cooling INFINITI QX30 2018 Owner's Manual

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.

[Check Coolant Level See
Operators Manual]The coolant level is too low.CAUTIONAvoid making long journeys with too little coolant in the engine cooling system. The engine will otherwise be damaged.
Top up the coolant, observing the warning notes before doing so (see "If your vehicle overheats").
If the coolant needs topping up more often than usual. have the engine coolant system checked. It is recommended you visit an
INFINITI retailer for this service.
The fan motor is faulty.
If the coolant temperature is below 250°F (120°C), you can continue driving to the nearest place you can have the system checked.
It is recommended that you visit an INFINITI retailer for this service.
Avoid putting the engine under heavy load as you do so, e.g. driving in mountainous terrain and stop-start traffic.
[Coolant Too Hot Stop
Vehicle Turn Engine Off]The coolant is too hot.
A warning tone also sounds.CAUTIONIf 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
operation of the vehicle may seriously damage the engine. For additional information, refer to "If your vehicle overheats" for
immediate action required.
1. Stop the vehicle immediately, paying attention to road and traffic conditions, and switch off the engine.
2. Secure the vehicle against rolling away
3. Wait until the engine has cooled down.
4. Make sure that the air supply to the engine radiator is not blocked, e.g. by frozen slush.
5. Do not start the engine again until the display message goes out and the coolant temperature is below 120°C. The engine may
otherwise be damaged.
6. Pay attention to the coolant temperature display.
7. If the temperature increases again, have the system checked immediately. It is recommended you visit an INFINITI retailer for
this service.
Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 250°F (120°C).
See "If your vehicle overheats".
Instruments and controls2-45

WARNING
•The heater and air conditioner operate
only when the engine is running.
•Never leave children or adults who
would normally require the support of
others alone in the vehicle. Pets should
not be left alone either. They could un-
knowingly activate switches or controls
and inadvertently become involved in a
serious accident and injure themselves.
On hot, sunny days, temperatures in a
closed vehicle could quickly become high
enough to cause severe or possibly fatal
injuries to people or animals.
•Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
•Do not adjust the heating and air condi-
tioning controls while driving so that
full attention may be given to vehicle
operation.
The heater and air conditioner operate when
the engine is running. The air blower will op-
erate even if the engine is turned off and the
ignition switch is in the ON position.NOTE
•Condensation forms inside the air condi-
tioning unit when the air conditioner (if
equipped) is running, and is safely dis-
charged underneath your vehicle.
Traces of water on the ground are there-
fore normal.
•Odors from inside and outside the vehicle
can build up in the air conditioner unit.
Odor can enter the passenger compart-
ment through the ventilators.
When parking, set the heater and air con-
ditioner controls to turn off air recircula-
tion to allow fresh air into the passenger
compartment. This should help reduce
odors inside the vehicle.
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. To prevent the windows from
misting up
•Switch off climate control only briefly.
•Switch on air-recirculation mode only
briefly.
•Switch on the cooling with air dehumidifi-
cation function.
•Switch on the windshield demisting func-
tion briefly, if required.The air-conditioning system/automatic cli-
mate control regulates the temperature and
the humidity of the vehicle interior and filters
undesirable substances from the air.
The air-conditioning system/automatic cli-
mate control can only be operated when the
engine is running. Optimum operation is only
achieved with the side windows closed.
Always keep the ventilation flaps behind the
side panelling clear. Otherwise the vehicle will
not be ventilated correctly.
NOTE
•Ventilate the vehicle for a brief period dur-
ing warm weather. This will speed up the
cooling process and the desired interior
temperature will be reached more quickly.
•The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. With automatic climate
control, gaseous pollutants and odors will
also be reduced. A clogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason, you should always
observe the interval for replacing the filter,
which is specified in the Service Booklet.
As this depends on environmental condi-
tions, for example heavy air pollution, the
interval may be shorter than stated in the
Service Booklet.
