86 Instruments and Controls
Parking Brake Light
This indicator light comes on when
the parking brake lever is pulled
with the engine control switch on.
This light also stays on when the
parking brake is not fully released
and the engine control switch is on.
If this warning light stays on, see
your dealer.
The illumination of the parking brake
light does not necessarily ensure
firm application of the parking brake.
The parking brake lever must be
sufficiently pulled up and locked.
Be careful not to drive the vehicle
with the parking brake lever still
pulled up.
Brake Low Vacuum Warning
Light
This light should come on briefly
when the engine control switch is
turned to the ON position, and then
should go out after the engine is
started. If the light does not come
on when the engine control switch is
turned to ON, it could indicate a
burned out bulb or a blown fuse.
Have the system repaired if the light
does not come on during this check.
The warning light and buzzer will
come on simultaneously when the
brake booster’s vacuum or pressure
becomes insufficient either during
driving or when the engine control
switch is in the ON position, or when
there is an abnormality in the
charging system, such as an
alternator malfunction or loosening
or splitting of the fan belt or
whenever the hydraulic brake booster (HBB) becomes faulty. The
warning buzzer will stop sounding
when the parking brake is engaged.
On 4500, 4500HD, and 4500XD, the
brake low vacuum warning light and
warning buzzer should come on to
indicate low vacuum reserve for
brake power assist. At the same
time, the Back up Electric Vacuum
Pump operates.
(5500HD, 5500XD models) When
the HBB pressure is low, and/or the
HBB fluid (Dextron©
–III) level is
low, the light and warning buzzer
should come on. Do not use brake
fluid in the brake booster reservoir.
Use only Dextron© –III ATF.
4500 models are equipped with a
Back up Electric Vacuum Pump that
will turn on if brake booster vacuum
becomes insufficient.
If this happens while driving:
. Do not pump the brakes. The
system is designed to stop the
truck with reserve power assist if
the pedal is held down. This

Vehicle Care 327
Danger (Continued)
at least 5 minutes. Following this,
you should seek medical
assistance.
When using tools or other metal
objects in the vicinity of the
battery, take care to prevent them
from coming into contact with the
positive terminal. As the vehicle
itself will conduct electricity, any
such contact can result in a
short-circuit and a highly
dangerous electric shock.
A vehicle battery generates
extremely flammable hydrogen
gas. For this reason, operations
producing sparks or requiring the
usage of an open flame must
never be carried out near a
vehicle battery. Failure to observe
this precaution can result in
explosion if the hydrogen gas
ignites. Whenever wiping up
battery fluid, a damp cloth should
be used.(Continued)
Danger (Continued)
Batteries produce explosive
gases, contain corrosive acid,
and supply levels of electrical
current high enough to cause
burns. Therefore, to reduce the
risk of personal injury when
working near a battery:
. Always shield your eyes
and avoid leaning over a
battery whenever possible.
. Do not expose a battery to
open flames or sparks.
. Do not allow battery acid to
contact eyes or skin. Flush
any contacted area with
water immediately and
thoroughly, and get
medical help.
. Follow each step in the
jump starting instructions.
Always stop the engine whenever
the battery is to be inspected. (Continued)
Danger (Continued)
Dilute sulfuric acid is used as the
battery fluid. Special care must be
taken to ensure that this fluid
does not come into contact with
skin, clothing, or metal surfaces.
When disconnecting the cables
from the terminals, start with the
negative terminal. When
connecting them, the negative
terminal should be
reconnected last.
You and others could be seriously
injured.
{Warning
For safety and the protection of
the vehicle, do not push-start the
vehicle.

Vehicle Care 333
After Towing
After towing the vehicle, block the
rear wheels and install axle shafts
or driveshaft.
Apply the parking brake before
disconnecting from the towing
vehicle.
Front End Towing (All Wheels On
the Ground)
Your vehicle may be towed on all
wheels provided the steering is
operable. Remember that power
steering and brakes will not have
power assist. There must be a tow
bar installed between the tow
vehicle and the disabled vehicle.
Towing with all wheels on theground
1. Bumper
2. Tow Hook
3. Front Axle
4. Towing Guide
5. Towing Chain
To prepare a disabled vehicle for
front end towing with all wheels on
the ground, the following steps are
necessary:
.Block the rear wheels of the
disabled vehicle.
. For gasoline vehicles, move the
selector lever into "N" position,
vehicles can be towed at speeds below 48 km/h (30 mph) and up
to distances less than
80 km (50 mi).
. Disconnect the driveshaft at the
rear axle. Secure the driveshaft
to the frame or crossmember.
When towing, disconnect the
driveshaft at the rear axle to ensure
the transmission is not damaged.
The rear end of the driveshaft must
be disconnected and safely secured
if the 80 km (50 mi) or 48 km/h
(30 mph) is exceeded.
Provide wood blocking to prevent
towing chains and bar from coming
into contact with the bumper.
If there is damage or suspected
damage to the rear axle, remove the
axle shafts.
Cover the hub openings to prevent
the loss of lubricant or entry of dirt
or foreign objects.
After Towing
After towing the vehicle, block the
rear wheels and install axle shafts
or driveshaft.
