2018 INFINITI QX30 check engine

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.

MessagePossible causes/consequences and solutions
[Check Brake Fluid Level]There is insufficient brake fluid in the brake fluid reservoir.
In addition, the redwarning light lights up in the combination meter and a warning tone sounds.
1. Pull over and stop the vehicle safely as soon as possible, paying attention to road and traffic conditions. Do not continue driving under any circumstances.
2. Secure the vehicle against rolling away.
3. Check the brake fluid level. If brake fluid is necessary, add fluid and have the system checked. It is recommended you visit an
INFINITI retailer for this service. See "Brake fluid" in the "8. Do-it-yourself" section.
4. If the brake fluid level is correct, have the warning system checked. It is recommended you visit an INFINITI retailer for this service.
WARNING•Your brake system may not be working properly if the warning light is on. Driving could be dangerous. If you judge it to be safe,
drive carefully to the nearest service station for repairs. Otherwise, have your vehicle towed because driving it could be
dangerous.
•Pressing the brake pedal with the engine stopped and/or low brake fluid level may increase your stopping distance and braking
will require greater pedal effort as well as pedal travel.
•If the brake fluid level is below the minimum or MIN mark on the brake fluid reservoir, do not drive until the brake system has
been checked. It is recommended you visit an INFINITI retailer for this service.
[Check Brake Pad Wear] The brake pads/linings have reached their wear limit.
It is recommended you visit an INFINITI retailer.

[Emergency Brake
Currently Unavailable See
Operator's Manual] Forward Emergency Braking is temporarily inoperative.
Possible causes:
•The radar sensor system is temporarily inoperative, e.g. due to electromagnetic radiation emitted by nearby TV or radio stations
or other sources of electromagnetic radiation.
•The system is outside the operating temperature range.•The on-board voltage is too low.
Once the causes listed above no longer apply, the display message goes out.
Forward Emergency Braking is operational again.
If the display message does not disappear:
