Economical driving
Drive economically and environmentally con- scious by thinking ahead, avoiding rapid startsand stops and adapting driving style and speedto the current traffic conditions.
Driving economically conserves natural resources
Observe the following rules:
• Do not warm up the engine by idling. It is better to begin driving normally immediately after starting the engine. A cold engine uses more fuel than a warm engine and is subject to increased wear.
• Whenever possible, avoid using the vehicle todrive short distances. The engine does nothave time to reach a normal operating tem-perature and this leads to increased fuelconsumption.
• Maintain a steady speed and a generous fol-lowing distance to traffic ahead to minimizebraking.
• For lower fuel consumption, activate Ecodrive mode.
• Use the Eco Coast function in drive mode Eco - engine braking is deactivated, allowing the vehicle's kinetic energy to be used to rollgreater distances.
• Use gear
D as often as possible and avoid
using the kick-down function. •
Fuel consumption is increased at highspeeds - air resistance increases with speed.
• Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
• Maintain the correct pressure in the tires andcheck pressure regularly.
• The type of tires used could affect fuel con-sumption - consult a retailer for advice onsuitable tires.
• Do not use winter tires after the winter sea-son has ended.
• Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
• Avoid driving with the windows open.
• Using the trip computer's fuel consumptionindicators can help you learn how to drivemore economically.
Other factors that decrease fuel
consumption
• Dirty air cleaner.
• Dirty engine oil and clogged oil filter.
• Incorrect front-end alignment.
• Incorrect wheel alignment.
Some of the above items and others are checked as part of Volvo's standard maintenance sched-ule.

Engine compartment overview
This overview shows some service-related com- ponents.
The layout of the engine compartment may vary depend- ing on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driver's side)
Washer fluid filler pipe 11
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located at the front of the engine compartment behindthe radiator) may start or continue runningautomatically up to about 6 minutes after theengine is turned off. Always entrust engine washing to a workshop – an authorized Volvo workshop is recom-mended. If the engine is hot, there is a risk offire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicle electrical system should always be in ignition mode
0
when work in being performed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system is in igni- tion mode II or when the engine is warm.

Engine oil
For the recommended service intervals and war- ranties to be applied, an approved engine oilmust be used.
Volvo recommends:
11 Fill the washer fluid at regular intervals, e.g. when refueling.

MAINTENANCE AND SERVICE
560If the engine oil is not checked regularly and the level becomes low, this could cause seriousengine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filledwith a specially adapted synthetic engine oil.Great care has been put into the choice of oil,with consideration given to service life, starta-bility, fuel consumption and environmentalimpact. For the recommended service intervals to apply, an approved engine oil must be used.Only use the prescribed oil grade to top off orchange the oil. Otherwise, there is a risk ofthe vehicle's service life, startability, fuel con-sumption and environmental impact beingaffected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low. Onengine variants with an oil pressure sensor, a
warning symbol is displayed in the instrument panel when oil pressure is low
. On engine
variants with an oil level sensor, the
warn-
ing symbol in the instrument panel and display messages are used to alert the driver. Someengine variants have both systems. Contact aVolvo retailer for more information. Change the engine oil and oil filter according to the schedule specified in the Warranty and Main-tenance Records Information booklet. Oils of ahigher grade than that specified may be used. Ifthe vehicle is driven in adverse conditions, Volvorecommends using an oil with a higher gradethan that specified.

Fuse pliers are provided on the inside of the fuse box cover to assist in removing and insertingfuses. There are also spaces for several extra fuses in the fusebox.
PositionsThere is a decal with a diagram of the locationsof the fuses on the inside of the cover.
• Fuses 1-13, 18-30, 35-37 and 46-54 are"Micro" fuses.
• Fuses 14-17, 31-34 and 38-45 are"MCase" fuses and should only be replaced by a workshop 21
