WARNING
• When refilling with oil, make sure no oil falls onto hot engine parts.
Failure to comply could result in fire.

lytic converter or the engine. Contact a qualified workshop to drain the engine
oil if necessary.
• No additives should be used with engine oil. Any damage caused by the
use of such additives would not be covered by the factory warranty.
For the sake of the environment
• Oil must not be disposed of in the drain or on the ground.
• Always observe legal requirements when disposing of empty oil

Cooling system
Coolant fluid
The purpose of the coolant fluid is to carry heat away from the
engine. The correct amount of antifreeze is decisive in
preventing the cooling system from freezing in winter.
The vehicle's engine cooling system is filled for life at the factory, so no
coolant needs to be changed. The coolant fluid consists of a mixture of water
and antifreeze G12++. This is a glycol-based antifreeze with anti-corrosion
additives.
Coolant fluid additive
The amount of antifreeze required depends on the temperatures to be
expected in the winter season. If the antifreeze concentration is too low the
coolant can freeze, resulting in failure of the cooling system and heater.
