WARNING
Never turn off the engine while the vehicle is moving, e.g. when driving downhill. Thisdeactivates certain important systemssuch as power steering and brakes.
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 mainte-nance schedule.

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driv-ing long distances.
Check that
the engine is running properly and that fuel consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning properly
all lights are working
‒ adjust the head-
light height if the vehicle is carrying aheavy load
tire tread depth and air pressure are atcorrect levels. Change to snow tires whendriving in areas where there is a risk ofsnowy or icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to makesure it can be driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50% antifreeze. This mixture helps pro-tect the engine from frost erosion down toapprox. –35 °C (–31 °F). Do not mix dif-ferent types of antifreeze as this couldpose a health risk.
Keep the fuel tank well filled to preventcondensation from forming.
Check the viscosity of the engine oil. Oilwith low viscosity (thinner oil) improvescold-weather starting and reduces fuelconsumption when driving with a coldengine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
Check the condition and charge level of the start battery. Cold weather placesgreater demands on the start battery andreduces its capacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in thewasher fluid reservoir.

The layout of the engine compartment may vary depending on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driv- er's side)
Washer fluid filler pipe 12
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located at the front of the engine compartmentbehind the radiator) may start or continuerunning automatically up to about6 minutes after the engine is turned off. Always entrust engine washing to a work- shop – an authorized Volvo workshop isrecommended. If the engine is hot, there isa risk of fire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicleelectrical system should always be in igni-tion mode
0 when work in being per-
formed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system isin ignition mode II or when the engine is
warm.
