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 cargo compartment.

WARNING
• The cooling fan (located at the front of the engine compartment, behind the radi-ator) may start or continue to operate (forup to 6 minutes) after the engine hasbeen switched off.
• Engine cleaning should only be done by aworkshop. If engine cleaning agents areused when the engine has been running,there may a fire risk.
• Before performing any operations in theengine compartment, the ignition shouldalways be completely switched off (in mode
0) and there should be no remote
keys in the passenger compartment. Thegear selector should be in the P (park)
position. If the engine has been running, wait until it has cooled before touchingany components in the engine compart-ment.
• The distributor ignition system operatesat very high voltages. Special safety pre-cautions must be followed to preventinjury. Always turn the ignition off whenreplacing distributor ignition componentse.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintended move-ments and body injury.

* Option/accessory.521
Lift the rubber strip by pressing it inward in the engine compartment.
Remove the plastic cover by folding out the catch and lifting the cover upward.
Unscrew the expansion tank cap and add coolant. The level should be between the MIN and MAX marks on the tank.
Put the other components back in place in the reverse order.
CAUTION
• High levels of chlorine, chlorides and other salts may cause corrosion in thecooling system.
• Only use coolants with corrosion protec-tion recommended by Volvo.
• The ratio of coolant to water is 50/50.
• Mix the coolant with tap water of drinka-ble quality.
• If maintenance is performed on the cool-ing system or if the coolant is replaced,flush the cooling system with clean waterbefore adding new a new coolant/watermixture.
• The engine may only be operated with aproperly filled cooling system. Otherwise,high temperatures and cracks in the cyl-inders may occur.

Refilling the windshield washer fluid reservoir
Washer fluid helps keep the windshield and headlights clean.
The windshield and headlight washers * share a
common reservoir. Open the blue cap to refill washer fluid (see the illustration for the locationof the reservoir). During cold weather, the reservoir should be filled with windshield washer solvent containing anti-freeze. Use Volvo Original Washer Fluid or theequivalent with a recommended pH valuebetween 6 and 8 in a 1:1 solution. When there is approx. 1 qt (1 liter) of washer fluid remaining in the reservoir, a text message and the
symbol will be displayed in the
instrument panel.
