GO.
R If the KEYLESS-GO key has been removed
from the vehicle (e.g. if a passenger leaves
the vehicle with the KEYLESS-GO key):
- while someone is holding the Start/Stop
button or attempting to lock the vehicle
with the outer door handle, the message
Key not detected appears in the

in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo
which covers the rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic
conditions and could cause an accident.
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
glare mode if the ignition is switched on and
incident light from headlamps strikes the
sensor in the rear-view mirror.
The mirrors do not go into anti-glare mode if

ambient light, either the daytime running
lamps or the low-beam headlamps are
switched on.
If the low-beam headlamps are switched

instrument cluster light up.
If the light switch is set to $ or à , you
cannot switch on the high-beam headlamps.
Turn the light switch to L when driving at
night. You can switch on the high-beam
headlamps in this position.
With the engine running while the vehicle is
stationary (vehicles with automatic

switch off after 3 minutes if you shift the
selector lever to N or P from a driving
position.
With the engine running while the vehicle is
stationary: if you set the light switch to
T , the parking lamps and the low-beam
headlamps switch on.
Daytime running lamps in the USA
The daytime running lamps are deactivated
ex works on vehicles for the USA.XTo switch on the daytime running
lamps: switch on the "daytime running
lamps" function via the on-board computer
( Y page 206).XTurn the light switch to $ or à .

L indicator lamp in the instrument
cluster light up.
You can only switch on the high-beam
headlamps if there is little ambient light.
However, the headlamp flashers can always
be applied.
If you set the light switch to T or L
while the engine is running, the manual
setting overrides the daytime running lamps.
Automatic headlamps
GWarning!
If the light switch is set to Ã, the low-beam
headlamps will not come on automatically if
it is foggy. This could endanger you and
others. Therefore, turn the light switch to
L in fog.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
GWarning
In low ambient lighting or foggy conditions,
only switch from position à to L with
the vehicle at a standstill in a safe location.
Switching from à to L will briefly
switch off the headlamps. Doing so while
driving in low ambient lighting conditions may
result in an accident.
