Airbag Deployment
Warning: The use of accessory seat covers may prevent
the deployment of the seat side airbags and increase the risk
of injury in an accident. Do not use accessory seat covers.
Warning: All passengers, including the driver, should
always wear seat belts, whether or not an airbag is provided,
to decrease the risk of injury or death in the event of a crash.
Warning: No objects whatsoever should be attached to,
or placed on, the centre cover of the steering wheel or the
front passenger fascia panel. Such objects could cause harm
if the vehicle is in a collision severe enough to cause the
airbags to deploy.
The airbag system is not designed to protect against rear
impacts.
