The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle'slighting at all times. Ã is the favored light switch setting. The
light setting is automatically selected accord- ing to the brightness of the ambient light
(exception: poor visibility due to weather con-
ditions such as fog, snow or spray):
R SmartKey in position 1in the ignition lock:
the parking lamps are switched on or off
automatically depending on the brightness
of the ambient light.
R With the engine running: if you have acti-
vated the daytime running lamps function
via the on-board computer, the daytime
running lamps or the low-beam headlamps
and parking lamps are switched on or off
automatically depending on the brightnessof the ambient light.
X To switch on automatic headlamp mode: turn the light switch to Ã.
Only for Canada:
The daytime running lamps improve the visi-
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.
When the engine is running, the vehicle is
stationary and in bright ambient light: if you
turn the light switch to T, the daytime
running lamps and parking lamps switch on.
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( Y page 205). If the engine is running and you turn the light
switch to TorL , the manual settings
take precedence over the daytime runninglamps.
Low-beam headlamps
GWARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
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 .
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
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:
turn the SmartKey in the ignition lock to position 2or start the engine.
X Turn the light switch to L.
The green Lindicator lamp in the instru-
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
with the parking lamps and low-beam head-lamps. X To switch on the front fog lamps: turn
the SmartKey in the ignition lock to position
2 or start the engine.
X Turn the light switch to Lorà .
