2011 INFINITI G-COUPE air condition

3. If engine overheating is caused by climb-ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radia-
tor 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.
5. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
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 leak-
ing or the cooling fan does not run, stop
the engine.
WARNING
Be careful not to allow your hands, hair, jewelry
or clothing to come into contact with, or get
caught in, engine belts or the engine cooling
fan. The engine cooling fan can start at any
time.
7. After the engine cools down, check thecoolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at the nearest INFINITI retailer.
If needed, Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free

sion, axles, steering system and powertrain
are in working condition. If any unit is dam-
aged, dollies must be used.
● Always attach safety chains before towing.
TOWING YOUR VEHICLE
In case of emergency6-11

Your new INFINITI has been designed to have
minimum maintenance requirements with long
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your
INFINITI’s fine mechanical condition, as well as
its emission and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives the proper
maintenance care. You are a vital link in the
maintenance chain.
SCHEDULED MAINTENANCE
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your “INFINITI Service and
Maintenance Guide”. You must refer to that
guide to ensure that necessary maintenance is
performed on your INFINITI at regular intervals.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-to-
day operation. They are essential for propervehicle operation. It is your responsibility to
perform these procedures regularly as pre-
scribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
an INFINITI retailer.
WHERE TO GO FOR SERVICE
If maintenance service is required or your ve-
hicle appears to malfunction, have the systems
checked and serviced by an INFINITI retailer.
INFINITI technicians are well-trained specialists
and are kept up to date with the latest service
information through technical bulletins, service
tips, and in-retailership information systems.
They are completely qualified to work on
INFINITI vehicles
beforework begins.
You can be confident that an INFINITI retailer’s
service department performs the best job to
meet the maintenance requirements on your
vehicle — in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have an
INFINITI retailer do it promptly. In addition, you
should notify an INFINITI retailer if you think
that repairs are required.
When performing any checks or maintenance
work, see “MAINTENANCE PRECAUTIONS” later
in this section.EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following items
with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood:
Check that all doors
and the engine hood, operate properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary latch
keeps the hood from opening when the primary
latch is released.
MAINTENANCE REQUIREMENT GENERAL MAINTENANCE

restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Steering wheel:Check for changes in the steer-
ing 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 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.

8-22Maintenance and do-it-yourself

If you have a flat tire, see “FLAT TIRE” in the “6. In
case of emergency” section.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires except the spare. When the
low tire pressure warning light is lit and the
CHECK TIRE PRESSURE warning appears on the
dot matrix liquid crystal display, one or more of
your tires is significantly under-inflated.
The TPMS will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h). Also,
this system may not detect a sudden drop in tire
pressure (for example a flat tire while driving).
For more details, see “Low tire pressure warn-
ing light” in the “2. Instruments and controls”
section, “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “5. Starting and driving” section
and “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “6. In case of emergency” sec-
tion.
Tire inflation pressure
Check the pressure of the tires (includ-
ing the spare) often and always prior to
long distance trips. The recommended
tire pressure specifications are shown
on the Tire and Loading Information
label under the “Cold Tire Pressure”
heading. The Tire and Loading Informa-
tion label is affixed to the driver side
center pillar. Tire pressures should be
checked regularly because:
●Most tires naturally lose air over time.
●Tires can lose air suddenly when
driven over potholes or other objects
or if the vehicle strikes a curb while
parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds. Incorrect tire pressure, including under
inflation, may adversely affect tire life
and vehicle handling.
WARNING
●Improperly inflated tires can fail sud-
denly and cause an accident.
●The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.S./
C.M.V.S.S. label. The vehicle weight
capacity is indicated on the Tire and
Loading Information label. Do not
load your vehicle beyond this capac-
ity. Overloading your vehicle may re-
sult in reduced tire life, unsafe operat-
ing conditions due to premature tire
failure, or unfavorable handling char-
acteristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
