Power steering warning light
Models with Direct Adaptive Steering :
When the ignition switch is in the ON
position, the power steering warning light
illuminates. After starting the engine, the
power steering warning light stays on for a
few seconds and turns off. This indicates
that Direct Adaptive Steering is operational.
Drive the vehicle after the power steering
warning light turns off.
If the power steering warning light illumi-
nates while driving, pull off the road to a
safe location and stop the vehicle. If the
power steering warning light turns off, you
can drive again. If the power steering
warning light continues to illuminate, it is
recommended you have Direct Adaptive
Steering checked by an INFINITI retailer.
(See “Direct Adaptive Steering type” (P.5-
128).)
Models with hydraulic pump electric power
steering :
When the ignition switch is in the ON
position, the power steering warning light
illuminates. After starting the engine, the
power steering warning light turns off. This
indicates that or hydraulic pump electric
power steering is operational.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate hydraulic pump electric power
steering is not functioning properly and
may need servicing. It is recommended you
have the hydraulic pump electric power
steering checked by an INFINITI retailer.
(See “Hydraulic pump electric power steering
type” (P.5-127).)
Models with electric power steering :

position, the power steering warning light
illuminates. After starting the engine, the
power steering warning light turns off. This
indicates the electric power steering is
operational.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the electric power steering is not
functioning properly and may need servicing.
It is recommended you have the electric
power steering checked by an INFINITI
retailer.

WARNING
Power steering fluid is poisonous and
should be stored carefully in marked
containers out of the reach of children.
Check the fluid level in the reservoir. The
fluid level should be checked when the fluid
is cold at fluid temperatures of 0 to 30°C (32
to 86°F). The fluid level can be checked with
the level gauge which is attached to the cap.
To check the fluid level, remove the cap. The
fluid level should be between the MAX
and MINlines. If the fluid is below the MIN
line, add
Genuine NISSAN E-PSF. Remove the cap
and fill through the opening.
CAUTION
. Do not overfill.
. Use Genuine NISSAN E-PSF or
equivalent. For further brake fluid information, see
“Capacities and recommended fluids/lubri-
cants” (P.10-2) of this manual.
WARNING
.
Use only new fluid from a sealed
container. Old, inferior or contami-
nated fluid may damage the brake
system. The use of improper fluids
can damage the brake system and
affect the vehicle’s stopping ability.
. Clean the filler cap before removing.
. Brake fluid is poisonous and should
be stored carefully in marked con-
tainers out of the reach of children.
CAUTION
Do not spill the fluid on painted surfaces.
This will damage the paint. If fluid is
spilled, wash the surface with water.

9-4Maintenance and schedules
Warning lights and chimes:Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and
that the wipers do not streak.
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).
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 condition 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 electro-
nic 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 MAX and MIN lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Intercooler coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after
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.
Exhaust system: Make 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. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4).)
Fluid leaks: Check 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 immediately.
Power steering fluid level* and lines:
Check
the level when the fluid is cold, with the
engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
