288Managing Cruise Control speed
Cruise Control (CC 29
) can be set to various
speeds.
Setting/changing set speed Note: This illustration is general and details may vary
depending on model.
For vehicles with only CC
–
Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing and
holding them:
• Press briefly: Press briefly: each press
changes the speed in +/- 1 mph
(+/- 1 km/h) increments.
• Press and hold: Release the button when
the set speed indicator (4) 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.
For vehicles with both CC and ACC
– Change a set speed by pressing the (1)
or (3) 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 (4) 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.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applying
the brakes. On downgrades, it can sometimes be
desirable to roll a bit faster and let speed be
reduced instead by engine braking alone. The
driver can temporarily disengage the Cruise Con-
trol braking function.
To disengage CC:
– Press the accelerator pedal about halfway
down and then release it.
>

Cruise Control will automatically disen-
gage the automatic brake function and
speed will only be reduced using the
engine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle's
speed can vary depending on the selected drive
mode 30
. 29

Cruise Control Eco Cruise
In the ECO drive mode, cruise control's accelera-
tion and deceleration will be smoother than in
other drive modes to help provide optimal fuel
efficiency and reduced environmental impact.
Because of this, the vehicle's actual speed may
be slightly above or below the set speed.
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control's
acceleration and deceleration will be faster and
more immediate than in other drive modes.

(3 mph) and ACC cannot determine if the
vehicle ahead is stationary or if it is 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
ACC no longer has a vehicle to follow. •
the driver opens the door.
• the driver unbuckles the seat belt.
• the engine speed (rpm) is too low/high.
• one or more of the wheels lose traction.
• the brake temperature is high.

Adaptive Cruise Control* (p. 295) Passing assistance with Adaptive
Cruise Control
Adaptive Cruise Control (ACC
51
) can assist the
driver when passing other vehicles.
How passing assistance worksWhen ACC is following another vehicle and you
indicate that you intend to pass that vehicle by
using the turn signal 52
, Adaptive Cruise Control
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.

Pilot 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
62
. 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. 62
Note: This illustration is general and details may vary depending on mod\
el.

– 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, the driver will be instructed to actively
steer the vehicle by a text message and an audi-
ble signal.
If Pilot Assist still cannot detect the driver's
hands on the steering wheel, the function will go
into standby mode. 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.

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).

Pilot Assist (p. 311) Setting a time interval for Pilot
Assist
Pilot Assist
can be set to different time intervals.
Different time intervals to the
vehicle ahead can be selected
and are shown in the instru-
ment panel as 1–5 horizontal
bars. The more bars, the longer
the time interval. One bar rep-
resents an interval of
approx. 1 second to the vehicle ahead. 5 bars
represents approx. 3 seconds.
NOTE When the symbol in the instrument panel
shows a vehicle and a steering wheel, Pilot
Assist follows a vehicle ahead at a preset
time interval.
When only a steering wheel is shown, there is
no vehicle ahead within a reasonable dis-
tance.
