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 Assist2 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
2Depending on market, this function can be either standard or optional.

Park Assist limitations
Park Assist may not be able to detect all condi-tions in all situations and functionality may there-fore be limited in certain cases.
The driver should be aware of the following limi-tations for Park Assist:

WARNING
Be extra cautious whenreversing if this symbol isshown when a trailer, bikecarrier or similar is attachedand electrically connectedto the vehicle.
The symbol indicates thatthe rear parking assist sensors are deacti-vated and will not warn of any obstacles.
CAUTION
Objects such as chains, thin and glossy polesor low obstacles may end up in the "signalshadow" and then go temporarily undetectedby the sensors – the pulsating tone may thenunexpectedly stop instead of becoming aconstant tone as expected.
The sensors cannot detect high objects, suchas protruding ramps.
In such situations, pay extra attention andmaneuver/drive the vehicle very slowly orstop the current parking maneuver –there may be a high risk of damage tothe vehicle or other objects since infor-mation from the sensors is not alwaysreliable 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 ultrasonicfrequencies as those the system works with.
Examples of such sources are horns, wet tireson asphalt, pneumatic brakes, exhaust noisefrom motorcycles, etc.
NOTE
When a trailer hitch is configured with thevehicle electrical system, the trailer hitch pro-trusion is included when the function meas-ures the distance to objects behind the vehi-cle.

The parking sequence is cancelled
A 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 Electronicstability control are engaged - e.g. when awheel loses grip on a slippery road
when the power steering works at reducedpower - e.g. during cooling due to overheat-ing (see section "Speed-dependent steeringforce").
A message in the center display will explain whythe parking sequence was cancelled.

CAUTION
Under certain circumstances, PAP may not beable to find parking spaces – one reason maybe that the sensors are disrupted by externalsound sources that emit the same ultrasonicfrequencies that the system works with.
Examples of such sources include horns, wettires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.
NOTE
Dirt, ice and snow covering the sensorsreduce their function and can make measure-ment impossible.

Driver responsibility
The driver should keep in mind that PAP is aparking aid ‒ not an infallible fully automatic sys-tem. The driver must always be prepared to takecontrol and cancel a parking sequence if neces-sary.
There are a number of things to keep in mindwhen 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 ora 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 parkingspace, PAP may be unable to detect objectslocated far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect sufficientspace for maneuvering the vehicle.
Use approved tires121 inflated to the correcttire 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 yourparking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims couldbe damaged by the curb during the parkingprocedure.
Perpendicular parking spaces may not bedetected or may be suggested unnecessarilyif a parked vehicle is sticking out more thanother parked vehicles.
PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with sharp curves or bends. Alwaysmake 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/ortire dimension could change the tire circum-ference, which would then require the PAPsystem to be updated. Consult a workshop –an authorized Volvo workshop is recom-mended.
121"Approved tires" refers to tires of the same type and make as the vehicle's original, factory-installed tires.

Leveling control* and suspension
Self-leveling and suspension functions are con-trolled automatically.
Rear leveling control keeps the rear section ofthe vehicle at the same height regardless of load.Leveling control may also remain active when thevehicle is parked.

Shock absorbers (Four-C)
The shock absorbers are adapted to the selecteddrive mode and vehicle speed. The shock absorb-ers are normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface and the vehicle's acceleration,braking and cornering.
Transporting
When transporting the vehicle on a ferry, train ortruck, only secure (lash) the vehicle around thetires, not using any other parts of the chassis.Changes in the pneumatic suspension may occurduring transport, which could adversely affect thelashing 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 minimizebraking. This drive mode has the lowestpower consumption.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel to see available electricpower and avoid starting the combustionengine unnecessarily. The electric motor ismore effective than the combustion engine,especially at low speeds.
When braking is necessary, brake gentlyusing the brake pedal. This will help rechargethe hybrid battery. A regenerative function isintegrated in the brake pedal and can beaugmented by the electric motor's brakingcapacity when the gear selector is in modeB.
Higher speeds increase energy consumption- air resistance increases with speed.
Activate the Hold function in the Functionview at high speeds when traveling fartherthan is possible using the hybrid battery'scapacity.
Whenever possible, avoid using the Chargefunction 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 thesteering wheel.
Maintain the correct pressure in the tires andcheck pressure regularly.
The type of tires used could affect energyconsumption - consult a retailer for advice onsuitable tires.
Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upwardgradient by using the accelerator pedal. Usethe brakes instead.

Using the electric motor only
When using the electric motor, Volvo TwinEngine provides a combination of good fueleconomy, low emissions and high performance.
For energy-efficient driving:
Select the Pure drive mode to help maximizedriving range using only the electric motor.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel's hybrid gauge to see avail-able electric power and avoid starting thecombustion engine unnecessarily.
When braking is necessary, brake gentlyusing the brake pedal. This will recharge thehybrid battery.
Activate the Hold function in the Functionview at high speeds when traveling fartherthan is possible using the hybrid battery'scapacity.
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 adviceregarding speed, tires and load to maximizerange.

"Hold" and "Charge" functions
In certain situations, it can be useful to controlthe hybrid battery's charge level while driving.This is possible with the Hold and Charge func-tions.
Hold and Charge are available in all drivemodes. The functions will switch off if Pure drivemode is activated.

Function buttons for Hold and Charge
The functions can be activated in the center dis-play's Function view.

Hold
Battery level sustained forlater use.
This function retains the chargein the hybrid battery for theelectric motor and saves availa-ble electrical current for use ata later time, such as when driving in an urbanarea or residential neighborhood.
The vehicle will function as in normal hybrid driv-ing with a discharged battery - in addition toreusing energy from e.g. regenerative braking, thecombustion engine will be used more frequentlyto maintain the charge in the battery.
