2017 INFINITI QX30 battery replacement

The Intelligent Key system can operate all the
door locks using the remote control function or
touching the request switch on the vehicle
without taking the key out from a pocket or
purse. The operating environment and/or con-
ditions may affect the Intelligent Key system
operation.
Be sure to read the following before using the
Intelligent Key system.
CAUTION
•Be sure to carry the Intelligent Key with you
when operating the vehicle.
•Never leave the Intelligent Key in the ve-
hicle 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
station.
•When in possession of wireless equipment,
such as a cellular telephone, transceiver or a
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 two years. If the battery is
discharged, replace it with a new one.
When the Intelligent Key battery is low, an
indicator illuminates in the vehicle information
display. For additional information, refer to
Safety systemsin the2. Instruments and
controlssection.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 additional information, refer toIntelligent
key battery replacementin the
8. Do-it-yourselfsection.
As many as four Intelligent Keys can be regis-
tered and used with one vehicle. For informa-
tion about the purchase and use of additional
Intelligent Keys, it is recommended that you
visit an INFINITI retailer.
CAUTION
Listed below are conditions or occurrences
which will damage the Intelligent Key:
•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.
3-8Pre-driving checks and adjustments

CAUTION
•Always connect positive+to positive+and negative-to body ground (for ex-
ample, strut mounting bolt, engine lift
bracket, etc.) – not to the battery’s negative
-.
•Be sure that the jumper cables do not touch
moving parts in the engine compartment
and that the cable clamps do not contact
any other metal.
9. Start the engine of the other vehicle
Aand
let it run for a few minutes. Keep the engine
speed at about 2,000 rpm.
10. Start the engine of your vehicle
Bin the
normal way.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does not
start right away, place the ignition switch in
the OFF position and wait 10 seconds before
trying again.11. After starting the engine of your vehicle,
carefully disconnect the negative lead and
then the positive lead (
4→3→2→
1).
12. Remove and dispose of the cloth that was
used to cover the ventilator holes as it may
be contaminated with corrosive acid.
13. Install the ventilator caps (if equipped).
14. Close the hood.
NOTE
For models which incorporate the Idle Stop/
Start System:
•Ensure that the battery fitted is the special
battery that is enhanced with regard to the
charge-discharge capacity and life perfor-
mance. Avoid using any other battery for the
Idle Stop/Start System, as this may cause
early deterioration of the battery or a mal-
function of the Idle Stop/Start System. It is
recommended that a Genuine INFINITI bat-
tery is fitted. For more information, it is
recommended you contact an INFINITI re-
tailer.
•If the battery terminal is disconnected (for
battery replacement, etc.) and then recon-
nected, there may be some delay before the
Idle top/Start System reactivates.Do not attempt to start the engine by pushing
the vehicle.
CAUTION
•Automatic Transmission (AT) model cannot
be push-started or tow-started. Attempting
to do so may cause damage to the transmis-
sion.
•Three-way catalyst equipped models
should not be started by pushing. Attempt-
ing to do so may cause damage to the three-
way catalyst.
•Never try to start the vehicle by towing it;
when the engine starts, the forward surge
could cause the vehicle to collide with the
tow vehicle.
