mends that you drive with the lights switchedon even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations.

R With the engine running: if you have acti-
vated the "Daytime running lamps" func-

The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's lighting at all times.

bility of your vehicle during the day. The day- time running lamps function is required by lawin Canada. It cannot therefore be deactivated.
When the engine is running and the vehicle is
stationary: if you move the selector lever from a drive position to P, the daytime running
lamps/low-beam headlamps go out after
three minutes.

stationary and in bright ambient light: if you
turn the light switch to T, you turn on the
daytime running lamps and parking lamps.
If the engine is running and you turn the light
switch to L, the manual settings take
precedence over the daytime running lamps.

headlamps switch on when the ignition is
switched on and the light switch is set to the L
position. This is a particularly useful
function in the event of rain and fog. X To switch on the low-beam headlamps:

comes to a standstill
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
above 6 mph (10 km/h) again after a full
brake application.
The hazard warning lamps still operate if the
ignition is switched off.
Adaptive Highbeam Assist
General notes
You can use this function to set the head-
lamps to change between low beam and high beam automatically. The system recognizes
vehicles with their lights on, either approach-
ing from the opposite direction or traveling in front of your vehicle, and consequently
switches the headlamps from high beam to
low beam.
Once the system no longer detects any other
vehicles, it reactivates the high-beam head- lamps.
The system's optical sensor is located behind the windshield near the overhead control panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognizeroad users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
