This can occur, for example, if the driver moves the shift
lever to request a transmission gear that is not allowed
under the current operating conditions.
With the vehicle at a standstill, engine running and the
shift lever in DRIVE (D), REVERSE (R), or MANUAL
(M), the buzzer sounds and the transmission automati-
cally shifts to NEUTRAL (N) when:
• The accelerator and/or brake pedals are not operated
for at least three minutes.
• The brake pedal is pressed for longer than 10 minutes.
• The driver’s door is opened and the accelerator and
brake are not operated for at least 1.5 seconds.
• The driver selected gear does not match the engaged
transmission gear.
• A fault has been detected in the transmission.
A Blinking Warning:
• The driver selected gear does not match the engaged
transmission gear, the gear information in the cluster
and on the bezel will blink.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch to activate TOW/
HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due
to excessive shifting. When operating in TOW/HAUL
mode, the transmission shift calibration is modified to
accommodate steep grades in the smoothest possible
manner. TOW/HAUL mode is only applicable in the
DRIVE (D) position.
