engine INFINITI QX30 2017 Owners Manual

6.Avoid Idling
•Shutting off your engine when safe for
stops exceeding 30 seconds saves fuel
and reduces emissions.
7.Buy an Automated Pass for Toll Roads
•Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
8.Winter Warm Up
•Limit idling time to minimize impact to
fuel economy.
•Vehicles typically need no more than 30
seconds of idling at start-up to effectively
circulate the engine oil before driving.
•Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
9.Keeping your Vehicle Cool
•Park your vehicle in a covered parking
area or in the shade whenever possible.
•When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system.
•Keep your engine tuned up.
•Follow the recommended scheduled mainte-
nance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
•Use the recommended viscosity engine oil.

mended fluids/lubricants and capacitiesin
the10. Technical informationsection
WARNING
•Do not drive beyond the performance capa-
bility of the tires, even with 4WD engaged.
Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause loss
of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
•For 4WD equipped vehicles, do not attempt to
raise two wheels off the ground and shift the
transmission to any drive or reverse position
with the engine running. Doing so may result
in drivetrain damage or unexpected vehicle
movement which could result in serious ve-
hicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
even if the other two wheels are raised off
the ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with 4WD before it is placed on a
INCREASING FUEL ECONOMY FOUR-WHEEL DRIVE (4WD) (IF EQUIPPED)
Starting and driving5-83

dynamometer. Using the wrong test equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.
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 (seeFour-Wheel Drive
(4WD) modelsin the6. In case of emergency
section)
4WD, together with VDC, improves the traction
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 responsible 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 accel-
erator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum effec-
tiveness of 4WD can only be achieved if you use
winter tires (M+S tires), with snow chains if nec-
essary.
WARNING
•Do not stop or park the vehicle over flam-
mable 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 unexpect-
edly 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.
•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 assistance of others, or
pets unattended in your vehicle. Addition-
ally, the temperature 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.

than four weeks, the battery may be damaged
by exhaustive discharging.
If you leave the vehicle parked up for longer
than six weeks, it may suffer from lack of use.
Visit an INFINITI retailer and seek advice
NOTE
You can obtain information about trickle char-
gers from an INFINITI retailer.The electric power steering system is designed
to reduce the driver effort required to steer the
vehicle.
WARNING
If during operation a fault is detected the fol-
lowing message will be displayed in the ve-
hicle information display along with an audible
warning tone.
[Power Steering Malfunction See Operators
Manual]
In conjunction with this warning, steering as-
sistance will no longer be provided by the sys-
tem.
The effort required to steer the vehicle will
increase. This will be most noticeable at low
speed and when performing a tight turning
maneuver.
Check whether you are able to provide the ex-
tra effort required.
If you are able to steer safely: Carefully drive on
to an INFINITI retailer.
If you are unable to steer safely: Do NOT drive
on. It is recommended you contact the nearest
INFINITI retailer for assistance.
ELECTRIC POWER STEERING SYSTEM
5-86Starting and driving

CAUTION
•If wheels or tires other than INFINITI recom-
mended ones are used, the power steering
system may not operate properly and the
[Power Steering Malfunction See Operators
Manual] warning may appear in the vehicle
information display.
•Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the power steering system may not
operate properly and the [Power Steering
Malfunction See Operators Manual] warn-
ing may appear in the vehicle information
display.
•Do not modify the vehicle’s steering. If
steering parts are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the power steering system
may not operate properly and the [Power
Steering Malfunction See Operators
Manual] warning may appear in the vehicle
information display.
•Do not place the ignition switch in the on
position while the steering wheel or a tire is
removed.
•Do not turn the steering wheel as much as
possible while the ignition switch is in any
position other than the ON position.
•Installing an accessory on the steering
wheel, or changing the steering wheel, may
reduce the steering performance.
NOTE
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assistance for the steering
wheel will be reduced. This is to prevent over-
heating of the electric power steering system
and protect it from becoming damaged. While
the power assistance is reduced, steering wheel
operation will become heavy. When the tem-
perature of the electric power steering system
decreases, the power assistance level will return
to normal. Avoid repeating such steering wheel
operations that could cause the electric power
steering system to overheat.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking ability at two wheels.
BRAKE PRECAUTIONS
WARNING
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or accelerating could cause the
wheels to skid and result in an accident.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle. The stop-
ping distance will be longer.
WARNING
•If the engine is not running or is turned off
while driving, the power assist for the
brakes will not work. Braking will be harder.
•Do not coast with the engine stopped.
BRAKE SYSTEM
Starting and driving5-87

When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
slight pulsation. This is normal and indicates
that the Brake Assist System is operating (if
equipped).
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out
the brake linings/pads faster, and increase fuel
consumption.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or acceleration could cause the
wheels to skid and result in an accident.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.To dry the brakes, drive the vehicle at a safe
speed while lightly depressing the brake pedal
to heat up the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.
Driving uphill
When starting on a steep gradient, it is some-
times difficult to operate the brake. Use the
parking brake to hold the vehicle. When ready
to start, make sure that the shift lever is in an
appropriate forward or reverse driving position,
release the parking brake while depressing the
accelerator pedal. If your vehicle has an electric
parking brake, this will automatically release
when you depress the accelerator pedal (DCT
models).
Driving downhill
The engine braking action is effective for con-
trolling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine braking,
should be selected.
Parking brake break-in
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
The Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent acci-
dents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on normal
surfaces even with ABS. Stopping distances
may also be longer on rough, gravel or snow
covered roads, or if you are using tire chains.
Always maintain a safe distance from the ve-
hicle in front of you. Ultimately, the driver is
responsible for safety.
5-88Starting and driving

Tire type and condition may also affect braking
effectiveness.
–When replacing tires, install the specified
size of tires on all four wheels.
–
When installing a replacement tire, make sure
that it is the proper size and type as specified on
the tire and loading information label. (See
Wheels and Tiresin the9. Maintenance and
Schedulessection.)
–For detailed information, seeWheels and
tiresin the8. Do-it-yourselfsection.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic feature
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 malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, 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 according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. 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 properly. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.
Starting and driving5-89

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, 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 condi-
tions:
– understeer (vehicle tends to not follow
the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to
certain road or driving conditions).
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.When the VDC system operates, the VDC warn-
ing light in the instrument panel flashes so note
the following:
•The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
•You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
•Adjust your speed and driving to the road
conditions.
SeeVehicle Dynamic Control (VDC) warning
lightin the2. Instruments and controlssec-
tion.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
WARNING
•The VDC system is designed to help the
driver maintain stability but does not pre-
vent accidents due to abrupt steering opera-
tion at high speeds or by careless or danger-
ous driving techniques. Reduce vehicle
speed and be especially careful when driv-
ing and cornering on slippery surfaces and
always drive carefully.
•Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the VDC system may not operate
properly. This could adversely affect vehicle
handling performance, and the VDC warning
light
may illuminate.
•If brake related parts such as brake pads,
rotors and calipers are not INFINITI recom-
mended or are extremely deteriorated, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
•If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, the VDC warning light
may
illuminate.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-90Starting and driving

•When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
Do not drive on these types of roads.
•When driving on an unstable surface such
as a turntable, ferry, elevator or ramp, the
VDC warning light
may illuminate. This
is not a malfunction. Restart the engine af-
ter driving onto a stable surface.
•If wheels or tires other than the INFINITI
recommended ones are used, the VDC sys-
tem may not operate properly and the VDC
warning light
may illuminate.
•The VDC system is not a substitute for win-
ter tires or tire chains on a snow covered
road.
•If VDC is malfunctioning, VDC is unable to
stabilize the vehicle. In addition, other driv-
ing safety systems are switched off. This
increases the risk of skidding and an acci-
dent. Drive on carefully. Have VDC checked.
It is recommended you visit an INFINITI re-
tailer for this service.
CAUTION
•When VDC is deactivated, theVDC
OFF warning light lights up continuously.
•If both thewarning light andwarning light are lit continuously, VDC is
not available due to a malfunction.
TRACTION CONTROL SYSTEM (TCS)
The Traction Control System (TCS) is part of
VDC..
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deactivate
VDC.
CHARACTERISTICS OF VDC
If theVDC warning light goes out before
beginning the journey, VDC is automatically
active.
If VDC intervenes, the
VDC warning lamp
flashes in the combination meter.If VDC intervenes:
•Do not deactivate VDC under any circum-
stances.
•When pulling away, only depress the accel-
erator pedal as far as is necessary.
•Adapt your driving style to suit the prevail-
ing road and weather conditions.
Deactivating/activating VDC
WARNING
If you deactivate VDC, VDC no longer stabilizes
the vehicle. There is an increased risk of skid-
ding and an accident.
Only deactivate VDC in the situations de-
scribed in the following section.
You can select between the following statuses
of VDC:
•VDC is activated.
•VDC is deactivated.
It may be best to deactivate VDC in the follow-
ing situations:
•When using snow chains.
•In deep snow.
•On sand or gravel.
Starting and driving5-91

NOTE
Activate VDC as soon as the situations described
above no longer apply. VDC will otherwise not be
able to stabilize the vehicle if the vehicle starts
to skid or a wheel starts to spin.
You can activate/deactivate VDC using the ve-
hicle information display. To activate/
deactivate VDC:
1. Start the engine
2. Press the
orbutton on the
steering wheel to select the [DriveAssist]
menu in the vehicle information display.
3. Press the
orbutton to select
VDC.
4. Press the<OK>button on the steering
wheel. The current selection is displayed.
5. To activate/deactivate: press the<OK>but-
ton again.
VDC is deactivated if the
warning light
in the combination meter lights up continu-
ously when the engine is running.
Characteristics when VDC is deactivated
:
If VDC is deactivated and one or more wheels
start to spin, theVDC warning lamp
flashes in the combination meter. In such situ-
ations, VDC will not stabilize the vehicle.If you deactivate VDC:
•VDC no longer intervenes in understeer or
oversteer situations.
•Engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a
cutting action, so the tires cut through the
loose surface until the hit solid ground,
giving better traction.
•Traction control is still activated.
•VDC still provides support when you brake.
EBD (ELECTRONIC BRAKE FORCE
DISTRIBUTION)
EBD monitors and controls the brake pressure
on the rear wheels to help improve handling
during braking.
WARNING
If EBD is malfunctioning, the EBD [Inoperative
See Operator’s Manual] warning is displayed
in the vehicle information display. The
VDC warning lamp may also light up.
If EBD is malfunctioning as a result of a VDC
malfunction, the rear wheels can lock, e.g. un-
der full braking. This increases the risk of skid-
ding and an accident.You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked. It is recommended
you see an INFINITI retailer.
STEER CONTROL
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilisa-
tion.
This steering support is provided in particular if:
•Both right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
•The vehicle starts to skid.
WARNING
No steering support is provided from STEER
CONTROL, if:
•VDC is malfunctioning.
•The steering is faulty.
Power steering will, however, continue to
function.
