warning light NISSAN ALTIMA 2020 Owner´s Manual

When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.
The supplemental air bag warning
light
is used to indicate malfunctions
in the pretensioner system. For additional
information, refer to "Supplemental air bag
warning light" in this section. If the opera-
tion of the supplemental air bag warning
light indicates there is a malfunction, have
the system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s
Manual.

FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle returns to 0 (Empty) af-
ter the ignition switch is placed in the OFF
position.
The low fuel warning message shows in
the vehicle information display when the
amount of fuel in the tank is getting low. Refill the fuel tank before the gauge reg-
isters 0 (Empty).
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, theMalfunction 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
af ter a few driving trips, have the ve-
hicle inspected. It is recommended
that you visit a NISSAN dealer for this
service.
∙ For additional information, refer to “Malfunction Indicator Light (MIL)” in
this section.
DISTANCE TO EMPTY (DTE)
Displays the estimated distance the ve-
hicle 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 consump-
tion. Changes in driving patterns or conditions
can cause the DTE value to vary. As a result,
the value displayed may differ from the ac-
tual 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 af ter 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 esti-
mated DTE value (city/highway driv-
ing, idle time, remote start time, ter-
rain, seasonal weather, added vehicle
weight, added deflectors, roof racks,
etc.).
