1994 GMC SIERRA tow

If you have four-wheel drive and your transfer case is in “N” (Neutral),
your vehicle will be free to roll, even
if your shift lever is in “P” (Park). So,
be sure the transfer case is in a drive gear - not in “N” (Neutral). Follow
the proper steps to be sure your vehicle won’t move. See “Shifting Into
‘P’
(Park)’’ in the Index.
If you’re pulling a trailer, see “Towing a Trailer” in the Index.
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 satisfixtion out
of four-wheel drive, you must be familiar with it’s operation. Read
the part
that follows before using four-wheel drive.
You should use 2H for most
normal driving conditions.
Rear-wheel antilock brakes
do not work when you shift into four-wheel
drive. Your regular brakes
will still work. When you shift back into
two-wheel drive, your rear-wheel antilock brakes will take over again.

When your headlights or parking lights are on, rotate the dial to the right of
your headlight switch up
to brighten, or down to dim, your transfer case
indicator light.
2H (2-Wheel High): This setting is for driving in most street and highway
situations. Your front axle is not engaged
in two-wheel drive.
4H (4-Wheel High): This setting engages your front axle to help drive your
vehicle. Use
4H when you need extra traction, such as on wet or icy roads,
or in most off-road situations.
N (Neutral): Shift to this setting only when your vehicle needs to be towed
or when using a power take-off.
4L (4-Wheel Low): This setting also engages your front axle to give you
extra power, but should be used only for off-road driving.
You can shift from
2H to 4H or from 4H to 2H while the vehicle is moving.
Your front axle will engage faster if you take your foot off of the accelerator
for a few seconds after you shift.
In extremely cold weather it may be
necessary to stop or slow the vehicle to shift
out of 2H.
To shift into or out of 4L or “N” (Neutral):
Slow the vehicle to a roll, about 1-3 mph (2-5 kdh) and shift your
transmission into neutral.
0 Shift the transfer case shift lever in one continuous motion.
Don’t pause
in “N” (Neutral) as you shift the transfer case into 4L, or your
gears could clash.
Remember that driving
in 4H or 4L may reduce fuel economy. Also, driving
in four-wheel drive on dry pavement could cause your tires to wear fdster
and make your transfer case harder to shift.
Front Axle Locking Feature
The front axle locks and unlocks automatically when you shift the transfer
case. Some delay
for the axle to lock or unlock is normal. If the outside
temperature is very hot, or the vehicle has been used under hard driving
conditions, there may be
a slight delay for the axle to unlock.
Whenever you are
in four wheel drive, the rear wheel anti-lock brake
system does not operate. The regular brake system operates normally. When
you shift back into two-wheel drive, the anti-lock brake system will
operate.

A green arrow on the
instrument panel will
flash
in the direction
of the turn or lane
change.
To signal a lane change, just raise or lower the lever until the green arrow
starts to flash.
Hold it there until you complete your lane change. The lever
will return by itself when you release it.
As you signal a turn or a lane change, if the arrows don’t flash but just stay
on, a signal bulb may be burned out and other drivers won’t see your turn
signal.
If a bulb
is burned out, replace it to help avoid an accident. If the green
arrows don’t go on at all when
you signal a turn, check for burned-out bulbs
and a blown fuse
(see “Fuses” in the Index).

Gages can indicate when there may be or is a problem with one of your
vehicle’s functions. Often gages and warning lights work together to let
you
know when there’s a problem with your vehicle.
When one of the warning lights comes on and stays on when you are
driving,
or when one of the gages shows there may be a problem, check the
section that tells you what to do about
it. Please follow the manual’s advice.
Waiting
to do repairs can be costly - and even dangerous. So please get to
know your warning lights and gages. They’re
a big help.
Brake System Warning Light
The red brake system
warning light is
located at the bottom
right corner
of the
instrument cluster
Your vehicle’s hydraulic brake system
is divided into two parts. If one part
isn’t working, the other part can still work and stop you. For good braking,
though, you need both parts working well.
Your vehicle also has rear-wheel anti-lock brakes.
If the warning light
comes on, there could be
a brake problem with either your regular or
rear-wheel anti-lock brakes, or both. Have your brake system inspected
right away.
This light should come on
as you start the vehicle. If it doesn’t come on
then, have it fixed so it will be ready to warn you if there’s a problem.
If the light comes on while you are driving, pull off the road and stop
carefully.
You may notice that the pedal is harder to push. Or, the pedal may
go closer
to the floor. It may take longer to stop. If the light is still on, have
the vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)

Step-Bumper Pad
If your vehicle has a rear step bumper, it may be equipped with a rear step

are stepping on the bumper step.
If you will be using
the bumper to tow a
trailer, you must
remove the center cutout circle to install
the trailer
ball. You
must also remove both outer cutouts to attach
the trailer safety
