Settingthevehicle level
&WARNINGRisk of accident becausevehicle level istoo high
Ifyou drive at a highervehicle level,the driv‐ingcharacteristics may be impaired duetothe highervehicle center of gravity.
Thevehicle can drift outwards,forexample,whensteering or cornering.
#Alwayschoose avehicle level which issuitedtothe drivingstyle andtheroadsurface conditions.
&WARNINGRisk of entrapment fromvehi‐cle lowering
When loweringthevehicle, people couldbecome trapped iftheir limbs are betweenthevehicle body andthe tires or underneaththevehicle.
