CHEVROLET TRAIL BLAZER 2007 1.G Owners Manual

To shift to the FIRST (1) position, you must rst
press the large button on the shift handle.
While the button is pressed, move the shifter in
the FIRST (1) position.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only
the accelerator pedal may damage the
transmission. The repair will not be covered by
your warranty. If you are stuck, do not spin
the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
Four-Wheel Drive
If your vehicle has four-wheel drive, the engine’s
driving power can be sent to all four wheels
for extra traction. To get the most satisfaction out
of four-wheel drive, you must be familiar with
its operation. Read the part that follows before
using four-wheel drive. You should use Two-Wheel
High for most normal driving conditions.Notice:Driving on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive
Low for an extended period of time may cause
premature wear on your vehicle’s powertrain.
Do not drive on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive
Low for extended periods of time.
Notice:If you continually drive your vehicle
with the transfer case in AUTO or Four-Wheel
Drive, you could shorten the life of the
transfer case or the Four-Wheel Drive system.
The selector switch should be left in
Two-Wheel Drive High mode. Only use AUTO
and Four-Wheel Drive when you need extra
traction such as in wet or slippery road
conditions.
121

Automatic Transfer Case
If your vehicle has four-wheel drive, the transfer
case knob is located to the right of the steering
wheel on the instrument panel.
Use this knob to shift
into and out of
four-wheel drive
2
m(Two-Wheel High):This setting is for
driving in most street and highway situations.
Your front axle is not engaged in two-wheel drive.
It also provides the best fuel economy.AUTO (Automatic Four-Wheel Drive):This
setting is ideal for use when road conditions are
variable. When driving your vehicle in automatic
four-wheel drive, the front axle is engaged, but the
vehicle’s power is sent to the rear wheels.
When the vehicle senses a loss of traction, the
system will automatically engage four-wheel drive.
Driving in this mode results in slightly lower fuel
economy than Two-Wheel High.
4
m(Four-Wheel High):This setting should be
used when you need extra traction, such as
on snowy or icy roads or in most off-road
situations. This setting also engages your front
axle to help drive your vehicle.
4
n(Four-Wheel Low):This setting also
engages your front axle and delivers extra torque.
It sends maximum power to all four wheels.
You might choose this setting if you are driving
off-road in deep sand, deep mud, and climbing or
descending steep hills.
122

{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or
someone else could be seriously injured.
Be sure to set the parking brake before
placing the transfer case in NEUTRAL.
SeeParking Brake on page 126.
NEUTRAL:Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle.

until you can press in the button at the end of
the lever. Hold the button in as you move
the parking brake lever all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and you must park on a
hill, seeTowing a Trailer on page 368.
126

Shifting Into Park (P)
{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. 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, use
the steps that follow. With four-wheel drive,
your vehicle will be free to roll — even if
your shift lever is in PARK (P) — if your
transfer case is in NEUTRAL. So, be sure
the transfer case is in a drive gear — not in
NEUTRAL. SeeFour-Wheel Drive on
page 121. Always put the shift lever fully in
PARK (P) with the parking brake rmly set.
If you are pulling a trailer, seeTowing a
Trailer on page 368.To shift into PARK (P):
1. Hold the brake pedal down with your foot and
set the parking brake.
2. Move the shift lever into PARK (P) by pressing
the button on the side of the shift lever and
pushing the lever all the way toward the front
of the vehicle.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. You
know your vehicle is in PARK (P) if the key
can be removed from the ignition.
127

Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle
could move suddenly if the shift lever is
not fully in PARK (P) with the parking
brake rmly set.
If you have four-wheel drive, your vehicle
will be free to roll – even if your lever is in
PARK (P) – if your transfer case is in
NEUTRAL. So be sure the transfer case
is in a drive gear – not NEUTRAL.
SeeFour-Wheel Drive on page 121.
And, if you leave the vehicle with the
engine running, it could overheat and
even catch re. You or others could be
injured. Do not leave your vehicle with the
engine running unless you have to.If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. After you have moved the shift lever into
PARK (P), hold the regular brake pedal down.
Then, see if you can move the shift lever
away from PARK (P) without rst pressing the
button on the console shift lever. If you can,
it means that the shift lever was not fully locked
into PARK (P).
Torque Lock
If you are parking on a hill and you do not shift
your transmission into PARK (P) properly,
the weight of the vehicle may put too much force
on the parking pawl in the transmission.
You may nd it difficult to pull the shift lever out
of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you
leave the driver’s seat. To nd out how, see
Shifting Into Park (P) on page 127.
128

When you are ready to drive, move the shift
lever out of PARK (P) 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, so you can pull the shift
lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system. You have to fully apply
the regular brakes rst and then press the shift
lever button before you can shift from PARK (P)
when the ignition is in RUN. SeeAutomatic
Transmission Operation on page 117.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
129

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the
gas carbon monoxide (CO), which you
cannot see or smell. It can cause
unconsciousness and death.
You might have exhaust coming in if:
The exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a
collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when
driving over high points on the road
or over road debris.
