RESTRAINTS
Your
GMC
Motorhome
is
equipped
with
lap
belts
in
the
driver
and
front
passenger
seating
position(s), as
well
as
certain
other
seating
loca-
tions
in
the
Motorhome
.
To
help
lessen
the
chance
of
injury
and/or
the
severity
of
injury
in
accidents
or
sudden
stops,
General
Motors
rec-
ommends
that
people
riding
in
the
vehicle
be
properly
restrained,
with
the
belt restraints
pro-
vided,
including
pregnant
women
and
children
of
all
ages
.
See
following
pages
for
information
on
restraint
of
pregnant
women, and
of
children
.
CAUTION
To help
lessen
the
chance
of
injury
and/or
the
severity
of
injury
in
the
event
of
an
accident
:
Always
put
on
lap
belts
with both
arm
rests
in
the
DOWN
position,
taking
care
that
lap
belt
is
not
wedged
between
arm
rest
and
seat
.
Once
lap
belt
is
buckled
snugly,
the
arm
rest
may
be
positioned
for
use
.
DO
NOT
route
lap
belt
in
front
of,
through,
or
on
top
of
the
arm
rest
as-
sembly
when
it
is
in
use
.
See
illustra-
tions for
proper
routing
of
lap
belts

between
seat
cushion
and
arm
rests
.
A
snug
-fit
and
a low
lop
belt position
are
essential to
lessen
the chance
of
in-
jury
and/or
the
severity
of
injury
in
the
event
of
an
accident,
because
this
spreads
the
force
by
the lap
belt
in
a
collision
over
the strong hip
bone
struc-
ture
rather
than
across
the
soft
abdom-
inal
area
.
Never
use
the
same
belt
for
more
than
one
person
at
a
time
;
avoid
wearing
belts
in
a
twisted
condition
;
do
not
allow
belts
or
hardware
to
become
damaged
by
being
pinched
between
the
seat
structural (metallic)
members
or
in
the
door
.
The
driver
and
front
passenger
seating
posi-
tions
-
have
belt retractors
which
are
designed
to
automatically take
up
excess
webbing
.
Adjust
seat to
your
satisfaction
and
sit
erect
and
well
back
in
the
seat
.
In a
single
motion,
pull
webbing
across
lap
far
enough
to
permit
inserting
metal
latch
plate
end
of
lap
belt into
the
buckle,
until
a
snap
is
heard
.
If
webbing
is
not
pulled
out
far
Lap
Belt
(Front
Seating
Positions)
enough
to
reach the
buckle,
let
the
belt
re-
wind
into
the
retractor
to
release
lock
mech-
anism,
so belt
can
be
pulled out
to
the
proper
length
.
Position
lap
belt
across
lap
as
LOW
ON
HIPS
as
possible
.
To
reduce
the
risk
of
slid-
ing
under
the
belt
during
an
accident,
adjust
to
a
SNUG
FIT
by
pulling
belt
firmly
across
lap
in
direction of retractor so
it
can
take
up
slack
.
To
unfasten
seat
belts,
depress
push
button
in
center
of
buckle
.
When
no
longer
in use,
driver
and
front
pas-
senger lap
belts
can
be stowed by
allowing
them
to
rewind
into
their
retractors
.
NOTE
:
Take
care
not
to
let
the
lap
belt
twist
while
it is
being
rewound
into
the
retractor
pro-
vided
for driver
and
front
passenger
seat
.
The
bulk
of
the
twisted
belt
may
cause
the
retractor
to
jam
so
it
will
not
rewind
further,
while
at
the
same
time
the
retractor's
locking
mechanism
may
prevent
the
belt
from
being
withdrawn
.
If
a
belt
should
become
jammed,
you
may
be
able
to
release
it
by
working
the
belt
in
and
out
until
the
belt
rewinds
far
enough
to
unlock
.
If
lap
belt
remains
jammed
or
other
parts
of
the

RESTRAINT
OF
PREGNANT
WOMEN
To
help
lessen
the
chance
of
injury
and/or
the
severity
of
injury
to
a
pregnant
woman
and
her
unborn
child
in
the
event
of
an
accident,
General
Motors
recommends
that
pregnant
women
use
the
lap
belt,
worn
as
low
and
snug over
the
hips
as
possible,
as
advised
for
regular
seat belt
use
.
LAP
BELT
INSPECTION
Periodically
inspect
belts,
buckles,
latch
plates,
retractors,
and
anchors
for
proper
operation,
and
also
for
damage
that
could
lessen
the
effectiveness
of
the
restraint
sys-
tem
.
Keep
sharp
edges
and
damaging
objects
away
from
belts
and
other
parts
of
restraint
system
.
Replace
belts
if
cut,
weakened,
frayed,
or
subjected to
collision
loads
.
Check
that the
anchor
mounting
bolts
are
tight
.
Have
questionable
parts
replaced
.
Keep
belts
clean
and
dry
.
Clean
only with mild soap
solution
and
luke-
warm
water
.
Do
not bleach
or
dye
belts since
this
may
severely
weaken
them
.
CHILD
RESTRAINT
Children
in
vehicles
should
be
restrained
to
lessen
the
risk
of
injury
in
accidents,
or
sudden
stops
.
In using
any
infant
or
child
restraint
sys-
tem, read
and
comply
with
all
installation
and
usage
instructions
.
All
unused
lap
belts
near
the
child
should
be
stowed
properly
to
help prevent
them
from
striking
the
child
in
the
event
of
an
accident
.
Lap
belts
without
storage
provisions
should
have
buckles
latched
and
belts
adjusted
to
remove
slack
.
If
a
child
is
traveling
in
a
vehicle
not
equipped
with
an
appropriate
infant
or
child
restraint
sys-
tem,
the
following
precautions
should
be
taken
:
1
.
Infants
unable
to
sit
up
by
themselves
should
be
restrained
by
placing
them
in
a cov-
ered,
padded
bassinet
placed
crossways
in
the
vehicle
(widthwise)
on
the
seat
.
The
bassinet
should
be
securely
restrained
with
the
regular
vehicle
belts
.
2
.
Children
able
to
sit
up by
themselves
should
be
placed
on
a
seat
and
lap
belted
.
Never
allow
a
child
to
stand
or kneel
on any
seat
or
elsewhere
in
the
vehicle,
once
it is
underway
.
TRAILER
HAULING
Towing
a
trailer
will
affect
handling,
durabil-
ity
and
economy
.
Maximum
safety
and
satisfac-
tion
depends
upon
proper
use
of
correct
equip-
mentand
avoiding
overloads
and
other
abusive
operation
.
The
maximum
loaded
trailer
weight
which
you
can
pull
withyour
vehicle
depends
on
what
special
equipment
has
been
installed
.

.
This
could
overload
your
vehicle
andseriously
affect
vehicle
per-
formance
and-
.vehicle
handling
which
in turn
could
result
in
personal
injury
.
To
assist
in
attaining
good
handling
of
the
Vehicle
Trailer
Combination,
it is
important
that the
trailer
tongue
load
be
maintained
at
approximately
10
%
of the
loaded
trailer
weight
.
Tongue
loads
can
be
adjusted
by
proper
distri-
bution
of
the load
in
the
trailer,
and
can
be
checked
by
weighing
separately
the
loaded
trailer
and
then
the
tongue
.
The
GVW
of
this
vehicle
is
reduced
by an
amount
equal
to
the
trailer
tongue
load
on
the
trailer
hitch
.
Actual weight
reduction
to
com-
pensate
for
trailer
tongue
load
is
made
by
re-
ducing

OPERATION
IN
FOREIGN
COUNTRIES
Your
vehicle's
engine
is
designed
to
operate
on
unleaded
or
leaded
fuel
of
approximately
91
research
octane
number
.
If
you
plan
to
operate
your
vehicle outside
the
continental
limits of
the
United
States
or
Canada,
there
is
a
possibility
that
the
best
fuels
available
are so
low
in
anti-knock
quality
that
excessive
knocking
and
serious
engine
damage
may
result
from
their
use
.

TRIP
TIPS
A
small
amount
of
preparation
prior
to a
trip
will
save
a
lot
of
time
when
traveling
.
When
loading
heavy
items
into
your
Motor-
home
try
to
store
them
as
low
and
centrally
as
possible
.
This
will
aid
performance
and
handling
of
the
vehicle
.
Remember
even thoughan
item
may
not
weigh
much
individually
the

of
several
of

(Refer
to
the
"IMPORTANTINFORMATION
ON

section
of
this
manual
for
further
information
.)
Before
leaving
any
camp-site
make
sure
all
litter
has
been
picked
up
.
When
traveling
in
winter
it is
recommended
that
the
water
tank
not be
filled
until
the
des-
tination
is
reached
.
This
will
ensure
that
the
vehicle
has
thoroughly
warmed
up
.
The
water
and
holding
tank
systems
should
be
drained
be-
fore
leaving
for
home
.
Also,
at
this
time,
put
some
non-toxic,
non-flammable
anti-freeze
into
the
sink
and
shower
traps
.
Heat
tape
has
been
found
useful
in
preventing
pipe
freeze-up,
where
power
is
available
.
Some
non-toxic,
non-
flammable
anti-freeze
in
the holding
tank
will
help
keep
the
tank
contents
from
freezing
.
The
recirculating
toilet
should
be
drained
immedi-
ately
at
the
end
of
the
trip
.
DRIVING
TIPS
The Motorhome
driver
controls
are
auto-
motive-type
to
make
the
vehicle
as
comfortable
as
possible
.
The
steering
and
braking
controls
are
power
assisted to
help
make
driving
as
effortless
as
possible
.
However,
it
must
be
remembered
that
the
Motorhome
is
much
higher,
wider,
and
heavier
than
a
family
automobile
.
Since the
Motorhome
is
9-ft
.
2-in
.
high,
with
the
roof
mounted
air
conditioner,
additional
care
is
required
to
watch
for
low
bridges
and
over-
passes
.
TREE
BRANCHES
CAN
DO
CON-
SIDERABLE
DAMAGE
TO
THE
WIND-
SHIELD
ORROOF
OF
THE
VEHICLE
TOO,
SO
WATCH
FOR
THEM
.
The
Motorhome
power-to-weight
ratio
is
lower
than
that
of
the
average
automobile
.
Therefore
it is
