5-4 Instruments and Controls
8(Mist):Use for a single wipe.
Hold the band on
z, then release.
For several wipes, hold the band on
zlonger.
6(Adjustable Interval Wipes): Use
to adjust the delay time between
wipes. Turn the band up for more
frequent wipes or down for less
frequent wipes.
d(Low Speed): Slow wipes.
a(High Speed): Fast wipes.
9(Off):Use to turn the wipers off.
When driving during the day and the
wipers are activated, the head
lamps automatically turn on after
completing eight wipe cycles.
Clear ice and snow from the wiper
blades before using them. If frozen
to the windshield, carefully loosen or
thaw them. Damaged blades should
be replaced.
Windshield Washer
The windshield wiper paddle is on
top of the turn signal lever.
L(Washer Fluid): Push the
paddle to spray washer fluid on the
windshield. The wipers will clear the
window and then either stop or
return to the preset speed.
{Warning
In freezing weather, do not use
the washer until the windshield is
warmed. Otherwise the washer
fluid can form ice on the
windshield, blocking your vision.
Compass
This vehicle may have a compass in
the Driver Information Center (DIC).
Compass Zone
Your dealer will set the correct zone
for your location.
Under certain circumstances, such
as during a long distance
cross-country trip or moving to a
new state or province, it will be
necessary to compensate for compass variance by resetting the
zone through the DIC if the zone is
not set correctly.
Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone
where you live, the compass may
give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
To adjust for compass variance, use
the following procedure:

Procedure
1. Do not set the compass zone
when the vehicle is moving. Only
set it when the vehicle is in
P (Park).

Lighting 6-3
There is a delay in the transition
between the daytime and nighttime
operation of the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The automatic headlamp
system is only affected when the
light sensor sees a change in
lighting lasting longer than the
delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes approximately 30 seconds
for the automatic headlamp system
to change if it is light outside. During
that delay, the instrument cluster
may not be as bright as usual. Make
sure the instrument panel brightness
control is in the full bright position.
SeeInstrument Panel Illumination
Control on page 6-4.Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to
P
or;to disable this feature.
Hazard Warning Flashers
|(Hazard Warning Flashers):
Press this button to make the front
and rear turn signal lamps flash on
and off. This warns others that you
are having trouble. Press again to
turn the flashers off.
When the hazard warning flashers
are on, the vehicle's turn signals will
not work.
Turn and Lane-Change
Signals
G(Turn Signals): An arrow on
the instrument cluster flashes in the
direction of the turn or lane change.
To signal a turn, move the lever all
the way up or down.

Driving and Operating 9-15
This position locks the ignition and
transmission.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steadypressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9-29.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
turn the ignition to ACC/
ACCESSORY.
{Caution
Using a tool to force the key to
turn in the ignition could cause
damage to the switch or break the (Continued)
Caution (Continued)
key. Use the correct key, make
sure it is all the way in, and turn it
only with your hand. If the key
cannot be turned by hand, see
your dealer.
2 (ACC/ACCESSORY): This is the
position in which you can operate
things like the radio and the
windshield wipers when the engine
is off.
3 (ON/RUN): This position can be
used to operate the electrical
accessories and to display some
instrument cluster warning and
indicator lights. This position can
also be used for service and
diagnostics, and to verify the proper
operation of the malfunction
indicator lamp as may be required
for emission inspection purposes.
The switch stays in this position
when the engine is running.

Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating. If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.

Vehicle Care 10-35
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.Fuses and Circuit
Breakers
The wiring circuits in the 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.
Engine Compartment
Fuse Block
The fuse block is located in the
engine compartment on the driver
side of the vehicle.
{Caution
Spilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
covers on any electrical
component.
