2017 INFINITI QX30 tire pressure

The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the vehicle information dis-
play.
You must not exceed a maximum speed of 50
MPH (80 km/h).
When replacing one or all tires, observe the
following specifications for your vehicle’s tires:
•Size
•Type
•Run-flat mark
If a tire has gone flat and cannot be replaced
with a run flat tire, a standard tire may be used
as a temporary measure. Make sure that you
use the proper size and type (summer or winter
tire).
WARNING
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, pot holes,
off road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
•You hear banging noises.
•The vehicle starts to shake.
•You see smoke and smell rubber.
•VDC is intervening constantly.
•There are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked with regard to their further
use. It is recommended you visit an INFINITI
retailer for this service. The faulty tire must be
replaced.
REMOVING AND FITTING WHEELS
NOTE
A spare wheel is not provided with your vehicle.
Blocking the wheels
WARNING
Make sure to block the appropriate wheel to
prevent the vehicle from moving, which may
cause personal injury.
Place suitable blocks
1in front of and behind
the wheel diagonally opposite the flat tire
Ato
prevent the vehicle from moving when it is on
the jack.

5. Tighten the wheel bolts securely using the
wheel wrench in the sequence as illustrated.
6. Lower the vehicle completely.
7. Install the wheel cover (if equipped).
Wheel
bolt tightening torque: 96 ft-lb (130 N•m, 13
kg-m)
As soon as possible, tighten the wheel bolts to
the specified torque with a torque wrench.
The wheel bolts must be kept tightened to
specification at all times. It is recommended
that the wheel bolts be tightened to specifica-
tion at each maintenance interval.
Adjust the tire pressure to the COLD pressure.
COLD pressure is the tire pressure as measured
after the vehicle has been parked for three hours
or more or driven for less than 1 mile (1.6 km).
COLD tire pressures are shown on the tire and
loading information label affixed to the driver’s
side center pillar.
Wheel lock bolts(if equipped)
In order to prevent theft, the specially designed
wheel lock bolt is installed to each wheel. The
wheel lock bolt cannot be removed with the
commonly used tools.
When removing tires, use the lock key provided
with your vehicle.Removing the wheel lock bolt
:
1. Insert the wheel lock key1to the wheel
lock bolt.
2. To remove the wheel lock bolt, turn the
wheel lock key counterclockwise using the
wheel wrench.
CAUTION
•Do not use a power tool to remove the wheel
lock bolts.
•When installing the wheel, tighten the
wheel lock bolts to the same tightening
torque as the normal wheel bolts. For de-
tails, seeInstalling the wheelearlier in
this section.NOTE
•The wheel lock bolt has an individual code.
A wheel lock key with other than the indi-
vidual code cannot remove the wheel lock
bolt. If you lose the wheel lock key, it is
recommended you contact an INFINITI re-
tailer for a duplicate with the original wheel
lock key code.
•Record the key number and keep it in a safe
place, not in the vehicle.
•When you ask for a service at an INFINITI
retailer, make sure to keep the lock key in
the vehicle. Otherwise, wheels cannot be
removed and the service cannot be per-
formed.

REMOVING SPOTS
Remove tar and oil spots, industrial dust, in-
sects, and tree sap as quickly as possible from
the paint surface to avoid lasting damage or
staining. Special cleaning products are avail-
able at an INFINITI retailer or any automotive
accessory store.
UNDERBODY
In areas where road salt is used in the winter, it
is necessary to clean the vehicle’s underbody
regularly in order to prevent dirt and salt from
building up and causing the acceleration of
corrosion on the underbody and suspension.
Before the winter and again in the spring, the
underseal must be checked and, if necessary,
re-treated.
GLASS
Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for
glass to become coated with a film after the
vehicle is parked in the hot sun. Glass cleaner
and a soft cloth will easily remove this film.
CAUTION
When cleaning the inside of the windows, do
not use sharp-edged tools, abrasive cleaners
or chlorine-based disinfectant cleaners. They
could damage the electrical conductors, radio
antenna elements or rear window defroster
elements.
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 washing
the wheels.
•Inspect wheel rims regularly for dents or
corrosion. This may cause loss of pressure or
damage the tire bead.
•INFINITI recommends that the road wheels
be waxed to protect against road salt in
areas where it is used during winter.
ALUMINUM ALLOY WHEELS
Wash the wheels regularly with a sponge damp-
ened in a mild soap solution, especially during
winter in areas where road salt is used. The salt
residue from road salt could discolor the wheels
if it is not washed off regularly.
CAUTION
Follow the directions below to avoid staining
or discoloring the wheels:
•Do not use a cleaner that uses strong acid or
alkali contents to clean the wheels.
•Do not apply wheel cleaners to the wheels
when they are hot. The wheel temperature
should be the same as ambient tempera-
ture.
•Rinse the wheel to completely remove the
cleaner within 15 minutes after the cleaner
is applied.
CHROME PARTS
Clean all chrome parts regularly with a nonabra-
sive chrome polish to maintain the finish.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the low
tire pressure warning light is lit, one or more of
the tires is significantly under-inflated.
The TPMS will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h). Also,
this system may not detect a sudden drop in tire
pressure (for example a flat tire while driving).
For additional information, refer toTire Pressure
Monitoring System (TPMS)in the5. Starting and
drivingsection.
Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S. label or
the Tire and Loading Information label (if so
equipped) under the Cold Tire Pressure head-
ing. The Tire and Loading Information label is
affixed to the driver side center pillar. Tire
pressures should be checked regularly be-
cause:
•Most tires naturally lose air over time.
•Tires can lose air suddenly when driven over
potholes or other objects or if the vehicle
strikes a curb while parking.
The tire pressures should be checked when the
tires are cold. The tires are considered COLD
after the vehicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6 km) at
moderate speeds.
WARNING
•Improperly inflated tires can fail suddenly
and cause an accident.
•The Gross Vehicle Weight rating (GVWR) is
located on the F.M.V.S. S./C.M.V.S.S. certi-
fication label. The vehicle weight capacity is
indicated on the Tire and Loading Informa-
tion label (if so equipped). Do not load your
vehicle beyond this capacity. Overloading
your vehicle may result in reduced tire life,
unsafe operating conditions due to prema-
ture tire failure, or unfavorable handling
characteristics and could also lead to a se-
rious accident. Loading beyond the speci-
fied capacity may also result in failure of
other vehicle components.
•Before taking a long trip, or whenever you
heavily load your vehicle, use a tire pres-
sure gauge to ensure that the tire pressures
are at the specified level.
•For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the Warranty Information Booklet.

hours, or driven less than 1 mile (1.6 km)
at moderate speeds. The recommended
cold tire inflation is set by the manufac-
turer to provide the best balance of tire
wear, vehicle handling, driveability, tire
noise, etc., up to the vehicle’s GVWR.

TIRE INFLATION PRESSURE
Checking tire pressure
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely onto the
valve stem. Do not press too hard or force
the valve stem sideways, or air will escape. If
the hissing sound of air escaping from the
tire is heard while checking the pressure,
reposition the gauge to eliminate this leak-
age.3. Remove the gauge.
4. Read the tire pressure on the gauge stem
and compare it to the specification shown on
the Tire and Loading Information label.
5. Add air to the tire as needed. If too much air
is added, press the core of the valve stem
briefly with the tip of the gauge stem to
release pressure. Recheck the pressure and
add or release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, includ-
ing the spare.

facturer, brand and/or model name molding
that is higher or deeper than the same molding
on the other sidewall 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, sum-
mer, all season or snow) and construction.
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
they may not match the potential maximum
vehicle speed. Never exceed the maximum
speed rating of the tire.
