power steering INFINITI EX 2011 User Guide

●When towing rear wheel drive models with
the front wheels on the ground or on towing
dollies: Push the ignition switch to the ACC
or ON position, and secure the steering
wheel in a straight-ahead position with a
rope or similar device. For models with a
steering wheel lock mechanism: Never se-
cure the steering wheel by selecting the
LOCK position. This may damage the steer-
ing lock mechanism.
All-Wheel Drive (AWD) models
INFINITI recommends that towing dollies be
used when towing your vehicle or the vehicle be
placed on a flat bed truck as illustrated.
CAUTION
Never tow AWD models with any of the wheels
on the ground as this may cause serious and
expensive damage to the powertrain.

Warning lights and chimes:Make sure that all
warning lights and chimes are operating prop-
erly.
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 un-
der severe condition require frequent checks of
the battery fluid level.
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, immediately have the exhaust
system inspected 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 gasoline fumes are
evident, check for the cause and have it cor-
rected 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 ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
“CLEANING EXTERIOR” in the “7. Appearance
and care” section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.

5. Engine oil filler cap6. Brake fluid reservoir
7. Window washer fluid reservoir
8. Power steering fluid reservoir
9. Air cleaner
10. Drive belts
11. Engine coolant reservoir
The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze
and coolant protection. The antifreeze solution
contains rust and corrosion inhibitors. Addi-
tional engine cooling system additives are not
necessary.
WARNING
●
Never remove the radiator or coolant reser-
voir cap when the engine is hot. Wait until
the engine and radiator cool down. Serious
burns could be caused by high pressure fluid
escaping from the radiator. See precautions
in “IF YOUR VEHICLE OVERHEATS” in the “6.
In case of emergency” section of this
manual.
● The radiator is equipped with a pressure
type radiator cap. To prevent engine dam-
age, use only a genuine NISSAN radiator cap.

8-6Maintenance and do-it-yourself

When checking or replacement is required, we
recommend an INFINITI retailer for servicing.
CAUTION
●Use only Genuine NISSAN Matic S ATF. Do
not mix with other fluids.
● Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will cause
deterioration in driveability and automatic
transmission durability, and may damage
the automatic transmission, which is not
covered by the INFINITI new vehicle limited
warranty.
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 176°F (50 to 80°C) or
using the COLD range (
3: COLD MAX.,4:
COLD MIN.) at fluid temperatures of 32 to 86°F
(0 to 30°C). If the fluid is below the MIN line, add Genuine
NISSAN PSF or equivalent. Remove the cap and
fill through the opening.
CAUTION
●
Do not overfill.
● Use Genuine NISSAN PSF or equivalent.

Maintenance and do-it-yourself8-11

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

2. Alternator

5. Drive belt auto-tensioner
WARNING
Be sure the ignition switch is in the OFF or LOCK
position before servicing drive belts. The en-
gine could rotate unexpectedly.
1. Visually inspect each belt for signs of unusual wear, cuts, fraying or looseness.
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 con- dition and tension in accordance with the
maintenance schedule in your “INFINITI
Service and Maintenance Guide”.
