Electric parking brake
General notes
G WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.

In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is a malfunction
in the system, it may not be possible to apply
the released parking brake.

If this is the case, only park the vehicle on
level ground and secure it to prevent it roll-
ing away.

tion P.
It may not be possible to release an applied
parking brake if the on-board voltage is low or

tion test at regular intervals while the engine
