CAUTION
.
For cleaning, use a soft cloth, dampened
with water. Never use a rough cloth,
alcohol, benzine, thinner or any kind of
solvent or paper towel with a chemical
cleaning agent. They will scratch or
cause discoloration to the lens.
. Do not spray any liquid such as water on
the meter lens. Spraying liquid may
cause the system to malfunction.

SIC4371
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.
SIC4372
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” in the“6. In case of
emergency” section for immediate action
required.

when the rear air conditioner screen is
shown on the front display. To activate
the rear control buttons, push the
“REAR” button on the front air condi-
tioner control panel and switch the
screen on the front display.

OPERATING TIPS
When the engine coolant temperature and
outside air temperature are low, the air
flow from the foot outlets may not operate.
However, this is not a malfunction. After
the coolant temperature warms up, the air
flow from the foot outlets will operate
normally.
The sensors
*Aand*Blocated on the
instrument panel help maintain a constant
temperature. Do not put anything on or
around the sensors.
LINKING INTELLIGENT KEY
The Climate control system settings can be
memorized for each Intelligent Key. For
more details, see “Setting memory func-
tion” in the “3. Pre-driving checks and
adjustments” section.
IN-CABIN MICROFILTER
Models without Advanced Climate Control
System:
The climate control system is equipped
with an in-cabin microfilter which collects
dirt, pollen, dust, etc.

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 temperature 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,
vehicle 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 upshift as it reaches pre-
scribed shift points. You can also shift
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator pedal, and air conditioning cooling function will automatically 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
temperature 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 tempera-
ture does not return to the normal
range, do not continue 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 audible reminders” in the“2.
Instruments and controls” section.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced speed
may be lower than other traffic, which could
increase the chance of a collision. Be
especially careful when driving. If the
vehicle cannot maintain a safe driving
speed, pull to the side of the road in a safe
area. Allow the engine to cool and return to
normal operation. See“If your vehicle over-
heats” in the“6. In case of emergency”
section.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not covered
by warranty. Turn off the engine as soon as
it is safe to do so.
DRIVING THE VEHICLE

5-54Starting and driving
unauthorized modifications to this equip-
ment. Such modifications could void the
user’s authority to operate the equipment.PRECAUTIONS ON CRUISE CONTROL
.If the cruise control system malfunc-
tions, it will cancel automatically. The
CRUISE indicator light on the meter
panel will then blink to warn the driver.
. If the engine coolant temperature be-
comes excessively high, the cruise
control system will be canceled auto-
matically.
. If the CRUISE indicator light blinks, turn
the cruise control main switch off and
have the system checked by your
INFINITI retailer.
. The CRUISE indicator light may some-
times blink when the cruise control
main switch is turned ON while pushing
the ACCELERATE/RESUME, COAST/SET
or CANCEL switch. To properly set the
cruise control system, perform the
steps below in the order indicated.
WARNING
Do not use the cruise control when driving
under the following conditions:
. when it is not possible to keep the
vehicle at a set speed .
in heavy traffic or in traffic that varies in
speed
. on winding or hilly roads
. on slippery roads (rain, snow, ice, etc.)
. in very windy areas
Doing so could cause a loss of vehicle
control and result in an accident.
CRUISE CONTROL (if so equipped)

The VDC off indicator lightwill
illuminate.
Push the VDC OFF switch again or restart
the engine to turn ON the system.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” in the
“8. Maintenance and do-it-yourself” sec-
tion.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”in
the “8. Maintenance and do-it-yourself”
section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” in the“8. Main-
tenance and do-it-yourself” section.
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire
type, size, speed rating and availability
information.
For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires.
