Select one of the following:
Eco - Pilot Assist will focus on providing
optimal fuel economy, which will increase the
time interval to the vehicle ahead.
Comfort - Pilot Assist will focus on following
the set time interval to the vehicle ahead as
smoothly as possible.
Dynamic - Pilot Assist will focus on follow-
ing the set time interval to the vehicle ahead
more exactly, which could mean faster accel-
eration and heavier braking.

Starting passing assistance with
Pilot Assist
Several conditions must be met for passing
assistance to be possible.
In order to activate passing assistance:
your vehicle must be following a vehicle
ahead (target vehicle)
your vehicle's current speed must be
at least 70 km/h (43 mph)
the set speed for Pilot Assist must be high
enough to safely pass another vehicle.
Starting parking assistanceTo start passing assistance:
–
Turn on the left turn signal.
>

Passing assistance will start.

Passing assistance with Pilot Assist (p. 326) Passing assistance with Pilot Assist
limitations
Passing assistance functionality may be reduced
in certain situations.
WARNING The driver should be aware that if conditions
suddenly change when using Parking Assis-
tance, the function may implement an unde-
sired acceleration in certain conditions.
Some situations should be avoided, e.g. if:

the vehicle is approaching an exit in the
same direction as passing would normally
occur
the vehicle ahead slows before your vehi-
cle has had time to switch to the passing
lane
traffic in the passing lane slows down
a vehicle for right-hand traffic is driven in
a country with left-hand traffic (or vice
versa).
Situations of this type can be avoided by tempo-
rarily putting Pilot Assist in standby mode.

Passing assistance with Pilot Assist (p. 326) Switching target vehicles with Pilot
Assist
At certain speeds, models with automatic trans-
missions and

Pilot Assist can switch target vehi-
cles.
Switching target vehicles If the target vehicle ahead turns suddenly, there may be
stationary traffic ahead.
When Pilot Assist is actively following another
vehicle at speeds under 30 km/h (20 mph) and
switches targets from a moving vehicle to a sta-
tionary vehicle,

Pilot Assist will brake for the sta-
tionary vehicle.

||DRIVER SUPPORT

WARNING
When Pilot Assist follows another vehicle at
speeds over approx. 30 km/h (20 mph) and
changes target vehicle – from a moving vehi-
cle to a stationary one – Pilot Assist will
ignore the stationary vehicle and instead
accelerate to the stored speed.
The driver must then intervene and apply
the brakes.
Automatic standby mode when switching
targets
Pilot Assist disengages and goes into standby
mode if:
your vehicle's speed goes below 5 km/h
(3 mph) and Pilot Assist cannot determine if
the target object is a stationary vehicle or
another object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
Pilot Assist no longer has a vehicle to follow.

Pilot Assist (p. 316) Auto-hold braking with Pilot Assist
Pilot Assist has a special braking function in
slow traffic and at a standstill.
Braking function in slow traffic and at a
standstill
In slow-moving, stop-and-go traffic or when stop-
ped at a traffic light, driving will resume automati-
cally if the vehicle is stopped for less than
approx. 3 seconds. If it takes more than 3 sec-
onds for the vehicle ahead to begin moving again,
Pilot Assist will go into standby mode and the
Auto-hold brake function will activate.
– Pilot Assist can be reactivated by:
Pressing the button on the steering
wheel keypad.
Pressing the accelerator pedal.
>

Pilot Assist will resume following the vehi-
cle ahead if it begins to move within
approx. 6 seconds.
NOTE Pilot Assist can keep the vehicle stationary
for no more than 5 minutes – after that time
the parking brake is applied and the function
is deactivated.
The parking brake must be released before
Pilot Assist can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated
when the vehicle is at a standstill and Pilot Assist
will go into standby mode. This means that the
brakes will be released and the vehicle could
begin to roll. The driver must actively apply the
brakes to keep the vehicle stationary.
This can occur if:
the driver depresses the brake pedal
the parking brake is applied
the gear selector is moved to the P, N or R
positions
the driver puts Pilot Assist in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will be
applied to keep the vehicle at a standstill.
This occurs if Pilot Assist is keeping the vehicle
stationary using the brakes and:
the driver opens the door or unbuckles
his/her seat belt
Pilot Assist has kept the vehicle at a stand-
still for more than approx. 5 minutes
the brakes overheat
the driver switches off the engine manually.

Recommended maintenance for the
camera/radar sensor
In order for the camera/radar sensor to function
properly, the area of the windshield in front of
the unit must be kept free of dirt, ice, snow, etc.
and should be washed regularly with water and
car washing detergent.
NOTE Dirt, ice and snow covering the camera and
radar unit reduce their function and can make
measurement impossible.
It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.

Camera (p. 337) City Safety™
City Safety can alert the driver with light, sound
and pulsations in the brake pedal to help the
driver detect pedestrians, cyclists, large animals
and vehicles that appear suddenly – the vehicle
will then attempt to automatically brake if the
driver does not act within a reasonable amount
of time. Location of the camera and radar sensor
70
.
City Safety can help prevent a collision or lower
the vehicle's speed at the point of impact.
City Safety is an aid intended to assist the driver
if a collision with a pedestrian, large animal,
cyclist or vehicle is imminent.
City Safety can help the driver avoid a collision
when e.g. driving in stop-and-go traffic, when changes in the traffic ahead and driver distraction
could lead to an incident.
The function assists the driver by automatically
applying the brakes if there is an imminent risk of
a collision and the driver does not react in time by
braking and/or steering away.
City Safety activates a brief, forceful braking in an
attempt to stop your vehicle immediately behind
the vehicle or object ahead.
City Safety is activated in situations in which the
driver should have applied the brakes much ear-
lier, which means that the system will not be able
to assist the driver in all situations.
City Safety is designed to be activated as late as
possible to help avoid unnecessary intervention.
Normally, the occupants of the vehicle will not be
aware of City Safety except when the system
intervenes when a collision is imminent.

2 - Brake assistance
If the risk of a collision increases after the colli-
sion warning, brake support will be activated.
If the system determines that the pressure the
driver is exerting on the brake pedal is insufficient
to prevent the collision, brake support will
increase pressure.
3 - Auto-brake
The automatic braking function is activated at the
last moment.
If the driver has not taken evasive action by this
stage and a collision is imminent, the automatic
braking function will be triggered. This occurs
whether or not the driver is pressing the brake
pedal. Full braking force will be applied to reduce
the speed at impact or reduced braking effect will
be applied if this is sufficient to avoid the colli-
sion.
The seat belt tensioners may be activated along
with the automatic braking function. See "Seat
belt tensioners" for more information.
In certain situations, auto-braking may begin with
a limited braking force before applying full brak-
ing force.
If City Safety has prevented a collision, the vehi-
cle will be kept at a standstill until the driver
takes action. If the vehicle has slowed to avoid
colliding with a slower-moving vehicle ahead, your
speed will be reduced to that vehicle's speed.
Auto-braking can always be cancelled if the
driver presses hard on the accelerator pedal.
NOTE When City Safety activates the brakes, the
brake lights come on.
When City Safety applies the brakes, a text mes-
sage will appear in the instrument panel to notify
the driver that the function is/was activated.
WARNING
City Safety may not be used to change how
the driver operates the vehicle. The driver
must not only rely on City Safety to brake the
vehicle.

City Safety™ (p. 341) Setting a warning distance for City
Safety
City Safety is always active, but the function's
warning distance can be adjusted.
NOTE The City Safety function cannot be deacti-
vated. It is activated automatically each time
the engine/electric motor is started.
The alert distance determines the sensitivity of
the system and regulates the distance at which
the light, sound and brake pulsations will be acti-
vated.
To select warning distance:
1.

Select Settings My Car IntelliSafe
in
the center display's Top view.
2. Under City Safety Warning, tap Late,
Normal or Early to set the desired warning distance.
If the driver feels that the Early setting is giving
too many warnings or finds them irritating, the
Normal or Late warning distance settings can
be selected instead.
If the driver feels that the warnings are too fre-
quent and distracting, the warning distance can
be reduced. This will reduce the total number of
warnings, but it will also result in City Safety pro-
viding warnings at a later stage.

DRIVER SUPPORT
354Rear Collision Warning
The Rear Collision Warning (
RCW) function can
help the driver avoid rear-end collisions from
vehicles approaching from behind.
RCW is automatically activated each time the
engine is started.
RCW can warn the driver of a potential collision
with vehicles approaching from behind by rapidly
flashing the turn signals.
If, at a speed below 30 km/h (20 mph), the RCW
function detects that the car is in danger of being
hit from behind, the seatbelt tensioners may ten-
sion the front seatbelts and activate the Whiplash
Protection System safety system.
Immediately before a collision from behind, RCW
may also activate the foot brake in order to
reduce the forward acceleration of the car during
the collision. However, the brakes will only be
applied if your vehicle is stationary. The brakes
will be immediately released if the accelerator
pedal is depressed.

Rear Collision Warning limitations (p. 354)
Whiplash Protection System (p. 46) Rear Collision Warning limitations
In some situations, it may be difficult for RCW to
warn the driver of a collision risk.
This may be the case if: the vehicle approaching from the rear is
detected at a late stage
the vehicle approaching from the rear
changes lanes at a late stage
the vehicle approaching from the rear is mov-
ing at a speed above 80 km/h (50 mph)
a trailer, bicycle holder or similar is con-
nected to the vehicle's electrical system - the
RCW function will then be automatically
deactivated.
NOTE In certain markets RCW does not warn with
the direction indicators due to local traffic
regulations – in such cases, that part of the
function is deactivated.
NOTE The warning with direction indicators for Rear
Collision Warning is deactivated if the colli-
sion warning distance in the City Safety func-
tion is set to the lowest level "
Late".
The seat belt tensioning and braking func-
tions remain active.

CTA does not function optimally in all situations
and has certain limitations. The CTA sensors, for
example, cannot "see" through other parked
vehicles or objects blocking the vehicle.
Below are a few examples of situations in which
CTA's field of vision may be initially limited and
approaching vehicles may therefore not be
detected until they are very close to your vehicle: The vehicle is parked very far into a parking space. In a diagonal parking space, CTA may be completely
"blind" on one side of your vehicle.
