ECU INFINITI Q50 2018 Owner's Guide

commended you have the system
checked, and if necessary repaired, by
an INFINITI retailer promptly.
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running,
it may indicate a potential emission control
malfunction.
The malfunction indicator light may also
come on steady if the fuel-filler cap is loose
or missing, or if the vehicle runs out of fuel.
Check to make sure the fuel-filler cap is
installed and closed tightly, and that the
vehicle has at least 3 US gallons (11.4 liters)
of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission
control system malfunction exists.
If this indicator light remains on for 20
seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance test.
(See “Readiness for Inspection/Mainte-
nance (I/M) test (US only)” (P.10-25).) Operation:
The malfunction indicator light will come on
in one of two ways:
. Malfunction indicator light on steady —
An emission control system malfunction
has been detected. Check the fuel-filler
cap if the Loose Fuel Cap warning
appears in the vehicle information dis-
play. If the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off after a few driving
trips. If thelight does not turn off
after a few driving trips, have the vehicle
inspected. It is recommended you visit an
INFINITI retailer for this service. You do
not need to have your vehicle towed to
the retailer.
. Malfunction indicator light blinking — An
engine misfire has been detected which
may damage the emission control sys-
tem.
To reduce or avoid emission control
system damage:
1) Do not drive at speeds above 45 MPH (72 km/h).
2) Avoid hard acceleration or decelera- tion.
3) Avoid steep uphill grades.
4) If possible, reduce the amount of cargo being hauled or towed. The malfunction indicator light may stop
blinking and remain on.
Have the vehicle inspected. It is recom-
mended you visit an INFINITI retailer for
this service. You do not need to have
your vehicle towed to the retailer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary could
lead to poor driveability, reduced fuel
economy, and possible damage to the
emission control system.
Security indicator light
The light blinks when the ignition switch is in
the ACC, OFF or LOCK position. This
function indicates the security system
equipped on the vehicle is operational.
If the security system is malfunctioning, this
light will remain on while the ignition switch
is in the ON position. For additional informa-
tion, see “Security systems” (P.2-30).

This warning appears when the low tire
pressure warning light in the meter illumi-
nates and low tire pressure is detected. The
warning appears each time the ignition
switch is placed in the ON position as long
as the low tire pressure warning light
remains illuminated. If this warning appears,
stop the vehicle and adjust the pressure to
the recommended COLD tire pressure
shown on the Tire and Loading Information
label. (See “Low tire pressure warning light”
(P.2-12) and “Tire Pressure Monitoring
System (TPMS)” (P.5-5).)
16. Flat Tire - Visit dealer warning
(if so equipped)
This warning appears when the low tire
pressure warning light in the meter illumi-
nates and one or more flat tires are detected
while driving. A chime also sounds for
approximately 10 seconds. (See “Low tire
pressure warning light” (P.2-12) and “Tire
Pressure Monitoring System (TPMS)” (P.5-
5).)
17. Low oil pressure warning (for
VR30DDTT engine models)
This warning appears if low engine oil
pressure is detected. If the warning appears
during normal driving, pull off the road in a
safe area, stop the engine immediately and
call an INFINITI retailer or other authorized
repair shop.
The low oil pressure warning is not designed
to indicate a low oil level. Use the dipstick to
check the oil level. (See “Engine oil” (P.8-
10).)
18. Low oil level warning (for 2.0L
turbo gasoline engine models)
This warning appears if low engine oil level is
detected. If this warning appears, check the
oil level using the dipstick. (See “Engine oil”
(P.8-10).)
CAUTION
The oil level should be checked regularly
using the engine oil dipstick. Operating
with an insufficient amount of oil can
damage the engine and such damage is
not covered by the warranty.

Your vehicle has two types of security
systems, as follows:
.Vehicle security system
. INFINITI Vehicle Immobilizer System
The security condition will be shown by the
security indicator light.
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual
and audio alarm signals if someone opens
the doors, hood, or trunk lid when the
system is armed. It is not, however, a motion
detection type system that activates when a
vehicle is moved or when a vibration occurs.
The system helps deter vehicle theft but
cannot prevent it, nor can it prevent the theft of interior or exterior vehicle compo-
nents in all situations. Always secure your
vehicle even if parking for a brief period.
Never leave your Intelligent Key(s) in the
vehicle, and always lock it when unattended.
Be aware of your surroundings, and park in
secure, well-lit areas whenever possible.
Many devices offering additional protection,
such as component locks, identification
markers, and tracking systems, are available
at auto supply stores and specialty shops.
Your INFINITI retailer may also offer such
equipment. Check with your insurance com-
pany to see if you may be eligible for
discounts for various theft protection fea-
tures.

How to arm the vehicle security
system
1. Close all windows.The system can be armed even if the
windows are open.
2. Push the ignition switch to the OFF position.
3. Remove the Intelligent Key from the vehicle.
4. Close all doors, hood and trunk. Lock all doors. The doors can be locked with the
Intelligent Key, door handle request
switch, power door lock switch or me-
chanical key. 5. Confirm that the security indicator light
comes on. The security indicator light
stays on for about 30 seconds. The
vehicle security system is now pre-
armed. After about 30 seconds the
vehicle security system automatically
shifts into the armed phase. The security
light begins to flash once every approxi-
mately 3 seconds. If, during this 30-
second pre-arm time period, the door is
unlocked, or the ignition switch is pushed
to ACC or ON, the system will not arm.
Even when the driver and/or passengers
are in the vehicle, the system will activate
with all doors, hood, and trunk lid locked
with the ignition switch in the LOCK
position. When pushing the ignition switch
to the ACC or ON position, the system will
be released.
Vehicle security system activation
The vehicle security system will give the
following alarm:
. The headlights blink and the horn sounds
intermittently.
. The alarm automatically turns off after
approximately 1 minute. However, the
alarm reactivates if the vehicle is tam-
pered with again. The alarm is activated by:
.
Unlocking the door or opening the trunk
lid without using the button on the
Intelligent Key, the door handle request
switch, one touch unlock sensor or the
mechanical key. (Even if the door is
opened by releasing the door inside lock
knob, the alarm will activate.)
. Opening the hood.
How to stop an activated alarm
The alarm will stop by unlocking a door by
pushing the UNLOCK button on the Intelli-
gent Key, the door handle request switch,
touching the one touch unlock sensor or
using the mechanical key. The alarm will not
stop if the ignition switch is placed in the
ACC or ON position.
If the system does not operate as described
above, it is recommended you have it
checked by an INFINITI retailer.

The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-held
transmitters into one built-in device.
HomeLink® Universal Transceiver:
.Will operate most Radio Frequency (RF)
devices such as garage doors, gates,
home and office lighting, entry door
locks and security systems.
. Is powered by your vehicle’s battery. No
separate batteries are required. If the
vehicle’s battery is discharged or is
disconnected, HomeLink® will retain all
programming.
When the HomeLink® Universal Transcei-
ver is programmed, retain the original
transmitter for future programming proce-
dures (Example: new vehicle purchases).
Upon sale of the vehicle, the programmed
HomeLink® Universal Transceiver buttons
should be erased for security purposes. For
additional information, refer to “Program-
ming HomeLink®” (P.2-58).
WARNING
. Do not use the HomeLink® Universal
Transceiver with any garage door
opener that lacks safety stop and
reverse features as required by fed-
eral safety standards. (These stan- dards became effective for opener
models manufactured after April 1,
1982). A garage door opener which
cannot detect an object in the path of
a closing garage door and then auto-
matically stop and reverse, does not
meet current federal safety stan-
dards. Using a garage door opener
without these features increases the
risk of serious injury or death.
. During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage
door, gate, etc. that you are pro-
gramming.
. Your vehicle’s engine should be
turned off while programming the
HomeLink® Universal Transceiver.
Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.
PROGRAMMING HomeLink®
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site
at: www.homelink.com or call 1-800-355-
3515.
NOTE:
It is also recommended that a new battery
be placed in the hand-held transmitter of
the device being programmed to
HomeLink® for quicker programming and
accurate transmission of the radio-fre-
quency.
1. Position the end of your hand-held
transmitter 1-3 in (26-76 mm) away
from the HomeLink® surface, keeping
the HomeLink® indicator light
in view.
