08 Starting and driving
Driving in water
Overheating
IMPORTANT
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
caution.
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.
Engine damage can occur if water enters
the air filter.
In depths greater than 25 cm (30 cm with
XC70), water could enter the transmission.
This reduces the lubricating ability of the
oils and shortens the service life of these
systems.
The car can be driven through water at a
maximum depth of 25 cm (30 cm with XC70)
at a maximum speed of walking pace. Extra
caution must be exercised when passing
through flowing water.
For information about overheating when driv-
ing with a trailer, see Driving with a trailer*
(p. 311).
Damage to any component, engine, trans-
mission, turbocharger, differential or its
internal components caused by flooding,
hydrostatic locking or oil shortage, is not
covered by the warranty.
Remove any auxiliary lamps from in front
of the grille when driving in hot climates.
•
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 the temperature in the engine's cooling
•
system is too high then a warning symbol
is illuminated in the combined instrument
panel's information display and a text
message High engine temperature
Stop safely is shown there - stop the car
in a safe way and allow the engine to run
at idling speed for several minutes in
order to cool down.
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.
If necessary, clean the contacts for the
electric heater and trailer coupling after
driving in water and mud.

then the engine must be switched off
after stopping the car.

Towing (p. 318)
Do not let the car stand with water over
the sills for any long period of time - this
could cause electrical malfunctions.

In the event of overheating in the gearbox
a built-in protection function is activated
which, amongst other things, illuminates
a warning symbol in the combined instru-
ment panel, and its display shows the
text message Transmission hot Reduce
speed or Transmission hot Stop safely
Wait for cooling - follow the recommen-
dation given and lower the speed and
