Driver and front passenger airbags are fitted to all Jazz models, while side airbags feature on the SE Sport model. Front seatbelt pre-tensioners are featured across the range. All three rear seatbelts, including that in the centre, are three-point for maximum safety, while a third centre head rest is available as an option.

To reduce the likelihood of whiplash injuries during rear impacts, a new front seat design is used. Headrests are now moved slightly further forward, while the bending characteristics of the upper seat structure provide a more controlled energy-absorbing role to effectively cushion the occupant as he or she is pushed back.


Child seat ISOFIX and tether anchor

The rear seat is equipped with two ISOFIX child seat fittings that ensure the correct installation of the child seat in a direct connection to the car body for greater safety; an ISOFIX compatible child seat can also be fitted to a car not equipped with the system.

Research has demonstrated that the effectiveness of ISOFIX depends on the shape of the child seat, how it matches the shape of the car seat and the firmness of that car seat. This is because, in the event of a frontal impact, it is still possible for a child seat to rotate forwards, potentially placing additional forces on the neck and torso of the child. That's why Honda is pioneering the fitment of child seat tethers in its new models, including Honda Jazz. The tether runs from the top of the child seat and is connected to a hook located in the roof of the load area, which is covered by a plastic cover when not in use.


Class-leading refinement

Appropriately for an innovative small car, Noise Vibration and Harshness (NVH) performance of the Jazz is to a high level and both road noise and acceleration noise place it at the very forefront of the class. The high stiffness platform plays a key role in this regard. Specific measures include sealed liquid engine and transmission mounts (see Drivetrain section) and an exhaust system utilising double spherical damping joints. The NVH characteristics of the engine are reduced at source by a number of features including the high stiffness cylinder block, the large diameter crankshaft journals for added stiffness, the light weight, high stiffness aluminium sump, and the centre feed intake manifold.

Noise intrusion into the cabin is reduced significantly by the use of double seals entirely encircling all four door apertures. These are located on both the inner edge of the door and on the outer edge to create a very efficient seal.

Through the use of high performance materials and careful analysis of their effect, Honda has achieved a highly refined cabin ambience, yet reduced the weight of insulating materials by between 30 and 50 per cent depending on location. Among the measures adopted are:

- Bonnet insulator
- Dash outer insulator
- Front wing end insulator
- Dash panel sandwiched with melt sheet
- Noise-absorbing roof lining
- Urethane foam dash insulator
- Urethane foam floor insulator
- Noise absorption floor insulator
- Floor-applied, light weight high-damping melt sheet
- Noise-eliminating urethane foam placed within the B-pillar
