WARNING
The tire replacement indicator is not a
substitute for regular tire checks, includ-
ing tire pressure checks. See “Changing
wheels and tires” (P.8-34). Many fac-
tors 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 pres-
sure 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.
3. 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

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials away
from the exhaust system compo-
nents.
.Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
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. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrichfuel 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 in-
spected promptly. It is recommended
you visit an INFINITI retailer for this
service.
.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
SYSTEM (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 Mon-
itoring 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.
For models with run-flat tires, if the vehicle
is being driven with one or more flat tires,
the low tire pressure warning light will
illuminate continuously and a chime will
sound for 10 seconds. The flat tire warning
will also appear in the vehicle information
display. The chime will only sound at the first
indication of a flat tire, and the warning light
will illuminate continuously. When the flat
tire warning is activated, it is recommended
you have the system reset and the tire
checked and replaced if necessary by an
INFINITI retailer. Even if the tire is inflated
to the specified COLD tire pressure, the
warning light will continue to illuminate until
the system is reset by an INFINITI retailer.
Your vehicle can be driven for a limited time
on a flat tire. See “Run-flat tires” (P.8-32).
Starting and driving5-5

5-6Starting and driving
Please note that the TPMS is not a sub-
stitute 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 illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended. TPMS malfunctions 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 properly. 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
.Since the spare tire (if so equipped) is not
equipped with the TPMS, 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 “Tire Pressure Low - Add Air”
warning appears in the vehicle informa-
tion display when the low tire pressure
warning light is illuminated and low tire
pressure is detected. The “Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light turns
off.
The “Tire Pressure Low - Add Air”
warning does not appear if the low tire
pressure warning light illuminates to
indicate a TPMS malfunction..The “Flat Tire - Visit dealer” warning (if
so equipped) appears in the vehicle
information display when the low tire
pressure warning light is illuminated and
one or more flat tires are detected.
.Tire pressure rises and falls depending on
the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure after driving
because the tire pressure rises after
driving. 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 illumi-
nate. 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) in the vehicle
information display. (See “Vehicle infor-
mation display” (P.2-20).)
.After the ignition switch is placed in the
ON position, it may take a period of time
for the tire pressure to be displayed while
the vehicle is driven. Depending on the
radio wave circumstance, tire pressure
may not correctly be displayed.
For additional information, see “Low tire
pressure warning light” (P.2-15) and “Tire
Pressure Monitoring System (TPMS)” (P.6-
3).

5-8Starting and driving
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 recep-
tion 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 examples
are:
.Facilities or electric devices using similar
radio frequencies are near the vehicle.
.If a transmitter set to similar frequencies
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.
Low tire pressure warning light may illumi-
nate in the following cases.
.If the vehicle is equipped with a wheel
and tire without TPMS..If the TPMS has been replaced and the ID
has not been registered.
.If the wheel is not originally specified by
INFINITI.

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire,
the TPMS with Tire Inflation Indicator
provides visual and audible signals outside
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 ex-
ternal 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 (1 m) backward or
forward and try again.
If the Tire Inflation Indicator is not working,
use a tire pressure gauge.AVOIDING COLLISION AND
ROLLOVER
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 excessive
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
drowsiness). Always wear your seat belt as
outlined in the “Seat belts” (P.1-11) 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 issignificantly more likely to be injured or
killed than a person properly wearing a seat
belt.
OFF-ROAD RECOVERY
If driving the right side or left side wheels
may unintentionally leave the road surface.
Maintain control of the vehicle by following
the procedure below. Please note that this
procedure is only a general guide. The vehicle
must be driven as appropriate based on the
conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering
wheel with both hands and try to hold
a straight course.
4. When appropriate, slowly release the
accelerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the
vehicle to follow the road while the
vehicle speed is reduced. Do not attempt
to drive the vehicle back onto the road
surface until vehicle speed is reduced.
6. When it is safe to do so, gradually turn
the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to stay
in the appropriate driving lane.

Pressure Monitoring System (TPMS)” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires (in-
cluding the spare) often and always
prior to long distance trips. The
recommended tire pressure specifica-
tions 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 when
driven over potholes or other ob-
jects 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” (P.5-8) about the
TPMS with Tire Inflation Indicator.)
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING
.Improperly inflated tires can fail
suddenly and cause an accident.
.The Gross Vehicle Weight rat-
ing (GVWR) is located on the F.
M.V.S.S./C.M.V.S.S. label. The
vehicle weight capacity is indi-
cated on the Tire and Loading
Information label. Do not load
your vehicle beyond this capa-
city. Overloading your vehicle
may result in reduced tire life,
unsafe operating conditions
due to premature tire failure,
or unfavorable handling char-acteristics and could also lead
to a serious accident. Loading
beyond the specified capacity
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 re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (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, reposition 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 label.
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. Check the pressure when driving
the vehicle at speeds of 100 MPH
(160 km/h) or higher where it is
legal to do so.
WARNING
.Driving at high speeds, 100
MPH (160 km/h) or higher
sustained where it is legal to
do so, can cause tires to have
excessive heat build up, which
may result in a tire failurecausing loss of control, crash,
injuries or even death. Some
high-speed rated tires require
inflation pressure adjustment
for high-speed operation.
When speed limits and road
conditions allow vehicle driving
at high speeds, make sure tires
are rated to support high speed
operation, tires are in optimal
conditions and pressure is ad-
justed to correct cold inflation
pressure for high speed opera-
tion.
.Tires require adjustment to the
inflation pressure when driving
the vehicle at speeds of 100
MPH (160 km/h) or higher
where it is legal to do so. See
recommended tire inflation
chart for correct operating
pressure.
.After vehicle high speed opera-
tion has ended, readjust the tire
pressure to the recommended
cold inflation pressure. (See
“Checking the tire pressure”
