The Distance Alert 31
function can help the driver
become aware if the time interval to the vehicle
in front is too short.
However, the vehicle must be equipped with a
head-up display in order to display the Distance
Alert, which will then be indicated by a symbol
on the windshield as long as the time interval to
the vehicle ahead is shorter than the set time
interval.
Distance Alert is active at speeds above 30 km/h
(20 mph) and only reacts for vehicles ahead mov-
ing in the same direction as your vehicle. No dis-
tance information is provided for oncoming, slow-
moving or stationary vehicles. 29

ACC will only regulate the time
interval to the vehicle ahead
when the distance symbol
shows two vehicles.
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).

Adaptive Cruise Control* (p. 300) Managing Adaptive Cruise Control
speed
Adaptive Cruise Control (ACC 43
) 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. 42

To temporarily deactivate Adaptive Cruise Control
and put it in standby mode:
– Press the button on the steering wheel
(2).
> The symbol in the instrument panel
changes color from WHITE to GRAY and
the set speed in the center of the speed-
ometer will change from BEIGE to GRAY.
WARNING
If Adaptive Cruise Control is in standby
mode, the driver must intervene and regu-
late both speed and distance to the vehicle
ahead.
If the vehicle comes too close to a vehicle
ahead when Adaptive Cruise Control is in
standby mode, the driver is instead warned
of the short distance by the Distance Alert
function.
Standby mode due to action by the driver
Adaptive Cruise Control will be temporarily deac-
tivated and put in standby mode if:
the brakes are applied
the gear selector is moved to N
the vehicle is driven faster than the set
speed for more than 1 minute 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 standby mode
Adaptive Cruise Control is dependent on other
systems, such as Electronic Stability Control
(ESC
47
). If any of these other systems stops
working, Adaptive Cruise Control will automati-
cally switch off.
WARNING With automatic standby mode, the driver is
warned by an acoustic signal and a message
on the instrument panel.

The driver must then regulate vehicle
speed, apply the brakes if necessary, and
maintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standby
mode if: your vehicle's speed goes below 5 km/h
(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.
the parking brake is applied.
the camera/radar sensor is covered by snow
or heavy rain (the camera lens/radar waves
are blocked)

Adaptive Cruise Control* (p. 300) Passing assistance with Adaptive
Cruise Control
Adaptive Cruise Control (ACC
48
) 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 49
, 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.

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
