2006 VOLVO C70 brakes

At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed
than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard maintenance intervals.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo
area, the less the tendency to understeer.
WARNING!
Driving with the trunk open : Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment. If the trunk must be kept open for any reason,
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
CAUTION!
Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the engine could
result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper than 18
inches (48 cm).
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
pg. 99 Starting and driving
General information
the recommended pressure according to the vehicle load. See the "Tire pressure" section. Loads should be distributed
so that capacity weight or maximum permissible axle loads are not exceeded.
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.
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
ProCarManuals.com

Check state of the battery's charge.
Examine tires carefully (the spare tire as well), and replace those that are worn. Check tire pressures.
The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service
technician only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with a trained and qualified Volvo service technician if you intend to drive in countries where it may
be difficult to obtain the correct fuel.
Consider your destination. If you will be driving through an area where snow or ice are likely to occur, consider
snow tires.
2. To prevent injury from contact with hot surfaces, do not inspect your vehicle's transmission fluid yourself. Have your vehicle's transmission fluid
level inspected by a trained and qualified Volvo service technician.
pg. 101 Starting and driving
Fuel requirements
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an AKI octane rating of 91
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. ((RON + MON)/2). The minimum octane requirement is AKI 87 (RON 91).
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposits. Detergent gasoline is effective in keeping
injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good driveability and
fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with the service
station operator.
NOTE: Volvo does not recommend the use of store -bought fuel injector cleaning additives.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit
your vehicle's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only".
Leaded gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of
leaded gasoline will lessen the effectiveness of the emission control system and could result in loss of emission
warranty coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly
resulting in emission test failure for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Check Engine Light (malfunction indicator lamp) located on your instrument panel may light. If this occurs,
please return your vehicle to a trained and qualified Volvo service technician for maintenance.
Gasoline containing alcohol and ethers
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or
local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated"
fuel. Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page must
still be met.
Alcohol - Ethanol : Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to as

Overriding the shiftlock system
Shiftlock prevents the gear selector from being moved out of Park unless the ignition key is in position II and the
brake pedal is depressed.
In certain cases it may be necessary to move the gear selector from the Park position manually, for example if the
battery is discharged.
Manually overriding the Shiftlock system:
Apply the parking brake.
Depress the brake pedal.
There is a small cover behind P-R-N-D on the gear selector panel. Open the rear edge of the panel.
Insert the key blade (see page 88
) or a screwdriver into the opening and press it down until it bottoms and move the
gear selector out of the P position.

Brake system
Brake circuit malfunction
The brake system is a hydraulic system consisting of 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 system message is shown in the information
display: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the
brake system inspected.
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 five 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
ProCarManuals.com

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

Park assist (accessory)
ProCarManuals.com

General description
The rear park assist system is designed to assist you when backing into parking spaces, garages, etc. It utilizes
ultrasound sensors located in the rear bumper to gauge distance, and provides an audible signal when the vehicle is
being backed close to another vehicle, object, or a person.
When is park assist active?
Front: the system is active from the time the engine is started until the car exceeds a speed of approximately 10 mph
(15 km/h).
Rear : the system is activated when reverse gear is selected. The indicator light in the button will light up.
When the system is actively working:
The audio system's volume will be reduced.
An intermittent signal will be audible from the speakers to indicate that you are approaching a person, object,
parked vehicle, etc. The signals begin when the distance between the bumper and the object is:
Rear : approximately 5 feet (1.5 meters).
Front : approximately 2.5 ft (0.8 meters)
At a distance of approximately 1 foot (30 cm), the signal will become constant.
Deactivating park assist, front/rear
Press the Exit button on the center control panel (see the illustration on page 51). PARK ASSIST DEACTIVATED,
ENTER TO ACTIVATE will be displayed.
Press Enter to reactivate the system.
NOTE:
Rear park assist : towing a trailer, carrying bicycles in a rear-mounted carrier, etc, could trigger the rear park assist
system's sensors.
NOTE: Rear park assist is deactivated automatically when towing a trailer if Volvo original connector wiring is used.
Front park assist : it may not be possible to combine auxiliary headlights. and front park assist since these lights
could trigger the system's sensors.
WARNING!
These systems are designed to be a supplementary aid when parking the vehicle. They are not, however, intended to
replace the driver's attention and judgement.
CAUTION!
In certain circumstances, the park assist system may give unexpected warning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. This may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhaust pipes, etc. This does not indicate a fault in
the system.

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.

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.

Towing a trailer
General information
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
Maximum trailer weights recommended by Volvo are:
Trailers without brakes : 1,540 lbs (700 kg).
Trailers with brakes: 2,000 lbs (900 kg) Observe the legal requirements of the state/province in which the vehicles
are registered.
The maximum recommended hitch tongue load is 165 lbs (75 kg).
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:
Increase tire pressure to recommended full. See the chapter "Wheels and tires."
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km).
Maximum speed when towing a trailer: 50 m.p.h. (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 information display.
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.
