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

possible collision and help the driver act in timeto prevent it. If the driver does not react to thewarning and the risk of collision is determined tobe imminent, City Safety can automatically applythe brakes.
Lane assistance (LKA) is another example of afunction that can help prevent accidents by help-ing the driver - on expressways and similar largerroads - to reduce the risk of the car accidentallyleaving its own lane.
The function Steering aid during increasedcollision risk can help the driver reduce the riskof the car leaving its lane unintentionally and/orcolliding with another vehicle or obstacle byactively steering the car back into its lane and/orswerving.

Protection
To help protect the driver and passengers, thevehicle is equipped with seat belt tensioners thatpull the seat belts taut in collisions and other crit-ical situations. The vehicle also has airbags, inflat-able curtains and the Whiplash ProtectionSystem (WHIPS), which helps prevent whiplashinjuries.

Speed-dependent steering wheelresistance
Speed-dependent power steering increases thesteering wheel resistance in pace with the vehi-cle's speed to give the driver an enhanced feel-ing of control and stability.
Steering may feel stiffer on highways. Whenparking and at low speeds, it will be easier tomove the steering wheel.
NOTE
In some situations, the power steering maybecome too hot and require temporary cool-ing – during such time the power steering willwork at reduced output and the steeringwheel may feel more difficult to move.
In parallel with the temporarily reduced steer-ing assistance, the driver display shows amessage as well as a STEERING WHEELsymbol.

WARNING
While the power steering is working atreduced power, the driver support functionsand systems with steering assistance are notavailable.
In such a situation, the driver display showsthe Power steering failure message, com-bined with a STEERING WHEEL symbol.

Electronic Stability Control
The Electronic Stability Control (ESC1) functionhelps the driver avoid skidding and improves thevehicle's directional stability.
This symbol will be displayed inthe instrument panel when theESC system is intervening.
When the ESC has intervenedto apply the brakes, a pulsingsound may be heard and thevehicle may accelerate more slowly than expec-ted when the accelerator pedal is depressed.
The ESC system consists of the following sub-functions:
Stability control2
Spin control and active yaw control
Engine drag control
WARNING
The Electronic Stability Control systemESC is supplementary driver supportintended to facilitate driving and make itsafer – it cannot handle all situations inall traffic, weather and road conditions.
ESC is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Stability control 2
This function helps control the driving and brak-ing force of each individual wheel in an attemptto stabilize the vehicle.

Spin control and active yaw control
This function is active at low speeds and brakesthe wheels that are spinning to transfer additionalpower from wheels that are not spinning.
This function also helps prevent the wheels fromspinning while the vehicle is accelerating.
1Electronic Stability Control2Also called traction control.

DRIVER SUPPORT

Passing assistance with AdaptiveCruise Control
Adaptive Cruise Control (ACC43) can assist thedriver when passing other vehicles.
How passing assistance works
When ACC is following another vehicle and youindicate that you intend to pass that vehicle by
using the turn signal44, Adaptive Cruise Controlwill begin accelerating toward the vehicle aheadbefore your vehicle has moved into the passinglane.
The function will then delay a speed reduction toavoid early braking as your vehicle approaches aslower-moving vehicle.
The function remains active until your vehicle haspassed the other vehicle.

WARNING
Please note that this function can be acti-vated in more situations than just passinganother vehicle, such as when a direction indi-cator is used to indicate a lane change orbefore exiting to another road – the vehiclewill then briefly accelerate.

Starting passing assistance withAdaptive Cruise Control
Several conditions must be met for passingassistance to be possible.

Requirements for passing assistance
In order to activate passing assistance:
your vehicle must be following a vehicleahead (target vehicle)
your vehicle's current speed must beat least 70 km/h (43 mph)
the set speed for ACC must be highenough to safely pass another vehicle.

Starting parking assistance
To start passing assistance:
–Turn on the left turn signal.
> Passing assistance will start.

Limitations of passing assistancewith Adaptive Cruise Control
Passing assistance functionality may be reducedin certain situations.
WARNING
The driver should be aware that if conditionssuddenly change when using Parking Assis-tance, the function may implement an unde-sired acceleration in certain conditions.
Some situations should be avoided, e.g. if:
the vehicle is approaching an exit in thesame direction as passing would normallyoccur
the vehicle ahead slows before your vehi-cle has had time to switch to the passinglane
traffic in the passing lane slows down
a vehicle for right-hand traffic is driven ina country with left-hand traffic (or viceversa).
Situations of this type can be avoided by tempo-
rarily putting ACC45 in standby mode.

Switching target vehicles withAdaptive Cruise Control
At certain speeds, models with automatic trans-
missions and Adaptive Cruise Control (ACC46)can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may bestationary traffic ahead.
When Adaptive Cruise Control is actively follow-ing another vehicle at speeds under 30 km/h(20 mph) and switches targets from a movingvehicle to a stationary vehicle, Adaptive CruiseControl will brake for the stationary vehicle.
