Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to make sure it can bedriven safely.
Before the cold season arrives:
• Make sure the engine coolant contains 50% antifreeze. This mixture helps protect theengine from frost erosion down toapprox. -35 °C (-31 °F). Do not mix differenttypes of antifreeze as this could pose ahealth risk.
• Keep the fuel tank well filled to prevent con-densation from forming.
• Check the viscosity of the engine oil. Oil withlow 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 greaterdemands on the start battery and reduces itscapacity.
• Use washer fluid containing antifreeze tohelp prevent ice from forming in the washerfluid 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 ofstudded tires.
Practice driving on slippery surfaces under con- trolled conditions to learn how the vehicle reacts.

Overheating of engine andtransmission
In demanding driving conditions, such as driving in mountainous areas or hot weather, there is arisk 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 coolingsystem becomes too high, a warning symbolwill 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

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, analternative gear shifting program will beselected. An integrated protective functionwill also be activated, the warning symbol will illuminate and the message

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 transmissioncool.
• If the vehicle begins to overheat, the air con-ditioning may be temporarily switched off.
• After a prolonged period of driving indemanding conditions, do not turn off theengine immediately after stopping.
NOTE
It is normal for the engine's cooling fan to operate for a short time after the engine isswitched off.

MAINTENANCE AND SERVICE

Monthly:
•Check cold tire pressure in all tires. Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min" and"max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with a softcloth.
• Visually inspect battery terminals for corro-sion. Corrosion may indicate a loose terminalconnector, or a battery near the end of itsuseful service life. Consult your Volvo retailerfor additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup ofdirt, 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 placeswhere they may collect.

Data transfer between vehicle andworkshop 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 workshopwill be easier and more effective when diagnos-tics information and software can be transferredover the workshop's network.
When you arrive at the workshop, your technician can connect your vehicle to the workshop's Wi-Finetwork 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 thedesignated workshop networks, not to any othernetwork, e.g. your home network.
Manual connection to workshop Wi-FiManual connection is usually performed by aservice technician. Because the technician usesthe buttons on your remote key to connect thevehicle, it is important that you bring a key withbuttons when taking the vehicle in to a workshop.Pressing the lock button on the remote key threetimes will connect the vehicle to the workshop'sWi-Fi network. When the car is connected to a Wi-Fi network, the
symbol appears in the center display.

Engine compartment overview
This overview shows some service-related com- ponents.
Some of the components included in the vehi- cle's electric drive system are located in theengine compartment. Exercise caution whenaccessing the engine compartment and onlytouch what is required for normal maintenance.
WARNING
Orange wiring may only be handled by quali- fied personnel.
WARNING
Several components in the vehicle work with high voltage that can be hazardous in case ofan incorrect procedure.
• Do not touch anything that is not clearly described in this Owner's Manual.
• Be careful when checking/filling fluids inthe engine compartment.
The layout of the engine compartment may vary depend- ing on model and engine variant.

Brake fluid reservoir (located on the driver's side)
Washer fluid filler pipe 11
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located at the front of the engine compartment behindthe radiator) may start or continue runningautomatically up to about 6 minutes after theengine is turned off. Always entrust engine washing to a workshop – an authorized Volvo workshop is recom-mended. If the engine is hot, there is a risk offire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicle electrical system should always be in ignition mode
0
when work in being performed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system is in igni- tion mode II or when the engine is warm.

NOTE
If the conditions for measuring oil level are not properly fulfilled (time after engine shut-down, vehicle inclination, ambient tempera- ture, etc.) the message
No value availablewill be shown in the center display. This does not mean that anything is wrong in the vehi-
cle systems.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions on the package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.
