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.

Tech Tips

Use the same procedure for the RH and LH side.
The following procedure is for the LH side.

PROCEDURE

ADJUST STANDARD VEHICLE HEIGHT
Tech Tips

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.

MEASURE VEHICLE HEIGHT

Note

Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
Be sure to perform measurement on a level surface.
If it is necessary to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.
Inspect while the vehicle is unloaded.
The standard value shown here is a value that is used for performing a wheel alignment and does not indicate the height of an actual vehicle.

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

Measure the vehicle height.

Measurement Points:

A: Ground clearance of front wheel center

B: Ground clearance of front center position of front No. 2 suspension lower arm assembly front bush installation bolt

C: Ground clearance of rear wheel center

D: Ground clearance of pin hole center of the rear suspension arm attachment sub-assembly

Vehicle Height (Unloaded Vehicle)

Item	Front A - B	Rear C - D
w/ Air suspension	132.0 mm (5.20 in.)	88.0 mm (3.46 in.)
w/o Air suspension	116 mm (4.57 in.)	71 mm (2.80 in.)

INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

Note

Inspect while the vehicle is unloaded.

*a Turning Radius Gauge

*b Camber-caster-kingpin Gauge

Install a camber-caster-kingpin gauge and place the front wheels on the center of a turning radius gauge.

Inspect the camber, caster and steering axis inclination.

Camber (Unloaded Vehicle)

Item	Camber Inclination	Right-left Difference
w/ Air suspension	-0°36' +/-45' (-0.60° +/-0.75°)	0°30' (0.50°) or less
w/o Air suspension	-0°16' +/-45' (-0.27° +/-0.75°)	0°30' (0.50°) or less

Caster (Unloaded Vehicle)

Item	Caster Inclination	Right-left Difference
w/ Air suspension	7°25' +/- 0°45' (7.42° +/-0.75°)	0°45' (0.75°) or less
w/o Air suspension	6°52' +/-45' (6.87° +/-0.75°)	0°45' (0.75°) or less

Steering Axis Inclination (Unloaded Vehicle)

Item	Steering Axis Inclination Reference
w/ Air suspension	8°07' (8.12°)
w/o Air suspension	8°15' (8.25°)

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 C)

*a	Tread Center Mark
*b	Dimension B
	Front of the Vehicle

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

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

Tech Tips

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

*a	Dimension A
	Front of the Vehicle

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

Toe-in (Unloaded Vehicle)

Specified Condition
C + D: 0°00' +/- 0°09' (0.00° +/-0.15°)
B - A: 0.0 +/- 2.0 mm (0 +/- 0.0787 in.)

Tech Tips

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

If the toe-in is not within the specified range, adjust it at the steering rack ends.

ADJUST TOE-IN

*1 Steering Rack Boot Clip

*2 Lock Nut

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

Standard Difference

1.5 mm (0.0591 in.) or less
Remove the steering rack boot clips.
Loosen the tie rod assembly lock nuts.
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), lengthen the shorter 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), shorten the longer steering rack end so that the length difference is within the specified range.
3. Measure the toe-in.

Standard Difference
1.5 mm (0.0591 in.) or less

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°00' +/- 0°09' (0.00° +/-0.15°)
B - A: 0.0 +/- 2.0 mm (0 +/- 0.0787 in.)

Tech Tips

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

Make sure that the thread length of the right and left steering rack ends are the same.
Tighten the tie rod assembly lock nuts.

Torque:

88 N*m { 897 kgf*cm, 65 ft.*lbf }
Place the steering rack boots on the seats and install the steering rack boot clips.
Tech Tips
- 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.

INSPECT WHEEL ANGLE

*a	Inside
*b	Outside
	Front of the Vehicle

Put tread center marks on the rearmost points of a turning radius gauge.

Turn the steering wheel fully to the left and right and measure the turning angle.

Note

Inspect while the vehicle is unloaded.

If the right and left inside wheel angles differ from the specified value, check and adjust the right and left steering rack end lengths.
