2020 INFINITI QX50 fuel

∙ Use only an original equipment type fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emission
control system. An incorrect cap can re-
sult in a serious malfunction and possible
injury. It could also cause the
Mal-
function Indicator Light (MIL) to come
on.
∙ Never pour fuel into the throttle body to attempt to start your vehicle.
∙ Do not fill a portable fuel container in the vehicle or trailer. Static electricity can
cause an explosion of flammable liquid,
vapor or gas in any vehicle or trailer. To
reduce the risk of serious injury or death
when filling portable fuel containers:
– Always place the container on the ground when filling.
– Do not use electronic devices when filling.
– Keep the pump nozzle in contact with the container while you are filling it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
∙ Do not use a fuel containing more than15% ethanol in your vehicle. For addi-
tional information, refer to “Fuel recom-
mendation” in the “Technical and con-
sumer information” section of this
manual.
∙ The Loose Fuel Cap warning message will be displayed if the fuel-filler cap is not
properly tightened. It may take a few
driving trips for the message to be dis-
played. Failure to tighten the fuel-filler
cap properly after the Loose Fuel Cap
warning is displayed may cause the Mal-
function Indicator Light (MIL) to
illuminate.
∙ Failure to tighten the fuel-filler cap prop- erly may cause the
Malfunction In-
dicator Light (MIL) to illuminate. If
the
light illuminates because the
fuel-filler cap is loose or missing, tighten
or install the cap and continue to drive
the vehicle. The
light should turn
off after a few driving trips. If the
light does not turn off after a few driving
trips, have the vehicle inspected. It is rec-
ommended that you visit an INFINITI re-
tailer for this service. ∙ For additional information, refer to
“Malfunction Indicator Light (MIL)” in
the “Instruments and controls” section of
this manual.
∙ If fuel is spilled on the vehicle body, flush it away with water to avoid paint
damage.
NOTE:
Changing ignition switch status during the
refueling process may cause a delay in fuel
gauge response.

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
∙ Keep your engine tuned up. Malfunctions in the ignition, fuel injection, or electrical
systems can cause over rich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that you visit an INFINITI retailer for this
service.
∙ Avoid driving with an extremely low fuel level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
∙ Do not race the engine while warming it up.
∙ Do not push or tow your vehicle to start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to en-
sure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated payment device on
the key ring. Restart the engine using the
following procedures:1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passengers to do likewise.
∙ Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2. Press the Park button to place the ve-
hicle in P (Park) or move the shift lever to
N (Neutral). P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the ignition
switch in any position.
∙ If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator pedal
a little (approximately 1/3 to the floor)
and while holding, crank the engine.
Release the accelerator pedal when
the engine starts.

∙ Remember not to drive at high speeds forextended periods of time in lower than
8th gear. This reduces fuel economy.
When shifting up
Use the + (up) side paddle shifter. (Shifts to
higher range.)
When shifting down
Use the (down) side paddle shifter. (Shifts
to lower range.)
∙ The transmission will automatically downshift the gears. (For example, if you
select the 3rd range, the transmission will
shift down between the 3rd and 1st
gears.)
∙ Moving the shift lever rapidly to the same side twice will shift the ranges in succes-
sion.
When canceling the manual shift mode
Move the shift lever to the D (Drive) position
to return the transmission to the normal driv-
ing mode. ∙ In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving performance
and reduces the chance of vehicle dam-
age or loss of control. ∙
When this situation occurs, the Continu-
ously Variable Transmission (CVT) posi-
tion indicator will blink and the chime
will sound.
∙ In the manual shift mode, the transmis-
sion may shift up automatically to a
higher range than selected if the engine
speed is too high. When the vehicle
speed decreases, the transmission auto-
matically shifts down and shifts to 1st
gear before the vehicle comes to a stop.
∙ CVT operation is limited to automatic drive mode when CVT fluid temperature
is extremely low even if manual shift
mode is selected. This is not a malfunc-
tion. When CVT fluid warms up, manual
mode can be selected.
∙ When the CVT fluid temperature is high, the shift range may upshift in lower rpm
than usual. This is not a malfunction.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the ac-
celerator pedal to the floor. This shifts the
transmission down into a lower gear, de-
pending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, when climb-
ing steep grades in high temperatures with
heavy loads, such as when towing a trailer),
engine power and, under some conditions,
vehicle speed will be decreased automatically
to reduce the chance of transmission dam-
age. Vehicle speed can be controlled with the
accelerator pedal, but the engine and vehicle
speed may be limited.
Fail-safe
When the fail-safe operation occurs, the
Continuously Variable Transmission will not
be shifted into the selected driving position.
If the vehicle is driven under extreme condi-
tions, such as excessive wheel spinning and
subsequent hard braking, the fail-safe sys-
tem may be activated. The Malfunction Indi-
cator Light (MIL) may come on to indicate
the fail-safe mode is activated. For addi-
tional information, refer to “Malfunction In-
dicator Light (MIL)” in the “Instruments and
controls” section of this manual. This will oc-
cur even if all electrical circuits are function-
ing properly. In this case, place the ignition
