Genuine NISSAN Matic S ATF
 INFINITI recommends using Genuine NISSAN Ma-
tic S ATF ONLY in INFINITI automatic transmis-
sions. Do not mix with other fluids. Using fluids that
are not equivalent to Genuine NISSAN Matic S ATF
may damage the automatic transmission. Damage
caused by the use of fluids other than as recom-
mended is not covered under the INFINITI’s new
vehicle limited warranty.

 INFINITI recommends using Genuine NISSAN Ma-
tic J ATF ONLY in INFINITI transfers. Do not mix
with other fluids. Using fluids that are not equiva-
lent to Genuine NISSAN Matic J ATF may damage
the transfer. Damage caused by the use of fluids
other than as recommended is not covered under
the INFINITI’s new vehicle limited warranty.
CAPACITIES AND RECOMMENDED
FLUIDS/LUBRICANTS

10-18Technical and consumer information
Do not tow a trailer with your
vehicle.
FLAT TOWING
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,
always tow forward, never back-
ward.
. DO NOT tow any Automatic Trans-
mission (AT) 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 any 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.6-10).
Automatic Transmission (AT)
All-Wheel Drive (AWD) models:
Do not tow an AWD vehicle with any of the
wheels on the ground.
Two-Wheel Drive (2WD) models:
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly
MUST
be placed under the towed vehicle’s
drive wheels. Alwaysfollow the dolly man-
ufacturer’s recommendations when using
their product. DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where applic-
able on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road character-
istics and climate.
TOWING A TRAILERUNIFORM TIRE QUALITY GRADING

WARNING
A vehicle equipped with Intelligent All-
Wheel Drive (AWD) should never be
tested using a two wheel dynamometer
(such as the dynamometers used by
some states for emissions testing), or
similar equipment. Make sure you inform
test facility personnel that your vehicle
is equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in transmission
damage or unexpected vehicle move-
ment which could result in serious vehicle
damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be in
what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the
emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition” can
be obtained by ordinary usage of the vehicle.
If a powertrain system component is re-
paired or the 12-volt battery is discon-
nected, the vehicle may be reset to a “not
ready condition”. Before taking the I/M test,
check the vehicle’s inspection/maintenance test readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condi-
tion is “ready”.
It is recommended you visit an INFINITI
retailer to set the “ready condition” or to
prepare the vehicle for testing.
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a
vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
.
How various systems in your vehicle were
operating;
. Whether or not the driver and passenger
safety belts were buckled/fastened;
. How far (if at all) the driver was depres-
sing the accelerator and/or brake pedal;
and,
. How fast the vehicle was traveling.
. Sounds are not recorded.
These data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.
NOTE: EDR data are recorded by your
vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR
under normal driving conditions and no
personal data (e.g. name, gender, age and
crash location) are recorded. However, other
parties, such as law enforcement, could
combine the EDR data with the type of
