NOTE:
(1) After 40,000 miles (64,000 km) or 48
months, inspect every 10,000 miles
(16,000 km) or 12 months. Replace the
drive belt if found damaged.
(2) If operating mainly in dusty conditions,
more frequent maintenance may be re-
quired.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000
miles (168,000 km) or 84 months. After first replacement, replace every 75,000
miles (120,000 km) or 60 months.
(5) Use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. Mixing any other type of coolant or
the use of non-distilled water may reduce
the life expectancy of the factory fill cool-
ant.
(6) Replace spark plug when the plug gap
exceeds 0.053 in (1.35 mm) even if withinspecified replacement mileage.
(7) Periodic maintenance is not required.
However, if valve noise increases, inspect
valve clearance.
*: Maintenance items and intervals with “*”
are recommended by INFINITI for reliable
vehicle operation. The owner need not to
perform such maintenance in order to
maintain the emission warranty or manu-
facturer recall liability. Other maintenance
items and intervals are required.

10-14Technical and consumer information
WARNING
.It is extremely dangerous to
ride in a cargo area inside the
vehicle. In a collision, people
riding in these areas are more
likely to be seriously injured or
killed.
.Do not allow people to ride in
any area of vehicle that is not
equipped with seats and seat
belts.
.Be sure everyone in your vehicle
is in a seat and using a seat belt
properly.
TERMS
It is important to familiarize yourself
with the following terms before load-
ing your vehicle:
.Curb Weight (actual weight of
your vehicle) - vehicle weight in-
cluding: standard and optional
equipment, fluids, emergency
tools, and spare tire assembly. This
weight does not include passen- gers and cargo.
. GVW (Gross Vehicle Weight) -
curb weight plus the combined
weight of passengers and cargo.
. GVWR (Gross Vehicle Weight Rat-
ing) - maximum total combined
weight of the unloaded vehicle,
passengers, luggage, hitch, trailer
tongue load and any other op-
tional equipment. This information
is located on the F.M.V.S.S./C.M.
V.S.S. label.
. GAWR (Gross Axle Weight Rating)
- maximum weight (load) limit
specified for the front or rear axle.
This information is located on the
F.M.V.S.S./C.M.V.S.S. label.
. GCWR (Gross Combined Weight
Rating) - The maximum total
weight rating of the vehicle, pas-
sengers, cargo, and trailer.
. Vehicle Capacity Weight, Load
limit, Total load capacity - max-
imum total weight limit specified
of the load (passengers and cargo)
for the vehicle. This is the max-
imum combined weight of occu- pants and cargo that can be
loaded into the vehicle. If the
vehicle is used to tow a trailer,
the trailer tongue weight must be
included as part of the cargo load.
This information is located on the
Tire and Loading Information la-
bel.
. Cargo capacity - permissible
weight of cargo, the weight of
total occupants weight subtracted
from the load limit.
VEHICLE LOADING INFORMATION

WARNING
A vehicle equipped with Four-Wheel
Drive (4WD) 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 4WD 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 and
Canadian Provinces, 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 battery is disconnected, the
vehicle may be reset to a “not ready condi-
tion”. Before taking the I/M test, check the
vehicle’s inspection/maintenance test readi- ness 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 condition is
“ready”.
It is recommended you visit an INFINITI
retailer to set “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
