IntelliSafe - driver support
IntelliSafe is Volvo Cars' philosophy regarding vehicle 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.
SupportIntelliSafe includes driver support functions such as Adaptive cruise control * which helps the driver
to maintain an even speed combined with a pre- selected time interval to the vehicle ahead. Pilot Assist 4
helps the driver keep the vehicle in
the current traffic lane by providing steering assistance and maintaining an even speed and aset time interval to the vehicle ahead. Park Assist Pilot * helps the driver pull into and
out of parking spaces. Other examples of systems that can help the driver are the Active main beam, Cross Traffic Alert (CTA) * and Blind Spot Information (BLIS) *
systems.
PreventionCity Safety is a function intended to help prevent accidents. 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

Start/Stop function
Start/Stop is a function that temporarily switches off the engine when the vehicle has stopped,e.g. at a traffic light or in heavy traffic, and thenstarts it again automatically when the brakepedal is released.
The Start/Stop function reduces fuel consump- tion, which helps to reduce exhaust emissions. The system makes it possible to drive more eco- nomically and climate-smart by letting the engineauto-stop when appropriate.

Driving with the Start/Stop function
Start/Stop is a function that temporarily turns off the engine when the vehicle is stationary andthen automatically starts it again when the vehi-cle starts moving.
The Start/Stop function is available when the engine is started and can be activated if certainconditions are met. The instrument panel indi-cates if the function is available, active or notavailable. All of the vehicle's ordinary systems, such as lighting, radio, etc. function normally when theengine has been auto-stopped. Certain functionsmay be temporarily reduced, however, such asthe climate system's blower speed or extremelyhigh audio system volume.
Auto-stopTo auto-stop the engine:
• Stop the vehicle by applying the brakes andkeep the brake pedal depressed. The enginewill auto-stop.
In Eco or Comfort 6
drive mode, the engine may
auto-stop before the vehicle has completely stop-ped. With Adaptive Cruise Control or Pilot Assist acti- vated, the engine will auto-stop after approxi-mately three seconds.
Auto-startThe following conditions must be met for theengine to auto-start. • Release the brake pedal. The engine will auto-start and the vehicle can be driven. Onan uphill gradient, Hill Start Assist (HSA) willactivate to help prevent the vehicle from roll-ing backward.
• When Auto-hold is activated, auto-start willbe delayed until the accelerator is pressed.
• When Adaptive Cruise Control or Pilot Assistare activated, the engine will auto-start whenthe accelerator pedal is depressed or the
button on the left-side steering wheel
keypad is pressed.
• Maintain pressure on the brake pedal and press the accelerator pedal. The engine willauto-start.
• On a downhill gradient: Release the brakepedal slightly so that the vehicle begins toroll. The engine will auto-start after a slightincrease in speed.

Economical driving
Drive economically and environmentally con- scious by thinking ahead, avoiding rapid startsand stops and adapting driving style and speedto the current traffic conditions.
Driving economically conserves natural resources
Observe the following rules:
• Do not warm up the engine by idling. It is better to begin driving normally immediately after starting the engine. A cold engine uses more fuel than a warm engine and is subject to increased wear.
• Whenever possible, avoid using the vehicle todrive short distances. The engine does nothave time to reach a normal operating tem-perature and this leads to increased fuelconsumption.
• Maintain a steady speed and a generous fol-lowing distance to traffic ahead to minimizebraking.
• For lower fuel consumption, activate Ecodrive mode.
• Use the Eco Coast function in drive mode Eco - engine braking is deactivated, allowing the vehicle's kinetic energy to be used to rollgreater distances.
• Use gear
D as often as possible and avoid
using the kick-down function. •
Fuel consumption is increased at highspeeds - air resistance increases with speed.
• Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
• Maintain the correct pressure in the tires andcheck pressure regularly.
• The type of tires used could affect fuel con-sumption - consult a retailer for advice onsuitable tires.
• Do not use winter tires after the winter sea-son has ended.
• Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
• Avoid driving with the windows open.
• Using the trip computer's fuel consumptionindicators can help you learn how to drivemore economically.
Other factors that decrease fuel
consumption
• Dirty air cleaner.
• Dirty engine oil and clogged oil filter.
• Incorrect front-end alignment.
• Incorrect wheel alignment.
Some of the above items and others are checked as part of Volvo's standard maintenance sched-ule.

Driving with a trailer
There are a number of things to consider when towing a trailer, such as the towbar, the trailerand how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehi- cle's curb weight. The total weight of all passen-gers and any installed accessories, e.g. towbar,reduces the vehicle's load-carrying capacity bythe corresponding amount. • Towbars used on the vehicle must be approved for the applicable use.
• Distribute the load on the trailer so that theweight on the towbar complies with thespecified maximum towball weight. Thetongue weight is calculated as part of thevehicle's payload.
• Increase the tire pressure to the recom-mended pressure for a full load.
• The engine is subjected to more load thanusual when towing a trailer.
• Towing a trailer affects the vehicle's han-dling, durability and driving economy.
• Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
• On long and steep downgrades, the vehicle'sbrakes are subjected to much more loadthan usual. When manually shifting, down-shift and adapt speed accordingly. •
Follow applicable regulations regarding per-mitted speed and weight.
• Drive slowly when towing a trailer up a longand steep incline.
• The maximum trailer weights given only applyto altitudes up to 1000 meters (3280 feet)above sea level. At higher altitudes, enginepower (and thus the vehicle's climbing ability)is decreased due to the reduced air density,and the maximum trailer weight must there-fore be reduced. The weight of the vehicleand trailer must be decreased by 10% foreach additional 1000 m (3280 feet) or partthereof.
• Avoid driving with a trailer on inclines of morethan 12%.
• Avoid overloading and other incorrect use.
• The trailer's brakes must be balanced withthe vehicle's brakes to help ensure safestops (follow applicable local regulations).

WHEELS AND TIRES

Tires
The function of the tires is to carry loads, provide traction 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 to the 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 lose control of the vehicle.
CAUTION
Some Volvo models are equipped with an Ultra 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 characteristics and 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, werecommend snow tires on all four wheels. When replacing tires, be sure that the new tires are 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 tiresOn delivery, the car is equipped with Volvo origi- nal tires that have the VOL
1
marking on the side
of 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 driving stability, 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. Use the 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 tire 4
, at least once a month and before long trips.
Volvo strongly recommends buying a reliable air pressure gauge, as the automatic gauges provi-ded at service stations may be inaccurate.
WARNING
• Under-inflation is the most common cause 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 tiresInflation pressure should be checked when thetires are cold. The tires are considered to be cold when they have the same temperature as the surrounding(ambient) air. This temperature is normally reached after the vehicle 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 does the 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 are warm, 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.Related information
