INSPECT TIRES
Check the tires for wear and proper inflation pressure.

Tire pressure adjustment method when warm:
Note
for ECE-R64 Type:
If the tire pressure is decreased approximately 20 kPa (0.2 kgf/cm2, 2.9 psi) or more in order to adjust the tire pressure, even if the adjusted tire pressure is 80% or more than the tire pressure set during system initialization, the tire pressure warning light may illuminate if the tire pressure drops below 80% of the tire pressure set when the tires are warmed. In this case, perform initialization again.
Turn the engine switch off.
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS 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 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)
Tech Tips
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".
Using a dial indicator, check the runout of the tires.
| Maximum Tire Runout |
|---|
| 1.4 mm (0.0551 in.) |
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 adjusting the 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 lower No. 2 suspension arm bushing set bolt center
C: Ground clearance of rear wheel center
D: Ground clearance of outer strut rod set bolt center
| Vehicle Height (Unloaded Vehicle) | ||||
|---|---|---|---|---|

INSPECT CAMBER
Note
Inspect while the vehicle is unloaded.
| *a | Camber-caster-kingpin Gauge |
Install a camber-caster-kingpin gauge.
Inspect the camber.
| Camber (Unloaded Vehicle) | ||||
|---|---|---|---|---|
|
Tech Tips
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)
| *a | Tread Center Mark |
| *b | Dimension B |
|
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).
Slowly push the vehicle straight ahead to cause the rear wheels to rotate 180°. Use the rear 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 A again.
| *a | Dimension A |
|
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) | |||
|---|---|---|---|
|
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 rear No. 2 suspension arms.
ADJUST TOE-IN
Measure the lengths of the right and left rear No. 2 suspension arms.
| Standard Difference |
|---|
| 1.5 mm (0.0591 in.) or less |
Loosen the 2 lock nuts.
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.
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.
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.
Measure the toe-in.
Turn the right and left adjusting tubes by an equal amount to adjust toe-in.

Front of the Vehicle |
Tech Tips
Perform adjustments so that the value is as close as possible to the median of the specified range.
One turn of each adjusting tube will adjust the toe-in by approximately 11.3 mm (0.445 in.).
Tighten the lock nuts while securing the adjusting tube in the order indicated below:
Tighten the outside lock nut.
Tighten the inside lock nut.
Retighten the outside lock nut.
