TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
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
“Tire Pressure Low – Add Air” warning
appears in the vehicle information dis-
play, one or more of your tires is sig-
nificantly under-inflated. If equipped,
the system also displays pressure of all
tires (except the spare tire) on the dis- play screen by sending a signal from a
sensor that is installed in each wheel.
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 additional information, refer to
“Low tire pressure warning light” in the
“Instruments and controls” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving”
section and “Flat tire” in the “In case of
emergency” section of this manual.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label or the Tire and Loading In-
formation label under the “Cold Tire
Pressure” heading. The Tire and Load-
ing Information label is affixed to thedriver 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 mod-
erate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
refer to “TPMS with tire inflation indi-
cator” in the “Starting and driving” sec-
tion of this manual.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.

ing” section of this manual.
Low tire pressure warninglight
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors the
tire pressure of all tires except the spare.
The low tire pressure warning light warns of
low tire pressure or indicates that the TPMS
is not functioning properly.
After the ignition switch is placed in the ON
position, this light illuminates for about 1 sec-
ond and turns off.
Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illuminate. A
“Tire Pressure Low - Add Air” warning also
appears in the vehicle information display. When the low tire pressure warning light il-
luminates, you should stop and adjust the
tire pressure of all four tires to the recom-
mended COLD tire pressure shown on the
Tire and Loading Information label located in
the driver’s door opening. The low tire pres-
sure 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 each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains illumi-
nated.
For additional information, refer to “Vehicle
information display” in the “Instruments and
controls” section and “Tire Pressure Monitor-
ing System (TPMS)” in the “Starting and driv-
ing” section and in the “In case of emergency”
section of this manual.
TPMS malfunction
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The light
will remain on after 1 minute. Have the sys-
tem checked. It is recommended that you visit
an INFINITI retailer for this service. The "Tire
Pressure Low — Add Air" warning does not
appear if the low tire pressure warning light
illuminates to indicate a TPMS malfunction.
For additional information, refer to “Tire
Pressure Monitoring System (TPMS)” in the
“Starting and driving” section and “Tire pres-
sure” in the “Do-it-yourself” section of this
manual.
WARNING
∙ Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
∙ If the light does not illuminate with the ignition switch placed in the ON position,
have the vehicle checked as soon as pos-
sible. It is recommended that you visit an
INFINITI retailer for this service.
2-12Instruments and controls

∙ If the 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 perma-
nently 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 per-
sonal injury or death. Check the tire pres-
sure for all four tires. Adjust the tire pres-
sure to the recommended COLD tire
pressure show on the Tire and Loading
Information label located in the driver’s
door opening to turn the low tire pressure
warning light OFF. If the light still illumi-
nates 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 replace-
ment tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service. ∙ When replacing a wheel without the
TPMS such as the spare tire, 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 that you visit
an INFINITI retailer for these services.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
∙ The TPMS is not a substitute for theregular tire pressure check. Be sure to
check the tire pressure regularly.
∙ If the vehicle is being driven at speeds of less than 16 mph (25 km/h), the TPMS
may not operate correctly.
∙ Be sure to install the specified size of tires to the four wheels correctly.
Master warning light
When the ignition switch is in the ON posi-
tion, the master warning light illuminates if
any of the following (if so equipped) are dis-
played on the vehicle information display: ∙ No key warning
∙ I-Key system warning
∙ Low fuel warning
∙ Low washer fluid warning
∙ Parking brake warning
∙ Door/ liftgate open warning

Instruments and controls2-13

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will 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 electrical
systems can cause over rich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that 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 Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all 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 driv-
er’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 combined
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 se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels al-
low the TPMS to continue to function prop-
erly.
Starting and driving5-5

Additional information:∙ When replacing a wheel without the TPMS such as the spare tire, 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 de-
tect 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 in-
flated 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” warn- ing appears in the vehicle information
display when the low tire pressure warn-
ing light is illuminated and low tire pres-
sure 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” warn-
ing appears each time the ignition switch
is in the ON position as long as the low
tire pressure warning light remains illumi-
nated.
∙ The “Tire Pressure Low — Add Air” warn- ing does not appear if the low tire pres-
sure 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 be-
cause 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 illuminate. If the
warning light illuminates, check the tire
pressure for all four tires.
∙ The Tire and Loading Information label is located in the driver’s door opening.
∙ You can also check the pressure of all tires (except the spare tire) on the vehicle
information display screen. The order of
the tire pressure figures displayed on the
screen corresponds with the actual order
of the tire position. For additional information, refer to “Low tire
pressure warning light” and “Tire Pressure
Low — Add Air” in the “Instruments and con-
trols” section and “Tire Pressure Monitoring
System (TPMS)” in the “In case of emergency”
section of this manual.
WARNING
∙ Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
5-6Starting and driving

∙ If the low tire pressure warning light illu-minates 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 recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
off. If you have a flat tire, replace it with a
replacement tire as soon as possible. (For
additional information, refer to “Flat
tire” in the “In case of emergency” section
for changing a flat tire.) ∙ When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is re-
placed, tire pressure will not be indicated,
the TPMS will not function and the low
tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Have your tires
replaced and/or TPMS system reset as
soon as possible. It is recommended that
you visit an INFINITI retailer for this
service.
∙ 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 properlywhen 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 sig-
nals from the tire pressure sensors, and
the TPMS will not function properly. Some devices and transmitters may tempo-
rarily interfere with the operation of the
TPMS and cause the low tire pressure warn-
ing 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.
The low tire pressure warning light may illu-
minate 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.
Starting and driving5-7

∙ The system will not operate at speeds be-low approximately 37 mph (60 km/h) or
if it cannot detect lane markers.
∙ Do not use the LDW system under the following conditions as it may not func-
tion properly:
– During bad weather (rain, fog, snow, etc.).
– When driving on slippery roads, such as on ice or snow.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift or tempo- rary lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire conditions (for example, tire wear, low
tire pressure, installation of spare tire,
tire chains, nonstandard wheels).
– When the vehicle is equipped with non-original brake parts or suspen-
sion parts.
– When you are towing a trailer or other vehicle. The system may not function properly under
the following conditions:
∙ On roads where there are multiple paral- lel lane markers; lane markers that are
faded or not painted clearly; yellow
painted lane markers; non-standard lane
markers; or lane markers covered with
water, dirt, snow, etc.
∙ On roads where the discontinued lane markers are still detectable.
∙ On roads where there are sharp curves.
∙ On roads where there are sharply con- trasting objects, such as shadows, snow,
water, wheel ruts, seams or lines remain-
ing after road repairs. (The LDW system
could detect these items as lane markers.)
∙ On roads where the traveling lane merges or separates.
∙ When the vehicle’s traveling direction does not align with the lane marker.
∙ When traveling close to the vehicle in front of you, which obstructs the lane
camera unit detection range.
∙ When rain, snow, dirt or an object ad- heres to the windshield in front of the
lane camera unit. ∙ When the headlights are not bright due to
dirt on the lens or if the aiming is not
adjusted properly.
∙ When strong light enters the lane camera unit. (For example, the light directly
shines on the front of the vehicle at sun-
rise or sunset.)
∙ When a sudden change in brightness oc- curs. (For example, when the vehicle en-
ters or exits a tunnel or under a bridge.)
SYSTEM TEMPORARILY

LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDP system. Failure to follow the warn-
ings and instructions for proper use of the
LDP system could result in serious injury or
death.
∙ The LDP system may activate if youchange lanes without first activating
your turn signal or, for example, if a con-
struction zone directs traffic to cross an
existing lane marker. If this occurs you
may need to apply corrective steering to
complete your lane change.
∙ Because the LDP may not activate under the road, weather, and lane marker con-
ditions described in this section, it may
not activate every time your vehicle be-
gins to leave its lane and you will need to
apply corrective steering.
∙ The LDP system will not operate at speeds below approximately 37 mph
(60 km/h) or if it cannot detect lane
markers.
∙ Do not use the LDP system under the fol- lowing conditions as it may not function
properly: – During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such as on ice or snow.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift or tempo- rary lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire conditions (for example, tire wear, low
tire pressure, installation of spare tire,
tire chains, non-standard wheels).
– When the vehicle is equipped with nonoriginal brake parts or suspension
parts.
– When you are towing a trailer or other vehicle.
The system may not function properly un-
der the following conditions: ∙ On roads where there are multiple paral-
lel lane markers; lane markers that are
