2018 INFINITI QX30 tire pressure

•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

CAUTION
Do not drive over obstacles such as curbs,
as you may damage the wheels or tires.
IPA may also display spaces not suitable for
parking, for example:
•Parking or stopping prohibition.
•In front of driveways or entrances and
exits.
•Unsuitable surfaces.
Parking tips:
•On narrow roads, drive as closely as pos-
sible past the parking space.
•Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
•Parking spaces that are partly occupied by
trailer towing bars might not be identified
as such or be measured incorrectly.
•Snowfall or heavy rain may lead to a park-
ing space being measured inaccurately.
•Pay attention to the sonar function warn-
ing messages during the parking proce-
dure.
•You can intervene in the steering proce-
dure to correct it at any time. IPA will then
be canceled.
•When transporting a load which protrudes
from your vehicle, you should not use IPA.
•Never use IPA when snow chains are fit-
ted.
•Make sure that the tire pressures are al-
ways correct. This has a direct influence on
the parking characteristics of the vehicle.
Use IPA for parking spaces that are:
•Parallel or at right angles to the direction
of travel.
•On straight roads, not bends.
•On the same level as the road, e. g. not on
the sidewalk.
For vehicles with the towbar folded out, the
minimum length for parking spaces is slightly
longer.
If you have attached a trailer to your vehicle,
you may not use IPA. Once the electrical
connection is established between your ve-
hicle and the trailer, IPA is no longer available.
The sonar function is deactivated for the rear
area
DETECTING PARKING SPACES
The IPA system can only be used to park in
spaces that have vehicles directly on either
side of the parking space.
Objects located above the height range of
IPA will not be detected when the parking
space is measured. These are not taken into
account when the parking procedure is calcu-
lated, e. g. overhanging loads, tail sections or
loading ramps of goods vehicles.
WARNING
If there are objects above the detection
range, IPA may steer too early. This could
cause a collision. There is a risk of an acci-
dent.
If objects are located above the detection
range, stop and switch off the IPA.
For further information on the detection
range see "Range of the sensors" later in this
section.
Starting and driving5-71

•Keep your engine tuned up.
•Follow the recommended scheduled
maintenance.
•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"
WARNING
•Do not drive beyond the performance
capability of the tires, even with 4WD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), 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 at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test a 4WD 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 that you inform the test facility
personnel that your vehicle is equipped
with 4WD before it is placed on a dyna-
mometer. Using the wrong test equip-
ment may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.
INCREASING FUEL ECONOMY FOUR-WHEEL DRIVE (4WD) (IF
EQUIPPED)
5-86Starting and driving

•Do not place the ignition switch in the on
position while the steering wheel or a
tire is removed.
•Do not turn the steering wheel as much
as possible while the ignition switch is in
any position other than the ON position.
•Installing an accessory on the steering
wheel, or changing the steering wheel,
may reduce the steering performance.
NOTE
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assistance for
the steering wheel will be reduced. This is to
prevent overheating of the electric power
steering system and protect it from becom-
ing damaged. While the power assistance is
reduced, steering wheel operation will be-
come heavy. When the temperature of the
electric power steering system decreases,
the power assistance level will return to nor-
mal. Avoid repeating such steering wheel
operations that could cause the electric
power steering system to overheat.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking ability at two wheels.
BRAKE PRECAUTIONS
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.
Vacuum assisted brakes
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle. The stopping distance will be longer.
WARNING
•If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
•Do not coast with the engine stopped.When the brake pedal is depressed slowly
and firmly, you may hear a clicking noise and
feel a slight pulsation. This is normal and
indicates that the Brake Assist System is op-
erating (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

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.
NIC2621
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.
