CAUTION
. For cleaning, use a soft cloth, dam-
pened 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.

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (RPM).Do not rev
the engine into the red zone
.
The scale length and the red zone vary with
the engine model.
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.
JVI0639X
ENGINE COOLANT TEMPERA-
TURE 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
shown in the illustration.
The engine coolant temperature varies with
the outside air temperature and driving
conditions.
CAUTION
If the gauge indicates the engine coolant
temperature is near the hot (H) end of
the normal range, reduce vehicle speed
to decrease the temperature. If the
gauge is over the normal range, stop
the vehicle as soon as safely possible and
let the engine idle. If the engine is
overheated, continued operation of the
vehicle may seriously damage the engine.
See “If your vehicle overheats” (P.6-16)
for immediate action required.

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions in-
terfere with the Intelligent Key operation,
start the engine according to the following
procedure:
1. Move the shift lever to the P (Park)position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime
will sound.)
4. Push the ignition switch while depressing the brake pedal within 10 seconds after
the chime sounds. The engine will start.
After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears in the vehicle information
display even if the Intelligent Key is
inside the vehicle. This is not a malfunc-
tion. To turn off the Intelligent Key
battery discharge indicator, touch the
ignition switch with the Intelligent Key
again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery as
soon as possible. (See “Intelligent Key
battery replacement” (P.8-26).) .
Make sure the area around the vehicle is
clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window washer
fluid as frequently as possible, or at least
whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
. Lock all doors.
. Position seat and adjust head restraints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passengers
to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to the
ON position. (See “Warning lights, in-
dicator lights and audible reminders”
(P.2-10).)

mPRECAUTIONS ON CRUISE
CONTROL
.If the cruise control system malfunctions,
it will cancel automatically. The cruise
indicator (green) in the vehicle informa-
tion display will then blink to warn the
driver.
. If the engine coolant temperature be-
comes excessively high, the cruise con-
trol system will be canceled
automatically.
. If the cruise indicator (green) blinks, turn
the cruise control MAIN switch off and
have the system checked. It is recom-
mended you visit an INFINITI retailer for
this service.
. The cruise indicator (green) may some-
times blink when the cruise control MAIN
switch is turned ON while pushing the
SET/COAST (-), RESUME/ACCELER-
ATE (+) 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.
Starting and driving5-71
CRUISE CONTROL (if so equipped)

The Idling Stop System activates to prevent
unnecessary fuel consumption, exhaust
emissions and noise.
.When you fully depress the brake pedal
to stop the vehicle, the engine is turned
off automatically.
. When you release the brake pedal to
begin moving again, the engine is turned
on automatically.
WARNING
The engine restarts if the vehicle moves
at approximately 1 MPH (2 km/h) or
more (on a downhill grade, etc.), while
the engine is turned off by the Idling
Stop System. Depress the brake pedal
immediately to stop the vehicle to pre-
vent an accident.
CAUTION
At the end of the journey the engine
must be stopped and ignition switch be
turned off. Lock the vehicle as normal.
Turning the ignition switch OFF will shut
down all electrical systems. Failure to do
this may result in a discharged battery. NOTE:
The Idling Stop System will not activate
under the following conditions:
.
when the engine is kept idling without
the vehicle being driven after the engine
is turned on.
. when the engine coolant temperature is
low.
. when the battery capacity is low.
. when the battery temperature is low or
extremely high.
. when the vehicle is moving.
. when a negative pressure booster de-
creases.
. when the engine hood is opened with the
engine running.
. when the engine is turned on with the
engine hood open.
. when the driver’s seat belt is not fas-
tened.
. when the driver’s door is open.
. when the steering wheel is operated.
. when the angle of steering wheel is not
straight.
. when the Idling Stop System indicator
blinks at a low speed.
. when the fan speed control is in any
position other than “OFF” (0) while the
air flow control is in the front defroster
position. .
when the front defroster switch is on.
. when the rear window defroster switch
is on.
. When the temperature inside the vehicle
is lower than approximately 68°F
(20°C).
. When the temperature inside the vehicle
is higher than approximately 86°F
(30°C). (When the air conditioner is
off, the Idling Stop System will operate.)
. When the fan speed of the air condi-
tioner is set to the maximum speed.
. when the Idling Stop OFF switch is
turned on.
. when the power consumption is large.
. when the vehicle is traveling at altitudes
higher than 8,203 ft (2,500 m).
. when the accelerator pedal is depressed.
. when the shift lever is in the R (Reverse)
position.
. when the brake pedal is not firmly
depressed.
. when stopping the vehicle on steep
sloping roads.
NOTE:
The engine will not restart even if the brake
pedal is released while the Idling Stop
System is activated when the shift lever is
in the P (Park) position.
