General
Economical driving
Driving economically means driving smoothly
while thinking ahead and adjusting your driving
style and speed to the prevailing conditions.
•
Drive in the highest gear possible, adapted
to the current traffic situation and road -
lower engine speeds result in lower fuel
consumption.
•
Avoid driving with open windows.
•
Avoid sudden unnecessary acceleration
and heavy braking.
•
Remove unnecessary items from the car -
the greater the load the higher the fuel con-
sumption.
•
Use engine braking to slow down, when it
can take place without risk to other road
users.
•
A roof load and ski box increase air resis-
tance, leading to higher fuel consumption
- remove the load carriers when not in use.
•
Do not run the engine to operating tem-
perature at idling speed, but rather drive
with a light load as soon as possible - a
cold engine consumes more fuel than a
warm one.
•
Cars with the D5 engine and 6-speed man-
ual transmission are started in 2nd gear
under normal conditions on level ground.
For more information and further advice, see
page 11.
WARNING
Never switch off the engine while moving,
such as downhill, this deactivates important
systems such as the power steering and
brake servo.
Driving in water
The car can be driven through water at a maxi-
mum depth of 25 cm at a maximum speed of
10 km/h. Extra caution should be exercised
when passing through flowing water.
During driving in water, maintain a low speed
and do not stop the car. When the water has
been passed, depress the brake pedal lightly
and check that full brake function is achieved.
Water and mud for example can make the
brake linings wet resulting in delayed brake
function.
•
Clean the electric contacts of the electric
engine block heater and trailer coupling
after driving in water and mud.
•
Do not let the car stand with water over the
sills for any long period of time - this could
cause electrical malfunctions.
IMPORTANT
Engine damage can occur if water enters
the air filter.
In depths greater than 25 cm, water could
enter the transmission. This reduces the
lubricating ability of the oils and shortens
the service life of these systems.
In the event of the engine stalling in water,
do not try restart - tow the car from the water
to a workshop - an authorised Volvo work-
shop is recommended. Risk of engine
breakdown.
Engine, gearbox and cooling system
Under special conditions, for example hard
driving in hilly terrain and hot climate, there is
a risk that the engine and drive system may
overheat - in particular with a heavy load.
For information about overheating when driv-
ing with a trailer, see page 225.
•
Remove any auxiliary lamps from in front
of the grille when driving in hot climates.
•
If the temperature in the engine's cooling
system is too high the instrument panel's
warning symbol is illuminated and there is
a text message displayed there
High
engine temp Stop safely - stop the car in
a safe way and allow the engine to run at
idling speed for several minutes to cool
down.
