4-12 Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. You can
avoid these problems by braking
-- if you can stop
in time. But sometimes you can't; there isn't room.
That's the time for evasive action
-- steering around
the problem.
In emergencies like these, first apply your brakes. See
ªBraking in Emergenciesº earlier in this section. It is
better to remove as much speed as you can from a
possible collision. Then steer around the problem, to the
left or right depending on the space available. Since
your vehicle has anti
-lock brakes, you don't need to
release the brakes to maintain steering control.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o'clock positions, you may be
able to turn it just enough to miss the object without
removing either hand. But you must act fast, steering
precisely. The more sharply you turn, the greater the
chance of a skid, a rollover or a ªjackknifeº with a
tractor
-trailer. Just as quickly straighten the wheel once
you have avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving at
all times and wear safety belts properly.

Tie a red cloth to your mirror arm to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle if any is blocking
your exhaust pipe. And check around again from
time to time to be sure snow doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery (or batteries) charged. You will need a
well
-charged battery (or batteries) to restart the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater run for a while.

Here are specific towing instructions:
Towing Your Vehicle From the Front
(Front Wheels Off the Ground)
Before Towing
Block the rear wheels of the disabled vehicle. On
vehicles with air brakes, release the emergency brake
system by compressing the brake chamber springs
as outlined in this section. (This is to prevent the
possibility of the emergency brake being applied
during towing.)
On vehicles with hydraulic brakes, release the parking
brake fully by moving the lever to the fully
-released
position.
Disconnect the propshaft at the rear axle (forward axle
on tandem axle models). Secure the propshaft to the
frame or crossmember.
Towing the Vehicle with the Front Bumper Removed
1. Remove the front bumper.
2. Connect and lock the lift chains to the front axle,
outside of the spring anchor plates as shown.
A. Spring Anchor Plate
B. Lift Chain
C. Front Axle
3. Place a 6º x 6º x 5' hardwood beam underneath and
slightly behind the front spring shackle brackets.
4. Connect the lift chains to the tow bar and raise the
tow bar until lift chain slack has been taken up and
the hardwood beam is fully seated against the spring
shackle brackets as shown.

5-12
A. Shackle Bracket
B. Tow Bar
C. Lift Chain
D. Hardwood Beam
5. Raise the vehicle to the required height.Towing the Vehicle with the Front Bumper Installed
1. Connect and lock the lift chains to the front axle,
outside of the spring anchor plates as previously
shown.
2. Place a 6º x 6º x 5' hardwood beam underneath and
slightly behind the front spring shackle brackets as
previously shown.
3. Connect the lift chains to the tow bar and take up the
slack in the chains until the tow bar is within 4º of
the front bumper facing. Place a 2º x 12º x 40º
hardwood board with rubber pads against the front
bumper and secure as shown.

5-14
Single Drive Rear Axle
Disconnect the propshaft at the rear axle. Secure the
propshaft to the frame or crossmember.
Tandem Drive Rear Axles
(Forward Axle Off the Ground)
Raise the front of the vehicle until the forward tandem
axle wheels are off the ground. Remove the rearward
propshaft.Tandem Drive Rear Axle (Both Axles on the Ground
Due to Type of Suspension or Attached Load)
Disconnect the propshaft at the forward tandem axle.
Secure the propshaft to the frame or crossmember.
If there is damage or suspected damage to the axle(s),
remove all axle shafts. Cover the hub openings to
prevent the loss of lubricant or entry of dirt or
foreign objects.
After Towing
1. Block the rear wheels and install axle and propshafts.
2. Check for proper phasing of universal joints.
3. Apply the emergency brake system before
disconnecting from the towing vehicle.

5-15 Towing Your Vehicle From the Front
(All Wheels On the Ground)
Your vehicle may be towed on all wheels provided the
steering is working. Remember that the power brakes
and power steering will not have power assist. Vehicles
with air brakes will not have brakes. There must be a
tow bar installed between the towing vehicle and the
disabled vehicle.
Before Towing
Block the wheels of the disabled vehicle. On vehicles
with air brakes, release the emergency brake system by
compressing the brake chamber springs as outlined in
this section. (This is to prevent the possibility of the
emergency brake being applied during towing.)
On vehicles with hydraulic brakes, release the parking
brake fully by moving the lever to the fully
-released
position.
Disconnect the propshaft at the rear axle (forward axle
on tandem axle models). Secure the propshaft to the
frame or crossmember.
If there is damage or suspected damage to the axle(s),
remove the axle shafts. Cover the hub openings to
prevent the loss of lubricant or entry of dirt or
foreign objects.After Towing
1. Block the rear wheels and install axle and propshafts.
2. Check for proper phasing of universal joints.
3. Apply the parking brake system before
disconnecting from the towing vehicle.
4. Check and fill with oil as required.
Towing Your Vehicle From the Rear
Before Towing
Secure the steering wheel to maintain a straight
-ahead
position. Make certain that the front axle is not loaded
above the front axle Gross Axle Weight Rating (GAWR)
as indicated on the vehicle's Gross Vehicle Weight
Rating (GVWR) label. See ªGross Vehicle Weight
Rating (GVWR)º in the index for more information.
After Towing
Block the rear wheels and release the steering. Apply the
parking brake system before disconnecting from the
towing vehicle.
Refer to the transmission shift label for additional
information.

5-16 Releasing Air-Operated Parking Brakes
(If Equipped)
If your vehicle has air brakes, you could have a special
towing problem. If your vehicle has to be towed because
of a complete loss of air pressure from both systems, the
parking brakes will have automatically engaged. The
tow operator can release the brakes manually by using
the following steps. Then your vehicle can be towed
with all wheels or only the rear wheels on the ground.
1. Block the wheels of the vehicle.
2. Remove the release stud and nut from the side of the
brake chamber. Some chambers have studs which are
visible at all times.
3. Remove the rubber
cap from the rear of
the chamber.
4. Put the release stud, nut and flat washer into
the chamber.
5. Turn the stud clockwise a quarter of a turn.

5-17
6. Turn the stud nut
clockwise several turns
to release the brakes.
Follow the same
procedure to release the
other brake.
7. At the repair facility, apply air pressure of at least
70 psi (480 kPa) to the brake chambers, either from
an external air supply or the vehicle's air system.
8. Turn the stud nut counterclockwise several turns.
Remove the stud from the chamber.
9. Replace the stud and washer and tighten the nut
into the side of the chamber.
10. Replace the rubber cap.Engine Overheating
You will find a coolant temperature warning gage on
your vehicle's instrument panel, as well as a low coolant
warning light. Your vehicle also has a check gages
warning light on the instrument panel.
