Volvo XC90 Owner's Manual page 429

The trip computer's current fuel consump-
•
tion indicator can help promote more fuel-
efficient driving.
Do not warm up the engine by idling. It is
•
better to begin driving normally immedi-
ately after starting the engine. A cold
engine uses more fuel than a warm
engine.
Whenever possible, avoid using the vehi-
•
cle to drive short distances. The engine
does not have time to reach a normal
operating temperature and this leads to
increased fuel consumption.
Use engine braking to brake the vehicle,
•
when this is safe for other road users.
Maintain the correct pressure in the tires
•
and check pressure regularly.
The type of tires used could affect fuel
•
consumption - consult a retailer for advice
on suitable tires.
Remove unnecessary items from the vehi-
•
cle - the heavier the load, the higher the
fuel consumption.
Roof loads increase air resistance and
•
increase fuel consumption. Remove roof
boxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
•
WARNING
Never turn off the engine while the vehicle
is moving, e.g. when driving downhill. This
deactivates certain important systems
such 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.

STARTING AND DRIVING
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 a
heavy load

•
correct levels. Change to snow tires when

snowy or icy roads
the start battery is sufficiently charged
