Fuel requirements
06``129 Octane rating
Minimum octane
G028920
Typical pump octane labelVolvo recommends premium for best perform-
ance, but using 87 octane or above will not
affect engine reliability.
Volvo engines are designed to achieve rated
horsepower, torque, and fuel economy per-
formance using premium 91 octane fuel.Demanding drivingIn demanding driving conditions, such as oper-
ating the vehicle in hot weather, towing a trailer,
or driving for extended periods at higher alti-
tudes than normal, it may be advisable to
switch to higher octane fuel (91 or higher) or to
change gasoline brands to fully utilize yourengine's capacity, and for the smoothest pos-
sible operation.
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 as a
knock inhibitor, and do not use lead additives.
Besides damaging the exhaust emission con-
trol 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
precautions. 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, thicken-
ers, 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
Carbon 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
compartment is ventilated, and immediately
return the vehicle to a trained and qualified
Volvo service technician for correction.

WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment.•
If the tailgate must be kept open for any
reason, proceed as follows:
•
Close the windows
•
Set the ventilation system control to air
flow to floor, windshield and side win-
dows and blower control to its highest
setting.
Weight distribution affects handlingAt the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend.
This ensures good stability and reduces the
risk of rear wheel skid. Remember that these
properties can alter with the vehicle load.
The heavier the load in the cargo area, the less
the tendency to understeer.Handling, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommendedpressure according to the vehicle load. See
"Tire pressure" section.
Loads should be distributed so that capacity
weight or maximum permissible axle loads are
not exceeded.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:•
When the engine is not running, avoid turn-
ing the ignition key to position II (see
page 135). Many electrical systems (the
audio system, the optional infotainment/
navigation systems, power windows, etc)
will function with the ignition key in position
I. This position reduces drain on the bat-
tery.
•
Please keep in mind that using systems,
accessories, etc that consume a great deal
of current when the engine is not running
could result in the battery being completely
drained.NOTE
A warning message will be displayed in the
text window in the instrument panel when
the battery charge is low.

06 Starting and driving
Refueling
06``131 Fuel filler door
G027073
The fuel filler cap can be placed on the hook on
the fuel filler door while refuelingPress the button on the light switch panel (see
the illustration on page 63) when the vehicle is
at a standstill to unlock the fuel filler door.
Please note that the fuel filler door will remain
unlocked until the vehicle begins to move for-
ward. An audible click will be heard when the
fuel filler door relocks.
If you intend to leave your vehicle while it is
being refueled, this feature enables you to lock
the doors/tailgate while leaving the fuel filler
door unlocked.You can also keep the vehicle locked if you
remain inside it during refueling. The central
locking button does not lock the fuel filler door.
Be sure the fuel filler door is not obstructed and
is completely closed after refueling.
Open the fuel filler cap slowly during hot
weather.
NOTE
During a transitional period, a small number
of service stations may still have fuel noz-
zles that are not compatible with the fuel
filler neck on vehicles equipped with the
evaporative control system.RefuelingThe fuel tank is designed to accommodate
possible expansion of the fuel in hot weather.
See page 265 for fuel tank volume. Be aware
that the "usable" tank capacity will be some-
what less than the specified maximum. When
the fuel level is low, such factors as ambient
temperature, the fuel's "Reid vapor pressure"
characteristics, and terrain can affect the fuel
pump's ability to supply the engine with an
adequate supply of fuel. Therefore, it is advis-
able to refuel as soon as possible when theneedle nears the red zone, or when the fuel
warning light comes on.
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 gasoline fumes, resulting in fire and
injury.

06 Starting and drivingRefueling
06132
CAUTION
•
Do not refuel with the engine running
1.
Turn the ignition off or to position I. If the
ignition is on, an incorrect reading could
occur in the fuel gauge.
•
After refueling, close the fuel filler cap
by turning it clockwise until it clicks into
place
1.
•
Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much
fuel in the tank in hot weather conditions
can cause the fuel to overflow. Overfill-
ing could also cause damage to the
emission control systems.
•
Avoid spilling gasoline during refueling.
In addition to causing damage to the
environment, gasolines containing
alcohol can cause damage to painted
surfaces, which may not be covered
under the New Vehicle Limited War-
ranty.
•
Do not use gasolines containing meth-
anol (methyl alcohol, wood alcohol).
This practice can result in vehicle per-
formance deterioration and can dam-
age critical parts in the fuel system.
Such damage may not be covered
under the New Vehicle Limited War-
ranty.
1If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator lamp) may indicate a fault. However, your vehicle's
performance will not be affected. Use only Volvo original or approved fuel filler caps.

06``133 Starting the engine
WARNING
Before starting, check that the seat, steering
wheel and mirrors are adjusted properly.
Make sure the brake pedal can be
depressed completely. Adjust the seat if
necessary, see page 100.1. Fasten the seat belt.
2. Apply the parking brake (hand brake) if not
already set. The gear selector is locked in
theP position (SHIFTLOCK).
3. Without touching the accelerator pedal,
turn the ignition key
1 to the starting posi-
tion. Allow the starter to operate for up to
10 seconds. Release the key as soon as
the engine starts
2. If the engine fails to
start, repeat this step.
NOTE
•
If the key blade section of the remote is
not fully folded out when starting the
vehicle, the immobilizer function may
make it impossible to start the engine.
•
After a cold start, idle speed may be
noticeably higher than normal for a
short period. This is done to help bring
components in the emission control
system to their normal operating tem-
perature as quickly as possible, which
enables them to control emissions and
help reduce the vehicle's impact on the
environment.
•
To release the gear selector from the P
(Park) position, the engine must be run-
ning (or the ignition key must be in posi-
tionII) and the brake pedal must be
depressed.
•
Select the desired gear. The gear
engages after a very slight delay which
is especially noticeable when selecting
R.
NOTE
Your vehicle is equipped with a KEYLOCK
system. When the engine is switched off,
the gear selector must be in the P position
before the key can be removed from the
ignition switch.
When starting in cold weather, the trans-
mission may shift up at slightly higher
engine speeds than normal until the auto-
matic transmission fluid reaches normal
operating temperature.
NOTE
Do not race a cold engine immediately after
starting. Oil flow may not reach some lubri-
cation points fast enough to prevent engine
damage.
WARNING
An extra mat on the driver's floor can cause
the accelerator pedal to catch. Check that
the movement of the accelerator pedal is
not impeded. No more than one protective
floor covering may be used at one time.
1If two of the keys to your vehicle are close together, e.g. on the same key ring when you try to start the vehicle, this could cause interference in the immobilizer system and result in the vehicle not
starting. If this should occur, remove one of the keys from the key ring before trying to start the vehicle again.2On vehicles equipped with the autostart feature, release the key immediately. See also page 135.

WARNING
Always place the gear selector in Park and
apply the parking brake before leaving the
vehicle. Never leave the vehicle unattended
with the engine running.•
Always open garage doors fully before
starting the engine inside a garage to
ensure adequate ventilation. The
exhaust gases contain carbon monox-
ide, which is invisible and odorless but
very poisonous.CAUTION
Automatic transmission•
The engine should be idling when you
move the gear selector. Never acceler-
ate until after you feel the transmission
engage! Accelerating immediately after
selecting a gear will cause harsh
engagement and premature transmis-
sion wear.
•
SelectingP or N when idling at a stand-
still for prolonged periods of time will
help prevent overheating of the auto-
matic transmission fluid.

Turn the key to position IIIand release it. The
starter motor will then operate automatically
(for up to ten seconds) until the engine starts.Steering wheel lockThe steering wheel lock might be under tension
when the vehicle is parked.
Turn the steering wheel slightly to free the igni-
tion key.
In order to help reduce vehicle theft, make sure
the steering wheel lock is engaged before leav-
ing the vehicle.
WARNING
Never switch off the ignition (turn the ignition
key to position 0) or remove the key from the
ignition switch while the vehicle is in motion.
This could cause the steering wheel to lock,
which would make the vehicle impossible to
steer.

06 Starting and drivingEconomical driving
06136
Economical driving conserves natural
resourcesBetter driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions. Observe the fol-
lowing rules:•
Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
•
Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•
Drive carefully and avoid rapid acceleration
and hard braking.
•
Use the transmission's D (Drive) position
as often as possible and avoid using "kick-
down" to help improve fuel economy.
•
Do not exceed posted speed limits.
•
Avoid carrying unnecessary items (extra
load) in the vehicle.
•
Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
•
Remove snow tires when threat of snow or
ice has ended.
•
Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
•
At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
•
Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
•
Dirty air cleaner
•
Dirty engine oil and clogged oil filter
•
Dragging brakes
•
Incorrect front end alignment.
Some of the above mentioned items and others
are checked at the standard Maintenance
Service intervals.CAUTION
Drive slowly and carefully if going through
standing water (i.e. flooded roadways, etc.).
Damage to the engine could result if excess
water is drawn in through the air intake sys-
tem. Never drive the vehicle in water deeper
than 18 inches (48 cm).
