STARTING AND DRIVING
290
Outside temperature
The electric motor, electronics and batteries work
best at approx. 25 °C. When the car is connected
to an electrical socket it is conditioned (p. 138)
to its optimal temperature range. If the car is
started in cold weather or goes beyond its per-
mitted temperature range while driving then the
fuel heater starts and, if required, the internal
combustion engine starts automatically so that
heating takes place. The car can be driven elec-
trically but with reduced power if the temperature
becomes too low.
Similarly, the system may need to be cooled
down when driving in hot conditions.
NOTE
If the outside temperature drops extremely
low then the diesel engine will always be run-
ning.
Power consumers
The more power consumers in the car that are
switched on (e.g. stereo, electrically heated win-
dows, door mirrors, seats, etc.) the higher the
energy consumption.

Driving in water
Driving in water means that the car is driven
through deep water on a water-covered road-
way. Fording must be carried out with great cau-
tion.
The car can be driven through water at a maxi-
mum depth of 25 cm at a maximum speed of
walking pace. Extra caution must 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.
•
If necessary, clean the contacts for the elec-
tric 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 lubri-
cating ability of the oils and shortens the
service life of these systems.
Damage to any component, engine, transmis-
sion, turbocharger, differential or its internal
components caused by flooding, hydrostatic
locking or oil shortage, is not covered by the
warranty.
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 workshop is
recommended. Risk of engine breakdown.
