INSTRUMENTS AND CONTROLS
138Dipped beam is always switched on when the rotating ring on the stalk switch is in position
when the car's electrical system is in igni-
tion position II or when the car is running.
Tunnel detection
The car detects when it is driven into a tunnel and switches from daytime running lights todipped beam. Note that the rotating ring in the left-hand stalk switch must be in
mode for tunnel detec-
tion to work.

Active main beamActive main beam is a function which uses a camera sensor at the top edge of the windscreento detect the headlamp beams from oncomingtraffic or the rear lights of vehicles in front, andthen switches from main beam to dipped beam.The function can also take streetlights intoaccount. Main beam is reactivated when the camera sen- sor no longer sees any oncoming vehicles orvehicles ahead.

If the active main beam has the on/off functional- ity25
then the lighting returns to main beam about
a second after the camera sensor no longer detects the headlamp beams from oncomingtraffic or the rear lights from vehicles in front. If the active main beam has adaptive functional- ity 25
then, unlike what happens during conven-
tional dimming, the light beam continues to illu- minate with main beam on both sides of oncom-ing traffic or vehicles ahead - only the part of thelight beam that points directly to the vehicle isdimmed.
Adaptive functionality: Dipped beam directly towards oncoming vehicle, but continued main beam on bothsides of the vehicle.
The lighting returns to full main beam about a second after the camera sensor no longerdetects the headlamp beams from oncomingtraffic or the rear lights from vehicles in front.
Activate/deactivate
The function can start while driving in the dark when the car's speed is approx. 20 km/h(12 mph) or higher. Activate/deactivate active main beam by turning the stalk switch's rotating ring to position
and release. If active main beam is deactivated while main beam is on, the lighting is immediatelyreset to dipped beam.
When active main beam is activated, the symbol
illuminates with a white glow in the driver
display. When main beam is activated, the symbol shines blue. This also applies for LED headlamps if themain beam is partially dimmed, i.e. if the lightbeam shines with slightly more than dippedbeam.

Manual operation
NOTE
Keep the windscreen surface in front of the camera sensor free from ice, snow, mist anddirt. Do not stick or attach anything to the wind- screen in front of the camera sensor as thismay reduce effectiveness or cause one ormore of the systems dependent on the cam-era to stop working.
If this symbol is shown in the driver dis- play, together with the message Active
High Beam Temporarily
unavailable, then switching between
main and dipped beam must be performed man- ually. The rotating ring on the stalk switch can still be in the
position. The symbol extin-
guishes when these message are shown.
The same applies if this symbol is shown together with the message
Windscreen sensor Sensor
blocked, see Owner's manual.
Active main beam may be temporarily unavailable e.g. in situations with dense fog or heavy rain.When active main beam becomes available again,or the windscreen sensors are no longer blocked, the message goes out and the
symbol illu-
minates.
WARNING
Active main beam is an aid for using the opti- mum beam pattern when conditions arefavourable. The driver always bears responsibility for man- ually switching between main and dippedbeam when traffic situations or weather con-ditions so require.
IMPORTANT
Examples of when manual switching between main and dipped beam may be required:
• In heavy rain or dense fog
• In freezing rain
• In snow flurries or slush
• In moonlight
• When driving in poorly lit built-up areas
• When the traffic ahead has weak lighting
• If there are pedestrians on or beside theroad
• If there are highly reflective objects suchas signs in the vicinity of the road
• When the lighting from oncoming trafficis obscured by e.g. a crash barrier
• When there is traffic on connecting roads
• On the brow of a hill or in a hollow
• In sharp bends.

Interior rearview mirror The interior rearview mirror can be dimmed with a control in the mirror's lower edge. Alternatively,the rearview mirror dims automatically.
Control for dimming
Manual dimmingBright light from behind could be reflected in the rearview mirror and dazzle the driver. Use dim-ming with the dimming control when lights frombehind are distracting:
1. Use dimming by moving the control in
towards the passenger compartment.
2. Return to normal mode by moving the control towards the windscreen.
Automatic dimming *Bright light from behind is automatically dimmed by the rearview mirror. The control for manualdimming is not available on mirrors with auto-matic dimming. The rearview mirror contains two sensors - one forward facing and one rearward facing - thatwork together to identify and eliminate dazzlinglight. The forward facing sensor detects ambientlight, while the rearward facing sensor detectsthe light from vehicle headlights behind.
NOTE
If the sensors are obscured by e.g. parking permits, transponders, sun visors or objects inthe seats or in the cargo area in such a waythat light is prevented from reaching the sen-sors, then the dimming function of the interiorrearview and door mirrors is reduced.
Automatic dimming is always active while driving, apart from when gearbox reverse position isselected. Dimming sensitivity can be adjusted inthree levels and will affect the interior rearviewand the door mirrors.
NOTE
When sensitivity is changed there is no imme- diately noticeable change in dimming, but thechange will be complete after a while.

Moisture sensor - in the casing by the inte- rior rearview mirror.
Outside temperature sensor - in the right- hand door mirror.
Sun sensor - on the upper side of the instru- ment panel.
Temperature sensor for the passenger com- partment - by the physical buttons in thecentre console.
NOTE
Do not cover or block the sensors with cloth- ing or other objects.
With the Interior Air Quality System * there is also

Perceived temperature
The climate control system regulates the climate in the passenger compartment based on theperceived temperature, not on actual tempera-ture.
The temperature you select in the passenger compartment corresponds to the physically per-ceived temperature as affected by factors suchas the ambient temperature, air speed, humidity,solar radiation, etc. in and around the car at thetime. The system includes a sun sensor which detects on which side the sun is shining into the passen-ger compartment. This means that the tempera-ture can differ between the right and left-handside's air vents despite the controls being set forthe same temperature on both sides.

Interior Air Quality System *
Interior Air Quality System (IAQS) is a fully auto- matic air quality system that separates gasesand particles to reduce the levels of odours andcontaminants in the passenger compartment.
IAQS is a part of the Clean Zone Interior Package (CZIP) and cleans the air in the passen-ger compartment from contaminants such as par-ticles, hydrocarbons, nitrous oxides and ground-level ozone. If the air quality sensor senses that the outside air is contaminated, the air intake is closed andair recirculation is activated.
NOTE
The air quality sensor must always be enabled to ensure the best air in the passenger com-partment. In a cold climate recirculation is limited so as to prevent misting. In the event of misting, the defrost functions for windscreen, side windows and rear win-dow should be used.
Activating/deactivating the air quality sensor
It is possible to set whether the air quality sensor should be activated/deactivated.
