WARNING
When the ABS system is malfunctioning, the wheels may lock during hard braking, reducing steering capability and extending the braking distance.
When the ABS is switched off due to a malfunction, the ESP ®
is also switched off. The basic
driving and braking functions are still available.
The risk of your vehicle skidding is then increased in certain situations. You should
therefore always adapt your speed and driving style to the prevailing road and weather
conditions. Problem Possible causes/consequences and

smart center. G
WARNING
If the SRS indicator lamp does not come on when you switch on the ignition or does not go out again after a few seconds once the drive system is running or comes on again, the supple-
mental restraint systems are malfunctioning.
In the event that a malfunction of the SRS is indicated as described in scenario 2, the SRS may
not be operational. For your safety, we strongly recommend that you contact an authorized
electric drive smart center immediately to have the system checked; A malfunctioning SRS system may not deploy when needed in an accident resulting in serious or fatal injury, or it
might deploy unexpectedly and unnecessarily which could result in an accident and/or
injury to you or to others.
! If the SRS indicator lamp comes on while driving, have the system checked at an
authorized electric drive smart center immediately.
It is possible that the air bag and the emergency tensioning device could be activated
unintentionally or will not function in the event of an accident.
