WARNING
Risk of accident and injury caused by an insufficiently secured
vehicle rolling away
If the vehicle is not securely parked sufficiently, it can roll away in an
uncontrolled way even at a slight downhill gradient.
#
On uphill or downhill gradients, turn the front wheels so that
the vehicle rolls towards the kerb if it starts moving.
#
apply the parking brake.
#
Switch the transmission to position j.
&
WARNING
Risk of accident caused by the vehicle rolling away on major uphill
gradients
When the vehicle is being driven uphill or downhill, the service brakes
are additionally assisted by the electric motors of the drive system. This
ensures hold even on gradients exceeding 50%.
If you stop and change to transmission position i or j or switch off
the vehicle, the drive system will no longer provide any assistance.
On gradients exceeding 50%, the vehicle can roll away despite an
engaged parking brake and the transmission in park position j, unless
adequately secured.
Stopping on gradients exceeding 50%:
#
Before switching off the vehicle or changing to transmission
position i or j, additionally secure the vehicle against roll‐
ing away, e..g. with a wheel chock or object without sharp
edges.
When driving on uphill or downhill gradients, a significant proportion of the
brake force will be generated by the electric motors of the drive system.
Depending on whether the gradient is uphill or downhill, the supporting power
of the drive system will be shown on the driver display as either tractive power
or recuperation.
