Overheating the engine and transmission
In demanding driving conditions, such as when transporting heavy loads, driving in mountainousareas or in very hot weather there is a risk ofoverheating the engine or transmission.
• The engine's output may be slightly limited if there is a risk of overheating.
• Remove e.g., auxiliary lights mounted in frontof the grille in hot weather.
• If the temperature of the engine coolantbecomes too high, the warning symbol will illuminate and the message
Engine
temperature/Stop safely will be displayed.
Stop the vehicle as soon as possible in a safe place and let the engine idle for severalminutes.
• If the message
Engine temperature/High
temperature Turn off engine or Engine
coolant/Stop safely is displayed, stop
safely and turn off the engine.
• If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also by activated, the warning symbol will illuminate and the message
Transmission
warmHigh temperature Reduce speed
or Transmission warmStop safely, wait
for cooling will be displayed in the instru-
ment panel. •
The air conditioning may be switched off temporarily.
• After a prolonged period of driving, do notturn off the engine immediately after stop-ping.
• The engine cooling fan commonly continuesto run for several minutes after the enginehas been turned off.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator) maystart or continue to operate (for up to6 minutes) after the engine has beenswitched off.

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.

Driving with a trailer
When towing a trailer, always observe the legal requirements of the state/province.
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
• Increase tire pressure to recommended fullpressure.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
• If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy. •
It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
•
When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.

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. Volume:
• Models
with headlight washers: 5.8 qts
(5.5 liters).
• Models
without headlight washers: 3.7 qts
(3.5 liter).
