2021 INFINITI Q50 traction control

SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
.A scraper and stiff-bristled brush to
remove ice and snow from the windows
and wiper blades.
. A sturdy, flat board to be placed under
the jack to give it firm support.
. A shovel to dig the vehicle out of
snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
. Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip”
under these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.
. Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will
lose even more traction. .
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances on
slippery roads.
. Watch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steer-
ing maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the engine
block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours, depending on
outside temperatures, to properly warm
the engine coolant. Use an appropriate
timer to turn the engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
WARNING
.Do not use your engine block heater
with an ungrounded electrical system
or a 2-pronged adapter. You can be
seriously injured by an electrical
shock if you use an ungrounded
connection.
. Disconnect and properly store the
engine block heater cord before
Starting and driving5-135

.Increase your following distance to allow
for increased stopping distances.
. Avoid sudden maneuvers, hard cornering
and hard braking.
WARNING
. Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling stabi-
lity is reduced, which could lead to an
accident and personal injury. Also,
driving a long distance at high speeds
may damage the tire.
. Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than approximately 93 miles
(150 km) with a punctured run-flat
tire. The actual distance the vehicle
can be driven on a flat tire depends on
outside temperature, vehicle load,
road conditions and other factors.
. Drive safely at reduced speeds. Avoid
hard cornering or braking, which may
cause you to lose control of the
vehicle.
. If you detect any unusual sounds or
vibrations while driving with a punc-
tured run-flat tire, pull off the road
to a safe location and stop the vehicle as soon as possible. The tire may be
seriously damaged and need to be
replaced.
CAUTION
.
Never install tire chains on a punctu-
red run-flat tire, as this could damage
your vehicle.
. Avoid driving over any projection or
pothole, as the clearance between
the vehicle and the ground is smaller
than normal.
. Do not enter an automated car wash
with a punctured run-flat tire.
. It is recommended you have the
punctured tire inspected by an
INFINITI retailer or other authorized
repair shop. Replace the tire as soon
as possible if the tire is seriously
damaged.
TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on 265/35RF19 tires. Doing so
will cause damage to the vehicle. If you
plan to use tire chains/cables, you
should install 245/40RF19 tires on your
vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions. Use only SAE Class S chains. Class
“S” chains are used on vehicles with re-
stricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed to
meet the SAE standard minimum clearances
between the tire and the closest vehicle
suspension or body component required to
accommodate the use of a winter traction
device (tire chains or cables). The minimum
clearances are determined using the factory
equipped tire size. Other types may damage
your vehicle. Use chain tensioners when
recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of

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

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.
