5. Outside air temperature (ICY — °F
or °C) The outside air temperature is displayed in °F or
°C in the range of  22 to 131°F (  30 to 55°C).

CAUTION● Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
● To avoid the danger of being scalded, never
remove the radiator cap while the engine is
still hot. When the radiator cap is removed,
pressurized hot water will spurt out, possi-
bly causing serious injury.
● Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply
the parking brake and move the selector
lever to the P (Park) position (Automatic
transmission models). Move the shift lever
to the N (Neutral) position (Manual trans-
mission models).
Do not stop the engine.
2. Turn off the climate control. Open all the
windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 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.
WARNINGIf 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. WARNINGBe 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 the
coolant 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.

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.

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze
coolant solution. The antifreeze solution con-
tains rust and corrosion inhibitors, therefore
additional cooling system additives are not
necessary.
WARNING● Never remove the radiator cap when the en-
gine is hot. Wait until the engine and radia-
tor 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. CAUTION● When adding or replacing coolant, be sure to
use only a Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent with
the proper mixture ratio shown in the follow-
ing chart. The life expectancy of the factory-
fill coolant is 105,000 miles (168,000 km) or
7 years. Mixing any other type of coolant or
the use of non-distilled water will reduce the
life expectancy of the factory-fill coolant. Re-
fer to the Infiniti Service and Maintenance
Guide for more details. The use of other
types of coolant solutions may damage the
engine cooling system.
● The coolant reservoir is equipped with a
pressure type radiator cap. To prevent en-
gine damage, use only a genuine NISSAN
coolant reservoir cap.

(168,000 km) or 7 years. Mixing any other type
of coolant or the use of non-distilled water will
reduce the life expectancy of the factory-fill
coolant. Refer to the INFINITI Service and Main-
tenance Guide for more details.
If the cooling system requires coolant fre-
quently, have it checked by an INFINITI retailer.
CHANGING ENGINE COOLANT Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate INFINITI
Service Manual.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING● To avoid the danger of being scalded, never
change the coolant when the engine is hot.
● Never remove the radiator cap when the en-
gine 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 reach of children 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. Run the engine until it reaches operating
temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.
5. Remove the dipstick again and check the
oil level. It should be within the range
 1
.
If the oil level is below
 2
, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill
