ence received, including interference
that may cause undesired operation.
FCC Warning
Changes or modification not expressly ap-
proved by the party responsible for com-
pliance could void the user’s authority to
operate the equipment.
For Canada:
This device complies with Industry Canada
licence-exempt RSS standard(s). Operation

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy
of your new vehicle.
Failure to follow these recommendations
may result in shortened engine life and
reduced engine performance.
. Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
. Do not accelerate at full throttle in any
gear.
. Avoid quick starts.
. Avoid hard braking as much as possible. Follow 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 andbrake application whenever possible.
.Maintain constant speed while com-muting 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 mini-mize 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 moreefficient to open windows to cool the
vehicle due to reduced engine load.
.Above 40 MPH (64 km/h), it is moreefficient to use A/C to cool the
vehicle due to increased aerodynamic
drag.
.Recirculating the cool air in the cabinwhen the A/C is on reduces cooling
load.

6-2In case of emergency
SIC2574
Push the switch on to warn other drivers
when you must stop or park under emer-
gency conditions. All turn signal lights will
flash.
WARNING
.If stopping for an emergency, be sure
to move the vehicle well off the road.
. Do not use the hazard warning
flashers while moving on the highway
unless unusual circumstances force
you to drive so slowly that your
vehicle might become a hazard to
other traffic. .
Turn signals do not work when the
hazard warning flasher lights are on.
The flasher can be actuated with the ignition
switch in any position.
When an impact that could activate the
supplemental air bags is detected, the
hazard warning flasher lights blink automa-
tically. If the hazard warning flasher switch is
pushed, the hazard warning flashers will turn
off.
WARNING
Do not turn the hazard warning flasher
switch to off until you can make sure
that it is safe to do so. Also, the hazard
flasher warning may not blink automa-
tically depending on the force of impact.
Some state laws may prohibit the use of the
hazard warning flasher switch while driving. In the event of a roadside emergency,
Roadside Assistance Service is available to
you. Please refer to your Warranty Informa-
tion Booklet (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada) for
details.
HAZARD WARNING FLASHER SWITCHROADSIDE ASSISTANCE PROGRAM

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds. If you have a flat tire, follow the instructions
in this section.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit and the “Tire Pressure Low - Add
Air” warning appears in the vehicle informa-
tion display, one or more of your tires is
significantly under-inflated. If the vehicle is
being driven with low tire pressure, the
TPMS will activate and warn you of it by
the low tire pressure warning light. This
system will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h).
For more details, see “Warning lights, in-
dicator lights and audible reminders” (P.2-
10) and “Tire Pressure Monitoring System
(TPMS)” (P.5-5).
WARNING
.
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use. .
If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat. If you have a flat tire,
replace it with a spare tire (if so
equipped).
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It

9-4Maintenance and schedules
Warning lights and chimes:Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient 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*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe condition 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 electro-
nic accessories 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.
Engine coolant level*: Check the coolant
level when the engine is cold.
Intercooler coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: 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.
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 inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4).)
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 evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check
the level when the fluid is cold, with the
engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form 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 accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
