CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.

Tire Pressure Monitoring System (TPMS) TPMS provides a warning if inflation pressure in one or more tires is too low. It also uses a sym-bol (called a telltale) that will flash for60 seconds and then glow steadily if there is asystem malfunction.
TPMS uses the rotational speed of the tires in combination with signal analysis of the ABS sen-sor signals to determine if they are properly infla-ted. When a tire is under-inflated, its diameter(and consequently also its rotational speed)changes. By comparing the individual tires witheach other it is possible to determine if one ormore tires are under inflated. If inflation pressureis too low, an indicator symbol will illuminate inthe instrument panel and a text message will bedisplayed.
Symbol
Explanation
The symbol illuminates to indicate low tire inflation pressure. If a malfunction occurs in the sys- tem, the tire pressure warning sym-bol will flash for approximately1 minute and then remain illumi-nated.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehi-cle manufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tiresof a different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflation pres-sure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure telltale.

PRACTICAL INFORMATION
104When the system detects a malfunction, the tell- tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panel
When the TPMS symbol illuminates, the following text messages may also be displayed:
•
Tire pressure low Check tires, calibrate
after fill
•Tire pressure system Temporarily
unavailable
•Tire pressure system Service required
If TPMS cannot determine which tire(s) have low inflation pressure:
• All four tires will be shown as affected in thecenter display After changing wheels, always calibrate the sys-tem to avoid false warnings. TPMS does not replace the need for regular tire inspection and maintenance.
NOTE
If you change to tires with a different dimen- sion than the factory-installed ones, theTPMS system must be calibrated for thesetires. TPMS cannot be turned off.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

Checking tire inflation pressure
The Tire Pressure Monitoring System (TPMS) makes it possible to view the current inflationpressure status of all four tires.
Checking inflation pressure
1. Open the Car status app in the center dis-
play's Application view.
2. Tap
TPMS to see the tires' current inflation
pressure status.
The on-screen graphic displays the inflation pres- sure status.

Status view. The illustration is generic and may vary from model to model or after a software update
Color indications: Green: tire pressure is above the threshold for a
low inflation pressure warning. Yellow : low tire pressure.
• One yellow wheel: the tire indicated is under- inflated.
• All wheels yellow: two or more tires areunder-inflated.
Stop safely and check/re-inflate the tire(s) assoon as possible. Calibrate TPMS after re-inflat-ing the tire(s). All wheels gray:
• Calibration is underway
• Inflation pressure status is not known It might be necessary to drive at a speed of at least 22 mph (35 km/h) for several minutes forthe system to become operational. All wheels gray combined with the message
Tire pressure system Temporarily
unavailable and the TPMS symbol in the
instrument panel (
) remains illuminated
after flashing for 1 minute : the system is tem-
porarily unavailable. It should become operational again shortly. All wheels gray combined with the message
Tire pressure system Service required and
the TPMS symbol in the instrument panel (
) remains illuminated after flashing for
1 minute : the system is not functioning correctly.
Have it checked by a trained and qualified Volvo service technician.

Reinflating tires equipped with the Tire Pressure Monitoring System(TPMS) When low tire pressure has been detected, a message will be displayed in the instrumentpanel and the Tire Pressure Monitoring Systemsymbol will illuminate.
Symbol
Explanation
When the TPMS symbol illuminates and a message is displayed, check,reinflate the tire(s) and calibrateTPMS.
1. Use a tire pressure gauge to check the infla-
tion pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure. Consult the tire pressure decal located on the driver's side B-pillar (the structural mem-ber at the side of the vehicle, at the rear ofthe driver's door opening) or the inflationpressure table in your printed owner's man-ual supplement.
3. Calibrate the Tire Pressure Monitoring System, see the article "Calibrating the TirePressure Monitoring System".

The wipers will also leave the service position if:
• The wipers are activated.
• The windshield washers are activated.
• The rain sensor is activated.
CAUTION
If the wiper arms have been folded out from the windshield while in the service position,fold them back against the windshield beforereturning the wipers to the normal position tohelp avoid scratching the paint on the hood.

Refilling the windshield washer fluid reservoir
Washer fluid helps keep the windshield and headlights clean.
The windshield and headlight washers * share a
common reservoir. Open the blue cap to refill washer fluid (see the illustration for the locationof the reservoir). During cold weather, the reservoir should be filled with windshield washer solvent containing anti-freeze. Use Volvo Original Washer Fluid or theequivalent with a recommended pH valuebetween 6 and 8 in a 1:1 solution. When there is approx. 1 qt (1 liter) of washer fluid remaining in the reservoir, a text message and the
symbol will be displayed in the
instrument panel.
