Fuel requirements
Fuel requirements
Octane rating: Volvo engines are designed for optimum performance
on unleaded premium gasoline with an octane rating AKI of 91, or
above. AKI (ANTI KNOCK INDEX) is an average of the Research
Octane Number, RON, and the Motor Octane Number, MON. (RON +
MON/2). The minimum octane requirement is AKI 87 (RON 91).

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 lamp)
located on your instrument panel may light. If this occurs, please return
your vehicle to an authorized Volvo retailer for service.Gasoline containing alcohol and ethers

CAUTION:
•Do not refuel with the engine
running*. 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 *.
•Allow for fuel expansion by not
overfilling the tank. Overfilling could
also cause damage to the emission
control systems.
•Avoid spilling gasoline when 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
Warranty.
•Do 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.

* Your car is equipped with an electronic start
inhibitor (immobilizer). The keys you received
with your car are specially coded. The code in
the key is transmitted to an antenna in the
ignition switch where it is compared to the
code stored in the start inhibitor module. The
car can only be started if a properly coded key
is used.
If two of the keys to your car are close
together, e.g., on the same key ring, when you
try to start the car, this could cause interfer-
ence in the immobilizer system and result in
the car not starting. If this should occur,
remove one of the keys from the key ring
before trying to start the car again.

Starting the engine
CAUTION:
•The engine should be idling when you
move the gear selector. Never accelerate
until after you feel the transmission
engage! Accelerating immediately after
selecting a gear will cause harsh engage-
ment and premature transmission wear.
•Selecting P or N when idling at a standstill
for prolonged periods of time will help
prevent overheating of the automatic
transmission fluid.
•Do not race a cold engine immediately
after starting. Oil flow may not reach
some lubrication points fast enough to
prevent engine damage.WARNING!
•Always place the gear selector in Park or
in reverse on models with a manual
transmission, and apply the parking brake
before leaving the vehicle. Never leave the
car 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 monoxide, which is
invisible and odorless but very
poisonous.
•An extra mat on the driver's floor can
cause the accelerator pedal and the clutch
to catch. Check that the movement of the
accelerator pedal and clutch is not
impeded. Not more than one protective
floor covering may be used at one time.

Automatic transmission (Geartronic)
Manual shifting - Geartronic
You can move the gear selector freely between
the (MAN)ual and (D)rive positions while
driving. Gears 2, 3, 4, and 5 have a "lock-up"
function which reduces engine speed and helps
save fuel.

Please refer to the information on page 95.
Sport mode (R-models only)
R-models are equipped with a (S)port button
that can be used to engage/disengage the Sport
shifting mode. An indicator light in the button
will go on when Sport mode is engaged.
With Sport mode engaged, the transmission
will shift up at higher rpm in first and second
gears, and will also shift down at higher rpm
for more immediate engine response during
acceleration and deceleration.

WARNING!
•Driving with the tailgate open: Driving
with the tailgate open could mean that
poisonous exhaust gases enter the
passenger compartment.
If the tailgate must be kept open for any
reason, proceed as follows:
- Close the windows.
- Set the ventilation system to air flow to
floor, windshield and side windows and
blower control to its highest setting.
•Floor mats: 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. Not
more than one protective floor covering
may be used at one time.

Emergency towing
The towing eyelet is located in the tool bag,
under the floor of the cargo area, with the
spare tire. This eyelet must be screwed into the
positions provided on the right sides of either
the front or rear bumper (see illustration). To
attach the towing eyelet:

After the car has been towed, the eyelet should
be removed and returned to the tool bag. Press
the cover back into position.

CAUTION:
•Please check with state and local authori-
ties before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing device,
lighting, etc.
•If the car’s battery is dead, do not attempt
to start the vehicle by pushing or pulling it
as this will damage the three-way catalytic
converter(s). The engine must be jump
started using an auxiliary battery (see page
109).
•If the car is being towed on a flat bed
truck, the towing eyelets must not be used
to secure the car on the flat bed. Consult
the tow truck operator.
WARNING!
•Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but the
brake pedal pressure required is 3 - 4
times above normal and greater steering
effort must be exerted.
•The towing eyelets must not be used for
pulling another vehicle out of a ditch or
for any similar purpose involving severe
strain.
•Do not use the towing eyelets to pull the
car up onto a flat bed tow truck.

WARNING!
•Bumper-attached trailer hitches must not be used on Volvo’s, nor
should safety chains be attached to the bumper.
•Trailer hitches attaching to the vehicle rear axle must not be used.•Never connect a trailer’s hydraulic brake system directly to the
vehicle brake system, nor a trailer’s lighting system directly to the
vehicle lighting system. Consult your nearest authorized Volvo
retailer for correct installation.
•When towing a trailer, the trailer’s safety wire must be correctly
fastened to the hole or hook provided in the trailer hitch on the car.
The safety wire should never be fastened to or wound around the
drawbar ball.
NOTE:
•When parking the car with a trailer on a hill, apply the parking
brake before putting the gear selector in (P)ark or reverse on
models with a manual transmission. Always follow the trailer
manufacturer's recommendations for wheel chocking.
•When starting on a hill, put the gear selector in (D)rive before
releasing the parking brake.
•If you use the manual (Geartronic) shift positions while towing a
trailer, make sure the gear you select does not put too much strain
on the engine (using too high a gear).
•The drawbar assembly/trailer hitch may be certified for trailers that
are heavier than the car is designed to tow. Please adhere to Volvo’s
recommended trailer weights.
* When driving for prolonged periods at temperatures above 86° F
(30° C), the maximum recommended weight is 2000 lbs (900 kg).
When preparing for trailer towing, observe
the following:
Volvo recommends the use of Volvo trailer hitches which are specially
designed for the car.
