MAINTENANCE INDICATORS
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.
. You can also check the pressure of all
tires (except the spare tire) on the
display screen. The order of the tire
pressure figures displayed on the
screen does not correspond with the
actual order of the tire position. See
“TIRE PRESSURE information” in the“4.
Monitor, climate, audio, phone and
voice recognition systems” section.
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 or LOW PRESSURE informa-
tion is displayed on the monitor screen
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 fail-
ure. 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
Starting and driving5-5

5-6Starting and driving
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
proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CAUTION
.The TPMS may not function properly
when the wheels are equipped with tire
chains or the wheels are buried in snow.
. Do not place metalized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the
signals from the tire pressure sensors, and the TPMS will not function properly.
Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate. Some exam-
ples are:
.
Facilities or electric devices using simi-
lar radio frequencies are near the
vehicle.
. If a transmitter set to similar frequen-
cies is being used in or near the
vehicle.
. If a computer (or similar equipment) or
a DC/AC converter is being used in or
near the vehicle.

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire,
the TPMS with Tire Inflation Indicator
provides visual and audible signals out-
side the vehicle to help you inflate the tires
to the recommended COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shift lever in the P (Park) position.
3. Place the ignition switch in the ON position. Do not start the engine.

Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indica-tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire.
. If the tire is over-inflated more than
approximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash 3
times. To correct the pressure, push the
core of the valve stem on the tire briefly
to release pressure. When the pressure
reaches the designated pressure, the
horn beeps once.
. If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates
that the Tire Inflation Indicator is not
operating.
. The TPMS will not activate the Tire
Inflation Indicator under the following
conditions:
— If there is interference from an
external device or transmitter
— The air pressure from the inflation
device such as those using a power socket is not sufficient to inflate the
tire
— If an electrical equipment is being
used in or near the vehicle
— There is a malfunction in the TPMS
system
— There is a malfunction in the horn or
hazard indicators
. If the Tire Inflation Indicator does not
operate due to TPMS interference,
move the vehicle about 3 ft (1m)
backward or forward and try again.
If the Tire Inflation Indicator is not working,
use a tire pressure gauge.
AVOIDING COLLISION AND ROLL-
OVER
WARNING
Failure to operate this vehicle in a safe and
prudent manner may result in loss of control
or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid exces-
sive speed, high speed cornering, or
sudden steering maneuvers, because these driving practices could cause you to
lose control of your vehicle.
As with any
vehicle, a loss of control could result in a
collision with other vehicles or objects, or
cause the vehicle to rollover, particularly if
the loss of control causes the vehicle to
slide sideways. Be attentive at all times,
and avoid driving when tired. Never drive
when under the influence of alcohol or
drugs (including prescription or over-the-
counter drugs which may cause drowsi-
ness). Always wear your seat belt as
outlined in the “Seat belts”in the“1.
Safety —seats, seat belts and supple-
mental restraint system” section of this
manual, and also instruct your passengers
to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash,
an unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.

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 in 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.

TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. (See“TPMS with Tire Infla-
tion Indicator” in the“5. Starting and
driving” section about the TPMS with
Tire Inflation Indicator.)
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.
