TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (RPM).Do not rev
the engine into the red zone
*1.
CAUTION
When engine speed approaches the red
zone, shift to a higher gear or reduce engine
speed. Operating the engine in the red zone
may cause serious engine damage.

ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant
temperature.
The engine coolant temperature is within
the normal range when the gauge needle
points within the zone
*1shown in the
illustration.
The engine coolant temperature varies with
the outside air temperature and driving
conditions.
CAUTION
If the gauge indicates engine coolant
temperature near the hot (H) end of the
normal range, reduce vehicle speed to
decrease temperature. If gauge is over the
normal range, stop the vehicle as soon as
safely possible. If the engine is overheated,
continued operation of the vehicle may
seriously damage the engine. See “If your
vehicle overheats” (P.6-10) for immediate
action required.

the system then automatically changes
from the outside air circulation mode to
the recirculation mode.
When the intake air control button is
pushed under the following conditions,
the indicator light on the“
”side will
illuminate and the exhaust gas/outside
odor detecting sensor will turn on.
. The air flow control is not in the front
defroster mode (the indicator light on
the “
”front defroster button is
turned off).
. The outside temperature is about 328F
(08C) or more.
. The exhaust gas/outside odor detecting
sensor detects industrial odors such as
pulp or chemicals and exhaust gas
such as gasoline or diesel.
When the automatic intake air control is
ON, for the first 5 minutes, the recircula-
tion mode is selected to prevent dust, dirt
and pollen from entering the vehicle and
cleans the air inside of the vehicle with
Plasmacluster
®ions that are emitted from
the ventilator.
After 5 minutes, the sensor detects outside
odor and exhaust gas and automatically
alternates between the recirculation mode
and outside air circulation mode.
OPERATING TIPS
When the engine coolant temperature and
outside air temperature are low, the air
flow from the foot outlets may not operate.
This is not a malfunction. After the coolant
temperature warms up, air will flow nor-
mally from the foot outlets.

COLD WEATHER DRIVING

ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist
with cold temperature starting.
The engine block heater should be used
when the outside temperature is 208F
(−78C) or lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours,
depending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
WARNING
. Do not use your engine block heater with
an ungrounded electrical system or a 2-
pronged adapter. You can be seriously
injured by an electrical shock if you use
an ungrounded connection.
. Disconnect and properly store the en-
gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
. Use a heavy-duty 3-wire, 3-pronged
extension cord rated for at least 10A.
Plug the extension cord into a Ground
Fault Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the proper
extension cord or a grounded outlet can
result in a fire or electrical shock and
cause serious personal injury.

3. If engine overheating is caused by climbing 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
radiator 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 cool-
ant is leaking 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
reservoir tank if necessary. Have your
vehicle repaired at the nearest INFINITI
retailer. When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from an

TOWING YOUR VEHICLE

This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). 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 Maintenance
Guide for more details.
If the cooling system requires coolant
frequently, have it checked by an INFINITI
retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be
performed by an INFINITI retailer. The
service procedures can be found in the
appropriate 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
engine is hot.
. Never remove the radiator 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 reach of children and
pets.
Engine coolant must be disposed of
properly. Check your local regulations.
