radiator INFINITI QX30 2018 Owner's Manual

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
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"
•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.NIC2833

•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.

should notice any leaks or if gasoline fumes
are evident, check for the cause and have it
corrected immediately.
Radiator and hoses:
Check the front of the radiator and clean off
any dirt, insects, leaves, etc., that may have
accumulated. Make sure the hoses have no
cracks, deformation, rot or loose connec-
tions.

The underbody is frequently exposed to cor-
rosive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust will
form on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information, see
"Cleaning exterior".
