Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly
involving the electrical, fuel or distributor ignition systems, may cause unusually
high threeway catalytic converter temperatures...
The electrical functions in the vehicle drain the battery to varying degrees.
Avoid using ignition mode II when the engine is switched off. Use ignition mode
I instead, as this uses less electrical current...
Other information:
Passing assistance can be used with Adaptive Cruise Control* or Pilot Assist*.
Several conditions must be met for passing assistance to be possible.
In order to activate passing assistance:
your vehicle must be following a vehicle ahead (target vehicle)
your vehicle's current speed must be at least 70 km/h (43 mph)
the set speed must be high enough to safely pass another vehicle...
The vehicle has a flexible cargo compartment that makes it possible to carry
and secure large objects.
The cargo compartment capacity can be considerably increased by folding down
the backrests in the second and third rows* of seats. To make loading and unloading
easier, the rear section of the vehicle can be raised and lowered using the level
control function*...
