Leveling control
*
and suspension
Self-leveling and suspension functions are
controlled automatically.
Rear leveling control keeps the rear section of
the vehicle at the same height regardless of
load. Leveling control may also remain active
when the vehicle is parked.
Shock absorbers (Four-C)
On vehicles equipped with Four-C, the shock
absorbers are adapted to the selected drive
mode and the current vehicle speed. The
shock absorbers are normally set to help opti-
mize comfort and are adjusted continuously
according to the road surface and the vehicle's
acceleration, braking and cornering.
Transporting
When transporting the vehicle on a ferry, train
or truck, only secure (lash) the vehicle around
the tires, not using any other parts of the chas-
sis. Changes in the pneumatic suspension
may occur during transport, which could
adversely affect the lashing and result in dam-
age.

Economical driving
A more economical driving style can help
lower fuel consumption.
Before driving
•
If possible, precondition the vehicle before
driving.
•
If preconditioning is not possible when it
is cold outside, use seat and steering
wheel heating first. Avoid heating the
entire passenger compartment to reduce
the amount of current being taken from
the start battery.
•
Avoid using idling to warm up the vehicle
before driving.
•
The type of tires and inflation pressure
used could affect energy consumption –
consult an authorized Volvo retailer for
advice on suitable tires.
•
Remove unnecessary items from the vehi-
cle - the heavier the load, the higher the
fuel consumption.
While driving
•
Activate
Eco
drive mode.
•
Use gear selector position
D
as often as
possible.
•
When using manual gear shifting, drive
using the highest possible gear. Use the
gear indicator
14
.
•
Maintain a steady speed and a generous
following distance to traffic ahead to mini-
mize braking. Use engine braking if possi-
ble.
•
Higher speeds increase energy consump-
tion because air resistance increases with
speed.
•
In a cold climate, reduce heating of the
windshield/rear window, mirrors, seats
and the steering wheel.
•
Avoid driving with the windows open.
•
Do not use the accelerator pedal to keep
the vehicle stationary on an uphill gradi-
ent. Instead, activate the auto-hold brake
function at a standstill.
•
Use trip data to see current fuel consump-
tion.
WARNING
Never turn off the engine while the vehicle
is moving, e.g. when driving downhill. This
deactivates certain important systems
such as power steering and brakes.

Winter driving
It is important to check the vehicle before
driving in cold/snowy conditions to make
sure it can be driven safely.
Before the cold season arrives:
•
Make sure the engine coolant contains
50% antifreeze. This mixture helps pro-
tect the engine from frost erosion down to
approx. –35 °C (–31 °F). Do not mix dif-
ferent types of antifreeze as this could
pose a health risk.
•
Keep the fuel tank well filled to prevent
condensation from forming.
•
Check the viscosity of the engine oil. Oil
with low viscosity (thinner oil) improves
cold-weather starting and reduces fuel
consumption when driving with a cold
engine.
•
Check the condition and charge level of
the start battery. Cold weather places
greater demands on the start battery and
reduces its capacity.
•
Use washer fluid containing antifreeze to
help prevent ice from forming in the
washer fluid reservoir.
See separate section for engine oil recommen-
dations.

Slippery driving conditions
To help optimize traction and roadholding,
Volvo recommends using snow tires on all
wheels whenever there is a risk of snow or ice
on the road.
Certain countries require use of winter tires
by law. Not all countries permit the use of
studded tires.
Practice driving on slippery surfaces under
controlled conditions to learn how the vehicle
reacts.

Driving through standing water
It may be necessary to drive the vehicle
through standing water e.g. deep puddles or
flooding on the road. This must be done with
great caution.
The vehicle can be driven through water up to
a depth of 25 cm (9 in) at no more than walk-
ing speed. Be particularly careful when driving
through flowing water.
When driving through standing water, drive
slowly and do not stop the vehicle. When you
have passed the water, press lightly on the
brake pedal and check that the brakes are
functioning properly. Water, mud, slush, etc.
can make the brake linings slippery, resulting
in delayed braking effect.
•
If the vehicle is equipped with contacts for
an electric heater or trailer coupling, clean
these after driving in water or mud.
•
Do not allow the vehicle to stand in water
up to the sills any longer than absolutely
necessary. This could result in electrical
malfunctions.
•
Engine damage could occur if water
enters the air cleaner.
•
If water enters the transmission, the
lubricating ability of the oils is reduced
and the service life of these systems is
shortened.
•
Damage to any component, engine,
transmission, turbocharger, differential
or its internal components caused by
flooding, vapor lock or insufficient oil is
not covered under warranty.
•
If the engine stalls while the vehicle is
in water, do not attempt to restart it.
Have the vehicle towed out of the
water to a workshop. An authorized
Volvo workshop is recommended. Risk
of engine failure.
Because it can be difficult to determine the
water depth, Volvo recommends not driv-
ing through standing or running water. The
driver is always responsible for operating
the vehicle in a safe manner and adhering
to all applicable laws and regulations.

station
It is important to insert the pump's nozzle past both
of the two flaps in the fuel filler pipe before beginning
fueling.
Instructions for fueling:
1. Turn off the engine and open the fuel filler
door.
2. Select a fuel approved for use in the vehi-
cle. For more information on approved
fuels, see the section on “Fuel”.
3. Insert the pump's nozzle into the fuel filler
pipe's opening. There are two flaps just
inside the fuel filler pipe and the pump's
nozzle must push both of these flaps open
before fuel can be added.
4. Avoid overfilling the tank. Do not press the
handle on the filler nozzle again after it has
initially stopped pumping.
> The fuel tank is now filled.
An over-full tank may overflow in hot
weather.
Avoid spilling gasoline during refueling. In
addition to causing damage to the environ-
ment, gasolines containing alcohol can
cause damage to painted surfaces, which
may not be covered under the New Vehicle
Limited Warranty.
Refueling from a fuel container
When filling from a fuel container, use the fun-
nel provided in a foam block under the floor
hatch in the cargo compartment.

WARNING
California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemi-
cals including engine exhaust, carbon mon-
oxide, phthalates, and lead, which are
known to the State of California to cause
cancer and birth defects or other reproduc-
tive harm. To minimize exposure, avoid
breathing exhaust, do not idle the engine
except as necessary, service your vehicle in
a well ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to

Fuel
Volvo recommends the use of detergent gas-
oline to control engine deposits.
Deposit control gasoline (gasoline
with detergent additives)
Detergent gasoline is effective in keeping
injectors 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 serv-
ice station operator.
Volvo recommends not using external fuel
injector cleaning systems, e.g. do not add
detergent additives to gasoline before or
after refueling.
Unleaded fuel
All Volvo vehicles have a three-way catalytic
converter and must only use unleaded gaso-
line. 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 unlawful to dispense leaded fuel into
a vehicle labeled "unleaded gasoline only".
Leaded gasoline damages the three-way cata-
lytic converter and the heated oxygen sensor
system. Repeated use of leaded gasoline will
lessen the effectiveness of the emission con-
trol 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 emis-
sion test failure for misfueled vehicles.
Some U.S. and Canadian gasolines contain
an octane enhancing additive called
methyl-cyclopentadienyl manganese tricar-
bonyl (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 techni-
cian 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 indi-
cating 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
-------------------------------------------------------------------------------------------------------------------------------------------------------------
||
STARTING AND DRIVING
434
meet seasonal air quality standards, some
areas require the use of "oxygenated" fuel.
Volvo permits the use of the following "oxy-
genated" fuels. However, the specified octane
ratings must still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred to
as Ethyl alcohol, or "Gasohol".
Ethers - MTBE/ETBE: Fuels containing up to
22% MTBE/ETBE by volume may be used.
Methanol
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 sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.

TOP TIER Detergent Gasoline
Volvo endorses the use of "TOP TIER Deter-
gent Gasoline" where available to help main-
tain engine performance and reliability. TOP
TIER Detergent Gasoline meets a new stand-
ard jointly established by leading automotive
manufactures to meet the needs of today's
advanced engines. Qualifying gasoline retail-
ers (stations) will, in most cases, identify their
gasoline as having met the "TOP TIER Deter-
gent Gasoline" standards.

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 noticea-
ble.
Fuel Formulations
Do not use gasoline that contains lead or man-
ganese as a knock inhibitor, and do not use
lead additives. Besides damaging the exhaust
emission 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
precautions. These may include:
•
standing upwind away from the filler noz-
zle 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 Additives
With the exception of gas line antifreeze dur-
ing winter months, do not add solvents, thick-
eners, 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 gasoline fumes, resulting in fire
and injury.
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 immedi-
ately return the vehicle to a trained and
qualified Volvo service technician for cor-
rection.
Demanding driving
In demanding driving conditions, such as
when towing a trailer or driving in hot weather
or for prolonged periods at high altitudes, it
may be a good idea to switch to a higher-
octane fuel (AKI
16
91 or higher) or to switch to
another brand of gasoline in order to fully uti-
lize the vehicle's engine capacity and optimize
traction.

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 condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help
avoid malfunctions that could damage the
three-way catalytic converter.
•
Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot
exhaust system 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 cata-
lytic converter or exhaust system over-
heating.
•
Remember that tampering or unauthor-
ized modifications to the engine, the
Engine Control Module, or the vehicle may
be illegal and can cause three-way cata-
lytic converter or exhaust system over-
heating. This includes: altering fuel injec-
tion settings or components, altering
emission system components or location
or removing components, and/or repeated
use of leaded fuel.
Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensors
The heated oxygen sensors monitor the oxy-
gen 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 combus-
tion 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 electrical 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 functions 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.
–
To charge the battery, start the engine and
let it run for at least 15 minutes (driving
charges the battery faster than letting the

cause cancer and reproductive harm. Wash
hands after handling.
WARNING
•
Batteries generate hydrogen gas,
which is flammable and explosive.
•
Do not connect the jumper cable to
any part of the fuel system or to any
moving parts. Avoid touching hot
manifolds.
•
Battery fluid contains sulfuric acid. Do
not allow battery fluid to contact eyes,
skin, fabrics or painted surfaces.
•
If contact occurs, flush the affected
area immediately with water. Obtain
medical help immediately if eyes are
affected.
•
Never expose the battery to open flame
or electric spark. Do not smoke near
the battery. Failure to follow the
instructions for jump starting can lead
to injury.
If the starter battery has been discharged
to the extent that the vehicle does not have
normal electrical functions and the engine
must then be jump-started with an external
battery or a battery charger, the Start/Stop
function may remain activated. If the Start/
Stop function shortly thereafter auto-stops
the engine, there is a huge risk that auto-
start of the engine will fail due to insuffi-
cient battery capacity since the battery had
not had time to recharge.
If the vehicle has been jump-started or if
there has not been enough time for the
battery to be charged with a battery
charger, the Start/Stop function should be
temporarily deactivated until the battery
has been recharged by the vehicle. At an
ambient temperature of about +15°C
(about 60°F), the battery must be charged
by the vehicle for at least one hour. At
lower ambient temperatures, the charging
time can increase to 3-4 hours. It is advisa-
ble to charge the battery with an external
battery charger.
