braking may come unexpectedly or not at

all.

Pilot Assist can help the driver to drive the

car between the lane's side markings as well

as to maintain an even speed, combined with

a preselected time interval to the vehicle

ahead.

follow the vehicle ahead in the same lane

at a time interval set by the driver. If the

radar unit cannot see any vehicle in front

then the car will instead maintain the

speed set and stored by the driver. This

also takes place if the speed of the vehicle

ahead increases and exceeds the stored

speed.

•

The Pilot Assist function is primarily intended

for use on motorways and similar major roads

where it can contribute to more comfortable

driving and a more relaxed driving experience.

Get to know Pilot Assist

The driver selects the desired speed and a

time interval to the vehicle ahead. Pilot Assist

scans the distance to the vehicle ahead and

the lane's side markings on the road surface

using the camera unit. The preset time interval

is maintained with automatic speed adjust-

ment whilst the steering assistance helps to

position the car in the lane.

Position of the car in the lane

When Pilot Assist helps to steer, it attempts to

place the car halfway between the visible lane

markings. For a smoother drive, it is a good

idea to allow the car to find a good position.

The driver can always adjust the position him/

herself by increasing the steering input. It is

important that the driver checks to make sure

the car is positioned safely in the lane.

Pilot Assist regulates the speed with accelera-

tion and braking. It is normal for the brakes to

emit a low sound when they are being used to

adjust the speed.

The camera and radar unit measures the distance to

the vehicle ahead and detects side markings.

If Pilot Assist does not position the car in an

appropriate way in the lane, it is recom-

mended to turn Pilot Assist off or switch to

adaptive cruise control*.

Pilot Assist strives to:

regulate the speed smoothly. In situations

that demand sudden braking the driver

must brake himself/herself. This applies in

cases of large speed differences or if the

car in front brakes suddenly. Due to the

limitations of the camera and radar unit,

If the driver's hands still cannot be detected

on the steering wheel after a few seconds, the

• GREY steering wheel (as in illustration) indi-

Pilot Assist steering assistance takes into

account the speed of the preceding car and

the lane markings. The driver can at any time

ignore the Pilot Assist steering recommenda-

tion and steer in another direction, e.g. to

change lane or avoid an obstruction on the

road.

When the car approaches an exit or if the lane

splits, the driver should steer towards the

desired lane so that Pilot Assist can detect the

desired direction.

If Pilot Assist cannot detect the driver's hands

on the steering wheel after a further few sec-

onds, the warning signal becomes intensive

and the steering function is deactivated. Pilot

Assist must then be restarted using the steer-

Hands on the steering wheel

In order for Pilot Assist to function, the driver’s

hands must be on the steering wheel. It is also

function may toggle between off and on with-

If Pilot Assist cannot interpret the lane unam-

biguously, e.g. if the camera and radar unit

does not see the lane's side markings, Pilot

Assist temporarily deactivates steering assis-

tance, but resumes it if the lane can be inter-

preted again - although the speed and dis-

tance control functions remain active. The

steering wheel vibrates slightly when deacti-

vated temporarily in order to alert the driver to

the change.

WARNING

•

Temporary disabling of steering

assistance with Pilot Assist*⁸³

Pilot Assist steering assistance can be tem-

porarily disabled and resumed without prior

warning.

When the direction indicators are used, Pilot

Assist steering assistance is temporarily dis-

engaged. When the direction indicator is

switched off, steering assistance is reactivated

automatically if the lane's edge markings can

still be detected.

With automatic standby mode, the driver is

warned via an acoustic signal and a mes-

sage on the driver display.

The speed is below 5 km/h (3 mph) and

the vehicle ahead turns off so that Pilot

Assist no longer has a vehicle to follow.

•

The driver must then regulate the car's

speed, apply the brakes as needed and

maintain a safe distance to other vehi-

cles.

Speed is reduced to below 30 km/h

(20 mph) - only applies to cars with man-

ual gearbox.

Limitations of Pilot Assist*⁸⁴

The Pilot Assist function may have limitations

with poor light conditions, back-light-

ing, wet road surface etc.

WARNING

In certain situations, Pilot Assist steering

assistance may have difficulty helping the

driver in the right way or it may be auto-

matically deactivated - in which case, the

use of Pilot Assist is not recommended.

Examples of such situations may be that:

The driver should also note that Pilot Assist

has the following limitations:

in certain situations.

The Pilot Assist function is an aid which can

help the driver in many situations. But the

driver is at all times responsible for maintain-

ing a safe distance to surrounding objects and

a correct position in the lane.

High kerbs, 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 car and

such obstacles. The driver must ensure

him/herself that the car is at a suitable

distance from such obstacles.

•

the lane markings are unclear, worn,

missing, or they cross each other, or if

there are several sets of lane markings.

•

the lane division is changed, e.g. when

the lanes split or merge, as well as on

slip roads.

The camera and radar sensor does not

have the capacity to detect all oncom-

ing objects and obstacles in traffic

formance.

Do not use Pilot Assist if the car has a heavy

load or a trailer is connected to the car.

WARNING

This is not a collision avoidance sys-

tem. The driver is always responsible

and must intervene if the system does

not detect a vehicle ahead.

•

Pilot Assist is switched off if the power

steering for speed related steering

force is working with reduced power –

e.g. during cooling due to overheating.

•

NOTE

Pilot Assist cannot be activated if a trailer,

bicycle rack or similar is connected to the

car's electrical system.

The function does not brake for

humans or animals, and not for small

vehicles such as bicycles and motorcy-

cles. Nor for low trailers, oncoming,

slow or stationary vehicles and objects.

WARNING

Drive mode unavailable

Off Road drive mode cannot be selected

when Pilot Assist is activated.

Pilot Assist must only be used if there are

clear lane lines painted on each side of the

lane. All other use involves increased risk of

contact with surrounding obstacles that

cannot be detected by the function.

Do not use the function in demanding

situations, such as in city traffic, at

junctions, 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 slip roads.

•

NOTE

This function uses the car's camera and

radar units, which have certain general lim-

itations.

The driver always has the possibility of cor-

recting or adjusting a steering intervention

imposed by Pilot Assist and can turn the steer-

ing wheel to the desired position.
