NOTICE
●
Never drive with the tank completely
empty. Under certain circumstances, the en-
ergy stored in the high-voltage battery may
not be sufficient to reach the nearest service
station.
●
When the outside temperature is very low,
and therefore the high-voltage battery is
very cold, difficulties may arise in starting the
internal combustion engine and the range in
the electric driving mode may be reduced.

NOTICE
●
To ensure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm
also depends on the outside temperature. If
necessary, use the engine oil temperature as

●
Additional lights and other accessories in
front of the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
●
The front spoiler also ensures proper distri-
bution of the cooling air when the vehicle
is moving. If the spoiler is damaged this can
reduce the cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance.
