WARNING
Never remove the key or turn the ignition
switch to the OFF position while driving.
The steering wheel will lock and could
cause the driver to lose control of the ve-
hicle. This could result in serious vehicle
damage or personal injury.
CAUTION
Use electrical accessories with the engine
running to avoid discharging the vehicle
battery. If you must use accessories while
the engine is not running, do not use them
for extended periods of time and do not use
multiple electrical accessories at the same
time.
The switch includes an anti-theft steering
lock device.
STEERING LOCK

NPA1483
IGNITION SWITCH
Starting and driving5-15

At the end of a journey turn the ignition OFF
to avoid a discharged battery. The Idle
Stop/Start System does not automatically
turn ignition off.Vehicles with Intelligent Key are equipped
with keys featuring an integrated Intelligent
Key function and in some cases a detachable
push-button ignition switch (Start/Stop but-
ton).
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the ve-
hicle. This occurs, for example, when starting
the engine.
When you insert the push-button ignition
switch into the ignition lock, the system
needs approximately two seconds recogni-
tion time. You can then use the push-button
ignition switch.
WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop when
the ignition switch is pressed 3 consecutive
times in quick succession or the ignition
switch is pushed and held for more than 2
seconds.) If the engine stops while the ve-
hicle is being driven, this could lead to a
crash and serious injury.
Before operating the push-button ignition
switch:
•Select P (Park). Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. Prerequisite
for this is that:
•You do not depress the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
To start the vehicle without actively using the
key:
•The push-button ignition switch must be
inserted in the ignition lock.
•The key must be in the vehicle.
•The vehicle must not be locked with the
key or Intelligent Key (see "Keys" in the "3.
Pre-driving checks and adjustments" sec-
tion).
Do not keep the Intelligent Key:
•With electronic devices, for example a mo-
bile phone or another key.
•With metallic objects, for example coins or
metal film.
•Inside metallic objects, for example a metal
case.
This can affect the functionality of the Intel-
ligent Key.

3. Turn the key to the START position3in
the ignition lock and release it as soon as
the engine is running.
If the engine is very hard to start because it is
flooded, depress the accelerator pedal all the
way to the floor and hold it. Turn the ignition
switch to the START position to start crank-
ing the engine. After 5 or 6 seconds, stop
cranking by turning the ignition switch to
OFF. After cranking the engine, release the
accelerator pedal. Crank the engine with your
foot off the accelerator pedal by depressing
the brake pedal and turning the ignition
switch to start the engine. If the engine starts,
but fails to run, repeat the above procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does not
start, turn the ignition key to the OFF po-
sition and wait 10 seconds before cranking
again, otherwise the starter could be
damaged. 4.
Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the
engine while warming it up. Drive at mod-
erate speed for a short distance first, es-
pecially in cold weather. In cold weather,
keep the engine running for a minimum of
2 - 3 minutes before shutting it off. Start-
ing and stopping the engine over a short
period of time may make the vehicle more
difficult to start.
5. To stop the engine, Shift the transmission to position P (Park) by pressing the

button. and turn the ignition switch to the
OFF position.
NOTE
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
•Installation or extended use of electronic
accessories that consume battery power
when the engine is not running (Phone
chargers, GPS, DVD players, etc.)
•Vehicle is not driven regularly and/or only
driven short distances. In these cases, the
battery may need to be charged to main-
tain battery health.
STARTING PROCEDURE USING
THE PUSH-BUTTON IGNITION
SWITCH (IF EQUIPPED)
The push-button ignition switch can be used
to start the vehicle manually without insert-
ing the key into the ignition lock. The key must
be in the vehicle and the start/stop button
must be inserted in the ignition lock (see "Re-
moving the start/stop button" earlier in this
section). This mode for starting the engine
operates independently of the ECO start/
stop automatic engine start function.
You can start the engine if a valid key is in the
vehicle. Switch off the engine and always
take the key with you when leaving the ve-
hicle, even if you only leave it for a short time.
Pay attention to the important safety notes.
•Depress the brake pedal and keep it de-
pressed.
•Press the push button ignition switch once
(see " Push-button ignition switch (if
equipped)" earlier in this section). The en-
gine starts.

activated each time you start the engine with
the ignition key.
If the Idle Stop/Start function has been
manually deactivated (see "Deactivating/
activating the Idle Stop/Start function" later
in this section) or a malfunction has caused
the system to be deactivated, the
Idle
Stop/Start symbol is not displayed.

You can obtain information about trickle
chargers from an INFINITI retailer. The electric power steering system is de-
signed to reduce the driver effort required to
steer the vehicle.

following message will be displayed in the
vehicle information display along with an
audible warning tone.
[Power Steering Malfunction See Opera-
tors Manual]

assistance will no longer be provided by the
system.
The effort required to steer the vehicle will
increase. This will be most noticeable at
low speed and when performing a tight
turning maneuver.
Check whether you are able to provide the
extra effort required.
If you are able to steer safely: Carefully
drive on to an INFINITI retailer.
If you are unable to steer safely: Do NOT
drive on. It is recommended you contact
the nearest INFINITI retailer for
assistance.

If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are ex-
tremely deteriorated, the power steer-
ing system may not operate properly
and the [Power Steering Malfunction
See Operators Manual] warning may
