Note:

The rear wheel suspension is equipped with trapezoidal levers. The suspension beam is made of steel, the trapezoidal arms are made of a hollow aluminum profile. This design is characterized by low weight and compactness. This makes it possible to achieve both the front-wheel drive version and the all-wheel drive version with a low boot floor and an optimal width of the load compartment.

All lever elements through rubber-metal supports are hinged to an elastically mounted suspension beam, which ensures effective damping of body vibrations. Suspension of the rear suspension is carried out by coil springs and two shock absorbers, which are located separately and can be easily removed.

Welding and straightening work on the bearing and guiding elements of the front suspension is not allowed. Self-locking nuts, as well as rusty bolts/nuts, must be replaced during repairs.
