wheel alignment INFINITI QX55 2023 Owners Manual

The non-viewable areaO2is highlighted in
yellow for several seconds after the bird’s-
eye view is displayed. It will be shown only the
first time after the ignition switch is placed in
the ON position.
In addition, the non-viewable corners are dis-
played in red and will blink for the first 3
seconds
O3to remind the drivers to be
cautious. Predicted course lines
O4indicate the pre-
dicted course when operating the vehicle.
The predicted course lines will be displayed
on the monitor when the steering wheel is
turned. The predicted course lines will move
depending on how much the steering wheel is
turned.
When the monitor displays the front view and
the steering wheel turns about 90 degrees or
less from the neutral position, the two green
predicted course lines are shown in front of
the vehicle.
When the steering wheel turns about 90 de-
grees or more, one green predicted course
line is shown in front of the vehicle and the
other predicted course line is shown at the
side of the vehicle.
When the monitor displays the rear view, the
predicted course lines are shown at the back
of the vehicle.WARNING
• Objects in the bird's-eye view will appear
further than the actual distance.
• Tall objects, such as a curb or vehicle,
may be misaligned or not displayed at
the seam of the views.
• Objects that are above the camera can-
not be displayed.
• The view of the bird's-eye view may be
misaligned when the camera position
alters.
• A line on the ground may be misaligned
and is not seen as being straight at the
seam of the views. The misalignment will
increase as the line proceeds away from
the vehicle.

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire wear
and lowers fuel economy.
• Keep all the wheels in correct alignment. Improper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2).
If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.
If the AWD error warning message is dis-
played, there may be a malfunction in the
Intelligent AWD system. Reduce vehicle
speed and have your vehicle checked as soon
as possible. It is recommended that you visit
an INFINITI retailer for this service. The AWD high temperature message may be
displayed while trying to free a stuck vehicle
due to increased oil temperature. The driving
mode may change to 2-Wheel Drive (2WD).
If this message is displayed, stop the vehicle
with the engine idling, as soon as it is safe to
do so. Then if the message turns off, you can
continue driving.

Other Tire-related Terminology
In addition to the many terms that are
defined throughout this section, In-
tended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears manu-
facturer, brand, and/or model name
molding that is higher or deeper than
the same molding on the other side-
wall of the tire, or (2) the outward
facing sidewall of an asymmetrical tire
that has a particular side that must
always face outward when mounted
on a vehicle.
TYPES OF TIRES
WARNING
• When changing or replacing tires, be sure
all four tires are of the same type (i.e.,
Summer, All Season or Snow) and con-
struction. An INFINITI retailer may be
able to help you with information about
tire type, size, speed rating and
availability.
• Replacement tires may have a lower
speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the low tire pressure
warning system.
• Always use tires of the same type, size,
brand, construction and tread pattern on
all four wheels. Failure to do so may re-
sult in a circumference difference be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunction re-
sulting in personal injury or death, exces-
sive tire wear and may damage the
transmission, transfer case and differen-
tial gears. •
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.
All-Wheel Drive (AWD) models
CAUTION
• ONLY use spare tires specified for the
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
that you visit an INFINITI retailer for this
service.
All season tires
INFINITI specifies All Season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
Season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than All Season
tires and may be more appropriate in some
areas.

If the low tire pressure warning light illumi-
nates continuously and the “Flat Tire – Visit
dealer" warning appears in the vehicle infor-
mation display:
• Do not exceed 50 mph (80 km/h).
• Increase your following distance to allowfor increased stopping distances.
• Avoid sudden maneuvers, hard cornering and hard braking.
WARNING
• Although you can continue driving with a
punctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and per-
sonal 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 ap-
proximately 93 miles (150 km) with a
punctured run-flat tire. The actual dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature, ve-
hicle load, read 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 vi-
brations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.
CAUTION
• Never install tire chains on a punctured
run-flat tire, as this could damage your
vehicle.
• Avoid driving over any projection or pot-
hole, as the clearance between the ve-
hicle and the ground is smaller than
normal.
• Do not enter an automated car wash
with a punctured run-flat tire.
• Have the punctured tire inspected by an
INFINITI retailer or other authorized re-
pair shop. Replace the tire as soon as
possible if the tire is seriously damaged. •
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 difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears (AWD models).
• ONLY use spare tires specified for the
AWD model.
• If excessive tire wear is found, it is rec-
ommended that all four tires be replaced
with tires of the same size, brand, con-
struction and tread pattern. The tire
pressure and wheel alignment should
also be checked and corrected as neces-
sary. It is recommended that you visit an
INFINITI retailer for this service.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on P255/45RF20 size tires. Installation of
the tire chains/cables on P255/45RF20
size tires will cause damage to the vehicle.
If you plan to use tire chains/cables, you
should install P235/55RF19 size tires on
your vehicle.

Doors and engine hood:Check that the doors
and engine hood operate properly. Also en-
sure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary
latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication
frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch fully open. If the hood, trunk, or rear
hatch is not held open, have the gas stays or
struts replaced.
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 miss-
ing, and check for any loose wheel nuts.
Tighten if necessary.
Tire rotation*: Rotate tires at the specified
interval shown in the maintenance schedule.
Tires*: Check the pressure with a gauge of-
ten and always prior to long distance trips. If necessary, adjust the pressure in all tires, in-
cluding the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
tire pressure sensor:
It is recommended that
you replace the TPMS tire pressure sensor
assembly 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 un-
even or abnormal tire wear, there may be a
need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, re-
fer 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. It is recommended that you have
a damaged windshield repaired by an INFINITI
retailer, or an INFINITI Certified Collision Cen- ter. To locate a collision center in your area,
refer to http://collision.infinitiusa.com.
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.
Brake pedal: Check the pedal for smooth op-
eration. 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 that 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.
Continuously Variable Transmission (CVT) P
(Park) position mechanism: On a fairly steep
hill check that the vehicle is held securely with
the shift position in the P (Park) position
without applying any brakes.
