CONTROL DESCRIPTION 

• Drive mode selector switches driving mode by drive mode select switch installed on center console finisher.
• Drive mode selector starts from STANDARD mode when the power switch ON.
• The vehicle characteristics are controlled from the STANDARD mode to any mode listed below:

  SPORT	Adjusts the engine and transmission 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 and transmission points are adjusted for improved fuel economy, providing such a driving features as smooth starting or constant cruising.

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

  x: Change from STANDARD

  Items	Drive mode		Control
  	SPORT	ECO
  Engine	x	x	Controls engine torque
  Transmission	x	x	Selects shift pattern
  Steering	x		Controls mode and response of steering
  Intelligent trace control	x		Controls intelligent trace control
  Brake control system	x		Controls braking force
  Driver assistance function			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
  ECO	Accelerator opening characteristics is changed.
  STANDARD	Normal
  SPORT	Accelerator opening characteristics is changed and use a high engine performance range.

  NOTE: After switching mode to a mode that engine output increase, engine output characteristics are changed after releasing the accelerator pedal.

TRANSMISSION CHARACTERISTICS 

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

  Drive mode select switch	Transmission status
  ECO	TCM controls shift characteristics of transaxle suitable for ECO mode.
  STANDARD	Normal
  SPORT	TCM controls shift characteristics of transaxle suitable for SPORT mode.

  For details, Refer to System Description .

STEERING CHARACTERISTICS 

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

  Drive mode select switch	Steering status
  ECO	Normal
  STANDARD	Normal
  SPORT	Quick

  NOTE: Steering characteristics change after mode switching when the steering angle is near the neutral position and the steering wheel is not turning.

INTELLIGENT TRACE CONTROL CHARACTERISTICS 

• The intelligent trace control characteristics when a mode is switched with the drive mode select switch is as follows.

  Drive mode select switch	Intelligent trace control status
  STANDARD	Normal
  ECO	Normal
  SPORT	OFF

BRAKE CONTROL SYSTEM CHARACTERISTICS 

• The brake control system characteristics when a mode is switched with the drive mode select switch is as follows.

  Drive mode select switch		Brake control system status
  ECO		Normal
  STANDARD		Normal
  SPORT		TCS: TCS allows more wheel spin before decreasing engine torque by engine torque control - later intervention. Brake limited slip differential (BLSD): Quicker activation of brake limited slip differential (BLSD) control in case of split-mu road surface.

DRIVER ASSISTANCE CHARACTERISTICS 

• The Driver assistance function characteristics when a mode is switched with the drive mode select switch is as follows.

  Drive mode select switch		Driver assistance status
  STANDARD		Normal
  ECO		Normal
  SPORT		Normal
