Engine temperature
Engine overheating can result from low oil or coolant levels, towing or hard driving at high heatand altitude, or mechanical malfunction. Engineoverheating will be signaled with text and a redwarning triangle in the middle of the instrumentdisplay. The exact text will depend on the degree of overheating. It may range from
High engine
temp Reduce speed to High engine temp
Stop engine. If appropriate, other messages,
such as Coolant level low, Stop safely will
also be displayed. If your engine does overheat so that you must stop the engine, always allowthe engine to cool before attempting to check oiland coolant levels. See Engine compartment – coolant (p. 332) for more information.
Fault in brake system
If this symbol lights, the brake fluid level may be too low. Stop the vehicle in a safe place andcheck the level in the brake fluid reservoir, seeEngine compartment – brake fluid (p. 333). If the level in the reservoir is below MIN, the vehicle
should be transported to an authorized Volvo workshop to have the brake system checked. If the
and symbols come on at
the same time, there may be a fault in the brake force distribution system. 1. Stop the vehicle in a safe place and turn off
the engine.
2. Restart the engine.
• If both symbols extinguish, continue driving.
• If the symbols remain on, check the level inthe brake fluid reservoir, see Engine com-partment – brake fluid (p. 333). If the brakefluid level is normal but the symbols are stilllit, the vehicle can be driven, with great care,to an authorized Volvo workshop to have thebrake system checked.
• If the level in the reservoir is below
MIN, the
vehicle should be transported to an author-ized Volvo workshop to have the brake sys-tem checked.
WARNING
• If the fluid level is below the
MIN mark in
the reservoir or if a warning message is displayed in the text window: DO NOT
DRIVE . Have the vehicle towed to a
trained and qualified Volvo service techni- cian and have the brake system inspec-ted.
• If the
and symbols are
on at the same time, there is a risk of reduced vehicle stability.
Warning symbol
The red warning symbol lights up to indicate a problem related to safety and/or drivability. Amessage will also appear in the instrument panel.The symbol remains visible until the fault hasbeen rectified but the text message can be cleared with the OK button, see Information dis-
play – menu controls (p. 108). The warning sym- bol can also come on in conjunction with othersymbols. Action:
1. Stop in a safe place. Do not drive the vehicle further.
2. Read the information on the display. Imple- ment the action in accordance with the mes- sage in the display. Clear the message using OK.

Driving in cold weather
Check your vehicle before the approach of cold weather.
The following advice is worth noting:
• Make sure that the engine coolant (p. 332) contains 50 percent antifreeze. Any othermixture will reduce freeze protection. Thisgives protection against freezing down to–31 °F (–35 °C). The use of "recycled" anti-freeze is not approved by Volvo. Differenttypes of antifreeze 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, see Snowtires/studded tires (p. 306).
• To prevent the washer fluid (p. 344)reservoirfrom freezing, add washer solvents contain-ing antifreeze. This is important since dirt isoften splashed on the windshield during win-ter driving, 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.
Refueling – fuel requirements
Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (detergent
additives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddrivability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo does not recommend the use of exter- nal fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. andCanadian regulations require that pumps deliver-ing unleaded gasoline be labeled "UNLEADED".Only these pumps have nozzles which fit yourvehicle's filler inlet. It is unlawful to dispense lea-ded fuel into a vehicle labeled "unleaded gaso-line only". Leaded gasoline damages the three-way catalytic converter and the heated oxygensensor system. Repeated use of leaded gasolinewill lessen the effectiveness of the emission con-trol system (p. 281) and could result in loss ofemission warranty coverage. State and local vehi-

Some of the above mentioned items and others are checked at the standard maintenance inter-vals.
WARNING
Driving with the trunk open:
Driving with the
trunk open could lead to poisonous exhaust gases entering the passenger compartment. Ifthe trunk must be kept open for any reason,proceed as follows:
• Close the windows
• Set the ventilation system control to air flow to floor, windshield and side windowsand the blower control to its highest set-ting.
Handling and roadholdingAt the specified curb weight your vehicle has atendency to understeer, which means that thesteering wheel has to be turned more than mightseem appropriate for the curvature of a bend.This ensures good stability and reduces the riskof rear wheel skid. Remember that these proper-ties can alter with the vehicle load. The heavierthe load in the trunk, the less the tendency toundersteer. • Vehicle load, tire design and inflation pres- sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so that capacity weight or maximum permissible axleloads are not exceeded.

Towing a trailer When towing a trailer, always observe the legal requirements of the state/province.
NOTE
For the maximum trailer and tongue weights recommended by Volvo, see Weights (p. 371)
•
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, see the tire inflation decal on thedriver's door opening.
• 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.

MAINTENANCE AND SERVICING
332
Engine compartment – coolant
Normally, the coolant does not need to be changed. If the system must be drained, consulta trained and qualified Volvo service technician.
Level check and filling
Location of the coolant reservoir
See Fuel tank volume – specification and volume (p. 377) for information on cooling systemcapacities.
CAUTION
• If necessary, top up the cooling system with Volvo Genuine Coolant/Antifreezeonly (a 50/50 mix of water and anti-freeze).
• Different types of antifreeze/coolant maynot be mixed.
• If the cooling system is drained, it shouldbe flushed with clean water or premixedanti-freeze before it is refilled with thecorrect mixture of water/anti-freeze.
• The cooling system must always be keptfilled to the correct level, and the level must be between the
MIN and MAX
marks. If it is not kept filled, there can be high local temperatures in the enginewhich could result in damage. Checkcoolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and has alower boiling point. It can also causedamage to the cooling system if it shouldfreeze.
• Do not use chlorinated tap water in thevehicle's cooling system.
• If there is coolant under the vehicle, if youdetect coolant fumes or if it necessary totop up with more than approx. 2 qts (2 lit-ers) of coolant, engine damage could
occur if the vehicle is driven. Have it towed to an authorized Volvo workshop.
WARNING
• Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
