2023 INFINITI QX60 warning

CAUTION
• Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
• Use electrical accessories with the en-
gine running to avoid discharging the ve-
hicle battery.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
Your vehicle is equipped with a variable volt-
age control system. This system measures
the amount of electrical discharge from the
battery and controls voltage generated by
the generator.
The current sensor
OAis located near the
battery along the negative battery cable. If
you add electrical accessories to your vehicle,
be sure to ground them to a suitable body
ground such as the frame or engine block
area.

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 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, see the appropriate
maintenance schedule information in the
"Maintenance and schedules" section of this
manual.
If any electrical equipment does not operate,
check for an open fuse.
Fuses are used in the passenger and engine
compartment. Spare fuses are provided and

If you have a flat tire, see “Flat tire” (P. 6-3).
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all tires
except the spare. When the low tire
pressure warning light is lit and the
“Tire Pressure Low – Add Air” warning
appears in the vehicle information dis-
play, one or more of your tires is sig-
nificantly under-inflated. If equipped,
the system also displays pressure of all tires (except the spare tire) on the dis-
play screen by sending a signal from a
sensor that is installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16
mph (25 km/h). Also, this system may
not detect a sudden drop in tire pres-
sure (for example a flat tire while
driving).
For additional information, see “Low
tire pressure warning light” (P. 2-18),
“Tire Pressure Monitoring System
(TPMS)” (P. 5-5) and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label or the Tire and Loading In-
formation label under the “Cold Tire
Pressure” heading. The Tire and Load-
ing Information label is affixed to thedriver side center pillar. Tire pressures
should be checked regularly 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 mile (1.6 km) at mod-
erate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
see “TPMS with Tire Inflation Indica-
tor” (P. 5-7).

Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING
• Improperly inflated tires can fail
suddenly and cause an accident.
•
The Gross Vehicle Weight Rating
(GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight ca-
pacity is indicated on the Tire and
Loading Information label. Do not
load your vehicle beyond this ca-
pacity. Overloading your vehicle
may result in reduced tire life, un-
safe operating conditions due to
premature tire failure, or unfavor-
able handling characteristics and
could also lead to a serious acci-
dent. Loading beyond the specified
capacity may also result in failure
of other vehicle components.
• Before taking a long trip, or when-
ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level.
•
For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in
the Warranty Information Booklet.
