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 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.
Deactivating/activating ESP®
Important safety notes
You can select between the following states
of ESP
®:
RESP®is activated.

GWARNING
If you deactivate ESP
®, ESP®no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP
®in the situations descri-
bed in the following.
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.
Deactivating/activating ESP

start to spin, the ÷ESP®warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP
®will not stabilize the vehicle.
If you deactivate ESP
®:
RESP®no longer improves driving stability.
Rengine torque is no longer limited and the
drive wheels are able to spin.
74Driving safety systems
Safety

Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Function
XTo activate/deactivate: activate or deac-
tivate PRE-SAFE®Brake in the on-board
computer (
Ypage 282).
If the PRE-SAFE®Brake is not activated, the
æ symbol appears in the multifunction
display.
If you have activated DSR (
Ypage 257), PRE-
SAFE®Brake is deactivated.
Starting at a speed of around 4 mph (7 km/h),
this function warns you if you rapidly
approach a vehicle in front. An intermittent
warning tone will then sound and the ·
distance warning lamp will light up in the
instrument cluster.
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)
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,
u

p 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 68).
No steering support is provided by STEER
CONTROL, if:
RESP®is malfunctioning.
Rthe lighting is faulty.

If you do not open the vehicle within
approximately 40 seconds of unlocking:
Rthe vehicle is locked again.
Rprotection against theft is reactivated.
XTo lock centrally:press button:.
The SmartKey centrally locks and unlocks the following components:
Rthe doors
Rthe tailgate
Rthe fuel filler flap
The turn signals flash once when unlocking
and three times when locking.
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated and deactivated using
the on-board computer (
Ypage 285).
You will receive visual and acoustic locking
confirmation if all components were able to
be locked.
When it is dark, the surround lighting also
comes on if it is activated in the on-board
computer (
Ypage 284).
KEYLESS-GO
General notes
Bear in mind that the engine can be started by
any of the vehicle occupants if there is a KEY-
LESS-GO key in the vehicle.
Locking/unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry
the SmartKey with you. You can combine the functions of KEYLESS-GO with those of a con-
ventional SmartKey. Unlock the vehicle by
using KEYLESS-GO, for instance, and lock it
using the &button on the SmartKey.
When locking or unlocking with KEYLESS-GO,
the distance between the SmartKey and the
corresponding door handle must not be
greater than 3 ft (1 m). KEYLESS-GO checks whether a valid Smart-
Key is in the vehicle by periodically establish-
ing a radio connection between the vehicle
and the SmartKey. This happens:
Rwhen the external door handles are
touched
Rwhen starting the engine
Rwhile the vehicle is in motion
XTo unlock the vehicle:
touch the inner
surface of the door handle.
XTo lock the vehicle: touch sensor sur-
face :.
XConvenience closing feature: touch
recessed sensor surface ;for an exten-
ded period.
Further information on the convenience clos-
ing feature (
Ypage 99).
If you pull on the handle of the tailgate, only
the cargo compartment of the vehicle is
unlocked.
Deactivating and activating
If you do not intend to use a key for an exten-
ded period of time, you can deactivate the
KEYLESS-GO function of the SmartKey. The
SmartKey will then use very little power,
thereby conserving battery power. For the
purposes of activation/deactivation, the
vehicle must not be nearby.
