Steering System Maintenance
Structure Introduction
The steering wheel has an airbag module which should only be inspected and repaired by a professional. The
steering column's upper section adopts a steel deformation and energy absorbing crumple structure which
ensures collision protection for the driver. The lower section uses a high precision sliding spline structure,
which can effectively eliminate structural interference caused by body deformation. The steering column angle
is adjustable, which can more easily adapt to the driver, and at the same time possesses reasonable reverse
efficiency to ensure the driver has a good feel for the road. Steering sys\
tem is as shown below:
Steering column assembly removal and
installation
1. Remove the airbag.
(a) Disconnect the battery's negative cable, and wait for
one minute before canceling the airbags function in
