2006 VOLVO S40 cooling

14. Temperature gauge
The gauge indicates the temperature of the engine cooling system. If the temperature is abnormally high and the needle
enters the red zone, a message is shown in the display. Bear in mind that auxiliary lamps in front of the air intake
reduce the cooling capacity at high outside temperatures and high engine loads.
15. Indicator and warning symbols
1. Models with All Wheel Drive have a tank volume of 15 US gallons (57 liters).
Models with engine code 39 have a fuel tank capacity of 14 US gallons (53 liters). This code is the 6th and 7th digits
from the left in your vehicle's VIN number. See page 176
for the location of the VIN plate.
pg. 35 Indicator and warning symbols
Function check
The indicator and warning symbols light up when you turn the ignition key to the driving position (position II) before
starting. This shows that the symbols are functioning. When the engine starts, all symbols go out. If the engine is not
started within 5 seconds, all of the symbols except CHECK ENGINE and
will go out. Certain symbols may not
have their functions illustrated, depending on the car's equipment. The PARK BRAKE symbol will not go out until the
parking brake has been released.
Symbols in the center of the instrument panel
Warning symbol
The red warning symbol lights up to indicate a fault that could affect the car's driveability. A text explaining the nature
of the fault will also be shown in the information display. The symbol and accompanying text will remain on until the

If the red warning symbol lights up:
1. Stop the car as soon as possible in a suitable location.
2. Read the message in the information display.
3. Follow the instructions provided, or contact a trained and qualified Volvo service technician.

Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your vehicle, lead has been strongly linked to certain forms of cancer. Many fuels
contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you live in an
area where you must fill your own gas tank, take precautions.
These may include:
standing upwind away from the filler nozzle while refueling
pg. 96 Fuel requirements (contd.)
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during
refueling
wearing neoprene gloves while handling a fuel filler nozzle.
WARNING!
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the
vehicle to your retailer for correction.
Use of Additives
With the exception of fuel line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your vehicle's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.
Fuel filler door
Press the button on the light switch panel (see the illustration on page 41
) with the ignition switched off to unlock the
fuel filler door. Please note that the fuel filler door will remain unlocked until the vehicle begins to move forward. An
audible click will be heard when the fuel filler door relocks.
If you intend to leave your vehicle while it is being refueled, this feature enables you to lock the doors/trunk while
leaving the fuel filler door unlocked.
You can also keep the vehicle locked if you remain inside it during refueling. The central locking button does not lock
the fuel filler door.
Be sure the fuel filler door is not obstructed and is completely closed after refueling.
Open the fuel filler cap slowly during hot weather.
Refueling
The fuel tank is designed to hold approximately 15.9 US gallons (60 liters)
1 with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank capacity will be somewhat
less than the specified maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "Reid
vapor pressure" characteristics, and terrain can affect the fuel pump's ability to supply the engine with an adequate
supply of fuel. Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the
fuel warning light comes on.
1. Models with All Wheel Drive have a tank volume of 15 US gallons (57 liters).
Models with engine code 39 have a fuel tank capacity of 14 US gallons (53 liters). This code is the 6th and 7th digits
from the left in your vehicle's VIN number. See page 176
for the location of the VIN plate.

Changing engine oil and oil filter
See page 179
for oil specifications. Refer to the Warranty and Service Records Information booklet for information on
the oil change intervals.
NOTE:
Volvo does not recommend the use of oil additives.
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge. Please consult your Volvo retailer.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This is especially important during the period up to
the first scheduled maintenance service.
CAUTION!
Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Always add oil of the same type and viscosity as already used.
The car should be parked on a level surface when the oil is checked.
Location of dipstick and oil filler cap
If the engine is warm , wait for at least 10-15 minutes after the engine has been switched off before checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add approximately 1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal operating temperature.

Coolant reservoir
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!
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
over-pressure dissipates.
