check engine light INFINITI G-CONVERTIBLE 2011 Owner's Manual

●As there is a performance limit to the Pre-
view Function, never rely solely on this sys-
tem. This system does not correct careless
inattentive or absent-minded driving, or
overcome poor visibility in rain, fog, or other
bad weather. Reduce vehicle speed by de-
pressing the brake pedal, in order to main-
tain a safe distance between vehicles.
● The system may not detect the vehicle in
front of you in certain road or weather condi-
tions. The Preview Function may not operate
properly under the following conditions. The
vehicle is still driveable under normal condi-
tions and the Brake Assist will operate.
– When rain, snow or dirt adhere to the sys- tem sensor
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– Winding or hilly roads may cause the sen- sor to temporarily not detect a vehicle in
the same lane or may detect objects or
vehicles in other lanes.
– Vehicle position in the lane may cause the sensor to temporarily not detect a vehicle
in the same lane or may detect objects or
vehicles in other lanes. ●
When the Preview Function operates, the
brake pedal may move slightly and may
make a small noise. This is not a system
malfunction.
Warning light and display
When the Preview Function is not operating
properly, a chime sounds and the system warn-
ing light (orange) will come on.
Action to take :
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine and resume driving.
If the indicator stays on, it may indicate that the
Preview Function is malfunctioning (the brake is
operative). Although the Vehicle is still drive-
able under normal conditions, have the vehicle
checked at an INFINITI retailer.

and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h).
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, the VDC system helps to perform the
following functions.
●
Controls brake pressure to reduce wheel slip
on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).
● Controls brake pressure at individual wheels
and engine output to help the driver main-
tain control of the vehicle in the following
conditions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions).
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations. When the VDC system operates, the VDC warn-
ing light
in the instrument panel flashes
so note the following:
● The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
● You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
● Adjust your speed and driving to the road
conditions.
See “Vehicle Dynamic Control (VDC) warning
light” in the “2. Instruments and controls”
section.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instru-
ment panel. The VDC system automatically
turns off.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator
illuminates
to indicate the VDC system is off. When the VDC
switch is used to turn off the system, the VDC
system still operates to prevent one drive wheel
from slipping by transferring power to a non
slipping drive wheel. The VDC warning light
flashes if this occurs. All other VDC
functions are off, and the VDC warning light

(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
CHECK TIRE PRESSURE warning appears on the
dot matrix crystal display, one or more of your
tires is significantly under-inflated. If the ve-
hicle 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/INDICATOR LIGHTS AND
AUDIBLE REMINDERS” in the “2. Instruments
and controls” section and “TIRE PRESSURE
MONITORING SYSTEM (TPMS)” in the “5. Start-
ing and driving” section.

6-2In case of emergency

This vehicle does not have a spare tire. The
emergency tire puncture repair kit (Emergency
Tire Sealant) is supplied with the vehicle in-
stead of a spare tire. It can be used to tempo-
rarily repair minor tire punctures.
If possible, have the vehicle towed to a facility
that can repair or replace the flat tire. Using the
emergency tire puncture repair kit may cause a
malfunction of the tire pressure sensor and
cause the low tire pressure warning light to
illuminate.
If you have a flat tire, follow the instructions
below.
CAUTION
●To avoid the emergency tire puncture kit be-
ing damaged during storage or use:
– Only use the emergency tire puncture re- pair kit on your vehicle. Do not use it on
other vehicles.
– Only use the kit to inflate the tires of your vehicle and to check the vehicle’s tire
pressure.
– Only plug the compressor into a 12V DC car power point.
– Keep the kit free of water and dirt.
– Do not disassemble or modify the kit. – Do not drop the kit or allow hard impacts
to the kit.
● Do not use the emergency tire puncture re-
pair kit under the following conditions. Con-
tact an INFINITI retailer or professional road
assistance.
– when the sealant has passed its expira- tion date (shown on the label attached to
the bottle)
– when the cut or the puncture is approxi- mately 0.16 in (4 mm) or longer
– when the tire sidewall is damaged
– when the vehicle has been driven with extremely low tire pressure
– when the tire has come off the inside or the outside of the wheel.
– when the tire wheel is damaged
– when two or more tires are flat

Seats:Check seat position controls such as
seat adjusters, seatback recliners, etc. to en-
sure they operate smoothly and that all latches
lock securely in every position. Check that the
head restraints move up and down smoothly
and that the locks (if so equipped) hold securely
in all latched positions.
Steering wheel: Check for changes in the steer-
ing conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that all
warning lights and chimes are operating prop-
erly.
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 washers 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 un-
der severe condition require frequent checks of
the battery fluid level.
Brake and clutch fluid levels*:
Make sure that
the brake and clutch fluid levels are between
the MAX and MIN lines on the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belt*: Make sure that the drive belt
is not frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level surface 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 by an INFINITI retailer. (See
“PRECAUTIONS WHEN STARTING AND DRIVING”
in the “5. Starting and driving” section for
exhaust gas (Carbon monoxide).)
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 cor-
rected immediately.
Power steering fluid level* and lines:
Check the
level 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, deformation, rot or loose
connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
“CLEANING EXTERIOR” in the “7. Appearance
and care” section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.
8-4Maintenance and do-it-yourself

●Check your local regulations.
(Perform steps 4 to 7 only when the engine
oil filter change is needed.)
4. Loosen the oil filter2with an oil filter
wrench. Remove the oil filter by turning it
by hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old rubber gasket re-
maining on the mounting surface of the engine.
Failure to do so could lead to engine damage.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten ad-
ditionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(14.7 to 20.5 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the drain
plug with a wrench.
Drain plug tightening torque:22 to 29 ft-lb
(29 to 39 N·m)
Do not use excessive force.
9. Refill the engine with the recommended oil through the oil filler opening, and
install the oil filler cap securely.
See “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section for drain and
refill capacity. The drain and refill capacity
depends on the oil temperature and drain time.
Use these specifications for reference only.
Always use the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation
1. Install the engine undercover into positionas the following steps.
a. Pull the center of the small plastic clips out.
b. Hold the engine undercover into position.
c. Insert the clips through the undercover into the holes in the frame, then push the
center of the clips in to lock the clips in
place.
d. Install the bolts that hold the undercover in place. Be careful not to strip the bolts
or over-tighten them.
2. Lower the vehicle carefully to the ground.
3. Dispose of waste oil and filter properly.
WARNING
●Prolonged and repeated contact with used
engine oil may cause skin cancer.
●
Try to avoid direct skin contact with used oil. If
skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
● Keep used engine oil out of the reach of
children.
8-10Maintenance and do-it-yourself

ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower amperage
rating than that specified on the fuse box cover.
This could damage the electrical system or
cause a fire.If any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition switch is pushed to
the OFF or LOCK position and the head-
light switch is turned to OFF.
2. Open the engine hood and remove the cover on the battery and the fuse/fusible
link holder.
3. Remove the fuse/fusible link holder cover.
4. Remove the fuse with the fuse puller located in the passenger compartment
fuse box. 5. If the fuse is open
A, replace it with a
new fuse
B. Spare fuses are stored in the
passenger compartment fuse box.
6. If a new fuse also opens, have the elec- trical system checked and repaired by an
INFINITI retailer.
Fusible links
If any electrical equipment does not operate
and the fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace only with genuine INFINITI
parts.

8-20Maintenance and do-it-yourself

If any undesirable driveability problems such as
engine stalling or hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refueling.
Gasoline containing oxygenates can cause paint
damage.
E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed on
level roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.
CAUTION
●Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
● U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.
9-4Technical and consumer information

Due to legal requirements in some states/areas
or provinces, your vehicle may be required to be
in what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Place the ignition switch in the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20
seconds and then blinks for 10 seconds, the I/M
test condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”.
Contact an INFINITI retailer to set the “ready
condition” or to prepare the vehicle for testing.This vehicle is equipped with an Event Data Re-
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an air bag deployment or hitting a
road obstacle, data that will assist in under-
standing how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less. The
EDR in this vehicle is designed to record such
data as:
●
How various systems in your vehicle were
operating;
● Whether or not the driver and passenger
safety belts were buckled/fastened;
● How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
● How fast the vehicle was traveling.
● Sounds are not recorded.
These data can help provide a better under-
standing of the circumstances in which crashes
and injuries occur. NOTE: EDR data are recorded
by your vehicle only if a nontrivial crash situa-
tion occurs; no data are recorded by the EDR
under normal driving conditions and no personal
data (e.g. name, gender, age and crash location)
are recorded. However, other parties, such as
law enforcement, could combine the EDR data with the type of personally identifying data rou-
tinely acquired during a crash investigation.
To read data recorded by an EDR, special equip-
ment is required and access to the vehicle or the
EDR is needed. In addition to the vehicle manu-
facturer and INFINITI retailer, other parties, such
as law enforcement, that have the special equip-
ment, can read the information if they have ac-
cess to the vehicle or the EDR. EDR data will only
be accessed with the consent of the vehicle
owner or lessee or as otherwise required or per-
mitted by law.
