emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.
Distance warning function (vehicles
with DISTRONIC)
This function warns you from a speed of
approximately 20 mph (30 km/h), if:
R for a period of several seconds, the
distance to the vehicle in front is too short
for the speed at which you are traveling.
The · distance warning lamp in the
instrument cluster will light up.
R you are approaching the vehicle in front
rapidly. An intermittent warning tone will
then sound and the · distance warning
lamp in the instrument cluster will light up.
You must apply the brakes yourself in order
to maintain the appropriate distance to the
vehicle in front and prevent a collision.
GWarning!
If the distance warning lamp · in the
instrument cluster comes on while driving
and/or an intermittent warning sounds,
immediate attention on the part of the driver
is required. As required by the traffic
situation, apply the brakes and navigate
around a possible obstacle. However, do not
drive by relying on the distance warning
function, as this will result in an emergency
braking application. This will not always
enable you to avoid a collision, especially
when traveling on varying road surface
conditions and with varying driver reaction.
Complex driving situations are not always
fully recognized by the distance warning
function. This could result in wrong or missing
distance warnings.
XTo activate/deactivate: activate or
deactivate the distance warning function in
the on-board computer ( Y page 219).
After activation, the Ä symbol is
displayed in the lower multifunction
display.

SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned by these
parts.
GWarning!
Do not carry heavy or hard objects in the
passenger compartment or cargo
compartment unless they are firmly secured
in place.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident

Important information about using
KEYLESS-GO
R You can use the KEYLESS-GO key as a
conventional SmartKey.
R You can combine KEYLESS-GO functions
with those of a conventional SmartKey, e.g.
you can open the vehicle with KEYLESS-GO
and close it with the & button.
R Always carry your KEYLESS-GO key on your
person.
R Never store the KEYLESS-GO key together
with:
- electronic devices, such as a mobile
phone or other SmartKey
- metal objects, such as coins or metal foil
Doing so may impair the function of
KEYLESS-GO.
R To open or close the vehicle, the KEYLESS-
GO key should not be more than 3 ft (1 m)
from the door or tailgate.
R If the vehicle is parked for more than
72 hours, the KEYLESS-GO function is
deactivated. Pull an outer door handle and
switch on the ignition to reactivate the
KEYLESS-GO function.
R If the KEYLESS-GO key is removed from the
vehicle, the system may not be able to
recognize the SmartKey anymore. The
vehicle can then no longer be locked or
started with KEYLESS-GO.
R If the KEYLESS-GO key has been removed
from the vehicle, e.g. when another vehicle
occupant with a KEYLESS-GO key leaves
the vehicle:
- when the Start/Stop button is pressed,
or when trying to lock the vehicle using
the locking button on the outside door
handle, the Key Not Detected message
appears in the multifunction display.
- when the engine is running, the red Key
Not Detected message appears in the
multifunction display as you pull away.
Look for the KEYLESS-GO key and place
it somewhere else in the vehicle. Place
the KEYLESS-GO key on the front-
passenger seat, for example, or in your
shirt pocket.
R If you have switched on the engine with the
Start/Stop button, you can switch it off
again by:
- pressing the Start/Stop button
- inserting the KEYLESS-GO key into the
ignition lock while the vehicle is at a
standstill and the automatic
transmission is in park position P.
R You may inadvertently unlock the vehicle if
the KEYLESS-GO key is less than 3 ft (1 m)
from the vehicle and:
- an exterior door handle is hit by a jet of
water, or
- you clean an exterior door handle
R Please note that any vehicle occupant can
start the engine when there is a KEYLESS-
GO key in the vehicle.
Scenario 1: There is a KEYLESS-GO key in
the vehicle and a second one outside the
vehicle. If you leave the KEYLESS-GO key
in the vehicle when you leave and lock the
vehicle, no message appears in the
multifunction display.
Scenario 2: There is a KEYLESS-GO key in
the vehicle, but none outside the vehicle. If
you get out of the vehicle and attempt to
lock it, the Key Detected In Vehicle
message appears in the multifunction
display. The vehicle is not then locked.
When starting the engine and whilst driving,
KEYLESS-GO also checks whether a valid
SmartKey is in the vehicle by periodically
establishing radio contact.74SmartKeyOpening and closing
