With the ignition on or in ACC/ACCESSORY,
move the windshield wiper lever to select
the wiper speed.
HI :Use for fast wipes.
LO : Use for slow wipes.
INT : Use for intermittent wipes or
Rainsense, if equipped and enabled. To
adjust wipe frequency, turn the band up for
more frequent wipes or down for less
frequent wipes. If Rainsense is enabled, see
“Rainsense” later in this section.

1x : For a single wipe, briefly move the
wiper lever down. For several wipes, hold
the wiper lever down. Clear snow and ice from the wiper blades
before using them. If frozen to the
windshield, carefully loosen or thaw them.
Damaged blades should be replaced. See
Wiper Blade Replacement
0269.
Heavy snow or ice can overload the wiper
motor.
{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.
{Warning
Before driving the vehicle, always clear
snow and ice from the hood, windshield,
washer nozzles, roof, and rear of the
vehicle, including all lamps and windows.
Reduced visibility from snow and ice
buildup could lead to a crash.
Wipe Parking
If the ignition is turned off while the wipers
are on LO, HI, or INT, they will
immediately stop. If the windshield wiper lever is then moved
to OFF before the driver door is opened or
within 10 minutes, the wipers will restart
and move to the base of the windshield.
If the ignition is turned off while the wipers
are performing wipes due to windshield
washing or Rainsense, the wipers continue
to run until they reach the base of the
windshield.
Rainsense
If equipped with Rainsense, a sensor located
near the top center of the windshield
detects the amount of water on the
windshield and automatically controls the
frequency of the windshield wiper.
When Rainsense is enabled, the normal
intermittent control operates as a sensitivity
control.
Keep this area of the windshield clear of
debris to allow for best system performance.

Lighting 121
There is a light sensor on top of the
instrument panel. Do not cover the sensor;
otherwise the headlamps will come on when
they are not needed.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
When it is bright enough outside, the
headlamps will turn off or may change to
Daytime Running Lamps (DRL).
The automatic headlamp system turns off
when the exterior lamp control is turned to
Oor the ignition is off.
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
Oor;to disable
this feature.
Adaptive Forward Lighting (AFL)
On vehicles with the AFL system, the
headlamps move horizontally while turning
the steering wheel to provide greater road
illumination in curves.
To activate AFL, set the exterior lamp
control to the AUTO or
2position.
To adjust the AFL setting, see Vehicle
Personalization 0109. Moving the control out of the AUTO or
2
position will deactivate the system.

272 Vehicle Care
Headlamp Aiming
Front Headlamp Aiming
Headlamp aim has been preset and should
need no further adjustment.
If the vehicle is damaged in a crash, the
headlamp aim may be affected.
If adjustment to the headlamps is necessary,
see your dealer.
Bulb Replacement
For the proper type of replacement bulbs,
or any bulb changing procedure not listed in
this section, contact your dealer.
Caution
Do not replace incandescent bulbs with
aftermarket LED replacement bulbs. This
can cause damage to the vehicle electrical
system.
LED Lighting
This vehicle has several LED lamps. For
replacement of any LED lighting assembly,
contact your dealer.
Electrical System
Electrical System Overload
The vehicle has fuses and circuit breakers to
protect against an electrical system
overload.
When the electrical load current 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.
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.
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.
