Lighting 161
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.
Adaptive Forward
Lighting (AFL)
If equipped, the AFL pivots the
headlamps horizontally to provide
greater road illumination while
turning. To enable AFL, set the
exterior lamp control to the AUTO
position. Moving the switch out of
the AUTO position deactivates the
system. AFL operates when the
vehicle speed is greater than 3 km/h
(2 mph). AFL does not operate
when the transmission is in
R (Reverse). AFL is not immediately
operable after starting the vehicle;
driving a short distance is required
to calibrate the AFL. See Exterior
Lamp Controls 0159.
LED Headlamp System
This system automatically controls
the LED headlamps light intensity
and distribution based on the
lighting condition, road type, and
driving situation. The vehicle adapts
the headlamps automatically to
enable optimal lighting while driving.
The Intelligent Light Distribution
feature can be enabled or disabled. See
“Adaptive Forward Lighting”
under Vehicle Personalization
0 150.
The following lighting functions are
available when the exterior lamp
control is in the AUTO or
5
position.
Curve Lighting
Certain LEDs turn on automatically
to improve lighting in curves. This is
based on the steering wheel
position and vehicle speeds from
40 km/h (25 mph) to 70 km/h
(43 mph).
Corner Lighting
If equipped with cornering lamps,
certain LEDs automatically come on
when all of the following occur:
. The turn signals are activated or
the steering wheel is at a
calibrated angle.
. The vehicle is traveling up to a
speed of 40 km/h (25 mph).

sensor to automatically detect high
humidity inside the vehicle. When
high humidity is detected, the
climate control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation.

Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:1. Ease off the accelerator and then, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge. 3. Turn the steering wheel to go
straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —
too much speed or steering in a
curve causes tires to slip and
lose cornering force.
. Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions: .
Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
. Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues —such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
. Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
