•Tires degrade with age and use. Have
tires, including the spare, over 6 years
old checked by a qualified technician be-
cause some tire damage may not be ob-
vious. Replace the tires as necessary to
prevent tire failure and possible per-
sonal injury.
•Improper service of the spare tire may
result in serious personal injury. If it is
necessary to repair the spare tire, it is
recommended that you visit an INFINITI
retailer for this service.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
Tires should be periodically inspected for
wear, cracking, bulging or objects caught in
the tread. If excessive wear, cracks, bulging
or deep cuts are found, the tire should be
replaced immediately.
The original tires have a built-in tread wear
indicator. When the wear indicator is visible,
the tire should be replaced.
Improper servicing of a tire may result in se-
rious personal injury. If it is necessary to re-pair a tire, it is recommended you contact an
INFINITI retailer.
TIRE ROTATION
INFINITI recommends rotating the tires ev-
ery 5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer to "Flat tire".As soon as
possible, tighten the wheel nuts to the speci-
fied torque with a torque wrench.
Wheel nut tightening torque: 96 ft-lb
(130 N·m)
The wheel nuts must be kept tightened to
specifications at all times. It is recommended
that wheel nuts be tightened to specification
at each tire rotation interval.
WARNING
•After rotating the tires, check and ad-
just the tire pressure.
•Do not include the spare tire in the tire
rotation.
•For additional information regarding
tires, refer to "Important Tire Safety
Information" (US) or "Tire Safety Infor-
mation" in the Warranty Information
Booklet.
REPLACING WHEELS AND TIRES
WARNING
Do not install a deformed wheel or tire even
if it has been repaired. Such wheels or tires
could have structural damage and could
fail without warning.
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. (See "Wheels and Tires"
for recommended types and sizes of tires and
wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to de-
creased braking efficiency and/or early brake
pad/shoe wear.
Confirm the following for the TPMS:
WARNING
•The use of tires other than those recom-
mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can

Parking brake*:
Check the parking brake operation regularly.
Also make sure that the vehicle is held se-
curely on a fairly steep hill when only the
parking brake is applied. If the parking brake
needs adjustment, it is recommended you
visit an INFINITI retailer for this service.
Seats:
Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches
lock securely in every position. Check that the
head restraints move up and down smoothly
and that the locks (if so equipped) hold se-
curely in all latched positions.
Seat belts:
Check that all parts of the seat belt system
(for example, buckles, anchors, adjusters and
retractors) operate properly and smoothly,
and are installed securely. Check the belt
webbing for cuts, fraying, wear or damage.
Steering wheel:
Check for changes in the steering condition,
such as excessive free play, hard steering or
strange noises.
Warning lights and chimes:
Make sure that all warning lights and chimes
are operating properly.Windshield defroster:
Check that the air comes out of the defroster
outlets properly and in good quantity when
operating the heater or air conditioner.
Windshield wiper and washer*:
Check that the wipers and washer operate
properly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*:
Except for maintenance free battery, check
the fluid level in each cell. It should be be-
tween the “UPPER” and “LOWER” lines.
NOTE
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic
accessories that consume battery power
when the engine is not running (Phone
chargers, GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.Brake fluid level*:
Make sure that the brake fluid level is be-
tween the “MAX” and “MIN” lines on the res-
ervoir.
Coolant level*:
Check the coolant level when the engine is
cold.
Engine drive belt(s)*:
Make sure that no belt is frayed, worn,
cracked or oily.
Engine oil level*:
Check the level after parking the vehicle on a
level spot and turning off the engine. Wait
more than 15 minutes for the oil to drain back
into the oil pan.
Exhaust system:
Make sure there are no loose supports,
cracks or holes. If the sound of the exhaust
seems unusual or there is a smell of exhaust
fumes, immediately have the exhaust system
inspected. It is recommended you visit an
INFINITI retailer for this service. See "Precau-
tions when starting and driving".
Fluid leaks:
Check under the vehicle for fuel, oil, water or
other fluid leaks after the vehicle has been

air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes
are evident, check for the cause and have it
corrected immediately.
Radiator and hoses:
Check the front of the radiator and clean off
any dirt, insects, leaves, etc., that may have
accumulated. Make sure the hoses have no
cracks, deformation, rot or loose connec-
tions.
Underbody:
The underbody is frequently exposed to cor-
rosive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust will
form on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information, see
"Cleaning exterior".
Windshield washer fluid*:
Check that there is adequate fluid in the res-
ervoir.The following descriptions are provided to
give you a better understanding of the sched-
uled maintenance items that should be regu-
larly checked or replaced. The maintenance
schedule indicates at which mileage/time in-
tervals each item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer to
"General maintenance" in this section.
Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You

VEHICLE LOADING INFORMATION
Technical information10-13

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 depressing
the accelerator and/or brake pedal.
•How fast the vehicle was traveling.
•Sounds are not recorded.
This data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.
NOTE: EDR data are recorded by your ve-
hicle only if a nontrivial crash situation occurs;
no data are recorded by the EDR under nor-
mal 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 EDRdata with the type of personally identifying
data routinely acquired during a crash inves-
tigation.
To read data recorded by an EDR, special
equipment is required and access to the ve-
hicle or the EDR is needed. In addition to the
vehicle manufacturer and INFINITI retailer,
other parties, such as law enforcement, that
have the special equipment, can read the in-
formation if they have access to the vehicle or
the EDR. EDR data will only be accessed with
the consent of the vehicle owner or lessee or
as otherwise required or permitted by law.Genuine INFINITI Service Manuals for this
model year and prior can be purchased. A
Genuine INFINITI Service Manual is the best
source of service and repair information for
your vehicle. This manual is the same one
used by the factory trained technicians work-
ing at INFINITI retailers. Genuine INFINITI
Owner’s Manuals can also be purchased.
