2006 VOLVO C70 coolant

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

After the engine has started, first remove the negative (-) terminal jumper cable. Then remove the positive (+)
terminal jumper cable.
WARNING!
PROPOSITION 65 WARNING!
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of
California to cause cancer and reproductive harm. Wash hands after handling.
WARNING!
Do not connect the jumper cable to any part of the fuel system or to any moving parts. Avoid touching hot
manifolds.
Batteries generate hydrogen gas, which is flammable and explosive.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
Never expose the battery to open flame or electric spark.
Do not smoke near the battery.
Failure to follow the instructions for jump starting can lead to personal injury.

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.

pg. 155 Maintenance and servicing
Maintaining your car
Owner maintenance
Periodic maintenance requirements and intervals are described in your vehicle's Warranty and Service Records
Information booklet.
The following points can be carried out between the normally scheduled maintenance services.
Each time the car is refueled:
Check the engine oil level
Clean the windshield, windshield wipers, headlights, and tail lights
Monthly:
Check cold tire pressure in all tires. Inspect the tires for wear.
Check that engine coolant and other fluid levels are between the indicated "min" and "max" markings.
Clean interior glass surfaces with a glass cleaner and soft paper towels.
Wipe driver information displays with a soft cloth.
Visually inspect battery terminals for corrosion. Corrosion may indicate a loose terminal connector, or a battery near
the end of its useful service life. Consult your Volvo retailer for additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup of dirt, and corrosion that
can be caused by salt residues.
ProCarManuals.com

Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Oil that is lower than the specified quality can damage the engine.
Always add oil of the same type and viscosity as already used.
Never fill oil above the MAX mark. This could cause an increase in oil consumption.
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces.
pg. 159 Maintenance and servicing
Fluids
Washer fluid
The washer fluid reservoir is located in the engine compartment and holds approximately 6.8 US qts (6.5 liters).
During cold weather, the reservoir should be filled with windshield washer solvent containing antifreeze.
Coolant
Normally, the coolant does not need to be changed. If the system must be drained, consult your Volvo retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has
a lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/ 50 mix of water and antifreeze).
CAUTION!
ProCarManuals.com

The cooling system must always be kept filled to the correct level, and the level must be between the MIN and
MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly!
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.
If it is necessary to top off the coolant when the engine is warm, unscrew the expansion tank cap slowly so that the
overpressure dissipates.
pg. 160 Maintenance and servicing
Fluids
Brake fluid
The brake fluid should always be between the MIN and MAX marks on the side of the reservoir. Check, without
removing the cap, that there is sufficient fluid in the reservoir.
Fluid type: DOT 4+ boiling point >536°F (280°C), P/N 9437433
Replace: The fluid should be replaced according to the intervals specified in the Warranty and Service Records
Information booklet. When driving under extremely hard conditions (mountain driving, etc), it may be necessary to
replace the fluid more often. Consult your Volvo retailer. Always entrust brake fluid changing to a trained and
qualified Volvo service technician.
Power steering fluid
The fluid level should always be between the MIN and MAX marks.
