STARTING AND DRIVING
}}
455
•
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.
•
Whenever possible, avoid using the vehicle to
drive short distances. The engine does not
have time to reach a normal operating tem-
perature 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 con-
sumption - consult a retailer for advice on
suitable tires.
•
Remove unnecessary items from the vehicle
- 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 deac-
tivates 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 maintenance sched-
ule.

Preparing for a long trip
It is important to have the vehicle's systems and
equipment checked carefully before driving 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 optimally
•
all lights are working ‒ adjust the headlight
height if the vehicle is carrying a heavy load
•
tire tread depth and air pressure are at cor-
rect levels. Change to snow tires when driv-
ing in areas where there is a risk of snowy or
icy roads
•
the start battery is sufficiently charged
•
the wiper blades are in good condition
