Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for repairs.
Otherwise, have your vehicle towed
because driving it could be
dangerous. ∙ Pressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort and pedal travel.
∙ If the brake fluid level is below the MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked. It is
recommended that you visit a NISSAN
dealer for this service.

Low tire pressure warninglight
Your vehicle is equipped with a 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.
Af ter the ignition switch is placed in the ON
position, this light illuminates for about
1 second and turns off.
Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illumi-
nate. A “Tire Pressure Low - Add Air”
warning also appears in the vehicle in-
formation display (if so equipped).
When the low tire pressure warning light
illuminates, you should stop and adjust
the tire pressure of all four tires to the
recommended COLD tire pressure shown
on the Tire and Loading Information la-
bel located in the driver’s door opening.
The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. Af ter 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.
For vehicles with a vehicle information dis-
play, 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 illumi-
nated.
For additional information, refer to “Vehicle
information display” in this section, “Tire
Pressure Monitoring System (TPMS)” in the
“Starting and driving” and “In case of emer-
gency” sections of this manual.

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
system 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

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 in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult in serious personal injury or
death. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pressure
show on the Tire and Loading Infor-
mation label located in the driver’s
door opening to turn the low tire pres-
sure warning light off. If the light still
illuminates while driving af ter adjust-
ing 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 in-
flated, have the vehicle checked. It is
recommended that you visit a NISSAN
dealer for this service. ∙ When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for these services.
∙ Replacing tires with those not origi- nally specified by NISSAN 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.
