2010 INFINITI FX engine overheat

TACHOMETER
The tachometer indicates engine speed in revo-
lutions per minute (RPM).Do not rev the engine
into the red zone
1.
CAUTION
When engine speed approaches the red zone,
shift to a higher gear or reduce engine speed.
Operating the engine in the red zone may cause
serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant tem-
perature.
The engine coolant temperature is within the
normal range when the gauge needle points
within the zone
1shown in the illustration.
The engine coolant temperature varies with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates engine coolant tempera-
ture near the hot (H) end of the normal range,
reduce vehicle speed to decrease temperature.
If gauge is over the normal range, stop the
vehicle as soon as safely possible. If the engine
is overheated, continued operation of the ve-
hicle may seriously damage the engine. See “IF
YOUR VEHICLE OVERHEATS” in the “6. In case of
emergency” section for immediate action
required.

●Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems can cause overrich fuel flow into the
three-way catalyst, causing it to overheat.
Do not keep driving if the engine misfires, or
if noticeable loss of performance or other
unusual operating conditions are detected.
Have the vehicle inspected promptly by an
INFINITI retailer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-way
catalyst.
● Do not race the engine while warming it up.
● Do not push or tow your vehicle to start the
engine.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not beable to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Additional information
●
The TPMS does not monitor the tire pressure
of the spare tire.
● The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h).
Also, this system may not detect a sudden
drop in tire pressure (for example a flat tire
while driving).
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h) to
activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.

A FLAT TIRE” in the “6. In case of emer-
gency” section of this Owner’s Manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces co-
ordination, delays reaction time and impairs
judgement. Driving after drinking alcohol in-
creases the likelihood of being involved in an
accident injuring yourself and others. Addition-
ally, if you are injured in an accident, alcohol
can increase the severity of the injury.
INFINITI is committed to safe driving. However,
you must choose not to drive under the influ-
ence of alcohol. Every year thousands of people
are injured or killed in alcohol-related acci-
dents. Although the local laws vary on what is
considered to be legally intoxicated, the fact is
that alcohol affects all people differently and
most people underestimate the effects of
alcohol. Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter,
prescription, and illegal drugs). Don’t drive if
your ability to operate your vehicle is impaired
by alcohol, drugs, or some other physical con-
dition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal and
off-road use. However, avoid driving in deep
water or mud as your INFINITI is mainly de-
signed for leisure use, unlike a conventional
off-road vehicle.
Remember that Two-Wheel Drive (2WD) models
are less capable than All-Wheel Drive (AWD)
models for rough road driving and extrication
when stuck in deep snow, mud, or the like.
Please observe the following precautions:
WARNING
●
Drive carefully when off the road and avoid
dangerous areas. Every person who drives or
rides in this vehicle should be seated with
their seat belt fastened. This will keep you
and your passengers in position when driv-
ing over rough terrain. ●
Do not drive across steep slopes. Instead
drive either straight up or straight down the
slopes. Off-road vehicles can tip over side-
ways much more easily than they can for-
ward or backward.
● Many hills are too steep for any vehicle. If
you drive up them, you may stall. If you drive
down them, you may not be able to control
your speed. If you drive across them, you
may roll over.
● Do not shift ranges while driving on downhill
grades as this could cause loss of control of
the vehicle.
● Stay alert when driving to the top of a hill. At
the top there could be a drop-off or other
hazard that could cause an accident.
● If your engine stalls or you cannot make it to
the top of a steep hill, never attempt to turn
around. Your vehicle could tip or roll over.
Always back straight down in R (Reverse)
range. Never back down in N (Neutral), using
only the brake, as this could cause loss of
control.
● Heavy braking going down a hill could cause
your brakes to overheat and fade, resulting
in loss of control and an accident. Apply
brakes lightly and use a low range to control
your speed.

BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle and the
stopping distance will be longer.
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.
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 brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-upthe brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.
EUROPEAN DESIGN BRAKE PADS (if so
equipped)
The FX50 Sport (only) is equipped with more
aggressive European style brake pads which
provide increased fade resistance when repeat-
edly braking from very high speeds. These pads
are likely to experience increased brake dust
and noise as well as increased pad and rotor
wear, with replacement intervals of less than
20,000 miles for some customers depending
upon their driving patterns.
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.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of thebrakes, wearing out the brake and pads faster
and reduce gas mileage.
To help save the brakes 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.
WARNING
●
While driving on a slippery surface, be care-
ful when braking, accelerating or downshift-
ing. Abrupt braking or accelerating could
cause the wheels to skid and result in an
accident.
● If the engine is not running or is turned off
while driving, the power assist for the
brakes will not work. Braking will be harder.

CAUTION
●Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
● To avoid the danger of being scalded, never
remove the radiator cap while the engine is
still hot. When the radiator cap is removed,
pressurized hot water will spurt out, possi-
bly causing serious injury.
● Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the selector
lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radia-
tor before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no
steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing or the cooling fan does not run, stop
the engine.
WARNING
Be careful not to allow your hands, hair, jewelry
or clothing to come into contact with, or get
caught in, engine belts or the engine cooling
fan. The engine cooling fan can start at any
time.
7. After the engine cools down, check thecoolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at the nearest INFINITI retailer.
If needed, Roadside Assistance is available.

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze
coolant solution. The antifreeze solution con-
tains rust and corrosion inhibitors, therefore
additional cooling system additives are not
necessary.
WARNING
●Never remove the radiator cap and engine
coolant reservoir cap when the engine is hot.
Wait until the engine and radiator cool down.
Serious burns could be caused by high pres-
sure fluid escaping from the radiator or cool-
ant reservoir. See precautions in “IF YOUR
VEHICLE OVERHEATS” in the “6. In case of
emergency” section of this manual.
● The radiator is equipped with a pressure
type radiator cap. To prevent engine dam-
age, use only a genuine NISSAN radiator cap.
CAUTION
When adding or replacing coolant, be sure to
use only a Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent with
the proper mixture ratio shown in the following
chart. The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km) or 7
years. Mixing any other type of coolant or the
use of non-distilled water will reduce the life
expectancy of the factory-fill coolant. Refer to
the Infiniti Service and Maintenance Guide for
more details. The use of other types of coolant
solutions may damage the engine cooling
system.

CHECKING ENGINE COOLANT LEVEL
Check the coolant level in the reservoir when the
engine is cold. If the coolant level is below MIN
2, open the reservoir tank cap and add coolant
up to the MAX
1level. If the reservoir tank is
empty, check the coolant level in the radiator
when the engine is cold. If there is insufficient
coolant in the radiator, fill the radiator with
coolant up to the filler opening and also add it
to the reservoir tank up to the MAX level
1.
Tighten the cap securely after adding engine
coolant.

(168,000 km) or 7 years. Mixing any other type
of coolant or the use of non-distilled water will
reduce the life expectancy of the factory-fill
coolant. Refer to the NISSAN/INFINITI Service
and Maintenance Guide for more details.
If the cooling system requires coolant fre-
quently, have it checked by an INFINITI retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate INFINITI
Service Manual.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING
●To avoid the danger of being scalded, never
change the coolant when the engine is hot.
●
Never remove the radiator cap when the engine
is hot. Serious burns could be caused by high
pressure fluid escaping from the radiator.
●Avoid direct skin contact with used coolant. If
skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
●Keep coolant out of reach of children and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range
1.
If the oil level is below
2, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill
3.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil mainte-
nance intervals or during the break-in period,
depending on the severity of operating condi-
tions.
CAUTION
Oil level should be checked regularly. Operat-
ing the engine with an insufficient amount of oil
can damage the engine, and such damage is
not covered by warranty.
