2018 INFINITI Q70 HYBRID wheel

the tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.

CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires every 5,000 miles (8,000 km).
(See “Flat tire” (P.6-3) for tire repla-
cing procedures.)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.Wheel nut tightening torque:80 ft-lb (108 N·m)
The wheel nuts must be kept tigh- tened to the specification at all times.
It is recommended that wheel nuts be
tightened to the specification at each
tire rotation interval.
WARNING
.
After rotating the tires, check
and adjust the tire pressure.
. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
. Do not include the T-type spare
tire or any other small size
spare tire in the tire rotation.
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

Tire wear and damage
WARNING
. Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found, the tire(s) should be replaced.
. The original tires have built-in
tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
commended you visit an
INFINITI retailer for this ser-
vice.
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. (See “Speci-
fications” (P.10-7) for recommended types
and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted or radial), or
tread patterns can adversely affect
the ride, braking, handling, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects may
lead to accidents and could result in
serious personal injury.
. If your vehicle was originally
equipped with 4 tires that were the
same size and you are only replacing
2 of the 4 tires, install the new tires
on the rear axle. Placing new tires on
the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and
personal injury.

.If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
7) of this manual for wheel off-set
dimensions.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
. The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor. .
When replacing the TPMS sensor, the
ID registration may be required. It is
recommended you visit an INFINITI
retailer for ID registration.
. Do not use a valve stem cap that is
not specified by INFINITI. The valve
stem cap may become stuck.
. Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of pres-
sure.
. Do not install a damaged or deformed
wheel or tire even if it has been
repaired. Such wheels or tires could
have structural damage and could fail
without warning.
. The use of retread tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-
ranty Information Booklet.
Wheel balance
Unbalanced wheels may affect vehicle hand-
ling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required. Wheel balance service should be performed
with the wheels off the vehicle. Spin
balancing the wheels on the vehicle could
lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Spare tire (TEMPORARY USE
ONLY (T-type) spare tire)
Since the spare tire is not equipped with the
TPMS, when a spare tire is mounted (TEM-
PORARY USE ONLY or conventional), the
TPMS will not function.
Observe the following precautions if the T-
type spare tire must be used, otherwise your
vehicle could be damaged or involved in an
accident.
WARNING
.
The T-type spare tire should be used
for emergency use. It should be
replaced with the standard tire at
the first opportunity to avoid possi-
Do-it-yourself8-35

8-36Do-it-yourself
ble tire or differential damage.
. Drive carefully while the TEMPOR-
ARY USE ONLY spare tire is installed.
Avoid sharp turns and abrupt braking
while driving.
. Periodically check spare tire inflation
pressure. Always keep the pressure
of the TEMPORARY USE ONLY
spare tire at 60 psi (420 kPa, 4.2
bar). Always keep the pressure of the
full size spare tire (if so equipped) at
the recommended pressure for stan-
dard tires, as indicated on the Tire
and Loading Information label. For
Tire and Loading Information label
location, see “Tire and Loading In-
formation label” in the index of this
manual.
. With the TEMPORARY USE ONLY
spare tire installed do not drive your
vehicle at speeds faster than 50 MPH
(80 km/h).
. When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on
the front wheels and original tire
used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
. Tire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster rate than the standard tire. Replace
the spare tire as soon as the tread
wear indicators appear.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire
at the same time.
CAUTION
.Do not use tire chains on a TEM-
PORARY USE ONLY spare tire. Tire
chains will not fit properly and may
cause damage to the vehicle.
. Because the TEMPORARY USE
ONLY spare tire is smaller than the
original tire, ground clearance is re-
duced. To avoid damage to the
vehicle, do not drive over obstacles.
Also do not drive the vehicle through
an automatic car wash since it may
get caught.

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 periodic 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.
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.
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.
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
