TACHOMETER
The tachometer indicates engine speed in revo-
lutions 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 tem-
perature.
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 tempera-
ture 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 ve-
hicle may seriously damage the engine. See “IF
YOUR VEHICLE OVERHEATS” in the “6. In case of
emergency” section for immediate action
required.

OPERATING TIPS
When the engine coolant temperature and out-
side air temperature are low, the air flow from
the foot outlets may not operate. However, this
is not a malfunction. After the coolant tempera-
ture warms up, the air flow from the foot outlets
will operate normally.
The sensors
AandBlocated on the instru-
ment panel help maintain a constant tempera-
ture. Do not put anything on or around the
sensors.
IN-CABIN MICROFILTER
Models without Advanced Climate Control Sys-
tem:
The climate control system is equipped with an
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure the air conditioner
heats, defogs, and ventilates efficiently, replace
the filter in accordance with the maintenance
schedule in the INFINITI Service and Mainte-
nance Guide. To replace the filter, contact an
INFINITI retailer.
The filter should be replaced if air flow is ex-
tremely decreased or when windows fog up eas-
ily when operating heater or air conditioning
system. Models with Advanced Climate Control System:
The climate control system is equipped with a
natural grape seed polyphenol filter which col-
lects and neutralizes dirt, pollen, dust, etc. To
make sure that the air conditioner heats, defogs
and ventilates efficiently, replace the filter in
accordance with the maintenance schedule in
the INFINITI Service and Maintenance Guide. To
replace the filter, contact an INFINITI retailer.
The filter should be replaced if the air flow de-
creases significantly or if windows fog up easily
when operating the heater or air conditioner.SAA3088

5. To stop the engine, shift the selector leverto the P (Park) position and push the
ignition switch to the OFF position.ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant
temperature becomes too high (for example,
when climbing steep grades in high tempera-
ture with heavy loads, such as when towing a
trailer).
When the engine temperature reaches a certain
level:
● The engine coolant temperature gauge will
move toward the H position.
● Engine power may be reduced.
● The air conditioning cooling function may be
automatically turned OFF for a short time
(the blower will continue to operate).
Engine power and, under some conditions, ve-
hicle speed will decrease. Vehicle speed can be
controlled with the accelerator pedal, but the
vehicle may not accelerate at the desired
speed. The transmission will downshift or up-
shift as it reaches prescribed shift points. You
can also shift manually.
As driving conditions change and engine cool-
ant temperature is reduced, vehicle speed can
be increased using the accelerator pedal, and
air conditioning cooling function will automati-
cally be turned back ON. If:1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant tem-
perature gauge does not return to the
normal range from the H position, this
may indicate a malfunction. Move the
vehicle off the road to a safe area and
allow the engine to cool. If after checking
the oil and coolant, the
remains on
or engine coolant temperature does not
return to the normal range, do not con-
tinue to drive and contact an INFINITI
retailer.
The Malfunction Indicator Light (MIL)may also come ON. You do not need to have
your vehicle towed, unless it remains on, but
have it inspected soon by an INFINITI retailer.
See “WARNING/INDICATOR LIGHTS AND AU-
DIBLE REMINDERS” in the “2. Instruments and
controls” section.
