tow GMC JIMMY 1997 Owner's Manual

When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near-frontal crash. The air bag will inflate
only
if the impact speed is above the system's designed
"threshold level."
If your vehicle goes straight into a
wall that doesn't move or deform. the threshold level is
about
14 to 18 mph (23 to 29 km/h). The threshold level
can vary, however,
with specific vehicle design. so that
it can be somewhat above or below this range. If your
vehicle strikes something
that will move or deform, such
as a parked car. the threshold level will be higher. The
air
bag is not designed to inflate in rollovers, side
impacts or rear impacts. because inflation would not
help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
Inflation is determined
by the angle of the impact and
how quickly the vehicle slows down in frontal and
near-frontal impacts.
The air bag system
is designed to work properly under a
wide range of conditions, including off-road usage.
Observe safe driving speeds. especially
on rough terrain.
As always. wear your safety belt. See "Off-Road
Driving"
in the Index for Inore tips on off-road driving.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is
in a crash. The sensing
system triggers a release of gas from
the inflator. which
inflates
the air bag. The inflator, air bag and related
hardware
are all part of the air bag module inside the
steering wheel.
How does an air bag restrain?
In tnoderate to severe frontal or near-frontal collisions.
even belted occupants can contact the steering wheel.
The air bag supplements the protection provided by
safety belts. Air bags distribute the force
of the impact
more evenly over
the occupant's upper body. stopping
the occupant more gradually.
But air bags would not
help you in many types of collisions, including
rollovers. rear impacts and side impacts. primarily
because an occupant's motion is
not toward the air bag.
Air bags should never be regarded as anything more
than a supplement
to safety belts. and then only in
moderate to severe frontal or near-frontal collisions.
1-23

Never do this. Here two children are wearing the same belt. The
belt can’t properly spread the impact forces. In a
crash, the two children can be crushed together
and seriously injured.
A belt must be used by
only one person at a time.
What if
a child is wearing a lap-shoulder belt,
but the child is
so small that the shoulder belt is
very close to the child’s face or neck?
A: Move the child toward the center of the vehicle, but
be sure that the shoulder belt still is on the child’s
shoulder,
so that in a crash the child’s upper body
would have the restraint that belts provide.
If the
child is sitting in a
rear outside position of a
four-door model, see “Rear Safety Belt
Comfort
Guides’’ in the Index. If the child is so small that
the shoulder belt is still very close to the child’s
face or neck, you might want to place the child in
a
seat that has a lap belt, if your vehicle has one.

New Vehicle “Break-In”
NOTICE:
Your modern vehicle doesn’t need an elaborate
“break-in.” But it
will perform better in the long
run
if you follow these guidelines:
0 Keep your speed at 55 mph (88 km/h) or
less for the first
500 miles (805 km).
0 Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
200 miles (322 km) or so. During this time
your new brake linings aren’t yet broken in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every
time you get new brake linings.
See “Towing
a Trailer” in the Index for
more information.
0 Avoid making hard stops for the first
Don’t tow a trailer during break-in.
Ignition Positions
Use the key to turn the ignition switch to five different
positions.
C
I
ACCESSORY (A): ACCESSORY lets you use things
like the radio and the windshield wipers when the
engine
is off. Push in the key and turn it toward you.
Your steering wheel will remain locked. just as it was
before you inserted the key.
2-13

NOTICE:
Don’t operate accessories in the ACCESSORY
position for long periods of time. Prolonged
operation of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
LOCK
(B): This position locks your ignition, steering
wheel and transmission. It’s
a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned
to LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. Use OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This starts your engine.
On manual transmission vehicles, turning the key
to
LOCK will lock the steering column and result
in a loss
of ability to steer the vehicle. This could
cause a collision.
If you need to turn the engine
off while the vehicle is moving, turn the key only
to
OFF. Don’t press the key release button while
the vehicle is moving.
I NOTICE: I
If your key seems stuck in LOCK and you can’t
turn it, be sure you are using the correct key;
if
so, is it all the way in? If it is, then turn the
steering wheel left and right
while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it
could break the key or the
ignition switch.
If none of this works, then your
vehicle needs service.

Manual Transmission
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor.
2. If it doesn’t start right away, hold your key in
START. If it doesn’t start in 10 seconds. push the
accelerator pedal all the way clown I‘or five 11101-e
seconds, or until it starts.
I NOTICE:
Your engine is designed to work with the
electronics
in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part
of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
2-16

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.

AUTOMATIC OVERDRIVE (a): This position is for
normal driving.
If you need more power for passing,
and you’re:
Going less than about 35 mph (56 km/h), push your
accelerator pedal about halfway down.
0 Going about 35 mph (56 kdh) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
AUTOMATIC OVERDRIVE
(@) should not be used
when towing
a trailer, carrying a heavy load. driving on
steep hills, or for off-road driving. Select DRIVE
(D)
when operating the vehicle under any of these conditions.
DRIVE (D): This position is also used for normal
driving, however
it offers Inore power and lower fuel
economy than AUTOMATIC OVERDRIVE
(@). You
should use DRIVE (D) when towing a trailer, carrying a
heavy load, driving on steep hills or winding roads or
for off-road driving.
SECOND (2): This position gives you more power but
lower
fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on. You
can
also LIS~ SECOND (2) for starting your vehicle
from
a stop on slippery road surfaces.
FIRST (1): This position gives you even more power
(but lower fuel economy) than
SECOND (2). You can
use
it on very steep hills, or in deep snow or mud. If the
selector lever
is put in FIRST (1) while the vehicle is
moving forward. the transmission won’t shift into
FIRST
( I) until thc vehicle is going slowly enough.
NOTICE:
If your rear wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use your brakes or shift into
PARK (P) to hold your vehicle in position
on a
hill.

The front axle portion of the diagram on the indicator
will light up when you shift
into four-wheel drive. A
slight delay between shifting and the pattern's lighting is
normal. If the pattern does not light up, or if the front
axle lights
do not go out after you shift out of
four-wheel drive, have your dealer check your system.
Turn
the INT LIGHTS switch located to the right of
your headlamp switch to dim your transfer case
indicator light when your headlamps or parking lamps
are on. This
will also cause your instrument p.anel lights
to dim.
2HI: This setting is for driving in most street and
highway situat.ions. Your front axle
is not engaged in
two-wheel drive.
4HI: This setting engages your front axle to help
drive
your vehicle. Use 4H1 when you need extra
traction. such
as on snowy or icy roads. or in most
off-road situations.
N SET PARK BRAKE: Shift to this neutral setting
only when your vehicle needs to be towed.
4LO: This setting also engages your front axle to give
you extra traction and provides extra gear reduction.
YOLI may never need 4LO. It sends the maximum power
to all four wheels. You might choose 4L0 if you were
driving off-road
in sand, mud or deep snow and
climbing or descending steep hills.
You can shift from
2HI to 4H1 or from 4HI to 2HI while
the vehicle
is moving. Do not press the transfer case
shift lever button when shifting from
2HI to ;CHI or
from
4HI to 2HI.
To shift your transfer case into N SET PARK BRAKE:
1. Stop the vehicle and shift your transmission into
NEUTRAL
(N).
2. Set the parking brake. Your vehicle can roll unless
the brakes are applied.
3. Pull the transfer case shift lever into N SET
PARK BRAKE.

Parking Brake
To set the parking brake. hold the regular brake pedal
down with your right foot. Push down the parking brake
pedal with your left
foot. If the ignition is on, the brake
system warning light
will come on.
To
release the parking brake hold the regular brake
pedal
down.
NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You
may have to
replace them, and you could also damage other
parts
of your vehicle.
If you are towing a trailer and you must park on a hill,
see "Towing a Trailer" in the Index. That section shows
what to
do first to keep the trailer from moving.
