To start ACC:

•

The driver's seat belt must be buckled and
the driver's door must be closed.

•

There must be a vehicle ahead (target vehi-
cle) within a reasonable distance or your
vehicle's current speed must be at least
15 km/h (9 mph).

Note: This illustration is general and details may vary
depending on model.

–

With the

(4) function displayed, press

(1) on the steering wheel keypad.

> Adaptive Cruise Control will start and the

current speed will be stored, which will be
shown by numbers in the center of the
speedometer.

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).

Managing Adaptive Cruise Control

speed

Adaptive Cruise Control (ACC

) 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)

(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

button on the

steering wheel, the vehicle's speed when the but-
ton 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.

Automatic transmission

Adaptive Cruise Control can follow another vehi-
cle at speeds from a standstill up to 200 km/h
(125 mph).

The lowest speed that can be set for Adaptive
Cruise Control is 30 km/h (20 mph). When fol-
lowing 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).

The highest possible speed that can be set is
200 km/h (125 mph).

Setting Adaptive Cruise Control

time intervals

Adaptive Cruise Control (ACC

) can be set to

various time intervals to the vehicle ahead.

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 rep-
resents an interval of

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

The same symbol appears when the Distance
Alert function is activated.

When the symbol in the instrument panel
shows two vehicles, ACC is following the vehi-
cle ahead at a preset time interval.

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

Controls for setting a time interval

Reduce the time interval

Increase the time interval

Distance indicator

–

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

rent time interval.

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

•

The greater the vehicles' speed, the
greater the distance between them for a
set time interval.

•

Only use the time intervals permitted by
local traffic regulations.

•

If the Adaptive Cruise Control does not
seem to respond with a speed increase
when activated, it may be because the
time interval to the vehicle ahead is
shorter than the set time interval.

WARNING

•

Only use a time interval suitable for the
current traffic conditions.

•

The driver should be aware that short
time intervals give them limited time to
react and act to any unforeseen traffic
situation.

Setting how ACC should maintain
distance

* to the vehicle ahead

A number of different settings can be made for
how Adaptive Cruise Control should maintain a
time interval to the vehicle ahead. Settings are
made using the DRIVE MODE controls.

* Option/accessory.

270

Select one of the following:

•

Eco

- ACC will focus on providing optimal

fuel economy, which will increase the time
interval to the vehicle ahead.

•

Comfort

- ACC will focus on following the

set time interval to the vehicle ahead as
smoothly as possible.

•

Dynamic

- ACC will focus on following the

set time interval to the vehicle ahead more
exactly, which could mean faster acceleration
and heavier braking.

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

Automatic standby mode

Adaptive Cruise Control is dependent on other
systems, such as Electronic Stability Control
(ESC

). 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)

Reactivating Adaptive Cruise Control
from standby mode

Note: This illustration is general and details may vary
depending on model.

To reactivate ACC from standby mode:

–

Press the

button on the steering wheel

Passing assistance with Adaptive

Cruise Control

Adaptive Cruise Control (ACC

) can assist the

driver when passing other vehicles.

How passing assistance works

When ACC is following another vehicle and you
indicate that you intend to pass that vehicle by
using the turn signal

, 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.

•

Starting passing assistance with

Adaptive Cruise Control

Requirements for passing assistance

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 for ACC must be high
enough to safely pass another vehicle.

Starting parking assistance

To start passing assistance:

–

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

Related information

•

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

in standby mode.

Switching target vehicles with

Adaptive Cruise Control

At certain speeds, models with automatic trans-
missions and Adaptive Cruise Control (ACC

)

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.

Automatic braking with Adaptive

Cruise Control

The Adaptive cruise control (ACC

) 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.

Adaptive Cruise Control

DRIVER SUPPORT

274

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 Brake

In 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.

Adaptive Cruise Control limitations

Adaptive Cruise Control (ACC

) may have lim-

ited 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 interval 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
vehicle is carrying a heavy load or towing a
trailer.

Other limitations

•

The

Off Road

drive mode cannot be

selected if Adaptive Cruise Control is acti-
vated.

The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit limitations".
