2023 INFINITI QX50 tire pressure

NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge brakes.
If you are considering use of a weight-
distributing hitch system with a surge
brake-equipped trailer, check with the surge
brake, hitch or trailer manufacturer to de-
termine if and how this can be done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface.With the ignition switch in the ON position
and the doors closed, allow the vehicle to
stand for several minutes so that it can
level.
2. Measure the height of a reference point on the front and rear bumpers at the cen-
ter of the vehicle.
3. Attach the trailer to the vehicle and adjust the hitch equalizers so that the front
bumper height is within0-.5inches (0 –
13 mm) of the reference height measured
in step 2. The rear bumper should be no
higher than the reference height mea-
sured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no higher
than the measured reference height when
the trailer is attached. If the rear bumper is
higher than the measured reference height
when loaded, the vehicle may handle un-
predictably which could cause a loss of ve-
hicle control and cause serious personal in-
jury or property damage.
Sway control device
Sudden maneuvers, wind gusts, and buffet-
ing caused by other vehicles can affect trailer
handling. Sway control devices may be used
to help control these affects. If you choose to
use one, contact a reputable trailer hitch sup-
plier to make sure the sway control device will
work with the vehicle, hitch, trailer and the
trailer's brake system. Follow the instructions
provided by the manufacturer for installing
and using the sway control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 2,000 lbs.
(907 kg).
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 3,500 lbs.
(1,587 kg).
Tire pressures
• When towing a trailer, inflate the vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information label.
• Trailer tire condition, size, load rating and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer's specifications.
Safety chains
Always use suitable safety chains between
your vehicle and the trailer. The safety chains
should be crossed and should be attached to
the hitch, not to the vehicle bumper or axle.
The safety chains can be attached to the
bumper if the hitch ball is mounted to the
bumper. Be sure to leave enough slack in the
chains to permit turning corners.
10-28Technical and consumer information

Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while us-
ing the vehicle tail light, stop light and turn
signal circuits as a signal source. The
module/converter must draw no more
than 15 milliamps from the stop and tail
lamp circuits. Using a module/converter
that exceeds these power requirements
may damage the vehicle's electrical sys-
tem. See a reputable trailer retailer to ob-
tain the proper equipment and to have it
installed.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, contact an INFINITI
retailer or reputable trailer retailer. Vehicles
equipped with the optional trailer tow pack-
age are equipped with a 7-pin trailer harness
connector. If your trailer is equipped with a
flat 4-pin connector, an adapter will be
needed to connect the trailer lights to the
vehicle. Adapters are available at auto parts
stores and hitch retailers.
Trailer brakes
Most states require a separate braking sys-
tem on trailers with a loaded weight above a
specific amount, make sure the trailer meets
the local regulations and the regulations
where you plan to tow.
Several types of braking systems are
available.
Surge Brakes - The surge brake actuator is
mounted on the trailer tongue with a hydrau-
lic line running to each trailer wheel. Surge
brakes are activated by the trailer pushing
against the hitch ball when the tow vehicle is
braking. Hydraulic surge brakes are common
on rental trailers and some boat trailers. In
this type of system, there is no hydraulic or
electric connection for brake operation be-
tween the tow vehicle and the trailer.
Electric Trailer Brakes - Electric braking sys-
tems are activated by an electronic signal
sent from a trailer brake controller (special
brake-sensing module).
Have a professional supplier of towing
equipment make sure the trailer brakes are
properly installed and demonstrate proper
brake function testing.
WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
Pre-towing tips
• Be certain your vehicle maintains a level position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose-down
condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
• Always secure items in the trailer to prevent load shift while driving.
• Keep the cargo load as low as possible in the trailer to keep the trailer center of grav-
ity low.
• Load the trailer so approximately 60% of the trailer load is in the front half and 40%
is in the back half. Also make sure the load is
balanced side to side.
• Check your hitch, trailer tire pressure, ve- hicle tire pressure, trailer light operation,
and trailer wheel lug nuts every time you
attach a trailer to the vehicle.
• Be certain your rearview mirrors conform to all federal, state or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.

FUEL RECOMMENDATION:
Use unleaded premium gasoline with an oc-
tane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 87 AKI number (Research oc-
tane number 91) may be temporarily used,
but only under the following precautions:
• Have the fuel tank filled only partially withunleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as
possible.
• Avoid full throttle driving and abrupt acceleration.
Use unleaded premium gasoline for maxi-
mum vehicle performance.
CAUTION
• Using a fuel other than that specified
could adversely affect the emission con-
trol system, and may also affect the war-
ranty coverage.
• Under no circumstances should a leaded
gasoline be used, because this will dam-
age the three-way catalyst. •
Do not use a fuel containing more than
15% ethanol in your vehicle. Your vehicle
is not designed to run on a fuel contain-
ing more than 15% ethanol. Using a fuel
containing more than 15% ethanol in a
vehicle not specifically designed for a
fuel containing more than 15% ethanol
can adversely affect the emission control
devices and systems of the vehicle. Dam-
age caused by such fuel is not covered
by the INFINITI New Vehicle Limited
Warranty.
• Do not use fuel that contains the octane
booster methylcyclopentadienyl man-
ganese tricarbonyl (MMT). Using fuel
containing MMT may adversely affect
vehicle performance and vehicle emis-
sions. Not all fuel dispensers are labeled
to indicate MMT content, so you may
have to consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of MMT
in reformulated gasoline.
•
U.S. government regulations require
ethanol dispensing pumps to be identified
by a small, square, orange and black label
with the common abbreviation or the ap-
propriate percentage for that region.
For additional information, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2).
ENGINE OIL
RECOMMENDATION:
See “Recommended fluids/lubricants and ca-
pacities” (P. 10-2).
COLD TIRE PRESSURE:
For additional information, see “Tire and
Loading Information label” (P. 10-13).
The label is typically located on the driver side
center pillar or on the driver's door. For addi-
tional information, see “Wheels and tires”
(P. 8-27).
RECOMMENDED NEW VEHICLE
BREAK-IN PROCEDURE:
During the first 1,200 miles (2,000 km) of
vehicle use, follow the break-in procedure
recommendations for the future reliability
and economy of your new vehicle. For addi-
tional information, see “Break-in schedule”
(P. 5-132). Failure to follow these recom-
mendations may result in vehicle damage or
shortened engine life.
