•Triangular areas at the far sides of the windshield are not heated electricallyand will take slightly longer todefrost/de-ice.
• The heated windshield may affect theperformance/range of e.g., transpond-ers used to automatically pay highwaytolls or other communication equip-ment.
The following occurs when the defroster/ windshield heating functions have been acti-vated: •
Blower speed increases automatically and the air conditioning will switch on (ifnot already on and if the passenger com-partment blower is not turned off) todehumidify the air in the passenger com-partment. Air conditioning can beswitched off by pressing the
AC button.
• Recirculation will not function whiledefrost is engaged.
The climate system will return to its previous settings when the defroster/windshield heat-ing function is switched off. See also page 113 for additional information.
Recirculation/air quality system
RecirculationThis function can be used to shut out exhaust fumes,smoke, etc., from the pas-senger compartment. The airin the passenger compart-ment is then recirculated,i.e., no air from outside the
car is taken into the car when this function isactivated. The indicator light in the button willilluminate when recirculation is selected. If the air in the car recirculates for too long, there is a risk of condensation forming on theinsides of the windows, especially in winter.
TimerThe timer function minimizes the risk of fog- ging, or stale air when the recirculation func-tion is selected by automatically switching offthe function after a certain length of time,depending on the ambient temperature. Acti-vate/deactivate the function under

Remember that these properties can alter with the vehicle load. The heavier the load inthe cargo area, the less the tendency toundersteer.
Handling, roadholdingVehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the recom-mended pressure according to the vehicleload. See the "Tire pressure" section. Loadsshould be distributed so that capacity weightor maximum permissible axle loads are notexceeded.
Driving through water
•
The vehicle can be driven through water up to a depth of approximately 10 in.(25 cm), at a maximum speed of 6 mph(10 km/h).
• Take particular care when driving throughflowing water.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.
WARNING
•Avoid driving through standing or rushing water. Doing so can be dan-gerous and it may also be difficult todetermine the actual depth of thewater.
• If water cannot be avoided, after driv-ing through the water, press lightly onthe brake pedal to ensure that thebrakes are functioning normally. Wateror mud can make the brake liningsslippery, resulting in delayed brakingeffect.
CAUTION
• Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than 10 in (25 cm), water mayenter the differential and the transmis-sion. This reduces the oil's lubricatingcapacity and may shorten the servicelife of these components.
• Do not allow the vehicle to stand inwater up to the door sills longer thanabsolutely necessary. This could resultin electrical malfunctions.
• If the engine has been stopped whilethe vehicle is in water, do not attemptto restart it. Have the vehicle towedout of the water.
Engine and cooling systemUnder special conditions, for example when driving in hilly terrain, extreme heat or withheavy loads, there is a risk that the engineand cooling system will overheat. Proceed asfollows to avoid overheating the engine. •
Maintain a low speed when driving with a trailer up long, steep hills.
• Do not turn the engine off immediatelywhen stopping after a hard drive.

Fuel vapor expands in hot weather. Open the filler cap slowly. After refueling, close the fuel filler cap by turning it clockwise until it clicks into place.
CAUTION
•Do not refuel with the engine running 3
.
Turn the ignition off or to position I. If
the ignition is on, an incorrect reading could occur in the fuel gauge.
• Avoid overfilling the fuel tank. Do notpress the handle on the filler nozzlemore than one extra time. Too muchfuel in the tank in hot weather condi-tions can cause the fuel to overflow.Overfilling could also cause damage tothe emission control systems.
Emission controls
Three-way catalytic converter
•
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle ifyou detect engine misfire, noticeable lossof power or other unusual operating con-ditions, such as engine overheating orbackfiring. A properly tuned engine will

help avoid malfunctions that could dam- age the three-way catalytic converter.
• Do not park your vehicle over combusti-ble materials, such as grass or leaves,which can come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
• Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cat-alytic converter or exhaust system over-heating.
• Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehiclemay be illegal and can cause three-waycatalytic converter or exhaust systemoverheating. This includes: altering fuelinjection settings or components, alteringemission system components or locationor removing components, and/or repea-ted use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continu-ously monitors engine functions and controlsfuel injection. The ratio of fuel to air into theengine is continuously adjusted for efficientcombustion to help reduce harmful emis-sions.

WARNING
•Exceeding the permissible axle weight, gross vehicle weight, or any otherweight rating limits can cause tireoverheating resulting in permanentdeformation or catastrophic failure.
• Do not use replacement tires withlower load carrying capacities than thetires that were original equipment onthe vehicle because this will lower thevehicle's GVW rating. Use only tireswith the correct load carrying capacity.Consult your Volvo retailer for informa-tion.
