goal. In addition to continuous environmentalrefinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles.
When you drive a Volvo, you become our partnerin the work to lessen the vehicle's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
•Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
•Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
•Drive at a constant speed whenever possible.
•See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
•Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
•When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.

Twin Engine vehicles
•If possible, precondition the vehicle with thecharging cable before driving.
•If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.
•Choose the Pure drive mode to help mini-mize electric power consumption.
•In hilly terrain, put the gear selector in modeB to utilize the electric motor's braking func-tion when the accelerator pedal is released.This helps charge the hybrid battery.

IntelliSafe - driver support
IntelliSafe is Volvo Cars' philosophy regardingvehicle safety. IntelliSafe consists of a number ofsystems, both standard and optional, that aredesigned to help make driving safer, preventaccidents and protect passengers and otherroad users.
Support
IntelliSafe includes driver support functions suchas Adaptive cruise control* which helps the driverto maintain an even speed combined with a pre-selected time interval to the vehicle ahead.
Pilot Assist4 helps the driver keep the vehicle inthe current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
Park Assist Pilot* helps the driver pull into andout of parking spaces.
Other examples of systems that can help thedriver are the Active main beam, Cross TrafficAlert (CTA)* and Blind Spot Information (BLIS)*systems.

Prevention
City Safety is a function intended to help preventaccidents. The function can help prevent or miti-gate a collision with pedestrians, cyclists, largeanimals or other vehicles. Light, sound and pulsa-tions in the brake pedal are provided to alert of a
4Depending on market, this function can be either standard or optional.

CAUTION Objects such as chains, thin and glossy poles
or low obstacles may end up in the "signal
shadow" and then go temporarily undetected
by the sensors – the pulsating tone may then
unexpectedly stop instead of becoming a
constant tone as expected.
The sensors cannot detect high objects, such
as protruding ramps.
• In such situations, pay extra attention and
maneuver/drive the vehicle very slowly or
stop the current parking maneuver –
there may be a high risk of damage to
the vehicle or other objects since infor-
mation from the sensors is not always
reliable in such situations.
CAUTION In some circumstances, the Park Assist Sys-
tem may produce false warnings due to exter-
nal sound sources with the same ultrasonic
frequencies as those the system works with.
Examples of such sources are horns, wet tires
on asphalt, pneumatic brakes, exhaust noise
from motorcycles, etc.
NOTE When a trailer hitch is configured with the
vehicle electrical system, the trailer hitch pro-
trusion is included when the function meas-
ures the distance to objects behind the vehi-
cle.

Park Assist Pilot PAP 127
may not be able to
detect all conditions in all situations and func-
tionality may therefore be limited.
WARNING •
The PAP function is supplementary driver
support intended to facilitate driving and
help make it safer – it cannot handle all
situations in all traffic, weather and road
conditions.
• Pay particular attention to people and
animals near the vehicle.
• Bear in mind that the front end of the
vehicle may swing out towards oncoming
traffic during the parking maneuver.
• Objects situated higher than the detec-
tion area of the sensors are not included
when the parking maneuver is calculated,
which could cause PAP to swing into the
parking space too early. Such parking
spaces should be avoided for this reason.
• PAP is not a substitute for the driver's
attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.
The driver should be aware of the following limi-
tations for Park Assist Pilot:The parking sequence is cancelledA parking sequence will be cancelled if:
• the driver moves the steering wheel
• the vehicle's speed exceeds 7 km/h (4 mph)
• the driver taps
Cancel in the center display
• when the anti-lock brakes or the Electronic
stability control are engaged - e.g. when a
wheel loses grip on a slippery road
• when the power steering works at reduced
power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").
A message in the center display will explain why
the parking sequence was cancelled.
CAUTION Under certain circumstances, PAP may not be
able to find parking spaces – one reason may
be that the sensors are disrupted by external
sound sources that emit the same ultrasonic
frequencies that the system works with.
Examples of such sources include horns, wet
tires on asphalt, pneumatic brakes, exhaust
noise from motorcycles, etc.

NOTEDirt, ice and snow covering the sensors
reduce their function and can make measure-
ment impossible.
Driver responsibilityThe driver should keep in mind that PAP is a
parking aid ‒ not an infallible fully automatic sys-
tem. The driver must always be prepared to take
control and cancel a parking sequence if neces-
sary.
There are a number of things to keep in mind
when parking, including:
• The driver is always responsible for determin-
ing if the space suggested by PAP is suita-
ble for parking.
• Do not use PAP when using snow chains or
a temporary spare tire.
• Do not use PAP if there are any objects pro-
truding from the vehicle.
• Heavy rain or snowfall may inhibit PAP's abil-
ity to accurately measure a parking space.
• While searching and measuring the parking
space, PAP may be unable to detect objects
located far into the space.
• PAP may not suggest parking spaces on
narrow streets if it does not detect sufficient
space for maneuvering the vehicle. •
Use approved tires 128
inflated to the correct
tire pressure because this affects PAP's abil-
ity to provide parking assistance.
• PAP's function is based on the way the vehi-
cles are parked behind and in front of your
parking space. If they are, for example,
parked too close to the curb, there is a risk
that your vehicle's tires or wheel rims could
be damaged by the curb during the parking
procedure.
• Perpendicular parking spaces may not be
detected or may be suggested unnecessarily
if a parked vehicle is sticking out more than
other parked vehicles.
• PAP is intended to provide parking assis-
tance on straight streets, not sections of
street with sharp curves or bends. Always
make sure that your vehicle is parallel to rel-
evant parking spaces when PAP is measur-
ing the parking space.
CAUTION Switching to another approved wheel and/or
tire dimension could change the tire circum-
ference, which would then require the PAP
system to be updated. Consult a workshop –
an authorized Volvo workshop is recom-
mended.

450 Leveling control* and suspension
The vehicle's leveling control system adjusts the
suspension and shock absorbers automatically
to help provide good comfort and control while
driving. Leveling can also be controlled manually
to facilitate loading or getting in and out of the
vehicle.
Pneumatic suspension and shock
absorbers
The system is adapted to the selected drive
mode and vehicle speed. The pneumatic suspen-
sion reduces the vehicle's ground clearance at
higher speeds to reduce air resistance and
increase stability. The shock absorbers are nor-
mally set to provide the best possible comfort and are adjusted continuously according to the
road surface and the vehicle's acceleration, brak-
ing and cornering.
The instrument panel indicates
when the suspension level is
being adjusted. The level cannot be adjusted when any of the
side doors or the tailgate is open.
ParkingWhen parking, make sure that there is adequate
space above and below the vehicle since ground
clearance may vary depending on e.g. ambient
temperature, how the vehicle is loaded, if loading
mode is used, which drive mode is selected after
the engine is started, etc.
The level may also be adjusted a period after the
vehicle is parked. This is to compensate for any
height changes that may occur due to tempera-
ture changes in the air springs when the vehicle
cools.
TransportingWhen transporting the vehicle on a ferry, train or
truck, only secure (lash) the vehicle around the
tires, not using any other parts of the chassis.
Changes in the pneumatic suspension may occur
during transport, which could adversely affect the
lashing and result in damage.

Driving
• Choose the Pure drive mode to help mini-
mize electric power consumption.
• Maintain a steady speed and a generous fol-
lowing distance to traffic ahead to minimize
braking. This drive mode has the lowest
power consumption.
• Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel to see available electric
power and avoid starting the combustion
engine unnecessarily. The electric motor is
more effective than the combustion engine,
especially at low speeds.
• When braking is necessary, brake gently
using the brake pedal. This will recharge the
hybrid battery. A regenerative function is
integrated in the brake pedal and can be
augmented by the electric motor's braking
capacity when the gear selector is in mode
B.
• Higher speeds increase energy consumption
- air resistance increases with speed.
• Activate the
Hold function in the Function
view 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 battery. Charg-
ing the battery using the combustion engine increases fuel consumption and carbon diox-
ide emissions.
• In a cold climate, reduce heating of the wind-
shield/rear window, mirrors, seats and the
steering wheel.
• Maintain the correct pressure in the tires and
check pressure regularly.
• The type of tires used could affect energy
consumption - consult a retailer for advice on
suitable tires.
• Remove unnecessary items from the vehicle
- the heavier the load, the higher the fuel
consumption.
• Roof loads increase air resistance and
increase fuel consumption. Remove roof
boxes, ski racks, etc. that are not in use.
• Avoid driving with the windows open.
• Do not keep the vehicle still on an upward
gradient by using the accelerator pedal. Use
the brakes instead.

When using the electric motor, Volvo Twin
Engine provides a combination of good fuel
economy, low emissions and high performance.
For energy-efficient driving:
• Select the Pure drive mode to help maximize
driving range using only the electric motor.
• Balance energy requirements using the
accelerator pedal. Use the indicator on the
instrument panel's hybrid gauge to see avail-
able electric power and avoid starting the
combustion engine unnecessarily.
• When braking is necessary, brake gently
using the brake pedal. This will recharge the
hybrid battery.
• Activate the
Hold function in the Function
view at high speeds when traveling farther
than is possible using the hybrid battery's
capacity.
• Reduce current consumption in the passen-
ger compartment by reducing e.g. fan speed,
electric heating, or air conditioning use.
Also follow the general economical driving advice
regarding speed, tires and load to maximize
range.

Factors the driver can control
The driver should be aware that the following fac-
tors help conserve energy and improve driving
range: • charging the battery regularly
• preconditioning
• Pure drive mode
• climate control settings
• speed and acceleration
• the
Hold function
• tires and tire pressure.
The following table shows the approximate rela-
tionship between constant speed and driving
range. Driving at a lower constant speed helps
increase the electric motor's driving range. Constant speed

The figures shown in the tables pertain to
a new vehicle.
• None of the figures are absolute and are
affected by e.g. driving style, environment
and other conditions.

In certain situations, it can be useful to control
the hybrid battery's charge level while driving.
This is possible with the Hold and Charge func-
tions, which are available in all drive modes.
Function buttons for Hold and ChargeThe functions can be activated in the center dis-
play'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 availa-
ble electrical current for use at
a later time, such as when driving in an urban
area or residential neighborhood. Hold is availa-
ble regardless of the hybrid battery's charge level.
The vehicle will function as in normal hybrid driv-
ing with a discharged battery - in addition to
reusing energy from e.g. regenerative braking, the
combustion engine will be used more frequently
to maintain the charge in the battery.
