The hazard warning lamps still operate if
the ignition is switched off. Headlam
pcleaning system
The headlamps are cleaned automatically if
the "Wipe with washer fluid" function is oper-
ated ten times while the lights are on and the
engine is running (Y page 106). When you
switch off the ignition, the automatic head-
lamp cleaning syste mis reset and counting is
resumed from 0. Intelligent Light System
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 remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Active:
when the lights are switched on. 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 dipped-beam head-
lamps are switched on.
Active:
R
if you are driving at speeds below
40 km/h, the cornering light function is
activated either by the turn signal or by the
steering wheel being turned.
R if you are driving at speeds between
40 km/h and 70 km/h ,the cornering light
function is activated by the steering wheel
being turned.
Not active: if you are driving at speeds above
40 km/h or switch off the indicator lamp or
turn the steering wheel to the straight-ahead
position.
The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes. 102

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
available at the time of publicatio nofthe
Owner's Manual. Country-specific differen-
ces are possible. Please note that your
vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. Running-in notes

Risk of accident
New brake pads/linings only have optimal
braking performance after several hundred
kilometres. Until then, compensate for this by
applying greater force to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed. The first 1,500 km
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R Therefore, drive at varying speeds and
engine speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gear in good time, at the latest
when the rev counter needle is 2
/ 3 of the
way to the red area in the rev counter dis-
play.
R Do not manually shift to a lower gear to
brake the vehicle.
R if possible, do not depress the accelerator
pedal past the point of resistance (kick-
down).
R only select shift ranges 3,2or 1when driv-
ing slowly, e.g. in mountainous terrain.
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds. Additional running-in notes for AMG vehicles:
R
do not drive at speeds above 140 km/h for
the first 1,500 km.
R only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with rear axle locking
differential
Your vehicle is fitted with a self-locking dif-
ferential on the rear axle. Change the oil after
a running-in period of 3,000 km to improve
protection of the rear axle differential. This oil
change extends the service life of the differ-
ential. Have the oil change carried out at a
qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. Driving

G
Risk of accident
Do not place any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that it is correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Loose objects or the floormats could other-
wise get caught between the pedals if you
accelerate or brake suddenly. You will then
not be able to brake, declutch or accelerate
as intended. This could lead to accidents and
injury. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and 128
DrivingDriving and parking

the vehicle could skid. Thi
scould cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles: at low engine oil tempera-
tures (below +20 †), the maximum engine
speed is restricted in order to protect the
engine. To protect the engine and maintain
smooth engine operation, avoid driving at
full throttle when the engine is cold. Key positions

KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with
a key featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button.
The Start/Stop button must be inserted into
the ignition lock and the key must be in the
vehicle.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.

drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic lock-
ing feature (Y page 209).
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill starta ssist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll. G
Risk of accident
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.
X Take your foot off the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.

General notes The ECO start/stop function is only available
for the CLS 350 BlueEFFICIENCY and
CLS 63 AMG models.
AMG vehicles:
the ECO start/stop function
is only available in the Cdrive program.
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving.
The engine starts automatically when you pull
away again. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle. Driving

Risk of accident and injury
If the engine is switched off and the ECO sym-
bol is shown in green in the multifunction dis-
play, the engine has been switched off auto-
matically. All of the vehicle's systems remain active. If you open the door, unfasten your
seat belt or remove your foot from the brake
pedal, the engine will automatically start.T
he
vehicle may begin moving. You could suffer
serious or even fatal injury or cause an acci-
dent resulting in injury or death.
Never leave the vehicle while the ECO symbol
in the multifunction display is shown in green
or yellow. Always secure the vehicle against
rolling away before leaving it.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
Automatic engine switch-off The ECO start/stop function switches the
engine off automatically if the vehicle is
braked to a standstill and the brake remains
depressed with the transmission in position
D or N.
i You can still activate HOLD when the vehi-
cle is stationary, even if the engine has
been switched off automatically .Itis then
not necessary to continue applying the
brakes during the automatic stop phase.
When you depress the accelerator pedal,
the engine starts automatically and the
braking effect of the HOLD function is deac-
tivated. Depress the accelerator pedal
carefully, as the engine must be started
first.
The engine is only switched off if:
R the outside temperature is within the range
which is suitable for the system.
R the engine is at normal operating temper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged.
R the system detects that the windscreen is
not misted up when the air-conditioning
system is switched on.
R the bonnet is closed.
R the front door is closed and the seat belt is
fastened. 132
