service indicator INFINITI QX50 2021 Owner's Manual

FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down
hills.
The gauge needle returns to 0 (Empty) after
the ignition switch is placed in the OFF
position.
The low fuel warning comes on when the
amount of fuel in the tank is getting low. Refill the fuel tank once the Low Fuel warn-
ing indicator in the vehicle information dis-
play illuminates as indicated by
Low
Fuel.
The
indicates that the fuel-filler door is
located on the driver's side of the vehicle.
CAUTION
• If the vehicle runs out of fuel, the
Malfunction Indicator Light (MIL) may
come on. Refuel as soon as possible. Af-
ter a few driving trips. the
light
should turn off. If the light remains on
after a few driving trips, have the vehicle
inspected. It is recommended that you
visit an INFINITI retailer for this service.
• For additional information, see “Mal-
function Indicator Light (MIL)”
(P. 2-15).
DISTANCE TO EMPTY (DTE)
Displays the estimated distance the vehicle
can be driven before refueling. The value is
calculated based on recent fuel economy, the
amount of fuel remaining in the fuel tank, and
the actual fuel consumption. Changes in driving patterns or conditions can
cause the DTE value to vary. As a result, the
value displayed may differ from the actual
distance that can be driven.
DTE display will change to “---” when the fuel
level in the tank is getting low, prior to the fuel
gauge reaching 0 (Empty).
NOTE:
• The DTE value after refill is estimated
based on recent fuel economy and amount
of fuel added.
• If a small amount of fuel is added, or the ignition is on during refueling, the display
may not be updated.
• Conditions that affect the fuel economy will also affect the estimated DTE value
(city/highway driving, idle time, remote
start time, terrain, seasonal weather,
added vehicle weight, added deflectors,
roof racks, etc.).

regular tire pressure check. Be sure to
check the tire pressure regularly.
• If the vehicle is being driven at speeds of
less than 16 mph (25 km/h), the TPMS
may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
