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.

MAINTENANCE AND SERVICE
610Engine oil
For the recommended service intervals and war-
ranties to be applied, an approved engine oil
must be used. Volvo recommends: If the engine oil is not checked regularly and the
level becomes low, this could cause serious
engine damage.
CAUTION
To satisfy the requirements for the engine's
service intervals, all engines are factory-filled
with a specially adapted synthetic engine oil.
Great care has been put into the choice of oil,
with consideration given to service life, starta-
bility, fuel consumption and environmental
impact.
For the recommended service intervals to
apply, an approved engine oil must be used.
Only use the prescribed oil grade to top off or
change the oil. Otherwise, there is a risk of
the vehicle's service life, startability, fuel con-
sumption and environmental impact being
affected.
Failure to use engine oil of the prescribed
grade and viscosity could cause damage to
engine-related components. Volvo Car Corpo-
ration disclaims warranty liability for such type
of damage.
Volvo recommends entrusting oil changes to
an authorized Volvo workshop.
Volvo uses different systems to warn if the oil
level is too low/high or the oil pressure is low. On
engine variants with an oil pressure sensor, awarning symbol is displayed in the instrument
panel when oil pressure is low . On engine
variants with an oil level sensor, the warn-
ing symbol in the instrument panel and display
messages are used to alert the driver. Some
engine variants have both systems. Contact a
Volvo retailer for more information.
Change the engine oil and oil filter according to
the schedule specified in the Warranty and Main-
tenance Records Information booklet. Oils of a
higher grade than that specified may be used. If
the vehicle is driven in adverse conditions, Volvo
recommends using an oil with a higher grade
than that specified.

NOTE
If the conditions for measuring oil level are
not properly fulfilled (time after engine shut-
down, vehicle inclination, ambient tempera-
ture, etc.) the message

Coolant helps keep the combustion engine at
the right operating temperature. The heat trans-
ferred from the engine to the coolant can be
used to warm the passenger compartment.
When refilling coolant, follow the instructions on
the package. Never fill the cooling system with
only water. The risk of freezing is increased with
too low or too high amounts of coolant.
If there is coolant under the vehicle, smoke from
the cooling system, or if more than 2 liters (about
2 quarts) of coolant has been added to the sys-
tem, there could be something wrong with the
cooling system and starting the vehicle could
damage the engine. Call a tow truck and do not
attempt to start the engine.
WARNING The coolant may be very hot. Never unscrew
the cap when the coolant is hot. If coolant
must be filled, unscrew the expansion tank
cap slowly to relieve overpressure. Coolant expansion tank.

Polishing and waxing
Polish and wax the vehicle when the paint is
matte or to provide extra protection. The vehicle
does not need to be polished until it is at least a
year old. However, it can be waxed during the
first year. Do not polish or wax the vehicle in
direct sunlight. The surface of the vehicle should
not be warmer than approximately 45 °C
(113 °F).
• Wash and dry the vehicle very carefully
before polishing or waxing. Remove asphalt
and tar stains with asphalt remover or paint
thinner. More stubborn stains can be
removed with a grinding paste designed for
vehicle paint.
• Use polish first and then liquid or paste wax.
Follow the instructions on the package care-
fully. Many products contain both polish and
wax.
• A wide range of polymer-based waxes can
be purchased today. These waxes are easy to
use and produce a long-lasting, high-gloss
finish that protects the bodywork against oxi-
dation, road dirt and fading.
CAUTION Avoid waxing and polishing plastic and rubber.
If using degreaser on plastic and rubber, only
rub (if necessary) with slight pressure. Use a
soft sponge.
Polishing glossy trim moldings can wear away
or damage the glossy surface layer.
Polish containing abrasives must not be used.
CAUTION
Only use paintwork treatments recommended
by Volvo. Other treatments, such as preserva-
tion, sealing, protection, luster sealing or simi-
lar, could damage the paintwork. Paintwork
damage caused by such treatments are not
covered by Volvo's warranty.

The vehicle should be washed as soon as it
becomes dirty. This makes the vehicle easier to
clean because dirt does not attach as strongly. It
also reduces the risk of scratches and keeps the
vehicle looking new. Wash the vehicle in a car
wash or garage with an oil separator. Use a car
washing detergent.
Hand washingKeep the following points in mind when washing
the vehicle:
• Avoid washing the vehicle in direct sunlight.
This could cause the detergent or wax to dry
out and become abrasive.
• Remove bird droppings from paintwork as
soon as possible. They contain chemicals
that affect and discolor paint very quickly.
Use e.g. soft paper or a sponge soaked in
lots of water. Consult an authorized Volvo
workshop for assistance removing discolora-
tion.
• Hose down the underbody, including the
wheel housings and bumper.
• Hose down the entire vehicle and remove
any loose dirt, droppings etc. to reduce the
risk of scratches from washing. Do not spray
directly onto locks.
• If necessary, use cold degreaser on heavily
soiled surfaces. Note that in such cases the
surfaces must not be hot from the sun.

Cleaning exterior plastic, rubber and
trim components
The vehicle should be washed as soon as it
becomes dirty. This makes the vehicle easier to
clean because dirt does not attach as strongly. It
also reduces the risk of scratches and keeps the
vehicle looking new. Wash the vehicle in a car
wash or garage with an oil separator. Use a car
washing detergent.
Exterior plastic, rubber and trim
components
A special cleaning agent available from Volvo
retailers is recommended for the cleaning and
care of colored plastic parts, rubber and trim
components, e.g. glossy trim. Follow the usage
instructions for the cleaning agent carefully.
Avoid using car washing detergents with a pH
value lower than 3.5 or higher than 11.5. Doing
so could result in the discoloring of anodized alu-
minum surfaces* (as shown in the illustrations
below). Abrasive polishing agents are not recom-
mended for these areas (as shown in the illustra-
tions below). Components that should be washed with a cleaning
product with a pH value between 3.5 and 11.5.
CAUTION
Avoid waxing and polishing plastic and rubber.
If using degreaser on plastic and rubber, only
rub (if necessary) with slight pressure. Use a
soft sponge.
Polishing glossy trim moldings can wear away
or damage the glossy surface layer.
Polish containing abrasives must not be used.
CAUTION Avoid washing the vehicle with cleaner with a
pH value below 3.5 or above 11.5. This could
cause discoloration of anodized aluminum
components like the roof rail and around the
side windows.
Never use metal polishing agent on anodized
aluminum components. This could cause dis-
coloration and destroy the surface treatment.
