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.
Protection against theft
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.

The SmartKey centrally locks/unlocks:
Rthe doors
Rthe trunk lid
Rthe glove box
Rthe stowage compartment under the arm-
rest
Rthe stowage compartment in the rear com-
partment
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 235).
When it is dark, the surround lighting also
comes on if it is activated in the on-board
computer (
Ypage 234).
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). A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart-
Key is in the vehicle. This occurs, for example:
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
closing feature (
Ypage 99).
XTo unlock the trunk lid: pull the handle on
the trunk lid.
The vehicle only unlocks the trunk lid.
Deactivating and activating
If you do not intend to use a SmartKey for an
extended 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.
