"Service engine soon" light

2bits

The "Service Engine Soon" light is otherwise known as the Multifunction Indicator Light (MIL). Intuitive, huh? The correct answer is (from the Owner's Manual):

. Malfunction indicator light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap. If
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 by a NISSAN dealer. You
do not need to have your vehicle towed to
the dealer.
. Malfunction indicator light blinking — An
engine misfire has been detected which may
damage the emission control system.
To reduce or avoid emission control system
damage:
a) Do not drive at speeds above 45 MPH
(72 km/h).
b) Avoid hard acceleration or deceleration.
c) Avoid steep uphill grades.
d) If possible, reduce the amount of cargo
being hauled or towed.
The malfunction indicator light may stop
blinking and remain on.
