1997 GMC JIMMY engine

Automatic Transmission Operation
Your automatic transmission may have a shift lever
located
on the console between the seats or on the
steering column.
There are several different positions for
YOLK shift lever.
If your vehicle is equipped with a column shift lever. it
features an electronic shift position indicator within the
instrument cluster. This display must be powered
anytime the
shift lever is capable of being moved out of-’
the PARK (P) position. This means that if your key is in
the OFF position, but not locked, there will be a snnall
current drain on your battery which could discharge
your battery over a period of time. If you need to leave
your key
in the ignition in the OFF position for an
extended period, it is recommended that you disconnect
the battery cable from the battery to prevent discharging
your battery.
PARK (P): This locks your rear wheels. It’s the best
position to use when
YOLI start your engine because yo~~r
vehicle can’t move easily. It
is 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 have 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
nwve the shift lever to
PARK (P).
If you have 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 (N). So, be sure the transfer case is in
a drive gear, two-wheel high
(2HI) or four-wheel
high
(4HI) or four-wheel low (4LO) -- not in
NEUTRAL (N). See “Shifting Into PARK (P)” in
the Index.
If you’re pulling a trailer, see “Towing
a Trailer” in the Index.

E11~~11-e the shift lever is f~~lly in PARK (P) range before
starting
the engine. Your vehicle has a brake-transmission
shift interlock. You have to
fully apply your regular brakes
before
you can shift from PARK (P) when the ignition
key is
in the RUN position. If you cannot shift out of
PARK (P), ease pressure on the shift lever -- push the shift
lever all
the way into PARK (P) (press the button in on the
console shift lever)
as you maintain brake application.
Then n~ove the
shift lever into the gear you wish. See
“Shifting Out of PARK
(P)“ in the Index.
REVERSE (R): Use
this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle
is moving forward could damage your
transmission. Shift
to REVERSE (R) only
after your vehicle
is stopped.
To rock yo~~r vehicle back and forth to get out of snow.
ice or
sand without damaging your transmission, see
”Stuck:
In Sand, Mud. Ice or Snow“ in the Index. NEUTRAL
(N): In this position, your engine doesn’t
connect
with the wheels. To restart when you’re already
moving. use NEUTRAL
(N) only.
Shifting out of PARK
(P) or NEUTRAL (N) while
your engine is “racing” (running at high speed)
is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people or
ob-jects. Don’t shift out of PARK
(P) or
NEUTRAL (N) while your engine is racing.
I NOTICE:
Damage to your transmission caused by shifting
out of PARK
(P) or NEUTRAL (N) with the
engine racing isn’t covered by your warranty.
2-19

NEUTRAL (N): Use this position when you start or
idle your engine.
REVERSE (R): To back up, press the clutch pedal, wait
about six seconds, then shift into
REVERSE (R). Then
let
up on the clutch pedal slowly while pressing the
accelerator pedal.
I NOTICE:
Shift to REVERSE (R) only after your vehicle
is stopped. Shifting to REVERSE
(R) while
your vehicle
is moving could damage
your transmission.
Use REVERSE (R), along with the parking brake. for
parking your vehicle.
Shift Light
SHIFT
If you have a manual
transmission. you have a
SHIFT light.
This light
will show you when to shift to the next higher
gear for best fuel economy.
When this
light comes on, you can shift to the next
higher gear
if weather, road and traffic conditions let
you. For the best fuel economy, accelerate slowly
and
shift when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the
SHIFT light when you downshift.
2-22

If’ you skip more than one gear when you
downshift, you could lose control
of your vehicle.
And you could injure yourself or others. Don’t shift
down more than one gear when
you downshift.
If your vehicle has four-wheel drive and is equipped
with a manual transmission. disregard the shift light
wlxn the transfer case is in 4LO.
Locking Rear Axle
If you have this feature. your rear axle can give you
additional traction
on sno\v, mud. ice, sand 01- gra~~l. It
works like a standard axle most of the time, but when
one of the rear nhxls has
no traction and the other does,
the locking feature
will allow the wheel with traction to
~nove the vehicle.
All-Wheel Drive (If Equipped)
If your \:chicle has all-wheel drive, your engine’s
driving power is sent to all four wheels for extra
traction. This is like four-wheel drive, but there is
no
lever or switch to engage or disengage the front axle.
It is fully automatic and adjwts itself as needed for
mid conditions.
Four-wheel Drive (If Equipped)
If your vehicle has four-wheel drive, you can send your
engine’s driving power
to all four wheels for extra
traction.
To shift out of two-wheel drive and into
four-wheel drive, move the transfer case shift lever to
4HI or 4LO. You should use ?HI for most normal
driving conditions.
1 NOTICE:
~~ ~~~~~ ~~ ~~~~
Driving in the 4HI or 41,O positions for a long
time on
dry or wet pavement could shorten the
life of your vehicle’s drivetrain.

Shifting Into PARK (P) (Automatic
Transmission
Models Only)
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.
If you have 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, use the steps that
follow. 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). If you’re pulling a trailer, see
“Towing a Trailer” in the Index.
Column Shift Lever
1. Hold the brake pedal down with your right foot and
set the parking brakc.
2. Move the shift lever into PARK (P) position like this:
2-30

Leaving Your Vehicle With the Engine
Running (Automatic Transmission
Models Only)
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move suddenlJ
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 yo~~r 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 YOLI 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
(P) 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 PARK (P). This is called "torque lock." To
prevent torque lock, set the parking br'ke 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) kc$~w 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
~OLI can pull the shift lever out of PARK (P).
2-32

Shifting Out of PARK (P)
(Automatic Transmission)
Your vehicle has a brake-transmission shift interlock.
YOLI have to fully apply your regular brake before you
can shift
from PARK (PI 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 3.
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 it manual transfer case
shift lever, be sure your transfer case is in a drive gear.
Your vehicle could roll
if it isn't.
If you are parking on a hill. or if your vehicle is pulling
a trailer, see "Towing a Trailer" in the Index.
