spare wheel INFINITI QX30 2018 Owner's Manual

•The system will not operate at speeds be-
low approximately 40 MPH (60 km/h) or
if it cannot detect lane markers.
•The LDW system is primarily intended
for use on well-developed freeways or
highways. It may not detect the lane
markers in certain roads, weather or
driving conditions.
•Do not use the LDW system under the
following conditions as it may not func-
tion 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 tem-
porary lane.
–When driving on roads where the lane
width is too narrow.
–When driving without normal tire
conditions (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 suspen-
sion parts.
•The camera may not detect lane markers
in the following situations and the LDW
system may not operate properly.
–On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-
standard lane markers; or lane mark-
ers 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
contrasting objects, such as shad-
ows, 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 direc-
tion 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
camera unit. (For example, the light
directly shines on the front of the ve-
hicle at sunrise or sunset.)
–When a sudden change in brightness
occurs. (For example, when the ve-
hicle enters or exits a tunnel or under
a bridge.)
–When there is poor visibility. (For ex-
ample, due to insufficient illumina-
tion of the road, or due to snow, rain,
fog or spray.
–When there is glare. (For example,
from oncoming traffic, the sun or re-
flection when the road is wet).
5-34Starting and driving

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.
REMOVING AND FITTING
WHEELS
NOTE
A spare wheel is not provided with your ve-
hicle.
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 be-
hind the wheel diagonally opposite the flat
tire
Ato prevent the vehicle from moving
when it is on the jack.

7. Carefully raise the vehicle until the tire
clears the ground.
8. Remove the wheel bolts, then remove the
wheel with the flat tire.
WARNING
The wheel is heavy. Be sure that your feet
are 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 be-
come 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.

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 sur-
face horizontally 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 se-
quence as illustrated (

TYPES OF TIRES
WARNING
•When changing or replacing tires, be
sure all four tires are of the same type
(i.e, summer, 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 po-
tential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
•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 be-
tween tires on the front and rear axles
which can cause the Vehicle Dynamic
Control (VDC) system to malfunctionresulting in personal injury or death, ex-
cessive tire wear and may damage the
transmission, transfer case and differ-
ential gears.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation“ (Canada) in the Warranty In-
formation 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 necessary. 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 seasontires 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 sub-
stantially reduced 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 han-
dling of your vehicle.
Generally, snow tires have lower speed rat-
ings 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
8-32Do-it-yourself

installing studded tires. Skid and traction ca-
pabilities 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 necessary. 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.
Installation 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 accord-
ing to location. Check the local laws before
installing 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 in-
structions.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. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle 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
various 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 visible, the tire should be replaced.

•Tires degrade with age and use. Have
tires, including the spare, over 6 years
old checked by a qualified technician be-
cause some tire damage may not be ob-
vious. Replace the tires as necessary to
prevent tire failure and possible per-
sonal injury.
•Improper service of the spare tire may
result in serious personal injury. If it is
necessary to repair the spare tire, it is
recommended that you visit an INFINITI
retailer for this service.
•For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.

Improper servicing of a tire may result in se-
rious personal injury. If it is necessary to re-pair a tire, it is recommended you contact an
INFINITI retailer.
TIRE ROTATION
INFINITI recommends rotating the tires ev-
ery 5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer to "Flat tire".As soon as
possible, tighten the wheel nuts to the speci-
fied torque with a torque wrench.
Wheel nut tightening torque: 96 ft-lb
(130 N·m)
The wheel nuts must be kept tightened to
specifications 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 ad-
just the tire pressure.
•Do not include the spare tire in the tire
rotation.
•For additional information regarding
tires, refer to "Important Tire Safety
Information" (US) or "Tire Safety Infor-
mation" in the Warranty 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. (See "Wheels and Tires"
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 de-
creased braking efficiency and/or early brake
pad/shoe wear.
Confirm the following for the TPMS:
WARNING
•The use of tires other than those recom-
mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
