MacPherson struts are attached to the lower wishbones via ball joints. The steering knuckles house the wheel bearings, brake calipers, and hub. A front anti-roll bar is fitted to all models. The bar is mounted via rubber bushings to the lower frame and is connected directly to the front suspension struts.

Independent rear suspension - multi-link. The rear hubs are connected to the lower frame by upper and lower arms and a guide arm.

The anti-roll bar is fixed to the lower frame and connected to the hubs by links.

The steering column has a universal joint located on the bottom side, which connects the steering shaft to the intermediate shaft, which has a second universal joint at the bottom. The lower universal joint connects the steering column to the steering gear by means of a clamp bolt.

The steering gear is mounted on the front lower frame and is connected to two steering rods by ball joints at the outer ends of the steering rods. The ends of the steering rods are threaded for adjusting the toe-in of the front wheels.

The hydraulic power steering system has a pump that is driven by the crankshaft pulley.
