Parking brake malfunctions
If it has not been possible to apply or release the parking brake after several attempts, consult atrained and authorized Volvo service technicianor retailer.
An audible signal will sound if the parking brake is applied when the vehicle is being driven. If thevehicle must be parked while the parking brake isnot functioning properly: • Put the gear selector in
P.
• If the vehicle is pointing
uphill, turn the front
wheels so that they point away from the curb.
• If the vehicle is pointing
downhill, turn the
front wheels so that they point toward the curb.
• Put the gear selector in
P.
Low battery charge levelIf the battery is discharged, the parking brakecannot be operated. Connect an auxiliary batteryto the vehicle.
Replacing brake padsThe rear brake pads have to be replaced by atrained and authorized Volvo service techniciandue to the design of the electric parking brake.

Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and thatfuel consumption and the oil level are normal.
• Check for fuel, oil, and fluid leakage.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (including the sparetire where applicable), and replace those thatare worn. Also, check tire inflation pressure.
• The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to drive

Selecting sub-channels
To listen to a station's sub-channel(s), tap the station on the screen or press the forward/backarrow keys on the right-side steering wheel key-pad or below the screen. Sub-channels can also be stored as favorites, see the article "Changing and searching for radio sta-tions". If you tap a sub-channel favorite, it may take up to 6 seconds before the channel becomes audi-
ble. If you tap a station while you are out of digital range of the transmitter,
No reception will be
displayed.

HD Radio limitations
Limitations
•
Main channel vs. sub-channels (FM only)
:
The main channel is the only channel that can receive in hybrid mode (both digital andanalogue). If a frequency has sub-channels,they are broadcast in digital mode only. Themain FM channel will be displayed as, forexample, "WRIF-FM HD1". The sub-FMchannels will be displayed as"WRIF-FMHD2", "WRIF-FM HD3", etc.
• Reception coverage area
: Due to current
IBOC transmitter power limitations, thereception coverage area in digital mode issomewhat more limited than the station'sanalogue coverage area. Please be awarethat as with any radio broadcast technology,terrain, time of day, foliage level and buildinglocation can have positive or negative effectson radio reception.
• Analogue to digital/digital to analogueblending
: Analogue to digital blending will
occur as the signal strength reaches a presetthreshold in the receiver. This will be noticea-ble in fringe areas (areas with weak recep-tion) and is normal.
NOTE
There may be a noticeable difference in sound quality when a change from analogueto digital or digital to analogue occurs, suchas:
• Volume increase or decrease
• Equalizer settings, i.e., Bass/ Midrange/Treble cut or boost
• Time alignment (Digital program materialin extreme cases can be as much as 8seconds behind the analogue). This willnoticeable as a "stuttering" effect.
The above items are dependant on thebroadcaster's equipment settings and donot indicate a fault in the vehicle's radioreceiver or antenna systems .

WHEELS AND TIRES

sidewall (see the illustration). A tire with e.g., visi- ble cracks or discoloration should be replacedimmediately.
Tire economy
•
Maintain correct tire pressure.
• Avoid fast starts, hard braking and tirescreeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very impor-tant.
• Unbalanced wheels impair tire economy anddriving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with the mosttread should be mounted on the rear wheelsto reduce the chance of oversteer duringhard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.
Tire rotationYour vehicle has no required tire rotation. Tirewear is affected by a number of factors such astire inflation, ambient temperature, driving style,etc.
NOTE
•If the tires are rotated, they should only be moved from front to rear or vice versa.They should never be rotated left toright/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000 miles(5,000 km) and thereafter at 6,000-mile(10,000-km) intervals. Some customersfind that tire rotation may help to getextra mileage from tire life.
• Tire rotation should only be performed iffront/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).
Storing wheels and tiresWhen storing complete wheels (tires mounted on rims), they should be suspended off the floor orplaced on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not besuspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be stored inclose proximity to solvents, gasoline, oils, etc.
WARNING
• The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unapprovedwheel/tire size combinations can nega-tively affect your vehicle's stability andhandling.
• Any damage caused by installation ofunapproved wheel/tire size combinationswill not be covered by your new vehiclewarranty. Volvo assumes no responsibilityfor death, injury, or expenses that mayresult from such installations.
