.
WARNING
Adjust the steering wheel and fix it before driving away.
With speed related power steering the level of steering force can be adjusted. Steering force isregulated according to the car's speed in order togive the driver enhanced road responsiveness.
With knee airbag
Adjusting the steering wheel.
1. Push the lever forwards to release the steer- ing wheel. 2. Adjust the steering wheel to the position that
suits you.
3. Pull the lever back to fix the steering wheel in place. If the lever is stiff, press the steering wheel lightly at the same time as you movethe lever back.
Without knee airbag
Adjusting the steering wheel.
1. Pull the lever backwards to release the steer-ing wheel.
2. Adjust the steering wheel to the position that suits you.
3. Push the lever forwards to secure the steer- ing wheel. If the lever is stiff, press the steer- ing wheel lightly at the same time as youmove the lever back.

WARNING
The car's audio system is not able to deter- mine when daylight is too weak or sufficientlystrong, e.g. in fog and rain, in all situations. The driver is always responsible for ensuring that the car is driven with a beam pattern suit-able for the traffic situation and in accordancewith applicable traffic regulations.
Thumbwheel in the instrument panel
Thumbwheel for adjusting interior brightness
Thumbwheel for headlamp levelling
A car with LED 21
headlamps * has automatic
headlamp levelling and therefore does not have the thumbwheel for headlamp levelling.
Adjusting the interior brightness
The lamps inside the car come on differently depending on the ignition position used. The thumbwheel adjusts the brightness of display lighting, control lighting, ambient light and ambi- ence light *.
Headlamp levelling
The load in the car changes the vertical align- ment of the headlamp beam, which could dazzleoncoming motorists. Avoid this by adjusting theheight of the beam. Lower the beam if the car isheavily laden. For different load cases and settings, see the section "Headlamp levelling".

Headlamp levelling
Headlamp levelling 22
is adjusted using one of
the thumbwheels in the instrument panel.
1. Leave the engine running, or have the car's
electrical system in ignition position I.
2. Roll the thumbwheel up/down to raise/lower beam alignment.
The position in which the thumbwheel should be set for a number of load cases is shown below.

Daytime running lights The daytime running lights are switched on when the rotating ring on the stalk switch is in position
, or as well as when
the car's electrical system is in ignition position II
or when the car is running. For the
posi-
tion, this only applies in daylight. In weak daylight or darkness, dipped beam is switched oninstead.
Daytime running lights during the day.
DRL
Stalk switch rotating ring in AUTO position.
If the stalk switch rotating ring is in the position, the daytime running lights (Daytime Running Lights - DRL) are switched on when thecar is driven in daylight. The car automaticallychanges lighting from daytime running light todipped beam in weak daylight or darkness. Changing to dipped beam also takes place if thefront fog lamp and/or rear fog lamp are activated. At
stationary when the car is running, the posi-
tion lamps are switched on instead of other light- ing, if the rotating ring is moved to the position for position lamps,
, from another position .
WARNING
This system help to save energy - it cannot determine in all situations when daylight is tooweak or sufficiently strong, e.g. in mist andrain. The driver is always responsible for ensuring that the car is driven with the correct beampattern for the traffic situation and in accord-ance with applicable traffic regulations.

Dipped beam
When driving with the stalk switch's rotating ring in the
position, dipped beam is activated
automatically in weak daylight or darkness.
Stalk switch rotating ring in AUTO position.
With the stalk switch's rotating ring in the position, dipped beam is activated automatically in weak daylight or darkness, when the car's electrical system is in ignition position II or when
the car is running. With the stalk switch's rotating ring in
position, dipped beam is also activated automati- cally if:
• the front fog lamps
* are activated
• the rear fog lamp is activated
• the front and rear fog lamps are activated

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.
