Automatic braking with Pilot

Assist-1

The auto-hold brakes function as follows with
Pilot Assist.

Auto-hold brake function

In slow-moving, stop-and-go traffic or when stop-
ped at a traffic light, driving will resume automati-
cally if the vehicle is not stopped for more than
approx. 3 seconds. If it takes more than
3 seconds for the vehicle ahead to begin moving
again, Pilot Assist will go into standby mode and
the auto-hold brake function will activate.

–

The driver will then have to reactivate Pilot
Assist in one of the following ways:

•

Press the

button on the left-side

steering wheel keypad

•

Press the accelerator pedal

> Pilot Assist will resume following the vehi-

cle ahead (target vehicle) if it begins to
move within approx. 6 seconds.

NOTE

Pilot Assist can keep the vehicle at a stand-
still for up to 5 minutes, after which the park-
ing brake will be set and Pilot Assist will go
into standby mode.

The parking brake has to be released before
Pilot Assist 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 Pilot Assist
will go into standby mode.

This means that the brakes will be released and
the vehicle can begin to roll.

The driver must actively apply the brakes to keep
the vehicle at a standstill.

This can occur in the following situations:

•

the driver presses the brake pedal

•

the parking brake is set

•

the gear selector is moved to the P, N or R
positions

•

the driver puts Pilot Assist in standby mode

Automatically setting the parking brake

In certain situations, the parking brake is set
automatically to help keep the vehicle at a stand-
still.

This occurs if:

•

the driver unbuckles the seat belt or opens
the door

•

Pilot Assist has kept the vehicle at a stand-
still for more than approx. 5 minutes

•

the engine is turned off

•

the brakes overheat

Pilot Assist-1 limitations

Pilot Assist functionality may be limited in certain
situations.

Pilot Assist is designed to help the driver in a
number of situations. However, the driver always
has the primary responsibility for maintaining a
safe distance to other vehicles and for keeping
the vehicle in its proper traffic lane.

WARNING

Pilot Assist is not a collision avoidance sys-
tem. The driver is always responsible for
steering or applying the brakes if the system
does not detect another vehicle.

Do not use Pilot Assist in demanding driving
conditions such as city driving or other heavy
traffic situations, in slippery conditions, when
there is a great deal of water or slush on the
road, during heavy rain or snow, in poor visibil-
ity, on winding roads or on highway on- or off-
ramps.

In certain situations, it may be difficult for Pilot
Assist to assist the driver correctly or to deac-
tivate automatically. In such cases, it is advisa-
ble not to use Pilot Assist. Examples of such
situations may be:

•

the lane's side market lines are missing,
badly faded or cross each other.

•

the division of lanes is not clear, e.g.,
when a line divides or merges with
another, at exits or if there are many road
signs/markers.

•

there are edges or other lines on or near
the lane, e.g., curbs, cracks, repaired
areas, sharp shadows, etc.

•

the lane is narrow or winding.

•

the lane is at the top of a hill, on an
uneven road surface or over a bump.

•

bad weather conditions (rain, snow, fog,
slush, poor visibility, backlighting, etc).

The driver should also be aware that Pilot
Assist has the following limitations:

•

High curbs, barriers and temporary obsta-
cles (cones, barriers etc) may not be
detected or could be detected incorrectly
as side marker lines, which may create a
risk of collision. The driver must ensure a
safe distance to these obstacles.

•

The camera or radar sensor may not be
able to detect objects if there are pot-
holes or if there are stationary objects
partially or completely blocking the road.

•

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

•

Pilot Assist's steering capacity is limited
and may not always be able to help the
driver keep the vehicle in the lane.

The driver can always take action to override Pilot
Assist.

Steep roads and/or heavy loads

Pilot Assist is primarily intended for use on rela-
tively level roads. The function may not be able to
maintain the correct time interval to the vehicle
ahead on when driving down steep hills. The
driver should be attentive and prepared to apply
the brakes in these situations.

Do not use Pilot Assist when the vehicle is trans-
porting a heavy load or if it is towing a trailer.

Additional information

•

The

Off Road

drive mode cannot be

selected if Pilot Assist is activated.

Pilot Assist uses the vehicle's camera and
radar sensor, which have certain general limi-
tations. See the articles "Camera limitations"
and "Radar sensor limitations" for additional
information.

Pilot Assist-2

The Pilot Assist feature helps keep the vehicle in
its current traffic lane by providing steering
assistance and maintaining an even speed and a
set time interval to the vehicle ahead.

Function

Pilot Assist helps provide more relaxed driving on
long trips on highways or other major roads in an
even flow of traffic.

Function overview (generic illustration)

Windshield module containing the camera/
radar sensor
Monitoring distance

Monitoring side marker lines

The driver sets the desired time interval to the
vehicle ahead. Pilot Assist monitors that vehicle
and the traffic lane's side market lines using the

camera and radar sensor mounted in the upper,
center section of the windshield. It helps maintain
the set time interval by automatically adjusting
speed and by providing steering assistance to
help keep your vehicle in the lane.

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
always override Pilot Assist and steer the vehicle
to e.g., change lanes, etc.

If the camera and radar sensor cannot detect the
lane's side marker lines, Pilot Assist will tempo-
rarily switch off the steering assistance until the
lane's side marker lines become visible again and
can be detected. However, the function's speed
and distance monitoring will continue to be acti-
vated.

WARNING

Pilot Assist's steering assistance may switch
on or off without warning.

The color of the steering wheel
symbol indicates the current
status of the steering assis-
tance function:

WHITE: steering assistance is
active

GRAY (as in the illustration): steering assistance
is deactivated

DRIVER SUPPORT

306

WARNING

•

Pilot Assist is designed to be a supple-
mentary driving aid and cannot cover all
driving situations, traffic, weather and/or
road conditions.

•

The driver should be familiar with all of
the information in this article regarding
Pilot Assist, including its limitations.

•

Pilot Assist is not intended to replace the
driver's attention and judgement.

•

Pilot Assist must only be used where
there are clearly visible traffic lane side
marker lines on both sides of the current
traffic lane. In other circumstances there
is an increased risk of collision with sur-
rounding obstacles that are not detected
by the system.

•

The driver is always responsible for steer-
ing the vehicle and maintaining a suitable
speed and distance to the vehicle ahead
and must intervene if necessary, even if
Pilot Assist is being used.

Pilot Assist attempts to regulate speed smoothly
but in situations calling for fast braking, the driver
must apply the brakes. This applies to situations
where there are considerable differences in
speed or if the vehicle ahead brakes suddenly.
Due to the limitations of the camera and radar
sensor, the system may apply the brakes in your
vehicle suddenly or not at all.

Pilot Assist is designed to follow a vehicle ahead
in the same traffic lane at a preset time interval
set by the driver. If the radar sensor does not
detect a vehicle ahead, the vehicle will instead
maintain the speed set by the driver. This will also
be the case if a vehicle ahead accelerates and
exceeds the set speed.

•

Pilot Assist can follow another vehicle from a
standstill up to a speed of approx. 125 mph
(200 km/h)

•

Pilot Assist can provide steering assistance
from very low speeds up to approx. 87 mph
(140 km/h).

Never exceed posted speed limits.

WARNING

•

Pilot Assist is not a collision avoidance
system. The driver must react if the sys-
tem does not detect another vehicle.

•

Pilot Assist does not react to people, ani-
mals, stationary objects, small vehicles
(such as bicycles and motorcycles), low
trailers and slow moving, parked or
approaching vehicles.

•

Do not use Pilot Assist in demanding
driving conditions such as city driving or
other heavy traffic situations, in slippery
conditions, when there is a great deal of
water or slush on the road, during heavy
rain or snow, in poor visibility, on winding
roads or on highway on- or off-ramps.

NOTE

•

Pilot Assist maintenance should only be
carried out by a trained and qualified
Volvo service technician.

•

Pilot Assist regulates your vehicle's
speed using the accelerator pedal and
the brakes. Please be aware that there
may be a faint sound from the brakes
when the system is using them.

Collision warning

Warning light in the windshield

Pilot Assist can exert brake force that is equiva-
lent to approximately 40% of the vehicle's total
braking capacity.

In situations requiring more brake force than Pilot
Assist can provide and if the driver does not
apply the brakes, an audible signal and warning
light will illuminate in the windshield to alert the
driver to react.

NOTE

Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the vis-
ual warning signal in the windshield difficult to
see.

DRIVER SUPPORT

* Option/accessory, for more information, see Introduction.

308

WARNING

Pilot Assist only provides warnings for vehi-
cles that its radar sensor and camera have
detected. For this reason, a warning may be
given later than expected or not at all. The
driver should never wait for a warning before
applying the brakes.

Head-up-display

A flashing symbol alerts the driver

If the vehicle is equipped with a head-up display,
a flashing symbol in the windshield will alert the
driver.

NOTE

Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the vis-
ual warning signal in the windshield difficult to
see.

Setting a Pilot Assist-2 time interval

Different time intervals to the vehicle ahead can
be selected and are shown in the instrument
panel as 1–5 horizontal bars.

Changing the time interval

The greater the number of bars,
the longer the time interval.
One bar between the vehicles
represents a time interval of
approximately 1 second; 5 bars
is approximately 3 seconds.

NOTE

When the graphic in the instrument panel
shows a vehicle and a steering wheel, Pilot
Assist is following a vehicle ahead using the
set time interval.

If only a steering wheel is displayed, there is
no vehicle ahead within a reasonable dis-
tance.

DRIVER SUPPORT

* Option/accessory, for more information, see Introduction.

312

Time interval controls

Press to reduce the time interval to the vehi-
cle ahead
Press to increase the time interval to the
vehicle ahead
Distance indicator

In order to follow the vehicle ahead as smoothly
as possible, Pilot Assist allows the time interval to
vary considerably in certain situations. At low
speeds, when the distance to the vehicle ahead
is short, Pilot Assist increases the time interval
slightly.

•

If Pilot Assist does not seem to react when it
is put in active mode, this may be because
the set time interval to the vehicle ahead
does not allow an increase in speed.

•

The higher the speed, the greater the dis-
tance to the vehicle ahead for a given time
interval.

WARNING

•

Only use a time interval that is suitable in
current traffic conditions.

•

A short time interval gives the driver lim-
ited reaction time if an unexpected situa-
tion occurs in traffic.

In standby mode, the driver will have to regulate
the vehicle's speed and the distance to the vehi-
cle ahead.

When Pilot Assist is in standby mode and your
vehicle comes too close to another vehicle, the
driver will be alerted by the Distance Alert func-
tion.

Standby mode due to action by the driver

Pilot Assist is temporarily deactivated and put in
standby mode if:

•

the brakes are applied

•

The gear selector is moved to N

•

the turn signals are used for more than
1 minute

•

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

A temporary increase in speed, such as when
passing another vehicle, does not affect the Pilot
Assist set speed. The vehicle will return to the set
speed when the accelerator pedal is released.

When the turn signals are used, Pilot Assist's
steering function will be temporarily deactivated.
When this is no longer the case, the steering
function will reactivate if the traffic lane's side
marker lines can still be detected.

Automatic standby mode

Pilot Assist interacts with other systems, such as
Electronic Stability Control. If any of these other

systems are not functioning properly, Pilot Assist
will automatically be deactivated.

WARNING

If this happens, the driver will be alerted by an
audible signal and a message in the instru-
ment panel. The driver will have to adapt the
vehicle's speed, apply the brakes when nec-
essary and keep a safe distance to the vehicle
ahead.

Pilot Assist switches automatically to standby
mode if:

•

the vehicle's speed is below approx. 3 mph
(5 km/h) and Pilot Assist cannot determine if
a vehicle ahead is a stationary vehicle or an
object.

•

the vehicle's speed is below approx. 3 mph
(5 km/h) and the vehicle ahead turns so that
Pilot Assist no longer has a vehicle to follow
(target vehicle).

•

the driver's hands are not on the steering
wheel

•

At certain speeds, Pilot Assist can change target
vehicles and automatically apply the brakes.

Changing target vehicles

If the target vehicle turns suddenly, there may be a sta-
tionary vehicle ahead

When Pilot Assist is actively following another
vehicle at speeds under 20 mph (30 km/h) and
changes targets from a moving vehicle to a sta-
tionary one, the system will brake for the station-
ary vehicle.

WARNING

If Pilot Assist changes targets from a moving
vehicle to a stationary one at speeds above
20 mph (30 km/h), the system will not react
to the stationary vehicle and will accelerate to
the previously set speed.

The driver must actively apply the brakes to
slow/stop the vehicle.

Automatic standby mode when changing
targets

Pilot Assist disengages and goes into standby
mode if:

•

your vehicle's speed goes below approx.
3 mph (5 km/h) and Pilot Assist cannot
determine if the target object is a stationary
vehicle or some other type of object such as
