Pilot Assist can be deactivated and put in
standby mode. This may happen automati-
cally or be due to driver intervention.

Standby mode means that the function is
selected in the instrument panel but not acti-
vated. In standby mode, Pilot Assist will not
regulate the speed or distance to the vehicle
ahead or provide steering assistance.

driver

Pilot Assist will be deactivated and put in
standby mode if any of the following occurs:

•

The brakes are applied.

•

The gear selector is moved to

•

A turn signal is used for more than
1 minute.

•

The vehicle is driven faster than the set
speed for more than 1 minute.

Automatic standby mode

WARNING

With automatic standby mode, the driver is

warned by an acoustic signal and a mes-

sage on the instrument panel.

•

The driver must then regulate vehicle
speed, apply the brakes if necessary,
and maintain a safe distance to other
vehicles.

The function may automatically go into
standby mode if one of the following occurs.

•

One of the systems that Pilot Assist is
dependent on stops working, such as
Electronic Stability Control

•

The driver's hands are not on the steering
wheel.

•

The driver opens the door.

•

The driver unbuckles the seat belt.

•

Temporarily deactivating steering

assistance with Pilot Assist

Pilot Assist steering assistance can be tem-
porarily deactivated and reactivated without
prior warning.

When the turn signals are used, Pilot Assist's
steering assistance will be temporarily deacti-
vated. When the direction indicator is turned
off, steering assistance is reactivated automat-
ically if the lane's edge markings can still be
detected.

If Pilot Assist cannot clearly interpret the
lane's side marker lines or if the camera/radar
sensor is unable for some other reason to
clearly interpret the lane, Pilot Assist will tem-
porarily deactivate steering assistance. How-
ever, the speed and distance warnings will
remain active. Steering assistance will resume
when the side marker lines can once again be
interpreted. In these situations, the driver may
be alerted through slight vibrations in the
steering wheel that steering assistance is tem-
porarily deactivated.

Pilot Assist

limitations

Pilot Assist functionality may be reduced in
certain situations.

Pilot Assist is a driver support function
designed to simplify driving and assist the
driver in many situations. However, the driver
is always responsible for maintaining a suita-
ble distance to vehicles or objects around it
and ensuring that the vehicle is correctly posi-
tioned in the traffic lane.

WARNING

In some situations, Pilot Assist may have

trouble 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 unclear, worn,
missing, cross each other, or there are
multiple sets of road markings.

•

the lane division changes, e.g. when
lanes split or merge, and at off-ramps.

•

when there is road construction and
sudden changes to the road surface,
e.g. when the lines may no longer mark
the correct route.

•

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 visibil-

ity with poor light conditions, back-
lighting, wet road surface, etc.

The driver should also note that Pilot Assist

has the following limitations:

•

High curbs, roadside barriers, tempo-
rary obstacles (traffic cones, safety bar-
riers, etc.) are not detected. Alterna-
tively, they may be detected incorrectly
as lane markings, with a subsequent
risk of contact between the vehicle and
such obstacles. The driver is responsi-
ble for ensuring that the vehicle main-
tains a suitable distance from such
obstacles.

•

The camera and radar sensors do not
have the capacity to detect all oncom-
ing objects and obstacles in traffic
environments, e.g. potholes, stationary
obstacles or objects that completely or
partially block the route.

•

Pilot Assist does not "see" pedestrians,
animals, etc.

•

The steering assistance is limited in
force, which means that Pilot Assist
cannot always help the driver to steer
and keep the vehicle within the lane.

•

In vehicles equipped with Sensus
Navigation

, the function is able to use

Depending on market, this function can be either standard or optional.

information from map data, which
could cause variations in performance.

•

Pilot Assist will be switched off if the
speed-dependent power steering
wheel resistance is working at reduced
power, e.g. during cooling due to over-
heating.

WARNING

Pilot Assist should only be used if there are

clear lane lines painted on each side of the

lane. All other use will increase the risk of

contact with nearby obstacles that cannot

be detected by the functions.

WARNING

•

This is not a collision avoidance sys-
tem. The driver is always responsible
and must intervene if the system fails
to detect a vehicle ahead.

•

The function does not brake for people
or animals and does not brake for small
vehicles, such as bikes and motorcy-
cles. Similarly, it does not brake for low
trailers, oncoming, slow-moving or sta-
tionary vehicles and objects.

•

Do not use the function in demanding
situations, such as in city traffic, at
intersections, on slippery surfaces,
with a lot of water or slush on the road,
in heavy rain/snow, in poor visibility, on
winding roads, or on on/off ramps.

The driver can always correct or adjust steer-
ing assistance provided by Pilot Assist by turn-
ing the steering wheel to the desired position.

Steep roads and/or heavy loads

Pilot Assist is primarily intended to be driven
on flat roads. The function may not be able to
maintain the correct time interval to the vehi-
cle ahead when driving down steep hills. The
driver should be extra attentive and prepared
to apply the brakes.

Do not use Pilot Assist if the vehicle is carrying
a heavy load or towing a trailer.

Pilot Assist cannot be activated if a trailer,
bike carrier or similar is connected to the
vehicle electrical system.

Drive mode unavailable

The

Off Road

drive mode cannot be selected

when Pilot Assist is activated.

The function uses the vehicle's camera and
radar sensor, which has certain general
limitations.

Curve Speed Assist (CSA)

Curve Speed Assist

can help the driver

reduce speed before sharp turns if the preset
speed for the driver support function Adap-
tive Cruise Control

or Pilot Assist

is deter-

mined to be too high.

As the function reduces the
vehicle's speed, this symbol
will be displayed in the instru-
ment panel.

This assessment is performed using informa-
tion from map data in the vehicle's navigation
system, Sensus Navigation

. After the turn,

the vehicle will resume the previously set
speed.

The driver can cancel the function at any time
by braking or using the accelerator pedal.

WARNING

•

The function is supplementary driver
support intended to facilitate driving
and help make it safer – it cannot han-
dle all situations in all traffic, weather
and road conditions.

•

Driver support functions are not a sub-
stitute for the driver's attention and
judgment. The driver is always respon-
sible for ensuring the vehicle is driven
in a safe manner, at the appropriate
speed, with an appropriate distance to
other vehicles, and in accordance with
current traffic rules and regulations.

Drive modes

Cornering assistance varies depending on the
selected drive mode. If drive mode cannot be
selected, the function will use the

Comfort

option. In

Dynamic

mode, cornering will be

sporty, with slightly more powerful accelera-
tion coming out of curves.

Passing assistance

Passing assistance can assist the driver when
passing other vehicles. The function can be
used with Adaptive Cruise Control

or Pilot

Assist

When Adaptive Cruise Control or Pilot Assist
is following another vehicle and you indicate
that you intend to pass that vehicle by using
the turn signal

, the system will begin accel-

erating 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

indicator is used to indicate a lane change

or before exiting to another road – the vehi-

cle will then briefly accelerate.

WARNING

•

The function is supplementary driver
support intended to facilitate driving
and help make it safer – it cannot han-
dle all situations in all traffic, weather
and road conditions.

or Pilot Assist

. Several

conditions must be met for passing assis-
tance 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

must be high enough to

safely pass another vehicle.

To start passing assistance:

–

Turn on the left turn signal.
> Passing assistance will start.

WARNING

The driver should be aware that if condi-

tions suddenly change when using Passing

Assistance, the function may implement an

undesired acceleration in certain condi-

tions.
Some situations should be avoided, e.g. if:

•

the vehicle is approaching an exit in the
same direction as passing would nor-
mally occur

•

the vehicle ahead slows before your
vehicle has had time to switch to the
passing lane

•

traffic in the passing lane slows down

Situations of this type can be avoided by

temporarily putting Adaptive Cruise Control

or Pilot Assist in standby mode.

Collision risk warning from driver

support

The driver support systems Adaptive Cruise
Control

and Pilot Assist

can help alert the

driver if the distance to the vehicle ahead
suddenly decreases to an unsafe distance.

Collision warning audible signal and symbol

Audible signal at risk of collision

Collision warning symbol

Camera/radar sensor distance monitoring

Adaptive Cruise Control and Pilot Assist use
approx. 40% of the braking capacity. If a sit-
uation requires more braking force than driver
support can provide, and if the driver does not
apply the brakes, a warning light and audible
warning signal will be activated to alert the
driver that immediate action is required.

WARNING

The driver support system only issues a

warning for vehicles detected by its radar

unit – thus, a warning may come after a

delay or not at all. Never wait for a warning.

Apply the brakes when necessary.

Collision warning symbol on the windshield

In vehicles equipped with a head-up display

a flashing warning symbol will be displayed on
the windshield.

Visual warnings on the windshield may be
difficult to notice in cases of strong sun-
light, reflections, extreme light contrasts,
or if the driver is wearing sunglasses or is
not looking straight ahead.

Switching target vehicles with

driver support

At certain speeds, vehicles with automatic
transmissions and the driver support func-
tions Adaptive Cruise Control

and Pilot

Assist

can switch target vehicles.

Switching target vehicles

If the target vehicle ahead turns suddenly, there may

be stationary traffic ahead.

When driver support is actively following
another vehicle at speeds

under

30 km/h

(20 mph) and switches targets from a moving
vehicle to a stationary vehicle, driver support
will brake for the stationary vehicle.

WARNING

When driver support follows another vehi-

cle at speeds

over

approx. 30 km/h

(20 mph) and changes target vehicle –

from a moving vehicle to a stationary one –

driver support 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

Driver support disengages and goes into
standby mode if:

•

your vehicle's speed goes under 5 km/h
(3 mph) and driver support cannot deter-
mine if the target vehicle 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 driver support no longer has a vehicle
to follow.

: Reduces the set speed

Set speed

–

Change a set speed by pressing the
(1) or

(2) buttons briefly or by pressing

and holding them:

•

Brief

press: Each press changes the

speed in +/- 5 km/h (+/- 5 mph) incre-
ments.

•

Press

hold

: Release the button

when the set speed indicator (3) has
moved to the desired speed.

> The most recently set speed will be

stored.

For vehicles without Adaptive Cruise Con-
trol

, speed instead increases by +/- 1km/h

(+/- 1 mph) each time the button is
pressed.

Pressing the accelerator pedal

If speed is increased by depressing the accel-
erator 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 accel-
erator pedal, e.g. when passing another vehi-
cle, will not affect the setting. The vehicle will
return to the set speed when the accelerator
pedal is released.

Possible speed

Automatic transmission

The driver support functions can follow
another vehicle at speeds from a standstill up
to 200 km/h (125 mph).

Pilot Assist can provide steering assistance
from near-stationary speeds up to 140 km/h
(87 mph).

The lowest speed that can be set 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).

Setting time interval to the vehicle

ahead

The time interval to the vehicle ahead can be
set for the functions Adaptive Cruise Control

Pilot Assist

and Distance Alert

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 represents an interval of

approx. 1 second to the vehicle ahead. 5 bars
represents approx. 3 seconds.

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 reasona-
ble distance.

When the symbol in the instrument panel
shows two vehicles, Adaptive Cruise Con-
trol is following the vehicle ahead at a pre-
set time interval.

When only one vehicle is shown, there is
no vehicle ahead within a reasonable dis-
tance.

Controls for setting a time interval.

In order to help your vehicle follow the vehicle
ahead as smoothly and comfortably as possi-
ble, Adaptive Cruise Control allows the time
interval to vary noticeably in certain situations.
At low speeds, when the distance to the vehi-
cle ahead is short, Adaptive Cruise Control
increases the time interval slightly.
