Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect onthe brake discs and pads. This will cause a delayin braking effect when the pedal is depressed. Toavoid such a delay when the brakes are needed,depress the pedal occasionally when drivingthrough rain, slush, etc. This will remove the waterfrom the brakes. Check that brake applicationfeels normal. This should also be done afterwashing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain whendriving in mountains or hilly areas, or when towinga trailer. Vehicle speed is usually slower, whichmeans that the cooling of the brakes is less effi-cient than when driving on level roads. To reducethe strain on the brakes, shift into a lower gearand let the engine help with the braking. Do notforget that if you are towing a trailer, the brakeswill be subjected to a greater than normal load.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.

STARTING AND DRIVING
271
Driving through water
The vehicle should be driven with extreme cau- tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to a depth of approximately 13 in. (35 cm) at walkingspeed to help prevent water from entering thedifferential and the transmission. Water reducesthe oil's lubricating capacity and may shorten theservice life of these components.
• 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 dangerous and itmay also be difficult to determine theactual depth of the water.
• If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.
CAUTION
•Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than approximately 13 in.(35 cm), water may enter the differentialand the transmission. This reduces theoil's lubricating capacity and may shortenthe service life of these components.
• Damage to any components, the engine,transmission, turbo-charger, differential orits internal components caused by flood-ing, vapor lock or insufficient oil is notcovered under warranty.
• Do not allow the vehicle to stand in waterup to the door sills longer than absolutelynecessary. This could result in electricalmalfunctions.
• If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water.

Engine and cooling system
Under special conditions, for example when driv- ing in hilly terrain, extreme heat or with heavyloads, there is a risk that the engine and coolingsystem will overheat.
Proceed as follows to avoid overheating the engine.
• Maintain a low speed when driving with atrailer up long, steep hills. For information,see Towing a trailer (p. 279)
• Do not turn the engine off immediately whenstopping after a hard drive.
WARNING
The cooling fan may start or continue to oper- ate (for up to 6 minutes) after the engine hasbeen switched off.
• Remove any auxiliary lights from in front of the grille when driving in hot weather condi-tions.
• Do not exceed engine speeds of 4500 rpm ifdriving with a trailer in hilly terrain. The oiltemperature could become too high.

NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Economical driving conserves natural
resources
Observe the following rules: • Bring the engine to normal operating tem- perature as soon as possible by driving witha light foot on the accelerator pedal for thefirst few minutes of operation. A cold engineuses more fuel and is subject to increasedwear.
• Whenever possible, avoid using the vehiclefor driving short distances. This does notallow the engine to reach normal operatingtemperature.
• Drive carefully and avoid rapid accelerationand hard braking.
• Use the transmission's Drive (
D) position as
often as possible and avoid using kick-down.
• Using the transmission's Sport mode mayincrease fuel consumption somewhat. Use the transmission's Drive (
D) position as often
as possible. For additional information about Sport mode, see Transmission – Geartronic(p. 254).
• Do not exceed posted speed limits. •
Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snow orice has ended.
• Note that roof racks, ski racks, etc, increaseair resistance and also fuel consumption.
• At highway driving speeds, fuel consumptionwill be lower with the air conditioning on andthe windows closed than with the air condi-tioning off and the windows open.
• Using the onboard trip computer's fuel con-sumption modes can help you learn how todrive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and othersare checked at the standard maintenance inter-vals.

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.
WARNING
Before performing any operations in the engine compartment, the ignition should always be completely switched off (in mode 0,
see Ignition modes (p. 80)) and there should be no remote keys in the passenger compart- ment. The gear selector should be in the P
(park) position. If the engine has been run- ning, wait until it has cooled before touchingany components in the engine compartment. The distributor ignition system operates at very high voltages. Special safety precautionsmust be followed to prevent injury. Alwaysturn the ignition off when:
• Replacing 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.

CAUTION
•If Oil service required is displayed, the
oil level may be too high. Take the vehicle to an authorized Volvo workshop as soonas possible.
• If the oil level sensor indicates that thelevel is too low, using the correct oil, topup with the amount of oil indicated assoon as possible, see oil specifica-tions (p. 375).
WARNING
Do not allow oil to spill onto or come into con- tact with hot exhaust pipe surfaces.
Electronically checking the oil level
The oil level should be checked at regular inter- vals, particularly during the period up to the firstscheduled maintenance service. To check the oil level:1.
Activate ignition mode II, see Ignition modes
(p. 80).
2. Turn the thumb wheel on the left steering wheel lever until
Oil level is displayed.
> The oil level will be displayed.
NOTE
• The system cannot detect changes in the oil level immediately. The vehicle must bedriven approximately 20 miles (30 km) orhave been parked on level ground withthe engine off for 5 minutes before theoil level reading will be correct.
• If the necessary conditions are not metfor checking the oil level electronically(time interval after the engine wasswitched off, if the vehicle is parked on an incline, etc.),
No values available will
be displayed. This does not indicate a
problem with the oil level sensor.
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.

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.
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.
Engine compartment – brake fluid
The brake fluid should always be between the MIN and MAX marks on the inside of the reser-
voir.
