2023 INFINITI QX55 warning light

•When using a wheel without TPMS such
as the spare tire, the TPMS will not func-
tion and the low tire pressure warning
light will flash for approximately 1 min-
ute. The light will remain on after 1 min-
ute. Have your tires replaced and/or
TPMS system reset as soon as possible.
It is recommended that you visit an
INFINITI retailer for these services.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
• Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
RUN-FLAT TIRES
This vehicle is equipped with run-flat tires.
Run-flat tires can be used temporarily if they
are punctured. When the “Flat Tire — Visit
dealer” warning appears in the vehicle infor-
mation display, one or more of your tires is
punctured. For additional information, see
“Run-flat tires” (P. 8-36).
For additional information, refer to the tire
safety information in the Warranty Informa-
tion Booklet.
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 tires.
• 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, road 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 diving 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.
6-4In case of emergency

WARNING
Always follow the instructions below. Fail-
ure to do so could result in damage to the
charging system and cause personal injury.
1. If the booster battery is in another vehicle, position the two vehicles to bring their
batteries near each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Engage the P (Park) position. Switch off all unnecessary
electrical systems (lights, heater, air con-
ditioner, etc.). 3. Place the ignition switch to the LOCK or
OFF position.
4. Connect the jumper cables in the se- quence illustrated (
OA,OB,OC,OD).
CAUTION
• Always connect positive (+) to positive
(+) and negative (−) to body ground (for
example, strut mounting bolt, engine lift
bracket, etc.) — not to the battery.
• Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal. 5. Start the engine of the booster vehicle and
let it run for a few minutes.
6. Keep the engine speed of the booster ve- hicle at about 2,000 rpm and start the
engine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, place the ignition
switch in the OFF position and wait 3 to 4
seconds before trying again.
7. After starting the engine, carefully discon- nect the negative cable and then the posi-
tive cable.

TIRE DRESSINGS
INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coating
to the tires to help reduce discoloration of the
rubber. If a tire dressing is applied to the tires,
it may react with the coating and form a
compound. This compound may come off the
tire while driving and stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
• Use a water-based tire dressing. The coat-ing on the tire dissolves more easily than
with an oil-based tire dressing.
• Apply a light coat of tire dressing to help prevent it from entering the tire tread/
grooves (where it would be difficult to
remove).
• Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is com-
pletely removed from the tire
tread/grooves.
• Allow the tire dressing to dry as recom- mended by tire dressing manufacturer. This vehicle has new and unique surfaces on
the center console and door pull finishers. If
cleaning is required use mild soap and water.
However if mild soap and water won’t clean
the center console and door pull finishers, use
Genuine INFINITI Vinyl and Leather Cleaner
(or equivalent).
Occasionally remove loose dust from the in-
terior trim, plastic parts and seats using a
vacuum cleaner or soft bristled brush. Wipe
the vinyl and leather surfaces with a clean,
soft cloth dampened in mild soap solution,
then wipe clean with a dry, soft cloth.
Regular care and cleaning is required in order
to maintain the appearance of the leather.
Before using any fabric protector, read the
manufacturer's recommendations. Some
fabric protectors contain chemicals that may
stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.
Use a slightly moist (with water) microfiber
cloth to clean the wood trim. If necessary, use
water with natural soap or wood dedicated
cleaning products, such as furniture polish.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification sen-
sor. This can also affect the operation of
the air bag system and result in serious per-
sonal injury.
CAUTION
• Never use benzine, thinner, or any similar
material on the interior surfaces or sur-
face damage may occur. Such damage is
not covered under the INFINITI
warranty.
• Small dirt particles can be abrasive and
damaging to leather surfaces and should
be removed promptly. Do not use saddle
soap, car waxes, polishes, oils, cleaning
fluids, solvents, detergents or ammonia-
based cleaners as they may damage the
leather's natural finish.
• Never use fabric protectors unless rec-
ommended by the manufacturer.
• Do not use glass or plastic cleaner on me-
ter or gauge lens covers. It may damage
the lens cover.
CLEANING INTERIOR

CAUTION
Be careful not to burn yourself, as the en-
gine oil is hot.
WARNING
• Prolonged and repeated contact with
used engine oil may cause skin cancer.
• Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
• Keep used engine oil out of reach of
children.
4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
Remove the oil filter by turning it by hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the en-
gine. Failure to do so could lead to an oil
leak and engine damage.
• The dipstick must be inserted in place to
prevent oil spillage from the dipstick hole
when filling the engine with oil.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten addi-
tionally more than 2/3 turn.

plug with a wrench. Do not use excessive
force.
Drain plug tightening torque: 29.4 to 39.2 N·m (22 to 29 ft-lb)
9. Refill the engine with the recommended oil through the oil filler opening, and install
the oil filler cap securely. For additional information about drain and
refill capacity, see “Recommended fluids/
lubricants and capacities” (P. 10-2). The drain
and refill capacity depends on the oil tem-
perature and drain time. Use these specifica-
tions for reference only. Always use the dip-
stick to determine the proper amount of oil in
the engine.
10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required. Turn the engine off
and wait more than 15 minutes. Check
the oil level with the dipstick. Add engine
oil if necessary.
After the operation
1. Reinstall engine protectors in reverse or-der of removal.
2. Lower the vehicle carefully to the ground.
3. Reset the oil control system. For addi- tional information, see “Oil control sys-
tem” (P. 2-25)
• Dispose of waste oil and filter properly.
• Check your local regulations.
