engine overheat INFINITI QX30 2018 Owner's Manual

TACHOMETER
The tachometer indicates the engine speed in
revolutions per minute (rpm).Do not rev the
engine in the red zone.
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
1when the gauge
needle points within the zone shown in the
illustration. The engine coolant temperature
varies with the outside air temperature and
driving conditions.
CAUTION
If the gauge indicates coolant temperature
near the hot (H) end of the normal range,
reduce vehicle speed to decrease tempera-
ture. If the gauge is over the normal range,
stop the vehicle as soon as safely possible.
If the engine is overheated, continued op-
eration of the vehicle may seriously dam-
age the engine. For additional information,
refer to "If your vehicle overheats" for im-
mediate action required.

If the seat belt warning light flashes, together
with an intermittent warning tone, this means
that the driver or passenger has not fastened
their seat belt, and the speed of the vehicle is
exceeding 15 MPH (25 km/h).
Supplemental Restraint
System (SRS) air bag
warning light
WARNING
If the supplemental air bag warning light is
on, it could mean that the front air bag,
driver's knee air bag, side air bag, curtain
air bag and/or pretensioner systems will
not operate in an accident. To help avoid
injury to yourself or others, have your ve-
hicle checked by an INFINITI retailer as
soon as possible.
When the ignition switch is in the ON posi-
tion, the Supplemental Restraint System
(SRS) air bag warning light illuminates to in-
dicate that the system is operational. The
light then tuns off within a few seconds after
the engine is started.
If any of the following conditions occur, the
front air bag, front seat-mounted side-
impact air bag, roof-mounted curtain air bag
and pretensioner systems need servicing:
•The supplemental air bag warning light
remains on for longer than a few seconds
once the engine is running.
•The supplemental air bag warning light
flashes intermittently.
•The supplemental air bag warning light
does not come on at all.
It is recommended you visit an INFINITI re-
tailer for these services. Unless checked and
repaired, the supplemental restraint system
(air bag system) and/or the pretensioner sys-
tems may not function properly. For addi-
tional information, refer to "Supplemental
Restraint System (SRS)".
Coolant warning light
WARNING
If the coolant warning light is lit, the engine
may not be being cooled sufficiently and
may be damaged.
Never drive with an overheated engine.
Driving when your engine is overheated can
cause some fluids which may have leaked
into the engine compartment to catch fire.
In addition, steam from an overheated en-
gine can cause serious burns, which can oc-
cur just by opening the hood.
There is a risk of injuryIf the red coolant warning light lights up while
the engine is running and the coolant tem-
perature gauge is at the start of the scale, the
temperature sensor for the coolant tempera-
ture gauge is faulty. The coolant temperature
is no longer being monitored. There is a risk of
engine damage if the coolant temperature is
too high.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions, and switch
off the engine. Do not continue driving under
any circumstances.
Consult an INFINITI retailer.
If the red coolant warning light comes on
while the engine is running, with or without
an accompanying warning tone, it could
mean that:
•The coolant level is too low.
•If the coolant level is correct, the airflow to
the engine radiator may be blocked or the
electric engine radiator fan may be mal-
functioning.
•The coolant is too hot and the engine is no
longer being cooled sufficiently.
Observe the additional display messages in
the vehicle information display.
2-12Instruments and controls

Stop the vehicle immediately, paying atten-
tion to road and traffic conditions, and switch
off the engine.
Secure the vehicle against rolling away.
Leave the vehicle and keep a safe distance
from the vehicle until the engine has cooled
down.
Check the coolant level and top up the cool-
ant, observing the warning notes (see "If your
vehicle overheats").
If you have to top up the coolant frequently,
have the engine cooling system checked.
Make sure that the air supply to the engine
radiator is not blocked, e. g. by frozen slush.
Do not start the engine again until the cool-
ant temperature is below 250°F (120°C). The
engine may otherwise be damaged.
Low fuel warning light
This light comes on when the fuel level in the
fuel tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches 0 (Empty).There will be a small re-
serve of fuel in the tank when the fuel gauge
reaches 0 (Empty).
Vehicle Dynamic Control
(VDC) warning light
The VDC warning light blinks when the Ve-
hicle Dynamic Control (VDC) system is oper-
ating, thus alerting the driver to the fact that
the road surface is slippery and the vehicle is
nearing its traction limits.
You may feel or hear the system working, this
is normal.
The light will continue to blink for a few sec-
onds after the VDC system stops limiting
wheel spin.
Cruise control or Intelligent Cruise Control is
deactivated.
For additional information see " Vehicle Dy-
namic Control (VDC) OFF indicator light " and
"Vehicle Dynamic Control (VDC) system".
INDICATOR LIGHTS
Turn signal/hazard indicator
lights
The appropriate light flashes when the turn
signal switch is activated. Both lights flash
when the hazard switch is turned on.
Low beam indicator light
This light comes on when the switch is turned
to the position:
The headlights will come
on and front side, tail, number plate and in-
strument lights remain on.
Vehicle Dynamic Control
(VDC) OFF indicator light
The light comes on when the Vehicle Dy-
namic Control (VDC) has been disabled. This
indicates that the VDC system is not operat-
ing.
Disabling the VDC system causes the For-
ward Emergency Braking system to become
unavailable. See " Forward emergency brak-
ing (FEB) system (if equipped)" for more de-
tails.
This light also comes on briefly when the
ignition switch is turned to the ON position.
The light will turn off after approximately
1 second if the VDC system is operational.
When the VDC OFF indicator light and VDC
warning light (see " Vehicle Dynamic Control
(VDC) warning light" later in this section)
come on with the VDC system turned on, it
alerts the driver to the fact that the system's
fail-safe mode is operating. This means that
the system may not be functioning properly.

WARNING
Do not use or allow occupants to use the
seat heater if you or the occupants cannot
monitor elevated seat temperatures or
have an inability to feel pain in body parts
that contact the seat. Use of the seat
heater by such people could result in seri-
ous injury.
CAUTION
•The battery could run down if the seat
heater is operated while the engine is
not running.
•Do not use the seat heater for extended
periods or when no one is using the seat.
•Do not put anything on the seat which
insulates heat, such as a blanket, cush-
ion, seat cover, etc. Otherwise, the seat
may become overheated.
•Do not place anything hard or heavy on
the seat or pierce it with a pin or similar
object. This may result in damage to the
heater.
•Any liquid spilled on the heated seat
should be removed immediately with a

WARNING
•The exhaust gas and the exhaust system
are very hot. Keep people, animals and
flammable materials away from the ex-
haust system components.
•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".) Deposits from leaded gaso-
line seriously reduce the ability of the
three-way catalyst to help reduce ex-
haust pollutants and/or damage 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 yourtires 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
Starting and driving5-3

•Do not shift gears 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 ac-
cident.
•If your engine stalls or you cannot make
it to the top of a steep hill, never at-
tempt to turn around. Your vehicle could
tip or roll over. Always back straight
down in R (Reverse) gear and apply
brakes to control your speed.
•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.

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.
