2021 INFINITI QX80 service indicator

5-94Starting and driving
Action to take:
When the conditions listed above are no
longer present, turn the system off with the
dynamic driver assistance switch
. Turn the
DCA system back on to use the system.
. If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104 °F (40 °C)) and then
started, the DCA system may be deacti-
vated automatically and the “Unavail-
able: High Accelerator Temperature”
message will appear in the vehicle in-
formation display for a period of time.
Action to take:
When the interior temperature is reduced,
turn on the DCA system again.
Condition B:
Under the following conditions, making it
impossible to detect a vehicle ahead, the
DCA system is automatically canceled.
The chime will sound, the DCA system
indicator (orange) will come on and the
“Not Available: Front Radar Blocked” warn-
ing message will appear in the vehicle
information display.
. When the radar sensor area of the front
bumper is covered with dirt or is ob-
structed Action to take:
If the DCA system indicator (orange) comes
on and the warning message appears, stop
the vehicle in a safe place, place the shift
lever in the P (Park) position and turn the
engine off. When the radar signal is tem-
porarily interrupted, clean the sensor area of
the front bumper and restart the engine. If
the warning message continues to be dis-
played, have the DCA system checked. It is
recommended you visit an INFINITI retailer
for this service.
.
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next
to long walls)
Action to take:
When the above conditions no longer exist,
turn the DCA system back on to use the
system.
SYSTEM MALFUNCTION
Condition:
When the DCA system is not operating
properly, the chime sounds and the system
warning message “Malfunction” will appear.
Action to take:
If the warning message appears, park the
vehicle in a safe place. Turn the engine off,
restart the engine, and turn on the DCA
system again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the
system is malfunctioning. Although the
vehicle is still driveable under normal con-
ditions, have the vehicle checked. It is
recommended you visit an INFINITI retailer
for this service.

If the 4WD warning light comes on, the
4WD shift indicator turns off.
High-temperature transfer case oil makes
the 4WD warning light blink rapidly (about
twice per second). If the warning light blinks
rapidly during operation, stop the vehicle in a
safe place immediately. Then if the light
turns off after a while, you can continue
driving.
A large difference between the diameters of
front and rear wheels will make the 4WD
warning light blink slowly (about once per
two seconds). Change the 4WD shift switch
to AUTO and do not drive fast.
CAUTION
.If the 4WD warning light comes on or
blinks slowly during operation or
rapidly after stopping the vehicle for
a while, have your vehicle checked as
soon as possible. It is recommended
you visit an INFINITI retailer for this
service.
. Shifting between 4HI and 4LO is not
recommended when the 4WD warn-
ing light turns on. .
When the 4WD warning light comes
on, the 2WD mode may be engaged
even if the 4WD shift switch is in
AUTO or 4H. Be especially careful
when driving. If corresponding parts
are malfunctioning, the 4WD mode
will not be engaged even if the 4WD
shift switch is shifted.
. Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces
in 4HI or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning light turns on
when driving on dry hard surface
roads:
— in the AUTO or 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
shift lever to the N (Neutral)
position and shift the 4WD shift
switch to AUTO.
. If the 4WD warning light is still on
after the above operation, have your
vehicle checked as soon as possible. It
is recommended you visit an INFINITI
retailer for this service. .
The transfer case may be damaged if
you continue driving with the warn-
ing light blinking.

Check the fluid level in each cell (Remove the
battery cover if it is necessary). It should be
between the UPPER LEVEL
and LOWER
LEVELlines.
If it is necessary to add fluid, add only
distilled water to bring the level to the
indicator in each filler opening. Do not
overfill.

1. Remove the cell plugs.
2. Add distilled water up to the UPPER LEVEL
line.
If the side of the battery is not clear,
check the distilled water level by looking
directly above the cell; the condition
indicates OK and the conditionsneeds
more to be added.
3. Tighten cell plugs
.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, see “Jump
starting” (P.6-11). If the engine does not
start by jump starting, the battery may have
to be replaced. It is recommended you visit
an INFINITI retailer for this service.

tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
commended you visit an
INFINITI retailer for this ser-
vice.
. For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. (See “Speci-
fications” (P.10-8) for recommended types
and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted or radial), or
tread patterns can adversely affect
the ride, braking, handling, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects may
lead to accidents and could result in
serious personal injury.
. For Two-Wheel Drive (2WD) models,
if your vehicle was originally
equipped with 4 tires that were the
same size and you are only replacing
2 of the 4 tires, install the new tires
on the rear axle. Placing new tires on
the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and
personal injury. .
If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
9) for wheel off-set dimensions.
. 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.
. The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
. When replacing the TPMS sensor, the
ID registration may be required. It is
