engine overheat INFINITI QX30 2017 Owner's Manual

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, re-
duce vehicle speed to decrease temperature. If
the gauge is over the normal range, stop the
vehicle as soon as safely possible. If the en-
gine is overheated, continued operation of the
vehicle may seriously damage the engine. For
additional information, refer to If your vehicle
overheats in the6. In case of emergency
section for immediate action required.
FUEL GAUGE
The fuel gauge indicates the approximatefuel
level in the tank when the ignition switch is in
the ON position.
The gauge may move slightly during braking,
turning, accelerating, or going up and down
hills due to movement of fuel in the tank.
The gauge needle returns to 0 (Empty) after the
ignition switch is placed in the OFF position.
The low fuel warning
appears on the
vehicle information display when the fuel level
in the tank is getting low.
Refill the fuel tank before the gauge registers
0 (Empty).
The arrow,
, indicates that the fuel-filler
lid is located on the left side of the vehicle.

The seat belt warning light may also illuminate
if there are objects on the front passenger seat.
Remove the objects and stow them in a safe
place.
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 vehicle checked by an
INFINITI retailer as soon as possible.
When the ignition switch is in the ON position,
the Supplemental Restraint System (SRS) air
bag warning light illuminates to indicate 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 pre-
tensioner systems need servicing:
•The supplemental air bag warning light re-
mains 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 retailer
for these services. Unless checked and re-
paired, the supplemental restraint system (air
bag system) and/or the pretensioner systems
may not function properly. For additional infor-
mation, refer to Supplemental Restraint Sys-
tem (SRS) in the1. Safety — seats, seat belts
and supplemental restraint system section.
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 engine
can cause serious burns, which can occur just
by opening the hood.
There is a risk of injury
If the red coolant warning light lights up while the
engine is running and the coolant temperature
gauge is at the start of the scale, the temperature
sensor for the coolant temperature gauge is faulty.
The coolant temperature is no longer being moni-
tored. There is a risk of engine damage if the
coolant temperature is too high.
Stop the vehicle immediately, paying attention
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 ac-
companying 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 malfunc-
tioning.

•The coolant is too hot and the engine is no
longer being cooled sufficiently.
Observe the additional display messages in the
vehicle information display.
Stop the vehicle immediately, paying attention
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 coolant,
observing the warning notes (see If your ve-
hicle overheats in the6. In case of emergency
section).
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 coolant
temperature is below 250
oF (120oC). 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 conve-
nient, preferably before the fuel gauge reaches 0 (Empty).
There will be a small reserve 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 Vehicle
Dynamic Control (VDC) system is operating,
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 seconds
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 in the
2. Instruments and controls section andVe-
hicle Dynamic Control (VDC) system in the
5. Starting and driving section.
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 instru-
ment lights remain on.
Vehicle Dynamic Control (VDC)
OFF indicator light
The light comes on when the Vehicle Dynamic
Control (VDC) has been disabled. This indicates
that the VDC system is not operating.
Disabling the VDC system causes the Forward
Emergency Braking system to become unavail-
able. See Forward emergency braking (FEB)
system (if equipped) in the5. Starting and
driving section for more details.
This light also comes on briefly when the igni-
tion 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. Have the

The power outlet is used for powering electrical
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 run-
ning to avoid discharging the vehicle bat-
tery.
•Avoid using when the air conditioner, head-
lights 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

•Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste-
paper or rags. They may ignite and cause a
fire.
CAUTION
•Do not use leaded gasoline. (SeeRecom-
mended fluids/lubricants and capacities in
the 9. Maintenance and Schedules sec-
tion.) Deposits from leaded gasoline seri-
ously reduce the ability of the three-way
catalyst to help reduce exhaust pollutants
and/or damage the three-way catalyst.
•Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems may cause overrich fuel to flow into
the three-way catalyst, causing it to over-
heat. Do not keep driving if the engine mis-
fires, or if noticeable loss of performance or
other unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended 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 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 totire 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 be
able 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 working
properly. Always check the TPMS telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.
Starting and driving5-5

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 accident. Apply
brakes lightly and use a low gear to control
your speed.
•Unsecured cargo can be thrown around
when driving over rough terrain. Properly
secure all cargo so it will not be thrown
forward and cause injury to you or your pas-
sengers.
•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 steer-
ing wheel when driving off-road. The steer-
ing 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 affected by
strong side winds. Slower speeds ensure
better vehicle control.
•Do not drive beyond the performance capa-
bility of the tires, even with AWD engaged.
•For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any drive or reverse po-
sition with the engine running. Doing so
may result in drivetrain damage or unex-
pected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
•Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing), 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 dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpectedvehicle movement which could result in se-
rious vehicle damage or personal injury.
•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel ex-
cessively.
•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 center of grav-
ity than a passenger car. The vehicle is not
designed for cornering at the same speeds
as passenger cars. Failure to operate this
vehicle correctly could result in loss of con-
trol 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 care-
fully.
•Be sure to check the brakes immediately
after driving in mud or water.
