3-14Pre-driving checks and adjustments

The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated payment device on
the key ring. Restart the engine using the
following procedures:
1. Leave the ignition switch in the ON posi-
tion for approximately 5 seconds.
2. Turn the ignition switch to the OFF or
LOCK position and wait approximately
5 seconds.
3. Repeat Step 1 and 2 again.
4. Restart the engine while holding the de-
vice (which may have caused the interfer-
ence) separate from the registered key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices.

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.

START3
The engine starter activates and the engine
will start. As soon as the engine has started,
release the key immediately. It will return to
the ON position.
NOTE
For vehicles fitted with Idle Stop/Start Sys-
tem:
When the engine is automatically stopped
by the Idle Stop/Start System the ignition
switch can still be operated as usual.
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 button).
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 recognition 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").
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.

The Idle Stop/Start function switches the
engine off automatically if the vehicle is
stopped under certain conditions.
When pulling away again, the engine starts
automatically. The Idle Stop/Start function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.

and you exit the vehicle, the engine is re-
started automatically. The vehicle may be-
gin moving There is a risk of accident and
injury.
If you wish to exit the vehicle, always turn
off the ignition and secure the vehicle
against rolling away.If the
Idle Stop/Start symbol is shown
in green in the vehicle information display,
the Idle Stop/Start function switches the
engine off automatically once the vehicle
stops moving.
The Idle Stop/Start function is automatically
activated each time you start the engine with
the ignition key.
If the Idle Stop/Start function has been manu-
ally deactivated (see"Deactivating/activating
the Idle Stop/Start function" later in this sec-
tion) or a malfunction has caused the system
to be deactivated, the
Idle Stop/Start
symbol is not displayed.
AUTOMATIC ENGINE
SWITCH-OFF
The Idle Stop/Start function is operational
and theIdle Stop/Start symbol is dis-
played in green in the vehicle information dis-
play, if:
•The indicator light in the ECO button is lit
green.
•The outside temperature is within the
range that is suitable for the system.
•The engine is at normal operating tem-
perature.

Visit an INFINITI retailer and seek advice
NOTE
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.
WARNING
If during operation a fault is detected the
following message will be displayed in the
vehicle information display along with an
audible warning tone.
[Power Steering Malfunction See Opera-
tors Manual]
In conjunction with this warning, steering
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.
CAUTION
•If wheels or tires other than INFINITI
recommended ones are used, the power
steering system may not operate prop-
erly and the [Power Steering Malfunc-
tion See Operators Manual] warning
may appear in the vehicle information
display.
•Do not modify the vehicle's suspension.
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
appear in the vehicle information dis-
play.
•Do not modify the vehicle's steering. If
steering parts are not INFINITI recom-
mended for your vehicle or are ex-
tremely deteriorated, the power steer-
ing system may not operate properly

•After a short time, hill start assist will no
longer brake your vehicle and it could
roll away There is a risk of an accident
and injury. Therefore, quickly move your
foot from the brake pedal to the accel-
erator pedal. Never leave the vehicle
when it is held by hill start assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake
pedal. This gives you enough time to move
your foot from the brake pedal to the accel-
erator pedal and depress it before the vehicle
begins to roll.
Hill start assist is not active if
•You are pulling away on a level road or a
downhill gradient.
•On vehicles with automatic transmission,
the transmission is in position N.
•The electric parking brake is applied.
•VDC is malfunctioning.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, see
"Engine cooling system".
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
"Battery" of this manual.
DRAINING OF ENGINE COOLANT
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see "Changing engine
coolant" of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
an INFINITI retailer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial laws before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
