Have the vehicle converted to cold-resistant
service products at a qualified specialist work-
shop.
Remember to fill the vehicle fuel tank with win-
ter diesel fuel when it is time to do so.
i
If the vehicle is mainly operated at very low
temperatures, the maintenance intervals are
reduced.
Coolant preheater
The coolant preheater consists of an electrical
heating element that is installed in the engine
crankcase. The coolant preheater is operated at
230 V independently of the vehicle's electrical
system.
i You can have the basic wiring for the coolant
preheater retrofitted at a qualified specialist
workshop.
Notes before attempting a cold start
! The fluid in discharged batteries may freeze
at extremely cold temperatures. Do not rapid-
charge cold batteries. Otherwise, you could
damage the batteries.
Special measures must be taken before a cold
start if the vehicle has been exposed to
extremely low temperatures.
X Charge discharged batteries before starting.
i The capacity of the batteries is adversely
affected by increasingly cold temperatures.
X
Thaw frozen batteries before charging them.
Starting the engine
! If the ignition lock is switched to the drive
position and you notice a low battery voltage
or an event window shows the
#
symbol,
do no start the engine. A starting attempt
could damage the batteries if they are cold or
not fully charged.
!
The lubricity of the engine oil and transmis-
sion oil may be reduced at very low outside
temperatures. Driving a cold vehicle may
result in damage to the drivetrain and assem-
blies.
! If a warning tone sounds and the red event
window with the
5
symbol appears in the
on-board computer, the operating safety of
the engine is jeopardised.
Do not pull away, or stop the vehicle as soon
as possible, paying attention to road and traf-
fic conditions. You could otherwise damage
the engine.
