• If vehicle height is not within ± 10 mm (0.39 in) of the specification, perform the control unit initialization
procedure. Refer to SCS-7, "
CONSULT-III Function" .
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
• This type of alignment is re commended for any NISSAN vehicle.
• The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
• The alignment machine itself should be ca pable of accepting any NISSAN vehicle.
• The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated. • Your alignment machine should be regularly calibrated in order to give correct information.
• Check with the manufacturer of your specific a lignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-28, "Wheel
Alignment" .
1. When displaying the alignment settings, many alignm ent machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
• The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.
• This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
• Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the vehicle and rotate the wheels 1/2 turn both ways.
• See Instructions in the alignment machine you are using for more information.
CAMBER
1. Measure camber of both the right and left wheels with a suitable alignment gauge and adjust as necessary to specification.
2. If outside of the specified value, adjust the camber using the adjusting bolt in the front lower link.
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 0 ° 5' with each graduation of the adjust-
ing bolt.
3. Tighten the adjusting bolt nuts to specification.
TOE-IN
1. Bounce the rear of the vehicle up and down two to three times to stabilize the vehicle height. Refer to RSU-29, "
Wheelarch Height (Unladen*1)" .
2. Push the vehicle straight ahead about 5 m (16 ft). Camber : Refer to
RSU-28, "
Wheel Alignment" .

3. Install balance weight in the position shown. CAUTION:
• Do not install the inner bala nce weight before installing
the outer balance weight.
• Before installing the balance weight, be sure to clean the mating surface of the road wheel.
• When installing balance weight (1) to road wheel, set it into the grooved area (A) on the inner wall of the road wheel as shown
so that the balance weight cent er (B) is aligned with the bal-
ancer machine indication position (angle) (C).
CAUTION:
• Always use genuine NISSAN adhesive balance weights.
• Balance weights are non-re usable; always replace with
new ones.
• Do not install more than th ree sheets of balance weight.
4. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown.
CAUTION:
Do not install one balance weight sheet on top another.
5. Start balancer machine again.
6. Install balance weight on inner side of road wheel in the bal- ancer machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
7. Start balancer machine. Make sure that inner and outer residual imbalance values are 5 g (0.17 oz) each or below.
8. If either residual imbalance value exceeds 5 g (0.17 oz), repeat installation procedures.
TIRE ROTATION
• Follow the maintenance schedule for tire rotation service intervals.
Refer to MA-6, "
General Maintenance".
• When installing the wheel, tighten wheel nuts to the specified torque.
CAUTION:
• When installing wheels, tighte n them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
• Be careful not to tighten wh eel nut at torque exceeding the
criteria for preventing strain of disc rotor.
• Use NISSAN genuine wheel nuts for aluminum wheels.

INFOID:0000000001534678
NOTE:
Follow the maintenance schedule for tire rotation service intervals. Refer to MA-29, "
Tire Rotation" .
1. Rotate the tires on each side from front to back as shown. Do not include the spare tire when rotating the tires.
CAUTION:
When installing wheel s, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
2. Adjust the tire pressure to specification. Refer to WT-51, "
Tire" .
3. After the tire rotation, retighten the wheel nuts after the vehicle has been driven for 1,000 km (600 miles), and also after every
wheel and tire have been installed such as after repairing a flat tire. Wheel nut torque : 133 N·m (14 kg-m, 98 ft-lb)
