Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
12–volt Battery*Except for maintenance-free
battery, check the fluid level in each cell. It should
be between the MAX and MIN lines. Vehicles
operated in high temperatures or under severe
conditions require frequent checks of the battery
fluid level.NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic
accessories that consume battery power
when the engine is not running (Phone
chargers, GPS, DVD players, etc.) .
2. Vehicle is not driven regularly and/or
only driven short distances. In these cases,
the battery may need to be charged to
maintain battery health.
Brake fluid level*Make sure that the brake fluid
level is between the MIN and MAX lines on the
reservoir.
Engine coolant level*Check the coolant level
when the engine is cold. Make sure that the
coolant level is
between theMAXandMINlines on the reser-
voir.
Inverter coolant level*Check the coolant level
when the inverter is cold. Make sure the coolant
level is between the “MAX” and “MIN” lines on the
reservoir.
Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust systemMake sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. For addi-
tional information, refer to the carbon monoxide
warning in the “Starting and driving” section of
this manual.
Fluid leaksCheck under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.
Power steering fluid level* and linesCheck
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
8-4Maintenance and do-it-yourself

UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. For
additional information, refer to “Appearance and
care” section of this manual.
Windshield-washer fluid*Check that there is
adequate fluid in the reservoir.When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.

●If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
●Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
●Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
●The fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
