CAUTION:
 Every time the vehicle is lifted up, main tain the complete vehicle curb condition.
 Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up poi nt on the rear side garage jack with a mission
jack or equivalent.
 Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the fr ont side garage jack with a mission jack or equiv-
alent.
 Be careful not to smash or do not do an ything that would affect piping parts.
Garage Jack and Safety StandINFOID:0000000001325681
WARNING:
 Park the vehicle on a level surface when using th e jack. Make sure to avoid damaging pipes, tubes,
etc. under the vehicle.
 Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.

AWD MODELS
INFINITI recommends that a dolly be used as illustrated when towing AWD models.
CAUTION:
Never tow AWD models with any of the wheels on the ground as this may cause serious and expen-
sive damage to the powertrain.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000001325685
Securely install the vehicle recovery hook stored with jacking tools.
Make sure that the hook is properly secured in the stored place after
use.
WARNING:
 Stand clear of a stuck vehicle.
 Do not spin your tires at high speed. This could cause them to
explode and result in serious injury. Parts of your vehicle
could also overheat and be damaged.
CAUTION:
 Tow chains or cables must be attached only to the vehicle recovery hooks or main struct ural members of the vehicle.
Otherwise, the vehicle body will be damaged.
 Do not use the vehicle tie downs to free a vehicle stuck in
sand, snow, mud, etc. Never to w the vehicle using the vehicle
tie downs or recovery hooks.
 Always pull the cable straight out from the front of the vehicle.
Never pull on the hook at an angle.
 Pulling devices should be rout ed so they do not touch any
part of the suspension, steer ing, brake or cooling systems.
 Pulling devices such as ropes or canvas straps are not rec- ommended for use in vehicle towing or recovery.
AUTOMATIC TRANSMISSION
To tow a vehicle equipped with an automatic tr ansmission, an appropriate vehicle dolly MUST be placed under
the towed vehicle's drive wheels. Always follow the dolly manufacture's recommendations when using their
product.
If the vehicle is stuck in sand, snow , mud, etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control System.
2. Make sure the area in front and behind the vehicle is clear of obstructions.

PERIODIC MAINTENANCE
NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged or if the auto belt tensioner reading (only for VK45DE engine) reaches the maximum limit.
(2) Maintenance-free item. For service procedures, refer to FL section.
(3) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(4) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perfo rm
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required
CHASSIS AND BODY MAINTENANCE
Abbreviations: R = Replace. I = Inspec t. Correct or replace if necessary.
NOTE:
(1) Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and
automatic transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new
vehicle limited warranty.
(2) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.

On-Vehicle Inspection and ServiceINFOID:0000000001327712
CHECKING CONDITION OF INSTALLATION
 Check installation condition of steering gear assemb ly, front suspension, axle and steering column.
 Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
 Check if the mounting bolts for steering gear assembly are loose or not. Refer to PS-17
.
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumfe rence when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-5,
"Wheel Alignment Inspection".
1. Set vehicle to the straight direction, chec k if steering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock
nuts of steering outer sockets, then adjust outer so cket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating te mperature. [Make sure temperature of fluid is
approximately 50 to 80 °C (122 to 176 °F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-27, "
On-Vehicle Inspection and Service".
End play of the axle direction for steering wheel : 0 mm (0 in)

STEERING WHEEL
a. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to PS-12, "Removal and
Installation", FA X - 4 , "Removal and Installation", FAX-11, "Removal and Installation".
b. Start and run engine at idle to make sure steer ing fluid has reached normal operating temperature.
c. While pulling outer socket slowly in ±11.5 mm ( ±0.453 in) range
from neutral position, make sure rack sliding force is within
specification.
d. If rack sliding force is not within specification, overhaul steering gear assembly.
CHECKING FRONT WHEEL TURNING ANGLE
 Check front wheel turning angle after the toe-in inspection. Placefront wheels on turning radius gauges and rear wheels on stands
so that vehicle can be level. Check the maximum inner and outer
wheel turning angles for LH and RH road wheels.
 Start engine and run at idle, turn steering wheel all the way right and left, measure the turning angle.
 Measure rack stroke if angles are outside the specified value.
 Disassemble steering gear assembly to check the cause that rack
stroke is outside of the standard.
 Steering angles are not adjustable. Check steering gear assembly, steering column assembly and front suspension components for
wear or damage if any of the turning angles are different from the
specified value. Replace any of them, if any non-standard condi-
tion exists.
Removal and InstallationINFOID:0000000001327713
REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation. Rack sliding force
