EXCEPT TRACK PACK-SPECIFIC SUSPENSION : Wheel Alignment

INFOID:0000000009163956

CAUTION:

• This work is recommended to be performed by GT-R certified NISSAN dealer.
• Adjust wheel alignment with the vehicle in customer's regular use condition (e.g. normal stock

items), with the fuel in full-tank condition, and with no one in the vehicle.

• To adjust wheel alignment, set tire pressure at 250 kPa (2.5 kg/cm

2

, 36 psi). After adjusting wheel

alignment, adjust tire pressure to the specified value. Refer to 

WT-13, "Tire"

.

CAMBER, TOE-IN

Setting guide depending on the customer’s driving

• Adjust wheel alignment to the customer’s driving style.
• Never set to toe-out.
- Always adjust to toe-in. If the wheels change to toe-out, tire partial wear is accelerated and local heating may

be accelerated in the inner side of tires.

- For the above reasons, always adjust to toe-in for the vehicle of a customer who drives on a racetrack.
- Engaging in performance driving on a racetrack and ultra-high-speed driving, be sure to adjust toe-in to 2.0

mm (0.079 in) or less. If used beyond this range, it is not covered by the warranty.

• When driving on a racetrack, recommend to adjust the alignment to the “Performance driving on a racetrack”

setting. If the negative camber angle is insufficient driving on a technical course including many tight turns
may result in wear on the outside of the tire and this can cause an accident. [To avoid uneven wear, servicing
the vehicle after performance driving (at the customer's expense) is recommended to result the alignment to
the original setting.]

• Wheel alignment can be changed in process of time and mileage, as suspension parts do not adjust to each

other up to the mileage of about 1,000 miles or 2,000 km.

• Remarks for up to the mileage of 1,000 miles or 2,000 km
- Toe angle of one-side wheel: See reference value.

TRACK PACK-SPECIFIC SUSPENSION : Wheel Alignment

INFOID:0000000009163957

CAUTION:

• This work is recommended to be performed by GT-R certified NISSAN dealer.
• Adjust wheel alignment with the vehicle in customer's regular use condition (e.g. normal stock

items), with the fuel in full-tank condition, and with no one in the vehicle.

• To adjust wheel alignment, set tire pressure at 250 kPa (2.5 bar, 2.5 bar, 2.5 kg/cm

, 36 psi). After

adjusting wheel alignment, adjust tire pressure to the specified value. Refer to

• Adjust wheel alignment to the customer’s driving style.
• Never set to toe-out.
- Always adjust to toe-in. If the wheels change to toe-out, tire partial wear is accelerated and local heating may

be accelerated in the inner side of tires.

- For the above reasons, always adjust to toe-in for the vehicle of a customer who drives on a racetrack.
- Engaging in performance driving on a racetrack and ultra-high-speed driving, be sure to adjust toe-in to 2.0

mm (0.079 in) or less. If used beyond this range, it is not covered by the warranty.

• Insufficient negative camber during hard cornering on a racetrack may result in tire wear. Therefore, recom-

mend the customer to adjust negative camber angle in the negative direction when driving on a racetrack.
[To avoid uneven wear, recommend the customer to have the camber angle aligned in the positive direction
at an inspection after performance driving (at customer's expense).]

• Wheel alignment can be changed in process of time and mileage, as suspension parts do not adjust to each

other up to the mileage of about 1,000 miles or 2,000 km.

• Remarks for up to the mileage of 1,000 miles or 2,000 km
- Toe angle of one-side wheel: See reference value.
• Each part of the suspension may not conform during a normal driving because of the adoption of a hard rate

coil spring and a high damping shock absorber.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000009160068

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precautions Necessary for Steering Wheel Rotation After Battery Disconnection

INFOID:0000000009160069

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition switch to the LOCK position,

then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect

both battery cables.

• Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing

work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.

OPERATION PROCEDURE

1.

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

2.

Turn the ignition switch to ACC position.
(At this time, the steering lock will be released.)

3.

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
