.TOP TIER Detergent GasolineVolvo endorses the use of "TOP TIER Detergent
Gasoline" where available to help maintain
engine performance and reliability. TOP TIER
Detergent Gasoline meets a new standard jointly
established by leading automotive manufactures
to meet the needs of today's advanced engines.
Qualifying gasoline retailers (stations) will, in
most cases, identify their gasoline as having met
the "TOP TIER Detergent Gasoline" standards.
NOTE Information about TOP TIER Detergent Gaso-
line is available at www.toptiergas.com.
NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticeable.
Fuel FormulationsDo not use gasoline that contains lead or manga-
nese as a knock inhibitor, and do not use lead
additives. Besides damaging the exhaust emis-
sion control systems on your vehicle, lead has
been strongly linked to certain forms of cancer.Many fuels contain benzene as a solvent.
Unburned benzene has been strongly linked to
certain forms of cancer. If you live in an area
where you must fill your own gas tank, take pre-
cautions. These may include:
•
standing upwind away from the filler nozzle
while refueling
• refueling only at gas stations with vapor
recovery systems that fully seal the mouth of
the filler neck during refueling
• wearing neoprene gloves while handling a
fuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze during
winter months, do not add solvents, thickeners, or
other store-bought additives to your vehicle's
fuel, cooling, or lubricating systems. Overuse may
damage your engine, and some of these additives
contain organically volatile chemicals. Do not
needlessly expose yourself to these chemicals.
WARNING Never carry a cell phone that is switched on
while refueling your vehicle. If the phone rings,
this may cause a spark that could ignite gaso-
line fumes, resulting in fire and injury.

AKI (Anti Knock Index) is an average value of RON (Research Octane Nu\
mber) and MON (Motor Octane Number) - (RON)+(MON)/2

WARNINGCarbon 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 com-
partment is ventilated, and immediately return
the vehicle to a trained and qualified Volvo
service technician for correction.
Demanding drivingIn demanding driving conditions, e.g. when driving
in a hot climates, driving with a trailer or driving
for longer periods at higher altitudes (mountain
landscapes) than normal, it is recommended
switching to a higher octane fuel than AKI 91
6
or
changing gasoline brand to take full advantage of
your car's engine capacity and obtain the opti-
mum driving force.

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.

Battery drain
The electrical functions in the vehicle drain the
battery to varying degrees. Avoid using ignition
mode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain
power from the electrical system. Do not use
functions that use a lot of electrical current when
the engine is turned off. Examples of such func-
tions are: • blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message is
shown in the driver display. The vehicle's energy-
saving function will then turn off or reduce certain
functions, such as the blower and/or the audio
system.
– Charge the battery by starting the engine
and let it run for at least 15 minutes (driving
charges the battery faster than letting the
engine idle).

CAUTION
The charging point of the vehicle is only
intended for jump starting the vehicle in ques-
tion. The charging point is not intended for
jump-starting another vehicle. Using the
charging point to start another vehicle could
cause a fuse to blow, which would cause the

ment panel. Volvo recommends contacting an

stop. Fasten the eyelet securing by, for exam-
ple, inserting a lug wrench* through it and
using this as a lever.
CAUTION It is important that the towing eye is screwed
in securely as far as possible.

This section refers to transporting the vehicle
with a tow truck or similar vehicle. Call a professional towing service for assistance.
In certain conditions, the towing eyelet can be
used to pull the vehicle onto a flatbed tow truck.
CAUTION Note that vehicles with Twin Engine must
always be towed raised with all wheels on the
tow truck.
For vehicles equipped with leveling control*:
If the vehicle is equipped with pneumatic suspen-
sion, this feature must be turned off before the
vehicle is lifted onto a tow truck. Turning off the
function in the center display.
1. Tap Settings in the Top view.
2.

Tap My Car Parking Brake and
Suspension .
3. Select Disable Leveling Control.
The vehicle's location and ground clearance
determine if it can be lifted onto a tow truck. If
the incline of the tow truck is too steep or if the
ground clearance under the vehicle is insufficient,
attempting to pull it up may result in damage. In
this case, the vehicle should only be lifted with
the tow truck's lifting equipment.
