1. If a message appears on the multifunction display "CHECK TIRE PRESSURE" and the low tire pressure indicator, this indicates a drop in pressure or a puncture in one of the tires. In this case, it is necessary, avoiding sudden braking, to stop and bring the tire pressure to normal or replace the punctured wheel.
Note:
- Driving with low tire pressure can result in tire failure, increased fuel consumption and poor handling.
- If a tire is punctured, do not use sealant to repair the tire as it may damage the pressure sensor.
- The tire pressure monitoring system does not replace the driver, so check the condition and pressure of your tires regularly.
- The recommended tire pressure values according to tire size are indicated on the plate located on the driver's door pillar.
- The low tire pressure indicator may not come on when the tire is flat or may come on when the tire pressure is normal under the following conditions:
- If the car is in a strong electromagnetic field.
- If the radio receiver operates at a frequency close to the frequency of the pressure sensor signals.
- If the car is heavily snowed in, either the wheels are in deep snow, or the tire valve is covered with ice or snow.
- If the installed tires are not equipped with pressure sensors.
- If the vehicle is equipped with studded tires, tires with anti-skid chains.
- If the pressure sensor battery is discharged.
- If you use a spare tire.
2. Each pressure sensor has its own unique identification code. Each time the wheels are rotated or the pressure sensors are replaced, the sensors must be programmed in accordance with the position of the wheels. The sensors are programmed in the following order: front left wheel, front right wheel, rear right wheel, rear left wheel.
Note: programming all sensors should take no more than five minutes (of which the first minute is for programming the first sensor). Otherwise, the sensor programming procedure will have to be started from the beginning.
3. The procedure for programming sensors is performed as follows:
a) Apply the parking brake.
b) Turn the ignition key to the "ON" position (engine off).
c) Turn the headlight switch from the "OFF" position to the "ON" position four times within three seconds. The horn should then sound twice and the low tire pressure indicator should start flashing, indicating that the tire pressure sensors have started to install.
Note: The low tire pressure indicator will continue to flash until the sensor programming process is complete.
d) Start the programming operation of the pressure sensor for the front left wheel.
- Remove the cap from the tire valve.
- Activate the pressure sensor by increasing or decreasing the tire pressure for ten seconds (after 10 seconds, a sound signal should be heard). An audible signal will sound for 15 seconds indicating that the pressure sensor programming procedure has been completed successfully and the sensor identification code has been assigned to the given tire and wheel position.
Note:
- If the sound signal does not sound within 15 seconds, the pressure sensor programming procedure was performed incorrectly and must be started over (from step "a").
- The outer part of the tire valve cap can be used to release pressure.
d) Perform the programming operation for the pressure sensor for the front right wheel as described in paragraph "d".
e) Perform the programming operation for the pressure sensor for the rear right wheel as described in paragraph "d".
g) Perform the programming operation for the pressure sensor for the rear left wheel as described in paragraph "d".
c) After completing the programming operation of the pressure sensor for the rear left wheel (after the buzzer stops sounding) check that the low tire pressure indicator continues to flash. If the indicator continues to flash, turn the ignition off (LOCK position).
i) Inflate the tires to the correct pressure.
c) Install the caps on the wheel nipples.
4. If the message appears on the multifunction display "SERVICE TIRE MONITOR", this indicates a fault in the system. In this case, contact your dealer.
