CAUTION Avoid activating the washer system when it is
frozen or the fluid reservoir is empty. Other-
wise, there is a risk of damaging the pump.

High temperaturesIf the temperature in the passenger compartment
is very high, the camera/radar sensor will switch
off temporarily for approx. 15 minutes after the
engine is started to protect its electronic compo-
nents. When the temperature has cooled suffi-
ciently, the camera/radar sensor will automati-
cally restart.Damaged windshield
CAUTIONIf there are cracks, scratches or stone chips
on the windshield in front of any of the cam-
era and radar unit "windows" and this covers
an area of about 0.5 × 3.0 mm
(0.02 × 0.12 in.) or more, contact a workshop
to have the windshield replaced – an author-
ized Volvo workshop is recommended.
Failure to take action could result in reduced
performance for the driver support systems
that use the camera and radar unit.
It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.
To avoid the risk of loss of function, malfunc-
tion or reduced function of the driver support
systems that use the radar unit, the following
also apply:
• Volvo advises against repairing cracks,
scratches or stone chips in the area in
front of the camera and radar unit – the
entire windshield should instead be
replaced.
• Before replacing the windshield, contact
an authorized Volvo workshop to verify
that the right windshield has been
ordered and installed. •
The same type of windshield wipers or
wipers approved by Volvo should be used
for replacement.
CAUTION If the windshield is replaced, the camera and
radar unit must be recalibrated by a workshop
to help ensure proper functioning of all of the
vehicle's camera and radar-based systems –
an authorized Volvo workshop is recom-
mended.

• Selecting ignition mode (p. 428) Ignition modes
The vehicle's ignition can be put in various
modes (levels) to make different functions availa-
ble.
To enable the use of a limited number of func-
tions when the engine is not running, the ignition
can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual.
The following table shows which functions are
available in each ignition mode: Mode
Functions
0 •The odometer, clock and tem-
perature gauge are illuminated A
.
• The power seats* can be
adjusted.
• The power windows can be used.
• The center display is activated
and can be used A
.
• The 12 V outlet in the cargo com-
partment* can be used.
• The infotainment system can be
used A
.
In this ignition mode, the functions are
available for a limited time and then
switch off automatically.
I •The panoramic roof, power win-
dows, 12 V outlet in passenger
compartment, Bluetooth, naviga-
tion, phone, blower and wind-
shield wipers can be used.
• The power seats can be adjusted.
• The 12 V outlet in the cargo com-
partment can be used.
Electrical current will be taken
from the battery in this ignition
mode.

• Tire sealing system (p. 572) Winter driving
It is important to check the vehicle before driving
in cold/snowy conditions to make sure it can be
driven safely.
Before the cold season arrives:• Make sure the engine coolant contains 50%
antifreeze. This mixture helps protect the
engine from frost erosion down to
approx. -35 °C (-31 °F). Do not mix different
types of antifreeze as this could pose a
health risk.
• Keep the fuel tank well filled to prevent con-
densation from forming.
• Check the viscosity of the engine oil. Oil with
low viscosity (thinner oil) improves cold-
weather starting and reduces fuel consump-
tion when driving with a cold engine.
CAUTION Low-viscosity oil should not be used with hard
driving or in hot weather.
•
Check the condition and charge level of the
start battery. Cold weather places greater
demands on the start battery and reduces its
capacity.
• Use washer fluid containing antifreeze to
help prevent ice from forming in the washer
fluid reservoir.
Slippery driving conditionsFor optimal traction and roadholding, Volvo rec-
ommends using snow tires on all wheels when-
ever there is a risk of snow or ice on the road.
NOTE Certain countries require use of winter tires
by law. Not all countries permit the use of
studded tires.
Practice driving on slippery surfaces under con-
trolled conditions to learn how the vehicle reacts.

Battery drain
The electrical functions in the vehicle drain the
battery to varying degrees. Avoid using ignition
mode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain
power from the electrical system. Do not use
functions that use a lot of electrical current when
the engine is turned off. Examples of such func-
tions are: • blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message is
shown in the driver display. The vehicle's energy-
saving function will then turn off or reduce certain
functions, such as the blower and/or the audio
system.
– Charge the battery by starting the engine
and let it run for at least 15 minutes (driving
charges the battery faster than letting the
engine idle).

• Ignition modes (p. 427) Jump starting using another battery
If the start battery is discharged, current from
another battery can be used to start the vehicle. Jumper cable connecting points.
CAUTION
The charging point of the vehicle is only
intended for jump starting the vehicle in ques-
tion. The charging point is not intended for
jump-starting another vehicle. Using the
charging point to start another vehicle could
cause a fuse to blow, which would cause the
charging point to stop working.
If a fuse has blown, 12 V Battery Fuse failure
Service required will be displayed in the instru-
ment panel. Volvo recommends contacting an
authorized Volvo workshop. To avoid short circuits or other damage, the fol-
lowing steps are recommended when jump star-
ting the battery:
