The Idle Stop/Start function switches the en-
gine 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 consump-
tion and emissions of your vehicle.
WARNING
If the engine is switched off automatically and
you exit the vehicle, the engine is restarted
automatically. The vehicle may begin 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 roll-
ing 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 (seeDeactivating/activating
the Idle Stop/Start functionlater in this sec-
tion) or a malfunction has caused the system to
be deactivated, the
Idle Stop/Start sym-
bol is not displayed.
AUTOMATIC ENGINE SWITCH-OFF
The Idle Stop/Start function is operational and
theIdle Stop/Start symbol is displayed
in green in the vehicle information display, if:
•The indicator lamp 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 tempera-
ture.
•The set temperature for the vehicle interior
has been reached.
•The battery is sufficiently charged.
•The system detects that the windshield is
not misted up when the air-conditioning sys-
tem is switched on.
•The hood is closed.
•The driver’s door is closed and the driver’s
seat belt is fastened.
If the conditions for automatic engine switch-off
are not all fulfilled, the
Idle Stop/Start
symbol is shown in yellow.

CAUTION
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of
this teach-in process.
Brake pads/linings and rotors that are either
new or have been replaced only achieve opti-
mum braking effect after several hundred
miles of driving. Compensate for the reduced
braking effect by applying greater force to the
brake pedalFollow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.
1.Use Smooth Accelerator and Brake Pedal
Application
•Avoid rapid starts and stops.
•Use smooth, gentle accelerator and brake
application whenever possible.
•Maintain constant speed while commut-
ing and coast whenever possible.
2.Maintain Constant Speed
•Look ahead to try and anticipate and
minimize stops.
•Synchronizing your speed with traffic lights
allows you to reduce your number of stops.
•Maintaining a steady speed can minimize
red light stops and improve fuel efficiency.
3.Use Air Conditioning (A/C) at Higher Vehicle
Speeds
•Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load.
•Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle due
to increased aerodynamic drag.
•Recirculating the cool air in the cabin
when the A/C is on reduces cooling load.
4.Drive at Economical Speeds and Distances
•Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where legally
allowed) can improve fuel efficiency due
to reduced aerodynamic drag.
•Maintaining a safe following distance
behind other vehicles reduces unneces-
sary braking.
•Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
•Select a gear range suitable to road
conditions.
5.Use Cruise Control
•Using cruise control during highway driv-
ing helps maintain a steady speed.
•Cruise control is particularly effective in
providing fuel savings when driving on
flat terrains.
Utilize a map or navigation system to determine
the best route to save time.
FUEL EFFICIENT DRIVING TIPS
5-82Starting and driving

6.Avoid Idling
•Shutting off your engine when safe for
stops exceeding 30 seconds saves fuel
and reduces emissions.
7.Buy an Automated Pass for Toll Roads
•Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
8.Winter Warm Up
•Limit idling time to minimize impact to
fuel economy.
•Vehicles typically need no more than 30
seconds of idling at start-up to effectively
circulate the engine oil before driving.
•Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
9.Keeping your Vehicle Cool
•Park your vehicle in a covered parking
area or in the shade whenever possible.
•When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system.
•Keep your engine tuned up.
•Follow the recommended scheduled mainte-
nance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
•Use the recommended viscosity engine oil.
For additional information, seeRecom-
mended fluids/lubricants and capacitiesin
the10. Technical informationsection
WARNING
•Do not drive beyond the performance capa-
bility of the tires, even with 4WD engaged.
Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause loss
of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
•For 4WD equipped vehicles, do not attempt to
raise two wheels off the ground and shift the
transmission to any drive or reverse position
with the engine running. Doing so may result
in drivetrain damage or unexpected vehicle
movement which could result in serious ve-
hicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
even if the other two wheels are raised off
the ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with 4WD before it is placed on a
INCREASING FUEL ECONOMY FOUR-WHEEL DRIVE (4WD) (IF EQUIPPED)
Starting and driving5-83

When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
slight pulsation. This is normal and indicates
that the Brake Assist System is operating (if
equipped).
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out
the brake linings/pads faster, and increase fuel
consumption.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or acceleration could cause the
wheels to skid and result in an accident.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.To dry the brakes, drive the vehicle at a safe
speed while lightly depressing the brake pedal
to heat up the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.
Driving uphill
When starting on a steep gradient, it is some-
times difficult to operate the brake. Use the
parking brake to hold the vehicle. When ready
to start, make sure that the shift lever is in an
appropriate forward or reverse driving position,
release the parking brake while depressing the
accelerator pedal. If your vehicle has an electric
parking brake, this will automatically release
when you depress the accelerator pedal (DCT
models).
Driving downhill
The engine braking action is effective for con-
trolling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine braking,
should be selected.
Parking brake break-in
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
The Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent acci-
dents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on normal
surfaces even with ABS. Stopping distances
may also be longer on rough, gravel or snow
covered roads, or if you are using tire chains.
Always maintain a safe distance from the ve-
hicle in front of you. Ultimately, the driver is
responsible for safety.

MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:
•The accumulation of moisture-retaining dirt
and debris in body panel sections, cavities,
and other areas.
•Damage to the paint surface and other
protective coatings caused by gravel and
stone chips or minor traffic accidents.
ENVIRONMENTAL FACTORS INFLUENCE
THE RATE OF CORROSION
Moisture
The accumulation of sand, dirt and water on the
inside floor of the vehicle can accelerate corro-
sion. Wet floor carpet/floor mats will not dry
completely inside the vehicle. They should be
removed and completely dried to avoid floor
panel corrosion.
Relative humidity
Corrosion will be accelerated in areas of high
relative humidity, especially those areas where
the temperatures stay above freezing and
where atmospheric pollution exists and road
salt is used.
Temperature
High temperatures accelerate the rate of corro-
sion to those parts which are not well venti-
lated.
Air pollution
Industrial pollution, the presence of salt in the
air in coastal areas, or heavy road salt use
accelerates the corrosion process. Road salt
also accelerates the disintegration of paint sur-
faces.
TO PROTECT YOUR VEHICLE FROM
CORROSION
•Wash and wax your vehicle often to keep the
vehicle clean.
•Always check for minor damage to the paint
surface and repair it as soon as possible.
•Keep drain holes in the lower edge of the
doors open to avoid water accumulation.
•Check the underbody for accumulation of
sand, dirt or salt. If present, wash with water
as soon as possible.
CAUTION
•NEVER remove dirt, sand or other debris
from the passenger compartment by wash-
ing it out with a hose. Remove dirt with a
vacuum cleaner or broom.
•Never allow water or other liquids to come
in contact with electronic components in-
side the vehicle as this may damage them.
Chemicals used for road surface deicing are
extremely corrosive. They accelerate corrosion
and deterioration of underbody components
such as the exhaust system, fuel and brake
lines, brake cables, floor pan and fenders.
In winter, the underbody must be cleaned peri-
odically.
For additional protection against rust and cor-
rosion, which may be required in some areas, it
is recommended that you visit an INFINITI re-
tailer.
CORROSION PROTECTION
Appearance and care7-7

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from moving.
Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the en-
gine is hot. Always turn off the engine and
wait until it cools down.
•If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts.
•It is advisable to secure or remove any loose
clothing and any jewelry, such as rings,
watches, etc. before working on your ve-
hicle.
•If you must run the engine in an enclosedspace such as a garage, be sure there is
proper ventilation for exhaust gases to es-
cape.
•Never get under the vehicle while it is sup-
ported by a jack.
•Keep smoking materials, flame and sparks
away from fuel and the battery.
•Never connect or disconnect either the bat-
tery or any transistorized component con-
nector while the ignition switch is in the ON
position.
•On gasoline engine models with the Multi-
port Fuel Injection system, the fuel filter and
fuel lines should be serviced by an INFINITI
retailer or qualified workshop because the
fuel lines are under high pressure even
when the engine is turned off.
•Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
switch is in the OFF position and the engine
is not running. To avoid injury, always dis-
connect the negative battery cable before
working near the fan.
•Always wear eye protection whenever you
work on your vehicle.
•Never leave the engine or the transmission
related component harness connector dis-
connected while the ignition switch is in the
ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle flu-
ids can hurt the environment. Always con-
form to local regulations for disposal of ve-
hicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage.If in doubt about any
servicing, it is recommended you have it done by
an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

Replace the spark plugs according to the main-
tenance schedule shown in a separate mainte-
nance booklet.
If replacement is required, it is recommended
that you visit an INFINITI retailer.
Always replace spark plugs with recommended
or equivalent ones.
WARNING
Be sure the engine and ignition switch are off
and that the parking brake is engaged
securely.
CAUTION
•Be sure to use the correct socket to remove
the spark plugs. An incorrect socket can
cause damage to the spark plugs.It is recommended that you visit an INFINITI
retailer if checking or replacement is required.
WARNING
•Operating the engine with the air cleaner
filter off can cause you or others to be
burned. The air cleaner filter not only cleans
the intake air, it also stops the flame if the
engine backfires. If the air cleaner is not
installed and the engine backfires, you
could be burned. Never drive with the air
cleaner filter off. Be cautious working on the
engine when the air cleaner is off.
•Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result in
serious injury.
CLEANING
If the windshield or rear window is not clear
after using the window washer or if a wiper
blade chatters when running, wax or other
material may be on the blade or windshield.
Clean the outside of the windshield or rear
window with a washer solution or a mild deter-
gent. The windshield or rear window is clean if
beads do not form when rinsing with clear
water.
Clean the blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Then
rinse the blade with clear water. If the wind-
shield or rear window is still not clear after
cleaning the blades and using the wiper, re-
place the blades.
CAUTION
Worn windshield wiper blades can damage the
windshield and impair driver vision.

:
Check that the air comes out of the defroster
outlets properly and in good quantity when
operating the heater or air conditioner.
Windshield wiper and washer*
:
Check that the wipers and washer operate
properly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*
:
Except for maintenance free battery, check the
fluid level in each cell. It should be between the
“UPPER” and “LOWER” lines. Vehicles operated
in high temperatures or under severe condi-
tions require frequent checks of the battery
fluid level.NOTE
Care should be taken to avoid situations that can
lead to potential battery discharge and potential
no-start conditions such as:
1. Installation or extended use of electronic ac-
cessories that consume battery power when
the engine is not running (Phone chargers,
GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or only
driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*
:
Make sure that the brake fluid level is between
the “MAX” and “MIN” lines on the reservoir.
Coolant level*
:
Check the coolant level when the engine is cold.
Engine drive belt(s)*
:
Make sure that no belt is frayed, worn, cracked
or oily.
Engine oil level*
:
Check the level after parking the vehicle on a
level spot and turning off the engine. Wait more
than 15 minutes for the oil to drain back into the
oil pan.
9-4Maintenance and Schedules

Exhaust system:
Make sure there are no loose supports, cracks
or holes. If the sound of the exhaust seems
unusual or there is a smell of exhaust fumes,
immediately have the exhaust system in-
spected. It is recommended you visit an INFINITI
retailer for this service. SeePrecautions when
starting and drivingin the5. Starting and
drivingsection.
Fluid leaks
:
Check under the vehicle for fuel, oil, water or
other fluid leaks after the vehicle has been
parked for a while. Water dripping from the air
conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evi-
dent, check for the cause and have it corrected
immediately.
Radiator and hoses
:
Check the front of the radiator and clean off any
dirt, insects, leaves, etc., that may have accu-
mulated. Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody
:
The underbody is frequently exposed to corro-
sive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust willform on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, seeCleaning
exteriorin the7. Appearance and caresec-
tion.
Windshield washer fluid*
:
Check that there is adequate fluid in the reser-
voir.The following descriptions are provided to give
you a better understanding of the scheduled
maintenance items that should be regularly
checked or replaced. The maintenance schedule
indicates at which mileage/time intervals each
item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer to
General maintenancein this section.
Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You are
not required to perform maintenance on these
items in order to maintain the warranties which
come with your vehicle. Other maintenance
items and intervals are required.
When applicable, additional information can be
found in the “Do-it-yourself” section in Chapter
8.
NOTE
INFINITI does not advocate the use of non-OEM
approved aftermarket flushing systems and
strongly advises against performing these ser-
vices on an INFINITI product. Many of the after-
market flushing systems use non-OEM approved
chemicals or solvents, the use of which has not
been validated by INFINITI.
