2000 VOLVO S40 check engine light

The entire process, including inflation and deflation of the airbags, takes approximately two-tenths of a second.WARNING!
· As its name implies, SRS is designed to be a SUPPLEMENT to - not a replacement for - the three-point belt
system. For maximum protection, wear seat belts at all times. Be aware that no system can prevent all possible
injuries that may occur in an accident.
· When installing any optional equipment, make sure that the SRS system is not damaged. Do not attempt to service
any component of the SRS yourself. Attempting to do so may result in serious personal injury. If a problem arises,
take your car to the nearest authorized Volvo retailer for inspection as soon as possible.
pg. 5 Volvo SRS
A self -diagnostic system incorporated into the sensor monitors the SRS. If a fault is detected, the "SRS" warning light
will illuminate. The light is included in the warning/indicator light cluster in the instrument panel. Normally, the SRS
warning lamp should light up when the ignition is switched on and should go out after 5 seconds or when the engine is
started. Check that this light is functioning properly every time the car is started.
The following items are monitored by the self -diagnostic system:
· Sensor unit
· Cable harness
· Gas generator ignitersWARNING!
Never drive an SRS equipped car with your hands on the steering wheel pad / airbag housing.

pg. 20 Warning lights
The warning lights described on pages 20 and 21 should never stay on when driving
When the ignition key is turned on and before the engine starts, all of the warning lights should go on to test the
function of the bulbs. Should a light not go off after the engine has started, the system indicated should be
inspected. However, the parking brake reminder light will not go off until the parking brake has been fully
released.
Supplemental Restraint System (SRS)
If the light comes on (or stays on after the vehicle has started), the SRS diagnostic system has detected a fault.
Drive to an authorized Volvo retailer for an inspection of the system. See the SRS section for more information.
Check Engine Lamp
If the lamp comes on (or stays on after the vehicle has started), the engine diagnostic system has detected a
possible fault in the emission control system. Although driveability may not be affected, see an authorized Volvo
retailer as soon as possible for inspection.
NOTE : If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check
Engine Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
Oil pressure warning light
If the light comes on while driving, stop the car and then stop the engine immediately and check the engine oil
level . See page 112.
If the light stays on after restart, have the car towed to the nearest authorized Volvo
retailer. After hard driving, the light may come on occasionally when the engine is idling. This is normal,
provided it goes off when the engine speed is increased.
Parking brake reminder light
This light will be on when the parking brake (hand brake) is applied. The parking brake lever is situated
between the front seats.
WARNING!
ProCarManuals.com

Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
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.
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 car'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 methly-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Check Engine Lamp located on your instrument panel may light. If this occurs, please return your vehicle to
an authorized Volvo retailer for service.
pg. 59 Fuel requirements, Refueling
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI 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).
Gasoline containing alcohol and ethers
"Oxygenated fuels"
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 Ethyl alcohol, or "Gasohol".
Ethers — MTBE
Fuels containing up to 15% MTBE may be used.
ProCarManuals.com

Refueling
The fuel tank is designed to hold approximately: 16 US gallons (60 liters) with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather.
Fuel filler door
The fuel filler door (on the left rear fender) is unlocked along with the car's central locking system.
Open fuel filler cap slowly during hot weather conditions.
See page 95
in case the fuel filler door does not unlock along with the central locking system
CAUTION:
· Do not refuel with the engine running *. Turn the ignition off or to position I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
· After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
· Avoid spilling gasoline during refueling. Gasolines containing alcohol can cause damage to painted surfaces, which
may not be covered under the New Vehicle Limited Warranty.
· Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
· Do not overfill the fuel tank. Overfilling could damage the emission control system.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo original or
approved fuel filler caps.
pg. 60 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
· Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
· Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
· Drive carefully and avoid rapid acceleration and hard braking.
· Do not exceed posted speed limits.
· Avoid carrying unnecessary items (extra load) in the car.
· Maintain correct tire pressure. Check tire pressure regularly (check when tires are cold).
· Remove snow tires when threat of snow or ice has ended.
· Note that roof racks, ski racks, etc., increase air resistance and thereby fuel consumption.
· Avoid using automatic transmission kickdown feature unless necessary.
ProCarManuals.com

· Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and the windows down.
· Utilizing the fuel consumption modes in the Trip Computer can help you "learn" how to drive more economically.
Other factors which decrease gas mileage are:
· Worn or dirty spark plugs
· Incorrect spark plug gap
· 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 Service intervals.
NOTE : The automatic transmission's ( D)rive position should be used as often as possible to help improve fuel
economy.
WARNING!
It is recommended that tires of the same make and dimensions be used on all four wheels (including the use of snow
tires). Do not use bias ply tires as this will adversely alter vehicle handling characteristics. Maintain correct tire
pressure.
pg. 61 Starting the engine
Starting and stopping
1. Fasten the seat belt.WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Move the seat closer if necessary. Refer to section "front seats".
2. Apply the parking brake, if not already set. The gear selector is locked in the (P)ark position (SHIFT LOCK).
3. Without touching the accelerator pedal, turn the ignition key to the starting position. Allow the starter to operate
for up to 5 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts.
4. To release the gear selector from the (P)ark position, the ignition key must be in position II and the brake pedal
must be depressed.
See page 95
for instructions on manually releasing the SHIFTLOCK system.
NOTE: Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be
in the ( P)ark position before the starting key can be removed from the ignition switch.
5. Select the desired gear. The gear engages after a slight delay which is especially noticeable when selecting R.

Check Engine Lamp
If the indicator lamp begins to flash, this is an indication of a fault in the automatic gearbox. The Check Engine
Lamp will also light up if a fault is detected. If the transmission does not shift properly, place the gear selector in
position L. Please contact your Volvo retailer if this occurs.
* These positions always offer the kick-down function.

1) Replace at 105,000 miles (168,000 km)
2) Brake fluid should be changed at owner request every second year or 30,000 miles (48,000 km). The fluid
should be replaced once a year or every 15,000 miles (24,000 km) when driving under extremely hard
conditions (mountain driving, etc.).
3) Rotate tires at owner request.
The following items should be checked weekly by the driver (it takes only a few minutes):
Engine oil level, brake fluid level, radiator coolant level, operation of all lights, horns, windshield wipers, tire
pressure (all five tires), windshield washer fluid level
The following should also be carried out at regular intervals:
Washing (check all drain holes), polishing, cleaning
pg. 108 Servicing
Air cleaner
Replace the air cleaner cartridge with a new one every 30,000 miles (48,000 km). The cartridge should be replaced
more often when driving under dirty and dusty conditions. The filter cannot be cleaned and therefore should always be
replaced with a new one.
Timing belt
For proper functioning of the vehicle and its emission control systems, the timing belt and tensioner must be replaced
every 105,000 miles (168,000 km). Engine damage will occur if the belt fails.
Fuel system cap, tank and lines and connections
The effectiveness of the fuel system to contain hydrocarbons is dependent largely on a leakfree system. Check for
proper sealing of the fuel filler cap which contains "O" ring type seals.
NOTE: If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
Lamp ("Check Engine") may indicate a fault. However, your vehicle's performance will not be affected. Use only
Volvo original or approved fuel filler caps.
Fuel (line) filter
For proper functioning of the vehicle and its emission control systems, the fuel line filter should be replaced at 105,000
miles (168,000 km). The filter is replaced as one complete unit. Replace more frequently if contaminated fuel is
introduced into the tank (or if there is reason to suspect that this has occurred).
