2019 INFINITI QX50 tires

(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may af-
fect 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 on 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
center of the vehicle.
3. Attach the trailer to the vehicle and ad- just the hitch equalizers so that the front
bumper height is within0-.5inches (0 –
13 mm) of the reference height mea- sured in step 2. The rear bumper should
be no higher than the reference height
measured 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 unpre-
dictably which could cause a loss of vehicle
control and cause serious personal injury 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 la-
bel.
∙ Trailer tire condition, size, load rat- ing and proper inflation pressure
should be in accordance with the
trailer and tire manufacturer’s
specifications.

Technical and consumer information

∙ Check your hitch, trailer wiring harnessconnections, and trailer wheel lug nuts
after 50 miles (80 km) of travel and at
every break.
∙ When launching a boat, don’t allow the water level to go over the exhaust tail
pipe or rear bumper.
∙ Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more frequently.
For additional information, refer to the “Do-
it-yourself” section of this manual.
FLAT TOWING FOR FRONT
WHEEL DRIVE VEHICLE (if so
equipped)
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle behind a recreational vehicle, such
as a motor home.
CAUTION
∙ Failure to follow these guidelines can re- sult in severe transmission damage.
∙ Whenever flat towing your vehicle, al- ways tow forward, never backward.
∙ Never tow your front wheel drive vehicle with the front tires on the ground. Doing
so may cause serious and expensive dam-
age to the powertrain.
∙ DO NOT tow your front wheel drive con- tinuously variable transmission vehicle
with all four wheels on the ground (flat
towing). Doing so WILL DAMAGE inter-
nal transmission parts due to lack of
transmission lubrication.
∙ For emergency towing procedures refer to “Towing recommended by INFINITI” in
the “In case of emergency” section of this
manual.
FLAT TOWING FOR ALL–WHEEL
DRIVE VEHICLE (if so equipped)
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle behind a recreational vehicle, such
as a motor home.
CAUTION
∙ Failure to follow these guidelines can re-sult in severe transmission damage.
∙ Never flat tow your All-wheel drive (AWD) vehicle.
∙ DO NOT tow your All-wheel drive (AWD) vehicle with any wheels on the ground.
Doing so may cause serious and expen-
sive damage to the powertrain.
∙ For emergency towing procedures refer to “Towing recommended by INFINITI” in
the “In case of emergency” section of this
manual.
Continuously Variable Transmission
To tow a vehicle equipped with a continu-
ously variable transmission, an appropriate
vehicle dolly MUSTbe placed under the
towed vehicle’s drive wheels. Alwaysfollow
the dolly manufacturer’s recommendations
when using their product.
10-28Technical and consumer information

DOT (Department of Transportation) Quality
Grades: All passenger car tires must conform
to federal safety requirements in addition to
these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one and
one-half (1 1/2) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon the
actual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions onspecified government test surfaces of as-
phalt and concrete. A tire marked C may have
poor traction performance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature A, B and C
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance to
the generation of heat, and its ability to dis-
sipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive tempera-
ture can lead to sudden tire failure. The grade
C corresponds to a level of performance
which all passenger car tires must meet under
the Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, either
separately or in combination, can cause
heat build-up and possible tire failure.

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 with unleaded regular gasoline, and fill up
with unleaded premium gasoline as soon
as possible.
∙ Avoid full throttle driving and abrupt ac- celeration.
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 containing
more than 15% ethanol. Using a fuel con-
taining more than 15% ethanol in a ve-
hicle not specifically designed for a fuel
containing more than 15% ethanol can
adversely affect the emission control de-
vices and systems of the vehicle. Damage
caused by such fuel is not covered by the
INFINITI New Vehicle Limited Warranty.
∙
Do not use fuel that contains the octane
booster methylcyclopentadienyl manga-
nese tricarbonyl (MMT). Using fuel con-
taining MMT may adversely affect vehicle
performance and vehicle emissions. 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 etha-
nol dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropri-
ate percentage for that region.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities” in
the “Technical and consumer information”
section of this manual.
ENGINE OIL
RECOMMENDATION:
• Genuine “Nissan Motor Oil Ester 5W-30
SN” is recommended.
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
COLD TIRE PRESSURE:
Refer to the Tire and Loading Information
label.
The label is typically located on the driver side
center pillar or on the driver’s door. For addi-
tional information, refer to “Wheels and tires”
in the “Do-it-yourself” section of this manual.
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, refer to “Break-in sched-
ule” in the “Starting and driving” section of
this manual. Failure to follow these recom-
mendations may result in vehicle damage or
shortened engine life.
