CAUTION
●CVT models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
●Do not push start this vehicle. The 3-way
catalyst may be damaged.
WARNING
●Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
●To avoid the danger of being scalded,
never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
●Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , or if you
feel a lack of engine power, detect abnormal
noise, etc. take the following steps.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever to
P (Park) .
Do not turn the NISSAN PUREDRIVE™
Hybrid System off.2. Turn off the air conditioner. Open all the
windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed.
3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. If steam or coolant
is escaping, turn off the engine. Do not open
the hood further until no steam or coolant
can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Also check if the cooling fan is running. The
radiator hoses and radiator should not leak
water. If the coolant is leaking or the cooling
fan does not run, stop the hybrid system.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.

and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimesMake sure all
warning lights and chimes are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
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.
