NOTE:
The S60 R has a standard FOUR-C system consisting of Comfort, Sport, and Advanced sport modes. The buttons for
controlling these driving modes are located in center instrument panel, above the ventilation system panel vents, see
the illustration below. These buttons can be pressed at any time to change driving modes. An indicator light in the
selected button will come on to indicate the driving mode that is currently selected.
This system is based on a number of sensors that continuously monitor factors such as the car's lateral and vertical
movements, speed, and movements of the wheels. The sensors receive data up to 500 times per second, which is used
to provide extremely fast and precise adjustment of each shock absorber. The system adjusts the stiffness of the shock
absorbers approximately 100 times per second.
Comfort
The Comfort mode chassis setting offers the greatest amount of shock absorption and the softest ride. This mode is
recommended for long-distance driving, or when driving in slippery conditions. The indicator light in the button will
be off when this mode is selected.
If Comfort mode was selected when the engine was switched off, this mode will still be active when the engine is
restarted.
Sport
In this mode, shock absorption is stiffer to reduce the car's body sway during cornering and to provide more immediate
steering response. The indicator light in the button will come on to indicate that Sport mode has been selected.
If this setting was selected when the engine was switched off, Sport mode will still be active when the engine is
restarted.
S60 R buttons on the dashboard
Advanced Sport (S60R only)
In this mode, movement of the shock absorbers is minimal, response from pressure on the throttle pedal is more direct,
and body sway in curves or when cornering is sharply reduced.
If Advanced sport mode was selected when the engine was switched off, Sport mode will be active when the engine
is restarted.

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 car 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 car towed to a Volvo retailer and have the brake system inspected.
NOTE: When the car 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.
pg. 97 Starting and driving
Anti-lock brakes (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will however
function) and the vehicle should be driven cautiously to a Volvo retailer 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
ProCarManuals.com
Page 75 of 132

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.
Stop the car in a suitable place and switch off the engine.
Restart the engine.
If both warning lights go off, no further action is required.
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 141
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 car towed to a Volvo retailer and have the brake system inspected.
If the brake fluid level is above the MIN mark, drive carefully to an authorized Volvo retailer and have the brake
system inspected.
Emergency Brake Assistance (EBA)
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.
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. EBA is automatically deactivated when the brake pedal is released.
When the car 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.

General information
Your vehicle is equipped with tires according to the vehicle's tire information placard on the B-pillar (the structural
member at the side of the vehicle, at the rear of the driver's door opening), or on the inside of the fuel filler door on
Canadian models.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces. It should be noted
however that the tires have been developed to give these features on snow/ice-free surfaces.
Certain models are equipped with "all-season" tires, which provide a somewhat higher degree of road holding on
slippery surfaces than tires without the "all-season" rating. However, for optimum road holding on icy or snow-
covered roads, we recommend suitable winter tires on all four wheels.
When replacing tires, be sure that the new tires are the same size designation, type (radial) and preferably from the
same manufacturer, on all four wheels. Otherwise there is a risk of altering the car's roadholding and handling
characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be suspended off the floor or placed on their sides
on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not be
suspended.
CAUTION:
Tires should preferably be stored in a cool, dry, dark place, and should never be stored in close proximity to solvents,
gasoline, oils, etc.

Tread wear indicator
The tires have wear indicator strips running across or parallel to the tread. The letters TWI are printed on the side of
the tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire
should be replaced. Tires with less than 1/16" (1.6 mm) tread offer very poor traction.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.
WARNING!
- The wheel and tire sizes for your Volvo are specified to meet stringent stability and handling requirements.
Unapproved wheel/ tire size combinations can negatively affect your vehicle's stability and handling. Approved tire
sizes are shown in the Tire inflation pressure tables on page 116
.
- Any damage caused by installation of unapproved wheel/tire size combinations will not be covered by your new
vehicle warranty. Volvo assumes no responsibility for death, injury, or expenses that may result from such
installations.
pg. 113 Wheels and tires
New tires
Remember that tires are perishable goods. As of 2000, the manufacturing week and year will be indicated with 4 digits
(e.g. 1502 means that the tire illustrated was manufactured during week 15 of 2002).
Tire age
Tires degrade over time, even when they are not being used, which can affect their reliability and roadholding
characteristics. Therefore, all tires older than 6 years (including the spare tire and winter tires) should be inspected by a
qualified technician, regardless of appearance or mileage. Heat caused by hot climates or frequent high loading
conditions can accelerate the aging process.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration above).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy:
Maintain correct tire pressure. See the tire pressure table on page 116.
Drive smoothly: avoid fast starts, hard braking and tire screeching.
ProCarManuals.com
Page 78 of 132

Tire wear increases with speed.
Correct front wheel alignment is very important.
Unbalanced wheels impair tire economy and driving comfort.
Tires must maintain the same direction of rotation throughout their lifetime.
When replacing tires, the tires with the most tread should be mounted on the rear wheels to reduce the chance of
oversteer during hard braking.
Hitting curbs or potholes can damage the tires and/or wheels permanently.

Tire inflation placards on US models
Tire inflation
Check tire inflation pressure regularly. A table listing the recommended inflation pressure for your vehicle can be
found on page 116
. Tire inflation pressure placards are also located on the driver's side B-pillar (the structural member
at the side of the vehicle, at the rear of the driver's door opening), or on the inside of the fuel filler door on Canadian
models. These placards indicate the designation of the factory-mounted tires on your vehicle, as well as load limits and
inflation pressure.
Tire inflation placard on Canadian models
NOTE: The placards shown indicate inflation pressure for the tires installed on the car at the factory only.
Use a tire gauge to check the tire inflation pressure, including the spare, at least once a month and before long trips.
You are strongly urged to buy a reliable tire pressure gauge, as automatic service station gauges may be inaccurate.
Use the recommended cold inflation pressure for optimum tire performance and wear.
Under-inflation or over-inflation may cause uneven treadwear patterns.
WARNING!
ProCarManuals.com
Page 79 of 132

-Under-inflation is the most common cause of tire failure and may result in severe tire cracking, tread separation, or
"blowout," with unexpected loss of vehicle control and increased risk of injury.
-Under-inflated tires reduce the load carrying capacity of your vehicle.
When weather temperature changes occur, tire inflation pressures also change. A 10-degree temperature drop causes a
corresponding drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures frequently and adjust them to the
proper pressure, which can be found on the vehicle's tire information placard or certification label.
Checking tire pressure
Cold tires
Inflation pressure should be checked when the tires are cold.
The tires are considered to be cold when they have the same temperature as the surrounding (ambient) air.
This temperature is normally reached after the car has been parked for at least 3 hours.
pg. 115 Wheels and tires
After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If you have to drive
farther than this distance to pump your tire(s), check and record the tire pressure first and add the appropriate air
pressure when you get to the pump.
If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tires are hot from driving and it
is normal for pressures to increase above recommended cold pressures. A hot tire at or below recommended cold
inflation pressure could be significantly under-inflated.
To check inflation pressure:
1. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pressure.
3. Replace the valve cap.
4. Repeat this procedure for each tire, including the spare.
5. Visually inspect the tires to make sure there are no nails or other objects embedded that could puncture the tire and
cause an air leak.
6. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
NOTE:
If you overfill the tire, release air by pushing on the metal stem in the center of the valve. Then recheck the pressure
with your tire gauge.
Some spare tires require higher inflation pressure than the other tires. Consult the tire inflation table on page 116 or
see the inflation pressure placard.

b. Self supporting run flat tires. See page 118
for more information.
Optional tire pressure. These inflation pressures may only be used when the vehicle is not fully loaded.
pg. 117 Wheels and tires
Tire Pressure Monitoring System (TPMS) - option on certain U.S. models only
The tire pressure monitoring system uses sensors mounted in the tire valves to check inflation pressure levels. When
the vehicle is moving at a speed of 20 mph (30 km/h) or faster, these sensors transmit inflation pressure data to a
receiver located in the vehicle.
