2020 INFINITI Q50 tires

Do not tow a trailer with your
vehicle.
FLAT TOWING
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
result in severe transmission damage.
. Whenever flat towing your vehicle,
always tow forward, never back-
ward.
. DO NOT tow any Automatic Trans-
mission (AT) vehicle with all four
wheels on the ground (flat towing).
Doing so WILL DAMAGE internal
transmission parts due to lack of
transmission lubrication.
. DO NOT tow any All-Wheel Drive
(AWD) vehicle with any of the wheels
on the ground. Doing so may cause
serious and expensive damage to the
powertrain.
. For emergency towing procedures
refer to “Towing recommended by INFINITI” (P.6-9).
Automatic Transmission
All-Wheel Drive (AWD) models:
Do not tow an AWD vehicle with any of the
wheels on the ground.
Two-Wheel Drive (2WD) models:
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly
MUST
be placed under the towed vehicle’s
drive wheels. Alwaysfollow the dolly man-
ufacturer’s recommendations when using
their product. DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where applic-
able 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
government course as a tire graded 100.
The relative performance of tires depends
upon actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road character-
istics and climate.

TOWING A TRAILERUNIFORM TIRE QUALITY GRADING

10-20Technical and consumer information
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 on
specified 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 trac-
tion tests, and does not include accel-
eration, cornering, hydroplaning, or peak
traction characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to
dissipate 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 perfor-
mance which all passenger car tires must
meet under the Federal Motor VehicleSafety 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
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in combina-
tion, can cause heat build-up and possi-
ble tire failure.

FUEL INFORMATION
Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
INFINITI recommends the use of unleaded
premium gasoline with 93 AKI number
(Research octane number 98) to obtain the
maximum vehicle performance and the best
driveability.
If unleaded premium gasoline is not avail-
able, unleaded regular gasoline with an
octane rating of at least 87 AKI number
(Research octane number 91) may be tem-
porarily 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
acceleration.
Use unleaded premium gasoline for max-
imum vehicle performance.
CAUTION
. Using a fuel other than that specified
could adversely affect the emission control system, and may also affect
warranty coverage.
. Under no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
. Do not use a fuel containing more
than 15% ethanol. Your vehicle is not
designed to run on a fuel containing
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. Damage caused by
such fuel is not covered by the
INFINITI new vehicle limited war-
ranty.
. Do not use fuel that contains the
octane booster methylcyclopentadie-
nyl manganese tricarbonyl (MMT).
Using fuel containing 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
ethanol dispensing pumps to be iden-
tified by a small, square, orange and
black label with the common abbre-
viation or the appropriate percen-
tage for that region.
ENGINE OIL RECOMMENDA-
TION:
See “Capacities and recommended fluids/
lubricants” (P.10-2) for engine oil and oil
filter recommendation.
COLD TIRE PRESSURES:
The label is typically located on the driver
side center pillar or on the driver’s door. For
additional information, see “Wheels and
tires” (P.8-26).
NEW VEHICLE BREAK-IN PRO-
CEDURES RECOMMENDATION:
During the first 1,200 miles (2,000 km) of
vehicle use, follow the recommendations
outlined in the “Break-in schedule” (P.5-
119) of this Owner’s Manual. Follow these
recommendations for the future reliability
and economy of your new vehicle.
