2018 INFINITI QX60 four wheel drive

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.
BRAKE SYSTEM
Starting and driving5-141

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
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.

TIRE PRESSURE MONITORING
SYSTEM (TPMS) (if so equipped)
This vehicle is equipped with the Tire Pres-
sure Monitoring System (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is lit,
and the “Tyre Pressure Low - Add Air” warn-
ing appears in the vehicle information display,
one or more of your tires is significantly
under-inflated. If equipped, the system also
displays pressure of all tires (except the spare
tire) on the display screen by sending a signal
from a sensor that is installed in each wheel. If
the vehicle is being driven with low tire pres-
sure, the TPMS will activate and warn you of
it by the low tire pressure warning light. This
system will activate only when the vehicle is
driven at speeds above 25 km/h (16 mph).
For additional information, refer to “Warning
lights, indicator lights and audible reminders”
in the “Instruments and controls” section and
“Tire Pressure Monitoring System (TPMS)” in
the “Starting and driving” section of this
manual.
WARNING
∙ Radio waves could adversely affect elec-tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
∙ If the low tire pressure warning light illu- minates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage could
occur and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the tire placard to turn the low tire pres-
sure warning light OFF. If you have a flat
tire, replace it with a spare tire as soon as
possible. ∙ When replacing a wheel without TPMS
such as the spare tire, TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you visit
an INFINITI retailer for these services.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road and away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to
P (Park).
4. Turn off the engine.

Front-Wheel Drive (FWD) models
with Continuously Variable
Transmission (CVT)
INFINITI recommends that your vehicle be
towed with the driving (front) wheels off the
ground or place the vehicle on a flatbed truck
as illustrated.
CAUTION
∙ Never tow CVT models with the frontwheels on the ground or four wheels on
the ground (forward or backward), as
this may cause serious and expensive
damage to the transmission. If it is neces-
sary to tow the vehicle with the rear
wheels raised always use towing dollies
under the front wheels.
∙ When towing CVT models with the rear wheels on the ground or on towing
dollies: – Place the ignition switch in the OFF
position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by placing
the ignition switch in the LOCK posi-
tion. This may damage the steering
lock mechanism (for models with a
steering lock mechanism).
VEHICLE RECOVERY
(freeing a stuck vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck
vehicle:
∙ Contact a professional towing service torecover the vehicle if you have any ques-
tions regarding the recovery procedure.
∙ Tow chains or cables must be attached only to main structural members of the
vehicle.
∙ Do not use the vehicle tie-downs to tow or free a stuck vehicle.
∙ Only use devices specifically designed for vehicle recovery and follow the manufac-
turer’s instructions.LCE2371

Outside the vehicle
The maintenance items listed here should be
performed from time to time unless other-
wise specified.
Doors and hoodCheck that all doors and the
hood operate smoothly as well as the back
door, trunk lid and hatch. Also make sure that
all latches lock securely. Lubricate if neces-
sary. Make sure that the secondary latch
keeps the hood from opening when the pri-
mary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights* Clean the headlights on a regular ba-
sis. Make sure that the headlights, stop lights,
tail lights, turn signal lights and other lights
are all operating properly and installed se-
curely. Also check the aim of the headlights.
Tires* Check the pressure with a gauge often
and always prior to long distance trips. Adjust
the pressure in all tires, including the spare, to
the pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire rotation* In the case that Two-Wheel
Drive (2WD) and front and rear tires are same
size; tires should be rotated every 10,000 km
(6,000 miles). 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.
In the case that Four-Wheel Drive and All
Wheel Drive (4WD/AWD) and front and rear
tires are the same size; tires should be rotated
every 5,000 km (3,000 miles). Tires marked
with directional indicators can only be ro-
tated between front and rear. Make sure that
the directional indicators point in the direc-
tion of wheel rotation after the tire rotation is
completed.
In the case that front tires are different size
from rear tires; tires cannot be rotated.
The timing for tire rotation may vary accord-
ing to your driving habits and the road sur-
face conditions.
Tire Pressure Monitoring System (TPMS)
transmitter components (if so equipped)
Re-
place 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 un-
even or abnormal tire wear, there may be a
need for wheel alignment. If the steering wheel or seat vibrates at normal highway
speeds, wheel balancing may be needed.
Windshield
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Repair as
necessary.
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 periodic maintenance, cleaning
the vehicle, etc.
Accelerator pedal Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Brake pedal* Check the pedal for smooth
operation and make sure that it is the proper
distance from the floor mat when depressed
fully. Check the brake booster function. Be
sure to keep the floor mat away from the
pedal.
Parking brake* Check the parking brake op-
eration regularly. Check that the lever (if so
equipped) or the pedal (if so equipped) has
the proper travel. Also make sure that the

TYPES OF TIRES
WARNING
∙ When changing or replacing tires, be sureall four tires are of the same type (i.e.,
Summer, All Season or Snow) and con-
struction. An INFINITI retailer may be
able to help you with information about
tire type, size, speed rating and
availability.
∙ Replacement tires may have a lower speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the low tire pressure
warning system. ∙ Always use tires of the same type, size,
brand, construction and tread pattern on
all four wheels. Failure to do so may re-
sult in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunction re-
sulting in personal injury or death, exces-
sive tire wear and may damage the trans-
mission, transfer case and differential
gears.
All-Wheel Drive (AWD) models
CAUTION
∙ ONLY use spare tires specified for the AWD model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
that you visit an INFINITI retailer for this
service.
All season tires
INFINITI specifies All Season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All Season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than All Season
tires and may be more appropriate in some
areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating
“M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use
of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of
the tire.
8-34Maintenance and do-it-yourself

If you install snow tires, they must be the
same size, brand, construction and tread pat-
tern on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some states,
provinces and territories prohibit their use.
Check local 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.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on 235/55R20 size tires. Installation of the
tire chains/cables on 235/55R20 size tires
will cause damage to the vehicle. If you plan
to use tire chains/cables, you should install
235/65R18 size tires on your vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size for
the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions. Use only SAE class “S” chains. Class
“S” chains are used on vehicles with restricted
tire to vehicle clearance. Vehicles that can use
Class “S” chains are designed to meet the minimum clearances between the tire and the
closest vehicle suspension or body compo-
nent required to accommodate the use of a
winter traction device (tire chains or cables).
The minimum clearances are determined us-
ing the factory equipped tire size. Other types
may damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose end
links of the tire chain must be secured or
removed to prevent the possibility of whip-
ping action damage to the fenders or under-
body. If possible, avoid fully loading your ve-
hicle when using tire chains. In addition, drive
at a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely affected.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the tires ev-
ery 10,000 km (6,000 miles) for 2WD ve-
hicles and 5,000 km (3,000 miles) for AWD
vehicles.
For additional information on tire replacing
procedures, refer to “Flat tire” in the “In case
of emergency” section of this manual.
As soon as possible, tighten the wheel nuts
to the specified torque with a torque wrench.
