INSPECTION

PROCEDURE

1. INSPECT TIRES

(a) Inspect the tires for wear and proper inflation pressure.

Cold Tire Inflation Pressure:

Tire Size	Cold Tire Inflation Pressure
Front	Rear
215/55R17 94V	250 kPa (2.5 kgf/cm2, 36 psi)
235/45R18 94V 235/40R19 92V	240 kPa (2.4 kgf/cm2, 35 psi)

Tire Size

Cold Tire Inflation Pressure

Front

Rear

215/55R17 94V

250 kPa (2.5 kgf/cm2, 36 psi)

235/45R18 94V

235/40R19 92V

240 kPa (2.4 kgf/cm2, 35 psi)

Cold Tire Inflation Pressure (for Compact Spare Tire):

Tire Size	Cold Tire Inflation Pressure
T155/70D17 110M	420 kPa (4.2 kgf/cm2, 60 psi)

(1) Perform initialization.

(2) Tire pressure adjustment method when warm:

Turn the engine switch (for Gasoline Model) or power switch (for HV Model) off.
Connect the Techstream to the DLC3.
Turn the engine switch (for Gasoline Model) or power switch (for HV Model) on (IG).
Turn the Techstream on.
Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
Adjust the tire pressure so that the displayed value is equal to the set pressure.
Perform initialization and check that initialization completes.
for HV Model: Click here

for Gasoline Model: Click here
Check and record the value of the Data List item "Temperature in Tire". (Ts)
Check and record the ambient temperature during tire pressure adjustment. (Tm)
Readjust the tire pressure according to the difference between the tire internal temperature (Ts) and the ambient temperature (Tm). (P)
HINT:

Tire internal temperature: Ts, Ambient temperature: Tm, Tire pressure readjustment value: P

P = (Specified Pressure) + (Ts - Tm)
Check the pressure adjustment value with the Data List item "Tire Inflation Pressure".

(b) Using a dial indicator, check the runout of the tires.

Maximum Tire Runout:

1.0 mm (0.0393 in.)

HINT:

Measure the runout with the wheel assembly removed from the vehicle.

2. ROTATE TIRES

(a) Remove the wheel assembly.

3. INSPECT AND ADJUST WHEEL BALANCE

(a) Inspect and adjust the off-the-car balance.

Maximum Wheel Imbalance:

8.0 g (0.0176 lb)

NOTICE:

Use a cleaning detergent to remove dirt, oil and water from the surface where the balance weight is to be adhered.
Do not touch the adhesive surface of the balance weight.
Adhere a stick-on type balance weight to the flat surface*a shown in the illustration.
Push the balance weight with your finger to securely adhere it to the desired position.
Do not reuse balance weights.
Use only LEXUS genuine stick-on type balance weights or equivalent.

HINT:

Use stick-on type balance weights for both the inner and outer side.
If the tires vibrate even after the off-the-car balance adjustment, adjust the wheel balance with on-the-car balancing as necessary.

*a	25 mm (0.984 in.)
