2018 INFINITI QX30 brakes

•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 deacti-
vate VDC.
CHARACTERISTICS OF VDC
If theVDC warning light goes out before
beginning the journey, VDC is automatically
active.
If VDC intervenes, the
VDC warning
light flashes in the combination meter.
If VDC intervenes:
•Do not deactivate VDC under any circum-
stances.
•When pulling away, only depress the ac-
celerator 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 sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate VDC in the situations de-
scribed in the following section.
You can select between the following sta-
tuses of VDC:
•VDC is activated.
•VDC is deactivated.
It may be best to deactivate VDC in the fol-
lowing situations:
•When using snow chains.
•In deep snow.
•On sand or gravel. NOTE
Activate VDC as soon as the situations de-
scribed above no longer apply. VDC will oth-
erwise 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
vehicle 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 button on the steering
wheel. The current selection is displayed.
5. To activate/deactivate: press the
button again.
VDC is deactivated if the
warning
light in the combination meter lights up
continuously when the engine is running.
Characteristics when VDC is deactivated:
If VDC is deactivated and one or more wheels
start to spin, the
VDC warning light
flashes in the combination meter. In such
situations, VDC will not stabilize the vehicle.

If the brakes do not operate properly, it is
recommended that you have the brakes
checked. It is recommended that you visit an
INFINITI retailer for this service.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes. The disc-type brakes self-adjust ev-
ery time the brake pedal is applied.Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and fuse rating. The fuse ratings are
listed in the fuse allocation chart.
If the newly inserted fuse also blows, have
the cause traced and rectified. It is recom-
mended you visit an INFINITI retailer for this
service.
The fuses in your vehicle disconnect faulty
circuits. if a fuse blows, all the components on
the circuit and their functions will fail.
BEFORE REPLACING A FUSE
•Secure the vehicle against rolling away.
•Switch off all electrical consumers.
•Remove the key from the ignition lock.
The fuses are located in various fuse boxes:
•Fuse box in the engine compartment on
the left-hand side of the vehicle, when
viewed in the direction of travel.
•Fuse box in the front-passenger footwell.
The fuse allocation chart is on the fuse box in
the front-passenger footwell.
ENGINE COMPARTMENT
WARNING
Never use a fuse of higher or lower amper-
age rating than that specified on the fuse
box cover. This could damage the electrical
system or electronic control units or cause
a fire.

primary latch is released. When driving in ar-
eas using road salt or other corrosive materi-
als, check lubrication frequently.
Lights*:
Clean the headlights on a regular basis. Make
sure that the headlights, stop lights, tail lights,
turn signal lights, and other lights are all op-
erating properly and installed securely. Also
check the aim of the headlights.
Road wheel nuts (lug nuts)*:
When checking the tires, make sure no wheel
nuts are missing, and check for any loose
wheel nuts. Tighten if necessary.
Tire rotation*:
Tires should be rotated every 5,000 miles
(8,000 km). Tires marked with directional
indicators can only be rotated between front
and rear. Make sure that the directional indi-
cators point in the direction of wheel rotation
after the tire rotation is completed.
Tires*:
Check the pressure with a gauge often and
always prior to long distance trips. Adjust the
pressure in all tires to the pressure specified.
Check carefully for damage, cuts or excessive
wear.Tire Pressure Monitoring System (TPMS)
transmitter components:
Replace the TPMS transmitter grommet seal,
valve core and cap when the tires are re-
placed due to wear or age.
Wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, re-
fer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular basis.
Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Wiper blades*:
Check for cracks or wear if not functioning
correctly. Replace as necessary.Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal:
Check the pedal for smooth operation and
make sure that the pedal does not catch or
require uneven effort. Keep the floor mat
away from the pedal.
Automatic transmission P (Park) mecha-
nism:
On a fairly steep hill, check that your vehicle is
held securely when P (Park) has been acti-
vated, without applying any brakes.
Brake pedal*:
Check the pedal for smooth operation. If the
brake pedal suddenly goes down further than
normal, the pedal feels spongy or the vehicle
seems to take longer to stop, have your ve-
hicle checked immediately. It is recommended
you visit an INFINITI retailer for this service.
Keep the floor mat away from the pedal.
Brakes:
Check that the brakes do not pull the vehicle
to one side when applied.
