Adjustment [08/2013 - ]

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

If a wheel alignment has been performed, or if suspension or underbody components have been removed/installed or replaced, be sure to perform the following initialization procedure in order for the system to function normally:

Perform zero point calibration of the yaw rate and acceleration sensor.

INSPECT TIRES . Refer to INSPECTION [08/2013 - ] - Step 1
MEASURE VEHICLE HEIGHT See step 2

INSPECT CAMBER

NOTE:

Inspect while the vehicle is unloaded.

Install a camber-caster-kingpin gauge.

Inspect the camber.

Camber (Unloaded Vehicle)

Camber Inclination	Right-left Difference
-1°10' +/- 0°45' (-1.17° +/- 0.75°)	0°45' (0.75°) or less

HINT:

Camber is not adjustable. If the measurement is not within the specified range, inspect the suspension parts for damage and/or wear, and replace them if necessary.

INSPECT TOE-IN

NOTE:

Inspect while the vehicle is unloaded.

Bounce the vehicle up and down at the corners to stabilize the suspension.
Release the parking brake and move the shift lever to N.
Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step A)

Put tread center marks on the rearmost points of the rear wheels and measure the distance between the marks (dimension B).

Slowly push the vehicle straight ahead to cause the rear wheels to rotate 180°. Use the rear tire valve as a reference point.
HINT:

Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from Step A again.

Measure the distance between the tread center marks on the front of the rear wheels (dimension A).

Toe-in (Unloaded Vehicle)

Specified Condition
C + D: 0°13' +/- 0°10' (0.22° +/- 0.17°)
B - A: 2.5 +/- 2.0 mm (0.0984 +/- 0.0787 in.)

HINT:

Measure "B - A" only when "C + D" cannot be measured.

If the toe-in is not within the specified range, adjust it at the rear No. 2 suspension arms.

ADJUST TOE-IN
1. Measure the lengths of the right and left rear No. 2 suspension arms.

  Standard difference
  
  1.5 mm (0.0591 in.) or less
2. Loosen the 2 lock nuts.

3. If the length difference between the left and right rear No. 2 suspension arm assemblies is not within the specified range, adjust it by following the procedures below.
  1. If the toe-in measurement is greater than the specified range (too much toe-out), extend the shorter rear No. 2 suspension arm by rotating the adjusting tube so that the length difference is within the specified range.
  2. If the toe-in measurement is less than the specified range (too much toe-in), shorten the longer rear No. 2 suspension arm by rotating the adjusting tube so that the length difference is within the specified range.
  3. Measure the toe-in.
4. Turn the right and left adjusting tubes by an equal amount to adjust toe-in.
  HINT:
  - Try to adjust the toe-in to the center of the specified range.
  - One turn of each adjusting tube will adjust the toe-in by approximately 11.3 mm (0.445 in.).
5. Tighten the lock nuts while securing the adjusting tube in the order indicated below:
  1. Tighten the outside lock nut.
  2. Tighten the inside lock nut.
  3. Retighten the outside lock nut.
