WARNING
If head restraints are not installed and
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
Do not change over the head restraints for the
front and rear seats. Otherwise, it will not be
possible to correctly adjust the height and
angle of the head restraints.
Adjust the head restraint so that it is as close
as possible to the back of your head. Head restraint (example: luxury head restraint on

G
WARNING
Repeatedly switching on the seat heating can
cause the seat cushion and backrest pads to
become very hot. The health of persons with
limited temperature sensitivity or a limited
ability to react to excessively high tempera-
tures may be affected or they may even suffer
burn-like injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.
! When you leave your seat, do not place
anything on the seat and switch off the seat
heating. Do not switch the seat heating on
when the seat is not occupied, e.g. when
driving without a co-driver. The seat heat-
ing may otherwise overheat, causing dam-
age to the seat. The three red indicator lamps in the
0072
button show the activated heating level 1to
3.
The system automatically switches down
from level 3to level 2after approximately
five minutes.
The system automatically switches down
from level 2to level 1after approximately

do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt
before starting the engine. G

vehicle is in motion, it could change position
unexpectedly. This could cause you to lose
control of the vehicle. There is a risk of an
accident.
Before starting off, make sure the steering
wheel is locked. Never unlock the steering
wheel while the vehicle is in motion. G
WARNING
Children could injure themselves if they
adjust the steering wheel. There is a risk of
injury. When leaving the vehicle, always take the

WARNING
The additional mirrors in the exterior mirrors
reduce the size of the image. Objects visible
in the mirrors are closer than they appear. You
could misjudge the distance from road users
driving behind you when changing lanes, for
instance. There is a risk of an accident.

actual distance from road users driving
behind you, e.g.:
R by looking over your shoulder
R by looking in the main mirror in the exterior

tion of your vehicle's lighting system and, if
necessary, that of the trailer before each jour-
ney.

with Bi-Xenon headlamps)
The cornering lamps improve the illumination
of the road over a wide angle in the direction
you are turning, enabling better visibility in
tight bends, for example.
The cornering light function switches on
automatically, if:
R you are traveling at a speed of less than
25 mph (40 km/h) and you switch on a turn
signal or turn the steering wheel.
R you are traveling at a speeds of between
25 mph (40 km/h) and 43 mph (70 km/h)
and turn the steering wheel.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than 3 minute s.

opposite side of the vehicle switches on
instead. Hazard warning lamps
G
WARNING
The rear exterior light will be covered if you:
R open the rear doors by 90°
R open the rear dropside.
The vehicle will then be difficult for other road
users to see or will not be seen by them at all,
particularly if it is dark or visibility is poor.
There is a risk of an accident.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant national regulations, by using the warning tri-
angle, for instance. Hazard warning lamp switch

If you have indicated a turn while the hazard
warning lamps are switched on, only the turn
signal lamps on the side of the vehicle
selected will light up.
The hazard warning lamps switch on auto-
matically if:
R an air bag is deployed.
R you brake sharply and bring the vehicle to
a halt from a speed of more than 45 mph
(70 km/h).
If the hazard warning lamps have been
switched on automatically, press the 002F
hazard warning lamp switch to switch them
off.

The headlamps are cleaned automatically
with a high-pressure water jet if the "Wipe
with washer fluid" function is activated
(Y page 107) while the low-beam headlamps
are on and the engine is running.
Information on checking the washer fluid
level can be found in the "Maintenance and

Active light function
The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas will be illuminated to a
greater extent while driving. This allows you
to recognize pedestrians, cyclists and ani-
mals.
Active: when the lights are switched on. Highbeam Assist
General notes You can use this function to set the head-
lamps to change between high beam and low
beam automatically. The system recognizes
vehicles with their lights on, either approach-
ing from the opposite direction or traveling in
front of your vehicle, and consequently
switches the headlamps from high beam to
low beam.
Once the system no longer detects any other
vehicles, it reactivates the high-beam head-
lamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
Important safety notes G
WARNING
Highbeam Assist does not recognize road
users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Highbeam Assist may fail
to recognize other road users who have lights,
or may recognize them too late. In this or sim-
ilar situations, the automatic high-beam head-
lamps will not be deactivated or will be acti-
vated regardless. There is a risk of an acci-
dent. Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Highbeam Assist cannot take into account
road, weather or traffic conditions. Highbeam
Assist is only an aid. You are responsible for
adjusting the vehicle's lighting to the prevail-
ing light, visibility and traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or anything else cover-
ing the sensors
