6. Operation and maintenance
Tread wear indicator
The mark ① is used to indicate the wear
condition of the tire outer circle pattern. If the
tire outer circle pattern wears to the condition
as shown, the tire can no longer be used safely
and must be replaced immediately.
The height of tread wear indicator
② is 1.6
mm. If the tread pattern is worn to the indicator
surface, this tire can no longer be used safely
and must be replaced immediately.
Wheel balance
The wheels of the new vehicle are already
balanced. Due to various reasons, the wheels
may go unbalanced during operation, which
can be manifested by the vibration of the
steering mechanism.
Because unbalanced wheels can cause
excessive wear on the steering system, wheel
suspension mechanism and tires, the wheels
shall be rebalanced.
In addition, wheels must be rebalanced after
installation of a new tire or tire repair for any
wheel.
Wheel misalignment
Wheel misalignment will cause uneven and
excessive wear of the tires, affecting driving
safety. If uneven and excessive wear of the
tires is found, please go to the GAC Motor
authorized shop to check the wheel alignment
as soon as possible.
6.8 Tire chain
In winter, driving in harsh environments such
as snowy or icy roads can increase the degree
of tire wear or cause other failures. To reduce
failures in winter, the following opinions must
be followed:
-
When driving in deep snow, it is necessary
to install tire chains on the tires. In this
case, be sure to choose an equivalent
product whose size and type meet the
specifications of the tires on the vehicle.
Failure to observe this point will adversely
affect the performance and safety of the
vehicle. Moreover, operations such as
full-load driving, speeding, emergency
acceleration, emergency braking, and
emergency turning are potentially
dangerous.
- During deceleration, make full use of
the engine braking function. Emergency
braking on snowy or icy roads will cause
the vehicle to drift and slip. Keep a proper
safe distance from the lead vehicle, and
step on the brake pedal slightly. Note
that the tire chain installed on the tire
can provide a certain friction force, but it
cannot prevent sideslip.
