DRIVER SUPPORT
* Option/accessory.
272 Driver support systems
The vehicle is equipped with a number of driver
support systems that can provide the driver with
active or passive assistance in various situations.
The system can, for example, help the driver
maintain a set speed or a set time interval to the
vehicle ahead, help prevent a collision by warning
the driver and applying the brakes, or assist the
driver while parking.
Some of the systems are standard and others are
options. This also varies from market to market.

resistance
Speed-dependent power steering increases the
steering wheel resistance in pace with the vehi-
cle's speed to give the driver an enhanced feel-
ing of control and stability.
Steering may feel stiffer on highways. When
parking and at low speeds, it will be easier to
move the steering wheel.
NOTE In some situations, the power steering may
become too hot and require temporary cool-
ing – during such time the power steering will
work at reduced output and the steering
wheel may feel more difficult to move.
In parallel with the temporarily reduced steer-
ing assistance, the driver display shows a
message as well as a STEERING WHEEL
symbol.

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 50
). 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)

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 53
in standby mode.

Adaptive Cruise Control
At certain speeds, models with automatic trans-
missions and Adaptive Cruise Control (ACC 54
)
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.
WARNING When 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.

306 Automatic braking with Adaptive
Cruise Control
The Adaptive cruise control (ACC
55
) 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. This occurs if Adaptive Cruise Control is keeping
the vehicle stationary using the brakes and:
• the driver opens the door or unbuckles
his/her seat belt
• ACC has kept the vehicle at a standstill for
more than approx. 5 minutes
• the brakes overheat
• the driver switches off the engine manually.

Related information
•Pilot Assist (p. 311) Pilot Assist limitations
Pilot Assist functionality may be reduced in cer-
tain situations.
Pilot Assist is a driver support function designed
to simplify driving and assist the driver in many
situations. However, the driver is always responsi-
ble for maintaining a suitable distance to vehicles
or objects around it and ensuring that the vehicle
is correctly positioned in the traffic lane.
WARNING In some situations, Pilot Assist may have trou-
ble helping the driver properly or may be
deactivated automatically – we advise against
using Pilot Assist in such cases. Examples of
such situations include:
• the lane markings are worn, missing or
cross each other.
• lane division is unclear, for example, when
the lanes divide or merge or at exits or
when there are multiple sets of markings.
• edges or other lines than lane markings
are present on or near the road, e.g.
curbs, joints or repairs to the road sur-
face, edges of barriers, roadside edges or
strong shadows.
• the lane is narrow or winding.
• the lane contains ridges or holes.
• weather conditions are poor, e.g. rain,
snow or fog or slush or reduced visibility
with poor light conditions, backlighting,
wet road surface, etc.
The driver should also note that Pilot Assist
has the following limitations:
• High curbs, roadside barriers, temporary
obstacles (traffic cones, safety barriers,
etc.) are not detected. Alternatively, they
may be detected incorrectly as lane mark-
ings, with a subsequent risk of contact
between the vehicle and such obstacles.
