MAINTENANCE AND SERVICE
610

Monthly:
Check cold tire pressure in all tires. Inspectthe 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, toreduce 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 atthe 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 servicetechnician can connect your vehicle to the work-shop's Wi-Fi network to perform troubleshootingand download software. For this type of commu-nication, the vehicle only connects to a work-shop's network. It is not possible to connect thevehicle to another Wi-Fi network (e.g. your homenetwork) in the same way as to a workshop's net-work.

Connecting with remote key
Connection is usually managed by the servicetechnician, who will use the remote key buttons. Itis therefore important to bring a key with buttonswith you when you visit the workshop. Pressingthe lock button on the remote key three times willconnect the vehicle to the workshop's Wi-Fi net-work.
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 withhigh voltage that can be hazardous in case ofan incorrect procedure.
Do not touch anything that is not clearlydescribed 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.
Coolant expansion tank
Brake fluid reservoir (located on the driver'sside)
Washer fluid filler pipe12
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located atthe 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 highand dangerous voltages. The vehicle electricalsystem should always be in ignition mode 0when work in being performed in the enginecompartment.
Do not touch any spark plugs or ignition coilswhen the vehicle electrical system is in igni-tion mode II or when the engine is warm.

NOTE
If the conditions for measuring oil level arenot 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 doesnot mean that anything is wrong in the vehi-cle systems.

Refilling coolant
Coolant helps keep the combustion engine atthe 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 onthe 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 fromthe 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 unscrewthe cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.

MAINTENANCE AND SERVICE
* Option/accessory.624
Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fillcoolant as needed. The level should notexceed the yellow MAX mark inside theexpansion tank.
Put the components back in place in the reverseorder.

CAUTION
Do not ingest the contents. May causedamage to organs (kidneys).
Use premixed coolant according to Vol-vo's recommendations. If concentratedcoolant is used, make sure that the cool-ant mixture is 50% coolant and 50%water of acceptable quality.
Do not mix different types of coolant.
To help ensure sufficient corrosion pro-tection in the system, only use new cool-ant when replacing larger components inthe cooling system.
Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

Replacing bulbs
Halogen headlights are not available on all mod-els and markets. Contact a Volvo retailer formore information.
LED14 bulbs must be replaced by a workshop.An authorized Volvo workshop is recommended.

NOTE
For information on lights not mentioned inthis article, contact a Volvo dealer or a certi-fied Volvo service technician.

NOTE
Exterior lighting such as headlights and tail-lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.

NOTE
Bulbs for active curve lighting* contain tracesof mercury and should therefore always besubmitted to a certified Volvo service techni-cian.

Hybrid battery
The vehicle's electric motor is powered by arechargeable, maintenance-free, lithium-ionhybrid battery.

NOTE
The vehicle cannot be started if the hybridbattery is discharged.

NOTE
If both the starter battery and the hybrid bat-tery are discharged, both batteries must becharged. In such cases, it is not possible tocharge only the hybrid battery first.
The starter battery must have a certain levelof charge for it to be possible to charge thehybrid battery.

WARNING
Hybrid battery replacement may only be per-formed by a workshop – an authorized Volvoworkshop is recommended.

Coolant
The hybrid battery's cooling system has its ownexpansion tank.
CAUTION
Filling the hybrid battery coolant should onlybe performed by a workshop – an authorizedVolvo workshop is recommended.

Specifications for hybrid battery
Type: Lithium-ion
Power reserve: 10.4 kWh.

NOTE
The capacity of the hybrid battery decreaseswith age and use, which could result inincreased use of the combustion engine,leading to higher fuel consumption andreduced electric motor range.
