2018 INFINITI QX30 engine overheat

In the center console (LHD)Rear console Luggage compartment
The power outlet is used for powering elec-
trical accessories such as a cellular telephone.
An emergency cut-off ensures that the on-
board voltage does not drop too low. If the
on board voltage is too low, the power to the
sockets is automatically cut. This ensures that
there is sufficient power to start the engine.
CAUTION
•The outlet and plug may be hot during or
immediately after use.
•Only certain power outlets are designed
for use with a cigarette lighter unit. Do
not use any other power outlet for an
accessory lighter. It is recommended you
visit an INFINITI retailer for additional
information.
•Do not use with accessories that exceed
a 12 volt, 180W (15A) power draw. Do
not use double adapters or more than
one electrical accessory.
•Use this power outlet with the engine
running to avoid discharging the vehicle
battery.
•Avoid using when the air conditioner,
headlights or rear window defogger is
on.
•Push the plug in as far as it will go. If
good contact is not made, the plug may
overheat or the internal temperature
fuse may blow.
•Before inserting or disconnecting a plug,
be sure that the electrical accessory be-
ing used is turned OFF.
•When not in use, be sure to close the cap.
Do not allow water to contact the
outlet.

•Do not stop or park the vehicle over
flammable materials such as dry grass,
wastepaper or rags. They may ignite
and cause a fire.
CAUTION
•Do not use leaded gasoline. (See "Rec-
ommended fluids/lubricants and ca-
pacities" in the "9. Maintenance and
Schedules" section.) Deposits from
leaded gasoline seriously reduce the
ability of the three-way catalyst to help
reduce exhaust pollutants and/or dam-
age the three-way catalyst.
•Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems may cause overrich
fuel to flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-
ommended you visit an INFINITI retailer
for this service.
•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 present),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended 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 monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. 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 driv-
er’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 approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from working
properly. Always check the TPMS telltale af-
ter 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.

•Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
•Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
•Secure heavy loads in the cargo area as
far forward and as low as possible. Do
not equip the vehicle with tires larger
than specified in this manual. This could
cause your vehicle to roll over.
•Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move suddenly
and injure your hands. Instead drive with
your fingers and thumbs on the outside
of the rim.
•Before operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
•Always drive with the floor mats in place
as the floor may become hot.
•Lower your speed when encountering
strong crosswinds. With a higher center of gravity, your INFINITI is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
•Do not drive beyond the performance
capability of the tires, even with AWD
engaged.
•For AWD equipped vehicles, do not at-
tempt 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 drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing), or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle damage or personal injury.
•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
•Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause
loss of control.
•If at all possible, avoid sharp turning ma-
neuvers, particularly at high speeds.
Your INFINITI vehicle has a higher cen-
ter of gravity than a passenger car. The
vehicle is not designed for cornering at
the same speeds as passenger cars. Fail-
ure to operate this vehicle correctly
could result in loss of control and/or a
rollover accident.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
•Be sure to check the brakes immediately
after driving in mud or water. .
•Avoid parking your vehicle on steep hills.
If you get out of the vehicle and it rolls
forward, backward or sideways, you
could be injured.

Holding the vehicle stationary on
uphill gradients
WARNING
If the transmission overheats, the elec-
tronic management system is automati-
cally deactivated. This interrupts the
power transmission from the engine to the
wheels. The vehicle may, for example, roll
backwards on gradients. There is a risk of
an accident. Never hold the vehicle station-
ary on uphill gradients by depressing the
accelerator.
The transmission may overheat if you hold
the vehicle stationary on uphill gradients by
depressing the accelerator pedal. If the trans-
mission overheats, a warning tone sounds
and the [Stop Vehicle Shift to P Leave Engine
Running] display message appears in the ve-
hicle information display. You will only be able
to continue your journey once the transmis-
sion has cooled down and the display mes-
sage in the vehicle information display has
disappeared. Never hold the vehicle stationary on uphill
gradients by depressing the accelerator. In-
stead, only ever hold the vehicle stationary on
uphill gradients by:•Depressing the brake pedal.
•Engaging the electric parking brake.
Kickdown
Use kickdown for maximum acceleration:
•Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
•Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Drive mode switch
The drive mode switch allows you to choose
between drive programs with different driv-
ing characteristics.
Press drive mode switch
1. The selected
drive program appears in the vehicle informa-
tion display.
The automatic transmission switches to drive
program E each time the engine is started.
E (Economy): comfortable, economical driv- ing
S (Sport): sporty driving style
M (Manual): manual gear shifting

•Do not place the ignition switch in the on
position while the steering wheel or a
tire is removed.
•Do not turn the steering wheel as much
as possible while the ignition switch is in
any position other than the ON position.
•Installing an accessory on the steering
wheel, or changing the steering wheel,
may reduce the steering performance.
NOTE
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assistance for
the steering wheel will be reduced. This is to
prevent overheating of the electric power
steering system and protect it from becom-
ing damaged. While the power assistance is
reduced, steering wheel operation will be-
come heavy. When the temperature of the
electric power steering system decreases,
the power assistance level will return to nor-
mal. Avoid repeating such steering wheel
operations that could cause the electric
power steering system to overheat. The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking ability at two wheels.
BRAKE PRECAUTIONS
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.
Vacuum assisted brakes
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle. The stopping distance will be longer.
WARNING
•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.
•Do not coast with the engine stopped. 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 op-
erating (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

WARNING
•Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
•To avoid the danger of being scalded,
never remove the radiator or coolant
reservoir cap while the engine is hot.
When the radiator or coolant reservoir
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
•Do not open the hood if steam is coming
out.
If the engine of your vehicle is overheating
(indicated by the engine coolant temperature
gauge) or if you feel a lack of engine power,
detect unusual noise, etc., proceed as fol-
lows:
1. Move and park the vehicle safely off the road and away from traffic.
2. Turn on the hazard warning flasher lights.
3. Apply the parking brake.
4. Press the P (Park) button. DO NOT STOP THE ENGINE.
5. Open all windows. 6. Switch off the air conditioner system (if
equipped).
7. Set the heater or air conditioner tempera- ture control to maximum “HOT” and fan
speed control to maximum speed.
8. Exit the vehicle.
9. Visually inspect and listen for steam or coolant escaping from the radiator before
opening the hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
10. Open the hood. For details, see "Hood" in the "3. Pre-driving checks and adjust-
ments" section.
11. Visually check if the cooling fan is run- ning.
12. Visually check the radiator and radiator hoses for leakage.
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.
13. After the engine cools down, check the coolant level in the engine coolant reser-
voir with the engine running. Do not
open the radiator cap (if equipped).
14. If the level is low, remove the engine coolant reservoir cap and add coolant
slowly into the reservoir. After refilling
the reservoir to the MAX level, install the
reservoir cap.
15. Close the hood.

WARNING
The engine cooling system is filled at the
factory with a high-quality, year-round,
antifreeze coolant solution. The antifreeze
solution contains rust and corrosion inhibi-
tors, therefore additional cooling system
additives are not necessary.
•Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high-pressure fluid escaping from the
radiator. For additional information on
precautions, refer to "If your vehicle
overheats" in the "6. In case of emer-
gency" section
•The engine coolant reservoir tank is
equipped with a pressure type cap. To
prevent engine damage, use only a
genuine INFINITI pressure cap.
CAUTION
•Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.

•When adding or replacing coolant, be
sure to use only INFINITI Genuine En-
gine Coolant, BASF Glysantin G40 or
equivalent in its quality. The use of other
types of engine coolant may damage the
engine cooling system.
CHECKING ENGINE COOLANT
LEVEL
NOTE
The coolant level must only be checked and
corrected when the engine is cold.
1. Park the vehicle on a level surface.
Only check the coolant level if the vehicle
is on a level surface and the engine is cold. 2. Slowly turn cap
1half a turn counter-
clockwise to allow excess pressure to es-
cape.
3. Turn cap
1further counter-clockwise
and remove it.
If the coolant is at the level of marker bar
3in the filler neck when cold, there is
enough coolant in coolant expansion tank
2.
4. If necessary, top up with INFINITI Genu- ine Engine Coolant, BASF Glysantin G40
or equivalent in its quality.
5. Replace cap
1and turn it clockwise as
far as it will go.
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING
•To avoid 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.
