Raise or lower the lever until the arrow starts to
ash to signal a lane change. Hold it there until the
lane change is complete. The lever returns to its
original position when it is released.
Rapid ashing of arrows when signaling for a turn
or lane change may be caused by a burned-out
signal bulb. Other driver’s will not see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs
if the arrow fails to work when signaling a turn.
SeeFuses and Circuit Breakers on page 487for
more information.

To turn the HUD image off, turn the knob
counter-clockwise.
Polarized sunglasses could make the HUD image
harder to see.
As light shines out from the HUD, it is possible for
light to shine back in. In rare occurrences,
when the sun is at a specic angle and position,
the sun’s rays can shine back into the HUD. When
this occurs, the display device within the HUD
will be temporarily illuminated. The event will end
when the vehicle’s angle to the sun changes.
Clean the inside of the windshield as needed to
remove any dirt or lm that reduces the sharpness
or clarity of the HUD image.
To clean the HUD, spray household glass cleaner
on a soft, clean cloth. Wipe the HUD lens gently,
then dry it.
Notice:When cleaning, be careful not to
scratch the HUD or camera lenses. Do
not spray glass cleaner directly on the HUD
lens because the cleaner could leak inside the
unit and cause damage.
If the ignition is on and you cannot see the HUD
image, check to see if:
Something is covering the HUD unit.
The brightness is adjusted properly.
The HUD image is adjusted to the
proper height.
Ambient light in the direction your vehicle is
facing is low.
A fuse is blown. SeeFuses and Circuit
Breakers on page 487.
Keep in mind that your windshield is part of the
HUD system. SeeWindshield Replacement
on page 419.
The following Adaptive Cruise Control message
may appear in the HUD:
PEDAL APPLIED ACC OVERRIDE:This
message indicates that you are pressing your
foot on the accelerator pedal and overriding
Adaptive Cruise Control. While you are doing
this, the system will not automatically apply the
brakes. Once you remove your foot from the
accelerator pedal, Adaptive Cruise Control will
return to normal operation and be able to apply
the brakes, if needed.
You may also see an Adaptive Cruise Control
active symbol, alert symbol or vehicle ahead
symbol. SeeAdaptive Cruise Control on page 197
for more information.

Certain accessory power plugs may not be
compatible to the accessory power outlet and
could result in blown vehicle or adapter fuses. If
you experience a problem, see your dealer
for additional information on the accessory
power outlets.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
Follow the proper installation instructions that are
included with any electrical equipment you install.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and
cigarette lighter.
Notice:If you put papers, pins, or other

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 78.
Headlamp Wiring
The headlamp wiring is protected by fuses in the
fuse block. An electrical overload will cause
the lamps to turn off. If this happens, have your
headlamp wiring checked right away.
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.
486

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 xed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
This greatly reduces the chance of res 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. Just 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 three fuse blocks.
One is located in the engine compartment, on the
passenger’s side of the vehicle, and the other
two are located under the rear seat on both the
driver’s and passenger’s side of the vehicle.
487

The underhood fuse block is located in the front of
the engine compartment on the passenger’s
side of the vehicle. SeeEngine Compartment
Overview on page 373for more information
on location and removal procedure for the front
compartment underhood sights shields.
To access the fuses, push in the tabs located on
each side of the fuse block cover, then lift the
cover off.

{CAUTION:
A safety belt that is not properly routed
through the seat cushion or is twisted will
not provide the protection needed in a
crash. If the safety belt has not been
routed through the seat cushion at all, it
will not be there to work for the next
passenger. The person sitting in that
position could be badly injured. After
reinstalling the seat cushion, always
check to be sure that the safety belts are
properly routed and are not twisted.
1. Buckle the center passenger position safety
belt, then route the safety belts through the
proper slots in the seat cushion. Do not let the
safety belts get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear-locating guides hook into
the wire loops on the back frame.3. With the seat cushion lowered, push rearward
and then press down on the seat cushion until
the spring locks on both ends engage.
4. Check to make sure the safety belts are
properly routed and that no portion of any
safety belt is trapped under the seat.
Also make sure the seat cushion is secured.
Rear Underseat Fuse Block
There is a fuse block located under the rear seat
on the driver’s side and passenger’s side of
the vehicle. The rear seat cushion must be
removed to access the fuse blocks. See
“Removing the Rear Seat Cushion” listed
previously in this section.
To access the fuses, push in the two tabs, then lift
the cover off.
