a
specially
formulatedsyn-
thetic
gear
oil
that
is
available

department
.

Brake
Fluid

Brake
fluid
absorbs
moisture
easily,
and
moisture
in
the
fluid
affects
brake
performance
and
reliability
.
This
is
why
brake
fluid
should
be
flushed
from
the
system
every
two
years
.
When
re-
placing
or
adding
brake
fluid,
use
only
new
(luid
from
previously
unopened
containers
.
Do
not
use
brake
fluid
that
has
been
bled
from
the
system,
even
ifit
is
brand
new
.
Use
only
DOT
4
brake
fluid
.
See340

information

recommends

.

either
by

Do

in

also
can
act

Wash

Rinse
using
plenty
of

water

Wipe
the

dry
witha

to
prevent

Waxing

For
a
long-lasting,protective,
and
glossy
finish,
apply
a
hard
wax
after
thecar
has
been
washed
and
dried
.
Use
carnauba
or
synthetic
based
products
.
Waxing
is
not
needed
after
every
washing
.
You
can
tell
when
waxing
is
required
by
looking
at
the
finísh
when
it
is
wet
.
If
the
water
coats
the
paint
in
smooth
sheets
instead
of
forming
beads
that
rol¡
off,
a
new
coat
of
wax
is
needed
.
Wax
shouldnot
be
applied
to
black
trim
pieces,
rub-
ber,or
other
plastic
parts
.

Polishing

Use
paintpolish
only
if
the
finish
assumes
a
dull
lock
after
long
service
.
Polish
can
beused
to
remove
tar
spots
and
tar-
nish,
but
afterwards
a
coat
of
wax
should
be
applied
to

Leather
Upholstery
and
Trim

Leather
upholstery
and
trim
should
be
periodically
cleaned
using
a
slightly
damp
cotton
or
wool
cloth
.
The
idea
is
to
get
rid
of
the
dirtin
the
creases
and
pores
that
can
cause
brittleness
and
premature
aging
.
On
heavily
soiled
areas,
usea
mild
deter-
gent
(such
as
Woolite®)
or
other
specially
formulated
leather
r

cleaners
.
Use
two
tablespoons
to
one
quart
of
cold
water
.
Dry

the
trim
and
upholstery
completely
using
a
soft
cloth
.
Regular
use
