1997 CHEVROLET BLAZER automatic transmission

Downloaded from www.Manualslib.com manuals search engine To shift into or out of 4LO:
1. The vehicle must be moving less than 3 mph
(4.8
kmh) with the transmission in NEUTRAL (N)
for an automatic transmission. For a manual
transmission, the clutch pedal must be engaged.
The preferred method for shifting into
or out of 4LO
is to have your vehicle moving 1 to 2 mph (1.6 to
3.2 km/h).
2. Press the transfer case shift button and shift in one
continuous motion.
Don't pause in
N SET PARK BRAKE as you shift into
or out
of 4L0, or your gears could clash.
Remember that driving
in 4HI or 4LO may reduce fuel
economy. Also. driving in four-wheel drive on dry
pavement could cause
your tires to wear faster and
make your transfer case harder to shift and reduce
powertrain longevity.
Electronic Transfer Case (U' Equipped)
. . ... If your four-wheel-drive
vehicle has the electronic
transfer case,
the transfer
case switches are above
Use these switches
to shift into and out of four-wheel
drive.
You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is not engaged in
two-wheel drive. When this lamp
is lit, it is about
one-half
as bright as the others.
4HI: This setting engages your front axle to help drive
your vehicle. Use
4HI when you need extra traction, such
as on snowy or icy roads, or in most off-road situations.

Downloaded from www.Manualslib.com manuals search engine 4LO: This setting also engages your front axle to give
you extra traction. You may never need
4LO. It sends
the maximum power
to all four wheels. You might
choose
4LO if you were driving off-road in sand, mud
or deep snow and climbing or descending steep hills.
Indicator lights
in the switches show you which setting
you are
in. The indicator lights will come on briefly when
you
turn on the ignition and one will stay on. If the lights
do not come on, you should take your vehicle in for
service. An indicator light
will flash while shifting. It will
remain illuminated when the shift is completed.
Shifting from 2HI to 4HI
Press and release the 4HI switch. This can be done at
any speed, and the front axle will lock automatically.

and the front axle will unlock automatically.
Shifting from 2HI or JHI to 4LO
To shift tiom ZHI or -!HI to 4L0, the vehicle must be
stopped or mo\fing less than 3 mph (4.8 kmk) with the
transmission
in NEUTRAL (N) in vehicles equipped with
an automatic transmission or the clutch pedal engaged in
vehicles equipped with a manual transmission.
The
preferred method for shifting into 4LO is to have your
vehicle moving
1 to 2 mph (1.6 to 3.2 km/h). Press
and release the
4LO switch. You must wait for the
4LO indicator light to stop flashing and remain
illuminated before shifting your transmission into
gear or releasing the clutch pedal.
If
the 4LO switch is pressed when your vehicle is in
gear and/or moving, the
4LO indicator light will flash
for
30 seconds and not complete the shift unless your
vehicle is moving slower than 3 mph (4.8
kmk) and
the transmission is in
NEUTRAL (N) or the clutch
pedal engaged.
On automatic transmission equipped vehicles,
if your
transfer case does not shift into 4L0, your transmission
indicator switch may require adjustment. With your
transmission in
NEUTRAL (N), press and release the
4LO switch. While the
4LO indicator light is flashing,
shift
your transmission into PARK (P). Wait until the

Running (Automatic Transmission
Models Only)
I A 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 firmly
set. If you have four-wheel
drive with
a manual transfer case shift lever and
your transfer case is in NEUTRAL (N), your
vehicle will
be free to roll, even if your shift lever
is in PARK (P). So be sure the transfer case is in a
drive gear -- not in NEUTRAL (N). And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't 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 firmly set before
you leave it. After
you've moved the shift lever into the
PARK (P)
position, hold the regular brake pedal down. Then, see
if you can move the shift lever away from PARK (P)
without first pulling it toward you (or pressing the
button
on a console shift lever). If you can, it means that
the shift lever wasn't
fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't shift your
transmission
into PARK (PI properly, the weight of the
vehicle may
put too much force on the parlung pawl in the
tr'msmission.
You may find it difficult to pull the shift
Icver 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 find out how, see "Shifting Into PARK (P)" in
the Index.
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).

(Automatic Transmission)
Your vehicle has a brake-transmission shift interlock.
You have
to fully apply your regular brake before you
can shift from PARK (P) when the ignition is in the
RUN position. See “Automatic Transmission Operation”
in the Index.
If
you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear
you want (you must
press the shift lever button if
you have the console
shift lever).
If you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.
Parking Your Vehicle (Manual
Transmission Models Only)
Before you get out of your vehicle, turn off your engine,
put your manual transmission in
REVERSE (R) and
firmly apply the parking brake.
If you have four-wheel drive with a manual transfer case
shift lever,
be sure your transfer case is in a drive gear.
Your vehicle could roll
if it isn’t.

you are parking on a hill, or if your vehicle is pulling
a trailer, see “Towing

Parked (Automatic Transmission)
It’s better not to park with the engine running. But if
ever have
to, here are some things to know.
A CAUTION:
Idling the engine with the air system control
off could allow dangerous exhaust into
your vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in
a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is
a garage. Exhaust 9- with
CO -- can come in easily. NEVER park in a
garage
with the engine running.
Another closed-in place can be a blizzard.
(See “Blizzard” in the Index.)
I A 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 firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine
is
running unless you have to. If you’ve left the
engine running, the vehicle can move suddenly.
You or others could be injured.
To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to PARK
