쮿

Take the car to a qualified 
specialist workshop, e.g. a smart 
center, without delay.

 when the abs system fails, together 

with the brake system indicator light.

쮿

Call a breakdown recovery service 
such as smartmove Assistance or a 
qualified specialist workshop 
such as a smart center.

Accident risk!
If the abs system is faulty, the 

wheels could lock when the brakes are 
applied. If this happens, the car's 
steerability will deteriorate and the 
braking distance may increase. esp 
also will not function if the abs system 
is having problems. 

There will then be an increased risk of 
the vehicle skidding in certain 
driving situations. Always therefore 
adapt your driving style to the 
prevailing road, traffic and weather 
conditions.

Airbag indicator light
The airbag indicator light signals to you 
that there is a fault in the safety systems 
of the:

 airbags,

 belt tensioners,

 child seat recognition.

>Note!

and additional information to this

Airbag indicator light
It lights up:

 with the ignition switched on.
The subsequent self
diagnosis of the 
safety systems yields the following 
results:
1. Airbag indicator light goes out after a 
maximum of 4 seconds:

> the airbag system is OK.

2. The airbag indicator light goes out 
after a maximum of 4 seconds for 
approximately 1 second, then it comes on 
again and stays on:

> A fault has been detected.

쮿

Do not sit on the front passenger's 
seat; this applies in particular to 
children.

쮿

Take the car to a qualified 
specialist workshop, e.g. a smart 
center, without delay.

Danger of injury!
If the indicator light does not 

come on when you switch the ignition 
on, or does not go out again after a few 
seconds once the engine is running or 
comes on again, there is a fault. There 
is the possibility of individual 
systems being activated 
unintentionally or not being triggered 
off in an accident involving a high rate 
of deceleration. In this instance, have 
the safety system checked and repaired 
immediately by a qualified specialist 
workshop. smart gmbh recommends that 
you visit a smart center for this. It is 
particularly important to have safety

relevant work and work on safety

relevant systems performed by a 
qualified specialist workshop.

Airbag indicator light
3. Airbag indicator light flashes for 
15 seconds:

> Special smart baby carrier on the 

passenger's seat has been 
recognised.

> Passenger's airbag and the side 

airbags* (if available) are 
deactivated.

Danger of injury!
If the airbag indicator light 

does not come on when a baby carrier is 
fitted to the passenger's seat, the 
passenger's airbag has not been 
deactivated. If the passenger's airbag 
has not been deactivated, a child could 
sustain serious or even fatal injuries 
in the event of the airbag on the 
passenger's side being triggered, 
particularly if the child is in the 
immediate vicinity of the passenger's 
airbag at the time of its activation.
The passenger's airbag is only 
deactivated when you fit an original 
smart baby carrier to the passenger's 
seat.

Danger of injury!
For this reason, you should never 

carry a child on the passenger's seat in 
a child restraint system that faces to 
the rear if the passenger's airbag has 
not been deactivated, i.e. if the airbag 
indicator light is not lit.
Also observe the corresponding 
warning sticker on the instrument 
panel.
If you have installed an original smart 
baby carrier on the passenger's seat 
and the airbag indicator light does not 
come on (restraint system not 
identified), have the automatic 
restraint system recognition function 
checked without delay by a qualified 
specialist workshop, such as a smart 
center.
Until this problem has been rectified, 
do not carry children in the car, as they 
could sustain serious or even fatal 
injuries in the event of an accident.
