2018 INFINITI QX60 brake pads

You may feel or hear the system working; this
is normal.
The light will blink for a few seconds after the
VDC system stops limiting wheel spin.
The
indicator light also comes on when
you place the ignition switch in the ON posi-
tion. The light will turn off after approxi-
mately 2 seconds if the system is operational.
If the light does not come on have the system
checked. It is recommended that you visit an
INFINITI retailer for this service.
Turn signal/hazard
indicator lights
The appropriate light flashes when the turn
signal switch is activated.
Both lights flash when the hazard switch is
turned on.
Vehicle Dynamic Control(VDC) OFF indicator light
This indicator light comes on when the VDC
OFF switch is pushed to off. This indicates
the VDC has been turned off.
Push the VDC OFF switch again or restart
the engine and the system will be reactivated.
For additional information, refer to “Vehicle Dynamic Control (VDC) system” in the “Start-
ing and driving” section of this manual.
The VDC light also comes on when the igni-
tion switch is placed in the ON position. The
light will turn off after about 2 seconds if the
system is operational. If the light stays on or
comes on along with the
indicator light
while you are driving, have the VDC system
checked. It is recommended that you visit an
INFINITI retailer for this service.
WARNING
VDC should remain on unless freeing a ve-
hicle from mud or snow.
While the VDC system is operating, you
might feel a slight vibration or hear the sys-
tem working when starting the vehicle or ac-
celerating, but this is normal.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear warn-
ings. When a disc brake pad requires replace-
ment, it makes a high pitched scraping sound
when the vehicle is in motion, whether or not
the brake pedal is depressed. Have the brakes
checked as soon as possible if the warning
sound is heard.
Key reminder chime
A chime sounds if the driver’s door is opened
while the ignition switch is placed in the ACC
or OFF position or placed in the OFF or
LOCK position with the Intelligent Key left in
the vehicle. Make sure the ignition switch is
placed in the LOCK position, and take the
Intelligent Key with you when leaving the
vehicle.
Lane Departure Warning (LDW)
and Lane Departure Prevention
(LDP) warning chime
(if so equipped)
When the LDW or LDP system is on, the
chime sounds if the vehicle is traveling close
to either the left or the right of a traveling
lane with detectable lane markers.
For additional information, refer to “Lane
Departure Warning (LDW) system” or “Lane
Departure Prevention (LDP) system” in the
“Starting and driving” section of this manual.
Light reminder chime
With the ignition switch placed in the OFF
position, a chime sounds when the driver’s
door is opened if the headlights or parking
lights are on.
Instruments and controls2-15

The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle and stopping distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
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.
WARNING
∙ While driving on a slippery surface, becareful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.
∙ 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.
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 pressing 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 cor-
rectly.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or rotors are replaced, in order to
assure the best brake performance. This procedure is described in the INFINITI
Service Manual. It is recommended that you
visit an INFINITI retailer for this service.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
∙ The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving techniques.
It can help maintain vehicle control dur-
ing braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances 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 vehicle in front of
you. Ultimately, the driver is responsible
for safety.
∙ Tire type and condition may also affect braking effectiveness.
– When replacing tires, install the speci- fied size of tires on all four wheels.

∙ Do not modify the vehicle’s suspension. Ifsuspension parts such as shock absorb-
ers, struts, springs, stabilizer bars, bush-
ings and wheels are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the VDC system may not
operate properly. This could adversely
affect vehicle handling performance, and
the
indicator may flash or both
the
andindicator lights may
illuminate.
∙ If brake related parts such as brake pads, rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the VDC system may not operate
properly and both the
and
the
indicator lights may illuminate.
∙ If engine control related parts are not INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate. ∙ When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly
and the
indicator may flash or both
the
andindicator lights 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
indicator may flash or both
the
andindicator lights may
illuminate. This is not a malfunction. Re-
start the engine after driving onto a
stable surface.
∙ If wheels or tires other than the INFINITI recommended ones are used, the VDC
system may not operate properly and
the
indicator may flash or both
the
andindicator lights may
illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow cov-
ered road.
ACTIVE TRACE CONTROL
(if so equipped)
This system senses driving based on the driv-
er’s steering and acceleration/braking pat-
terns, and controls brake pressure at indi-
vidual wheels to help smooth vehicle
response.
When the VDC OFF switch is used to turn off
the VDC system, the active trace control sys-
tem is also turned off.
If the active trace control is not functioning
properly, the FEB OFF indicator light illumi-
nates in the instrument panel.

BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of force
to each of the four wheels depending on the
radius of the turn.
WARNING
∙ The VDC system is designed to help thedriver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully.
∙ Do not modify the vehicle’s suspension. If suspension parts such as shock absorb-
ers, struts, springs, stabilizer bars, bush-
ings and wheels are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the VDC system may not
operate properly. This could adversely
affect vehicle handling performance, and
the
indicator may flash or both
the
andindicator lights may
illuminate. ∙ If brake related parts such as brake pads,
rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the VDC system may not operate

CHECKING BRAKE PEDAL
With the engine running, check the distanceA
between the upper surface of the pedal and
the metal floor. If it is out of the range shown,
it is recommended that you visit an INFINITI
retailer for service.
Distance A: Under depression force of
490 N (110 lbs)
90 mm (3 1/2 in) or more
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes. The front and rear disc-type brakes self-
adjust every time the brake pedal is applied.
WARNING
Have your brake system checked if the
brake pedal height does not return to nor-
mal. It is recommended that you visit an
INFINITI retailer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched scraping
or screeching sound will be heard when the
vehicle is in motion. The noise will be heard
whether or not the brake pedal is depressed.
Have the brakes checked as soon as possible
if the wear indicator sound is heard.
Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does
not affect the function or performance of the
brake system.
Proper brake inspection intervals should be
followed.
For additional information regard-
ing brake inspections, refer to the appropri-
ate maintenance schedule information in the
“INFINITI Service and Maintenance Guide”.
BRAKE BOOSTER
Check the brake booster function as follows:
1. With the engine off, press and release the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to
the next step.
2. While depressing the brake pedal, start the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the engine. Keep the pedal depressed for
about 30 seconds. The pedal height
should not change.
4. Run the engine for one minute without depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression as
the vacuum is released from the booster.
If the brakes do not operate properly, have
the brakes checked. It is recommended that
you visit an INFINITI retailer for this service.
