2020 INFINITI QX50 brake light

Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. For addi-
tional information, refer to “Wheels and tires”
in the “Technical and consumer information”
section of this manual.
WARNING
∙ The use of tires other than those recom-mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
adversely affect the ride, braking, han-
dling, VDC system, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, headlight
aim and bumper height. Some of these
effects may lead to accidents and could
result in serious personal injury.
∙ For 2WD models, if your vehicle was originally equipped with four tires that
were the same size and you are only re-
placing two of the four 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 conditions
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 dimension. Wheels of a
different off-set could cause premature
tire wear, degrade vehicle handling char-
acteristics, affect the VDC system
and/or interference with the brake discs.
Such interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information on
wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical and
consumer information” section of this
manual.
∙ When replacing a wheel without the TPMS, such as the spare tire, 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 that you visit
an INFINITI retailer for this service.
∙ Replacing tires with those not originally 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 recom-
mended that you visit an INFINITI re-
tailer for ID registration.
∙ Do not use a valve stem cap that is not specified by INFINITI. The valve stem cap
may become stuck.
∙ Be sure that the valve stem caps are cor- rectly fitted. Otherwise the valve may be
clogged up with dirt and cause a malfunc-
tion or loss of pressure.
∙ Do not install a damaged or deformed wheel or tire even if it has been repaired.
Such wheels or tires could have structural
damage and could fail without warning.
∙ The use of retread tires is not recommended.
∙ For additional information regarding tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
8-36Do-it-yourself

When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
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 miss-
ing, and check for any loose wheel nuts.
Tighten if necessary.
Tire rotation*: Tires should be rotated every
7,500 miles (12,000 km). If your vehicle is
equipped with different sized tires in the front
and rear, tires cannot be rotated.
Tires*: Check the pressure with a gauge of-
ten and always prior to long distance trips. If
necessary, adjust the pressure in all tires, in-
cluding the spare, to the pressure specified.
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 un-
even or abnormal tire wear, there may be a
need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, re-
fer 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 repaired by an INFINITI
retailer, or a INFINITI Certified Collision Cen-
ter. To locate a collision 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 scheduled 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.
Brake pedal: Check the pedal for smooth op-
eration. 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 that 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.
Continuously Variable Transmission (CVT) P
(Park) position mechanism: On a fairly steep
hill check that the vehicle is held securely with
the shift lever in the P (Park) position without
applying any brakes.
Parking brake: Check the parking brake op-
eration regularly. The vehicle should be se-
curely held on a fairly steep hill with only the
parking brake applied. If the parking brake
does not securely hold the vehicle, it is recom-
mended that you visit an INFINITI retailer for
service.
Maintenance and schedules9-3

Seat belts:Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters 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 en-
sure they operate smoothly and all latches
lock securely in every position. Check that the
head restraints/headrests move up and
down smoothly and the locks (if so equipped)
hold securely in all latched positions.

This vehicle is equipped with a sealed main-
tenance free battery. It is recommended that
you visit an INFINITI retailer for this service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of elec-
tronic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold. Engine drive belt*:
Make sure the drive belt is
not frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil
to drain back into the oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have the
exhaust system inspected. It is recommended
that you visit an INFINITI retailer for this
service. For additional information, refer to
“Exhaust gas (carbon monoxide)” in the
“Starting and driving” section of this manual.
Fluid leaks: Check under the vehicle for fuel,
oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping
from the air conditioner after use is normal. If
you should notice any leaks or if fuel fumes
are evident, check for the cause and have it
corrected immediately.

10-2Technical and consumer information

Safety chains
Always use suitable safety chains between
your vehicle and the trailer. The safety chains
should be crossed and should be attached to
the hitch, not to the vehicle bumper or axle.
The safety chains can be attached to the
bumper if the hitch ball is mounted to the
bumper. Be sure to leave enough slack in the
chains to permit turning corners.
Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available 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 us-
ing the vehicle tail light, stop light 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 module/converter that ex-
ceeds these power requirements may dam-
age the vehicle’s electrical system. See a
reputable trailer retailer to obtain the
proper equipment and to have it installed.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. Vehicles
equipped with the optional trailer tow pack-
age are equipped with a 7-pin trailer harness
connector. If your trailer is equipped with a
flat 4-pin connector, an adapter will be
needed to connect the trailer lights to the
vehicle. Adapters are available at auto parts
stores and hitch retailers.
Trailer brakes
Most states require a separate braking sys-
tem 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 hydrau-
lic 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 be-
tween the tow vehicle and the trailer. Electric Trailer Brakes -
Electric braking sys-
tems 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 di-
rectly to the vehicle brake system.
Pre-towing tips
∙ Be certain your vehicle maintains a level position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle
if it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
∙ Always secure items in the trailer to pre- vent load shift while driving.
∙ Keep the cargo load as low as possible in the trailer to keep the trailer center of
gravity low.
Technical and consumer information10-25

∙ Load the trailer so approximately 60% ofthe trailer load is in the front half and
40% is in the back half. Also make sure
the load is balanced side to side.
∙ Check your hitch, trailer tire pressure, ve- hicle tire pressure, trailer light operation,
and trailer wheel lug nuts every time you
attach a trailer to the vehicle.
∙ Be certain your rearview mirrors conform to all federal, state or local regulations. If
not, install any mirrors required for tow-
ing before driving the vehicle.
∙ Determine the overall height of the ve- hicle and trailer so the required clearance
is known.
Trailer towing tips
In order to gain skill and an understanding of
the vehicle’s behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability
and braking performance will be somewhat
different than under normal driving condi-
tions.
∙ Always secure items in the trailer to pre- vent load shift while driving. ∙ Lock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadver-
tently becoming unlatched.
∙ Avoid abrupt starts, acceleration or stops.
∙ Avoid sharp turns or lane changes.
∙ Always drive your vehicle at a moderate speed.
∙ When backing up, hold the bottom of the steering wheel with one hand. Move your
hand in the direction in which you want
the trailer to go. Make small corrections
and back up slowly. If possible, have
someone guide you when you are back-
ing up.
Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:
CAUTION
If you move the shift selector to the P
(Park) position before blocking the wheels
and applying the parking brake, transmis-
sion damage could occur. 1. Apply and hold the brake pedal.
2. Have someone place blocks on the
downhill side of the vehicle and trailer
wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the
blocks absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park).
6. Turn off the engine.
To drive away: 1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
10-26Technical and consumer information

Malfunction Indicator Light (MIL) comes on
steady for 20 seconds and then blinks for
10 seconds , the I/M test condition is “not
ready”. If the MIL does not blink after 20 sec-
onds, the I/M test condition is “ready”. It is
recommended that you visit an INFINITI re-
tailer to set the “ready condition” or to pre-
pare the vehicle for testing.The ProPILOT Assist is equipped with an
Event Data Recording function.
The main purpose is to record, in certain crash
or near crash-like situations, such as an air
bag deployment or hitting a road obstacle,
data that will assist in understanding how a
vehicle’s systems performed. The Data re-
cording function is designed to record data
related to driver operation, vehicle dynamics
and system status for a short period of time.
The Data recording function in this vehicle is
designed to record such data as:
∙ Driver operational status of accelerator, brake, handle etc.
∙ Detection status of a vehicle ahead and lane markers
∙ Vehicle information such as vehicle speed
∙ Information on the operation of the Pro- PILOT Assist
∙ ProPILOT Assist malfunction diagnosis information
∙ Images from multi-sensing front camera (Available only when SRS air bag or FEB
with Pedestrian Detection system is acti-
vated) The ProPILOT Assist does not record con-
versations, sounds or images of the inside of
the vehicle.
