2016 NISSAN FRONTIER check engine

WARNING
●Your brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it
to be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driv-
ing it could be dangerous.
● Pressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort and pedal travel.
● If the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked. It is
recommended you visit a NISSAN
dealer for this service.
Anti-lock Braking System (ABS) warning
indicator
When the parking brake is released and the
brake fluid level is sufficient, if both the brake
warning light and the ABS warning light illumi-
nate, it may indicate the ABS is not functioning
properly. Have the brake system checked and, if
necessary, repaired. It is recommended you visit
a NISSAN dealer for this service. Avoid high- speed driving and abrupt braking. For additional
information, refer to “Anti-lock Braking System
(ABS) warning light” in this section.
Charge warning light
If this light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and check
