9. Steering


Design and technical characteristics

Steering with the " mechanism the screw nut on the circulating balls" (a ball nut). The steering column safety (power absorbing) consists of two parts. On separate models the hydraulic booster of steering is installed.

Power steering pump

The pump of the hydraulic booster with the built-in tank is given to rotation by a mnogoruchyevy belt of the drive of auxiliary units.

Oil for hydraulic system of steering

Oil level in a tank has to concern a tag "full" or be about 20 mm from edge of a tank. Replacement of oil is not provided.
