Park Assist Pilot*
Park Assist Pilot (PAP117) helps the driver pullinto and out of parking spaces.
PAP first checks whether thereis sufficient space and thensteers the car into the space.
The center display uses sym-bols, graphics and messages toinform the driver of what stepsneed to be taken and when.

WARNING
The PAP function is supplementary driversupport intended to facilitate driving andhelp make it safer – it cannot handle allsituations in all traffic, weather and roadconditions.
Pay particular attention to people andanimals near the vehicle.
PAP is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
NOTE
The PAP function measures the space andsteers the vehicle – the driver's role is to:
keep close watch of the area around thevehicle
follow the instructions on the center dis-play
change gears (reverse/forward) – a"ping" sound indicates when the drivershould change gears
regulate and maintain a safe speed
apply the brakes and stop.

Charging cable residual currentdevice
The charging cable has a circuit breaker thathelps protect against current overloads and ther-mal overheating.
WARNING
Charging the hybrid battery may only be donefrom approved, grounded 120/240 V outlets(AC, alternating current). If the electrical cir-cuit or electrical socket's capacity is notknown, let a licensed electrician inspect theelectrical circuit's capacity. Using a chargelevel that exceeds the electrical circuit's orelectrical outlet's capacity may start a fire ordamage the electrical circuit.
WARNING
The charging cable's residual currentbreaker helps protect the vehicle's charg-ing system but cannot ensure that an cur-rent overload will never occur.
Never use visibly worn or damaged elec-trical sockets. Doing so could lead to firesor serious injury.
Never connect the charging cable to anextension cord.
Maintenance or replacement of the hybridbattery may only be performed by atrained and qualified Volvo service techni-cian.
If the charging cable's residual current device istriggered, the blue indicator light in the chargingmodule will not illuminate when the chargingcable is plugged into an electrical outlet (or thered warning light will glow steadily). Have the out-let checked by a licensed electrician or try usinganother wall outlet.

Steady glow for 2 seconds afterthe engine is started: Automaticfunction check.
Steady glow for more than 2 sec-onds: Fault in the ABS system. Thevehicle's regular brake system isstill working, but without the ABSfunction.
If the message Brake pedal Cha-racteristics changed Servicerequired is displayed, the "Brake-by-wire" system is not functioningproperly. Greater pressure will berequired to brake the vehicle.
AIn Canada.BIn the US.

WARNING
If the warning symbols for both brake faultand ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is normalwhen this occurs, drive carefully to thenearest workshop to have the brake sys-tem checked - an authorized Volvo work-shop is recommended.
If the brake fluid has fallen below the MINlevel in the brake fluid reservoir, the vehi-cle should not be driven until the brakefluid has been filled. The reason for thebrake fluid loss must be checked.

Brake Assist System
The brake enhancing system, Brake AssistSystem (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habitsand increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.

STARTING AND DRIVING
433
Braking on wet roads
Prolonged driving in heavy rain without brakingmay cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. Itwill then be necessary to apply greater pressureto the brake pedal. You should therefore maintaina greater distance to the vehicle ahead.
Firmly apply the brakes after washing the vehicleor driving on wet roads. This helps warm up thebrake discs, enabling them to dry more quicklyand protecting them against corrosion. Considerthe current traffic situation when braking.

Brakes (p. 431)
Braking on salted roads (p. 433)
Braking on salted roads
When driving on salted roads, a layer of salt mayform on the brake discs and brake pads.
This could increase stopping distance. Maintainan extra large safety distance to the vehicleahead. Make sure to also:
Apply the brakes from time to time to helpremove salt. Make sure braking does notpose a risk to any other road users.
Gently apply the brakes when you have fin-ished driving and before driving again.

Maintenance of the brake system
Regularly check the brake system componentsfor wear.
To keep the vehicle as safe and reliable as possi-ble, follow the Volvo service schedule specified inthe Warranty and Maintenance Records Informa-tion booklet. New and replaced brake pads andbrake discs do not provide optimal braking effectuntil they are "broken in" by driving a few hun-dred kilometers (miles). Compensate for thereduced braking effect by applying greater pres-sure to the brake pedal. Volvo recommends onlyusing brake pads approved for your Volvo.

CAUTION
The brake system's components should beregularly checked for wear.
Contact a workshop for advice on how to dothis or let a workshop perform the inspection- an authorized Volvo workshop is recom-mended.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUSTCONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES.
Quality grades can be found, where applica-ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample:
Treadwear 200 Traction AA Temperature A

TREADWEAR
The treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.

TRACTION
The traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance.
WARNING
The traction grade assigned to this tire isbased on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.

TEMPERATURE
The temperature grades are A (the highest), B,and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.

WARNING
The temperature grade for this tire is estab-lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.

pressure telltale. When the system detects a mal-function, the telltale will flash for approximatelyone minute and then remain continuously illumi-nated. This sequence will continue upon subse-quent vehicle start-ups as long as the malfunc-tion exists. When the malfunction indicator is illu-minated, the system may not be able to detect orsignal low tire pressure as intended.
TPMS malfunctions may occur for a variety ofreasons, 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
If tire pressure is too low, the low tire pressurewarning symbol is shown in the instrument panelalong with a message.
Tire pressure low Check tires, calibrateafter fill
Tire pressure system Temporarilyunavailable
Tire pressure system Service required
To keep in mind
Always calibrate the system after changingwheels or adjusting tire pressure. See the tirepressure placard on the driver's side B pillarfor Volvo-recommended tire pressures.
If you switch to a tire of another size than thefactory-mounted tires, the system must becalibrated for these tires to avoid false warn-ings.
If a spare wheel8 is used, it is possible thatthe tire pressure monitoring system will notwork correctly due to the differencesbetween the wheels.
The system does not replace the need forregular tire inspection and maintenance.
It is not possible to deactivate the tire pres-sure monitoring system.

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