Trip computer The trip computer registers and calculates infor- mation such as distance driven, fuel consump-tion and average speed. This information is dis-played in the instrument panel.
To help promote fuel efficient driving, the trip computer provides readings for current and aver-age fuel consumption. The trip computer includes the following gauges:
• Trip odometers
• Odometer
• Current fuel consumption
• Distance to empty
• Tourist (alternative speedometer)
Trip odometerThere are two trip odometers: TM and TA. Duringa drive, the trip odometer registers:
• Mileage
• Driving time
• Average speed
• Average fuel consumption
The values displayed are those since the lasttime the trip odometer was reset.
OdometerThe odometer registers the vehicle's total mile-age and cannot be reset.
Current fuel consumptionThis gauge shows the current fuel consumption.This reading is updated once a second.
Distance to emptyThis function shows the approximate distancethat can be driven on the fuel remaining in thetank. The calculation is based on average fuel con- sumption during the last 20 miles (30 km) ofdriving and the amount of fuel remaining in thetank. When the gauge displays "----", there is very little useable fuel remaining in the tank; refuel as soonas possible. The accuracy of this figure may vary if your driv- ing style changes. An economical driving style willgenerally increase this distance.
Tourist (alternative speedometer)This is an alternative digital speedometer can beused when driving in areas in which the speedlimit is listed in a different unit of measure. If the speedometer is in mph, this gauge will show the
vehicle's speed in km/h and vice versa.

Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and that fuel consumption and the oil level are normal.
• Check for fuel, oil, and fluid leakage.
• Have the transmission oil level checked.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (including the sparetire where applicable), and replace those thatare worn. Also, check tire inflation pressure.
• The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to drivein countries where it may be difficult toobtain the correct fuel. •
Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can 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 engine's Eco function can helpimprove fuel economy.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold).

STARTING AND DRIVING
340•
Remove snow tires when threat of snow or ice 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 others are checked at the standard maintenance inter-vals.
Handling and roadholding
• 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 thatcapacity weight or maximum permissible axleloads are not exceeded.
• At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned more than might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.
Driving through standing 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 17.7 in. (45 cm) at walk-ing speed to help prevent water from enteringthe differential and the transmission. Thisreduces the oil's lubricating capacity and mayshorten the service life of these components.
• Take particular care when driving through flowing water.
• After driving through water, apply the brakesand check that they are functioning correctly.
• 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.

STARTING AND DRIVING
342•
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 bedamaged. It is therefore advisable to check the 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.

ECO drive mode
The Eco drive mode is a function designed to give the driver the opportunity to drive more eco-nomically and to help reduce fuel consumption.
When this mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points
• The engine management system and accel- erator pedal response
• Eco Coast functionality is activated: enginebraking is disabled at speeds betweenapprox. 40 and 85 mph (65 and 140 km/h)
• Climate system settings: certain functionswill be temporarily reduced or deactivated
• The suspension's self-leveling function
* low-
ers ground clearance to help reduce windresistance
• Information is shown in an ECO gauge in theinstrument panel to help promote more eco-nomical driving
NOTE
When Eco is activated, several climate system parameters are changed and the function ofcertain current-consuming systems will bereduced. Some of these functions can be restarted manually but full functionality will not berestored until Eco is deactivated.
Selecting ECO modeWhen the engine is switched off, ECO mode is deactivated and must be reactivated each time the engine is started.
ECO will appear in the
instrument panel when the function is activated.

mode can also be selected by tapping its button on the center display.
Eco CoastEco Coast essentially deactivates engine braking,allowing the vehicle to roll freely. When the driver releases the accelerator pedal, the transmission is automatically disengagedfrom the engine to allow the vehicle to roll as faras possible, which helps reduce fuel consump-tion. This feature is primarily intended to be used in driving situations where the vehicle can roll freely,such as down gentle hills or when a decrease inspeed is expected, such as when approaching anintersection or a traffic light. Eco Coast enables proactive driving with as little braking as possible. Depending on the driving situation, Eco and Eco Coast can be used in different ways to helpreduce fuel consumption: • With Eco activated
: this enables Eco Coast,
which allows the vehicle to roll freely for as
far as possible when the driver releases the
accelerator pedal (e.g., when approaching a traffic light or intersection).
or
• With Eco deactivated
: engine braking can
be used when the vehicle will only roll for
