All tires gray:
Calibration in progress.
Status unknown.
The vehicle may need to be driven for a fewminutes at a speed above 35 km/h (22 mph) toactivate the system.
All tires gray and a message:
Tire pressure system Temporarilyunavailable. The indicator symbol will flashfor about 1 minute and then glow steadily.The system is temporarily unavailable and willbe activated momentarily.
Tire pressure system Service required.The indicator symbol will flash for about 1minute and then glow steadily. If the systemis not working properly, contact a work-
shop12.

Action when warned of low tirepressure
When the system for monitoring inflation pres-
sure 13 detects low inflation pressure in a tire,immediate action is required.
If the system's indicator symbol illumi-nates and the message Tire pressurelow is displayed, check the tire pres-sure and inflate if necessary.
1. Switch off the ignition.
2. Check the inflation pressure on all four tiresusing a tire pressure gauge.
3.Inflate the tire to the correct inflation pres-sure; see the tire pressure placard on thedriver's side B pillar for recommended pres-sures for factory-mounted tires.
4. Through calibration of the system via thecenter display after the tire pressure hasbeen adjusted.
Please be aware that the indicator symbolwill not go out until the low tire pressure hasbeen corrected and the system has beenrecalibrated.
NOTE
To help prevent incorrect inflation pressure,pressure should be checked when the tiresare cold. The tires are considered to be coldwhen they have reached the same tempera-ture as the ambient temperature (about 3hours after the vehicle was last driven). Afterdriving for a few kilometers, the tires will warmup and the pressure will increase.

NOTE
After inflating a tire, always replace thevalve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.

WARNING
Incorrect inflation pressure could lead totire failure, which could cause the driverto lose control of the vehicle.
The system cannot predict sudden tiredamage.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.576
12 V outlet in the tunnel console, rear seat.
12 V outlet in trunk/cargo compartment*.

Using the electrical outlets (p. 576)
Using the electrical outlets
The 12 V outlet can be used for devicesintended for this such as MP3 players, coolersand cellular phones.
The ignition must be in at least mode I for theoutlets to supply current. The outlets will then beactive as long as there is sufficient charge in thestart battery.
If the engine is turned off and the vehicle islocked, the outlets will be deactivated. If theengine is turned off and the vehicle remainsunlocked, the sockets will remain active for up to7 minutes.
NOTE
Bear in mind that using the electrical outletswhen the engine is off could cause the starterbattery to have too low of a charge level,which could limit other functionality.
Accessories connected to the electrical out-lets can be activated even when the vehicleelectrical system is off or if preconditioning isused. For this reason, disconnect plugs whenthey are not in use to prevent the starter bat-tery from becoming discharged.
WARNING
Do not use accessories with large orheavy plugs – they could damage the out-let or come loose while you are driving.
Do not use accessories that could causedisruptions to e.g. the vehicle's radioreceiver or electrical system.
Position the accessory so that there is norisk of it injuring the driver or passengersin the event of heavy braking or a colli-sion.
Pay attention to connected accessoriesas they can generate heat that could burnpassengers or the interior.

Using 12 V outlets
1. Remove the stopper (tunnel console) or folddown the cover (trunk/cargo compartment)over the socket and plug in the device.
2. Unplug the device and put the stopper backin (tunnel console) or fold up the cover(trunk/cargo compartment) when the socketis not in use or left unattended.

CAUTION
The maximum power is 120 W (10 A) peroutlet.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.578
The illustration is generic – the design may vary.
To lock the glove compartment:
Insert the key into the lock on the glove com-partment.
Turn the key 90 degrees clockwise.
Remove the key from the lock.
–To unlock, perform the above steps inreverse.

Using the glove box as a cooled area
The glove compartment can be used to cool e.g.drinks or food. Cooling is possible when the cli-mate system is active (i.e. when the ignition is inmode II or when the engine is running).
The illustration is generic – the design may vary.
Activate cooling
Deactivate cooling
–Activate or deactivate cooling by moving thecontrol as far as possible toward the passen-ger compartment/glove compartment.

Sun visors
In the ceiling in front of the driver and front pas-senger, there are sun visors that can be loweredand angled to the side as necessary.
The illustration is generic – the design may vary.
The mirror lighting* comes on automatically whenthe cover is lifted up.
The mirror frame has a holder for e.g. cards ortickets.

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.
