Note:

  • When the brake pedal is first depressed after replacing the brake pads or pushing back the disc brake piston, DTC C1341, C1342, C1343 and/or C1344 may be stored. As there is no malfunction, clear the DTCs.

  • While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or any door courtesy switch is turned on. Therefore, when servicing, do not depress the brake pedal or open/close the doors while the auxiliary battery is connected.

  • Be sure to read the "PRECAUTION" thoroughly before servicing.

PROCEDURE


  1. Click here

    ADJUST STANDARD VEHICLE HEIGHT

    Tip:

    Check the vehicle condition when operating to the standard vehicle height setting.


    • Perform the work with the vehicle stopped on a flat surface.

    • Make sure the hood is closed.

    • Make sure the luggage compartment door closed

    • Set the shift lever to P.

    • Make sure the courtesy lights are not on.

    • Do not depress the brake pedal.

    • Perform height adjust from outside of the vehicle to avoid vehicle height changes due when getting out of the vehicle.


    1. Adjust the air pressure in the tires.

    2. Record the vehicle setting conditions on the multi-information display.

    3. Get out of the vehicle and bounce the vehicle up and down at the corners to stabilize the suspension.

    4. From the outside of the vehicle, select access mode and turn it off via the vehicle setting conditions on the multi-information display.

    5. Operate the height control switch from outside the vehicle and adjust the vehicle height to HIGH

    6. After vehicle height control is completed, operate the height control switch from outside the vehicle and return the vehicle height to NORMAL.

    7. After vehicle height control is completed, select vehicle height control mode and turn it off via the vehicle setting conditions on the multi-information display.

    Note:

    Inspect while the vehicle is unloaded.


    1. B004W9GC10
      *a Camber-caster-kingpin Gauge

      Install a camber-caster-kingpin gauge.

    2. w/ Air suspension:

      Inspect the camber.

      Camber (Unloaded Vehicle)
      Item Camber Inclination Right-left Difference
      for 2WD w/ Dynamic Rear Steering -1°25' +/-45' (-1.42° +/-0.75°) 0°30' (0.50°) or less
      w/o Dynamic Rear Steering -1°25' +/-45' (-1.42° +/-0.75°) 0°30' (0.50°) or less
      for AWD - -1°14' +/-45' (-1.23° +/-0.75°) 0°30' (0.50°) or less
      Tip:

      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.

    3. w/o Air suspension:

      Inspect the camber.

      Camber (Unloaded Vehicle)
      Item Camber Inclination Right-left Difference
      for 2WD w/o Dynamic Rear Steering -1°06' +/-45' (-1.10° +/-0.75°) 0°30' (0.50°) or less
      for AWD w/o Dynamic Rear Steering -0°55' +/-45' (-0.92° +/-0.75°) 0°30' (0.50°) or less
      Tip:

      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.


    1. Bounce the vehicle up and down at the corners to stabilize the suspension.

    2. Release the parking brake and move the shift lever to N.

    3. Push the vehicle straight ahead approximately 5.0 m (16.4 ft.). (Step A)

    4. B004TKBC02
      *a Tread Center Mark
      *b Dimension B
      B004SZX Front of the Vehicle

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

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

      Tip:

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

    6. B004VJDC02
      *a Dimension A
      B004SZX Front of the Vehicle

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

      Toe-in (Unloaded Vehicle)
      Specified Condition

      B - A: 3.0 +/- 2.0 mm (0.1181 +/- 0.0787 in.)
      Tip:

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

      If the toe-in is not within the specified range, adjust it at the toe control link sub-assembly.

      1.5 mm (0.0591 in.) or less

    2. Remove the steering rack boot clips.

    3. Loosen the tie rod assembly lock nuts.

    4. Adjust the steering rack ends if the difference in thread length between the right and left steering rack ends is not within the specified range.


      1. If the toe-in measurement is greater than the specified range (too much toe-in), shorten the longer steering rack end 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-out), lengthen the shorter steering rack end so that the length difference is within the specified range.

      3. Measure the toe-in.

    5. Turn the right and left steering rack ends by an equal amount to adjust the toe-in.

      Toe-in (Unloaded Vehicle)
      Specified Condition

      C + D: 0°14' +/- 0°09' (0.23° +/- 0.15°)

      B - A: 3.0 +/- 2.0 mm (0.1181 +/- 0.0787 in.)
      Tip:

      Perform adjustments so that the value is as close as possible to the median of the specified range.

    6. Make sure that the thread length of the right and left steering rack ends are the same.

    7. Tighten the tie rod assembly lock nuts.

      55 N*m 561 kgf*cm 41 ft.*lbf
      Note:

      Hold the width across flat of the tie rod end and tighten the lock nut.

    8. Place the steering rack boots on the seats and install the steering rack boot clips.

      Tip:

      • Make sure that the steering rack boots are not twisted.

      • Make sure that the steering rack boot clips are facing towards the front of the vehicle.

    9. Perform neutral position memorization and motor rotation angle sensor calibration for the dynamic rear steering system.
