MAINTENANCE AND SERVICE
578If the engine oil is not checked regularly and the level becomes low, this could cause seriousengine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filledwith a specially adapted synthetic engine oil.Great care has been put into the choice of oil,with consideration given to service life, starta-bility, fuel consumption and environmentalimpact. For the recommended service intervals to apply, an approved engine oil must be used.Only use the prescribed oil grade to top off orchange the oil. Otherwise, there is a risk ofthe vehicle's service life, startability, fuel con-sumption and environmental impact beingaffected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low. Onengine variants with an oil pressure sensor, a
warning symbol is displayed in the instrument panel when oil pressure is low
. On engine
variants with an oil level sensor, the
warn-
ing symbol in the instrument panel and display messages are used to alert the driver. Someengine variants have both systems. Contact aVolvo retailer for more information. Change the engine oil and oil filter according to the schedule specified in the Warranty and Main-tenance Records Information booklet. Oils of ahigher grade than that specified may be used. Ifthe vehicle is driven in adverse conditions, Volvorecommends using an oil with a higher gradethan that specified.

Automatic car washes The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easier toclean because dirt does not attach as strongly. Italso reduces the risk of scratches and keeps thevehicle looking new.
Automatic car washesAn automatic car wash is a fast and easy way to keep your vehicle clean, but it does not reach allareas of the vehicle. For best results, Volvo rec-ommends hand washing your vehicle or supple-menting automatic car washes with a hand wash.
NOTE
Volvo recommends not washing the vehicle in an automatic car wash during the first fewmonths; the paintwork on new vehicles takessome time to fully harden.
CAUTION
Before driving the vehicle into a car wash, deactivate the Automatic Braking when Sta-tionary and Automatic Parking Brake Applica-tion functions. If the functions are not deacti-vated, the brake system will seize when thevehicle is stationary and the vehicle will not beable to roll.
CAUTION
For automatic car washes in which the vehicle is pulled forward on rolling wheels:
1. Before washing the vehicle, make surethat the automatic rain sensor is deacti- vated. If it is not deactivated and inadver-tently starts, the wiper arms could bedamaged.
2. To help prevent damage from the auto- matic car wash machinery, make surethat the door mirrors are folded in, anten-nas retracted or removed, and any auxili-ary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the switch in the tunnel console.
5. Turn off the "Automatic Parking Brake Application" function in the center dis-play's Top view.
6. Turn off the engine by turning the start knob in the tunnel console clockwise.Hold the knob in position for at least2 seconds.
The vehicle is now ready for the automatic carwash.

to the right until the blade loosens from the arm.
3. Press the new wiper blade until it clicks into place. Check to make sure the blade issecurely in place.
