2020 INFINITI Q50 2-18

5-6Starting and driving
Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it is
the driver’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 com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
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 ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.Additional information
.Since the spare tire (if so equipped) is not
equipped with the TPMS, the TPMS
does not monitor the tire pressure of
the spare tire.
. The TPMS will activate only when the
vehicle is driven at speeds above 16
MPH (25 km/h). Also, this system may
not detect a sudden drop in tire pressure
(for example a flat tire while driving).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is
inflated to the recommended pressure,
the vehicle must be driven at speeds
above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
. The “Tire Pressure Low - Add Air”
warning appears in the vehicle informa-
tion display when the low tire pressure
warning light is illuminated and low tire
pressure is detected. The “Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light turns
off.
The “Tire Pressure Low - Add Air”
warning does not appear if the low tire
pressure warning light illuminates to
indicate a TPMS malfunction. .
The “Flat Tire - Visit dealer” warning (if
so equipped) appears in the vehicle
information display when the low tire
pressure warning light is illuminated and
one or more flat tires are detected.
. Tire pressure rises and falls depending on
the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure after driving
because the tire pressure rises after
driving. Low outside temperature can
lower the temperature of the air inside
the tire which can cause a lower tire
inflation pressure. This may cause the
low tire pressure warning light to illumi-
nate. If the warning light illuminates in
low ambient temperature, check the tire
pressure for all four tires.
. You can also check the pressure of all
tires (except the spare tire) in the vehicle
information display. (See “Vehicle infor-
mation display” (P.2-18).)
. After the ignition switch is placed in the
ON position, it may take a period of time
for the tire pressure to be displayed while
the vehicle is driven. Depending on the
radio wave circumstance, tire pressure
may not correctly be displayed.
For additional information, see “Low tire
pressure warning light” (P.2-12) and “Tire
Pressure Monitoring System (TPMS)” (P.6-
3).

Some indicators and warnings for operation
are displayed in the vehicle information
display between the speedometer and tach-
ometer. (See “Vehicle information display”
(P.2-18).)
The ignition lock is designed so that the
ignition switch position cannot be switched
to LOCK until the shift lever is moved to the
P (Park) position.
When the ignition switch cannot be pushed
toward the LOCK position, proceed as
follows:
1. Move the shift lever into the P (Park)position.
2. Push the ignition switch to the OFF position. The ignition switch position
indicator will not illuminate.
3. Open the door. The ignition switch will change to the LOCK position.
The shift lever can be moved from the P
(Park) position if the ignition switch is in the
ON position and the brake pedal is de-
pressed.PUSH-BUTTON IGNITION
SWITCH POSITIONS
LOCK (Normal parking position)
The ignition switch can only be locked in this
position.
The ignition switch will be unlocked when it
is pushed to the ACC position while carrying
the Intelligent Key.
ACC (Accessories)
This position activates electrical accessories
such as the radio, when the engine is not
running.
ON (Normal operating position)
This position turns on the ignition system
and electrical accessories.
OFF
The engine can be turned off in this position.
The ignition lock is designed so that the
ignition switch cannot be switched to the
LOCK position until the shift lever is moved
to the P (Park) position.
CAUTION
Do not leave the vehicle with the push-
button ignition switch in ACC or ON
positions when the engine is not running
for an extended period. This can dis-
charge the battery.
EMERGENCY ENGINE SHUT OFF
To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
. Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds.
