2023 INFINITI QX55 warning

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 restricted
tire to vehicle clearance. Vehicles that can use
Class “S” chains are designed to meet the
minimum clearances between the tire and the
closest vehicle suspension or body compo-
nent required to accommodate the use of a
winter traction device (tire chains or cables).
The minimum clearances are determined us-
ing the factory equipped tire size. Other types
may damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose end
links of the tire chain must be secured or
removed to prevent the possibility of whip-
ping action damage to the fenders or under-
body. If possible, avoid fully loading your ve-
hicle 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.
Do not use tire chains on dry roads. Driving
with 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 7,500 miles (12,000 km).
For additional information on tire re-
placing procedures, see “Flat tire”
(P. 6-3).
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench. Wheel nut tightening torque:
83 ft-lb (113 N·m)
The wheel nuts must be kept tight-
ened to specifications at all times. It is
recommended that wheel nuts be
tightened to specification at each tire
rotation interval.
WARNING
•
After rotating the tires, check and
adjust the tire pressure.
•Do not include the spare tire in the
tire rotation.
•For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

Tire wear and damage
1. Wear indicator
2. Location mark
WARNING
• Tires should be periodically in-
spected for wear, cracking, bulg-
ing 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 the
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 personal in-
jury. If it is necessary to repair the
spare tire, it is recommended that
you visit an INFINITI retailer for
this service.
• For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. For addi-
tional information, see “Wheels and tires”
(P. 10-9).
WARNING
• The use of tires other than those recom-
mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
adversely affect the ride, braking, han-
dling, VDC system, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, headlight
aim and bumper height. Some of these
effects may lead to accidents and could
result in serious personal injury.
• For 2WD models, if your vehicle was
originally equipped with four tires that
were the same size and you are only re-
placing two of the four 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.
WDI0259
Do-it-yourself8-39

•If the wheels are changed for any reason,
always replace with wheels which have
the same off-set dimension. Wheels of a
different off-set could cause premature
tire wear, degrade vehicle handling char-
acteristics, affect the VDC system
and/or interference with the brake
discs. Such interference can lead to de-
creased braking efficiency and/or early
brake pad wear. For additional informa-
tion on wheel off-set dimensions, see
“Wheels and tires” (P. 10-9).
• When using a wheel without the TPMS,
such as the spare tire, the TPMS will not
function and the low tire pressure
warning light will flash for approxi-
mately 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 that you
visit an INFINITI retailer for this service.
• Replacing tires with those not originally
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 recom-
mended that you visit an INFINITI re-
tailer 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 cor-
rectly fitted. Otherwise the valve may be
clogged up with dirt and cause a mal-
function or loss of pressure.
• Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling 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 balanc-
ing the wheels on the vehicle could lead to
mechanical damage.
•
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information”
(Canada) in the Warranty Information
Booklet.
Care of wheels
• Wash the wheels when washing the vehicle to maintain their appearance.
• Clean the inner side of the wheels when the wheel is changed or the underside of the
vehicle is washed.
• Do not use abrasive cleaners when wash- ing the wheels.
• Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
• INFINITI recommends waxing the road wheels to protect against road salt in areas
where it is used during winter.

9-4Maintenance and schedules

WARNING
• It is extremely dangerous to ride in
a cargo area inside a vehicle. In a
collision, people riding in these ar-
eas are more likely to be seriously
injured or killed.
•
Do not allow people to ride in any
area of your vehicle that is not
equipped with seats and seat belts.
• Be sure everyone in your vehicle is
in a seat and using a seat belt
properly.
TERMS
It is important to familiarize yourself
with the following terms before load-
ing your vehicle:
• Curb Weight (actual weight of your vehicle) - vehicle weight including:
standard and optional equipment,
fluids, emergency tools, and spare
tire assembly. This weight does not
include passengers and cargo. • GVW (Gross Vehicle Weight) - curb
weight plus the combined weight of
passengers and cargo.
• GVWR (Gross Vehicle Weight Rat- ing) - maximum total combined
weight of the unloaded vehicle, pas-
sengers, cargo, hitch, trailer tongue
load and any other optional equip-
ment. This information is located on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label.
• GAWR (Gross Axle Weight Rating) - maximum weight (load) limit speci-
fied for the front or rear axle. This
information is located on the
F.M.V.S.S./C.M.V.S.S. certification
label.
• GCWR (Gross Combined Weight Rating) - The maximum total weight
rating of the vehicle, passengers,
cargo, and trailer. • Vehicle Capacity Weight, Load limit,
Total load capacity - maximum total
weight limit specified of the load
(passengers and cargo) for the ve-
hicle. This is the maximum combined
weight of occupants and cargo that
can be loaded into the vehicle. If the
vehicle is used to tow a trailer, the
trailer tongue weight must be in-
cluded as part of the cargo load. This
information is located on the Tire
and Loading Information label.
• Cargo capacity - permissible weight of cargo, the subtracted weight of
occupants from the load limit.
VEHICLE LOADING INFORMATION
Technical and consumer information10-15

1. Locate the statement “The com-bined weight of occupants and
cargo should never exceed XXX kg
or XXX lbs.” on your vehicle’s
placard.
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and lug-
gage load capacity. For example, if
the “XXX” amount equals 1400 lbs.
and there will be five 150 lb. pas-
sengers in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs. (1400-
750 (5 X 150) = 650 lbs.) 5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your
vehicle.
Towing a trailer with a vehicle that is
not intended for towing may result in
an accident involving injury or death.
WARNING
Do not tow a trailer with your ve-
hicle. Towing a trailer may result in
an accident involving injury or death. Before driving a loaded vehicle, con-
firm that you do not exceed the GVWR
or the GAWR for your vehicle. For ad-
ditional information, see “Measure-
ment of weights” (P. 10-19).
Also check tires for proper inflation
pressures. For additional information,
see “Tire and Loading Information la-
bel” (P. 8-29).
Technical and consumer information10-17

SECURING THE LOAD
There are luggage hooks located in the cargo
area as shown. The hooks can be used to
secure cargo with ropes or other types of
straps.
When securing items using luggage hooks
located on the side finisher do not apply a
load over more than 6.5 lbs. (29 N) to a single
hook.
The luggage hooks that are located on the
floor should have loads less than 110 lbs.
(490 N) to a single hook.
WARNING
• Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
• The child restraint top tether strap may
be damaged by contact with items in the
cargo area. Secure any items in the cargo
area. Your child could be seriously injured
or killed in a collision if the top tether
strap is damaged.
• Do not load your vehicle any heavier than
the GVWR or the maximum front and
rear GAWRs. If you do, parts of your ve-
hicle can break, tire damage could occur,
or it can change the way your vehicle
handles. This could result in loss of con-
trol and cause personal injury.
LOADING TIPS
• The GVW must not exceed GVWR
or GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification
label. • Do not load the front and rear axle
to the GAWR. Doing so will exceed
the GVWR.
WARNING
• Properly secure all cargo with
ropes or straps to help prevent it
from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or colli-
sion, unsecured cargo 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.
