Brake system
BRAKE Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinders and two separate brake circuits. If a
problem should occur in one of these circuits, it is still possible to stop the vehicle with the other brake circuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping distance will
be longer.
A warning light in the instrument panel will light up to warn the driver that a fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
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 qualified Volvo service technician
and have the brake system inspected.
NOTE
When the vehicle is at a standstill and the engine is idling, e.g. at a traffic light and the brake pedal is depressed, the
pedal may go down slightly. This is a normal function of the power-assisted brake system.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Never let the vehicle roll
to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed approximately four times harder than usual to
make up for the lack of power assistance. This can happen for example when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The brake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect on the brake discs and
pads. This will cause a delay in braking effect when the pedal is depressed. To avoid such a delay when the brakes are
needed, depress the pedal occasionally when driving through rain, slush etc. This will remove the water from the
brakes. Check that brake application feels normal. This should also be done after washing or starting in very damp or
cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas or towing. Vehicle speed is usually
slower, which means that the cooling of the brakes is less efficient than when driving on level roads. To reduce the
strain on the brakes, shift into a lower gear and let the engine help with the braking. Do not forget that, if you are
towing a trailer, the brakes will be subjected to a greater than normal load.

Anti-lock brakes (ABS)
If the warning lamp lights up there is a malfunction of the ABS system
138 06 Starting and driving
Brake system
(the standard braking system will however function) and the vehicle should be driven cautiously to a trained and
qualified Volvo service technician for inspection. The Anti-lock Braking System (ABS) helps to improve vehicle
control (stopping and steering) during severe braking conditions by limiting brake lockup. When the system "senses"
impending lockup, braking pressure is automatically modulated in order to help prevent lockup, which could lead to a
skid.
The system performs a self -diagnostic test when the engine is started and when the vehicle first reaches a speed
of approximately 12 mph (20 km/h) . The brake pedal will pulsate several times and a sound may be audible from the
ABS control module. This is normal.
To obtain optimal effect from the ABS system, constant pressure should be kept on the brake pedal. Do not pump the
brake pedal.
The switching of the ABS modulator will be audible and the brake pedal will pulsate during braking. Please be aware
that ABS does not increase the absolute braking potential of the vehicle. While control will be enhanced, ABS will not
shorten stopping distances on slippery surfaces.
ABS with EBD (Electronic Brake Force Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity. The brake pedal will pulsate during braking, which is normal.
If the BRAKE and ABS warning lights come on at the same time, this could indicate a fault in the brake system.
1. Stop the vehicle in a suitable place and switch off the engine.
2. Restart the engine.
3. If both warning lights go off, no further action is required.
4. If both lights are still on after the engine has been restarted, switch off the engine again and check the brake fluid
level (see page 196
for the location of the brake fluid 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 qualified Volvo service technician
and have the brake system inspected.
5. If the brake fluid level is above the MIN mark, drive carefully to a trained and qualified Volvo service technician
and have the brake system inspected.
Emergency Brake Assistance (EBA)
ProCarManuals.com

The EBA function is designed to provide full brake effect immediately in the event of sudden, hard braking. The
system is activated by the speed with which you depress the brake pedal.
NOTE
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. You must maintain full pressure on the brake pedal in order to utilize the system
completely. There will be no braking effect if the pedal is released. EBA is automatically deactivated when the brake
pedal is released.
When the vehicle has been parked for some time, the brake pedal may sink more than usual when the engine is
started. This is normal and the pedal will return to its usual position when it is released.

Stability system
Dynamic Stability Traction Control (DSTC)
The stability system consists of a number of functions designed help reduce wheel spin, counteract skidding, and to
generally help improve directional stability.
NOTE
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)
This function is designed to help reduce wheel spin by transferring power from a drive wheel that begins to lose
traction to the wheel on the opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of the DSTC's permanent functions and cannot be switched off.
Spin control (SC)
The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is accelerating.
Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose sand, it may be
advisable to temporarily switch off this function for maximum tractive force.
Temporarily switching off Spin control
1. Turn the thumb wheel (1) on the left-side steering wheel lever until the DSTC menu is displayed.
2. Hold down the RESET button (2) to toggle between DSTC SPIN CONTROL ON or OFF.
Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cornering, by braking one or more of the wheels if
the vehicle shows a tendency to skid or slide laterally.)
WARNING
The car's handling and stability characteristics will be altered if the DSTC system functions have been disabled.
ProCarManuals.com

NOTE
The message DSTC SPIN CONTROL OFF indicates that the stability system's spin control function has
temporarily been switched off.
The stability control indicator light will illuminate and remain on until spin control has been reactivated.
DSTC ON indicates that all system functions are active.
The spin control function is automatically enabled each time the engine is started.

Towing
CAUTION
Please check with state and local authorities before attempting this type of towing, as vehicles being towed are
subject to regulations regarding maximum towing speed, length and type of towing device, lighting, etc.
If the vehicle's battery is dead, do not attempt to start the vehicle by pushing or pulling it as this will damage the
three-way catalytic converter(s). The engine must be jump started using an auxiliary battery (see page 143
).
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the
flat bed. Consult the tow truck operator.
WARNING
Remember that the power brakes and power steering will not function when engine is not running. The braking
and steering systems will function but the brake pedal pressure required is 3 - 4 times above normal and greater
steering effort must be exerted.
The towing eyelets must not be used for pulling another vehicle out of a ditch or for any similar purpose involving
severe strain.
Do not use the towing eyelets to pull the vehicle up onto a flat bed tow truck.

Towing a trailer
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
Maximum trailer weight recommended by Volvo is:
Trailers without brakes: 1650 lbs (750 kg)
Trailers with brakes:
2" (50 mm) ball - 3300 lbs* (1500 kg), 1 7/8" (47 mm) ball - 2000 lbs (900 kg). Observe the legal requirements of the
state/province in which the vehicles are
All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailer hitch installation should not
interfere with the proper operation of this bumper system.
Trailer towing does not normally present any particular problems, but take into consideration:
ProCarManuals.com

Increase tire pressure to recommended full. See section "Wheels and tires."
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1000 km).
Recommended hitch tongue load is:
Trailer weights below 2,650 lbs (1,200 kg) - 110lbs (50kg)
Trailer weights above 2,650 lbs (1,200 kg) - 165lbs (75kg)
Maximum speed when towing a trailer: 50 mph (80 km/h).
Engine and transmission are subject to increased loads. Therefore, engine coolant temperature should be closely
watched when driving in hot climates or hilly terrain. Use a lower gear and turn off the air conditioner if the
temperature gauge needle enters the red range.
If the automatic transmission begins to overheat, a message will be displayed in the text window.
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability, and economy.
It is necessary to balance trailer brakes with the towing vehicle brakes to provide a safe stop (check and observe
state/local regulations).
Do not connect the trailer's brake system directly to the vehicle's brake system.
More frequent vehicle maintenance is required.
Remove the ball and drawbar assembly when the hitch is not being used.
Volvo recommends the use of synthetic engine oil when towing a trailer over long distances or in mountainous
areas.
WARNING
Bumper-attached trailer hitches must not be used on Volvos, nor should safety chains be attached to the bumper.
Trailer hitches attaching to the vehicle rear axle must not be used.
Never connect a trailer's hydraulic brake system directly to the vehicle brake system, nor a trailer's lighting system
directly to the vehicle lighting system. Consult your nearest trained and qualified Volvo service technician for correct
installation.
When towing a trailer, the trailer's safety wire must be correctly fastened to the hole or hook provided in the
trailer hitch on the vehicle. The safety wire should never be fastened to or wound around the drawbar ball.
NOTE
When parking the vehicle with a trailer on a hill, apply the parking brake before putting the gear selector in P
(first/reverse gear on manual transmissions). Always follow the trailer manufacturer's recommendations for wheel
chocking.
When starting on a hill, put the gear selector in D before releasing the parking brake.
If you use the manual (Geartronic) shift positions while towing a trailer, make sure
145 06 Starting and driving
Towing a trailer
the gear you select does not put too much strain on the engine (using too high a gear).
The drawbar assembly/trailer hitch may be rated for trailers heavier than the vehicle is designed to tow. Please
adhere to Volvo's recommended trailer weights.

Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to - 31°F (-35°C). See section "Coolant". The use of "recycled"
antifreeze is not approved by Volvo. Different types of antifreeze must not be mixed.
Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator. Your Volvo retailer stocks plenty
of Volvo engine coolant to protect your vehicle during cold weather.
Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. In addition, in
extremely cold weather conditions it is worthwhile to add fuel line de -icer before refueling.
The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weather starting as
