2. Before installing the tire pressure sensor, clean the mating surfaces on the sensor and the wheel.  

3. Install the tire pressure sensor (A) to the wheel (B), and tighten the valve nut (C) finger tight. Make 

sure the pressure sensor is resting on the wheel.

4. Tighten the valve nut to the specified torque while holding the tire pressure sensor toward (D) the 

wheel. You may hear a snap or pop as you tighten the nut. This is normal. 

5. Lube the tire bead, and position the wheel so the tire machine (A) and tire iron (B) are next to the 

NOTE:



Do not reuse the nuts that had been tightened, even one time, to 
the specified torque, as they are deformed inside (E).  



Do not use air or electric impact tools to tighten a valve stem nut.  



Tightening the nut beyond the specified torque can damage the 
nut.  



Make sure that there is no space between the sensor and the 
wheel.

6. Inflate the tire to 300 kPa (3.1 kgf/cm

2

 , 44 psi) to seat the tire bead to the rim, then adjust the tire 

pressure to front 220 kPa (2.2 kgf/cm

2

 ,32 psi), rear 210 kPa (2.1 kgf/cm

2

 ,30 psi), and install the 

valve stem cap. 

7. Check and adjust the wheel balance, then install the wheels to the vehicle.  

8. Remove the safety stands, and lower the vehicle.  

9. Connect the HDS, and memorize the pressure sensor ID(s) (see MEMORIZING THE TIRE 

PRESSURE SENSOR ID ).  

RESETTING THE PAX SYSTEM WARNING 

When a tire goes flat or is very low on pressure, the multi-information display will show "PAX SYSTEM 
WARNING, RUN FLAT DRIVING." After the tire is repaired or replaced, you must reset the warning 
indicator (and the mileage counter that supports it), no matter how far the vehicle was driven in the run flat 
mode. 

1. Put the gauge control module into the self-diagnostic mode: 



Turn the headlight switch to ON.  



Press and hold the SELECT/RESET (SELECT/RESET Information switch).  



Turn the ignition switch to ON (II).  



Within 5 seconds, turn the headlights to AUTO, then to ON, and then to AUTO again.  



Within 5 seconds, release the SELECT/RESET switch, then push and release the switch three 
times.  

2. Once the gauge control module is in the self-diagnostic mode, press and hold the INFO button on the 

steering wheel for 5 seconds to get to the CUSTOMIZE MENU.  

3. With the INFO button, scroll through to the PAX RESET screen, then press the SEL/RESET button 

on the steering wheel. 

NOTE:

Make sure the tire bead is seated on both sides of the rim uniformly.

4. With the INFO button, scroll through to the appropriate wheel, then press the SEL/RESET button on 

the steering wheel to reset the system warning. The screen should display PAX RESET 
"COMPLETED".  

5. Use the INFO button to scroll through to EXIT, then press the SEL/RESET button.  

6. Turn the ignition switch OFF to exit the self-diagnostic mode.
