Highway light function* (vehicles with LED
headlights) -this function adapts the lighting
for highway driving based on vehicle speed.
.&_ WARNING
- Automatic headlights are only intended
to assist the driver. They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights §.0
under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see the road ahead and when you cannot be
seen by other motorists. Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.
- Please observe legal regulations when
using the lighting systems described.
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
@ Tips
- The light sensor* for automatic dynamic
headlight range control* is located in the
rear view mirror mount. You should
therefore not apply any stickers to the
windshield in this area in order to pre­
vent malfunctions or failures .
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display¢
page 22 .
- You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after switching them on. This does not affect
the service life of the lighting.
Emergency flasher
The emergency flasher makes other motorists
aware that you or your vehicle ore in an emer ­
gency situation.

The emergency flashers will turn on automati­
cally if you are in an accident where the airbag

(D Tips
You should turn on the emergency flashers
when:
- you are the last vehicle standing in a traf­
fic jam so that any other vehicles coming
can see you, or when
- your vehicle has broken down or you are
in an emergency situation, or when
-your vehicle is being towed by a tow
truck or if you are towing another vehicle
behind you.

Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed .
The speed warning system warns you if you
are exceeding the maximum speed that you
have set . You will hear a warn ing tone when
your speed exceeds the stored value by ap­
p rox imately 3 mph (3 km/h) . An indicato r
l ig ht . (USA models)/ . (Canada mode ls) i n
the ins trumen t clus ter display also t urns on at
the same time . The ind icator light
a;m
turns off when the speed decreases below the
stored maximum speed.
Se tting a thresho ld is re commended if yo u
wo uld like to be reminded when you reach a
certain maximum speed. Situations where you may want to do so include driv ing in a country
with a general speed Limit or if there is a
specified max imum speed for winter tires .
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should st ill watch the speedome
ter to ma ke s ure you
are not dr iving faster than the speed limit .
Setting the threshold
You can set, chang e and delet e the threshold
in the MMI.
• Select: I CAR I func tion button > Car sy stem s
contro l but to n > Driver a ssist > Speed warn­
ing .
You can set any threshold betwee n 20 mph
(30 km/h) and 150 mph (2 40 km/h). Se tting s
can each be adj usted in incremen ts of
5 mph
(10 km/h).

t he type of d isplay in your vehicle.
The speed is k ept constant via an engine out­

A WARNING
-Always pay attention to traffic even when
the cruise control is switched on . You are
always responsible for your speed and
the distance between your vehicle and other vehicles.
- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traff ic, on twisting roads and
when road conditions are poor (such as
ice, fog, grave l, heavy rain and hydro ­
planing) -risk of accident .
- Turn off the cruise control temporari ly
when entering turn lanes, highway exit lanes or in construction zones.
- Please note that inadvertently "rest ing "
yo ur foot on the accelerator peda l causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acce leration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is sw itched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light
[~jlQ~i4 (US models) I ii (Canad ian mod­
