CONTROL DESCRIPTION 

• The Infiniti Drive Mode Selector switches a vehicle mode with the flick of a switch (drive mode select switch) mounted on upper part of the center console and changes the control characteristics of the powertrain and chassis.
• When the ignition switch is turned ON from the OFF state, the Infiniti Drive Mode Selector starts in STANDARD mode regardless of drive mode during ignition switch ON.
• Active lane control operates in synchronization with the safety shield button by default.

  Active lane control can be set to operate in synchronization with the safety shield button on the settings screen of Lane Assist in Driver Assistance.

• The operation of the integral switch allows the driver to set vehicle characteristics as in the following table. The driver can drive the vehicle with the vehicle characteristics set by selecting PERSONAL with the drive mode select switch.

• The vehicle characteristics are controlled from the STANDARD mode to any mode listed below:

  Select mode	Vehicle characteristics control
  PERSONAL*	The vehicle characteristics can be set by the driver arbitrarily with the integral switch.
  SPORT+	The following characteristics enable a prompt, easily-predictable, and uplifting driving: Changing VDC control intervention timing to restrain unintended feel of intervention. Enhancing steering response and limiting rate of change in vehicle speed variable gear ratio. Changing the settings of suspension to those suitable to a sport driving. Changing active trace control function characteristics.
  SPORT	The control characteristics of engine and steering function can be changed. This mode uses the high engine performance region and adds a crisp feel in steering wheel operation. Changing the settings of suspension to those suitable to a sport driving. Changing active trace control function characteristics.
  ECO	ECO mode provides the features of assistance in the improvement of fuel economy such as smooth starts and stable cruising and facilities ECO driving.
  SNOW	Changing the engine characteristics to aid driving in slick condition.

  *: The setting is equivalent of STANDARD mode for Infiniti Drive Mode Selector, based on the driver's settings.
