2017 INFINITI QX30 tire size

•Avoid parking your vehicle on steep hills. If
you get out of the vehicle and it rolls for-
ward, backward or sideways, you could be
injured.
•Whenever you drive off-road through sand,
mud or water as deep as the wheel hub,
more frequent maintenance may be re-
quired. For additional information, refer to
Maintenance schedulesin the
9. Maintenance and Schedules section.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS (IF SO
EQUIPPED)
WARNING
•Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Install tire chains on the front wheels when
driving on slippery roads and drive care-
fully.
•This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
•For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any D (Drive) or R (Re-
verse) position with the engine running. Do-
ing so may result in drivetrain damage or
unexpected vehicle movement which could
result in serious vehicle damage or personal
injury
•Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer, (such
as the dynamometers used by some states
for emissions testing), or similar equipment
even if the other two wheels are raised off
the ground. Make sure you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in se-
rious vehicle damage or personal injury.
•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively. The INFINITI Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll road
device or automated payment device on the key
ring. Restart the engine using the following
procedures:
1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK position and wait approximately 5 seconds.
3. Repeat Step 1 and 2 again.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices.

6.Avoid Idling
•Shutting off your engine when safe for
stops exceeding 30 seconds saves fuel
and reduces emissions.
7. Buy an Automated Pass for Toll Roads
•Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
8. Winter Warm Up
•Limit idling time to minimize impact to
fuel economy.
•Vehicles typically need no more than 30
seconds of idling at start-up to effectively
circulate the engine oil before driving.
•Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
9. Keeping your Vehicle Cool
•Park your vehicle in a covered parking
area or in the shade whenever possible.
•When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system.
•Keep your engine tuned up.
•Follow the recommended scheduled mainte-
nance.
•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 in
the 10. Technical information section
WARNING
•Do not drive beyond the performance capa-
bility of the tires, even with 4WD engaged.
Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause loss
of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
•For 4WD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any drive or reverse po-
sition with the engine running. Doing so
may result in drivetrain damage or unex-
pected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
•Do not attempt to test a 4WD equipped ve-
hicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
even if the other two wheels are raised off
the ground. Make sure that you inform the
test facility personnel that your vehicle is

slight pulsation. This is normal and indicates
that the Brake Assist System is operating (if
equipped).
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out
the brake linings/pads faster, and increase fuel
consumption.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or acceleration could cause the
wheels to skid and result in an accident.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly depressing the brake pedal
to heat up the brakes. Do this until the brakesreturn to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.
Driving uphill
When starting on a steep gradient, it is some-
times difficult to operate the brake. Use the
parking brake to hold the vehicle. When ready
to start, make sure that the shift lever is in an
appropriate forward or reverse driving position,
release the parking brake while depressing the
accelerator pedal. If your vehicle has an electric
parking brake, this will automatically release
when you depress the accelerator pedal (DCT
models).
Driving downhill
The engine braking action is effective for con-
trolling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine braking,
should be selected.
Parking brake break-in
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
The Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent acci-
dents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on normal
surfaces even with ABS. Stopping distances
may also be longer on rough, gravel or snow
covered roads, or if you are using tire chains.
Always maintain a safe distance from the ve-
hicle in front of you. Ultimately, the driver is
responsible for safety.
Tire type and condition may also affect braking
effectiveness.
– When replacing tires, install the specified
size of tires on all four wheels.
– When installing a replacement tire, make sure
that it is the proper size and type as specified
on the tire and loading information label. (See
5-88Starting and driving

coolantin the8. Do-it-yourself section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, INFINITI recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. It is rec-
ommended that you visit an INFINITI retailer
for the tire type, size, speed rating and
availability information.
2. For additional traction on icy roads, studded tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded snow
tires, on wet or dry surfaces, may be poorer than
that of non-studded snow tires.
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 possibil-
ity of whipping action damage to the fenders
or underbody. In addition, drive at a reduced
speed, otherwise, your vehicle may be dam-
aged and/or vehicle handling and perfor-
mance may be adversely 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 remove
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 snowdrifts.
•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 caution.
Accelerate and slow down with care. If ac-
celerating 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 slip-
pery 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 un-
der your vehicle. Keep snow clear of the
exhaust pipe and from around your 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 recognise run-flat tires by the marking
which appears on the tire side wall. You will
find this marking next to the tire size designa-
tion, 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 mes-
sages.
•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 ve-
hicle 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 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.

Tire and Loading Information label
1Seating capacity: The maximum number of
occupants that can be seated in the vehicle.
2Vehicle load limit: See Vehicle loading
information in the10. Technical informa-
tion section.
3Original size: The size of the tires originally
installed on the vehicle at the factory.
4Cold tire pressure: Inflate the tires to this
pressure when the tires are cold. 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.
The recommended cold tire inflation is set
by the manufacturer to provide the best
balance of tire wear, vehicle handling,
driveability, tire noise, etc., up to the vehi-
cle’s GVWR.

TIRE INFLATION PRESSURE
Checking tire pressure
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely onto thevalve 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
leakage.
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.

TIRE LABELING
Federal law requires tire manufacturers to place
standardized information on the sidewall of all
tires. This information identifies and describes
the fundamental characteristics of the tire and
also provides the tire identification number
(TIN) for safety standard certification. The TIN
can be used to identify the tire in case of a
recall.
