dipstick to check the oil level. See “Engine oil” in
the “Maintenance and do-it-yourself” section of
this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
Intelligent Key system warning
light
The Intelligent Key system warning light warns of
a malfunction with the electrical steering lock
system or the Intelligent Key system.
After the ignition switch is pushed to the ON
position, this light comes on for about 2 seconds
and then turns off.
If the light comes on while the engine is stopped,
it may not be possible to free the steering lock or
to start the engine. If the light comes on while the
engine is running, you can drive the vehicle. How-
ever, in these cases, contact a Nissan dealer for
repair as soon as possible.
See “Intelligent Key system” in the “Pre-driving
checks and adjustments” section.
Low tire pressure warning
light
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 turned ON, this light
illuminates for about 1 second and turns off.
Low tire pressure warning:
If the vehicle is being driven with low tire pres-
sure, the warning light will illuminate.
When the low tire pressure warning light illumi-
nates, you should stop and adjust the tire pres-
sure to the recommended COLD tire pressure
shown on the Tire and Loading Information label.
The low tire pressure warning light does not
automatically turn off when the tire pressure is
adjusted. After the tire is inflated to the recom-
mended pressure, the vehicle must be driven
over 16 MPH (25 km/h) to activate the TPMS and
turn off the low tire pressure warning light. Use a
tire pressure gauge to adjust tire pressure to the
recommended pressure.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and in the “In case of emergency”
section.
TPMS malfunction:
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
turned ON. The light will remain on after the 1
minute. Have the system checked by a NISSAN
dealer.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section.
WARNING
● If the light does not illuminate with the
ignition switch turned ON, have the ve-
hicle checked by a NISSAN dealer as
soon as possible.
