2014 INFINITI QX80 spare tire location

2-16Instruments and controls
Low tire pressure warning:
If the vehicle is being driven with low tire
pressure, the warning light will illuminate.
A CHECK TIRE PRESSURE warning also
appears in the dot matrix liquid crystal
display. If you select the tire pressure
information in the display, the LOW PRES-
SURE information will be displayed. The
tire pressure for each tire will also be
displayed.
When the low tire pressure warning light
illuminates, you should stop and adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire and
Loading Information label. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is
adjusted. After the tire is inflated to the
recommended pressure, the vehicle must
be driven at speeds above 16 MPH (25
km/h) to activate the TPMS and turn off the
low tire pressure warning light. Use a tire
pressure gauge to check the tire pressure.
The CHECK TIRE PRESSURE warning ap-
pears each time the ignition switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.For additional information, see
“Dot matrix
liquid crystal display” later in this section,
“Tire Pressure Monitoring System (TPMS)”
in the “5. Starting and driving” section and
“Tire Pressure Monitoring System (TPMS) ”
in the “6. In case of emergency” section.
TPMS malfunction:
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is pushed ON. The light will remain
on after 1 minute. Have the system
checked by an INFINITI retailer. The CHECK
TIRE PRESSURE warning does not appear if
the low tire pressure warning light illumi-
nates to indicate a TPMS malfunction.
For additional information, see “Tire Pres-
sure Monitoring System (TPMS)” in the“5.
Starting and driving” section.
WARNING
.If the light does not illuminate with the
ignition switch pushed ON, have the
vehicle checked by an INFINITI retailer as
soon as possible.
. If the light illuminates or LOW PRESSURE
information is displayed on the monitor screen 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 likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
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 Information
label to turn the low tire pressure
warning light OFF. If the light still
illuminates while driving after adjusting
the tire pressure, a tire may be flat. If
you have a flat tire, replace it with a
spare tire as soon as possible.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.

Additional information
.The TPMS does not monitor the tire
pressure of the spare tire.
. 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).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is
inflated to the recommended pressure,
the vehicle must be driven at speeds
above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
. The CHECK TIRE PRESSURE warning
appears in the dot matrix liquid crystal
display when the low tire pressure
warning light is illuminated and low
tire pressure is detected. The CHECK
TIRE PRESSURE warning turns off when
the low tire pressure warning light
turns off.
The CHECK TIRE PRESSURE warning
appears each time the ignition switch
is placed in the ON position as long as the low tire pressure warning light
remains illuminated.
The CHECK TIRE PRESSURE warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
. Tire pressure rises and falls depending
on the heat caused by the vehicle’s
operation and the outside temperature.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If
the warning light illuminates in low
ambient temperature, check the tire
pressure for all four tires.
. You can also check the pressure of all
tires (except the spare tire) on the
display screen. The order of the tire
pressure figures displayed on the
screen does not correspond with the
actual order of the tire position. See
“TIRE PRESSURE information” in the“4.
Monitor, climate, audio, phone and
voice recognition systems” section.
For additional information, see “Low tire
pressure warning light” in the“2. Instru-
ments and controls” section and“Tire Pressure Monitoring System (TPMS)
”in
the “6. In case of emergency” section.

LANE DEPARTURE PREVENTION
(LDP) SYSTEM
Precautions on LDP system
WARNING
.The LDP system will not steer the vehicle
or prevent loss of control. It is the
driver’s responsibility to stay alert, drive
safely, keep the vehicle in the traveling
lane, and be in control of vehicle at all
times.
. The LDP 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
conditions.
. Using the LDP system under some
conditions of road, lane marker or
weather, or when you change lanes
without using the lane change signal
could lead to an unexpected system
operation. In such conditions, you need
to correct the vehicle’s direction with
your steering operation to avoid acci-
dents. .
When the LDP system is operating, avoid
excessive or sudden steering maneu-
vers. Otherwise, you could lose control
of the vehicle.
. The LDP system will not operate at
speeds below approximately 45 MPH
(70 km/h) or if it cannot detect lane
markers.
. The LDP system may not function
properly under the following conditions,
and do not use the LDP system:
—During bad weather (rain, fog, snow,
wind, etc.).
—When driving on slippery roads,
such as on ice or snow, etc.
—When driving off-road such as on sand or rock, etc.
—When driving on winding or uneven
roads.
—When there is a lane closure due toroad repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane width is too narrow.
—When driving without normal tireconditions (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.
—When towing a trailer or othervehicle.
. If the LDP system malfunctions, it will
cancel automatically. The lane departure
warning light (orange) on the instrument
panel will illuminate.
. If the lane departure warning light
(orange) illuminates, pull off the road
to a safe location and stop the vehicle.
Turn the engine off and restart the
engine. If the warning light (orange)
continues to illuminate, have the LDP
system checked by an INFINITI retailer.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
The functions of the LDP system (warning
and brake control assist) may or may not
operate properly under the following con-
ditions:

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds.TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears in the dot
matrix liquid crystal 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 warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see
“Warning/indicator lights and audible re-
minders” in the“2. Instruments and
controls” section,“TIRE PRESSURE infor-
mation” in the“4. Monitor, climate, audio,
phone and voice recognition systems”
section and “Tire Pressure Monitoring
System (TPMS)” in the“5. Starting and
driving” section.
WARNING
.If the low tire pressure warning light
illuminates or LOW PRESSURE informa- tion is displayed on the monitor screen
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 likelihood of tire fail-
ure. Serious vehicle damage could occur
and may lead to an accident 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 Information label to turn
the low tire pressure warning light OFF. If
the light still illuminates while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire,
replace it with a spare tire as soon as
possible.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.

TIRE CHAINS
Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions. Use only SAE
Class S chains. Class“S”chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the
tire chain 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 addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling and performance may be adversely af-
fected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on the full-size
temporary use only spare tire (if so
equipped).
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.

CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires in accordance with the main-
tenance log shown in the
“INFINITI
Service and Maintenance Guide” .
(See “Flat tire” in the“6. In case of
emergency” section for tire replacing
procedures.)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Wheel nut tightening torque:98 ft-lb (133 N·m)
The wheel nuts must be kept tigh-
tened to the specification at all
times. It is recommended that wheel
nuts be tightened to the specifica-
tion at each tire rotation interval.
WARNING
. After rotating the tires, check and
adjust the tire pressure.
. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
. Do not include the full-size tem-
porary use only spare tire (if so
equipped) in the tire rotation.
