2018 INFINITI Q50-HYBRID automatic transmission

8-12Do-it-yourself
When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION
.It is recommended you use only
Genuine NISSAN Matic S ATF. Do
not mix with other fluids.
. Using automatic transmission fluid
(ATF) other than Genuine NISSAN
Matic S ATF may cause deterioration
in driveability and automatic trans-
mission durability, and may damage
the automatic transmission. Damage
caused by the use of fluid other than
as recommended is not covered by
the INFINITI new vehicle limited
warranty. For further brake fluid information, see
“Capacities and recommended fluids/lubri-
cants” (P.10-2) of this manual.
WARNING
.
Use only new fluid from a sealed
container. Old, inferior or contami-
nated fluid may damage the brake
system. The use of improper fluids
can damage the brake system and
affect the vehicle’s stopping ability.
. Clean the filler cap before removing.
. Brake fluid is poisonous and should
be stored carefully in marked con-
tainers out of the reach of children.
CAUTION
Do not spill the fluid on painted surfaces.
This will damage the paint. If fluid is
spilled, wash the surface with water.
JVM0053X
Check the fluid level in the reservoir. If the
fluid is below the MIN lineor the brake
warning light comes on, add Genuine
NISSAN Super Heavy Duty Brake Fluid or
equivalent DOT 3fluid up to the MAX line
.
If fluid must be added frequently, the system
should be checked. It is recommended you
visit an INFINITI retailer for this service.

FLUID (ATF) BRAKE FLUID

other corrosive materials, check lubrication
frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are
missing, and check for any loose wheel nuts.
Tighten if necessary.
Tire rotation*: Tires should be rotated every
5,000 miles (8,000 km).
Tires*: Check the pressure with a gauge
often and always prior to long distance trips.
If necessary, adjust the pressure in all tires,
including the spare, to the pressure speci-
fied. Check carefully for damage, cuts or
excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to wear
or age.
Wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect
uneven or abnormal tire wear, there may be
a need for wheel alignment.
If the steering wheel or seat vibrates at normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other damage.
Have a damaged windshield repaired by a
qualified repair facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your
vehicle is held securely with the shift lever in
the P (Park) position without applying any
brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels spongy or the vehicle seems to take longer to
stop, have your vehicle checked immediately.
It is recommended you visit an INFINITI
retailer for this service. Keep the floor mat
away from the pedal.
Brakes:
Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, it is recommended you
visit an INFINITI retailer for this service.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position. Check
that the head restraints move up and down
smoothly and that the locks (if so equipped)
hold securely in all latched positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjuster and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating

Maintenance items with “$ ” should be
performed more frequently according to
“Maintenance under severe driving condi-
tions” (P.9-13).
(1) Periodic maintenance is not required.
(2) If using a car-top carrier, or driving on
rough or muddy roads, change (not just inspect) oil at every 20,000 miles (32,000
km) or 24 months.
(3) Refer to “Tire rotation” under “General
maintenance” (P.9-2).

CAPACITIES AND RECOMMENDED
FLUIDS/LUBRICANTS

10-18Technical and consumer information
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.6-10).
Automatic Transmission (AT)
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.
