In the case of malfunction of the ABS when excessive braking wheel may lock up. A car loses control
and can get into the skid.
In this situation, you can continue to travel, driving a car with caution.
For troubleshooting, visit the service station.
Alarm monitoring system pressure drop and the current tire
pressure
Red light sensors shows a pressure drop in the bus, a yellow light - a malfunction in the system. To
fix the problem ask for help at service stations.
Monitoring system tire failure (DDS - Deflation Detection System)
The monitoring system tire failure while driving continuously monitors the rotational speed of the
wheels. When a pressure drop in one of the tires decreases the diameter of the wheel and it rotates
faster than the other wheels. When the system detects a difference between speed, alarm light glows
red.
In this case, stop immediately and check the tire pressure. If necessary, install the spare wheel.
System functions after ignition and detects a pressure drop, starting with a speed of about 30 km / h.
NOTE
The triple flashing signaling points to initialize the system.
The monitoring system tire failure does not replace the manual control with the help of
attorney manometer.
Check the tire pressure on cold tires at least once in 14 days and before every long trip.
System Initialization
After adjusting tire pressure, and after replacing the tire or wheel system must be initialized. To do
this, with the ignition, hold DDS for approximately 4 s, alarm will flash 3 times. After a certain path
towards the system will be ready to work.
The system can be initialized only if all the tires installed the prescribed air pressure.
