5-4Starting and driving
WARNING
.Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
. 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 colli-
sion, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death. .
If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
. Do not run the engine in closed spaces
such as a garage.
. Do not park the vehicle with the
engine running for any extended
length of time.
. Keep the liftgate closed while driving,
otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the
liftgate open, follow these precau-
tions:
1) Open all the windows.
2) Set the
air recirculation to
off and the fan control to high to
circulate the air.
. If electrical wiring or other cable
connections must pass to a trailer
through the seal on the liftgate or the
body, follow the manufacturer’s re-
commendation to prevent carbon
monoxide entry into the vehicle.
. The exhaust system and body should
be inspected by a qualified mechanic
whenever:
— The vehicle is raised for service. — You suspect that exhaust fumes
are entering into the passenger
compartment.
— You notice a change in the sound of the exhaust system.
— You have had an accident invol- ving damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
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.
PRECAUTIONS WHEN STARTING
AND DRIVING

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 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 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.
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 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
Starting and driving5-5

5-6Starting and driving
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 information dis-
play 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
appears each time the ignition switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
The “Tire Pressure Low Add Air” 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 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) on the vehicle
information display. (See “10. Tire pres-
sures” (P.2-36).)
For additional information, see “Low tire
pressure warning light” (P.2-16) and “Tire
Pressure Monitoring System (TPMS) ” (P.6-
3).
WARNING
. If the low tire pressure warning light
illuminates while driving, avoid sud-
den 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 or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a spare tire as soon as
possible. If no tire is flat and all tires
are properly inflated, it is recom-
mended you consult an INFINITI
retailer.
. Since the spare tire is not equipped
with the TPMS, 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. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally 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
