●Your brake system may not be working prop-
erly if the warning light is on. Driving could
be dangerous. If you judge it to be safe, drive
carefully to the nearest service station for
repairs. Otherwise, have your vehicle towed
because driving it could be dangerous.
● Pressing the brake pedal with the engine
stopped and/or low brake fluid level may
increase your stopping distance and braking
will require greater pedal effort as well as
pedal travel. ●
If the brake fluid level is below the minimum
or MIN mark on the brake fluid reservoir, do
not drive until the brake system has been
checked at an INFINITI retailer.

●Never leave the Intelligent Key in the vehicle
when you leave the vehicle.
The Intelligent Key is always communicating
with the vehicle as it receives radio waves. The
Intelligent Key system transmits 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 sta-
tion.
● When in possession of wireless equipment,
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 personal com-
puter.
● When the vehicle is parked near a parking
meter. In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depend-
ing on the operating conditions, the battery’s
life is approximately 2 years. If the battery is
discharged, replace it with a new one.
Since the Intelligent Key is continuously receiv-
ing radio waves, if the key is left near equip-
ment 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 bat-
tery, see “INTELLIGENT KEY BATTERY REPLACE-
MENT” in the “8. Maintenance and do-it-
yourself” section.
For models with a steering wheel lock mecha-
nism: Because the steering wheel is locked
electrically, unlocking the steering wheel with
the ignition switch in the LOCK position is
impossible when the vehicle battery is com-
pletely discharged. Pay special attention that
the vehicle battery is not completely dis-
charged.
As many as 4 Intelligent Keys can be registered
and used with one vehicle. For information
about the purchase and use of additional Intel-
ligent Keys, contact an INFINITI retailer.CAUTION
●
Do not allow the Intelligent Key, which con-
tains 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, immediately
wipe until it is completely dry.
● Do not place the Intelligent Key for an ex-
tended period in an area where tempera-
tures exceed 140°F (60°C).
● Do not attach the Intelligent Key with a key
holder that contains a magnet.
● Do not place the Intelligent Key near equip-
ment that produces a magnetic field, such as
a TV, audio equipment and personal
computers.
