tire pressure NISSAN ALTIMA SL 2018 Owners 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 af ter 1 minute. Have the sys-
tem checked. It is recommended that you
visit a NISSAN dealer 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
pressure” in the “Do-it-yourself ” section of
this manual.

Master warning light
When the ignition is in the ON position, the
master warning light illuminates if any of
the following are displayed on the vehicle
information display.∙ No key warning
∙ Low windshield-washer fluid warning
∙ Parking brake release warning
∙ Door/trunk open warning
∙ Loose fuel cap
∙ Low tire pressure warning

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 detect a sudden drop in tire pres-
sure (for example, a flat tire while driv-
ing).
∙ The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted on all four tires. Af-
ter all four tires are inflated to the rec-
ommended 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
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” warn-
ing 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” warn- ing does not appear if the low tire pres-
sure warning light illuminates to indi-
cate a TPMS malfunction.
∙ Tire pressure rises and falls depending on the heat caused by the vehicle’s op-
eration and the outside temperature.
Do not reduce the tire pressure af ter
driving because the tire pressure rises
af ter 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 illumi-
nates, 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 tire pressure of
all tires (except the spare) 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” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “In case of
emergency” section and “Tire pressure” in
the “Do-it-yourself ” section of this manual.

∙ If the low tire pressure warning lightilluminates 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. Driv-
ing with underinflated tires may per-
manently damage the tires and in-
crease 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 Infor-
mation label to turn the low tire pres-
sure warning light off. If you have a flat
tire, replace it with a spare tire as soon
as possible. (For additional informa-
tion, 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
replaced, tire pressure will not be indi-
cated, the TPMS will not function and
the low tire pressure warning light will
flash for approximately 1 minute. The
light will remain on af ter 1 minute. It is
recommended that you visit a NISSAN
dealer for tire replacement and/or
system resetting.
∙ Replacing tires with those not origi- nally specified by NISSAN 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 pres-
sure sensors.

If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.
AVOIDING COLLISION AND
ROLLOVER

Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, refer
to “Wheels and tires” in the “Do-it-yourself ”
section of this manual. If a tire rapidly loses
air pressure or “blows-out” while driving,
maintain control of the vehicle by following
the procedure below. Please note that this
procedure is only a general guide. The ve-
hicle must be driven as appropriate based
on the conditions of the vehicle, road and
traffic.

∙ Do not use the LDW system under thefollowing 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 un- even roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshif t or temporary 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 sus-
pension parts.
– When you are towing a trailer or other vehicle. ∙ The system may not function prop-
erly under the following conditions:
– On roads where there are multiple parallel lane markers; lane mark-
ers that are faded or not painted
clearly; yellow painted lane mark-
ers; 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 contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
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 direc- tion 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 adheres 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 aim-
ing 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 sunrise or sunset.)
– When a sudden change in bright- ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
SYSTEM TEMPORARILY
UNAVAILABLE
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then
started, the LDW system may be deacti-
vated automatically and the following
message will appear in the vehicle infor-
mation display: “Unavailable: High Cabin
Temperature.”

– When driving on roads where thetraveling lane merges or separates
or where there are temporary lane
markers because of road
construction
– When there is a lane closure due to road repairs
– When driving on a bumpy road sur- face, such as an uneven dirt road
– When driving on sharp curves or winding roads
– When driving on repeated uphill and downhill roads
∙ Do not use the Steering Assist under the following conditions because the
system will not operate properly:
– When driving with a tire that is not within normal tire conditions (for
example, tire wear, abnormal tire
pressure, installation of a spare
tire, tire chains, nonstandard
wheels)
– When the vehicle is equipped with non-original brake or suspension
parts – When an object such as a sticker or
cargo obstructs the camera
– When excessively heavy baggage is loaded in the rear seat or lug-
gage area of your vehicle
– When the vehicle load capacity is exceeded
– When towing a trailer or other vehicle
∙ Excessive noise will interfere with the warning chime sound, and the beep
may not be heard.
∙ For the ProPILOT Assist system to op- erate properly, the windshield in front
of the camera must be clean. Replace
worn wiper blades. The correct size
wiper blades must be used to help
make sure the windshield is kept
clean. Only use Genuine NISSAN wiper
blades, or equivalent wiper blades,
that are specifically designed for use
on your vehicle model and model
year. It is recommended that you visit
a NISSAN dealer for the correct parts
for your vehicle.Steering Assist temporary

The tire size message may be displayed if
there is a large difference between the di-
ameters of front and rear wheels. Pull off
the road in a safe area, with the engine
idling. Check that all tire sizes are the same,
that the tire pressure is correct and that
the tires are not excessively worn.
If any warning messages continue to be
displayed, have your vehicle checked. It is
recommended that you visit a NISSAN
dealer as soon as possible.

∙ If the tire size incorrect message isdisplayed while you are driving, pull
off the road in a safe area with the
engine idling. Check that all tire sizes
are the same, that the tire pressure is
correct and that the tires are not ex-
cessively worn.
∙ If a warning message continues to be displayed af ter the above operations,
have your vehicle checked as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
