- Going about 35 mph (56 km/h) or more, push the accelerator all
the way down.
You’ll shift down to the next gear and have more power.
@ should not be used when towing a trailer, carrying a heavy load,
driving on steep hills, or for
off road driving. Select “D” (third gear)
when operating the vehicle under any of these conditions.
D (Third Gear)
This is like @, but you never go into Overdrive. You should use when
towing a trailer, carrying a heavy load, driving on steep hills, or for
off-road driving.
2 (Second Gear)
This position gives you more power but lower fuel economy. You can
use
“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. If you manually select “2”, the transmission will drive in
second gear.
You may use this feature for reducing torque to the rear
wheels when you are trying to start your vehicle from
a stop on
slippery road surfaces.
1 (First Gear)
This position gives you even more power (but lower fuel economy)
than
“2.” You can use it on very steep hills, or in deep snow or mud. If
the selector lever
is put in “1,” the transmission won’t shift into first
gear until the 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 “P” Park to hold
your vehicle in position on
a hill.

To release the parking brake:
Hold the regular brake
pedal down. Pull the
lever, located just
above the parking
brake pedal, marked
RELEASE to release
the parking brake.
If the ignition is on when the parking brake is released, the brake system
warning light will
go off.
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 are parking on any hill: See “Towing a
Trailer” in the Index. That section shows what to do first to keep the trailer
from moving.
Torque Lock
The parking brake should be set first whenever you leave the driver’s seat.
If you are parked on a hill and the transmission is placed in “P’ (Park)
before the parking brake is set, the weight
of the vehicle may put too much
force on the parking pawl in the transmission. It may be difficult to pull the
selector lever out
of “P” (Park). This is called “torque lock.” To prevent this,
the parking brake should be set
BEFORE moving the gear selector to “P”
(Park).
When preparing to move a vehicle parked on a hill, the selector lever should
be moved out
of “P” (Park) BEFORE releasing the parking brake. Even
when on level surfaces, its a good idea to set the parking brake first before
shifting the transmission from
“P” (Park).
If torque lock does occur, you may have to have another vehicle nudge your
vehicle uphill a
little to take some of the pressure off the transmission while
you pull the selector lever
out of “P’ (Park).

Parking Your Vehicle
(Manual Transmission Models Only)
Before you get out of your vehicle, put your manual transmission in “R”
(Reverse), turn off the engine, and firmly apply the parking brake .
If you have four-wheel drive, 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 pulling a trailer, see “Parking on
Hills” or “Towing a Trailer’’ in the Index.

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 satisfaction 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.

If you need to carry long items, move the cross rails as far apart as they
will go. Tie the load to the cross rails and the side rails or side rail
supports. Also tie
the load to the bumpers. Do not tie the load so tightly
that the cross rails or side rails are damaged.
After moving the cross rails, be sure to tighten all the slider screws.
Trailer Wiring Harness (Option)
An optional 7-wire
harness
is stored under
your vehicle along the
rear frame
crossmember. The
harness has a
30 amp.
in-line fused battery
feed wire and no
connector, and should
be wired by a
qualified electrical
technician.
Securely attach the harness
to the trailer, then tape or strap it to your
vehicle’s frame rail. Be sure
you leave it loose enough so the wiring won‘t
bind or break when turning with the trailer, but
not so loose that it drags on
the ground.
Store the harness in its original position. Wrap the harness together and tie it
neatly so it won’t be damaged.

Step-Bumper Pad
If your vehicle has a rear step bumper, it may be equipped with a rear step
pad at the center
of the bumper. Use this pad to improve footing when you
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
chains.
To remove the pad, lift
the edge
of the pad
from the rear
of the
bumper and swing it
forward. When
the
pad releases from the
pad off.

Towing a Trailer
4-36
ProCarManuals.com

I NOTICE:
Pulling a trailer improperly can damage your vehicle and result\

in costly repairs not covered
by your warranty. To pull a trailer
correctly,
follow the advice in this section, and see your GM
dealer for important information about towing a trailer with
your vehicle.
Every vehicle is ready for some trailer towing. If it was built with trailering
options, as many are, it’s ready for heavier trailers. But trailering is different
than just driving your vehicle
by itself. Trailering means changes in
handling, durability, and fuel economy. Successful, safe trailering takes
correct equipment, and
it has to be used properly.
That’s the reason for this section. In it are many time-tested, important
trailering tips and safety rules. Many of these are important for your safety
and that of your passengers.
So please read this section carefully before you
pull a trailer.
rf You Do Decide To Pull A Trailer
If you do, here are some important points.
There are many different laws having to do with trailering. Make sure
your rig will be legal, not only where you live but also where you’ll
be
driving. A good source for this information can be state or provincial
police.
Consider using a sway control with a utility model if your trailer will
weigh 3,000 pounds (1 36 1 kg) or less, or with a wagon model if your
trailer
will weigh 4,000 pounds (1 800 kg) or less. You should always
use a sway control
with a utility model if your trailer will weigh more
than
3,000 pounds (I 361 kg), or with a wagon model if your trailer
will weigh more than 4,000 pounds (1 800 kg).
You can ask
a hitch dealer about sway controls.
Don’t tow a trailer at all during the first 500 miles (800 km) your new
vehicle is driven. Your engine, axle or other parts could be damaged.
Then, during the first 500 miles (800 km) that you tow a trailer, don’t
drive over
50 mph (80 km/h) and don’t make starts at full throttle. This
helps your engine and other parts of your vehicle wear
in at the heavier
loads.
