Starting the engine
Important safety notes
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
!Do not depress the accelerator when start-
ing the engine.
XBefore starting the engine, make sure that:
Rall the doors are closed.
Rall the vehicle occupants are wearing their
seat belts correctly.
Rthe parking brake is applied.
iIf you depress the brake pedal before start-
ing the engine, the pedal travel may be shorter
and pedal resistance higher.
If you depress the brake pedal again after
starting the engine, pedal travel and resist-
ance will be back to normal again.
Automatic transmission
XShift the transmission to position P
(Ypage 127).
The transmission position indicator in the dis-
play shows P.
You can also start the engine in neutral N.
Starting the engine
XTurn the key to position3in the ignition lock
(Ypage 121) and release it as soon as the
engine is running.
Driving off
Automatic transmission
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
!Only shift into reverse gear Rwhen the vehi-
cle is stationary. Otherwise, you could dam-
age the transmission.
XDepress the brake pedal and keep it
depressed.
The parking lock is released.
XShift the transmission to position Dor R.
On vehicles with a reverse warning feature, a
warning signal sounds when reverse gear Ris
engaged to alert other road users
(
Ypage 123).
XRelease the parking brake (Ypage 134).
The F (only USA) or J(only Canada)
indicator lamp in the instrument cluster goes
out.
XRelease the brake pedal.
Hill start assist automatically maintains the
brake pressure for about another two sec-
onds after the brake pedal is released. This
makes it possible to pull away without the
vehicle immediately rolling back
(
Ypage 123).
XCarefully depress the accelerator pedal.
It is only possible to shift the transmission from
position Pto the desired position if you depress
the brake p
edal. Only then is the parking lock
released. If the brake pedal is not depressed, the
DIRECT SELECT lever can still be moved but the
parking lock remains engaged.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 74).

Driving and parking

In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt on the sensors or anything else covering
the sensors
Rsnow or heavy rain
Rinterference from other radar sources
Rstrong radar reflections, for example, in park-
ing garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause Adaptive Brake Assist to inter-
vene.
If you fail to adapt your driving style, Adaptive
Brake Assist can neither reduce the risk of acci-
dent nor override the laws of physics. Adaptive
Brake Assist cannot take into account road,
weather or traffic conditions. Adaptive Brake
Assist is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, braking in good time and for staying in
your lane.
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow
speeds where there is no visible damage to the
front of the vehicle.
If you change wheel size, make sure they corre- spond to the correct wheel size category
(
Ypage 277). If the category is changed without
recoding the control units in the vehicle, the
functioning of Adaptive Brake Assist may be
impaired. COLLISION PREVENTION ASSIST may
then detect a malfunction and switch itself off.
If Adaptive Brake Assist is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full brake
boosting effect and BAS.
Operation
With the help of the radar sensor system, Adap-
tive Brake Assist can detect obstacles that have been in the path of your vehicle for an extended
period of time. Ada

ptive Brake Assist does not
react to stationary obstacles. If Adaptive Brake
Assist detects a risk of collision with a vehicle
traveling in front or with a stationary obstacle,
the system calculates the braking force neces-
sary to avoid this collision. If you apply the
brakes forcefully, Adaptive Brake Assist will
automatically increase the braking force to a
level suitable for the traffic conditions.
XBrake until the distance to the obstacle
increases and the risk of a collision passes.
ABS prevents the wheels from locking.
The brakes function as usual again if:
Ryou release the brake pedal
Rthere is no longer any danger of a collision
Rno obstacle is detected in front of your vehicle
Braking assistance is then ended.
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sensors
in the bumper. It supports you from speeds of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your atten-
tion to vehicles detected in the monitored area.
If you then switch on the corresponding turn
signal to change lane, you will also receive an
optical and audible collision warning.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
146Driving systems
Driving and parking

Warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
approximately 20 mph (30 km/h), warning
lamp:lights up red in the exterior mirror on
the corresponding side. Warning lamp :
always lights up when a vehicle enters the blind
spot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
only occurs if the difference in speed is less than
7 mph (11 km/h).
If you select reverse gear, Blind Spot Assist is
inactive.
The intensity of warning lamps :depends on
the brightness of the ambient light and is con-
trolled automatically.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds once. The warning lamp in the corre-
sponding exterior mirror flashes. If the turn sig-
nal remains on, detected vehicles are indicated
by the flashing of the warning lamp in the exte-
rior mirror. There are no further warning tones.
Activating Blind Spot Assist
XMake sure that Blind Spot Assist is activated
in the on-board computer (Ypage 185).
XTurn the key to position 2in the ignition lock.
The warning lamps in the exterior mirrors light
up for approximately 1.5 seconds.
Status indicators in the status overview submenu
If Blind Spot Assist is activated, the display
shows symbol :in the StatusOverviewsub-
menu of the on-board computer (Ypage 184). If
you are driving faster than 20 mph (30 km/h),
the symbol also shows radar waves ;between
the two vehicles. Blind Spot Assist is then ready
for use.
Towing a trailer
If you attach a trailer, make sure that you have
correctly established the electrical connection.
This can be accomplished by checking the trailer
lighting. Blind Spot Assist is then deactivated
and the Blind Spot Assist Currently
Unavail. See Operator's Manualmessage
appears in the display.
Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of camera :which is
mounted at the top of the windshield. Lane
Keeping Assist detects lane markings on the
road and can warn you before you leave your
lane unintentionally.
This function is available in the range between
40 mph (60 km/h) and 125 mph (200 km/h).
A warning may be given if a front wheel touches a lane marking. It will warn you by means of

are shown as solid lines;.
Setting the sensitivity of Lane Keeping
Assist
XIn theAssist.menu on the on-board com-
puter, select the Lane Keeping Assist:
function (Ypage 185).
XSelectStandardorAdaptive.
In the setting Standard
, no warning vibration
occurs if:
Ryou operate the turn signal in the correspond-
ing direction. In this event, the warnings are
suppressed for a certain period of time.
Ra 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:
Ryou accelerate hard, e.g. kickdown.
Rbrake sharply.
Ryou steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
Ryou 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 mark-
ing, the system differentiates between various
conditions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, such as a high-
way.
Rthe system detects solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou 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 con-
centration until too late, or may not detect them
at all. ATTENTION ASSIST is not a substitute for
a well-rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all:
Rif the length of the journey is less than approx-
imately 30 minutes
Rif the road condition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving at a speed
below 40 mph (60 km/h) or above 125 mph
(200 km/h)
Rif the time has been set incorrectly
Rin active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset and starts assessing
your attention again when you continue your
journey if:
Ryou switch off the engine
Ryou take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
Displaying the attention level
For vehicles with steering wheel buttons you can
have the current ATTENTION ASSIST (Attention
Level) assessment displayed.

Driving and parking

Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer
:Detected parking space on the left
;Parking symbol
=Detected parking space on the right
If the driver's seat belt is fastened and all doors
are closed, Active Parking Assist is activated
automatically when driving forwards. The sys-
tem is operational at speeds of up to approx-
imately 22 mph (35 km/h). While in operation,
the system independently locates and meas-
ures parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel and are at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel and
at least 40 in (1.0 m) longer than your vehicle
Rthat are at right angles to the direction of
travel and at least 40 in (1.0 m) widerthan
your vehicle
iNote that Active Parking Assist cannot
measure the length of a parking space if it is at right angles to the direction of travel. You will
need to judge whether your vehicle will fit in
the parking space.
When the vehicle is driving at speeds of up to
approximately 20 mph (30 km/h), parking sym-
bol ;is shown as a status display in the header.
The syste m d
etects and differentiates between
parking spaces which are parallel or at right
angles to the direction of travel. When a parking
space is detected, an arrow appears next to
parking symbol ;to indicate which side the
parking space is on. The parking space is dis-
played while you are driving past it and until you
are approximately 50 ft (15 m) away from it.
Active Parking Assist displays parking spaces on
the passenger side as standard. The parking
spaces on the driver's side are only displayed if
you operate the turn signal on the driver's side.
When parking on the driver's side, you must
operate the turn signal until you have started
active parking assistance by pressing the a
button on the steering wheel.
Parking
GWARNING
If you leave the driver's seat when the vehicle is only being braked by Active Parking Assist,
the vehicle could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
Rthe battery is disconnected.
Rthe vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the driver's seat, always secure the vehicle against rolling away.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically during the park- ing process. You are responsible for braking in
good time.

ary 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:
RThe way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditions of the location. 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.
RYou can also select transmission position D
prematurely. The vehicle redirects and does
not drive as far into the parking space. If you
change direction too early, parking assis-
tance 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:
Rthe border of the parking space must be high
enough at the front and the rear. A curb is too
small, for example.
Rthe 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.
Ra 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.
XStart the engine.
XSwitch on the turn signal in the direction in
which you are pulling away.
