Pre-tensioner and Load Limiting
All seat belts are equipped with pre-tensioner and load
limiting systems.
In most moderate frontal or near frontal accidents, the
front airbag and all pre-tensioner systems will deploy
simultaneously.
The pre-tensioners take up slack in the seat belts as the
airbags are expanding. The load limiting system
releases belt webbing in a controlled manner to reduce
belt force on the passenger's chest.
In some moderate frontal or near frontal accidents,
only the pre-tensioner system will deploy.
Seat Belt Reminder
A warning symbol in the instrument cluster will
come ON and warning sound will be heard for
six seconds (approximately) when the ignition is
set to ON if the driver seat belt is not fastened
Market area dependant

If the driver seat belt is not fastened after 60 seconds or
if the vehicle reaches 25 km/h a warning sound will be
heard for 30 seconds, after which the warning sound
will go ON and OFF and the warning symbol will
continue to show until the seat belt is fastened.
The warning messages are always available, press the
READ button to view stored messages.
Seat Belt Fastening
When parked on an incline, the seat belt may lock
as it is withdrawn. This is not a fault. If the mechanism
locks, release the belt tension and then pull the belt
very gently to avoid operation of the inertia lock.
