ECU INFINITI QX30 2018 Manual PDF

•The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstruction of the
sensor area such as ice, snow, stickers,
for example. In these cases, the system
may not be able to warn the driver prop-
erly. Be sure that you check, clean and
clear the sensor area regularly.
•Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
SYSTEM TEMPORARILY
UNAVAILABLE
If the FEB stops working due to a malfunc-
tion or some other reason, one of the follow-
ing three messages will be displayed in the
vehicle information display.
•[Emergency Brake Currently Unavailable
See Operator's Manual]
•[Emergency Brake Inoperative]
•[Radar Sensors Dirty See Operator's
Manual]
For each of these messages, possible causes
and solutions are listed below. [Emergency Brake Currently Unavailable
See Operator's Manual]:
The FEB system is
temporarily inoperative. Possible causes:
•The radar sensor system is temporarily in-
operative, for example, due to electro-
magnetic radiation emitted by nearby TV
or radio stations or other sources of elec-
tromagnetic radiation.
•The system is outside the operating tem-
perature range.
•The on-board voltage is too low.
Once the causes listed above no longer apply,
the display message goes out. The FEB sys-
tem is operative again.
If the display message does not disappear:
•Pull over and stop the vehicle safely as
soon as possible, paying attention to road
and traffic conditions.
•Secure the vehicle against rolling away.
•Switch off the engine.
[Emergency Brake Inoperative]: The FEB
system is temporarily inoperative due to a
malfunction. The adaptive brake assist func-
tion may also have failed.
It is recommended you visit an INFINITI re-
tailer. [Radar Sensors Dirty See Operator's
Manual]:
The FEB system is temporarily re-
stricted or inoperative. Possible causes:
•The sensor behind the INFINITI logo is
dirty.
•The function of the FEB system is im-
paired due to heavy rain or snow.
A warning tone also sounds.
Once the causes listed above no longer apply,
the display message goes out. The FEB sys-
tem is operative again.
If the display message does not disappear:
•Pull over and stop the vehicle safely as
soon as possible, paying attention to road
and traffic conditions.
•Secure the vehicle against rolling away.
•Switch off the engine.
•Clean the area around the sensors.
•Restart the engine. The display message
disappears.
5-68Starting and driving

7. Stop as soon as the sonar function soundsthe continuous warning tone, if not be-
fore. Maneuvering may be required in
tight parking spaces.
The [Park Assist active Select D Observe
surroundings] message appears in the ve-
hicle information display.
8. Select transmission position D (Drive) while the vehicle is stationary.
IPA immediately steers in the other direc-
tion.
The [Park Assist Observe surroundings]
message appears in the vehicle informa-
tion display.
NOTE
You will achieve the best results by wait-
ing for the steering procedure to com-
plete before pulling away.
9. Drive forwards and be ready to brake at all times.
Maneuvering may be required in tight
parking spaces. Drive forward and back
up as prompted by the IPA and sonar
function warning displays, several times if
necessary. 10. Stop as soon as the sonar function
sounds the continuous warning tone, if
not before.
The [Park Assist active Select R] [Ob-
serve surroundings] message appears in
the vehicle information display.
As soon as the parking procedure is
complete the [Park Assist switched off]
message appears and a warning tone
sounds. The vehicle is now parked.
11. Before leaving the vehicle, secure the ve- hicle against rolling away unintentionally:
•The electric parking brake must be ap-
plied.
•The transmission must be in position P
(Park) and the transmission position
display must show P in the vehicle
information display.
•The key must be removed from the
ignition switch.
•On uphill or downhill gradients, the
front wheels must be turned towards
the curb.
IPA no longer supports you with steering in-
terventions. When IPA is finished, you must
steer again yourself. The sonar function is still
available. Parking tips:
•The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of
the location. It may be the case that IPA
guides you too far into a parking space, or
not far enough into it. In some cases, it
may also lead you across or onto the curb.
If necessary you should cancel the parking
procedure with IPA.
•During the parking maneuver, the system
will indicate when you should shift to R
(Reverse) or D (Drive). However, you can
freely choose to shift gear whenever you
feel you need to. Should the transmission
change take place too early, the parking
procedure will be canceled. A sensible
parking position can no longer be achieved
from this position.
EXITING A PARKING SPACE
In order that IPA can support when exiting
the parking space:
•You need to have parked using IPA.
•The border of the parking space must be
high enough at the front and the rear. A
curb stone is too small, for example.
5-74Starting and driving

CAUTION
Never tow the vehicle with one axle raised.
This may damage the differential. Damage
of this sort is not covered by the warranty.
All wheels must be fully raised (see "Four-
Wheel Drive (4WD) models" in the "6. In
case of emergency" section)
4WD, together with VDC, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4WD
can neither reduce the risk of an accident nor
override the laws of physics. 4WD cannot
take account of road, weather, and traffic
conditions. 4WD is only an aid. You are re-
sponsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If a drive wheel spins due to insufficient grip
•When pulling away, only depress the ac-
celerator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum
effectiveness of 4WD can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
WARNING
•Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
•Safe parking procedures require that
both the parking brake be applied and
the P (Park) position engaged. Failure to
do so could cause the vehicle to move
unexpectedly or roll away and result in
an accident.
•When parking the vehicle, make sure the
P (Park) position is engaged. The shift
lever cannot be moved out of the P
(Park) position without depressing the
brake pedal.
•Never leave the engine running while the
vehicle is unattended.
•Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or move the
vehicle. Unattended children could be-
come involved in serious accidents.
•To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others, or pets unattended in your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or death
to people and pets.
CAUTION
Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its
drive train could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
•The electric parking brake must be applied.
•The transmission must be in position P
(Park) and the transmission position dis-
play must show P in the vehicle informa-
tion display.
•The key must be removed from the ignition
switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb.
PARKING
5-88Starting and driving

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,

RUN-FLAT TIRES
With special run-flat tires, you can continue
to drive your vehicle even if there is a total
loss of pressure in one or more tires. The
affected tire must not show any clearly visible
damage.
You can recognize run-flat tires by the mark-
ing which appears on the tire side wall. You
will find this marking next to the tire size
designation, the load-bearing capacity and
the speed index.
Run-flat tires may only be used in conjunction
with an activated tire pressure loss warning
system or tire pressure monitor.
Pressure loss warning message
If a pressure loss warning message appears
in the vehicle information display:
•Observe the instructions in the display
messages.
•Check the tire for damage.
•If driving on, observe the following notes.
The driving distance possible in run-flat mode
is approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
20 miles (30 km) when the vehicle is fully
laden.NIC2686

The wheel lock bolt can only be removed
with the wheel lock key. A key number is
necessary if you need to duplicate the
wheel lock key. Record the key number as shown on the
key code card on the “Security informa-
tion” page at the end of this manual and
keep it in a safe place, not in the vehicle. If
you lose the wheel lock key, it is recom-
mended you see your INFINITI retailer for
a duplicate with the original wheel lock
key code.
Make sure to keep the lock key in the
vehicle. Otherwise, wheels cannot be re-
moved and the service cannot be per-
formed.

In case of emergency6-9

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.
