INDICATORS FOR MAINTENANCE
1. Engine oil replacement indicator
This indicator appears when the customer
set time comes for changing the engine oil.
You can set or reset the distance for
changing the engine oil. (See“Trip compu-
ter” later in this section.)
2. Oil filter replacement indicator
This indicator appears when the customer
set time comes for replacing the oil filter.
You can set or reset the distance for
replacing the oil filter. (See “Trip compu-
ter” later in this section.)
3. Tire replacement indicator
This indicator appears when the customer
set distance comes for replacing tires. You
can set or reset the distance for replacing
tires. (See “Trip computer” later in this
section.)
WARNING
The tire replacement indicator is not a
substitute for regular tire checks, including
tire pressure checks. See “Changing wheels
and tires” in the“8. Maintenance and do-it- yourself”
section. Many factors including
tire inflation, alignment, driving habits and
road conditions affect tire wear and when
tires should be replaced. Setting the tire
replacement indicator for a certain driving
distance does not mean your tires will last
that long. Use the tire replacement indicator
as a guide only and always perform regular
tire checks. Failure to perform regular tire
checks, including tire pressure checks could
result in tire failure. Serious vehicle damage
could occur and may lead to a collision,
which could result in serious personal injury
or death.
4. “OTHER” indicator
This indicator appears when the customer
set time comes for replacing items other
than the engine oil, oil filter and tires. You
can set or reset the distance for replacing
the items. (See “Trip computer” later in
this section.)
More maintenance reminders are also
available on the center display. (See
“ How to use INFO button” in the“4.
Monitor, climate, audio, phone and voice
recognition systems” section.)

CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
. Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or elec-
trical systems can cause overrich fuel
flow into the three-way catalyst, causing
it to overheat. Do not keep driving if the
engine misfires, or if noticeable loss of
performance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly by an INFINITI retai-
ler.
. Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
. Do not race the engine while warming it
up.
. Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and it is the driver’
s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

Additional information
.The TPMS does not monitor the tire
pressure of the spare tire.
. The TPMS will activate only when the
vehicle is driven at speeds above 16
MPH (25 km/h). Also, this system may
not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is
inflated to the recommended pressure,
the vehicle must be driven at speeds
above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
. The CHECK TIRE PRESSURE warning
appears in the dot matrix liquid crystal
display when the low tire pressure
warning light is illuminated and low
tire pressure is detected. The CHECK
TIRE PRESSURE warning turns off when
the low tire pressure warning light
turns off.
The CHECK TIRE PRESSURE warning
appears each time the ignition switch
is placed in the ON position as long as the low tire pressure warning light
remains illuminated.
The CHECK TIRE PRESSURE warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
. Tire pressure rises and falls depending
on the heat caused by the vehicle’s
operation and the outside temperature.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If
the warning light illuminates in low
ambient temperature, check the tire
pressure for all four tires.
For additional information, see “Low tire
pressure warning light” in the“2. Instru-
ments and controls” section and“Tire
Pressure Monitoring System (TPMS) ”in
the “6. In case of emergency” section .
WARNING
.If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure shown
on the Tire and Loading Information
label to turn the low tire pressure
warning light OFF. If the light still
illuminates while driving after adjusting
the tire pressure, a tire may be flat. If
you have a flat tire, replace it with a
spare tire as soon as possible. (See
“Flat
tire” in the “6. In case of emergency”
section for changing a flat tire.)
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
. Replacing tires with those not originally
specified by INFINITI could affect the

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears on the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure (for
example a flat tire while driving).
For more details, see“Low tire pressure
warning light” in the“2. Instruments and
controls” section,“Tire Pressure Monitor-
ing System (TPMS)” in the“5. Starting and
driving” section and “Tire Pressure Mon-
itoring System (TPMS) ”in the “6. In case
of emergency” section.
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al-
ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
.Most tires naturally lose air over time.
.Tires can lose air suddenly whendriven over potholes or other
objects or if the vehicle strikes a
curb while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds.
WHEELS AND TIRES

Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.
WARNING
.Improperly inflated tires can fail
suddenly and cause an accident.
. The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.
S./C.M.V.S.S. certification label.
The vehicle weight capacity is
indicated on the Tire and Loading
Information label. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may re-
sult in reduced tire life, unsafe
operating conditions due to pre-
mature tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident.
Loading beyond the specified ca-
pacity may also result in failure of
other vehicle components. .
Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures
are at the specified level.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.

Checking the tire pressure
1.Remove the valve stem cap from
the tire.
2.Press the pressure gauge
squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position the gauge to eliminate
this leakage.
3.Remove the gauge.
4.Read the tire pressure on the
gauge stem and compare it to
the specification shown on the
Tire and Loading Information la-
bel.
5.Add air to the tire as needed. If
too much air is added, press the
core of the valve stem briefly with
the tip of the gauge stem to
release pressure. Recheck the
pressure and add or release air
as needed.
6.Install the valve stem cap.
7.Check the pressure of all other
tires, including the spare.

8-40Maintenance and do-it-yourself
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
construction and tread pattern. The tire
pressure and wheel alignment should also
be checked and corrected as necessary.
Contact an INFINITI retailer.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires,
refer to“Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
Care of wheels
See “Cleaning exterior” in the“Appearance
and care ”section for details about care of
the wheels.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire)
Observe the following precautions if the T-
type spare tire must be used, otherwise
your vehicle could be damaged or involved
in an accident.
WARNING
. The T-type spare tire should be used for
emergency use. It should be replaced
with the standard tire at the first
opportunity to avoid possible tire or
differential damage.
. Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
. Periodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire at
60 psi (420 kPa, 4.2 bar). Always keep
the pressure of the full size spare tire (if
so equipped) at the recommended pres-
sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see “Tire and Loading Informa- tion label”
in the index of this manual.
. With the TEMPORARY USE ONLY spare
tire installed do not drive your vehicle at
speeds faster than 50 MPH (80 km/h).
. When driving on roads covered with
snow or ice, the TEMPORARY USE ONLY
spare tire should be used on the front
wheels and original tire used on the rear
wheels (drive wheels). Use tire chains
only on the two rear original tires.
. Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than
the standard tire. Replace the spare tire
as soon as the tread wear indicators
appear.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire at
the same time.
CAUTION
.Do not use tire chains on a TEMPORARY
USE ONLY spare tire. Tire chains will not
fit properly and may cause damage to
the vehicle.

9-16Technical and consumer information
3.Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For exam-
ple, if the XXX amount equals
1400 lbs. and there will be five
150 lb. passengers in your vehi-
cle, the amount of available cargo
and luggage load capacity is 650
lbs. (1400−750 (5 x 150) = 650
lbs) or 640 −340 (5 x 70) = 300
kg.)
5.Determine the combined weight of
luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing a
trailer, load from your trailer will
be transferred to your vehicle.
Consult this manual to determine
how this reduces the available cargo and luggage load capacity
of your vehicle.
Before driving a loaded vehicle,
confirm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. (See “Mea-
surement of weights” later in this
section.)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
LOADING TIPS
.The GVW must not exceed GVWR or GAWR as specified on the F.M.V.
S.S./C.M.V.S.S. certification label.
.Do not load the front and rear axleto the GAWR. Doing so will exceed
the GVWR.
WARNING
. Properly secure all cargo to help
prevent it from sliding or shifting. Do not place cargo higher than the
seatbacks. In a sudden stop or
collision, unsecured cargo could
cause personal injury.
. Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear GAWRs.
If you do, parts of your vehicle can
break, tire damage could occur, or
it can change the way your vehicle
handles. This could result in loss
of control and cause personal
injury.
. Overloading could not only short-
en the life of your vehicle and the
tires, but also could lead to
hazardous vehicle handling and
long braking distance. This may
cause a premature tire malfunc-
tion, which could result in a
serious accident and personal in-
jury. Failures caused by overload-
ing are not covered by the
vehicle’s warranty.
