RECOMMENDED FLUIDS AND LUBRICANTS
Revision: 2006 January2006 M35/M45
RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and Lubricants NLS0007E
*1: For further details, see “SAE Viscosity Number”.
*2: 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.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0
C (32F).
*4: DEXRONTM III/ MERCONTM or equivalent may also be used. Outside the continental United States and Alaska contact an INFINITI
dealer for more information regarding suitable fluids, including recommended brand(s) of DEXRON TM III/ MERCONTM automatic trans-
mission fluid.
*5: For Canada, NISSAN Automatic Transmission Fluid (ATF), DEXRON
TM III/ MERCONTM , or equivalent ATF may also be used.
*6: Available in mainland U.S.A. through your INFINITI dealer.Capacity (Approximate)

Balancing Wheels (Bonding Weight Type)NLS00087
REMOVAL
1. Remove inner and outer balance weights from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
2. Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT
If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
Do not install the inner balance weight before installing the outer balance weight. Oil grade and Viscosity:
Refer to MA-12, "
