Washing function, right-hand steering wheel lever.
–Move the right-hand steering wheel lever toward the steering wheel to start the wind-shield and headlight washers.
> After the lever is released, the wipers make several extra sweeps.
CAUTION
Avoid activating the washer system when it is frozen or the fluid reservoir is empty. Other-wise, there is a risk of damaging the pump.
Headlight washer *To save washer fluid, the headlights are washed automatically according to a defined intervalwhen the headlights are on.
Reduced washingWhen there is about 1 liter (1 qt) of washer fluid left in the reservoir and the Washer fluid Level
low, refill message is displayed in the instrument
panel together with the
symbol, the washer
fluid supply to the headlights is cut off. This is to prioritize windshield cleaning and visibilitythrough it. The headlights are only washed if highor low beam is on.

High temperaturesIf the temperature in the passenger compartment is very high, the camera/radar sensor will switchoff temporarily for approx. 15 minutes after theengine is started to protect its electronic compo-nents. When the temperature has cooled suffi-ciently, the camera/radar sensor will automati-cally restart.Damaged windshield
CAUTION
If there are cracks, scratches or stone chips on the windshield in front of any of the cam-era and radar unit "windows" and this coversan area of about 0.5 × 3.0 mm(0.02 × 0.12 in.) or more, contact a workshopto have the windshield replaced – an author-ized Volvo workshop is recommended. Failure to take action could result in reduced performance for the driver support systemsthat use the camera and radar unit. It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response. To avoid the risk of loss of function, malfunc- tion or reduced function of the driver supportsystems that use the radar unit, the followingalso apply:
• Volvo advises
against repairing cracks,
scratches or stone chips in the area infront of the camera and radar unit – theentire windshield should instead bereplaced.
• Before replacing the windshield, contactan authorized Volvo workshop to verifythat the right windshield has beenordered and installed.
• The same type of windshield wipers or wipers approved by Volvo should be usedfor replacement.
CAUTION
If the windshield is replaced, the camera and radar unit must be recalibrated by a workshopto help ensure proper functioning of all of thevehicle's camera and radar-based systems –an authorized Volvo workshop is recom-mended.

Ignition modes
The vehicle's ignition can be put in various modes (levels) to make different functions availa-ble.
To enable the use of a limited number of func- tions when the engine is not running, the ignition can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual. The following table shows which functions are available in each ignition mode:
ModeFunctions
0 •The odometer, clock and tem- perature gauge are illuminated A
.
• The power seats
* can be
adjusted.
• The power windows can be used.
• The center display is activatedand can be used A
.
• The 12 V outlet in the trunk
* can
be used.
• The infotainment system can beused A
.
In this ignition mode, the functions are available for a limited time and then switch off automatically.
I •The panoramic roof, power win-dows, 12 V outlet in passengercompartment, Bluetooth, naviga-tion, phone, blower and wind-shield wipers can be used.
• The power seats can be adjusted.
• The 12 V outlet in the cargo com-partment can be used.
Electrical current will be takenfrom the battery in this ignitionmode.ModeFunctions
II •The headlights illuminate.
• Warning/indicator lights illumi- nate for 5 seconds.
• A number of other systems areactivated. However, seat and rearwindow heating can only be acti-vated when the engine is running.
This ignition mode uses a lot ofcurrent from the battery andshould be avoided whenever pos-sible!
A Also activated when the door is opened.

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
• blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Calibrating the compass
The globe is divided into 15 magnetic zones. The compass should be calibrated if the vehicleis driven from one zone to another.
To calibrate the compass:
1. Stop the vehicle in a large, open area away from steel constructions and high-voltage power lines.
2. Start the engine and switch off all electrical equipment (climate system, wipers, etc.) andmake sure all doors are closed.
NOTE
Calibration may fail or not even be initiated if electrical equipment is not turned off.
3. Hold the button on the bottom of the rear-view mirror pressed for about 3 seconds (using e.g. a paper clip). The number of thecurrent magnetic zone is shown.

Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can thenread "faults." In some states, this type of inspec-tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons:
• If your Check Engine (MIL) light is lit, yourvehicle may fail inspection.
• If your vehicle's Check Engine light was lit,but went out without any action on your part,OBD II will still have a recorded fault. Yourvehicle may pass or fail, depending on theinspection practices in your area.
• If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit - or was lit but went out without service, have your vehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, a periodof driving is necessary to bring the OBD IIsystem to "ready" for inspection. Two half-hour trips of mixed stop-and-go/highwaydriving are typically needed to allow OBD II toreach readiness. Your Volvo retailer can pro-vide you with more information on planning atrip.
• Maintain your vehicle in accordance with yourvehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet. The following points can be carried out between the normally scheduled maintenance services.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
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.
