BRAKE Brake circuit malfunction
The brake system is a hydraulic system con- sisting of two master cylinders and two sepa-rate brake circuits. If a problem should occurin one of these circuits, it is still possible tostop the vehicle with the other brake circuit. If the brake pedal must be depressed farther than normal and requires greater foot pres-sure, the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault hasoccurred. If this light comes on while driving or braking, stop immediately and check the brake fluidlevel in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal – do not pump thebrakes.
WARNING
If the fluid level is below the MIN mark in
the reservoir or if a BRAKE FAILURE
STOP SAFELY message is displayed in
the text window: DO NOT DRIVE. Have
the vehicle towed to a trained and qualified Volvo service technician and have thebrake system inspected.
NOTE
When the vehicle is at a standstill and the engine is idling, e.g. at a traffic light andthe brake pedal is depressed, the pedalmay go down slightly. This is a normalfunction of the power-assisted brake sys-tem.
Brake pad inspectionOn vehicles equipped with a jack*, the condi- tion of the brake pads can be checked byraising the vehicle (see page 198 for informa-tion about using the jack and removing awheel) and performing a visual inspection ofthe brake pads.
WARNING
• If the vehicle has been driven immedi- ately prior to a brake pad inspection,the wheel hub, brake components,etc., will be very hot. Allow time forthese components to cool before car-rying out the inspection.
• Apply the parking brake and put thegear selector in the Park (
P) position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.

WARNING
•Use the jack intended for the vehicle when changing a tire. For any otherjob, use stands to support the vehicle.
• The jack should be kept well-greasedand clean, and should not be dam-aged.
• Be sure the jack is on a firm, level,non-slippery surface.
• No objects should be placed betweenthe base of jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
• The jack must correctly engage thejack attachment.
• Never allow any part of your body tobe extended under a vehicle suppor-ted by a jack.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is run-ning. Never let the vehicle roll to a stop withthe engine switched off. If the power brakes are not working, consid- erably higher pressure will be required on thebrake pedal to compensate for the lack ofpower assistance. This can happen for exam- ple when towing your vehicle or if the engineis switched off when the vehicle is rolling. Thebrake pedal feels harder than usual.
Water on brake discs and brake pads
affects braking
Driving in rain and slush or passing throughan automatic car wash can cause water tocollect on the brake discs and pads. This willcause a delay in braking effect when thepedal is depressed. To avoid such a delaywhen the brakes are needed, depress thepedal occasionally when driving through rain,slush etc. This will remove the water from thebrakes. Check that brake application feelsnormal. This should also be done after wash-ing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strainwhen driving in mountains or hilly areas, orwhen towing a trailer. Vehicle speed is usuallyslower, which means that the cooling of thebrakes is less efficient than when driving onlevel roads. To reduce the strain on thebrakes, shift into a lower gear and let theengine help with the braking. Do not forgetthat, if you are towing a trailer, the brakes willbe subjected to a greater than normal load.
Anti-lock brakes (ABS)If the ABS warning lamp lights up there is a
malfunction in the ABS system (the standardbraking system will however function) and thevehicle should be driven cautiously to atrained and qualified Volvo service technicianfor inspection. The Anti-lock Braking System(ABS) helps to improve vehicle control (stop-ping and steering) during severe braking con-ditions by limiting brake lockup. When thesystem "senses" impending lockup, brakingpressure is automatically modulated in orderto help prevent lockup, which could lead to askid. The system performs a self-diagnostic test when the engine is started and when thevehicle first reaches a speed of approxi- mately 12 mph (20 km/h). The brake pedal
will pulsate several times and a sound may be audible from the ABS control module. This isnormal. To obtain optimal effect from the ABS sys- tem, constant pressure should be kept on thebrake pedal. Do not pump the brake pedal. The switching of the ABS modulator will be audible and the brake pedal will pulsate dur-ing braking. Please be aware that ABS doesnot increase the absolute braking potential ofthe vehicle. While control will be enhanced,ABS will not shorten stopping distances onslippery surfaces.

ABS with EBD (Electronic Brake Force
Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to therear brakes to help provide optimal brakingcapacity. The brake pedal will pulsate duringbraking, which is normal. If the BRAKE and ABS warning lights come on at the same time, this could indicate afault in the brake system.
1. Stop the vehicle in a suitable place and switch off the engine.
2. Restart the engine.
• If both warning lights go off, no further action is required.
• If both lights are still on after the enginehas been restarted, switch off the engineagain and check the brake fluid level (seepage 225 for the location of the brakefluid reservoir).
WARNING
If the fluid level is below the
MIN mark in
the reservoir or if a Brake failure –
Service urgent message is displayed in
the text window: DO NOT DRIVE. Have the vehicle towed to a trained and qualifiedVolvo service technician and have thebrake system inspected.
• If the brake fluid level is above the
MIN
mark, drive carefully to a trained and qualified Volvo service technician andhave the brake system inspected.
Emergency Brake Assistance (EBA)The EBA function is designed to provide full brake effect immediately in the event of sud-den, hard braking. The system is activated bythe speed with which you depress the brakepedal.
NOTE
• When the EBA system is activated, the brake pedal will go down and pressurein the brake system immediatelyincreases to the maximum level. Youmust maintain full pressure on thebrake pedal in order to utilize the sys-tem completely. There will be no brak-ing effect if the pedal is released. EBAis automatically deactivated when thebrake pedal is released.
• When the vehicle has been parked forsome time, the brake pedal may sinkmore than usual when the engine isstarted. This is normal and the pedalwill return to its usual position when itis released.

Points to keep in mind when towing a trailer
•When towing trailers
without brakes, the
maximum permissible trailer weight is 1,700 lbs (750 kg).
• If necessary, redistribute the weight ofany cargo in the trailer to avoid excessiveweight on the trailer hitch.
• The maximum trailer weight listed in thetable for All Wheel Drive models,5,000 lbs (2250 kg) is only applicablewhen there are not more than two occu-pants in the vehicle, in the front seats,with a combined weight of 300 lbs(135 kg), with no other cargo in the vehi-cle.
• The maximum weight listed for FrontWheel Drive models, 4,000 lbs (1800 kg)is only applicable when there are notmore than four occupants in the vehicle,in the front seats and second row ofseats, with a combined weight of 600 lbs(270 kg), with no other cargo in the vehi-cle.
• Vehicles used for towing a trailer on aregular basis, or for long-distance high-way towing should be equipped with anautomatic transmission oil cooler andVolvo's automatic self-leveling system forthe rear suspension. Consult your Volvoretailer. •
Volvo recommends the use of Volvotrailer hitches that are specially designedfor the vehicle.
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
• Increase tire pressure to recommendedfull inflation pressure. See chapter"Wheels and tires."
• When your vehicle is new, avoid towingheavy trailers during the first 620 miles(1,000 km).
• Engine and transmission are subject toincreased loads. Therefore, engine cool-ant temperature should be closelywatched when driving in hot climates orhilly terrain. Use a lower gear and turn offthe air conditioner if the temperaturegauge needle enters the red range.
• If the automatic transmission begins tooverheat, a message will be displayed inthe text window.
• Hauling a trailer affects handling, durabil-ity, and economy.
• It is necessary to balance trailer brakeswith the towing vehicle brakes to providea safe stop (check and observe state/local regulations). •
Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• Remove the ball and drawbar assemblywhen the hitch is not being used.
• Volvo recommends the use of syntheticengine oil when towing a trailer over longdistances or in mountainous areas.
NOTE
•When parking the vehicle with a trailer on a hill, apply the parking brakebefore putting the gear selector in
P.
When starting on a hill, put the gearselector in D before releasing the park-
ing brake. Always follow the trailermanufacturer's recommendations forwheel chocking.
• If you use the manual (Geartronic) shiftpositions while towing a trailer, makesure the gear you select does not puttoo much strain on the engine (usingtoo high a gear).

203
The tire pressure monitoring system

uses
sensors mounted in the tire valves to check inflation pressure levels. When the vehicle ismoving at a speed of approximately 20 mph(30 km/h) or faster, these sensors transmitinflation pressure data to a receiver located inthe vehicle.
USA – FCC ID: MRXG403MA4 A
This device complies with part 15 of the
FCC rules. Operation is subject to the fol- lowing conditions: (1) This device may notcause harmful interference, and (2) thisdevice must accept any interferencereceived, including interference that maycause undesired operation. When low inflation pressure is detected, TPMS will light up the tire pressure warn-ing light (also referred to as a telltale) in theinstrument panel (see page 61), and willdisplay a message in the text window. Thewording of this message is determined bythe degree of inflation pressure loss.
A On certain models, the FCC code is MRXTG315AM04
When low inflation pressure is detected, TPMS will light up the tire pressure warning light
(also referred to as a telltale) in the instrument panel and will display one of the following messages in the text window:
LOW
TIRE PRESS. CHECK TIRES or VERY LOW
TIRE PRESSURE.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and
TIRE PRESS SYST
SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold andinflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different sizethan the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure forthose tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitor-ing system (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illu-minates, you should stop and check yourtires as soon as possible, and inflate them to the proper pressure. Driving on a significantlyunder-inflated tire causes the tire to overheatand can lead to tire failure. Under-inflationalso reduces fuel efficiency and tire tread life,and may affect the vehicle's handling andstopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination of theTPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists. When the malfunction indicator is illu-minated, the system may not be able todetect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioning
