The outside air temperature mode includes a
low temperature warning feature. If the outside
air temperature is below 37°F (3°C), the warning
is displayed on the screen.
The outside temperature sensor is located in
front of the radiator. The sensor may be affected
by road or engine heat, wind directions and
other driving conditions. The display may differ
from the actual outside temperature or the
temperature displayed on various signs or bill-
boards.
6. Setting
Setting cannot be made while driving. A mes-
sage “Setting can only be operated when
stopped” is also displayed on the dot matrix
crystal display.

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.
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.
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
number to call (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada).

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 of 50% antifreeze and
50% demineralized or distilled water. 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. Refer to the INFINITI Service and Main-
tenance Guide for more details. The use of
other types of coolant solutions may damage
the engine cooling system.

CHECKING ENGINE COOLANT LEVEL
Check the coolant level in the reservoir when the
engine is cold. If the coolant level is below MIN
2, open the reservoir tank cap and add coolant
up to the MAX
1level. If the reservoir tank is
empty, check the coolant level in the radiator
when the engine is cold. If there is insufficient
coolant in the radiator, fill the radiator with
coolant up to the filler opening and also add it
to the reservoir tank up to the MAX level
1.
Tighten the cap securely after adding engine
coolant.
If the cooling system requires coolant fre-
quently, have it checked by an INFINITI retailer.
