LIGHTING
154Parking lights
The parking lights can be used to help other
road users see the vehicle if it is stopped or
parked. Use the lighting ring on the steering
wheel lever to turn on the parking lights.
Lighting ring in the parking light position.
Turn the lighting ring to the position to
turn on the parking lights (the license plate light-
ing will also illuminate).
Canadian models: If the ignition is in the II posi-
tion or the engine is running, the daytime running
lights will illuminate instead of the front parking
lights. With the lighting ring in this position, the
parking lights will remain on regardless of what
position the ignition is in.
US models: When mode is selected, the
daytime running lights can be deactivated in the
center display. The parking lights will also be deactivated. In weak daylight or dark conditions,
the parking lights and low beams will be illumi-
nated.
In dark conditions, the rear parking lights also
illuminate when the tailgate is opened to alert fol-
lowing traffic. This happens regardless of what
position the lighting ring or ignition is in.

The vehicle has sensors that detect ambient
lighting conditions. With the lighting ring in the position, the daytime running lights will
always be activated when the ignition is in mode

or dark conditions, the headlights automatically
switch to low beams. Lighting ring in AUTO position.

Active high beam
Active high beams is a function that uses cam-
era sensors in the upper edge of the windshield
to detect the headlights of approaching vehicles
or the taillights of the vehicle directly ahead.
When either of these is detected, the vehicle's
headlights will automatically switch from high
beams to low beams. Active high beam is enabled by moving the lighting ring
on the steering wheel lever to
.
The function can also detect street lighting.
When the camera sensor no longer detects an
approaching vehicle or a vehicle ahead, the head-
lights will return to high beams. This function can be used in dark conditions
when the vehicle's speed is approx. 20 km/h
(approx. 12 mph) or higher.
If active high beams are deactivated when the
high beams are on, the headlights will automati-
cally switch to low beams.
When active high beams are activated, a white symbol will be displayed in the instrument
panel.
When high beams are on, the symbol will be blue.
For LED headlights, this applies even if the high
beams are partially dimmed, i.e. if the headlights
are illuminated with slightly more than low beams.
Vehicles with LED 3
headlights*
If the active high beams are equipped with the
auto on/off function 4
, the headlights will return to
high beams a second or so after the camera sen-
sor no longer detects the headlights of approach-
ing vehicles or the taillights of a vehicle ahead.
Limitations for active high beams
The camera sensor on which the function is
based has limitations. If this symbol and the message Active
High Beam Temporarily unavailable is displayed in the instru-
ment panel, switching between high
and low beams must be done manually. The light-
ing ring on the steering wheel lever can remain in
the position. The symbol will go out
when the message is displayed. The same applies if this symbol along
with the message
Windscreen
sensor Sensor blocked, see Owner's manual is displayed. Active high beams may be temporarily unavailable
in certain situations, e.g. heavy fog or rain. When
active high beams become available again, or the
windshield sensors are no longer blocked, the
message will disappear and the
symbol will
be displayed.
WARNING Automatic high beam is an aid in using the
best possible light based on prevailing condi-
tions.
The driver is always responsible for manually
switching between high and low beam when
traffic situations or weather conditions require
this.

dimming function
Bright light entering the vehicle from behind, e.g.
from the headlights of following vehicles, could
reflect in the rearview mirror and door mirrors
and cause a glare. Use the dimming function
when light from behind is distracting.
Auto-dimIf bright light enters the vehicle from behind, the
door mirrors will automatically dim. Auto-dim is
always active when the engine is running, except
when reverse gear is engaged.
NOTE When the level of sensitivity is changed, this
change will not be noticeable immediately but
will instead take effect after a short period of
time.
The sensitivity level for dimming will affect both
the rearview mirror and door mirrors.

3. Under Rearview Mirror Auto Dimming ,
select
Normal, Dark or Light.
The rearview mirror instead has two sensors -
one pointing forward and one pointing rearward -
which work together to identify and eliminate glare. The forward-pointing sensor monitors
ambient light, while the rearward-pointing sensor
monitors light from the headlights of following
vehicles.
For the door mirrors to be equipped with auto-
dim, the rearview mirror must also be equipped
with auto-dim.
NOTE
If the sensors are obstructed by e.g. a parking
permit, transponder, sunshade or objects on
the seats or in the cargo compartment in a
way that prevents light from reaching the sen-
sors, the auto-dim function in the door and
rearview mirrors will be reduced.
