function
(Y page 191).
X Select Standard or Adaptive.
In the Standard setting, no warning vibration
occurs if:
R you operate the turn signal in the corre-
sponding direction. In this event, the warn-
ings are suppressed for a certain period of
time.
R a driving safety system, such as ABS, BAS or
ESP ®
, intervenes or performs a control
action.
When Adaptive is selected, there is also no
warning vibration when: R you accelerate hard, e.g. kickdown.
R brake sharply.
R you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane
marking, the system differentiates between
various conditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, such as a
highway.
R the system detects solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend. Alertness Assistant ATTENTION
ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on freeways and
interstate highways. It is active in the 40 mph
(

60 km/h) to 125 mph (200 km/h) range. If
ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration
on the part of the driver, it suggests taking a
break.
Important safety notes ATTENTION ASSIST is only an aid. The system
may not always detect fatigue or lapses in
concentration until too late, or may not detect
them at all. ATTENTION ASSIST is not a substi-
tute for a well-rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R if the length of the journey is less than
approximately

30 minutes
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving at a speed
below 40 mph (60 km/h) or above 125 mph
(200 km/h)
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset and starts assess-
ing your attention again when you continue
your journey if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break

X Reverse the vehicle, being ready to brake at
all times. Exit the parking space slowly and
do not drive faster than
6 mph (10 km/h).
Otherwise parking assistance is canceled
and Active Parking Assist is stopped.
Active Parking Assist brakes the vehicle to a
standstill when the vehicle approaches the
rear border of the parking space.
Maneuvering may be required in tight parking
spaces. The display shows the Park Assist
Active: Select D Obs. Surroundings
message.
X While the vehicle is stationary, shift the
transmission to position h.
Active Parking Assist immediately steers in
the other direction. The display shows the
Park Assist Active: Accelerate and
Brake Obs. Surroundings message.
i You will achieve the best results by waiting
for the steering procedure to complete
before pulling away.
X Drive forwards and be ready to brake at all
times.
Active Parking Assist brakes the vehicle to a
standstill.
The display shows the Park Assist
Active: Select R Obs. Surroundings
message.
As soon as the parking procedure is complete,
the Park Assist Finished message appears
in the display and a tone sounds. The parking
assistance function of Active Parking Assist is
stopped. The vehicle is parked and kept sta-
tionary without the driver having to depress the brake pedal. The braking effect is canceled
when you depress the accelerator pedal.
Active Parking Assist no longer supports you
with steering interventions and brake applica-
tions. Once active parking assistance has been
stopped, you must steer and brake again your-
self. PARKTRONIC is still available.
Parking tips:
R The way your vehicle is positioned in the
parking space after parking is dependent on
various factors. These include the position
and shape of the vehicles parked in front
and behind it and the conditions of the loca-
tion. It may be the case that Active Parking
Assist guides you too far into a parking
space, or not far enough into it. In some
cases, it may also lead you across or onto
the curb. In this case, cancel the active
parking assistance.
R You can also engage transmission position
h prematurely. The vehicle redirects and
does not drive as far into the parking space.
If you change direction too early, parking
assistance is canceled and Active Parking
Assist is stopped. It is then not possible to
achieve a sensible parking position from the
current position.
Exiting a parking space In order that Active Parking Assist can assist
you when exiting the parking space, the follow-
ing conditions must be fulfilled:
R the border of the parking space must be
high enough at the front and the rear, a
curb, for instance, is not sufficient.
R the border of the parking space must not be
too wide. Your vehicle can be maneuvered
into a position at a maximum of 45° to the
starting position in the parking space.
R a maneuvering distance of at least

3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically when exiting
from the parking space. You are responsible
for braking in good time. 162

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.
Read the information on qualified specialist
workshops (Y page
32).Important safety notes
G
WARNING
If you operate information systems and com-
munication equipment integrated in the
vehicle when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
Only operate this equipment when the traffic
situation permits. If you are not sure that
this is possible, park the vehicle paying
attention to traffic conditions and operate
the equipment when the vehicle is station-
ary. G
WARNING
If you are driving and reach through the
steering wheel to operate the adjustment
knob, you could lose control of the vehicle.
There is a risk of an accident and injury.
Only operate the adjustment knobs when
the vehicle is stationary. Do not reach
through the steering wheel when driving.
You must observe the legal requirements for
the country in which you are currently driving
when operating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer display only shows
messages and warnings from certain systems.
You should therefore make sure your vehicle is
operating safely at all times. If the operating
safety of your vehicle is impaired, stop the
vehicle as soon as possible, paying attention
to road and traffic conditions. Then consult a
qualified specialist workshop.
The accuracy of the speedometer and odome-
ter displays is legally prescribed. Determining
the speed is dependent on the wheel size or
the rolling circumference of the wheels. If you
change the wheel size on your vehicle, make
sure it is assigned to the correct wheel size
category ( Y page
278). If you change wheel
size category without recoding the control
unit, the speedometer indication will be inac-
curate. Driving safety and driving systems may
be impaired or detect a malfunction and shut
down.
