mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can only be
activated when the low-beam headlamps are
switched on.
Active:
Rif you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif you are driving at speeds between 25 mph
(40 km/h) and 45 mph (70 km/h) and turn

The cornering lamp may remain lit for a short
time, but is automatically switched off after no
more than three minutes.
Cornering light function with traffic circle
function:
The cornering light function is activated on both
sides before entering a traffic circle through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the traffic circle. In this way, pedestrians
crossing the road, for example, are illuminated
by your vehicle in good time.
Only vehicles with the COMAND multimedia sys-
tem have this function.
Adaptive Highbeam Assist
General notes
You can use this function to set the headlamps
to change between low beam and high beam
automatically. The system recognizes vehicles
with their lights on, either approaching from the
opposite direction or traveling in front of your
vehicle, and consequently switches the head-
lamps from high beam to low beam.

If the wiper blades are worn, the windshield will
no longer be wiped properly. This could prevent
you from observing the traffic conditions.
Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiper blade
and it falls onto the windshield, the windshield
may be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
!To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehiclehas been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after several hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its per-
formance in the future.
RYou should therefore drive at varying vehicle
and engine speeds for the first 1000 miles
(1500 km).
RAvoid heavy loads, e.g. driving at full throttle,during this period.
RWhen changing gears manually, change up in
good time, before the tachometer needle rea-
ches Ôof the way to the red area of the tach-
ometer.
RDo not manually shift to a lower gear to brake
the vehicle.
RTry to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
RIdeally, for the first 1,000 miles (1,500 km),
drive in program E.
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
You should also observe these notes on break-
ing in if the engine or parts of the drive train on
your vehicle have been replaced.
Always observe the maximum permissible
speed.
Driving
Important safety notes
GWARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
When using floormats or carpets, make sure
that they are properly secured so that they do not slip or obstruct the pedals. Do not place
several floormats or carpets on top of one
another.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
