2018 INFINITI QX60 inflation pressure

Maintenance
The maintenance menu allows the user to set
reminders for various vehicle maintenance
intervals.
WARNING
The tire replacement indicator is not a sub-
stitute for regular tire checks, including tire
pressure checks. For additional informa-
tion, refer to “Changing wheels and tires” in
the “Maintenance and do-it-yourself” sec-
tion of this manual. Many factors including
tire inflation, alignment, driving habits and
road conditions affect tire wear and when
tires should be replaced. Setting the tirereplacement indicator for a certain driving
distance does not mean your tires will last
that long. Use the tire replacement indica-
tor as a guide only and always perform
regular tire checks. Failure to perform
regular tire checks, including tire pressure
checks could result in tire failure. Serious
vehicle damage could occur and may lead to
a collision, which could result in serious per-
sonal injury or death.

2-22Instruments and controls

∙ Keep your engine tuned up. Malfunctionsin the ignition, fuel injection, or electrical
systems can cause overrich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that 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) (if so equipped)
Each tire, including the spare (if provided),
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 TPMS that illuminates
a low tire pressure telltale when one or more
of your tires is significantly under-inflated.
Accordingly, when the low tire pressure tell-
tale illuminates, 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 vehi-
cle’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 thenremain 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
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels al-
low the TPMS to continue to function prop-
erly.
Additional information:
∙ When replacing a wheel without the TPMS such as the spare tire, the TPMS
does not monitor the tire pressure of the
spare tire.
∙ The TPMS will activate only when the vehicle is driven at speeds above 25 km/h
(16 mph). Also, this system may not de-
tect a sudden drop in tire pressure (for
example, a flat tire while driving).
Starting and driving5-5

∙ The low tire pressure warning light doesnot automatically turn off when the tire
pressure is adjusted. After the tire is in-
flated to the recommended pressure, the
vehicle must be driven at speeds above
25 km/h (16 mph) to activate the TPMS
and turn off the low tire pressure warning
light. Use a tire pressure gauge to check
the tire pressure.
∙ The “Tyre Pressure Low - Add Air” warn- ing appears in the vehicle information
display when the low tire pressure warn-
ing light is illuminated and low tire pres-
sure is detected. The “Tyre Pressure Low
- Add Air” warning turns off when the low
tire pressure warning light turns off.
∙ The “Tyre Pressure Low - Add Air” warn- ing appears each time the ignition switch
is placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
∙ The “Tyre Pressure Low - Add Air” warn- ing does not appear if the low tire pres-
sure warning light illuminates to indicate
a TPMS malfunction. ∙ Tire pressure rises and falls depending on
the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure after driving be-
cause the tire pressure rises after driving.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates, check the tire
pressure for all four tires.
∙ The Tire Placard (also referred to as the vehicle placard or tire inflation pressure
label) is located in the driver’s door open-
ing.
∙ You can also check the pressure of all tires (except the spare tire) on the vehicle
information display screen. The order of
the tire pressure figures displayed on the
screen corresponds with the actual order
of the tire position.
For additional information, refer to “Low tire
pressure warning light” and “Tyre Pressure
Low - Add Air” in the “Instruments and con-
trols” section and “Tire Pressure Monitoring
System (TPMS)” in the “In case of emergency”
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. (For additional information, re-
fer to “Flat tire” in the “In case of emer-
gency” section for changing a flat tire.)
5-6Starting and driving

∙ When replacing a wheel without theTPMS such as the spare tire, when a
spare tire is mounted or a wheel is re-
placed, tire pressure will not be indicated,
the TPMS will not function and the low
tire pressure warning light will flash for
approximately 1 minute. The light will re-
main 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 this
service.
∙ 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.
CAUTION
∙ The TPMS may not function properlywhen the wheels are equipped with tire
chains or the wheels are buried in snow.
∙ Do not place metalized film or any metal parts (antenna, etc.) on the windows.
This may cause poor reception of the sig-
nals from the tire pressure sensors, and
the TPMS will not function properly. Some devices and transmitters may tempo-
rarily interfere with the operation of the
TPMS and cause the low tire pressure warn-
ing light to illuminate.
Some examples are:
∙ Facilities or electric devices using similar radio frequencies are near the vehicle.
∙ If a transmitter set to similar frequencies is being used in or near the vehicle.
∙ If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may illu-
minate in the following cases: ∙ If the vehicle is equipped with a wheel and tire without TPMS.
∙ If the TPMS has been replaced and the ID has not been registered.
∙ If the wheel is not originally specified by INFINITI. FCC Notice:

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire, the
TPMS with Tire Inflation Indicator provides
visual and audible signals outside the vehicle
to help you inflate the tires to the recom-
mended COLD tire pressure.
Starting and driving5-7

Vehicle set-up:1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shift lever in the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation: 1. Add air to the tire.
2. After a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. ∙ If the tire is over-inflated more thanapproximately 30 kPa (4 psi), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When
the pressure reaches the designated
pressure, the horn beeps once.
∙ If the hazard indicator does not flash within approximately 15 seconds after
starting to inflate the tire, it indicates
that the TPMS with Tire Inflation Indi-
cator is not operating. ∙ The TPMS will not activate the TPMS
with Tire Inflation Indicator under the
following conditions:
– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation de- vice is not sufficient to inflate the tire.
– There is a malfunction in the TPMS system.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor is low.
∙ If the TPMS with Tire Inflation Indica- tor does not operate due to TPMS
interference, move the vehicle about
1 m (3 ft) backward or forward and try
again.
If the TPMS with Tire Inflation Indicator is
not working, use a tire pressure gauge.ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than pas-
senger cars to make them capable of per-
forming in a variety of on-pavement and off-
road applications. This gives them a higher
center of gravity than ordinary vehicles. An
advantage of higher ground clearance is a
better view of the road, allowing you to an-
ticipate problems. However, they are not de-
signed for cornering at the same speeds as
conventional 2-wheel drive vehicles any more
than low-slung sports cars are designed to
perform satisfactorily under off-road condi-
tions. If at all possible, avoid sharp turns at
high speeds. As with other vehicles of this
type, failure to operate this vehicle correctly
may result in loss of control or vehicle roll-
over. In a rollover crash, an unbelted person is
significantly more likely to die than a person
wearing a seat belt.
For additional information, refer to “Driving
safety precautions” in this section.
5-8Starting and driving

Also, this system may not detect a sudden
drop in tire pressure (for example a flat tire
while driving).
For additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section and “Flat tire” in the “In
case of emergency” section of this manual.
Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifica-
tions are shown on the tire placard under the
“Cold Tire Inflation Pressure” heading. The
tire placard is affixed to the driver side center
pillar. Tire pressures should be checked regu-
larly because:∙ Most tires naturally lose air over time.
∙ Tires can lose air suddenly when driven over potholes or other objects or if the
vehicle strikes a curb while parking.
The tire pressures should be checked when
the tires are cold. The tires are considered
COLD after the vehicle has been parked for 3
or more hours or driven less than 1.6 km
(1 mile) at moderate speeds. The TPMS with tire inflation indicator pro-
vides visual and audible signals outside the
vehicle for inflating the tires to the recom-
mended COLD tire pressure. For additional
information, refer to “TPMS with Tire Infla-
tion Indicator ” in the “Starting and driving”
section of this manual.
Incorrect tire pressure, including under infla-
tion, may adversely affect tire life and ve-
hicle handling.
WARNING
∙ Improperly inflated tires can fail sud-
denly and cause an accident.
∙ Before taking a long trip, or whenever you heavily load your vehicle, use a tire
pressure gauge to ensure that the tire
pressures are at the specified level.
Tire placard
ATire size: The size of the tires originally
installed on the vehicle at the factory.
BTire pressure: Inflate the tires to this
pressure when the tires are cold. Tires
are considered COLD after the vehicle
has been parked for 3 or more hours, or
driven less than 1.6 km (1 mile) at moder-
ate speeds. The recommended cold tire
inflation is set by the manufacturer to
provide the best balance of tire wear and
vehicle handling characteristics based on
the vehicle’s GVWR.

8-32Maintenance and do-it-yourself

Checking tire pressure
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely ontothe valve stem. Do not press too hard or
force the valve stem sideways, or air will
escape. If the hissing of air escaping
from the tire is heard while checking the
pressure, reposition the gauge to elimi-
nate this leakage.
3. Remove the gauge.
4. Read the tire pressure on the gauge stem and compare to the specification
shown on the tire placard. 5. Add air to the tire as needed. If too much
air is added, press the core of the valve
stem briefly with the tip of the gauge
stem to release pressure. Recheck the
pressure and add or release air as
needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, including the spare.

areas where it is used during winter.
Spare tire (TEMPORARY USE
ONLY spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be dam-
aged or involved in an accident:
WARNING
∙ The spare tire should be used for emer-gency use only. It should be replaced with
the standard tire at the first opportunity
to avoid possible tire or differential
damage.
∙ Drive carefully while the TEMPORARY USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
∙ Periodically check spare tire inflation pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 420 kPa, 4.2 bar (60 psi). ∙ With the TEMPORARY USE ONLY spare
tire installed do not drive the vehicle at
speeds faster than 80 km/h (50 mph).
∙ When driving on roads covered with snow or ice, the TEMPORARY USE
ONLY spare tire should be used on the
rear wheels and the original tire used on
the front wheels (drive wheels).
∙ Tire tread of the TEMPORARY USE ONLY spare tire will wear at a faster rate
than the standard tire. Replace the spare
tire as soon as the tread wear indicators
appear.
∙ Do not use the spare tire on other vehicles.
∙ Do not use more than one spare tire at the same time.
∙ Do not tow a trailer when the TEMPO- RARY USE ONLY spare tire is installed.
CAUTION
∙ Do not use tire chains on a TEMPORARYUSE ONLY spare tire. Tire chains will not
fit properly and may cause damage to the
vehicle.
∙ Because the TEMPORARY USE ONLY spare tire is smaller than the original tire,
ground clearance is reduced. To avoid
damage to the vehicle, do not drive over
obstacles. Also, do not drive the vehicle
through an automatic car wash since it
may get caught.
