Adaptive Highbeam Assist Plus
General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illumination is a form of illu-
mination whereby the main beam is directed
past other road users. Other road users are kept
out of the main beam. This prevents glare. If
there is a vehicle in front, for example, the main- beam headlamps illuminate the areas to its right
and left, and the vehicle in front is illuminated by
the dipped-beam headlamps.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system no
longer detects any other vehicles, it switches on the main-beam headlamps again.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from traf-fic signs, the lights are automatically dimmed
and glare for the driver caused by the reflections
is thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Vehicles with drive program S+(Sport Plus): the
speed at which Adaptive Highbeam Assist Plus
switches between full beam and dipped beam is
increased when the drive program is switched
on.
Important safety notes G
WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise 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, Adaptive Highbeam Assist
Plus may not recognise road users who do
have lights, or may recognise them too late. In this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent. Always carefully observe the traffic conditions
and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist Plus is only an aid.
You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and traf-
fic 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 if the sensors are
obscured

The _ indicator lamp in the multifunction
display lights up when it is dark and the light
sensor switches on the dipped-beam head-
lamps.
At speeds above approx.25 km/h: the
headlamp range is automatically controlled
according to the distance to other road users.
At speeds above approx.30 km/h:
R if no other road users are detected, the
main-beam headlamps are automatically
switched on
R if other road users are detected, the partial
main-beam headlamps are automatically
switched on
The K indicator lamp in the instrument
cluster also lights up.
At speeds below approx.25 km/hor when
there is sufficient street lighting:
R the partial main-beam headlamps are
switched off automatically
R the main-beam headlamps are switched off
automatically 124

control
Optimum use of the automatic climate
control The following contains notes and recommenda-
tions on how best to use THERMATIC automatic climate control or THERMOTRONIC.
R Activate climate control using the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Vehicles with THERMOTRONIC:in auto-
matic mode, you can also use the ñbutton
to set a climate mode (FOCUS/MEDIUM/
DIFFUSE). The MEDIUM level is recommen-
ded.
R Set the temperature to 22 †.
R Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use air-recirculation mode only briefly, e.g. if
there are unpleasant outside odours or when
in a tunnel. The windows could otherwise mist up as no fresh air is drawn into the vehicle in
air-recirculation mode. R
Vehicles with THERMOTRONIC:use the
ZONE function to adopt the temperature set-
tings on the driver's side for the front-
passenger side and the rear compartment as well. The indicator lamp above the ábut-
ton goes out.
R Vehicles with THERMOTRONIC:use the
"residual heat" function if you want to heat or
ventilate the vehicle interior when the ignitionis switched off. The residual heat function can
be activated or deactivated only with the igni- tion switched off.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control operates only at a reduced capacity. If
you require the full climate control output, you
can switch off the ECO start/stop function by
pressing the ECO button (Y page 153).134

General notes The rear window heating has a high current
draw. You should therefore switch it off as soon
as the window is clear. It otherwise switches off automatically after several minutes.
If the battery voltage is too low, the rear window
heating may switch off.

Problems with the rear window heating Problem
Possible causes/consequences and
M MSolutions The rear window heating
has switched off prema-
turely or cannot be
switched on. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heating
can be switched on again. Activating/deactivating air-recircula-
tion mode
General notes You can deactivate the flow of fresh air tempo-
rarily if unpleasant odours are entering the vehi-
cle from outside. The air already inside the vehi- cle will then be recirculated.
If you switch on air-recirculation mode, the win-
dows can mist up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from mist- ing up. Switching on/off X
Turn the key to position 2in the ignition lock
(Y page 148).
X To activate: press thedbutton.

i In the event of high pollution levels
(THERMOTRONIC automatic climate control
only) or at high outside temperatures, air-
recirculation mode is automatically activated.
When air-recirculation mode is activated
automatically, the indicator lamp in the d
button is not lit. 138
Operating the climate cont
rol systemClimate control

The remote control has a range of approximately
300 metres. This range is reduced by:
R sources of radio interference
R solid objects between the remote control and
the vehicle
R the remote control being in an unfavourable
position in relation to the vehicle
R transmitting from an enclosed space
If the remote control battery is low, the battery

WARNING
Batteries contain toxic and corrosive substan- ces. If batteries are swallowed, it can result in
severe health problems. There is a risk of fatal injury.
Keep batteries out of the reach of children. If
a battery is swallowed, seek medical attention immediately. H
Environmental note Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and disposed of in anenvironmentally responsible
recycling system. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop or to a col-
lection point for used batter-
ies.
Replacing the battery If the battery needs to be replaced, the battery
symbol on the left of the display is shown as

General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (Y page 253).
It is only possible to shift the transmission from position Pto the desired position if you depress
the brake pedal. Only then is the parking lock
released. If you do not depress the brake pedal,
the DIRECT SELECT lever can still be moved but the parking lock remains engaged.
i Upshifts take place at higher engine speeds
after a cold start. This helps the catalytic con- verter to reach its operating temperature
more quickly.
