2020 INFINITI QX80 Owner's Manual

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
SYSTEM (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 “Tire Pressure Low Add
Air” warning appears in the vehicle informa-
tion 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 lights, in-
dicator lights and audible reminders” (P.2-
11) and “Tire Pressure Monitoring System
(TPMS)” (P.5-5).
WARNING
. If the low tire pressure warning light
illuminates while driving, avoid sud-
den 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.
. Since the spare tire is not equipped
with the TPMS, 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. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may

back of the wheel diagonally opposite the
flat tire to prevent the vehicle from moving
when it is jacked up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.

WARNING
When removing jacking tools, be sure
the rubber sound suppressor, used to
control jack stand from rattling against
metal, is not attached to the jacking tool. If rubber sound suppressor remains on
jack when vehicle is being jacked up, the
vehicle will be unstable and may fall off
jack stand causing serious injury of
death.

as illustrated.
6. Fit the square end of the jack rod into the square hole of the wheel nut wrench to
form a handle
. 7. Locate the oval opening above the
middle of the rear bumper.
8. Place the T-shaped end of the jack rod through the opening and direct it to-
wards the spare wheel winch assembly,
located directly above the spare wheel.

CAUTION
Do not insert the jack rod straight as it is
designed to be inserted at an angle as
shown.
9. Seat the T-shaped end of the jack rod into the T-shaped opening of the spare
wheel winch. Apply pressure to keep the
jack rod engaged in the spare wheel
winch and turn the jack rod counter-
clockwise to lower the spare wheel.

10. Once the spare wheel is completelylowered, remove the jack rod and reach
under the vehicle to remove the hanging
plate.
11. Carefully slide the spare wheel from under the rear of the vehicle.
After preparing the spare tire, to remove the
rod, pull out the rod while moving the rod to
the right and left with the screw of the
extension facing the side.
CAUTION
When storing the wheel, make sure that
the hanging plate is in the center of the wheel and then lift it up into the storage
area.

Jacking up the vehicle and removing
the damaged tire
WARNING
.Never get under the vehicle while it is
supported only by the jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Use only the jack provided with your
vehicle to lift the vehicle. Do not use
the jack provided with your vehicle on
other vehicles. The jack is designed
for lifting only your vehicle during a
tire change.
. Use the correct jack-up points. Never
use any other part of the vehicle for
jack support.
. Never jack up the vehicle more than
necessary.
. Never use blocks on or under the jack. .
Do not start or run the engine while
vehicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicles with limited slip
differentials.
. Do not allow passengers to stay in
the vehicle while it is on the jack.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.SCE0875
Jack-up point
1. Place the jack directly under the jack-up points as illustrated.
The jack should be used on level firm
ground.

SCE0876
2. Loosen each wheel nut one or two turnsby turning counterclockwise with the
wheel nut wrench. Do not remove the
wheel nuts until the tire is off the
ground.

3. Install the assembled jack rod into the
jack as shown.
4. Carefully raise the vehicle until the clearance between the tire and ground
is achieved.
5. To lift the vehicle, securely hold the jack lever and rod with both hands and turn
the jack lever.
NOTE:
Before jacking up the vehicle, make sure the
ignition switch is placed in the OFF position.
If the vehicle is lifted up with the engine
running, the auto-leveling suspension will
become disabled after 120 seconds. To
reset the auto-leveling suspension, cycle

Installing the spare tire
The full-size temporary use only spare tire
(if so equipped) is designed for emergency
use. (See specific instructions under the
heading “Wheels and tires” (P.8-27).)
1. Clean any mud or dirt from the surfacebetween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence illustrated (
,,,,,)
until they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the wheel nut wrench, tighten the wheel
nuts securely in the sequence as illu-
strated. Lower the vehicle completely.
WARNING
.
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.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 specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD pressure.
