Change of target with driver

support

The driver supports of adaptive cruise con-
trol

*

and Pilot Assist

*

, in combination with

automatic transmission, have a change of tar-
get function at certain speeds.

Change of target

If the target vehicle in front suddenly turns then there

may be stationary traffic in front.

When the driver supports are following
another vehicle at speeds

below

30 km/h

(20 mph) and changes target vehicle – from a
moving vehicle to a stationary vehicle – the
driver supports will slow down for the station-
ary vehicle.

WARNING

When the driver supports are following

another vehicle at speeds

in excess of

approx. 30 km/h (20 mph) and the target

is changed from a moving vehicle to a sta-

tionary vehicle, the driver supports will

ignore

the stationary vehicle and instead

accelerate to the stored speed.

•

The driver must then intervene him/
herself and brake.

Automatic standby mode with change of
target

The driver supports are disengaged and set in
standby mode:

•

when the speed is below 5 km/h (3 mph)
and the driver supports are uncertain
whether the target object is a stationary
vehicle or another object, such as a speed
bump.

•

when the speed is below 5 km/h (3 mph)
and the vehicle ahead turns off so that the
driver supports no longer have a vehicle to
follow.

–

Change a set speed with short presses on
the steering wheel buttons

(1) or

(2) or by pressing and holding them.

•

Short

presses: Each press changes the

speed in increments of +/- 5 km/h
(+/- 5 mph).

•

Press

and

hold

: Release the button

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

> The speed set after the last button

press is stored in the memory.

Effect of the accelerator pedal

If the driver increases the car's speed using
the accelerator pedal before pressing the
steering wheel button

(1), the speed

stored will be the car's speed when the button
is depressed, provided the driver's foot is on
the accelerator pedal at the moment when the
button is depressed.

A temporary increase in speed with the accel-
erator pedal, e.g. during overtaking, does not
affect the setting - the car returns to the last
stored speed when the accelerator pedal is
released.

Possible speed

Automatic gearbox

The driver support functions can follow
another vehicle at speeds from 0 km/h up to
200 km/h (125 mph).

Pilot Assist can give steering assistance from
almost stationary up to 140 km/h (87 mph).

Note that the lowest programmable speed is
30 km/h (20 mph) – even though it is capable
of following another vehicle down to 0 km/h, a
speed lower than 30 km/h (20 mph) cannot
be selected/stored.

Manual gearbox

the driver support functions can follow
another vehicle at speeds from 30 km/h
(20 mph) up to 200 km/h (125 mph).

Pilot Assist can give steering assistance from
30 km/h (20 mph) up to 140 km/h (87 mph).

The lowest programmable speed is 30 km/h
(20 mph) – the maximum speed is 200 km/h
(125 mph).

functions.

Different time intervals to the
vehicle in front can be
selected and shown in the
driver display as 1-5 horizon-
tal lines - the more lines the
longer the time interval. One
line represents about 1 sec-

ond to the vehicle in front, 5 lines represents
about 3 seconds.

NOTE

When the symbol in the driver display
shows a car and a steering wheel, Pilot
Assist follows a vehicle in front at a preset
time gap.

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

NOTE

When the symbol in the driver display
shows two cars, adaptive cruise control is
following the vehicle in front at a pre-set
time interval.

When only one car is shown, there is no
vehicle within a reasonable distance ahead.

Control for time interval.

Decrease time interval

Increase time interval

Distance indicator

–

Press the steering wheel button (1) or (2)
to increase or decrease the time interval.
> The distance indicator (3) shows the

current time interval.

The adaptive cruise control allows the time
interval to vary significantly in certain situa-
tions in order to allow the car to follow the
vehicle in front smoothly and comfortably. At
low speed, when the distances are short, the
adaptive cruise control increases the time
interval slightly.

NOTE

•

The higher the speed the longer the
calculated distance in metres for a
given time interval.

•

Only use the time intervals permitted
by local traffic regulations.

•

If the driver supports do not seem to
respond with a speed increase when
activated, it may be because the time
window to the vehicle ahead is shorter
than the set time window.

WARNING

•

Only use a time window that suits the
current traffic conditions.

•

The driver should be aware that short
time windows limit the amount of time
available to react and take action in an
unexpected traffic situation.

The driver can select different driving styles
for how driver support should maintain the
preset time interval to the vehicle ahead.

Selection is made via the drive mode control

DRIVE MODE

.

Select one of the following options:

•

Pure

– The driver support focuses on

good fuel economy, which means longer
time interval to the vehicle ahead.

•

Hybrid

– The driver support focuses on

following the set time interval to the vehi-
cle ahead as smoothly as possible.

•

Power

– The driver support focuses on

following the set time interval to the vehi-
cle ahead more closely, which in certain
cases may mean heavier acceleration and
braking.

Automatic braking with driver

support

The driver supports of adaptive cruise con-
trol

*

and Pilot Assist

*

have a special brake

function in slow traffic and while stationary.
In certain situations, the parking brake is
applied in order to keep the car stationary.

Brake function in slow queues and
while stationary

For shorter stops in connection with inching in
slow traffic or at traffic lights, driving is auto-
matically resumed if the stops do not exceed
approx. 3 seconds - if it takes longer before
the vehicle in front starts moving again then
the driver support function is set in standby
mode with automatic braking.

–

The function is reactivated in one of the
following ways:

•

Press the steering wheel button

.

•

Depress the accelerator pedal.

> The function resumes following the

vehicle ahead if it starts moving for-
ward within approx. 6 seconds.

WARNING

A significant increase in speed may follow
when the speed is resumed with the

steering wheel button.

WARNING

Driver supports only warn of obstacles

which their radar unit has detected –

hence a warning may not be given, or it

may be given with a certain delay.

•

Never wait for a warning or interven-
tion. Apply the brakes when the situa-
tion requires.

NOTE

The driver supports can hold the car sta-
tionary for a maximum of 10 minutes –
then the parking brake is applied and the
function is disengaged.

Before the driver supports can be reactiva-
ted, the parking brake must be released.

331

Cessation of automatic braking

In some situations, automatic braking ceases
on coming to a standstill and the function is
set in standby mode. This means that the
brakes are released and the car may start to
roll - the driver must therefore intervene and
brake the car himself/herself to keep it station-
ary.

This may take place in any of the following sit-
uations:

•

The driver puts his/her foot on the brake
pedal.

•

The parking brake is applied.

•

The gear selector is moved to

P

,

N

, or

R

position.

•

The driver sets the adaptive cruise control
or Pilot Assist to standby mode.

Automatic activation of parking brake

The Parking brake is applied if the function is
holding the car stationary with the foot brake
and:

•

The driver opens the door or takes off
his/her seatbelt.

•

The function has kept the car stationary
for more than approx. 10 minutes.

•

The brakes have overheated.

•

The driver switches the engine off.

Lane assistance

The function of the Lane Keeping Aid (LKA

87

)

is to help the driver to reduce the risk of the
car accidentally leaving its own lane on
motorways and similar major routes.

Lane Keeping Aid steers the car back into its
lane and/or alerts the driver with vibrations in
the steering wheel.

Lane Keeping Aid is active within the speed
range 65–200 km/h (40–125 mph) on roads
with clearly visible side lines.

On narrow roads the function may be unavail-
able, in which case it goes into standby mode.
The function becomes available again when
the road is wide enough.

A camera reads the side lines of the road/lane.

Lane assistance steers the car back into its lane.

Lane assistance warns with steering wheel vibra-

tions.

Depending on settings, lane assistance acts in
accordance with the following:

•

Assist

activated: When the car is

approaching a lane line, the function will
actively steer the car back into its lane by

applying a slight torque to the steering
wheel.

•

Warning

activated: If the car is about to

cross a lane line, the driver is warned by
means of vibrations in the steering wheel.

There is also an option where both steering
assistance and warning are activated simulta-
neously.

NOTE

When a direction indicator/flasher is
switched on, there are no steering correc-
tions or alerts from lane assistance.

WARNING

•

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

•

•

Driver support functions are not a sub-
stitute for the driver's attention and
judgement. The driver is always
responsible for ensuring the car is
driven in a safe manner, at the appro-
priate speed, with an appropriate dis-
tance to other vehicles, and in accord-
ance with current traffic rules and reg-
ulations.

DRIVER SUPPORT

333

Lane assistance does not intervene

Lane assistance does not engage on sharp inside

curves.

In some situations, lane assistance allows lane
lines to be crossed without intervening with
either steering assistance or a warning – e.g.
when using the direction indicators or if the
car is allowed to cut the corners in bends.

Hands on the steering wheel

For steering assistance with lane assistance to
work, the driver must have his/her hands on
the steering wheel, which the system will con-
tinue to monitor.

If the driver does not keep
his/her hands on the steering
wheel, a warning signal is
heard and a message encour-
ages the driver to steer the
car actively:

•

Lane Keeping Aid

Apply steering

If the driver follows the prompt to start steer-
ing, the function is set in standby mode and
this message is shown:

•

) may have difficulty helping the

driver correctly. In such cases it is recom-
mended to switch off this function.

Examples of such conditions are:

•

road works

•

winter road conditions

•

poor road surface

•

a very “sporty” driving style

•

poor weather with reduced visibility

•

roads with unclear or non-existent side
markings

•

sharp edges or lines other than the lane's
side markings

•

as the steering servo for speed-dependent
steering wheel resistance is working at
reduced power – e.g. when cooling due to
overheating.

The function is unable to detect barriers, rails
or similar obstacles at the side of the carriage-
way.

NOTE

This function uses the car's camera and
radar units, which have certain general lim-
itations.

Steering assistance with brake intervention

Intervention with steering assistance and braking

Brake intervention helps in situations where
steering assistance alone is not sufficient. The
brake force is adapted automatically depend-
ing on the situation at the time of road run-off.

The function is active within the speed range
65-140 km/h (40-87 mph) on roads with
clearly visible lane markings/lines.

A camera scans the edges of the road and the
painted side markings. If the car is about to
leave the side of the road, the car is steered
back onto the road and if the steering inter-
vention is not enough to avoid run-off, the
brakes are also activated.

However, the function does

not

intervene with

either steering assistance or brake interven-
tion if the direction indicators are used. And if
the function detects that the driver is actively

driving the car, activation of the function will
be delayed.

rear-end collision can help a distracted driver
who does not notice that the car is about to
leave its own lane while an oncoming vehicle
is approaching at the same time, either from
behind or in the blind spot.

The function can assist by steering the car back to its

own lane.

Other vehicle in the blind spot

Your car

If the car is about to leave its own lane while
another vehicle is in the blind spot, or another
vehicle is approaching rapidly in an adjacent
lane at the same time, the function can help

the driver to steer the car back into its own
lane.

The function can even assist if the driver inten-
tionally changes lanes using direction indica-
tors without noticing that another vehicle is
approaching.

The function is active within the speed range

Limitations for steering assistance

at risk of collision

In certain situations the function may have
limited functionality and fail to intervene in
the following cases, for example:

•

for small vehicles, such as motorcycles

•

if the majority of the car has steered into
the adjacent lane

•

on roads/in lanes with unclear or non-exis-
tent lane markings

•

outside the speed range 60-140 km/h
(37-87 mph)

•

as the steering servo for speed-dependent
steering wheel resistance is working at
reduced power – e.g. when cooling due to
overheating.

Other demanding situations can include:

•

road works

•

winter road conditions

•

narrow roads

•

poor road surface

•

a very “sporty” driving style

•

poor weather with reduced visibility.

In these demanding situations, the function
may have difficulty helping the driver correctly.
In such cases it is recommended to switch off
this function.
