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.

5-4 Signal-Stat Turn Signal and Hazard
Warning Flasher (If Equipped)
If you have this system, it lets you warn others. It also
lets police know you have a problem. It makes your
front and rear turn signal lamps flash on and off, but
they won't flash if you're braking.
The switch is on the end of the signal
-stat housing.
To make it work, pull out on the hazard lever until it
locks into place. It works no matter what position your
key is in, and even if the key isn't in.
To turn off the flasher, move
the turn signal lever either
up or down. Then move the
signal lever back to the
center position.
When the hazard warning flashers are on, your turn
signals won't work.
Other Warning Devices
If you carry reflective triangles, you can set one up at
the side of the road behind your vehicle in the
recommended manner per FMCSR (Federal Motor
Carrier Safety Regulation) Section 392.22, to
warn others.

CAUTION:
To help avoid injury to you or others:
Never let passengers ride in a vehicle that is
being towed.
Never tow faster than safe or posted speeds.
Never tow with damaged parts not
fully secured.
Never get under your vehicle after it has
been lifted.
Always use separate safety chains on each
side when towing a vehicle.
If your vehicle uses dragfoilers, be sure to have the
dragfoiler
-to-cab mounting bracket bolts tightened after
your vehicle has been towed.
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. (Note: This is to prevent the
possibility of the emergency brake being applied
during towing.)
On vehicles with hydraulic brakes without an
electric/hydraulic parking brake, release the
parking brake fully by moving the lever to the
fully
-released position.
On vehicles equipped with an electric/hydraulic parking
brake option, remove the propshaft.

After Towing
Block the rear wheels and install axle and propeller
shafts. Check for proper phasing of universal joints.
Apply the emergency brake system before disconnecting
from the towing vehicle. Check and fill the rear axle
with oil as required.
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. (Note: 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.
On vehicles equipped with an electric/hydraulic parking
brake, remove the propshaft.
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
Block the rear wheels and install axle and propshafts.
Check for proper phasing of universal joints. Apply
the parking brake system before disconnecting from
the towing vehicle. Check and fill rear axle with oil
as required.

5-15 Towing Your Vehicle From the Rear
(Rear Wheels Off the Ground)
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 Certification/Tire label.
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.
Releasing Air-Operated Parking Brakes
If your vehicle has air brakes, you could have a special
towing problem. If your vehicle has to be towed because
you had a complete loss of air pressure from both
systems, the parking brakes may have applied. The tow
operator can release the brakes manually by using the
following steps. Then your vehicle can be towed with all
wheels or just the rear wheels on the ground.

CAUTION:
Working on air brakes without first using
the release studs to compress the springs
can lead to injury. Never work on the air
brake chambers without first using the
release studs to compress the brake springs.
When the brake springs are manually
compressed, you will have no brakes.
Release your air
-operated parking brakes
manually only to tow the vehicle. Never
drive the vehicle with the brakes released.
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.
