goal. In addition to continuous environmentalrefinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles.
When you drive a Volvo, you become our partnerin the work to lessen the vehicle's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
•Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
•Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
•Drive at a constant speed whenever possible.
•See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
•Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
•When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.

Twin Engine vehicles
•If possible, precondition the vehicle with thecharging cable before driving.
•If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.
•Choose the Pure drive mode to help mini-mize electric power consumption.
•In hilly terrain, put the gear selector in modeB to utilize the electric motor's braking func-tion when the accelerator pedal is released.This helps charge the hybrid battery.

seated occupant and determine if the passeng-er's side front airbag should be enabled (mayinflate) or disabled (will not inflate).
The OWS will disable (will not inflate) the pas-senger's side front airbag when:
•the front passenger's seat is unoccupied, orhas small/medium objects in the front seat,
•the system determines that an infant is pres-ent in a rear-facing infant seat that is instal-led according to the manufacturer's instruc-tions,
•the system determines that a small child ispresent in a forward-facing child restraintthat is installed according to the manufactur-er's instructions,
•the system determines that a small child ispresent in a booster seat,
•a front passenger takes his/her weight off ofthe seat for a period of time,
•a child or a small person occupies the frontpassenger's seat.
The OWS uses a PASSENGER AIRBAG OFFindicator lamp which will illuminate and stay on toremind you that the passenger's side front airbagis disabled. The PASSENGER AIRBAG OFF indi-cator lamp is located in the overhead console,near the base of the rearview mirror.

NOTE
When the ignition is switched on, the OWSindicator light will illuminate for several sec-onds while the system performs a self-diag-nostic test.
However, if a fault is detected in the system:
•The OWS indicator light will stay on
•The SRS warning light will come on and stayon and a text message will be displayed.

WARNING
If a fault in the system is detected and indi-cated as described, be aware that the pas-senger's side front airbag will not deploy inthe event of a collision. In this case, the SRSsystem and Occupant Weight Sensor shouldbe inspected by a trained and qualified Volvoservice technician as soon as possible.

Charging the hybrid battery
In addition to the conventional fuel tank, your
vehicle is also equipped with a rechargeable
lithium-ion hybrid battery.
The hybrid battery can be recharged using the
charging cable stored in a storage space in the
cargo compartment.
WARNING
The hybrid electrical system in your vehicle
uses high voltage electrical current. Any dam-
age to this system or to the hybrid battery
may result in the danger of overheating, fire,
or serious injury. If the vehicle is involved in a
collision or subjected to flooding, fire, etc.,
have it inspected by a trained and qualified
Volvo service technician. Prior to this inspec-
tion, the vehicle should be parked outdoors at
a safe distance from any building or poten-
tially flammable materials.
The hybrid battery's charging time depends on
the charging current used.
NOTE The capacity of the hybrid battery diminishes
somewhat with age and use, which could
result in increased use of the gasoline engine
and consequently, slightly higher fuel con-
sumption.
WARNING If the hybrid battery needs to be replaced, this
may only be done by Volvo retailer or author-
ized Volvo workshop.
Charging cable handle and charging socket.
Charging status is indicated in three ways:
• The indicator lights in the charging module
(the unit connected to the wall outlet).
• Indicator light in the vehicle's charging
socket.
• Images and text in the instrument panel.
The hybrid battery's charging process also
charges the vehicle's start battery.
If the hybrid battery's temperature is below
-10 ºC (14 ºF) or above 40 ºC (104 ºF), some of
the vehicle's functions may be reduced or not
available at all. The electric motor cannot be used if the battery's
temperature is too low or too high. If the PURE
drive mode is selected, the gasoline engine will
start.
Charging using the gasoline engine
The vehicle generates electrical current to charge the
battery, e.g. when the driver lightly presses the brake
pedal or when engine braking is used on downgrades.
The vehicle can also generate current to the
hybrid battery to charge it.
• The hybrid battery can also be recharged by
lightly depressing the brake pedal, i.e. during
light braking. This converts the vehicle's
kinetic energy to electrical energy, which is
used to charge the hybrid battery.
• In gear position B, the electric motor brakes
the vehicle when the accelerator pedal is

Charging status in the charging
cable's charging module
The red and blue lights in the charging module
indicate the status of ongoing and completed
charging. Charge module: 1. Red warning light, 2. Blue status indi-
cator
When the charge module is initially plugged into
a wall outlet, the red warning light will flash once
to indicate that a startup safety check has been
performed. When the safety check has been
completed, the blue status indicator will glow
steadily and the red warning light will be off. The
charger is now ready to be used. If the red warn-
ing light continues to flash or glows steadily, a
fault has been detected and the charger will not
deliver power to the vehicle. Contact a Volvo
retailer or a certified Volvo service technician. When the charging cable is connected to the
vehicle's charging socket, the blue light will flash
once.

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 light) located on your instrument
panel may light. If this occurs, please return
your vehicle to a trained and qualified Volvo
service technician 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 permits the use of the following "oxygen-
ated" fuels. However, the specified octane ratings
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/ETBE: Fuels containing up to
15% MTBE/ETBE may be used.
MethanolDo 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.

Tires with tread designed to roll in only one
direction are marked with an arrow on the side-
wall. The arrow shows the tire's direction of rotation.
• The tire should maintain the same direction
of rotation throughout its service life.
• Tires should only be moved between the
front and back, never from right to left or vice
versa.
• Incorrectly mounted tires impair the vehicle's
braking properties and ability to force aside
rain, snow and slush.
• The tires with the most tread should always
be mounted on the rear wheels to help
reduce the risk of skidding.
NOTE Use tires of the same type, dimensions and
make (manufacturer) on each axle.
