Fuel requirements

140
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 meet sea-
sonal air quality standards, some areas require
the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygen-
ated" fuels; however, the octane ratings listed
on page 139 must still be met.
Alcohol – EthanolFuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred to
as Ethyl alcohol, or "Gasohol".
Ethers – MTBE: Fuels containing up to
15% MTBE may be used.
MethanolDo 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.
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 recommended
pressure 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 145). Many electrical systems (the
audio system, the optional infotainment/
navigation systems, power windows, etc)
will function with the ignition key in positionI. 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. Driving or having the engine run-
ning for approximately 15 minutes will help
keep the battery charged.
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
Stability system
06
157 Dynamic Stability Traction Control
(DSTC)
The stability system consists of a number of
functions designed help reduce wheel spin,
counteract skidding, and to generally help
improve directional stability.
NOTE
A pulsating sound will be audible when the
system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel
spin by transferring power from a drive wheel
that begins to lose traction to the wheel on the
opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of DSTC's permanent functions and
cannot be switched off.
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
Temporarily switching off Spin control1. Turn the thumbwheel (1) on the left-side
steering wheel lever until the DSTC menu
is displayed.
2.
Hold down the RESET button (2) to toggle
between
DSTC ON or DSTC SPIN
CONTROL OFF.
NOTE
•The message DSTC SPIN CONTROL
OFF indicates that the stability sys-
tem's spin control function has tempo-
rarily been switched off.
•The stability control indicator light will
illuminate and remain on until spin con-
trol has been reactivated.
•The spin control function is automati-
cally enabled each time the engine is
started.
•DSTC ON indicates that all system
functions are active.
Active Yaw Control (AYC)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.
This is one of DSTC's permanent functions and
cannot be switched off.
WARNING
The car's handling and stability characteris-
tics will be altered if the DSTC system func-
tions have been disabled.

Towing
06
162
CAUTION
Vehicles with AWD (All Wheel Drive) with the
front wheels off the ground should not be
towed at speeds above 50 mph (70 km/h) or
for distances longer than 30 miles (50 km).
CAUTION
•Please check with state and local
authorities before attempting this type
of towing, as vehicles being towed are
subject to regulations regarding maxi-
mum towing speed, length and type of
towing device, lighting, etc.
•If the vehicle'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 151).
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to pull the vehicle up onto the flat
bed or to secure the vehicle on the flat
bed. Consult the tow truck operator.
WARNING
•The power brakes and power steering
will not function when the engine is not
running. Approximately 5 times more
pressure will be required on the brake
pedal and the steering wheel will be
considerably harder to turn.
•The towing eyelets must not be used for
pulling the vehicle out of a ditch or for
any similar purpose involving severe
strain. Do not use the towing eyelets to
pull the vehicle up onto a flat bed tow
truck.
G030862
Towing vehicles with front wheel drive/
All Wheel Drive
Volvo recommends the use of flat bed equip-
ment.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle. In this case, the vehicle should
be towed with the rear wheels on the ground
if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.
CAUTION
•Sling-type equipment applied at the
front will damage radiator and air con-
ditioning lines.
•It is equally important not to use sling-
type equipment at the rear or apply lift-
ing equipment inside the rear wheels;
serious damage to the rear axle may
result.
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to secure the vehicle on the flat
bed. Consult the tow truck operator.

Belt check
Check the belt regularly to make sure it is in
good condition and is clean. A worn or dirty belt
can cause poor cooling and low alternator out-
put as well as impair the operation of the power
steering and the air conditioning unit.
NOTE
The drive belt is equipped with a self-ten-
sioning mechanism and requires no adjust-
ment between changes.
WARNING
The engine must not be running when this
check is performed.
Check coolant level
The cooling system must be filled with coolant
and not leak to operate at maximum efficiency.
Check the coolant level regularly. The level
should be between the MAX and MIN marks
on the expansion tank. The check should be
made with particular thoroughness when the
engine is new or when the cooling system has
been drained.
Do not remove the filler cap other than for top-
ping up with coolant. Frequent removal may
prevent coolant circulation between the engineand the expansion tank during engine warm up
and cooling.
Changing coolant
Normally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
Do not top off with water only. This reduces the
rust-protective and antifreeze qualities of the
coolant and has a lower boiling point. It can
also cause damage to the cooling system if it
should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water
and antifreeze.
CAUTION
The cooling system must always be kept
filled to the correct level. If it is not kept filled,
there can be high local temperatures in the
engine which could result in damage. Dif-
ferent types of antifreeze/coolant may not
be mixed.
WARNING
•Never remove the expansion tank cap
while the engine is warm. Wait until the
engine cools.
•If it is necessary to top off the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
