seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraint/headrest
moves up and down smoothly and that
the locks (if so equipped) hold securely in
all latched positions.
Steering wheel:Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
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 tempera- tures 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 dis-
charge 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.
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, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
in the “5. Starting and driving” section for
exhaust gas (Carbon monoxide).)
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 fuel 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,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as

Maintenance and do-it-yourself8-7
ENGINE COMPARTMENT CHECK LOCATIONS

SDI1765A
Check the fluid level in the reservoir.
The fluid level should be checked using the
HOT range (
*1: HOT MAX.,*2: HOT MIN.)
at fluid temperatures of 122 to 1768F (50
to 808C) or using the COLD range (
*3:
COLD MAX.,
*4: COLD MIN.) at fluid
temperatures of 32 to 868F(0to30 8C).
If the fluid is below the MIN line, add
Genuine NISSAN PSF or equivalent. Re-
move the cap and fill through the opening.
CAUTION
. Do not overfill.
. Use Genuine NISSAN PSF or equivalent.
For further brake fluid specification infor-
mation, see “Capacities and recommended
fuel/lubricants” in the“9. Technical and
consumer information” section of this
manual.
WARNING
. Use only new fluid from a sealed
container. Old, inferior or contaminated
fluid may damage the brake system. The
use of improper fluids can damage the
brake system and affect the vehicle’s
stopping ability.
. Be sure to clean the filler cap before
removing.
. Brake fluid is poisonous and should be
stored carefully in marked containers 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.
Maintenance and do-it-yourself8-13
POWER STEERING FLUID BRAKE FLUID

CAUTION
.Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
. Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.SDI2119

WARNING
Be sure the ignition switch is in the OFF or
LOCK position before servicing drive belts.
The engine could rotate unexpectedly.
1. Visually inspect each belt for signs of
unusual wear, cuts, fraying or loosen- ess. If the belt is in poor condition or
loose, have it replaced or adjusted by
an INFINITI retailer.
2. Have the belts checked regularly for condition and tension in accordance
with the maintenance schedule in your
“INFINITI Service and Maintenance
Guide”.
