AT (Automatic
Transmission) CHECK
If the service warning appears while the
engine is running, or while driving, it may
indicate that the AT is not functioning prop-
erly and may need servicing. Have the sys-
tem checked, and if necessary, repaired
promptly. It is recommended that you visit
a NISSAN dealer for this service.
AT (Automatic Transmission) Error:
See Owner’s Manual
If this message appears while the engine is
running, or while driving, it may indicate
that the AT is not functioning properly and
may need servicing. Have the system
checked, and if necessary, repaired
promptly. It is recommended that you visit
a NISSAN dealer for this service.
Service AT
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
climbing steep grades in high tempera-
tures with heavy loads, such as when tow-
ing a trailer), engine power and, under
some conditions, vehicle speed will be
decreased automatically to reduce the
chance of transmission damage. Vehiclespeed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be reduced.
WARNING
When the high fluid temperature pro-
tection mode operation occurs, vehicle
speed may be gradually reduced. The
reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially
careful when driving. If necessary, pull
to the side of the road at a safe place
and allow the transmission to return to
normal operation; or have it repaired if
necessary.

Traffic Alert (RCTA)” (P. 5-41).
Cruise control indicator
This indicator shows the cruise control sys-
tem status.
For additional information, see “Cruise con-
trol” (P. 5-49).

ligent Cruise Control (ICC) system is en-
gaged. Under the following conditions, the
