When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION. Use only Genuine NISSAN Matic S ATF.
Do not mix with other fluids.
. Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will
cause deterioration in driveability and
automatic transmission durability, and
may damage the automatic transmis-
sion, which is not covered by the INFINITI
new vehicle limited warranty. GUID-D565E040-B16F-4851-A817-C2480F2A6602

Check the fluid level in the reservoir.
The fluid level should be checked using the
HOT range (
* 1
: HOT MAX.,
* 2
: HOT MIN.)
at fluid temperatures of 122 to 176 8 F (50
to 80 8 C) or using the COLD range (
* 3
:
COLD MAX.,
* 4
: COLD MIN.) at fluid
temperatures of 32 to 86 8 F (0 to 30 8 C).
If the fluid is below the MIN line, add
Genuine NISSAN PSF or equivalent. Re-
move the cap and fill through the opening. CAUTION . Do not overfill.

CAUTION. Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
. Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator. GUID-2598C543-2A3B-4E05-90F6-3739930B5F0C

[ Edit: 2012/ 1/ 17 Model: V36-D ]MEASUREMENT OF WEIGHTS GUID-50D1912A-C00F-4ED3-8ACC-D24A0397214B
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is
loaded, drive to a scale and weigh
the front and the rear wheels sepa-
rately to determine axle loads. In-
dividual axle loads should not
exceed either of the gross axle
weight ratings (GAWR). The total of
the axle loads should not exceed the
gross vehicle weight rating (GVWR).
These ratings are given on the
vehicle certification label. If weight
ratings are exceeded, move or re-
move items to bring all weights
below the ratings. GUID-BC9945CE-0C0A-468B-8072-EAC4EDA8B7B5
Your vehicle was designed to be used to
carry passengers and cargo. INFINITI does
not recommend trailer towing, because it
places additional loads on your vehicle ’ s
engine, drivetrain, steering, braking, and
other systems.
An INFINITI Towing Guide (U.S. only) is
available on the website at
www.InfinitiUSA.com. This guide includes
information on trailer towing capability and
the special equipment required for proper
towing.
CAUTION Vehicle damage resulting from towing a
trailer is not covered by INFINITI warranties.
FLAT TOWING GUID-A4A9B27A-245D-4579-9712-944464AA5082
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when
towing a vehicle behind a recreational
vehicle, such as a motor home. CAUTION . Failure to follow these guidelines can
result in severe transmission damage.
. Whenever flat towing your vehicle, al-
ways tow forward, never backward.
. DO NOT tow any automatic transmission
vehicle with all four wheels on the
ground (flat towing). Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
. DO NOT tow an All-Wheel Drive (AWD)
vehicle with any of the wheels on the
ground. Doing so may cause serious and
expensive damage to the powertrain.
. For emergency towing procedures refer
to “ Towing recommended by INFINITI ”
(P.6-12) of this manual.
