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 when towing a trailer. 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)
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 that 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 m.p.h. (20 km/h).
The brake pedal will pulsate several times and a sound may be audible from the ABS control module. This is normal.
pg. 112 Starting and driving
Brake system
Electronic Brake Force Distribution (EBD)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity.
NOTE: To obtain optimal effect from the ABS system:
Keep constant pressure 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.
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will still function)
and the vehicle should be driven cautiously to a trained and qualified Volvo service technician for inspection.
WARNING!
If the BRAKE and ABS warning symbols light at the same time, there may be a problem in the brake system. If the
brake fluid level is normal in these circumstances, drive carefully to the nearest Volvo workshop to have the brake
system checked.
Emergency Brake Assistance - EBA
EBA is designed to provide full brake effect immediately in the event of sudden, hard braking. The system is activated
by the speed with which the brake pedal is depressed.
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
ProCarManuals.com

increases to the maximum level. Maintain full pressure on the brake pedal in order to utilize the system completely.
EBA is automatically deactivated when the brake pedal is released.
pg. 113 Starting and driving
Stability system
The car is equipped with DSTC (Dynamic Stability and Traction Control). This system consist of the following
functions:
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 monitors and compares the rotational
speed of the drive wheels. If one of the drive wheels shows a tendency to spin, the difference in speed is immediately
detected.
TC is most active at low speeds, and a pulsating sound will be audible when the system is regulating wheel spin. This
is quite normal.
This function cannot be disabled.
Spin control - SC
The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is accelerating.
This is done by temporarily reducing engine torque to the drive wheels, which helps improve tractive force.
Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose sand, it may be
advisable to temporarily disable this function for maximum tractive force.
Disabling the spin control function:
This is done in the menu system, and will be indicated by a text messages in the information display.
Turn control (A) on the left steering wheel lever until the DSTC menu is displayed.
Press and hold down the reset button (B) until DSTC SPIN CONTROL OFF or DSTC ON is displayed.
The anti-spin function will be automatically reactivated when the engine is started.
WARNING!
The car's handling and stability characteristics will be altered with the spin control function disabled.
Active yaw control - AYC
This function helps maintain directional stability, for example when cornering, by braking one or more of the wheels if

Screw the towing eyelet in place first by hand and then using the tire iron until it is securely in place (3).
After the vehicle has been towed, the eyelet should be unscrewed and returned to its storage place. Press the plastic
cover in bumper back into position.
WARNING!
Volvo does not recommend towing a disabled vehicle behind another vehicle. Significant difficulty in steering and
braking, combined with unfavorable weather, traffic, and road conditions may make it impossible to maintain
vehicle control.
Towing a vehicle with all four wheels on the ground
Apply the parking brake.
Insert the key into the ignition to unlock the steering wheel. The steering wheel must be unlocked. With the engine
off and the vehicle at a standstill, great effort will be required to turn the steering wheel.
WARNING!
Towing a vehicle with a locked steering wheel will make the vehicle impossible to steer.
Turn the ignition key to position II.
Place the gear selector in neutral. For vehicles with automatic transmissions, follow instruction on page 110,
"Shiftlock override" to allow the gear selector to be moved from the Park position.
Keep firm pressure on the brake pedal while releasing the parking brake.
When towing has been completed, return the gear selector to Park (automatic) or Reverse (manual) and apply the
parking brake.
pg. 118 Starting and driving
Towing
The following points should also be observed:
Never exceed 50 mph (80 km/h). Never exceed local towing speed limits and heed all local towing restrictions.
Never tow farther than 50 miles (80 km).
Keep the tow rope taut at all times while the vehicle is in motion.
The disabled vehicle should be towed in the forward direction only.
WARNING!
Never allow a vehicle to be towed without a driver behind the wheel of the disabled vehicle.
Never remove the key from the ignition while the vehicle is moving. The steering wheel could lock, making it
impossible to steer the vehicle.
When the engine is not running, steering resistance and the effort needed to apply the brakes will be great.
Never attempt to tow a vehicle with a dead battery at night.
CAUTION!
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, marker flags, etc.

Your vehicle is equipped with a tire sealing system that enables you to temporarily seal a hole in the tread surface and
re-inflate a flat tire, or to adjust a tire's inflation pressure.
The tire sealing kit is stowed behind the ski hatch in the center of the rear seat backrest.
The jack, and lug wrench are secured in a foam plastic block located under the floor panel in the trunk.
The system consists of an air compressor, an integrated container for the sealing compound, wiring to connect the
system to the vehicle's electrical system via one of the 12-volt sockets, and a hose used to connect the system to the
tire's inflation valve.
NOTE:
The tire sealing system is only intended to seal holes on the tire's tread area, not the sidewall.
Tires with large holes or tears cannot be repaired with the tire sealing system.
WARNING!
After using the tire sealing system, the vehicle should not be driven farther than approximately 120 miles (200
km). Have the tire replaced as soon as possible.
The vehicle should not be driven faster than 50 mph (80 km/h) while using a tire that has been temporarily
repaired with the tire sealing system.
After using the tire sealing system, drive carefully and avoid abrupt steering maneuvers and sudden stops.

Temporarily repairing a flat tire
Before using the tire sealing system, observe the following:
WARNING!
Never leave the tire sealing system unattended when it is operating.
Keep the tire sealing system kit away from children.
The vehicle's engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be
sure the vehicle is parked in a well ventilated place before using the system.
Be sure the vehicle is parked safely off the road and away from moving traffic.
Apply the parking brake.
Do not remove any foreign objects (nails, etc.) from the tire.
Temporarily repairing a flat tire is done in two stages.
In the first stage, the hole is sealed by pumping sealing compound into the tire. The car is then driven a short
distance to distribute the sealing compound in the tire.
In the second stage, the tire's inflation pressure is checked and adjusted if necessary.
Stage 1: Sealing the hole
Peel off the speed limit sticker (1) and affix it to the steering wheel hub where it will be clearly visible to the driver.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Pull out the electrical wire (5) and hose (4) from the side compartment (3).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
Release the safety catch (6) and turn the orange colored section of the sealing kit (7), which holds the sealing
compound container, 90 degrees until it clicks into the vertical position.
Start the vehicle's engine.
Start the tire sealing system's compressor by pressing the switch (2) to position I.
NOTE: The air pressure gauge (9) will temporarily show an increase in pressure to approximately 88 psi (6 bar) while
the sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately
one minute.
pg. 143 Wheels and tires
Tire sealing system
WARNING!
ProCarManuals.com

Contact with the sealing compound may cause skin irritation. If contact occurs, wash the affected area immediately
with soap and water.
Never stand next to the tire being inflated when the compressor is in operation. If cracks, bubbles, etc. form on the
tire, switch off the compressor immediately. If there is visible damage to the sidewall or the rim, the tire cannot be
repaired. The vehicle should not be driven if this occurs. Contact a towing service or Volvo On Call Roadside
Assistance if applicable.
Within seven minutes, inflate the tire to between 22 - 50 psi (1.8 - 3.5 bar). Switch off the compressor briefly to get a
clear reading from the pressure gauge (9).
CAUTION!
If the pressure remains below 22 psi (1.8 bar) after approximately seven minutes, turn off the compressor. In this
case, the hole is too large to be sealed and the vehicle should not be driven.
Disconnect the electrical wire from the 12-volt socket.
Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
Fold down the orange section of the tire sealing system to its original (horizontal) position and press the safety catch
into place.
Safely stow the tire sealing system kit in a convenient place as it will soon be used again to check the tire's inflation
pressure.
Immediately drive the vehicle for approximately 2 miles (3 km) to distribute the sealing compound in the tire.
WARNING!
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the car
in a safe place. Recheck the tire for bumps, cracks, or other visible damage, and recheck its inflation pressure. If the
pressure is below 16 psi (1.3 bar), do not continue driving. Have the vehicle towed to a workshop or Volvo retailer.
Stage 2: Checking inflation pressure
Park the car in a safe place.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
Start the vehicle's engine.
Check the tire's inflation pressure on the gauge (9).
NOTE: In dark conditions, switching on the tire sealing system's compressor will illuminate the pressure gauge.
Inflate the tire to the correct pressure as indicated in the tire inflation tables on page 116. If the tire needs to be
inflated, start the tire sealing system's compressor. If necessary, release air from the tire by pressing the vent button (8).
Turn off the compressor (press switch 2 to the 0 position) when the correct inflation pressure has been reached.
