CLIMATE CONTROL
* Option/accessory.
230 Parking climate
The passenger compartment climate can be pre-
conditioned or maintained when the vehicle is
parked. For full functionality, the vehicle's charg-
ing cable must be plugged in. Preconditioning and the climate comfort retaining func-
tion are controlled from the Parking climate tab in the
center display's Climate view.

(p. 236) Preconditioning
Preconditioning the vehicle before driving can
help reduce wear and reduce energy consump-
tion during a trip.
Preconditioning can be started immediately or
started at a preset time using a timer.
The function utilizes several of the vehicle's sys-
tems:
• In cold weather, the high-voltage coolant
heater (HVCH) heats the passenger com-
partment to a comfortable temperature.
• In warm weather, air conditioning cools the
passenger compartment to a comfortable
temperature.
• The electrically heated steering wheel* and
seats* can be activated.
• Heating for the windshield, rear window and
door mirrors are automatically activated as
needed.
During preconditioning in a hot climate, conden-
sation from the air conditions may drip under the
vehicle. This is normal.

STARTING AND DRIVING

•
Speed limiter (p. 278)
• 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.

STARTING AND DRIVING
* Option/accessory.
468 Overheating of engine and
transmission
In demanding driving conditions, such as driving
in mountainous areas or hot weather, there is a
risk of the engine or transmission overheating,
especially when carrying heavy loads.
• Engine power may be temporarily limited.
• Remove any auxiliary lights mounted in front
of the grille when driving in hot weather.
• If the temperature in the engine's cooling
system becomes too high, a warning symbol
will appear in the instrument panel along with
the message Engine temperature High
temperature Stop safely. Pull over to a safe location and let the engine idle for a few
minutes to cool down.
• If the message
Engine temperature High
temperature Turn off engine or Engine
coolant Level low, turn off engine is dis- played, stop the vehicle and turn off the
engine.
• If the transmission begins to overheat, an
alternative gear shifting program will be
selected. An integrated protective function
will also be activated, the warning symbol will
illuminate and the message Transmission
warm
Reduce speed to lower
temperature or Transmission hot Stop
safely, wait for cooling will be displayed in the instrument panel. Follow the recommen-
dations given by reducing speed or stopping the vehicle safely and letting the engine idle
for a few minutes to let the transmission
cool.
• If the vehicle begins to overheat, the air con-
ditioning may be temporarily switched off.
• After a prolonged period of driving in
demanding conditions, do not turn off the
engine immediately after stopping.
NOTE It is normal for the engine's cooling fan to
operate for a short time after the engine is
switched off.

||MAINTENANCE AND SERVICE
600
Monthly:
•
Check cold tire pressure in all tires. Inspect
the tires for wear.
• Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
• Clean interior glass surfaces with a glass
cleaner and soft paper towels.
• Wipe driver information displays with a soft
cloth.
• Visually inspect battery terminals for corro-
sion. Corrosion may indicate a loose terminal
connector, or a battery near the end of its
useful service life. Consult your Volvo retailer
for additional information.
As needed:
Wash the car, including the undercarriage, to
reduce wear that can be caused by a buildup of
dirt, and corrosion that can be caused by salt res-
idues.
Clean leaves and twigs from air intake vents at
the base of the windshield, and from other places
where they may collect.
NOTE Complete service information for qualified
technicians is available online for purchase or
subscription at www.volvotechinfo.com.

workshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net-
work for secure data transfer between your vehi-
cle and the workshop. Your visit to the workshop
will be easier and more effective when diagnos-
tics information and software can be transferred
over the workshop's network.
When you arrive at the workshop, your technician
can connect your vehicle to the workshop's Wi-Fi
network to perform troubleshooting and down-
load software. For this type of communication,
the vehicle only connects to the workshop's net-
work. The vehicle can only be connected to the
designated workshop networks, not to any other
network, e.g. your home network.
Manual connection to workshop Wi-FiManual connection is usually performed by a
service technician. Because the technician uses
the buttons on your remote key to connect the
vehicle, it is important that you bring a key with
buttons when taking the vehicle in to a workshop.
Pressing the lock button on the remote key three
times will connect the vehicle to the workshop's
Wi-Fi network.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.
