Power
Steering
Fluid
The
power steering fluid reservoir is located next to the
underhood fuse block on the passenger’s side of the
vehicle. See
Engine Compartment Overview on
page
5-12
for
more information on location.
When
to
Check Power
Steering
Fluid
It
is not necessary to regularly
check
power
steering
fluid
unless you suspect there is a
leak in the
system or
you hear an unusual noise.
A fluid
loss
in this
system
could indicate a problem. Have
the
system
inspected
and
repaired.
How
to
Check
Power
Steering
Fluid
Turn the key
off,
let the engine compartment
cool
down,
wipe
the
cap
and
the top of the reservoir
clean,
then
unscrew the cap
and
wipe
the
dipstick with
a
clean
rag.
Replace the cap
and completely tighten it.
Then
remove
the cap again and
look at the fluid level on the
dipstick.
The level should be at the
FULL
COLD
mark.
If
necessary,
add only enough fluid to bring the
level
up
to
the mark.
What
to
Use
To determine what kind of fluid to use, see
Part
D:
Recommended
Fluids and Lubricants
on
page
6-15.
Always
use the proper fluid. Failure to use
the
proper
fluid can
cause leaks and
damage
hoses
and
seals.
5-36
Windshield
Washer
Fluid
What
to
Use
When
you
need
windshield
washer fluid, be sure to read
the manufacturer’s instructions before use.
If
you will
be
operating
your
vehicle in an area where the
temperature
may fall below freezing, use a fluid that has
sufficient protection against freezing. See
Engine
Compartment
Overview on
page
5-12
for reservoir
location.
Adding
Washer
Fluid
The
CHECK
WASHER
FLUID
message
will
be
displayed
on
the
Driver Information Center
(DIC)
when
the fluid is low.
The windshield washer
fluid reservoir is located in
front of the underhood
fuse
block
on the
passenger’s side of the
vehicle.
Notice:
e
e
e
e
When using
concentrated
washer
fluid,
follow
the
manufacturer’s
instructions
for
adding
water.
Don’t
mix
water
with
ready-to-use
washer
fluid.
Water can
cause
the
solution
to
freeze
and
damage
your
washer
fluid
tank
and
other
parts
of
the
washer
system.
Also,
water
doesn’t
clean
as
well
as
washer
fluid.
Fill
your
washer
fluid
tank
only
three-quarters
full
when
it’s
very
cold.
This
allows
for
expansion
if
freezing
occurs,
which
could
damage
the
tank
if
it
is
completely
full.
Don’t
use
engine
coolant
(antifreeze)
in
your
windshield washer.
It
can
damage
your
washer
system
and
paint.
Open
the
cap
with the washer
symbol
on
it.
Add
washer
fluid until the
tank
is
full.

Notice;
If
you leave your
radio
on, it could be badly
damaged. The repairs wouldn’t be covered by
your
warranty.
3.
Turn
off
the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in
the accessory
power outlets. Turn
off
the radio and all lamps that aren’t
needed. This will
avoid sparks and help save both batteries. And it
could save
your radio!
4.
Open the hoods
and locate the positive
(+)
and
negative
(-)
terminal locations on
the other
vehicle. Your vehicle has
a
remote positive
(+)
jump
starting terminal and a
remote negative
(-)
jump
starting terminal.
The
remote positive

terminal is located in the
engine compartment
on
the passenger’s side of
the vehicle. A
second
remote positive
(+)
terminal
is located on the rear
underseat fuse block. Lift
the red plastic cap to
access the terminal.
The
remote negative
(-)
terminal is located near
the power steering fluid reservoir. It is marked
“GND

page
5-12
for
more information on
location.
You will not
see
the battery
of
your
vehicle
under
the hood. It is located under
the
rear
passenger’s
seat.
You will not
need to access
the
battery
for
jump
starting.
The

Add-on Electrical Equipment
Notice:
Don’t add anything electrical to your vehicle
unless
you
check
with
your
dealer
first.
Some
electrical
equipment
can
damage
your
vehicle
and
the
damage
wouldn’t
be
covered by

Headlamp
Wiring
The
headlamp
wiring
system
has
four individual fuses,
LF
low,
RF
low,
LF
high and
RF
high.
An electrical
overload will cause the lamps to go
on
and
off,
or in
some
cases to remain
off.
If this happens,
have
the
headlamp
wiring
checked right awav.
Windshield
Wiper
Fuses
The windshield wiper
motor
is
protected by an internal
circuit breaker.
If
the wiper motor overheats due to
heavy
snow, the wipers will stop until the motor
cools
and will then restart.
A
fuse powers the wiper motor. If the fuse blows, there
is
an electrical problem. Be sure to have it fixed.
Power
Windows and Other
Power
Options
Circuit breakers protect the power
windows
and
power
seats. When the current load
is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem
is
fixed or goes
away.
5-93
Fuses
and
Circuit
Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the
chance of fires
caused by electrical problems.
Look
at
the silver-colored band inside the fuse. If the
band
is broken
or
melted, replace the
fuse. Be sure you
replace a bad fuse with a new
one
of the identical
size
and
rating. If a fuse should blow,
see your dealer
for service immediately.
If
you
ever have a problem on the road and don’t have
a spare
fuse,
you can “borrow” one that has the
same
amperage. Pick some
feature
of
your vehicle that
you
can
get along without
-
like
the
radio
or cigarette
lighter
-
and
use its fuse, if it
is
the
correct
amperage.
Replace it as
soon as you
can.
The fuses are located in two fuse blocks, one located in
the engine compartment on the passenger’s side and
the other under
the rear seat
on
the driver’s side.
If
a fuse should blow, have
your vehicle serviced by
your dealer immediately.
Underhood
Fuse
Block
The
underhood
fuse
block
is
located
next to the
engine
on
the
passenger’s
side
of
