• Driver Alert Control (p. 362) Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be
reduced in certain situations.
In certain situations, the system may provide a
warning even if it has not detected a change in
driving behavior, e.g.:
• in strong crosswinds
• on grooved road surfaces.
WARNING In certain cases, driving behavior might not be
affected despite the driver's fatigue – when
using the Pilot Assist function – resulting in
the driver not getting a warning from DAC.
It is therefore very important to always stop
and take a break at the slightest sign of fati-
gue, regardless of whether the DAC function
has issued a warning or not.
NOTE
The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

Driver Alert Control (p. 362) Lane Keeping Aid
Lane Keeping Aid (LKA 107
) is designed to
actively steer the vehicle on freeways, highways
and other major roads to help the driver reduce
the risk of the vehicle unintentionally veering out
of the lane.
Lake Keeping Assistance steers the vehicle back
into the lane and/or alerts the driver using vibra-
tions in the steering wheel.
Lane Keeping Aid is active at speeds between
65-200 km/h (40-125 mph) on roads with
clearly visible traffic lane marker lines.
On narrow roads, the function may be unavailable
and go into standby mode. The function will
become available again when the road becomes
sufficiently wide. A camera monitors the road/traffic lane's marker lines.

HYBRID INFORMATION
406General information about Twin
Engine
Twin Engine vehicles are driven just like any
other vehicle, but certain functions differ from a
vehicle powered exclusively by gasoline. The
electric motor powers the vehicle primarily at low
speeds; the gasoline engine is used at higher
speeds or during more active driving. The instrument panel displays Twin Engine-spe-
cific information - charging information, selected
drive mode, distance to discharged battery and
hybrid battery charge level.
Different drive modes can be selected while driv-
ing, e.g. electric power only or, if more power is
needed, a combination of electric and gasoline
power. The vehicle calculates the optimal combi-
nation of driveability, driving experience, environ-
mental impact and fuel economy for the selected
drive mode.
In order to function optimally, the hybrid battery
(and its electrical drive systems) and the gasoline
engine (and its drive systems) must be at the
correct operating temperature. Battery capacity
can be considerably reduced if the battery is too
cold or too hot. Preconditioning prepares the
vehicle's drive systems and passenger compart-
ment before driving to help reduce both wear and
energy consumption. It also helps increase the
hybrid battery's range.
The hybrid battery, which powers the electric
motor, is recharged using the charging cable. It
can also be recharged during light braking and through engine braking in gear position B. The
combustion engine can also help recharge the
hybrid battery.
Important
No electrical current
Keep in mind that if there is no electrical current
to the vehicle, i.e. the ignition is switched off or
the start battery is discharged, certain functions
such as brakes, power steering, etc. will not work.
WARNING If the vehicle does not have electrical current
and both the electric motor and the gasoline
engine are switched off, the brakes cannot be
used to stop the vehicle.
Towing not permitted
Never tow a Twin Engine vehicle behind another
vehicle, as this could damage the electric motor.
Exterior engine noise
WARNING
Keep in mind that the vehicle does not emit
any engine noise when using the electric
motor and may therefore be difficult to detect
for children, pedestrians, cyclists or animals.
This is especially true at low speeds, e.g. in
parking lots.
High-voltage electrical current
WARNING Several components in the vehicle work with
high voltage that can be hazardous in case of
an incorrect procedure. These components
and any orange wiring in the vehicle may only
be handled by trained and qualified Volvo
service technicians.
Do not touch anything that is not clearly descri-
bed in this Owner's Manual.

• Long-term storage of vehicles with hybrid
batteries (p. 421) Charging current
Charging current is used to charge the hybrid
battery and precondition the vehicle. Charging is
performed by connecting a charging cable
between the vehicle's charging socket and a
120/240 V electrical socket (alternating cur-
rent).
When the charging cable is activated, a message
will be displayed in the instrument panel and an
indicator light in the vehicle's charging socket will
illuminate. Charging current is primarily used for
battery charging, but is also used for precondi-
tioning. The vehicle's start battery is charged
along with the hybrid battery.
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.
NOTE •
In extremely cold or hot weather, part of
the charging current is used to heat/cool
the hybrid battery and the passenger
compartment, resulting in a longer charg-
ing time.
• The charging time is longer if precondi-
tioning has been selected. The time
required depends primarily on the ambi-
ent temperature. There are normally several 120/240 V power
consumers in one fuse circuit, which means that
more than one power consumer (e.g. lighting,
vacuum cleaner, electric drill, etc.) may use the
same fuse.

STARTING AND DRIVING
}}
425
In some situations, such as in cold weather or if
the hybrid battery's charge level is too low, the
gasoline engine will start instead.
The vehicle should not be started with the charg-
ing cable connected. However, if the cable can-
not be pulled out or if the vehicle incorrectly
detects a cable that is not connected, the vehicle
can be started using an override procedure:
1.

Press the brake pedal and turn the start
knob clockwise.
2. Charge cable Remove before start will
appear in the instrument panel.
3.

Turn the start knob clockwise again.
4. Removed? Turn and hold start knob 7s
will appear. Turn the knob clockwise and hold
it for 7 seconds to start the vehicle. Location of the backup reader in the tunnel console. If the
Vehicle key not found message is shown
in the instrument panel at start, place the remote
key at the backup reader and then make a new
start attempt.
NOTE When the remote key is placed in the backup
reader, make sure that no other vehicle keys,
metal objects or electronic devices (e.g. cellu-
lar phones, tablets, laptops or chargers) are in
the backup reader. Multiple vehicle keys close
to each other in the backup reader can dis-
rupt their functionality.
If Vehicle start System check, wait is dis-
played in the instrument panel while attempting
to start the vehicle, wait until the message disap-
pears and try again to start the vehicle.
CAUTION If the engine has not responded after 3
attempts – wait for 3 minutes before starting
a new attempt. Starting capability increases if
the starter battery is given time to recover.
NOTE
The vehicle cannot be started if the hybrid
battery is discharged.
WARNING •
Always remove the remote key from the
passenger compartment when you leave
the vehicle and make sure the ignition is
in mode 0.
• Always put the gear selector in P and
apply the parking brake before leaving
the vehicle. Never leave the vehicle unsu-
pervised while the engine is running.
• Always open the garage door fully and
make sure that ventilation is very good
before starting the engine in a garage.
The exhaust fumes produced by the vehi-
cle contain carbon monoxide, which is
invisible and odorless but very toxic.
WARNING Never remove the remote control key from
the vehicle while driving.
WARNING
Always take along the remote control key
when leaving the vehicle and make sure that
the vehicle electrical system is in ignition
