* Option/accessory.157
With the steering wheel lever's lighting ring in the
position, the daytime running lights (DRL
1
)
will illuminate when the vehicle is driven in day- light conditions. The headlights will switch auto-matically from daytime running lights to lowbeams in weak daylight or dark conditions. Theheadlights will also switch to low beams if the front fog lights * and/or rear fog light are acti-
vated. US models : When
mode is selected, the
daytime running lights can be deactivated in the center display. The parking lights will also bedeactivated. In weak daylight or dark conditions,the parking lights and low beams will be illumi-nated. In the US: With the lighting ring in the
or
position, the daytime running lights will be
off .
In Canada : With the lighting ring in the
or
position, the daytime running lights will be
on.
NOTE
Volvo recommends use of Daytime Running Lights in the US. Its use is mandatory in Can-ada.
WARNING
The system is an energy saving aid – it cannot in all situations determine when the daylight istoo weak or not strong enough, e.g. whenthere is fog or rain. The driver is always responsible for driving the vehicle with lighting that is safe for the trafficconditions and as specified by applicable traf-fic regulations.

Low beams
When driving with the lighting ring in the
position, low beam will be automatically acti- vated in weak daylight or dark conditions, whenthe ignition is in II position or when the engine is
running.

Active high beam
Active high beams is a function that uses cam- era sensors in the upper edge of the windshieldto detect the headlights of approaching vehiclesor the taillights of the vehicle directly ahead.When either of these is detected, the vehicle'sheadlights will automatically switch from highbeams 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 anapproaching vehicle or a vehicle ahead, the head-lights will return to high beams. This function can be used in dark conditionswhen 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 highbeams are partially dimmed, i.e. if the headlightsare illuminated with slightly more than low beams.
Vehicles with halogen headlights
When the camera sensor no longer detects the headlights of approaching vehicles or the tail-lights of a vehicle ahead, the headlights willreturn to high beams after a second or so.
Vehicles with LED3 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. Whenactive high beams become available again, or thewindshield 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 whentraffic situations or weather conditions requirethis.

Active Bending Lights *
Active Bending Lights (ABL) are designed to help provide maximum illumination in curves andintersections. Depending on equipment level, vehicles with LED 5
headlights * may be equipped
with Active Bending Lights.
Headlight pattern with function deactivated (left) and activated (right).
Active Bending Lights follow the movement of the steering wheel to help provide maximum illu-mination in curves and intersections, improvingvisibility for the driver. The function is automatically activated when the engine is started. If a fault is detected in the sys- tem, the
symbol will illuminate in the
instrument panel and a message will be dis- played. The function is only active in weak daylight ordark conditions and only when the vehicle is mov-ing and the low beams are on.
Deactivating/activating the functionThe function is activated as the default factorysetting and can be activated and deactivated inthe center display's Function view:

Lift the rubber strip by pressing it inward into the engine compartment.
Remove the plastic cover by folding out the catch and lifting the cover upward.
Unscrew the expansion tank cap and fill coolant as needed. The level should be between the MIN and MAX marks on the
expansion tank.
CAUTION
• Mix the coolant with water of acceptable quality. If you are unsure of the quality ofthe water, use a Volvo-recommendedpremixed coolant.
• Make sure the coolant mixture is 50%water and 50% coolant.
• Only use coolants with corrosion protec-tion recommended by Volvo.
• To help ensure sufficient corrosion pro-tection in the system, only use new cool-ant when replacing larger components inthe cooling system.
• Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
• High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

Replacing bulbs
The bulbs in the halogen headlights can be changed without the help of a workshop. Halogen headlights are not available on all mod- els and markets. Contact a Volvo retailer formore information. LED 13
bulbs must be replaced by a workshop.
An authorized Volvo workshop is recommended.
NOTE
For information on lights not mentioned in this article, contact a Volvo dealer or a certi-fied Volvo service technician.
The headlight bulbs can be replaced without the assistance of a workshop, but before a bulb canbe replaced, the plastic cover over the headlightneeds to be removed. The low beam lights will be accessible when the headlight's round rubber cover has beenremoved. The bulbs of the turn signals, high beam and day- time running lights/parking lights are accessibleonce the rectangular headlight cover has beenremoved.

MAINTENANCE AND SERVICE
* Option/accessory.
592 If you are experiencing problems with any lights other than light bulbs, contact a workshop
14
. If
there is a problem with an LED 13
light, the entire
lamp unit will normally need to be replaced.
WARNING
The vehicle electrical system must be in igni- tion mode 0 when bulbs are replaced.
CAUTION
Never touch the bulb glass with your bare fin- gers. Grease and oils from your fingers vapor-ize in the heat and will leave a deposit on thereflector, which may damage it.
NOTE
If the error message persists after the defec- tive bulb has been replaced, we recommend avisit to an authorized Volvo workshop.
NOTE
Exterior lighting such as headlights and tail- lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
NOTE
Bulbs for active curve lighting * contain traces
of mercury and should therefore always be submitted to a certified Volvo service techni-cian.
