Tire Rotation
Description
Front and rear tires operate at different loads and perform different steering, driving and braking functions. For
these reasons, different wear rate is formed, causing irregular wear patterns. These effects can be reduced by
rotating the tires at regular time.
Advantages of tire rotation:
Improving tread life
Maintaining traction levels
Maintaining smooth and quiet driveability
Rotation Method
Perform tire rotation as shown in the illustration.
CAUTION
Chery recommends you rotate your tires every 10000 km. However, the best suitable time for tire rotation
differs depending on driver's driving habits and road conditions.

GENERAL INFORMATION
Description
The brake control system equipped on this vehicle is ABS (Anti-lock Brake System) + EBD (Electronic Brake
Force Distribution). It mainly consists of the following components:
ABS control module assembly (hydraulic control module and electronic control module)
Wheel speed sensors (each wheel has one sensor)
The primary purpose of ABS is to prevent wheels from being locked during sudden braking. It has the
following effects:
1. Improve vehicle driving stability.
2. Improve vehicle steering ability.
3. Maintain optimal brake pressure.

2 - Rear Right Wheel Speed Sensor
3 - Rear Left Wheel Speed Sensor
4 - Front Left Wheel Speed Sensor
5 - Front Right Wheel Speed Sensor

Operation
ABS Braking
1. If ABS system detects that the wheels may be locked when applying brake, the brake system will enter
ABS braking mode. During braking, ABS control module outputs signal from each wheel speed sensor to
each solenoid valve after analysis in order to adjust the fluid pressure in each line, to prevent the wheels
from being locked.
2. There are some operating symptoms of ABS that seem to be abnormal at first, but in fact they are normal.
The symptoms are as follows:
a. If the electronic control module is malfunctioning, fail-safe function will be activated, ABS system will
not operate and ABS warning light will come on.
b. After vehicle is power on or engine is started, short "buzz" sound can be heard, which is the ABS
self-check sound, and this is normal.
c. Noise caused by the corresponding solenoid valve movement when EBD is involved in braking can be
heard, but this is normal.
d. Brake pedal may vibrate slightly and mechanical noise can be heard during ABS operation, but this is
normal.
e. Braking distance may be longer than that of vehicles without ABS when braking on rough, sandy, or
snow-covered roads.
