310 Starting passing assistance with
Adaptive Cruise Control
Several conditions must be met for passing
assistance to be possible.
Requirements for passing assistanceIn 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 ACC 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 Adaptive Cruise
Control (p. 309) Limitations of passing assistance
with Adaptive Cruise Control
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 ACC 50
in standby mode.

Adaptive Cruise Control
At certain speeds, models with automatic trans-
missions and Adaptive Cruise Control (ACC 51
)
can switch target vehicles.
Switching target vehicles If the target vehicle ahead turns suddenly, there may be
stationary traffic ahead.
When Adaptive Cruise Control is actively follow-
ing another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a moving
vehicle to a stationary vehicle, Adaptive Cruise
Control will brake for the stationary vehicle. 50

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

Adaptive Cruise Control* (p. 300) Automatic braking with Adaptive
Cruise Control
The Adaptive cruise control (ACC
52
) has a spe-
cial brake function in slow traffic and while sta-
tionary.
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,
Adaptive Cruise Control will go into standby
mode and the Auto-hold brake function will acti-
vate.
– Adaptive Cruise Control can be reactivated in
one of the following ways:
Pressing the button on the steering
wheel keypad.
Pressing the accelerator pedal.
>

Adaptive Cruise Control will resume fol-
lowing the vehicle ahead if it begins to
move within approx. 6 seconds.
NOTE ACC can keep the vehicle stationary for no
more than 5 minutes – after that time the
parking brake is applied and Adaptive Cruise
Control is deactivated.
The parking brake must be released before
Adaptive Cruise Control 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 Adaptive
Cruise Control 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 sta-
tionary.
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 Adaptive Cruise Control in
standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will be
applied to keep the vehicle at a standstill. 51

316Pilot Assist
Pilot Assist helps the driver keep the vehicle in
the current traffic lane by providing steering
assistance and maintaining an even speed and a
set time interval to the vehicle ahead.
How Pilot Assist worksThe Pilot Assist function is primarily intended for
use on highways and other major roads where it
can help provide a more comfortable and relaxing
driving experience. The camera/radar sensor monitors the distance to the
vehicle ahead and detects lane markings
57
. Camera and radar sensor
Distance monitor
Lane marker line monitors The driver sets the desired speed and distance to
the vehicle ahead. Pilot Assist monitors the dis-
tance to the vehicle ahead and the traffic lane's
side markers using the camera and radar sensor.
The system maintains the set time interval to the
vehicle ahead by automatically adjusting your
vehicle's speed and keeps your vehicle in its lane
by providing steering assistance.
Pilot Assist's steering assistance is based on
monitoring the direction of the vehicle ahead and
the traffic lane's side marker lines. The driver can
override Pilot Assist's steering recommendations
at any time and steer in another direction, e.g. to
change lanes or avoid obstacles on the road.
If the camera/radar sensor cannot detect the
lane's side marker lines or if Pilot Assist is unable
for some other reason to clearly interpret the
lane, Pilot Assist will temporarily deactivate steer-
ing assistance until it can once again interpret
the lane markings. However, the speed and dis-
tance warnings will remain active.
WARNING
Pilot Assist is deactivated automatically and
resumes working without prior notice. The color of the steering wheel
symbol indicates the current
status of steering assistance:
• GREEN indicates that steer-
ing assistance is active
• GRAY (as shown in illustra-
tion) indicates that steering assistance is deacti-
vated. 57
Note: This illustration is general and details may vary depending on mod\
el.

With Adaptive Cruise Control in standby mode:
1. Press the ▶ button on the steering wheel (6).
>
The symbol will change to Pilot
Assist in standby mode (8).
2. Press the button on the steering wheel
(2).
>

Pilot Assist will start and the current
speed will be stored, which will be shown
by numbers in the center of the speedom-
eter.
...or...
With Adaptive Cruise Control started:
– Press the ▶ button on the steering wheel (6).
>

Pilot Assist will start.
Pilot Assist's steering assis-
tance is only active when the
steering wheel symbol (2)
changes from GRAY to
GREEN.
Pilot Assist will only regulate
the time interval to the vehicle ahead when the
distance symbol shows a vehicle (1) over the
steering wheel symbol. A speed interval will be marked
at the same time.
The higher speed is the set
speed for your vehicle and the
lower speed is the speed of the
vehicle ahead (target vehicle).
Hands on the steering wheelPilot Assist only functions if the driver's hands
are on the steering wheel.
If Pilot Assist detects that the
driver's hands are not on the
steering wheel, a symbol and
text message will appear to
instruct the driver to actively
steer the vehicle. If the driver's hands are still detected on the
steering wheel after a few seconds have passed,
the instructions to actively steer the vehicle will
be repeated, accompanied by an audible signal.
If Pilot Assist still does not detect the driver's
hands on the steering wheel after a few more
seconds have passed, the audible signal will
become intense and the steering function will
switch off. Pilot Assist must then be reactivated
by pressing the
button on the steering
wheel.
NOTE Note that the Pilot Assist function only works
when the driver's hands are on the steering
wheel.

322Managing Pilot Assist speed
Pilot Assist can be set to various speeds.
Setting/changing set speed
Note: This illustration is general and details may vary
depending on model and market.
: Increases the set speed
: Reduces the set speed
Set speed –
Change a set speed by pressing the (1)
or (2) buttons briefly or by pressing and
holding them:
Press briefly: Press briefly: each press
changes the speed in +/- 5 mph
(+/- 5 km/h) increments.
Press and hold: release the button when
the set speed indicator (3) has moved to
the desired speed.
The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button on
the steering wheel, the vehicle's speed when the
button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
Automatic transmission
Pilot Assist can follow another vehicle at speeds
from a standstill up to 200 km/h (125 mph).
The lowest speed that can be set for Pilot Assist
is 30 km/h (20 mph). When following another
vehicle, ACC can monitor that vehicle's speed
and slow your own vehicle down to a standstill,
but it is not possible to set speeds lower than
30 km/h (20 mph). The highest possible speed that can be set is
200 km/h (125 mph).

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.

Pilot Assist (p. 316) Passing assistance with Pilot Assist
Pilot Assist can assist the driver when passing
other vehicles.
How passing assistance worksWhen Pilot Assist is following another vehicle
and you indicate that you intend to pass that
vehicle by using the turn signal 62
, Pilot Assist will
begin accelerating toward the vehicle ahead
before your vehicle has moved into the passing
lane.
The function will then delay a speed reduction to
avoid early braking as your vehicle approaches a
slower-moving vehicle.
The function remains active until your vehicle has
passed the other vehicle.
WARNING Please note that this function can be acti-
vated in more situations than just passing
another vehicle, such as when a direction indi-
cator is used to indicate a lane change or
before exiting to another road – the vehicle
will then briefly accelerate.
