7. Intelligent Key battery discharge
indicator
This indicator appears when the Intelligent
Key battery is running out of power.
If this indicator appears, replace the
battery with a new one. (See “Intelligent
Key battery replacement” (P.8-25).)
8. Hybrid system start operation for
Intelligent Key system indicator
This indicator appears when the Intelligent
Key battery is running out of power and
when the Intelligent Key System and
vehicle are not communicating normally.
If this indicator appears, touch the ignition
switch with the Intelligent Key while
depressing the brake pedal. (See “Intelli-
gent Key battery discharge” (P.5-13).)
9. Key ID Incorrect warning
The warning appears when the ignition
switch is pushed from the LOCK position
and the Intelligent Key cannot be recog-
nized by the system. You cannot start the hybrid system with an unregistered key.
Use the registered Intelligent Key.
See
“Intelligent Key” (P.3-2).
10. Parking brake release warning
This warning appears when the vehicle
speed is above 4 MPH (7 km/h) and the
parking brake is applied.
11. Low fuel warning
This warning appears when the fuel level in
the tank is getting low. Refuel as soon as it
is convenient, preferably before the fuel
gauge reaches the empty (0) position.
There is a small reserve of fuel remaining
in the tank when the fuel gauge reaches
the empty (0) position.
12. Low washer fluid warning
This warning appears when the washer
tank fluid is at a low level. Add washer fluid
as necessary. (See “Window washer fluid”
(P.8-16).)
13. Door/trunk open warning
This warning appears if any of the doors
and/or the trunk lid are open or not closed
securely. The vehicle icon indicates which
door or the trunk lid is open on the display.
14. Intelligent Key system warning
This warning appears if there is a malfunc-
tion in the Intelligent Key system.
If this warning appears while the hybrid
system is stopped, the hybrid system
cannot be started. If this warning appears
while the hybrid system is running, the
vehicle can be driven. However, contact an
INFINITI retailer for repair as soon as
possible.
15. Loose Fuel Cap warning
This warning appears when the fuel-filler
cap is not tightened correctly after the
vehicle has been refueled. (See “Fuel-filler
cap ”(P.3-22).)
16. Tire Pressure Low - Add Air
warning
This warning appears when the low tire
pressure warning light in the meter illumi-
nates and low tire pressure is detected.
The warning appears each time the ignition
switch is placed in the ON position as long
as the low tire pressure warning light
remains illuminated. If this warning ap-
pears, stop the vehicle and adjust the
pressure to the recommended COLD tire
pressure shown on the Tire and Loading
Instruments and controls2-25

CAUTION
.Be sure to carry the Intelligent Key with
you when operating the vehicle.
. Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicat-
ing with the vehicle as it receives radio
waves. The Intelligent Key system trans-
mits weak radio waves. Environmental
conditions may interfere with the operation
of the Intelligent Key system under the
following operating conditions.
.When operating near a location where
strong radio waves are transmitted,
such as a TV tower, power station and
broadcasting station.
. When in possession of wireless equip-
ment, such as a cellular telephone,
transceiver, and CB radio.
. When the Intelligent Key is in contact
with or covered by metallic materials.
. When any type of radio wave remote
control is used nearby.
. When the Intelligent Key is placed near
an electric appliance such as a perso- nal computer.
. When the vehicle is parked near a
parking meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key
function or use the mechanical key.
Although the life of the battery varies
depending on the operating conditions,
the battery’s life is approximately 2 years.
If the battery is discharged, replace it with
a new one.
When the Intelligent Key battery is almost
discharged, see “Intelligent Key battery
discharge” (P.5-13) to start the hybrid
system.
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery repla-
cement” (P.8-25).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, contact an INFINITI retailer.
CAUTION
.
Do not allow the Intelligent Key, which
contains electrical components, to come
into contact with water or salt water.
This could affect the system function.
. Do not drop the Intelligent Key.
. Do not strike the Intelligent Key sharply
against another object.
. Do not change or modify the Intelligent
Key.
. Wetting may damage the Intelligent Key.
If the Intelligent Key gets wet, immedi-
ately wipe until it is completely dry.
. Do not place the Intelligent Key for an
extended period in an area where
temperatures exceed 1408F (608C).
. If the outside temperature is below 148F
(−108C), the battery of the Intelligent
Key may not function properly.
. Do not attach the Intelligent Key with a
key holder that contains a magnet.
. Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions
interfere with the Intelligent Key operation,
start the hybrid system 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 depres-
sing the brake pedal within 10 seconds
after the chime sounds. The hybrid
system will start.
After step 3 is performed, when the
ignition switch is pushed without depres-
sing 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 hybrid
system is started by the above proce-
dures, the Intelligent Key battery dis-
charge indicator appears in the vehicle
information display even if the Intelli-
gent Key is inside the vehicle. This is
not a malfunction. To turn off the
Intelligent Key battery discharge indi-
cator, 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.8-25).).
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 appear-
ance and condition. Also check tires for
proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to
the ON position. (See “Warning/indica-
tor lights and audible reminders” (P.2-
12).)
