Requirements
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica- tion, e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g. a
cushion. The entire base of the child restraint
system must always rest on the seat cushion of
the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as flat as possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation and operating
instructions.
Operation of Occupant Classification
System (OCS) 0043
PASSENGER AIR BAG ON indicator lamp
0044 PASSENGER AIR BAG OFF indicator lamp The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
X Press the Start/Stop button once or twice, or
turn the SmartKey to position 1or 2in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy in the event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
If the status of the front-passenger front air bag
changes while the vehicle is in motion, an air bag display message appears in the instrument clus-
ter (Y page 176). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front air bag both before and during the journey. G
WARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
R the classification of the person in the front-
passenger seat is correct and the front- 46
Occupant safetySafety

vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Please pay special attention to the
notes on tires, recommended minimum tire
tread depths, etc. (Y page 257).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible. ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when braking.
The 0025 ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 58). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 193) and dis-play messages which may be shown in the
instrument cluster (Y
page 168).
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
X To make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a reminder to take extra care while driving. BAS (Brake Assist System)
General information BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 58). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you

As a result, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist might:
R intervene unnecessarily
R not intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
Due to the nature of the system, complex but
non-critical driving conditions may also cause
Active Brake Assist to intervene.
Even if Active Brake Assist is not available due to a malfunction in the radar sensor system, the
brake system is still available with full brake
boosting effect and BAS. ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 58).
ESP ®
monitors driving stability and traction, i.e.
power transmission between the tires and the
road surface.
If ESP ®
detects that the vehicle is deviating from
the direction desired by the driver, one or more
wheels are braked to stabilize the vehicle. The
engine output is also modified to keep the vehi- cle on the desired course within physical limits.
ESP ®
assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilize
the vehicle during braking. ETS (Electronic Traction System) i
Observe the "Important safety notes" sec-
tion (Y page 58).
ETS traction control is part of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is transfer-
red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP ®
.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 58). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further driv- ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
When towing your vehicle with the front axle
raised, observe the notes on ESP ®
(Y page 253).
When towing the vehicle with the rear axle
raised, observe the notes on ESP ®
(Y page 254).
If the 00BB ESP®
OFF warning lamp lights up
continuously, ESP ®
is deactivated.
If the 00E5 ESP®
warning lamp and the 00BB
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 195) and display messages which may
be shown in the instrument cluster
(Y page 168).
Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly. 62

ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also has
the HOLD function (Y page 138) and hill start
assist (Y page 111). STEER CONTROL
General information STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilization.
This steering assistance is provided in particular if:
R both right wheels or both left wheels are on a
wet or slippery road surface when you brake
R the vehicle begins to skid
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 58).
No steering assistance is provided from STEER
CONTROL, if:
R ESP ®
is malfunctioning
R the steering is malfunctioning
If ESP ®
is malfunctioning, you will be assisted
further by the electrical power steering. Recuperative Brake System
G
WARNING
In the event of malfunctions in the Recupera- tive Brake System, the following may occur: R
the braking performance of the electric
motor may be either reduced or not effec-
tive
R brake pedal resistance may be lower than
usual
R pedal travel may be longer than usual
If you do not make an additional effort to apply the brake yourself, the braking effect may not
be sufficient. There is a risk of an accident.
In the event of this malfunction, continue to
depress the brake pedal. The brake system is
still fully functional.
Observe the important safety notes on driving
safety systems (Y page 58).
The Recuperative Brake System converts the
kinetic energy when braking into electrical
energy. The electric motor is used as an alter-
nator during braking. This electrical energy is
then stored in the high-voltage battery.
You can find information about manually adjust- able recuperation under "Steering wheel paddle
shifters" (Y page 115).
If the warning light in the instrument cluster is lit
up, there is a motor malfunction or a brake mal- function.
Observe information regarding indicator and
warning lamps (Y page 192) as well as display
messages (Y page 168). Protection against theft

age battery
Terms of use Observe the following notes:
R information on exceptions and limitations in
warranty documentation and in the related
Maintenance Booklet
R maintenance notes for the high-voltage bat-
tery in the Maintenance Booklet
Method of operation The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode (except D+), kinetic energy is
converted by means of energy recuperation into
electrical energy and stored in the high-voltage
battery.
The high-voltage battery can be charged as fol-
lows:
R through energy recuperation while the vehicle
is in motion
R with the charging cable at a mains socket
while the vehicle is stationary
R with the charging cable at a charging station
while the vehicle is stationary
The high-voltage battery can be charged using a
single-phase charging cable in a voltage range
from 100 V to 240 V.
If the condition of charge drops to less than 13%, the high-voltage battery reserve indicator lamp
lights up in the instrument cluster. Charge the
high-voltage battery as soon as possible.
Below a condition of charge of 5%, the perform-
ance of the vehicle is reduced. The vehicle's
high-voltage electrical system switches off at a
condition of charge of 0%.
Use of the pre-entry climate control function
may mean that the high-voltage battery is not
fully charged. High and low outside temperatures Low outside temperatures
The efficiency of the high-voltage battery is sig-
nificantly reduced at very low outside tempera-
tures. The high-voltage battery is then no longer able to provide the normal electrical power out-
put.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max- imum power output of the high-voltage battery
is reduced automatically.
The E-CELL display indicates the maximum
amount of power available (Y page 152).
Notes on battery care Avoid storing or transporting the vehicle in high
temperatures over a long period (e.g. container
transport).
If you park the vehicle and leave it stationary for
longer periods, connect it to a power supply.
Temperatures below 00F813 ‡ (00F825 †) and over
104 ‡ (40 †), which affect the vehicle for a
period of more than seven days, can cause irre- versible damage.
Discharged battery The vehicle's high-voltage electrical system

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. G
WARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicleis stationary.
Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro- hibit the driver from using a mobile phone while
driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.

Drive sensibly – save energy
Observe the following tips to save energy:
R The tires should always be inflated to the rec-
ommended tire pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not needed.
R Avoid frequent acceleration or braking.
Energy consumption also increases when driv-
ing in low or high outside temperatures, in stop-
start traffic, on short journeys and in hilly ter-
rain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or

Wet roads
If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
R In order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
Servicing the brakes !
The brake fluid level may be too low, if:
R if the red brake warning lamp lights up in
the instrument cluster and
R you hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately.
Consult a qualified specialist workshop to
arrange this.
! A function or performance test should only
be carried out on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult a qualified spe- cialist workshop in advance. You could oth-
erwise damage the drive train or the brake
system. !
As the ESP ®
system operates automatically,
the engine and the ignition must be switched
off (the SmartKey must be in position 0or 1in
the ignition lock) if:
R the electric parking brake is tested on a
brake dynamometer (for a maximum of
ten seconds)
R the vehicle is towed with the front axle
raised.
Braking triggered automatically by ESP ®
may
seriously damage the brake system.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional- ity of your brakes at regular intervals.
You can find a description of Brake Assist (BAS)
on (Y page 59).
Mercedes-Benz recommends that you only have brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which havenot been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for
your vehicle by Mercedes-Benz, or which corre- sponds to an equivalent quality standard. Brakefluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
Checking brake lining thickness You can measure the break pad/lining thick-
ness using a test gage. Color-coding (green or
red) on the test gage allows you to determine
whether the brake pad/lining thickness is still
sufficient. The test gage is in the vehicle docu-
ment wallet in the glove box. 134
