1997 GMC JIMMY transmission

Shifting from 4LO to 4HI or 2HI
To shift from 4LO to 4HI or 2H1, your vehicle must be
stopped or moving
less than 3 mph (4.8 kndh) with the
transnJission
in NEUTRAL (N) or the clutch pedal
engaged. The preferred method for shifting out of
4LO is to have your vehicle moving
1 to 2 mph (1.6 to
3.2 kdh). Press and release the 4HI switch. You must
wait for the
4HI indicator light to stop flashing and
remain illuminated before shifting your transmission
into gear
or releasing the clutch pedal.
If the 4Hi switch is pressed when your vehicle is in gear
and/or moving. the 4HI indicator light
will flash for
30 seconds but not complete the shift unless the
vehicle is moving slower than
3 nlph (4.8 km/h) 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 4H1, your transmission
indicator switch
may require adjustment. With your
transmission
in NEUTRAL (N), press and release the
4HI switch. While the 4HI indicator light is flashing,
shift your transmission into PARK
(P). Wait until the
4HI indicator light remains illuminated before shifting
your transmission into gear. This
will get you into 4H1,
but you should take your vehicle in for service to restore
norrnal operation.

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:

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).

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.

Running Your Engine While You’re
Parked (Automatic Transmission)
It’s better not to park with the engine running. But if
ever have to, here are some things to know.
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
-- with
CO -- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be
a blizzard.

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 (P).
If you have four-wheel drive with a manual transfer case
shift lever and your transfer case is in NEUTRAL

Cruise Control (If Equipped)
With cruise control, you can
maintain
a speed of about
25 mph (40 krn/h) or more
without keeping your foot
on the accelerator. This
can
really help on long trips.
Cruise control
does not
work at speeds below about
25 rnph (40 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut
off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will
shut off.
A CAUi ION:
I
Cruise control can be dangerous where you
can’t drive safely at
a steady speed. So,
don‘t use your cruise control on winding
roads or in heavy traffic.
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.

Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (kndh).
Your odometer shows how far your vehicle has been
driven,
in either miles (used in the United States) or
kilometers (used
in Canada).
Your odometer is tamper resistant.
It will show silver lines
between the numbers
if someone tries to turn it back.
You may wonder what happens
if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then
it must be. But if
it can't, then it's set at zero, and a label must be put on
the driver's door to show the old mileage reading when
the new odometer was installed.
Trip Odomet
The trip odometer can tell you how fir your vehicle has
been driwn since you last set the
trip odometer to zero.
To set the trip odome.ter to zero, press the button near
the readout.
Tachometer (If Equipped)
The tachometer displays the engine speed in revolutions
ner minute (rprn). Each
tachometer has
a different limit depending on the
powertrain
in your vehicle. The tachometer has three
areas: normal operating range, red warning range and
red danger range.
The normal operating range shows your engine speed
during normal driving conditions.
For example, when
the needle points
to 2, it means the engine is running at
2.000 revolutions per minute (rpm). The tachometer
needle
will vary all the time that the engine is running.
The shaded red warning range tells you that your engine
speed
is reaching its upper limits. Don't drive very long
with the tachometer
in the red warning range. If you
have
a manual transmission. shift to a higher gear as
soon as possible. If you have an automatic transmission,
lift your foot off of the accelerator pedal.
The solid red danger range tells you that your engine speed
is at its upper limits. Your should immediately shift
to a
higher gear, or lift your foot off of the accelerator pedal.
1 NOTICE:
Do not operate the engine with the tachometer in
the red range,
or engine damage will occur.
