Automatic headlamp mode

G WARNING
When the light switch is set to Ã, the low-

causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
L.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.

Canada only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day-
time running lamps function is required by law
in 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.
When the engine is running, the vehicle is
stationary and in high ambient light bright-
ness: if you turn the light switch to T, you
turn on the daytime running lamps and park-
ing lamps.
If the engine is running and you turn the light
switch to L, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer
( page 216).

If the engine is running and you turn the light
switch to T or L, the manual settings

lamps.

Low-beam headlamps

Even if the light sensor does not detect that it
is dark, the parking lamps and low-beam
headlamps switch on when the ignition is

function in the event of rain and fog.
To switch on the low-beam headlamps:

ment cluster lights up.

Front fog lamps

In conditions where visibility is poor due to
fog, snow or rain, the fog lamps improve vis-
ibility as well as making it easier for other road
users to see you. They can be operated
together with the parking lamps or together

lamps.
