heater INFINITI QX 2010 User Guide

Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make 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 defroster Check 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) .
Battery* Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
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. 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 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 dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
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 imme-
diately.
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 from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid* Check that there is
adequate fluid in the reservoir.

If the cooling system frequently requires
coolant, have it checked by an INFINITI
dealer.
CHANGING ENGINE COOLANT
An INFINITI dealer can change the engine cool-
ant. The service procedure can be found in the
INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
●To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
● Never remove the radiator or engine
coolant reservoir cap when the engine
is hot. Serious burns could be caused
by high pressure fluid escaping from
the radiator.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
● Keep coolant out of the reach of chil-
dren and pets. Engine coolant must be disposed of properly.
Check your local regulations.CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply
the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way.
