spare tire INFINITI QX30 2017 Owners Manual

CAUTION
•Do not use leaded gasoline. (SeeRecom-
mended fluids/lubricants and capacitiesin
the9. Maintenance and Schedulessec-
tion.) Deposits from leaded gasoline seri-
ously reduce the ability of the three-way
catalyst to help reduce exhaust pollutants
and/or damage the three-way catalyst.
•Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems may cause overrich fuel to flow into
the three-way catalyst, causing it to over-
heat. Do not keep driving if the engine mis-
fires, or if noticeable loss of performance or
other unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended you visit an
INFINITI retailer for this service.
•Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-way
catalyst.
•Do not race the engine while warming it up.
•Do not push or tow your vehicle to start the
engine.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
Each tire, including the spare (if present),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS malfunc-
tion indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from working properly. Always check
the TPMS telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
The vehicle’s wheels have sensors fitted that
monitor the tire pressures in all four tires The
tire pressure monitor warns you if the pressure
drops in one or more of the tires The tire
pressure monitor only functions if the corre-
sponding sensors are fitted to all wheels.
Information on tire pressures is shown in the
vehicle information display. After a few minutes
of driving, the current tire pressure of each tire
is shown in the [Serv.] menu of the vehicle
information display.

•The LDW system is primarily intended for
use on well-developed freeways or high-
ways. It may not detect the lane markers in
certain roads, weather or driving condi-
tions.
•Do not use the LDW system under the fol-
lowing conditions as it may not function
properly:
–During bad weather (rain, fog, snow,
etc.).
–When driving on slippery roads, such as
on ice or snow, etc.
–When driving on winding or uneven
roads.
–When there is a lane closure due to road
repairs.
–When driving in a makeshift or tempo-
rary lane.
–When driving on roads where the lane
width is too narrow.
–When driving without normal tire condi-
tions (for example, tire wear, low tire
pressure, installation of spare tire, tire
chains, non-standard wheels).
–When the vehicle is equipped with non-
original brake parts or suspension parts.
•The camera may not detect lane markers in
the following situations and the LDW sys-
tem may not operate properly.
–On roads where there are multiple par-
allel lane markers; lane markers that are
faded or not painted clearly; yellow
painted lane markers; non-standard lane
markers; or lane markers covered with
water, dirt, snow, etc.
–On roads where the discontinued lane
markers are still detectable.
–On roads where there are sharp curves.
–On roads where there are sharply con-
trasting objects, such as shadows,
snow, water, wheel ruts, seams or lines
remaining after road repairs. (The LDW
system could detect these items as lane
markers.)
–On roads where the traveling lane
merges or separates.
–When the vehicle’s traveling direction
does not align with the lane marker.
–When traveling close to the vehicle in
front of you, which obstructs the lane
camera unit detection range.
–When rain, snow or dirt adheres to the
windshield in front of the lane camera
unit.–When the headlights are not bright due
to dirt on the lens or if the aiming is not
adjusted properly.
–When strong light enters the lane cam-
era unit. (For example, the light directly
shines on the front of the vehicle at sun-
rise or sunset.)
–When a sudden change in brightness
occurs. (For example, when the vehicle
enters or exits a tunnel or under a
bridge.)
–When there is poor visibility. (For ex-
ample, due to insufficient illumination of
the road, or due to snow, rain, fog or
spray.
–When there is glare. (For example, from
oncoming traffic, the sun or reflection
when the road is wet).
5-32Starting and 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

clear of the wheel and use gloves as necessary
to avoid injury.
Installing the wheel
WARNING
•A temporary use spare wheel and tire is
designed for emergency use.
•Never use wheel bolts other than those
provided with your vehicle. Incorrect wheel
bolts or improperly tightened wheel bolts
may cause the wheel to become loose or
come off. This could cause an accident.
•Never use oil or grease on the wheel bolts.
This may cause the wheel bolts to become
loose.ATighten
BLoosen
1. Clean any mud or dirt from the surface
between the wheel and the hub.
2. Carefully fit the wheel and tighten the wheel
bolts with your fingers. Check that all the
wheel bolts contact the wheel surface hori-
zontally and on the bevelled side.
Models with wheel lock bolt (if equipped):
Insert the wheel lock key into the wheel lock
bolt and tighten into the wheel finger tight.
3. With the wheel wrench, tighten the wheel
bolts alternately and evenly in the sequence

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.

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.

•Always use tires of the same type, size,
brand, construction 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 can cause the
Vehicle Dynamic Control (VDC) system to
malfunction resulting in personal injury or
death, excessive tire wear and may damage
the transmission, transfer case and differ-
ential gears.
•For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information“ (Canada)
in the Warranty Information Booklet.
CAUTION
ONLY use spare tires specified for the 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 nec-
essary. 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.
Summer tires
INFINITI specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced in snow and ice. Summer tires do not
have the tire traction rating M&S on the tire
sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use of
snow or all season tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating to
the original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.Generally, snow tires have lower speed ratings
than factory equipped tires and may not match
the potential maximum vehicle speed. Never
exceed the maximum speed rating of the tire. If
you install snow tires, they must be the same
size, brand, construction and tread pattern on
all four wheels.
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 capa-
bilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Four-Wheel Drive (4WD) models
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 nec-
essary. It is recommended that you visit an
INFINITI retailer.

TIRE CHAINS
CAUTION
Tire chains/cables should not be installed on
235/45 R19 or 235/50 R18 size tires. Installa-
tion of the tire chains/cables on 235/45 R19 or
235/50 R18 size tires will cause damage to the
vehicle. If you plan to use tire chains/cables,
you should install 215/60 R17 size tires on your
vehicle.
Use of tire chains may be prohibited according
to location. Check the local laws before install-
ing tire chains. When installing tire chains,
make sure that they are of 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 un-
derbody. If possible, avoid fully loading your
vehicle when using tire chains. In addition,
drive at a reduced speed. Otherwise, your ve-
hicle may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the front
wheels and not on the rear wheels.Never install tire chains on a T-type spare tire
(TEMPORARY USE ONLY).
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains in
such conditions can cause damage to the vari-
ous mechanisms of the vehicle due to some
overstress.

TIRE WEAR AND DAMAGE
WARNING
•Tires should be periodically inspected for
wear, cracking, bulging or objects caught in
the tread. If excessive wear, cracks, bulging
or deep cuts are found, the tire should be
replaced immediately.
•The original tires have a built-in tread wear
indicator. When the wear indicator is vis-
ible, the tire should be replaced.
SDI1663Z

•Tires degrade with age and use. Have tires,
including the spare, over 6 years old
checked by a qualified technician because
some tire damage may not be obvious. Re-
place the tires as necessary to prevent tire
failure and possible personal injury.
•Improper service of the spare tire may re-
sult in serious personal injury. If it is neces-
sary to repair the spare tire, it is recom-
mended that you visit an INFINITI retailer for
this service.
•For additional information regarding tires,
refer to “Important Tire Safety Information”

excessive wear, cracks, bulging or deep cuts are
found, the tire should be replaced immediately.
The original tires have a built-in tread wear
indicator. When the wear indicator is visible,
the tire should be replaced.
Improper servicing of a tire may result in seri-
ous personal injury. If it is necessary to repair a
tire, it is recommended you contact an INFINITI
retailer.
TIRE ROTATION
INFINITI recommends rotating the tires every
5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer toFlat tirein the6. In case
of emergencysection.As soon as possible,
tighten the wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 96 ft-lb (130 N·m)
The wheel nuts must be kept tightened to speci-
fications at all times. It is recommended that
wheel nuts be tightened to specification at each
tire rotation interval.
WARNING
•After rotating the tires, check and adjust
the tire pressure.
•Do not include the spare tire in the tire
rotation.
•For additional information regarding tires,
refer toImportant Tire Safety Information
(US) orTire Safety Informationin the War-
ranty Information Booklet.
REPLACING WHEELS AND TIRES
WARNING
Do not install a deformed wheel or tire even if it
has been repaired. Such wheels or tires could
have structural damage and could fail without
warning.
When replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. (SeeWheels and Tiresin the9.
Maintenance and SchedulesMaintenance and
Schedulessection for recommended types and
sizes of tires and wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to decreased
braking efficiency and/or early brake pad/shoe
wear.
