52 Seats and Restraints
Warning (Continued)
Any unrestrained child could be
injured by striking the vehicle's
interior or by ejection from the
vehicle during an accident or
driving maneuver. Never allow a
child to be held by another
occupant instead of being
properly restrained. If not properly
restrained, the child could strike
the vehicle interior or be crushed
by the person holding the child,
or by other occupants.
Be sure to follow all installation and
use instructions that come with any
child restraint system.
Child restraint systems are designed
to be secured in vehicle seats either
by the lap belt, or the lap portion of
the lap-shoulder belt at that seating
position. The child must also be
secured within the restraint by the
means provided by the child
restraint manufacturer. If the child or the child restraint is not properly
secured, the child risks personal
injury in the event of a collision.
Using a Lap Belt That Has No
Retractor
When securing a child restraint with
the center seat lap belt, pull the
excess webbing through the belt's
adjustment feature, then take these
steps:
.
Once installed, push and pull the
child restraint in all directions to
be sure it is secure. If it comes
loose, flip the end of the belt
with the adjustment feature over
before rebuckling.
. If the child restraint is still not
secure, use the outboard seating
position in the vehicle and
contact your dealer and the child
restraint manufacturer for help.
. Secure the child in the restraint
in accordance with the child
restraint manufacturer's
instructions.
Installation on Outboard Seat
A seat belt locking clip is required
for installation of a child restraint
system on the outboard seat of this
vehicle. A locking clip may usually
be obtained where child restraints
are sold, or by contacting your
dealer for assistance. Make sure the
locking clip is identical to the one
shown on this page. Until you have
the clip, use the child restraint
system only in the center seat.

Seats and Restraints 53
{Warning
To help avoid personal injury or
death during a collision or sudden
maneuver, always thread both the
lap and shoulder belt through the
locking clip when securing a child
restraint on the outboard seat.
If the clip is not used or installed
properly, the child restraint may
move or tip over when your
vehicle turns or stops abruptly.
Secure the child restraint with the
lap belt portion (1) of the seat belt in
accordance with the restraint
manufacturer's instructions. Then
thread both the lap (1) and shoulder
belt (2) portions through the locking
clip. Push and pull the child restraint
in all directions to be sure it is
secure.
Locking Clip Attached to Seat Belt–Side View
1. Lap Belt
2. Shoulder Belt
3. Locking Clip
When your child restraint is not
installed, remove the locking clip to
permit normal use of the
lap-shoulder belt. Keep the locking
clip in the glove box to help prevent
its loss.
Child Restraint with Top Tether
{Warning
We do not recommend using a
child restraint that requires the
use of a top tether. There is no
appropriate place to attach a top
tether anchor behind the seat in
this vehicle.

58 Storage
Information on
Loading the Vehicle
Overloading
{Warning
Overloading can result in loss of
vehicle control and personal
injury or death, either by causing
component failures or by affecting
vehicle handling. It can also
shorten the service life of your
vehicle.
The components of your truck are
designed to provide satisfactory
service if the vehicle is not loaded in
excess of either the gross vehicle
weight rating (GVWR) or the
maximum front and rear gross axle
weight ratings (GAWRs). These
ratings are listed on the vehicle
identification number (VIN) plate,
which is located on the left side rear
pillar panel below the striker (single cab) or on the left center pillar panel
beside the shoulder seat belt anchor
(crew cab).
Gross vehicle weight (GVW) is the
weight of the originally equipped
vehicle and all items added to it
after it has left the factory. This
would include bodies, lift gates,
refrigeration systems, winches,
booms, etc., the driver and all
occupants, and the load the vehicle
is carrying. The GVW must not
exceed the GVWR. Also, gross
weight on each of the front and rear
axles must not exceed the front and
rear GAWRs respectively.
Your dealer can advise you of the
proper loading conditions for your
vehicle. Using selected heavier
suspension components for added
durability may not increase any of
the weight ratings shown on the VIN
and weight rating plate.

Engine Coolant
Temperature Gauge
With the engine control switch in the
ON position, this gauge indicates
the temperature of the engine
coolant.“C”means cold while “H”
means hot. During operation, the
needle should stay in the safety
zone. See Engine Overheating
0 259.
{Warning
If the engine coolant temperature
gauge shows an overheat
condition or you have any other
reason to suspect the engine may
be overheating, continued
operation of the engine, even for
a short time, may result in a fire
and the risk of personal injury and
severe vehicle damage. Take
immediate action as outlined in
Engine Overheating. See Engine
Overheating 0259.
Caution
If the needle goes up above the
upper limit and enters the H zone,
the engine is likely to overheat.
Immediately pull safely off the
road out of the way of traffic and
take the necessary actions to
deal with engine overheating.
If the needle nears the H zone but

following situations:
.
Drop in the level of brake fluid
(due to brake lining wear or fluid
leakage).
. Abnormality in the charging
system (such as an alternator
malfunction or loose or split
fan belt).
. Abnormality in the anti-lock
brake system (ABS) and
Electronic Braking force
Distribution (EBD) functions.

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 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 (Dexron
–VI) level is low,
the light and warning buzzer should
come on. Do not use brake fluid in
the brake booster reservoir. Use
only Dexron –VI ATF.
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
reserve is greatly reduced each
time you apply and release the
brakes.
. Stopping distance may be
longer. .
You may have to push much
harder on the brake pedal.
. Have the vehicle repaired before
you continue driving.
The buzzer stops when the selector
lever is shifted to the P position.
{Warning
Do not drive while the buzzer
sounds as the brakes are not
operating to their full capacity.
You and others could be seriously
injured.
