CONTROL DESCRIPTION 

• Drive mode selector switches driving mode by drive mode select switch installed on center console finisher.
• Drive mode selector starts from STANDARD/AUTO mode when the ignition switch ON.
• The vehicle characteristic can be set as following table in information display by the operation of the steering switch. The driver can drive the vehicle with the vehicle characteristics set by selecting PERSONAL with the drive mode select switch.
  NOTE: PERSONAL mode setting is linked with Log-in function.

  Category	Item	Setting
  PERSONAL mode	Acceleration	SPORT
  		STANDARD
  		ECO
  	Steering	SPORT
  		STANDARD
  	Trace Control	ON
  		OFF

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

  PERSONAL	This mode is used for adjusting drive modes. Turn the PERSONAL mode off for normal driving.
  SPORT	Adjusts the engine points for a higher response. The setting of the steering system is adjusted to moderately increase steering wheel effort for a sporty feel.
  ECO	Assists the driver's eco-driving. The engine points are adjusted for improved fuel economy, providing such a driving features as smooth starting or constant cruising.
  SNOW	This mode makes it easier to start and drive on snowy roads and frozen roads.

• For relationship between drive mode and each control item, refer to the following table.

  x: Change from STANDARD / AUTO

  Items	Drive Mode				Control
  	PERSONAL	SPORT	ECO	SNOW
  Engine	x	x	x	x	Change characteristic of throttle opening, and engine torque control
  Steering	x	x			Controls mode and response of steering
  Active trace control	x	x			Controls intelligent trace control
  Brake control system					Controls braking force
  AWD system				x	Controls drive torque distribution
  Driver assistance function				x	Controls ADAS function

ENGINE CHARACTERISTICS 

• The engine output characteristics when a mode is switched with the drive mode select switch is as follows.

  Drive mode select switch	Engine output
