change wheel INFINITI Q50 2020 Owner's Guide

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.10-8) for recommended types
and sizes of tires and wheels.)
After the ignition switch is placed in the ON
position, it may take a period of time for the
tire pressure to be displayed in the vehicle
information display while the vehicle is
driven. Depending on the radio wave circum-
stance, tire pressure may not correctly be
displayed.
WARNING
.The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted, radial or run-
flat), or tread patterns can adversely
affect the ride, braking, handling,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speed-
ometer calibration, headlight aim
and bumper height. Some of these
effects may lead to accidents and
could result in serious personal injury.
. For Two-Wheel Drive (2WD) models,
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-
9) 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 contact 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.
Intelligent All-Wheel Drive (AWD)
models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), and tread pattern
on all four wheels. Failure to do so
may result in a circumference differ-
ence between tires on the front and
rear axles which will cause excessive
tire wear and may damage the trans-
mission, transfer case and differential
gears.
. ONLY use spare tires specified for
the Intelligent AWD model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
you visit an INFINITI retailer for this service.
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.
JACKING UP THE VEHICLE AND
REPLACING TIRES
Your vehicle is equipped with run-flat tires
and you can continue driving to a safe
location even if they are punctured. (See
“Run-flat tires” (P.6-4) and “Run-flat tires”
(P.8-32).)
This section contains the information about
the vehicle jack-up procedures and the tire
replacement. NOTE:
Jacking tools are not equipped as standard
with this vehicle. It is recommended you
contact an INFINITI retailer about acquiring
the tools.
WARNING
.
Make sure the parking brake is
securely applied and the transmission
into the P (Park) position.
. Never change tires when the vehicle
is on a slope, ice or slippery areas.
This is hazardous.
. Never change tires if oncoming traf-
fic is close to your vehicle. Wait for
professional road assistance.

9-4Maintenance and schedules
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
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and
that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe condition require frequent
checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Intercooler coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4).) Fluid leaks:
Check under the vehicle for fuel,
oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.

Left side
This vehicle is equipped with air deflectors in
front of the front wheels. The deflectors will
change the air flow to help improve aero-
dynamic performance.
When transporting your vehicle on a trailer,
the air deflectors may interfere with a steep
slope to a trailer bed. In this case, remove the
deflectors from the undercover of the ve-
hicle.
1. Loosen three screws as shown and remove the left-side air deflector
.
2. Tighten the removed screw
in its
original position.
3. Perform the same procedure to remove the right-side air deflector. 4. Store the two air deflectors and four
screws to reinstall in the reverse order.
5. When reinstalling, make sure all six screws are firmly tightened on both air
deflectors.

for your vehicle. (See “Measurement
of weights” (P.10-18).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
LOADING TIPS
.The GVW must not exceed GVWRor GAWR as specified on the F.M.
V.S.S./C.M.V.S.S. certification la-
bel.
.Do not load the front and rear axleto the GAWR. Doing so will exceed
the GVWR.
WARNING
.Properly secure all cargo to help
prevent it from sliding or shift-
ing. Do not place cargo higher
than the seatbacks. In a sudden
stop or collision, unsecured car-
go could cause personal injury.
.Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts of your vehicle can break, tire
damage could occur, or it can
change the way your vehicle
handles. This could result in loss
of control and cause personal
injury.
.Overloading could not only
shorten the life of your vehicle
and the tires, but also could
lead to hazardous vehicle hand-
ling and long braking distance.
This may cause a premature tire
malfunction, which could result
in a serious accident and perso-
nal injury. Failures caused by
overloading are not covered by
the vehicle’s warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is
loaded, drive to a scale and weigh
the front and the rear wheels sepa-
rately to determine axle loads. Indivi-
dual axle loads should not exceed
either of the gross axle weight ratings(GAWR). The total of the axle loads
should not exceed the gross vehicle
weight rating (GVWR). These ratings
are given on the vehicle certification
label. If weight ratings are exceeded,
move or remove items to bring all
weights below the ratings.
