Adaptive Cruise Control

limitations

Adaptive Cruise Control (ACC

) may have

limited functionality in certain situations.

Steep roads and/or heavy loads

Adaptive Cruise Control is primarily intended
to be driven on flat roads. The function may
not be able to maintain the correct time inter-
val to the vehicle ahead when driving down
steep hills. The driver should be extra attentive
and prepared to apply the brakes.

Do not use Adaptive Cruise Control if the vehi-
cle is carrying a heavy load or towing a trailer.

Drive mode unavailable

The

Off Road

drive mode cannot be selected

if Adaptive Cruise Control is activated.

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.

NOTE

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

Pilot Assist

Pilot Assist can help the driver keep the vehi-
cle in the current traffic lane and maintain an
even speed and a set time interval to the
vehicle ahead.

Get to know Pilot Assist

The camera/radar sensor monitors the distance to

the vehicle ahead and detects lane markings.

Camera and radar sensor

Distance monitor

Lane marker line monitors

Pilot Assist helps to steer the vehicle, and you
may need to drive a few miles with Pilot Assist
before you feel completely at home with the
function. It is important to be familiar with all

of the function's applications and limitations in
order to take advantage of all it has to offer.

The 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 driver sets the desired speed and distance
to the vehicle ahead. Pilot Assist monitors the
distance to the vehicle ahead and the traffic
lane's side markers using the camera. The sys-
tem maintains the set time interval to the vehi-
cle ahead by automatically adjusting your vehi-
cle's speed and keeps your vehicle in its lane
by providing steering assistance.

If the Curve Speed Assist (CSA)

function is

activated, it may also affect the vehicle's
speed.

Pilot Assist regulates speed by accelerating
and braking. It is normal for the brakes to emit
a slight sound when they are being used to
adjust speed.

Pilot Assist is designed to:

•

smoothly regulate speed. The driver must
apply the brakes in situations requiring
immediate braking. For example, when
there are great differences in speed
between vehicles or if the vehicle ahead
brakes suddenly. Due to limitations in the

camera and radar sensor, braking may
occur unexpectedly or not at all.

•

follow a vehicle ahead in the same lane
and maintain a time interval to that vehicle
set by the driver. If the radar sensor does
not detect a vehicle ahead, it will instead
maintain the speed set by the driver. This
will also happen if the speed of the vehicle
ahead exceeds the set speed for your vehi-
cle.

The vehicle's position in the traffic
lane

When Pilot Assist helps to steer, it attempts to
position the vehicle halfway between the visi-
ble lane marking lines. For a smoother drive, it
is a good idea to allow the vehicle to find a
good position. The driver can always adjust
the position him/herself by increasing steering
input. It is important for the driver to make
sure the vehicle is positioned safely in the lane.

If Pilot Assist does not position the vehicle
appropriately in the lane, the driver should turn
off Pilot Assist or switch to Adaptive Cruise
Control

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

Steering assistance

The color of the steering
wheel symbol indicates the
current status of steering
assistance:

• GREEN indicates that
steering assistance is active

• GRAY (as shown in illustration) indicates that
steering assistance is deactivated.

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 rec-
ommendations 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 inter-
pret the lane, Pilot Assist will temporarily
deactivate steering assistance until it can once
again interpret the lane markings. However,
the speed and distance warnings will remain
active. The driver will be alerted by slight
vibrations in the steering wheel that the func-
tion has been temporarily deactivated.

WARNING

Pilot Assist is deactivated automatically

and resumes working without prior notice.

In curves and forks in the road

Pilot Assist is designed to interact with the
driver. The driver should never wait for steer-
ing assistance from Pilot Assist, but instead
should always be ready to increase his or her
own steering efforts, particularly in curves.

When the vehicle is approaching an off-ramp
or a fork in the road, the driver should steer
toward the desired lane so that Pilot Assist
can detect the desired direction of travel.

Hands on the steering wheel

Pilot Assist only functions if the driver's hands
are on the steering wheel. It is also important
for the driver to always continue to be active
and alert when driving since Pilot Assist is
unable to read all situations and may toggle
between off and on without prior warning.

If Pilot Assist detects that the
driver's hands are not on the
steering wheel, the system
will provide a symbol and a
text message in the instru-
ment panel 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 reactiva-
ted by pressing the

button on the steering

wheel.

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.

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.
