flat tire INFINITI QX30 2018 User Guide

3. Tire chains may be used if desired. Make
sure they are the proper size for the tires
on your vehicle and are installed according
to the chain manufacturer’s instructions.
Use chain tensioners when recommended
by the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chains
must be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. In addition,
drive at a reduced speed, otherwise, your
vehicle may be damaged and/or vehicle
handling and performance may be ad-
versely affected.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during the winter:
•A scraper and stiff-bristled brush to re-
move ice and snow from the windows.
•A sturdy, flat board to be placed under the
jack to give it firm support.
•A shovel to dig the vehicle out of snow-
drifts.
•Extra washer fluid to refill the windshield
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
•Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or sanded.
•Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more
traction.
•Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
•Allow greater following distances on
slippery roads.
•Watch for slippery spots (glare ice).
These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
•Do not use cruise control on slippery
roads.
•Snow can trap dangerous exhaust gas
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.

The hazard warning flasher switch1oper-
ates regardless of the ignition switch position
except when the battery is discharged.
The hazard warning flasher is used to warn
other drivers when you have to stop or park
under emergency conditions.
When the hazard warning flasher switch is
pushed, all turn signal lights will flash. To turn
off the hazard warning flasher, push the haz-
ard warning switch again.
WARNING
•If stopping for an emergency, be sure to
move the vehicle well off the road.
•Do not use the hazard warning flashers
while moving on the highway unless un-
usual circumstances force you to drive
so slowly that your vehicle might be-
come a hazard to other traffic.
•Turn signals do not work when the haz-
ard warning flasher lights are on.
Some jurisdictions may prohibit the use of
the hazard warning flasher switch while
driving.If you have a flat tire, follow the instructions
in this section.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
WARNING
•If the low tire pressure warning light il-
luminates or a tire pressure-related
warning is displayed by the vehicle in-
formation display while driving, avoid
sudden steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop the
vehicle as soon as possible. Driving with
under-inflated tires may permanently
damage the tires and increase the likeli-
hood of tire failure. Serious vehicle dam-
age could occur and may lead to an acci-
dent and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the tire and loading informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a replacement tire as
soon as possible.

HAZARD WARNING FLASHER
SWITCHFLAT TIRE
6-2In case of emergency

•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. It is recommended you Con-
tact an INFINITI retailer as soon as pos-
sible for tire replacement and/or system
resetting.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•If you used Emergency Tire Sealant to
repair a minor tire puncture, the TPMS
sensor should be checked when repair-
ing or replacing the tire. It is recom-
mended you visit an INFINITI retailer for
this service.
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the
low tire pressure warning light is lit, and a tire
pressure-related warning (if equipped) ap-
pears in the vehicle information display, one
or more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light (in the meter panel). This system willactivate only when the vehicle is driven at
speeds above 16 MPH (25 km/h).
For more details about the TPMS, see "Tire
Pressure Monitoring System (TPMS)".
STOPPING VEHICLE

RUN-FLAT TIRES
With special run-flat tires, you can continue
to drive your vehicle even if there is a total
loss of pressure in one or more tires. The
affected tire must not show any clearly visible
damage.
You can recognize run-flat tires by the mark-
ing which appears on the tire side wall. You
will find this marking next to the tire size
designation, the load-bearing capacity and
the speed index.
Run-flat tires may only be used in conjunction
with an activated tire pressure loss warning
system or tire pressure monitor.
Pressure loss warning message
If a pressure loss warning message appears
in the vehicle information display:
•Observe the instructions in the display
messages.
•Check the tire for damage.
•If driving on, observe the following notes.
The driving distance possible in run-flat mode
is approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
20 miles (30 km) when the vehicle is fully laden.
NIC2686
6-4In case of emergency

In addition to the vehicle load, the driving
distance possible depends upon:
•Vehicle speed.
•Road condition.
•Outside temperature.
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure
loss warning appears in the vehicle informa-
tion display.
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 maneu-
vers, 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.

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 to "Tire
Pressure Monitoring System (TPMS)".

Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifica-
tions are shown on the F.M.V.S.S./
C.M.V.S.S. label or the Tire and Loading In-
formation label (if so equipped) under the
Cold Tire Pressure heading. The Tire and
Loading Information label is affixed to the
driver side center pillar. Tire pressures should
be checked regularly because:
•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 sud-
denly and cause an accident.
•The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S. S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on the
Tire and Loading Information label (if so
equipped). Do not load your vehicle be-
yond this capacity. Overloading your
vehicle may result in reduced tire life,
unsafe operating conditions due to pre-
mature tire failure, or unfavorable han-
dling characteristics and could also lead
to a serious accident. Loading beyond
the specified 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
pressure 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 Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
