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.8-36).
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 (if so
equipped).
. 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
appears in the vehicle information dis-
play when the low tire pressure warn-
ing 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
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) in the
vehicle information display. (See “Ve-
hicle information display” (P.2-20).)

5-100Starting and driving
6. Plan for the shortest route..Utilize a map or navigation system todetermine the best route to save
time.
7. Avoid idling.
.Shutting off your engine when safe for stops exceeding 30-60 seconds
saves fuel and reduces emissions.
8. Buy an automated pass for toll roads.
.Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and avoid
stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no more than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal
operating temperature more quickly
while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered
parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, result-
ing in reduced demand on your A/C
system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter
recommendation” (P.9-6).)
