Your

conditions
of
you

.
When
loading
the
MotorHome,
it is
impor-
tant
that
it
is
properly
loaded
.
All
items
should
be
loaded
as
centrally
and
as
low
as
possible
.
This
is
essential
to
maintain
proper
vehicle
handling
.
Even
though
a
single
item
may
not
weigh
much
alone,
several
of
these
items
may
have
considerable
weight
.
Proper

It
is
recommended
that while the

and
keep
lap

buckled
snugly
at
all
times
.
The

If
webbing
is
not

out
far
enough
to
reach
the
buckle,
let
the
belt
re-
wind
into
the
retractor
to
release

anism,
so
belt
can be
pulled
out
to
the proper
length
.
Position

as
possible
.
To
reduce
the
risk
of sliding

belt
during
an
accident,
adjust

a
SNUG
FIT
by
pulling
belt
firmly
across
lap
in

NOTE
:
Take
care
not
to
let
the
lap
belt
twist
while
it
is
being
rewound
into
the
retractor
.
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withdrawn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
system
do
not
operate
properly take
the
vehicle
to
your
dealer
for
service
.
Lap
belts at

CHILD
RESTRAINT
Children

to
lessen
the
risk of
injury
in

sudden
stops
.
In
using
any
infant
or
child
restraint
sys-
tem,
read
and
follow
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

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

TRAILER
HAULING
Towing
a
trailer
will
affect
handling,
durabil-
ity
and
economy
.
Maximum
safety
and
satisfac-
tion
depends
upon
proper
use
of
correct
equip-
ment
and
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
.
GMC
does
not
recommend
towing
any
trailer
OVER
1,000
POUNDS
GROSS
TRAILER
WEIGHT
unless the
vehicle
HAS
THE
REQUIRED
EQUIPMENT
.
Information
on
trailer
hauling
capabilities,
special
equipment
required,
and
optional
equipment
offered
can
be
obtained
by

.
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
.
When
towing
trailers,
tires
should
be
inflated
to
the
highest
inflation
pressures
shown
on
tire
placard
located
on
glove
box
door
.
The
allow-
able
passenger
and
cargo
load
(GVW)
of
this
vehicle
is
reduced
by an
amount
equal
to the
trailer
tongue
load
on
the
trailer
hitch
.
MAINTENANCE
More
frequent
vehicle
maintenance
is
required
when
being
used
to pull
a
trailer
.

OPERATION
IN
FOREIGN
COUNTRIES
Your
vehicle's
engine
is
designed
to
operate
on
unleaded
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
.
To
obtain
informa-
tion
on
the
quality
of
fuels
available
in
the
countries
in
which
you

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
sum
weight
of
several
of
these
articles
may
be
sub-
stantial
.
When
transporting
luggage
or
other
cargo
in
your
MotorHome,
it is
recom-
mended
that
all
articles
be
secured
in
place
.
This
precaution
will
help prevent
such
items
from
becoming
projectiles
in
the
event
of
an
accident
.

.)
Before
leaving
any
camp-site
make
sure
all

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

.
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

wherepower
is
available
.
Some
non-toxic,
non-
flammable
anti-freeze
in
the
holding
tank
will
help
keep
the

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
.
TREEBRANCHES
CAN
DO
CON-
SIDERABLE
DAMAGE
TO
THE
WIND-
SHIELD
ORROOF
OF
THE
VEHICLE
TOO,
SO
WATCH
FOR
THEM
.

:
[131
The MotorHome
power-to-weight
ratio
is
lower
than
that
of
the
average
automobile
.
Therefore
it is
essential to
compensate
for
less
acceleration
when
moving
into
traffic,
or
when
passing
another
vehicle
.
NEW
VEHICLE
OPERATING
SPEEDS
Driving
speeds
for
your
new
vehicle
should
be
limited
to
a
maximum
of
50
MPH
for
the
first
100
miles,
and
65
MPH
for
the
next
400
miles
with
no
heavy
throttle
accelerations
.
If
your
initial
mileage
is
of
the
around-town
vari-
ety,
which
is
considered
"severe
service"
espe-
cially
in
cold
weather,
be
sure
to
include
some
25
to
50
mile
highway
trips
during
the
break-
in period
and
vary
the
vehicle's
speed
.

NOTES

STA
CLE
ENGINE
EXHAUST
GAS
CAUTION
(CARBON
MONOXIDE)
Avoid
inhaling
exhaust
gases
because
they
contain
carbon
monoxide
which by
itself
is
colorless
and
odorless
.
Carbon
monoxide
is
a
dangerous
gas
that
can
cause
unconsciousness
and
is
potentially
lethal
.
If,
at
any
time,
you
suspect
that
exhaust
fumes
are
entering
the Motor-
Home
from
any
source
have
the
cause
determined
and
corrected
as
soon
as
possible
.
If
you
must
drive
before
the
cause
is
corrected,
drive
only
with
ALL
except
two
rear
windows
FULLY open
and
heating
or
cooling
system
adjusted
for
maximum
ventilation
(see
below)
.
The
best
protection
against
carbon
monoxide
entry
into
the
vehicle
body
is
a
properly
maintained
engine
exhaust
system,
body
and
body
ventilation
system
.
It is
recommended
that
the
exhaust
system
and
body
be
inspected
by
a
competent
mechanic
:
Each time
the
vehicle
is
raised
for
lubrication
or
oil
change
.
"
Whenever
a
change
is
noticed
in
the
sound,
alignment,
or
appearance
of
the
exhaust
system
.
Whenever
the
exhaust
system,
underbody
or
rear
of
the
vehicle
is
damaged
.
See
your
Maintenance
Schedule
folder
for
inspection
procedure
.
To
allow
proper
operation
of
the
