causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.

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

bility of your vehicle during the day. To do this,
