WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle. Do not use Pilot Assist in demanding driving conditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps. In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog, slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations: • High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override PilotAssist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills. Thedriver should be attentive and prepared to applythe brakes in these situations. Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
Additional information
•
The Off Road drive mode cannot be
selected if Pilot Assist is activated.
• Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.

STARTING AND DRIVING

Winter driving
Check your vehicle before the approach of cold weather.
The following advice is worth noting:
• Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture willreduce freeze protection. This gives protec-tion against freezing down to –31 °F(–35 °C). The use of "recycled" antifreeze isnot approved by Volvo. Different types ofantifreeze must not be mixed.
• Volvo recommends using only genuine Volvoantifreeze in your vehicle's radiator.
• Try to keep the fuel tank well filled – thishelps prevent the formation of condensationin the tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
• The viscosity of the engine oil is important.Oil with low viscosity (thinner oil) improvescold-weather starting as well as decreasingfuel consumption while the engine is warm-ing up. Full synthetic 0W-30 oil is recom-mended for driving in areas with sustainedlow temperatures.
• The load placed on the battery is greater dur-ing the winter since the windshield wipers,lighting, etc., are used more often. Moreover,the capacity of the battery decreases as thetemperature drops. In very cold weather, apoorly charged battery can freeze and be damaged. It is therefore advisable to checkthe state of charge more frequently andspray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tires onall four wheels for winter driving.
• To prevent the washer fluid reservoir fromfreezing, add washer solvents containingantifreeze. This is important since dirt is oftensplashed on the windshield during winterdriving, requiring the frequent use of thewashers and wipers. Volvo Washer Solventshould be diluted as follows: Down to 14 °F(–10 °C): 1 part washer solvent and 4 partswater Down to 5 °F (–15 °C): 1 part washersolvent and 3 parts water Down to 0 °F(–18 °C): 1 part washer solvent and 2 partswater Down to –18 °F (–28 °C): 1 partwasher solvent and 1 part water.
• Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.

Towing eyelet
When used, the towing eyelet should always be securely attached in the openings on the rightside of the front and rear bumpers. There arecovers over these attachment points.
Using the towing eyelet
Take out the towing eyelet, which is stored under the floor in the trunk.

Loading specifications Properly loading your vehicle will provide maxi- mum return of vehicle design performance.
Weight designations
Before loading your vehicle, familiarize yourself with the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
Permissible axle weight
The maximum allowable weight that can be car- ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load Limit
1. Locate the statement "the combined weightof occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driver and passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.
WARNING
• Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.
