2018 INFINITI QX30 coolant level

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)" in the "1. 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 en-
gine can cause serious burns, which can oc-
cur 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 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.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions, and switch
off the engine.
Secure the vehicle against rolling away.
2-12Instruments and controls

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" in the "6. In case of emer-
gency" 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 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 " in
the "2. Instruments and controls" section and
"Vehicle 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 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)" in the "5.
Starting and driving" section for more details.
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.
Have the system checked. It is recommended
you visit an INFINITI retailer for these ser-
vices.

roll away There is a risk of an accident
and injury. Therefore, quickly move your
foot from the brake pedal to the accel-
erator pedal. Never leave the vehicle
when it is held by hill start assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake
pedal. This gives you enough time to move
your foot from the brake pedal to the accel-
erator pedal and depress it before the vehicle
begins to roll.
Hill start assist is not active if
•You are pulling away on a level road or a
downhill gradient.
•On vehicles with automatic transmission,
the transmission is in position N.
•The electric parking brake is applied.
•VDC is malfunctioning.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, see
"Engine cooling system" in the "8. Do-it-
yourself" section.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
"Battery" in the "8. Do-it-yourself" section of
this manual.
DRAINING OF ENGINE COOLANT
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see "Changing engine
coolant" in the "8. Do-it-yourself" section of
this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
an INFINITI retailer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, stud- ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial laws before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
3. Tire chains may be used if desired. Make sure they are the proper size for the tires
on your vehicle and are installed according
to the chain manufacturer’s instructions.
Use chain tensioners when recommended
by the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chains
must be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. In addition,

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.
Have your vehicle inspected or repaired. It is
recommended you visit an INFINITI retailer.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the
engine is hot. Always turn off the engine
and wait until it cools down.
•If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
•It is advisable to secure or remove any
loose clothing and any jewelry, such as
rings, watches, etc. before working on
your vehicle.
•If you must run the engine in an enclosed
space such as a garage, be sure there is proper ventilation for exhaust gases to
escape.
•Never get under the vehicle while it is
supported by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
•Always wear eye protection whenever
you work on your vehicle.
•Never leave the engine or the transmis-
sion related component harness connec-
tor disconnected while the ignition
switch is in the ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
