turn signal INFINITI QX80 2021 Service Manual

When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are
missing, and check for any loose wheel nuts.
Tighten if necessary.
Tire rotation*: Rotate tires at the specified
interval shown in the maintenance schedule.
Tires*: Check the pressure with a gauge
often and always prior to long distance trips.
If necessary, adjust the pressure in all tires,
including the spare, to the pressure speci-
fied. Check carefully for damage, cuts or
excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to wear
or age.
Wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect
uneven or abnormal tire wear, there may be
a need for wheel alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other damage.
Have a damaged windshield repaired by a
qualified repair facility. It is recommended
that you have a damaged windshield re-
paired by an INFINITI retailer, or an INFINITI
Certified Collision Center. To locate a colli-
sion center in your area, refer to http://
collision.infinitiusa.com.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning
the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your vehicle is held securely with the shift lever in
the P (Park) position without applying any
brakes.
Brake pedal:
Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, have your vehicle checked immediately.
It is recommended you visit an INFINITI
retailer for this service. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, it is recommended you
visit an INFINITI retailer for this service.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjuster and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position. Check
that the head restraints/headrests move up
and down smoothly and that the locks (if so

Trailer lights
Your vehicle is equipped with a towing
package, which also includes the 7-pin trailer
harness connector located under the trailer
hitch cover on the rear bumper.
CAUTION
.When splicing into the vehicle elec-
trical system, a commercially avail-
able power-type module/converter
must be used to provide power for
all trailer lighting. This unit uses the
vehicle battery as a direct power
source for all trailer lights while using the vehicle tail light, stoplight and
turn signal circuits as a signal source.
The module/converter must draw no
more than 15 milliamps from the stop
and tail lamp circuits. Using a mod-
ule/converter that exceeds these
power requirements may damage
the vehicle’s electrical system. See a
reputable trailer retailer to obtain the
proper equipment and to have it
installed.
. Do not connect electrical devices that
draw more than 40 amps to the
vehicle. The fusible link may melt.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, contact an INFINITI
retailer or reputable trailer retailer.
Trailer brakes
When towing a trailer load of 3,500 lbs.
(1,587 kg) or more, trailers with a brake
system MUST be used. However, most
states require a separate braking system on
trailers with a loaded weight above a
specific amount. Make sure the trailer meets
the local regulations and the regulations
where you plan to tow.
Several types of braking systems are avail-
able. Surge Brakes -
The surge brake actuator is
mounted on the trailer tongue with a
hydraulic line running to each trailer wheel.
Surge brakes are activated by the trailer
pushing against the hitch ball when the tow
vehicle is braking. Hydraulic surge brakes are
common on rental trailers and some boat
trailers. In this type of system, there is no
hydraulic or electric connection for brake
operation between the tow vehicle and the
trailer.
Electric Trailer Brakes - Electric braking
systems are activated by an electronic signal
sent from a trailer brake controller (special
brake sensing module).
Have a professional supplier of towing
equipment make sure the trailer brakes are
properly installed and demonstrate proper
brake function testing.WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
. Be certain your vehicle maintains a level
position when a loaded or unloaded
trailer is hitched. Do not drive the vehicle
if it has an abnormal nose-up or nose-
