ABS (Anti-lock Braking System)
Gene ral inform ation
ABSregulates brak epressur ein suc h away
that th ewheels do no tloc kwhen you brake.
This allows you to continu esteering th evehi-
cle when braking .
The ! ABSwarning lamp in th einstrumen t
cluste rlights up when th eignition is switched
on .It goes out when th eengin eis running.
AB Sworks from aspee dof about 5mph
(8 km/h), regardless of road-surface condi-
tions. AB Sworks on slippery surfaces, eve n
when you only brak egently.

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 prevail-
ing 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 automati-
cally when the driver wants to pull away again.
ESP
®remains in its previously selected sta-
tus. Example: if ESP®was deactivated before
the engine was switched off, ESP®remains
deactivated when the engine is switched on
again.

It may be best to deactivate ESP®in the fol-
lowing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
iActivate ESP®as soon as the situations
described above no longer apply. ESP®will
otherwise not be able to stabilize the vehi-
cle if the vehicle starts to skid or a wheel
starts to spin.
!Avoid spinning the driven wheels for an
extended period with ESP®deactivated.
You could otherwise damage the drivetrain.

XBrake immediately to defuse the situation.
or
XTake evasive action provided it is safe to do
so.
PRE-SAFE
®Brake can also brake the vehicle
automatically under the following conditions:
Rthe driver and front-passenger have their
seat belts fastened
and
Rthe vehicle speed is between approx-
imately 4 mph (7 km/h) and 124 mph
(200 km/ h)
At speeds of up to approximately 40 mph
(70 km/h) PRE-SAFE
®Brake can also detect
stationary objects. Examples of stationary
objects are stopped or parked vehicles.
iIf there is an increased risk of collision,
preventive passenger protection measures
(PRE-SAFE
®) are activated.
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking,
up to the point of full brake application. Auto-
matic emergency braking is not performed
until immediately prior to an imminent acci-
dent.
You can prevent the intervention of the PRE-
SAFE
®Brake at any time by:
Rdepressing the accelerator pedal further.
Ractivating kickdown.
Rreleasing the brake pedal.
The braking action of PRE-SAFE
®Brake is
ended automatically if:
Ryou maneuver to avoid the obstacle.
Rthere is no longer any danger of a collision.
Rthere is no longer an obstacle detected in
front of your vehicle.
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 partic-
ular if:
Rboth right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
Rthe vehicle starts to skid.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 71).
No steering support is provided from STEER
CONTROL, if:
RESP®is malfunctioning.
Rthe lighting is faulty.
Power steering will, however, continue to
function.

Immobilizer
XTo activate with the SmartKey: remove
the SmartKey from the ignition lock.
XTo activate with KEYLESS-GO: switch the
ignition off and open the driver's door.
XTo deactivate: switch on the ignition.
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. The
engine can be started by anyone with a valid
SmartKey that is left inside the vehicle.
iThe immobilizer is always deactivated
when you start the engine.
In the event that the engine cannot be star-
ted (yet the vehicle's battery is charged),

SmartKey battery
Important safety notes
GWARNING
Batteries contain toxic and corrosive substan- ces. If batteries are swallowed, it can result in
severe health problems. There is a risk of fatalinjury.
Keep batteries out of the reach of children. If
a battery is swallowed, seek medical attention immediately.
Mercedes-Benz recommends that you have
the batteries replaced at a qualified specialist
workshop.
The SmartKey batteries contain perchlorate
material, which may require special handling
and regard for the environment. National
guidelines must be observed during disposal.
In California, see www.dtsc.ca.gov/Hazard-
ousWaste/Perchlorate/index.cfm.
Checking the battery
XPress the &or% button.
The battery is working properly if battery

XSwitch off non-essential consumers, e.g. seat heating or interior
lighting, and try to start the engine again.
If this does not work:
XCheck the starter battery and charge it if necessary
(
Ypage 557).
or
XJump-start the vehicle (Ypage 559).
or
XConsult a qualified specialist workshop.

Doors
Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
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 or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
Unlocking and opening doors from
the inside
!
The side windows will not open/close if
the battery is discharged or if the side win-
dows have iced up. It will then not be pos-
sible to close the door. Do not attempt to
force the door closed. You could otherwise
damage the door or the side window.
You can open a door from inside the vehicle
even if it has been locked.
If the vehicle was previously locked with the
SmartKey or with KEYLESS-GO, opening the
vehicle from the inside will activate the anti-
theft alarm system. Switch off the alarm
(
Ypage 80).

Trunk
Important safety notes
GWARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
!The trunk lid swings upwards when
opened. Therefore, make sure that there is
sufficient clearance above the trunk lid.
!Only close the trunk once the roof is low-
ered completely. Otherwise, you could
damage the roof. If you close the trunk lid before the roof is
lowered completely, the loading aid switch
lights up and a warning tone sounds.
iOpening dimensions of the trunk lid
(
Ypage 608).
iWith the roof open, you can use the load-
ing aid (
Ypage 516) to raise the folded roof
in the trunk to make loading easier. For this
purpose, you can also open the trunk par-
tition.
The trunk partition must be closed again
after loading. It will otherwise not be pos-
sible to close the roof.
You can unlock the trunk lid if the vehicle is
stationary and the roof is completely open or
closed.
Do not leave the SmartKey in the trunk. You
could otherwise lock yourself out.
The trunk lid can be:
Ropened/closed from outside
Ropened and closed automatically from out-
side (vehicles with trunk lid remote closing
feature)
Ropened and closed automatically from
inside (vehicles with trunk lid remote clos-
ing feature)
Ropened, closed or stopped during opera-
tion without the use of your hands (vehicles with KEYLESS-GO and HANDS-FREE
ACCESS)
Rlocked separately

Trunk lid reversing feature
The trunk lid is equipped with an automatic
reversing feature. It reacts if a solid object
obstructs or restricts the trunk lid during the
closing procedure. The trunk lid opens again
automatically. The automatic reversing func-
tion is only an aid and is not a substitute for
your attentiveness to the trunk lid while it is
closing.
