system manufacturer's installation instruc-
tions.
XPull the front seat belt smoothly out of the
seat-belt extender and the rear seat belt out
of the belt sash guide.
XEngage seat belt tongue in belt buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the inertia
reel retract it again.
While the seat belt is retracting, you should
hear a ratcheting sound. The special seat belt
retractor is enabled.
XPush the child restraint system down so that
the seat belt is tight and does not loosen.
Removing the child restraint system and deac-
tivating the special seat belt retractor:
XMake sure you observe the child restraint
system manufacturer's installation instruc-
tions.
XPress the release button of the seat belt
buckle, hold the seat belt tongue and route it
to the seat belt extender in front or the belt
sash guide in the rear compartment.
The special seat belt retractor is deactivated.
Child restraint system
The use of seat belts and child restraint systems
is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
You can obtain further information about the
correct child restraint system from any author-
ized Mercedes-Benz Center.
GWARNING
If the child restraint system is installed incor-
rectly on a suitable seat, it cannot protect as
intended. The child cannot then be restrained
in the event of an accident, heavy braking or
sudden changes of direction. There is an
increased risk of injury, possibly even fatal.
Make sure that you observe the child restraint
system manufacturer's installation instruc-
tions and the notes on use. Please ensure,
that the base of the child restraint system is
always resting completely on the seat cush-
ion. Never place objects, e.g. cushions, under or behind the child restraint system. Only use
child restraint systems with the original cover
designed for them. Only replace damaged
covers with genuine covers.
GWARNING
If the child restraint system is installed incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik-
ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always install child restraint systems prop-
erly, even if they are not being used. Make
sure that you observe the child restraint sys-
tem manufacturer's installation instructions.
You will find further information on stowing
objects, luggage or loads under "Loading guide-
lines" (
Ypage 266).
GWARNING
Child restraint systems or their securing sys-
tems which have been damaged or subjected
to a load in an accident can no longer protect
as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There is an increased risk of injury, possibly even
fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the secur-
ing systems on the child restraint system
checked at a qualified specialist workshop,
before you install a child restraint system
again.
The securing systems of child restraint systems
are:
Rthe seat belt system
Rthe LATCH-type (ISOFIX) securing rings
Rthe Top Tether anchorages

Safety

Always pay careful attention to the traffic sit-uation and be ready to brake.
Always adapt your speed to suit the prevailing
road and traffic conditions.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause Brake Assist to intervene.
If adaptive Brake Assist is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full brake
boosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-
tion (Ypage 63).
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/4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion (Ypage 63).
ETS traction control is part of ESP
®. On vehicles
with 4MATIC, 4ETS 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
iObserve the "Important safety notes" sec-
tion (Ypage 63).
GWARNING
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 the vehicle with the rear axle
raised, observe the notes on ESP
®
(Ypage 311).
If the å ESP®OFF warning lamp lights up
continuously, ESP®is deactivated.
If the ÷ ESP®warning lamp lights up contin-
uously, ESP®is not available due to a malfunc-
tion.
Observe the information on warning lamps
(
Ypage 247) and display messages which may
be shown in the instrument cluster
(
Ypage 217).
Only use wheels with the recommended tire
sizes. Only then will ESP
®function properly.
Characteristics of ESP®
General information
If the ÷ ESP®warning lamp goes out before
beginning the journey, ESP®is automatically
active.
If ESP
®intervenes, the ÷ESP®warning lamp
flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
necessary when pulling away.
XAdapt your driving style to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle stops
moving. The engine starts automatically when
the driver wants to pull away again. ESP
®
remains in its previously selected status, e.g. if
ESP®was deactivated before the engine was
automatically switched off.

GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
!Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its driv-
etrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
Rthe electric parking brake must be applied.
Rthe transmission must be in position jand
the SmartKey must be removed from the igni-
tion lock.
Rthe front wheels must be turned towards the
curb on steep uphill or downhill gradients.
Rthe empty vehicle must be secured at the
front axle with a wheel chock or similar, for
example, on uphill or downhill gradients.
Ron uphill or downhill gradients the laden vehi- cle must also be secured at the rear axle, for
example with a wheel chock or similar object.
Switching off the engine
Important safety notes
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
Vehicles with automatic transmission
XApply the electric parking brake.
XShift the transmission to position j.
XWith the SmartKey:turn the SmartKey to
position uin the ignition lock and remove it.
The immobilizer is activated.
XWith the Start/Stop button: press the
Start/Stop button (Ypage 127).
The engine stops and all the indicator lamps in
the instrument cluster go out.
When the driver's door is closed, this corre-
sponds to key position 1. When the driver's
door is open, this corresponds to key position
u, "Key removed".
If you switch the engine off with the transmis-
sion in position korh the automatic trans-
mission shifts to iautomatically.
With the SmartKey: if you then open the driv-
er's door or the front-passenger door or remove the SmartKey from the ignition, the automatic
transmission shifts to jautomatically.
With the Start/Stop button: if you then open
the driver's door or the front-passenger door,
the automatic transmission shifts to jauto-
matically.
If you want the automatic transmission to
remain in neutral i, for example, when having
the vehicle cleaned in an automatic car wash
with a towing system:
XVehicles with KEYLESS-GO or KEYLESS-
GO start function: remove the Start/Stop
button from the ignition lock.
XInsert the SmartKey into the ignition lock.
XAll vehicles: switch the ignition on.
XDepress the brake pedal and keep it
depressed.
XEngage neutral i.
XRelease the brake pedal.
XRelease the electric parking brake.
XSwitch off the ignition and leave the SmartKey
in the ignition lock.

equipment.
Important safety notes
GWARNING
Distance Pilot DISTRONIC does not react to:
Rpeople or animals
Rstationary objects on the road, e.g. stopped
or parked vehicles
Roncoming vehicles and crossing traffic
As a result, Distance Pilot DISTRONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
GWARNING
Distance Pilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may:
Rgive an unnecessary warning and then
brake the vehicle
Rneither give a warning nor intervene
Raccelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you.
GWARNING
Distance Pilot DISTRONIC brakes your vehicle with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you
with a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and try to take evasive action.
!When Distance Pilot DISTRONIC or the
HOLD function are activated, the vehicle
brakes automatically in certain situations. To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
Rwhen towing the vehicle
Rin the car wash
Distance Pilot DISTRONIC can neither reduce
the risk of an accident if you fail to adapt your
driving style nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tance Pilot DISTRONIC is only an aid. You are
responsible for maintaining a safe distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
Do not use Distance Pilot DISTRONIC:
Rin road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rain or
snow
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for exam-
ple in parking garages
If Distance Pilot DISTRONIC no longer detects a
vehicle in front, it may unexpectedly accelerate
to the speed stored.
This speed may:
Rbe too high if you are driving in a turning lane
or an exit lane
Rbe so high in the right lane that you pass vehi- cles driving on the left (in countries where
they drive on the right)
Rbe so high in the left lane that you pass vehi-
cles driving on the right (in countries where
they drive on the left)
If there is a change of drivers, advise the new
driver of the speed stored.
