service INFINITI QX30 2018 Repair Manual

WARNING
•The exhaust gas and the exhaust system
are very hot. Keep people, animals and
flammable materials away from the ex-
haust system components.
•Do not stop or park the vehicle over
flammable materials such as dry grass,
wastepaper or rags. They may ignite
and cause a fire.
CAUTION
•Do not use leaded gasoline. (See "Rec-
ommended fluids/lubricants and ca-
pacities".) Deposits from leaded gaso-
line seriously reduce the ability of the
three-way catalyst to help reduce ex-
haust pollutants and/or damage the
three-way catalyst.
•Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems may cause overrich
fuel to flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-ommended you visit an INFINITI retailer
for this service.
•Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
•Do not race the engine while warming it
up.
•Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if present),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of yourtires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS

can be driven on a flat tire depends on
outside temperature, vehicle load,
road conditions and other factors.
–If you detect any unusual sounds or
vibrations while driving with a punc-
tured run-flat tire, pull off the road to
a safe location and stop the vehicle as
soon as possible. The tire may be se-
riously damaged and need to be re-
placed.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•If you used Emergency Tire Sealant to
repair a minor tire puncture, the TPMS
sensor should be checked when repair-
ing or replacing the tire (for models
equipped with the emergency tire punc-
ture repair kit). It is recommended you
visit an INFINITI retailer for this service.
•INFINITI recommends using only
INFINITI Genuine Emergency Tire Seal-
ant provided with your vehicle. Other
tire sealants may damage the valve stem
seal which can cause the tire to lose air
pressure (for models equipped with the
emergency tire puncture repair kit).
CAUTION
•The TPMS may not function properly
when the wheels are equipped with
snow chains or the wheels are buried in
snow.
•Do not place metallized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the
signals from the tire pressure sensors,
and the TPMS will not function
properly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pres-
sure suitable for the operating situation (see
"Wheels and tires"). Note that the correct tire
pressure for the current operating situation
must first be taught-in to the tire pressure
monitor (see "Restarting TPMS" later in this
section).
If there is a substantial loss of pressure, the
warning threshold for the warning message
is aligned to the reference values taught-in.
Restart the tire pressure monitor after ad-
justing to the cold tire pressure. The current
pressures are saved as new reference values.
This will ensure that a warning message will
only appear if the tire pressure drops signifi-
cantly.The tire pressure monitor does not warn you
of an incorrectly set tire pressure.
TPMS is not able to warn you of a sudden
loss of pressure, e. g. if the tire is penetrated
by a foreign object. In the event of a sudden
loss of pressure, bring the vehicle to a halt by
braking carefully. Avoid abrupt steering ma-
neuvers.
TPMS has a yellow warning light in the com-
bination meter for indicating a pressure loss
or malfunction. Depending on how the warn-
ing light flashes or lights up, a tire pressure
that is too low or a malfunction in TPMS is
indicated:
•If the warning light is lit continuously, the
tire pressure on one or more tires is signifi-
cantly too low. TPMS is not malfunction-
ing.
•If the warning light flashes for around a
minute and then remains lit constantly, the
TPMS is malfunctioning.
In addition to the warning light, a message
appears in the vehicle information display.
Observe the information on display mes-
sages (see "Safety systems"
It may take up to ten minutes for a malfunc-
tion of the tire pressure monitor to be indi-
cated. A malfunction will be indicated by the

2. Maintain a firm grip on the steering wheel
with both hands and try to hold a straight
course.
3. When appropriate, slowly release the ac-
celerator pedal to gradually slow the ve-
hicle.
4. Gradually steer the vehicle to a safe loca-
tion off the road and away from traffic if
possible.
5. Lightly apply the brake pedal to gradually
stop the vehicle.
6. Turn on the hazard warning flashers and
contact a roadside emergency service to
change the tire. For additional informa-
tion, refer to "Flat tire".
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood of
being involved in an accident injuring your-
self and others. Additionally, if you are in-
jured in an accident, alcohol can increase
the severity of the injury.INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people dif-
ferently and most people underestimate the
effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Don’t
drive if your ability to operate your vehicle is
impaired by alcohol, drugs, or some other
physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is mainly
designed for leisure use, unlike a conventional
off-road vehicle.
Remember that 2–wheel drive vehicles are
less capable than all-wheel drive (AWD)
models for rough road driving and extrication
when stuck in deep snow or mud, or the like.Please observe the following precautions:
WARNING
•Spinning the front wheels on slippery
surfaces may cause the AWD warning
message to display and the AWD system
to automatically switch from the AWD
to 2WD mode. This could reduce the
traction. Be especially careful when
towing a trailer. (AWD models)
•Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle should
be seated with their seat belt fastened.
This will keep you and your passengers
in position when driving over rough ter-
rain.
•Do not drive across steep slopes. Instead
drive either straight up or straight down
the slopes. Off-road vehicles can tip
over sideways much more easily than
they can forward or backward.
•Many hills are too steep for any vehicle.
If you drive up them, you may stall. If you
drive down them, you may not be able to
control your speed. If you drive across
them, you may roll over.

Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle at a low
speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates
the ABS warning light on the instrument
panel. The brake system then operates nor-
mally, but without anti-lock assistance. If the
ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies ac-
cording to road conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving
conditions, the VDC system helps to perform
the following functions.
•Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel
on the same axle.
•Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).
•Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in the
following conditions:
– understeer (vehicle tends to not follow
the steered path despite increased
steering input)
– oversteer (vehicle tends to spin due to
certain road or driving conditions).
The VDC system can help the driver to main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving situ-
ations.
