Important safety notes G
WARNING
The vehicle's exhaust system may be very hot. You could burn yourself by touching the
exhaust system if you use HANDS-FREE
ACCESS. There is a risk of injury. Always
ensure that you only make the kicking move-
ment within the detection range of sensors.
! If the SmartKey is within the rear detec-
tion range of KEYLESS-GO, the following
situations, for example, could lead to the
unintentional opening of the trunk:
R using a car wash
R using a power washer
Make sure that the SmartKey is at least
10 ft (3 m) away from the vehicle.
General notes With KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the trunk lid
or stop the procedure without using your
hands. This is useful if you have your hands
full. To do this, make a kicking movement
under the bumper with your foot. Observe the following points:
R Carry your KEYLESS-GO key about your
person. The KEYLESS-GO key must be in
the rear detection range of the vehicle.
R When making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clear-
ance to the rear of the vehicle. You could
otherwise lose your balance e.g. on ice. R
Always ensure that you only make the kick-
ing movement within the detection range of
sensors 0043.
R Stand at least 12 in (30 cm) away from the
rear area while doing so.
R Do not come into contact with the bumper
while making the kicking movement. Oth-
erwise, the sensors may not function cor-
rectly.
R HANDS-FREE ACCESS does not function
when the engine is started.
R If a KEYLESS-GO key is within the rear
detection range of KEYLESS-GO, HAND-
FREE ACCESS could be triggered. The trunk
lid could thus be opened or closed unin-
tentionally, for example, if you:
- sit on the edge of the trunk.
- set something down or lift something up
behind the vehicle.
- polish the rear of the vehicle.
Do not carry the KEYLESS-GO key about
your person in these situations or in situa-
tions similar to these. This will prevent the
unintentional opening/closing of the trunk. 90

General notes
For reasons of safety, Mercedes-Benz recom- mends that you drive with the lights switchedon even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. Driving abroad
Symmetrical low-beam headlamps Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country where the vehicle is registered. This prevents
glare to oncoming traffic. When using sym-
metrical lights, the edge of the road is not lit
as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Asymmetrical low beam Have the headlamps converted back to asym-
metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after
crossing the border again. Setting the exterior lighting

causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
0058.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's lighting at all times.
Canada only:
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 0060, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light switch to 0058, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer
(Y page 243).
If the engine is running and you turn the light
switch to 0060or0058, the manual settings
take precedence over the daytime running
lamps.
0058 is the favored light switch setting. The
light setting is automatically selected accord- ing to the brightness of the ambient light
(exception: poor visibility due to weather con-
ditions such as fog, snow or spray):
R SmartKey in position 1in the ignition lock:
the parking lamps are switched on or off automatically depending on the brightness
of the ambient light.
R With the engine running: if you have acti-
vated the "daytime running lamps" function
via the on-board computer, the daytime
running lamps or the parking lamps and the
low-beam headlamps are switched on or off automatically depending on the brightnessof the ambient light.
X To switch on automatic headlamp
mode: turn the light switch to 0058.
Low-beam headlamps
Even if the light sensor does not detect that it is dark, the parking lamps and low-beam
headlamps switch on when the ignition is
switched on and the light switch is set to the 0058 position. This is a particularly useful
function in the event of rain and fog.
X To switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to
position 2or start the engine.
X Turn the light switch to 0058.
The green 0058indicator lamp in the instru-
ment cluster lights up.
Parking lamps ! If the battery has been excessively dis-
charged, the parking lamps or standing
lamps are automatically switched off to
enable the next engine start. Always park
your vehicle safely and sufficiently lit
according to legal standards. Avoid the
continuous use of the 0060parking lamps
for several hours. If possible, switch on the
0064 right or the 0063left standing lamp.
X To switch on: turn the light switch to 0060.
The green 0060indicator lamp in the instru-
ment cluster lights up.
Standing lamps
Switching on the standing lamps ensures the
corresponding side of the vehicle is illumina-
ted. Exterior lighting
121Lights and windshield wipers Z

The hazard warning lamps automatically
switch on if:
R an air bag is deployed or
R the vehicle decelerates rapidly from a
speed of above 45 mph (70 km/h) and
comes to a standstill
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
above 6 mph (10 km/h) again after a full
brake application.
The hazard warning lamps still operate if the
ignition is switched off. Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the direction you are turning, enabling better vis-
ibility in tight bends, for example. It can only
be activated when the low-beam headlamps
are switched on.
Active:
R if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
R if you are driving at speeds between
25 mph (40 km/ h)and 45 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 three minutes. Adaptive Highbeam Assist Plus
General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between low-beam, par-
tial high-beam and high-beam headlamps.
Partial high-beam is a form of illumination
whereby the high-beam is directed past other
road users. Other road users are kept out of
the high-beam. This prevents glare. When
there is a vehicle in front, for example, the
high-beam headlamps illuminate the areas to
its right and left, and the vehicle in front is
illuminated by the low-beam headlamps.
The system automatically adapts the low-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the high-beam headlamps.
If the high-beam or partial high-beam are
causing too much reflection from traffic
signs, the lights are automatically dimmed
and glare for the driver caused by the reflec-
tions is thus avoided.
The system's optical sensor is located behind the windshield near the overhead control
panel. Exterior lighting

WARNING
Adaptive Highbeam Assist Plus does not rec-
ognize 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 recognize road users who do
have lights, or may recognize them too late. In
this or similar situations, the automatic high-
beam headlamps will not be deactivated or
will be activated regardless. There is a risk of
an accident.
Always carefully observe the traffic conditions and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take
into account road, weather or traffic condi-
tions. Adaptive Highbeam Assist Plus is only
an aid. You are responsible for adjusting the
vehicle's lighting to the prevailing light, visi-
bility and traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
