wheel INFINITI QX80 2019 Service Manual

cause injury to you or your passen-
gers.
. To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so
equipped) and evenly distribute the
load. Secure heavy loads in the cargo
area as far forward and as low as
possible. Do not equip the vehicle
with tires larger than specified in this
manual. This could cause your vehicle
to roll over.
. Do not grip the inside or spokes of the
steering wheel when driving off-
road. The steering wheel could move
suddenly and injure your hands. In-
stead drive with your fingers and
thumbs on the outside of the rim.
. Before operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
. Always drive with the floor mats in
place as the floor may became hot.
. Lower your speed when encountering
strong crosswinds. With a higher
center of gravity, your INFINITI is
more affected by strong side winds.
Slower speeds ensure better vehicle
control. .
Do not drive beyond the performance
capability of the tires, even with
4WD engaged.
. For 4WD equipped vehicles, do not
attempt 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 drivetrain 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 dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing), or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury (4WD models).
. When a wheel is off the ground due
to an unlevel surface, do not spin the
wheel excessively. .
Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
. If at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your vehicle has a higher
center of gravity than a conventional
passenger car. The vehicle is not
designed for cornering at the same
speeds as conventional passenger
cars. Failure to operate this vehicle
correctly could result in loss of con-
trol and/or a rollover accident.
. Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
. Be sure to check the brakes immedi-
ately after driving in mud or water.
See “Brake system” (P.5-131) for wet
brakes.
. Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
. Whenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent
maintenance may be required. See
Starting and driving5-11

5-12Starting and driving
the maintenance schedules shown in
the "9. Maintenance and schedules"
section.
. Spinning the rear wheels on slippery
surfaces may cause the 4WD warn-
ing light to flash. The 4WD system
may also automatically switch from
the 4WD mode to the 2WD mode.
This could reduce traction. Be espe-
cially careful when towing a trailer
(4WD models).WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop
when the ignition switch is pushed 3
consecutive times or the ignition switch
is pushed and held for more than 2
seconds.) If the engine stops while the
vehicle is being driven, this could lead to
a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the shift lever to the
P (Park) position.

Manual shift mode
When the shift lever is in the manual shift
gate, the transmission is ready for the
manual shift mode. Shift ranges can be
selected manually by moving the shift lever
up or down.
When shifting up, move the shift lever to the
+ (up) side. The transmission shifts to the
higher range.
When shifting down, move the shift lever to
the − (down) side. The transmission shifts to
the lower range.
When canceling the manual shift mode,
return the shift lever to the D (Drive)
position. The transmission returns to the
normal driving mode.
In the manual shift mode, the shift range is
displayed on the position indicator in the
meter.
Shift ranges up or down one by one as
follows:
M1?
/M2 ?
/M3?
/M4 ?
/M5?
/M6?
/M7
M7 (7th):
Use this position for all normal forward
driving at highway speeds.
M6 (6th) andM5 (5th):
Use these positions when driving up long
slopes, or for engine braking when driving
down long slopes.
M4 (4th),M3 (3rd) andM2 (2nd):
Use these positions for hill climbing or engine
braking on downhill grades.
M1 (1st):
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
or for maximum engine braking on steep
downhill grades.
. Remember not to drive at high speeds for
extended periods of time in lower than
7th gear. This reduces fuel economy.
. Moving the shift lever rapidly to the same
side twice will shift the ranges in succes-
sion.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
. When the transmission does not shift to
the selected gear, the Automatic Trans-
mission (AT) position indicator light (in
the vehicle information display) will
blink and the buzzer will sound. .
In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a stop.
When accelerating again, it is necessary
to shift up to the desired range.
Accelerator downshift — In D (Drive)
position —
For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear,
depending on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, note
that the transmission will be locked in any of
the forward gears according to the condi-
tion.
If the vehicle is driven under extreme
conditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, push the switch to the
OFF position and wait for 3 seconds. Then
push the ignition switch back to the ON
position. The vehicle should return to its
normal operating condition. If it does not
return to its normal operating condition,
have the transmission checked and re-
paired, if necessary. It is recommended you

.Lane Departure Warning (LDW) system
— warns the driver with a warning light and chime that the vehicle is begin-
ning to leave the driving lane.
. Lane Departure Prevention (LDP) system
— warns the driver with a warning light and chime, and helps assist the driver
to return the vehicle to the center of
the traveling lane by applying the
brakes to the left or right wheels
individually (for a short period of
time).
JVS1142X
The LDW and LDP systems use a camerainstalled behind the windshield to monitor
the lane markers of your traveling lane.

2. Touch [Driver Assistance].
3. Touch [Lane Assist].
4. Touch [Lane Departure Warning] to turn the system ON/OFF.
LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 45 MPH (70 km/h) and the lane
markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the LDW
indicator light (orange) on the instrument
panel will flash and a warning chime will
sound. Then, the LDP system will automa-
tically apply the brakes for a short period of
time to help assist the driver to return the
vehicle to the center of the traveling lane.
NOTE:
.The LDP system is not designed to work
when you operate the lane change signal
and change traveling lanes in the direc-
tion of the signal. (The LDP system will
become operable again approximately 2
seconds after the lane change signal is
turned off.)
. The LDP braking assist will not operate
or will stop operating and only a warn-
ing chime will sound under the following
conditions.
— When the brake pedal is depressed.
— When the steering wheel is turned as
far as necessary for the vehicle to
change lanes.
— When the accelerator pedal is de-
pressed while brake control assist is provided.
— When the Intelligent Cruise Control
(ICC), Distance Control Assist (DCA),
Blind Spot Intervention (BSI), Blind
Spot Warning (BSW), Predictive For-
ward Collision Warning (PFCW) or
Forward Emergency Braking (FEB)
warnings sound.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
. While the LDP system is operating, you
may hear a sound of brake operation.
This is normal and indicates that the
LDP system is operating properly.

LDW/LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the LDW and LDP systems. Failure to
operate the vehicle in accordance with
these system limitations could result in
serious injury or death.
.The system will not operate at speeds
below 45 MPH (70 km/h) or if it
cannot detect lane markers.
. The LDP system is primarily intended
for use on well-developed freeways
or highways. It may not detect the
lane markers in certain roads, weath-
er or driving conditions.
. Do not use the LDP system under the
following 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 un- even roads.
— When there is a lane closure due to road repairs. — When driving in a makeshift or
temporary 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-stan-
dard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts.
— When you are towing a trailer or other vehicle.
. The camera may not detect lane
markers in the following situations
and the LDW and LDP systems may
not operate properly.
— On roads where there are multi- ple parallel 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 sharplycontrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs. (The LDW and LDP
systems could detect these items
as lane markers.)
— On roads where the traveling lane merges or separates.
— When the vehicle’s traveling di- rection does not align with the
lane marker.
— When traveling close to the ve- hicle in front of you, which ob-
structs 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 vehicle at sunrise or sun-
set.) — When a sudden change in bright-
ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
