Pilot Assist limitations
Pilot Assist functionality may be reduced in cer-
tain situations.
Pilot Assist is a driver support function designed
to simplify driving and assist the driver in many
situations. However, the driver is always responsi-
ble for maintaining a suitable distance to vehicles
or objects around it and ensuring that the vehicle
is correctly positioned in the traffic lane.
WARNING In some situations, Pilot Assist may have trou-
ble helping the driver properly or may be
deactivated automatically – we advise against
using Pilot Assist in such cases. Examples of
such situations include:
the lane markings are worn, missing or
cross each other.
lane division is unclear, for example, when
the lanes divide or merge or at exits or
when there are multiple sets of markings.
edges or other lines than lane markings
are present on or near the road, e.g.
curbs, joints or repairs to the road sur-
face, edges of barriers, roadside edges or
strong shadows.
the lane is narrow or winding.
the lane contains ridges or holes.
weather conditions are poor, e.g. rain,
snow or fog or slush or reduced visibility
with poor light conditions, backlighting,
wet road surface, etc.
The driver should also note that Pilot Assist
has the following limitations:
High curbs, roadside barriers, temporary
obstacles (traffic cones, safety barriers,
etc.) are not detected. Alternatively, they
may be detected incorrectly as lane mark-
ings, with a subsequent risk of contact
between the vehicle and such obstacles. The driver is responsible for ensuring that
the vehicle maintains a suitable distance
from such obstacles.
The camera and radar sensors do not
have the capacity to detect all oncoming
objects and obstacles in traffic environ-
ments, e.g. potholes, stationary obstacles
or objects that completely or partially
block the route.
Pilot Assist does not "see" pedestrians,
animals, etc.
The recommended steering input is lim-
ited in force, which means that it cannot
always help the driver to steer and keep
the vehicle within the lane.
In vehicles equipped with Sensus
Navigation*, the function is able to use
information from map data, which could
cause variations in performance.
Pilot Assist is switched off if the power
steering is working with reduced power -
e.g. during cooling due to overheating
(see section "Speed-dependent steering
force").
The driver can always correct or adjust steering
assistance provided by Pilot Assist by turning the
steering wheel to the desired position.

DRIVER SUPPORT
376Lane Keeping Aid limitations
In certain demanding driving conditions, Lane
Keeping Aid may not be able to properly assist
the driver. In these situations, it is recommended
that the function be deactivated.
Examples of such situations include:
road work
winter driving conditions
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane's
side markings
when the power steering works at reduced
power, e.g. during cooling due to overheating
(see section “Speed-dependent steering
force”).
NOTE The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

Limitations of Run-Off Mitigation
with steering assistance
In certain demanding driving conditions, the
function may not be able to properly assist the
driver. In these situations, it is recommended
that it is turned off.
Examples of such situations include:
road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane's
side markings
when the power steering works at reduced
power, e.g. during cooling due to overheating
(see section “Speed-dependent steering
force”).
NOTE The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

risks from oncoming traffic
This sub-function can help assist a distracted
driver who has not noticed that the vehicle is
veering into oncoming traffic. The function provides assistance by swerving your vehi-
cle back into your own lane.
Oncoming vehicles
Own vehicle
The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly
visible traffic lane markings/lines.
If your vehicle is starting to veer from your own
lane and a vehicle is approaching from the oppo-
site direction, this function can help the driver
steer the vehicle back into its own lane.

Towing using a towline (p. 487) Charging the hybrid battery
In addition to the conventional fuel tank, your
vehicle is also equipped with a rechargeable
lithium-ion hybrid battery.
WARNING California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To mini-
mize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, serv-
ice your vehicle in a well ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more infor-
mation go to www.P65Warnings.ca.gov/
passenger-vehicle.
The hybrid battery can be recharged using the
charging cable stored in a storage space in the
cargo compartment.
WARNING The hybrid electrical system in your vehicle
uses high voltage electrical current. Any dam-
age to this system or to the hybrid battery
may result in the danger of overheating, fire,
or serious injury. If the vehicle is involved in a
collision or subjected to flooding, fire, etc.,
have it inspected by a trained and qualified
Volvo service technician. Prior to this inspec-
tion, the vehicle should be parked outdoors at
a safe distance from any building or poten-
tially flammable materials.
The hybrid battery's charging time depends on
the charging current used.
NOTE The capacity of the hybrid battery diminishes
somewhat with age and use, which could
result in increased use of the gasoline engine
and consequently, slightly higher fuel con-
sumption.
WARNING
If the hybrid battery needs to be replaced, this
may only be done by a Volvo retailer or
authorized Volvo workshop.

WARNING

The charging cable must be grounded
when in use. It is equipped with a cord
with a grounding conductor and a
grounding plug. The plug must be
inserted into an appropriate outlet that is
properly installed and grounded in
accordance with all local codes and ordi-
nances and is not damaged in any way.
Children should be supervised when in
the vicinity of the charging cable when it
is plugged in.
High voltage is present in your electric
meter housing and power distribution
service panel. Contact with high voltage
can cause death or serious personal
injury.
Do not use the charging cable if it is
damaged in any way. A damaged or mal-
functioning charging cable may only be
repaired by a workshop – an authorized
Volvo workshop is recommended.
Always position the charging cable so
that it will not be driven over, stepped on,
tripped over or otherwise damaged, or
cause personal injury.
Disconnect the charger from the wall out-
let before cleaning it.
Never connect the charging cable to an
extension cord or a multiple plug socket.
Also, refer to the manufacturer's instructions
for using the charging cable and its compo-
nents.
CAUTION Power strips, extension cords, surge protec-
tors or similar devices must not be used
together with the charging cable since this
may involve a risk of fire, electric shocks, etc.
An adapter may not be used between the
120/240 V outlet (AC, alternating current)
and the charging cable.
CAUTION
Never detach the charging cable from the
120/240 V outlet (AC, alternating current)
while charging is in progress – the
120/240 V outlet could be damaged in such
circumstances. Always interrupt charging first
and then disconnect the charging cable – first
from the vehicle's charging socket and then
from the 120/240 V outlet.
CAUTION Wipe the charging cable with a clean cloth
lightly moistened with water or a mild deter-
gent. Do not use chemicals or solvents.
The charging cable and its components must
not be rinsed or immersed in water.

device
The charging cable has a circuit breaker that
helps protect against current overloads and ther-
mal overheating.
WARNING Charging the hybrid battery may only be done
from approved, grounded 120/240 V outlets
(AC, alternating current). If the electrical cir-
cuit or electrical socket's capacity is not
known, let a licensed electrician inspect the
electrical circuit's capacity. Using a charge
level that exceeds the electrical circuit's or
electrical outlet's capacity may start a fire or
damage the electrical circuit.
WARNING
The charging cable's residual current
breaker helps protect the vehicle's charg-
ing system but cannot ensure that an cur-
rent overload will never occur.
Never use visibly worn or damaged elec-
trical sockets. Doing so could lead to fires
or serious injury.
Never connect the charging cable to an
extension cord.
Maintenance or replacement of the hybrid
battery may only be performed by a
trained and qualified Volvo service techni-
cian.
If the charging cable's residual current device is
triggered, the blue indicator light in the charging
module will not illuminate when the charging
cable is plugged into an electrical outlet (or the
red warning light will glow steadily). Have the out-
let checked by a licensed electrician or try using
another wall outlet.
