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

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.

CAUTION
Parts of the vehicle (e.g. engine, transmission,driveline, electrical components, etc.) can bedamaged if the vehicle is driven through waterhigher than its floor level. Damage to anycomponents caused by flooding, vapor lock orinsufficient oil is not covered under warranty.
If the engine stalls while the vehicle is inwater, do not attempt to restart it. Have thevehicle towed on the bed of a tow truck to aworkshop - an authorized Volvo workshop isrecommended.

CAUTION
Because it can be difficult to determine thewater depth, avoid driving through standing orrunning water.
When you have passed the water, press lightly onthe brake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc. canmake the brake linings slippery, resulting indelayed braking effect.
If the vehicle is equipped with a trailer couplingcontact, clean the contact after driving in water ormud.

Tires
The function of the tires is to carry loads, providetraction on road surfaces, reduce vibrations andprotect the wheels from wear.
The tires significantly influence the vehicle's driv-ing characteristics. The type, dimensions, tirepressure and speed rating have a considerableimpact on how the vehicle performs.
Your vehicle is equipped with tires according tothe vehicle's tire information placard on the B-pil-lar (the structural member at the side of the vehi-cle, at the rear of the driver's door opening).

WARNING
A damaged tire could cause the driver to losecontrol of the vehicle.
CAUTION
Some Volvo models are equipped with anUltra High Performance tire and wheel com-bination designed to provide maximum drypavement performance with consideration forhydroplaning resistance. They may be moresusceptible to road hazard damage and,depending on driving conditions, may achievea tread life of less than 30,000 km (20,000miles). Even if this vehicle is equipped withVolvo's advanced AWD or stability system,these tires are not designed for winter driving,and should be replaced with winter tires whenweather conditions dictate.
The tires have good road holding characteristicsand offer good handling on dry and wet surfaces.It should be noted however that the tires havebeen developed to give these features on snow/ice-free surfaces.
Most models are equipped with "all-season" tires,which provide a somewhat higher degree of road-holding on slippery road surfaces than tires with-out the "all-season" rating. However, for optimalroadholding on icy or snow-covered roads, Volvorecommends snow tires on all four wheels.
When replacing tires, be sure that the new tiresare the same size designation, type (radial) andpreferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of alteringthe vehicle's roadholding and handling characte-ristics.

Recommended tires
On delivery, the car is equipped with Volvo origi-
nal tires that have the VOL1 marking on the sideof the tires. These tires have been designed spe-cifically for your vehicle. It is therefore importantwhen replacing tires that the new tires have thissame marking to help maintain the vehicle's driv-ing characteristics, comfort and fuel consumption.

New tires
Tires are perishable goods. After a few years,they will begin to harden and their friction proper-ties will gradually deteriorate. Always replace tireswith the freshest tires possible. This is particularlyimportant for snow tires. A series of numbers is

Checking tire pressure
Correct inflation pressure helps improve drivingstability, save fuel and increase the service life ofthe tires.
Tire pressure decreases over time, which is nor-mal. Tire pressure also varies depending on theambient temperature. Driving on under-inflatedtires could cause the vehicle to overheat and leadto damage. Tire pressure affects traveling com-fort, road noise and driving characteristics.
Check the pressure in the tires every month. Usethe recommended inflation pressure for cold tiresfor optimal tire performance and wear. Under-inflated or over-inflated tires could cause uneventread wear.
Use an air pressure gauge and check the infla-tion pressure on all the tires, including the spare
tire4, at least once a month and before long trips.Volvo strongly recommends buying a reliable airpressure gauge, as the automatic gauges provi-ded at service stations may be inaccurate.

WARNING
Under-inflation is the most commoncause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
Under-inflated tires reduce the load car-rying capacity of your vehicle.

Cold tires
Inflation pressure should be checked when thetires are cold.
The tires are considered to be cold when theyhave the same temperature as the surrounding(ambient) air.
This temperature is normally reached after thevehicle has been parked for at least 3 hours.
After driving for approximately 1.6 km (1 mile),the tires are considered to be warm. If you needto drive longer than that to inflate the tires, checkand record the inflation pressure of the tires firstand inflate accordingly when you arrive at thepump.
When the ambient temperature changes, so doesthe inflation pressure. A 10-degree temperaturedrop causes a corresponding drop in inflationpressure of 1 psi (7 kPa). Check the inflationpressure of the tires regularly and adjust to the
correct pressure, which can be found on the vehi-cle's tire information placard or certification label.
If you check inflation pressure when the tires arewarm, you should never release air. The tiresbecome warm after driving and it is normal forwarm tires to have an inflation pressure abovethe recommended pressure for cold tires. A warmtire with an inflation pressure equal to or underthe recommended pressure for cold tires couldbe significantly under-inflated.

Recommended tire pressure
The tire pressure placard on the driver's side Bpillar (between the front and the rear door) indi-cates tire pressure for different loads and speedconditions.
The decal specifies the designation for the fac-tory-mounted tires on the vehicle, as well as loadlimits and inflation pressures.

Tire pressure monitoring system*
The tire pressure monitoring system6 provides awarning symbol in the instrument panel if pres-sure is too low in one or more tires.
Symbol Explanation
This symbol illuminates to indicatelow inflation pressure.
If there is a system malfunction, theinflation pressure warning symbolwill flash for approximately oneminute and then glow steadily.
System description
The tire pressure monitoring system measuresdifferences in rotational speed between thewheels through the ABS system to determine ifthe tires are properly inflated. If inflation pressurein a tire is too low, its diameter (and consequentlyits rotational speed) changes. By comparing thetires with each other, the system can determine ifthe pressure in one or more tires is too low.

General information about the tire pressure
monitoring system
In the following description, the tire monitoringsystem is generally referred to as TPMS.
Each tire, including the spare (if provided)7
should be checked monthly when cold and infla-
ted to the inflation pressure recommended by thevehicle manufacturer on the vehicle placard ortire inflation pressure label. (If your vehicle hastires of a different size than the size indicated onthe vehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires.)
As an added safety feature, your vehicle hasbeen equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure.
Driving on a significantly under-inflated tire cau-ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tire
