Important warnings
Accessory Installation
We strongly recommend that Volvo owners install only genuine, Volvo-approved accessories, and that accessory
installations be performed only by a trained and qualified Volvo service technician.
Genuine Volvo accessories are tested to ensure compatibility with the performance, safety, and emission systems in
your car. Additionally, a trained and qualified Volvo service technician knows where accessories may and may not be
safely installed in your Volvo. In all cases, please consult a trained and qualified Volvo service technician before
installing any accessory in or on your car.
Accessories that have not been approved by Volvo may or may not be specifically tested for compatibility with your
car. Additionally, an inexperienced installer may not be familiar with some of your car's systems.
Any of your car's performance and safety systems could be adversely affected if you install accessories that Volvo
has not tested, or if you allow accessories to be installed by someone unfamiliar with your car.
Damage caused by unapproved or improperly installed accessories may not be covered by your new vehicle
warranty. See your Warranty and Service Records Information booklet for more warranty information. Volvo assumes
no responsibility for death, injury, or expenses that may result from the installation of non-genuine accessories.
Driver distraction
Driver distraction results from driver activities that are not directly related to controlling the vehicle in the driving
environment. Your new Volvo is, or can be, equipped with many feature-rich entertainment and communication
systems. These include hands-free cellular telephones, navigation systems, and multipurpose audio systems. You may
also own other portable electronic devices for your own convenience. When used properly and safely, they enrich the

(may inflate) or disabled (will not inflate).
The OWS will disable (will not inflate) the passenger's side front airbag when:
the front passenger's seat is unoccupied, or has small/medium objects in the front seat,
the system determines that an infant is present in a rear-facing infant seat that is installed according to the
manufacturer's instructions,
the system determines that a small child is present in a forward-facing child restraint that is installed according to
the manufacturer's instructions,
the system determines that a small child is present in a booster seat,
a front passenger takes his/her weight off of the seat for a period of time,
a child or a small person occupies the front passenger's seat.
The OWS uses a PASSENGER AIRBAG OFF indicator lamp which will illuminate and stay on to remind you that the
passenger's side front airbag is disabled. The PASSENGER AIRBAG OFF indicator lamp is located in the overhead
console, near the base of the rearview mirror.
NOTE
When the ignition is switched on, the OWS indicator light will go on for up to 10 seconds while the system performs
a self -diagnostic test.
However, if a fault is detected in the system:
The OWS indicator light will stay on

1. Malfunction indicator light
As you drive, a computer called On-Board Diagnostics II (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 vehicle checked by a trained and qualified Volvo service technician 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 controls, and drivability. Extended driving without
correcting the cause could even damage other components in your car.
NOTE
Canadian models are equipped with the second symbol.
2. 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).

Audible/visual alarm signal

When switching to higher octane fuel or changing gasoline brands, it may be necessary to fill the tank more than
once before a difference in engine operation is noticeable.
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 drivability 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
Ethyl alcohol, or "Gasohol". Ethers - MTBE: Fuels containing up to 15% MTBE may be used.
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
