This means that when you switch off the ignition, the gear selector must  be  in the (P)ark position before the key  can be
removed from  the ignition switch.
Anti-lock Brake System (ABS)
The ABS  system in your car performs a  self -diagnostic test when the vehicle first reaches the 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.
Fuel filler door
Press the button on the light switch panel (see on page 32
) when the car is at a  standstill to unlock the fuel filler  door.
Please note that the fuel filler  door will remain unlocked until the car is driven again at a  a  speed of over
approximately 5 mph (8km/h). An audible  click  will be  heard when the fuel filler  door relocks.
Fuel filler cap
After refueling, close the fuel filler  cap by turning it clockwise until it clicks into place. If this  cap is not closed tightly
or if the engine is running when the car is refueled, the Malfunction  Indicator Lamp ("Check Engine" light) may

A self -diagnostic system incorporated in the sensor monitors the SRS. This system does not, however,  monitor the
Side Impact Protection System  (SIPS) airbags. If a  fault is detected, the 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 key  is turned to positions I, II or III and  should go out after 7 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 igniters
WARNING!
Never  drive an  SRS equipped car with your hands on the steering wheel pad  / airbag housing.
No objects, accessory  equipment or stickers may be  placed on, attached to or installed near the SRS cover in the
center  of the steering wheel, the SRS cover above the glove compartment or the area affected by airbag deployment.
If the SRS warning light stays on after the engine has started or if it comes on while you are driving, drive the car
to the nearest authorized Volvo retailer for inspection as soon as possible.
There is no maintenance to perform on the SRS yourself. The month and  year shown on the decal on the door pillar
indicate when you should contact your Volvo retailer for specific servicing or replacement  of airbags and  seat belt
tensioners. This service must  be  performed by an  authorized Volvo retailer.
Should you have any  questions about the SRS system, please contact your authorized Volvo retailer or Volvo

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.
Brake failure warning light
If the light  comes on while driving or  braking, stop immediately, open the hood and check  the brake fluid  level
in the reservoir.  See  page 130 
for reservoir position and  page 133 for instructions.
Canadian models are equipped with this  warning light: 
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 130
. 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.

Rear fog light
This light indicates that the rear fog light is on.
Malfunction indicator lamp
On-Board Diagnostic II (OBDII): As you drive, a  computer called "OBDII" monitors your car's engine, transmission,
electrical and  emission systems. The CHECK ENGINE light will light up if the computer senses a  condition that
potentially may need correcting. When this  happens, please have your car checked by a  Volvo retailer as soon as
possible.
A CHECK ENGINE light may have many causes. Sometimes,  you may not notice  a  change in your car's behavior.
Even so, an  uncorrected condition could hurt fuel economy, emission cleanliness, and  driveability. Extended driving
without correcting the cause could even damage other components in your car.
Canadian models are equipped with this  warning light: 
NOTE : If the fuel filler  cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction
Indicator Lamp may indicate a  fault. However, your vehicle's performance will not be  affected. Use only Volvo
original or approved fuel filler  caps.
Anti-lock Brake System ABS
If the warning light comes on, there is a  malfunction of the ABS  system (the standard braking system will still
function). The vehicle should be  driven to a  Volvo retailer for inspection. See  page 19 
for additional information.

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 gasoline containing deposit control additives. These additives have shown to be
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.
CAUTION! 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.
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 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 an  authorized Volvo retailer for service.
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. 
pg. 81 Fuel  requirements
Carbon Monoxide - Important  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.

additional information.
* 18.5 US gals (70 liters) on V70 AWD, V70 XC and  V70 with non-turbo engine.
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 *.
Allow for fuel expansion by not overfilling the tank. Overfilling  could also cause damage to the emission control
systems.
Avoid spilling  gasoline when refueling. In addition to causing damage to the environment, 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.
* If the fuel filler  cap  is not closed tightly or if the engine is running when the car is refueled, the Check Engine light

Volvo original or approved fuel filler  caps.  
pg. 83 Starting the engine
Starting the engine
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and  mirrors  adjusted properly. Make sure the brake pedal can be
depressed  completely.  Adjust the seat if necessary.  See  page 52.
2. Apply the parking brake, if not already  set. The gear selector (automatic transmission) is locked in the (P)ark
position (SHIFT-LOCK). Manual transmission: the clutch  must  be  fully depressed.
3. Without touching the accelerator  pedal, turn the ignition key*  to the starting position. Allow the starter to operate  for
up to 10 seconds. Release the key  as soon as the engine starts. If the engine fails to start, repeat  this  step.
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 engine must  be  running (or the ignition key  must  be  in
position II) and  the brake pedal must  be  depressed.
5. Select  the desired gear. The gear engages after a  very slight delay which  is especially noticeable when selecting R.
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 key  can be  removed from  the ignition switch.
When starting in cold weather, the transmission may shift up at slightly  higher engine speeds than normal until the
automatic  transmission fluid reaches normal operating temperature.
CAUTION:

W Winter/Wet driving mode -enhanced vehicle  traction
Mode W  will function only if the gear selector is in the (D)rive  position.
Press the button at the base of the gear selector to engage/disengage this  driving mode (see illustration).
An LED  in the button will light up to indicate that W is engaged and  this  will also be  displayed in the instrument
panel (see page 25
).
This mode may be  selected for starting/ moving off on slippery roads. 
pg. 89 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 (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  also fuel consumption.
Avoid using automatic  transmission kickdown  feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the conditioner's compressor places an
additional load on the engine. However, at higher 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:
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.
