CHEVROLET TRAIL BLAZER 2005 1.G Owners Manual

Four-Wheel Drive
If your vehicle has four-wheel drive, you can send your
engine’s driving power 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 2HI (two-wheel high) for most normal
driving conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive 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 for extended periods of time.
Automatic Transfer Case
If your vehicle is equipped
with 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.
2HI (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.
A4WD (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 2HI.
2-27

4HI (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.
4LO (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.
{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 2-31.
NEUTRAL:Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 4-49for more
information.An indicator light in the knob will show you which
position the transfer case is in. The indicator lights will
come on briey when you turn on the ignition and
one will stay on. If the lights do not come on, you should
take your vehicle to your dealer for service. An
indicator light will ash while shifting the transfer case. It
will stay on when the shift is complete. If for some
reason the transfer case cannot make a requested shift,
it will return to the last chosen setting.
If the service four-wheel drive light on the instrument
panel cluster stays on, you should take your vehicle to
your dealer for service. SeeService Four-Wheel
Drive Warning Light on page 3-47for further information.Shifting Into 4HI (Four-Wheel High) or
A4WD (Automatic Four-Wheel Drive)
Turn the knob to 4HI or A4WD. This can be done at any
speed unless you are shifting out of 4LO. The indicator
light will ash while shifting. It will remain on when
the shift is complete.
Shifting Into 2HI (Two-Wheel High)
Turn the knob to 2HI. This can be done at any speed
unless you are shifting out of 4LO.
2-28

Shifting Into 4LO (Four-Wheel Low)
To shift to 4LO, the vehicle’s engine must be running
and the vehicle must be stopped or moving less
than 2 mph (3.2 km/h) with the transmission in
NEUTRAL (N). The preferred method for shifting into
4LO is to have your vehicle moving 1 or 2 mph
(1.6 to 3.2 km/h). Turn the knob to 4LO. You must wait
for the 4LO indicator light to stop ashing and stay
on before shifting the transmission into gear.
If you turn the knob to 4LO when your vehicle is in gear
and/or moving, the 4LO indicator light will ash for
30 seconds and not complete the shift unless your
vehicle is moving less than 2 mph (3.2 km/h) and the
transmission is in NEUTRAL (N). After 30 seconds, the
transfer case will return to the setting last chosen.
Shifting Out of 4LO (Four-Wheel Low)
To shift from 4LO to 4HI, A4WD drive, or 2HI your
vehicle must be stopped or moving less than 2 mph
(3.2 km/h) with the transmission in NEUTRAL (N) and
the engine running. The preferred method for shifting out
of 4LO is to have your vehicle moving 1 or 2 mph
(1.6 to 3.2 km/h). Turn the knob to 4HI, A4WD or 2HI.
You must wait for the 4HI, A4WD, or 2HI indicator
light to stop ashing and stay off before shifting your
transmission into gear.
If the knob is turned to 4HI, A4WD, or 2HI when your
vehicle is in gear and/or moving, the 4HI, A4WD, or 2HI
indicator light will ash for 30 seconds. It will not
complete the shift unless your vehicle is moving less
than 2 mph (3.2 km/h) with the transmission in
NEUTRAL (N).

Parking Brake
To set the parking brake, hold the regular brake pedal
down with your foot and pull up on the parking brake
lever located between the seats. If the ignition is on, the
brake system warning light on the instrument panel
cluster will come on. SeeBrake System Warning Light
on page 3-38.To release the parking brake, hold the regular brake
pedal down. Pull the parking brake lever up 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 4-53.
2-31

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. See
Four-Wheel Drive on page 2-27. Always put the
shift lever fully in PARK (P) with the parking
brake rmly set. If you are pulling a trailer, see
Towing a Trailer on page 4-53.To shift into PARK (P), do the following:
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.
2-32

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 2-27.
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, seeShifting Into
Park (P) on page 2-32.
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).
2-33

Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. SeeAutomatic Transmission
Operation on page 2-24.
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.
2-34

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:
Your exhaust system sounds strange or
different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a collision.
Your vehicle was damaged when driving
over high points on the road or over road
debris.
CAUTION: (Continued)
CAUTION: (Continued)

Repairs were not done correctly.
Your vehicle or exhaust system had been
modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows down to
blow out any CO; and
Have your vehicle xed immediately.
2-35

Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-35.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-37.
{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 your
parking brake and move the shift lever to
PARK (P).
