydraulic clutch fluid system should
be closed and sealed.

Warning (Continued)
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
. Stops after high-speed driving.
. Idles for long periods in traffic.
If the overheat warning is displayed
with no sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the
highest fan speed. Open the
windows as necessary. 3. When it is safe to do so, pull off
the road, shift to P (Park) or
N (Neutral), and let the
engine idle.
If the engine coolant temperature
gauge is no longer in the overheat
zone, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
distance from the vehicle in front.
If the warning does not come back
on, continue to drive normally and
have the cooling system checked
for proper fill and function.
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down.
Engine Fan
If the vehicle has a clutched engine
cooling fan, when the clutch is
engaged, the fan spins faster to
provide more air to cool the engine. In most everyday driving conditions,
the fan is spinning slower and the
clutch is not fully engaged. This
improves fuel economy and reduces
fan noise. Under heavy vehicle
loading, trailer towing, and/or high
outside temperatures, the fan speed
increases as the clutch more fully
engages, so an increase in fan
noise may be heard. This is normal
and should not be mistaken as the
transmission slipping or making
extra shifts. It is merely the cooling
system functioning properly. The fan
will slow down when additional
cooling is not required and the
clutch disengages.
This fan noise may also be heard
when starting the engine. It will go
away as the fan clutch partially
disengages.
If the vehicle has electric cooling
fan(s), the fans may be heard
spinning at low speed during most
everyday driving. The fans may turn
off if no cooling is required. Under
heavy vehicle loading, trailer towing,
high outside temperatures,
or operation of the air conditioning

heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the 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 torque
specifications in
Capacities and
Specifications 0379.
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
that brake service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
in many other ways if the wrong
replacement brake parts are
installed or parts are improperly
installed.
Brake Fluid
The brake/clutch master cylinder
reservoir is filled with GM approved
DOT 3 brake fluid as indicated on
the reservoir cap. See Engine
Compartment Overview 0278 for
the location of the reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) or
Neutral with the parking brake
applied if equipped with a manual
transmission. On a level surface,
the brake fluid level should be
between the minimum and
maximum marks on the brake fluid
reservoir.
