WARNING
California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To mini-
mize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, serv-
ice your vehicle in a well ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more infor-
mation go to www.P65Warnings.ca.gov/
passenger-vehicle.

Fuel (p. 476) Fuel
Volvo recommends the use of detergent gaso-
line to control engine deposits.
Deposit control gasoline (gasoline with
detergent additives)
Detergent gasoline is effective in keeping injec-
tors 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.
NOTE Volvo recommends not using external fuel
injector cleaning systems, e.g. do not add
detergent additives to gasoline before or after
refueling.
Unleaded fuelAll Volvo vehicles have a three-way catalytic con-
verter and must only use unleaded gasoline. US
and Canadian regulations require that pumps
delivering unleaded gasoline are labeled
"UNLEADED". Only the nozzles of these pumps
will fit in your vehicle's fuel filler inlet. It is unlaw-
ful to dispense leaded fuel into a vehicle labeled
"unleaded gasoline only". Leaded gasoline dam-
ages the three-way catalytic converter and the
heated oxygen sensor system. Repeated use of
leaded gasoline will lessen the effectiveness ofthe 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.

Emission controls
Three-way catalytic converter

Keep your engine properly tuned. Certain
engine malfunctions, particularly involving the
electrical, fuel or distributor ignition systems,
may cause unusually high three-way catalytic
converter temperatures. Do not continue to
operate your vehicle if you detect engine
misfire, noticeable loss of power or other
unusual operating conditions, such as engine
overheating or backfiring. A properly tuned
engine will help avoid malfunctions that
could damage the three-way catalytic con-
verter.
Do not park your vehicle over combustible
materials, such as grass or leaves, which can
come into contact with the hot exhaust sys-
tem and cause such materials to ignite under
certain wind and weather conditions.
Excessive starter cranking (in excess of one
minute), or an intermittently firing or flooded
engine can cause three-way catalytic con-
verter or exhaust system overheating.
Remember that tampering or unauthorized
modifications to the engine, the Engine Con-
trol Module, or the vehicle may be illegal and
can cause three-way catalytic converter or
exhaust system overheating. This includes:
altering fuel injection settings or compo-
nents, altering emission system components or location or removing components, and/or
repeated use of leaded fuel.NOTE Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen
content of the exhaust gases. Readings are fed
into a control module that continuously monitors
engine functions and controls fuel injection. The
ratio of fuel to air into the engine is continuously
adjusted for efficient combustion to help reduce
harmful emissions.

Fuel (p. 476) Overheating of engine and
transmission
In demanding driving conditions, such as driving
in mountainous areas or hot weather, there is a
risk of the engine or transmission overheating,
especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in front
of the grille when driving in hot weather.
If the temperature in the engine's cooling
system becomes too high, a warning symbol
will appear in the instrument panel along with
the message Engine temperature High
temperature Stop safely. Pull over to a safe location and let the engine idle for a few
minutes to cool down.
If the message

Engine 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.

It may be necessary to top up engine oil between
regularly scheduled services.
No action is necessary with regard to engine oil
level until a message appears in the instrument
panel.
WARNING If this symbol is shown together
with the message
Engine oil level
Service required, visit a workshop – an authorized Volvo workshop is
recommended. The oil level may be too high.
CAUTION If this symbol is shown together
with a message about low oil level,
for example
Engine oil level low
Refill 1 liter, fill only with the indi-
cated volume, e.g. 1 liter (1 quart).
WARNING Do not spill oil on the hot exhaust pipes as
this could cause a fire.
Viewing oil level in the center displayThe oil level can be viewed using the electronic
oil level gauge in the center display once the
vehicle has been started. The oil level should be
checked regularly.
1.
Open the Car Status app from App view in
the center display.
2. Tap Status to display the oil level. Oil level graphic in the center display.NOTE
The system cannot directly detect changes
when the oil is filled or drained. The vehicle
must have been driven approximately 30 km
(20 miles) and have been stationary
5 minutes on a level surface and with the
engine off before the correct oil level will be
displayed.
