Hill Descent Control
The function for assisting when driving down-
hill (HDC
12
) is a low-speed function with
increased engine braking. The function
makes it possible to increase or decrease the
vehicle's speed on steep downhill gradients
by only using the accelerator pedal, without
applying the brakes.
The function is included in the
Off Road
drive
mode.
HDC is designed for driving on rough roads at
low speeds and downhill gradients with slip-
pery or otherwise difficult road surfaces. The
driver does not need to use the brake pedal
but can instead focus on steering.
WARNING
HDC is only intended to be a supplemen-
tary braking aid and it does not function in
all situations.
The driver is always ultimately responsible
for operating the vehicle in a safe manner.
Function
Hill Descent Control allows the vehicle to
move forward or backward at very low speeds
assisted by the brake system. The driver can
increase the speed by pressing the accelerator
pedal. When the accelerator pedal is released,
the vehicle will return to very low speed
regardless of how steep the hill is and without
the brakes needing to be applied. The brake
lights will illuminate when the function is acti-
vated.
The driver can brake to stop or slow the vehi-
cle at any time by depressing the brake pedal.
HDC is activated along with Low Speed Con-
trol (LSC
13
), which facilitates and improves
traction and control on rough and slippery sur-
faces. The system is intended to be used at
low speeds, up to approximately 40 km/h (25
mph).
To keep in mind when using HDC
•
If the function is switched off while driving
on a steep downhill gradient, braking
effect will be gradually reduced.
•
HDC can be used in gear positions
D
and
R
, and in manual gears 1 or 2.
•
It is not possible to manually shift to third
gear or higher when HDC is active.
When LSC with HDC is activated in the
Off Road
drive mode, the feel of the accel-
erator pedal and engine response will
change.
This drive mode is not designed to be used
for normal street driving.
The function is deactivated when driving at
high speeds and must be reactivated at
lower speeds if so desired.

Economical driving
To achieve the longest possible driving range,
the driver should plan the trip and adapt driv-
ing style and speed to the current situation.
Before driving
•
Whenever possible, precondition the vehi-
cle before driving by connecting the
charging cable to an electrical outlet.
•
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 hybrid battery.
•
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
Pure
drive mode.
•
Activate the
Hold
function at high speeds
when traveling farther than is possible
using the hybrid battery's capacity.
•
Whenever possible, avoid using the
Charge
function to charge the hybrid bat-
tery.

•
Maintain a steady speed and a generous
following distance to traffic ahead to mini-
mize braking.
•
When braking, the hybrid battery is
charged by braking lightly using the brake
pedal.
•
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.
•
If possible, turn off the climate system
when driving shorter distances after pre-
conditioning.
After driving
•
If possible, park in a climate-controlled
garage with vehicle charging outlets or
stations.

Range
A number of factors can affect vehicle range.
The ability to achieve a long driving range var-
ies according to the outside conditions and to
how the vehicle is driven.
The certified value for the vehicle's range
should not be considered an expected driving
range. The certified value is obtained during
special test cycles and is primarily intended to
be used for comparisons between different
vehicles.
Range in the instrument panel
When the vehicle leaves the factory, or after a
factory reset, range is based on the certified
value
Once the vehicle has been driven for a while,
range is instead based on historical driving
patterns. The amount of history used depends
on the battery's charge level. The lower the
-------------------------------------------------------------------------------------------------------------------------------------------------------------
STARTING AND DRIVING
461
charge level of the hybrid battery, the more
quickly the range adapts to changed driving
patterns.
Factors affecting driving range
There are a number of other factors in addition
to historical trip data that affect range. The
longest range is achieved under very favorable
conditions when all factors positively influence
range.
Factors affecting range include:
•
speed
•
climate control settings
•
topography
•
preconditioning
•
tires and tire pressure
•
the current traffic situation
•
temperature and weather
•
road conditions.

-10 °C (14 °F) ambient temperature and
passenger compartment climate control
on.
The graph shows the approximate relationship
between constant speed and driving range.
Driving at a lower constant speed helps
increase the electric motor's driving range.
Higher ambient temperature and deactivated
climate system are also more favorable for
range.

Hold and Charge
In certain situations, it can be useful to con-
trol the hybrid battery's charge level while
driving. This is possible with the
Hold
and
Charge
functions.
Hold
and
Charge
are available in all drive
modes. The functions will switch off if
Pure
drive mode is activated.
Activating Hold and Charge
The functions can be activated in the center
display's Function view.
Hold
Battery level sustained for
later use
.
This function retains the
charge in the hybrid battery
for the electric motor and
saves available electrical cur-
rent for use at a later time, such as when driv-
ing in an urban area.
The vehicle will function as in normal hybrid
driving with a discharged battery - in addition
to reusing energy from e.g. regenerative brak-
ing, the combustion engine will be used more
frequently to maintain the charge in the bat-
tery.
Charge
Engine charges hybrid
battery
.
This function charges the
hybrid battery with the help
of the combustion engine for
increased use of the electric
motor at a later time.

Preparing for a long trip
It is important to have the vehicle's systems
and equipment checked carefully before driv-
ing long distances.
Check that
•
the engine is running properly and that
fuel consumption is normal
•
there are no leaks (fuel, oil or other fluid)
•
the brake pedal is functioning properly
•
all lights work
•
tire tread depth and air pressure are at
correct levels. Change to snow tires when
driving in areas where there is a risk of
snowy or icy roads
•
the start battery is sufficiently charged
•
the wiper blades are in good condition

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.
To help prevent damage to the vehicle when
driving through water:
•
Do not drive in water higher than the floor
of the vehicle. If possible, check the depth
of the water at its deepest point before
driving through it. Be particularly careful
when driving through flowing water.
•
Always select the
Off Road
drive mode
before driving in water to ensure the gaso-
line engine is running.
•
Do not drive faster than walking speed.
•
Do not stop the vehicle in the water. Drive
carefully forward or back the vehicle out of
the water.
•
Remember that waves created by passing
vehicles could cause the water level to rise
above the vehicle's floor level.
•
Avoid driving through salt water to help
avoid the risk of corrosion.
Parts of the vehicle (e.g. engine, transmis-
sion, driveline, electrical components, etc.)
can be damaged if the vehicle is driven
through water higher than its floor level.
Damage to any 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 on the bed of a tow
truck to a workshop - an authorized Volvo
workshop is recommended.
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.
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 a trailer cou-
pling contact, clean the contact after driving in
water or mud.

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
-------------------------------------------------------------------------------------------------------------------------------------------------------------

468
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
14
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
engine idle).
