To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less
than 1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit, and the CHECK TIRE PRES (pres-
sure) warning message is displayed in the
odometer, one or more of your tires is sig-
nificantly under-inflated. If the vehicle is be-
ing driven with low tire pressure, the TPMS
will activate and warn you of it by the low
tire pressure warning light. This system will
activate only when the vehicle is driven at
speeds above 16 mph (25 km/h). For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and Controls” section,
and “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” section
of this manual.

Failure to do so could result in damage
to the charging system and cause per-
sonal injury.

2. Apply the parking brake. Move the shif t lever to P (Park). Switch off all unneces-
sary electrical systems (lights, heater, air

adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.

In these cases, the battery may need to
be charged to maintain battery health.

level is between the MAX and MIN lines on
the reservoir. Engine coolant level*:
Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure the drive
belts are not frayed, worn, cracked or oily.

parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.

loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, refer to “Exhaust gas (carbon mon-
oxide)” in the “Starting and driving” section
of this manual.

and have it corrected immediately.
