System Outline

1. Setting 

   <In vehicle-to-vehicle distance control mode>

   When the - SET SW is pressed and the ON-OFF SW is ON (The cruise operation indicator is lit) at a vehicle speed above the lower settable vehicle speed limit, the vehicle speed at which the - SET SW released is stored as the set vehicle speed and the vehicle is controlled to maintain that speed. However, when the - SET SW is pressed at a speed that exceeds the higher settable vehicle speed limit, the higher settable vehicle speed limit is stored as the set vehicle speed instead and the vehicle is controlled to maintain that speed.

   <In constant speed control mode>

   When the - SET SW is pressed while the ON-OFF SW is ON (The cruise operation indicator is lit), and the vehicle is traveling at a speed which is between the lower settable vehicle speed limit and the high speed limit, then the vehicle speed at which the - SET SW is released will be stored as the set vehicle speed and the vehicle is controlled to maintain that speed.

2. Method for Changing Set Vehicle Speed 

   <In vehicle-to-vehicle distance control mode>

   1. Lowering the set vehicle speed

      When the - SET SW is momentarily pressed (For approximately 0.6 seconds) while driving with the cruise control active, the set vehicle speed will decrease in increments of 5 mph for U.S.A. models and 5 km/h for other models each the SW is pressed.

      When the - SET SW is held ON, the set vehicle speed decreases continuously in increments of 5 mph for U.S.A. models and 5 km/h for other models until the SW is released.

      However, if the set vehicle speed reaches the lower settable vehicle speed limit, the set vehicle speed cannot be decreased any further.

      When the set vehicle speed is changed, the vehicle will decelerate (or accelerate if needed) to that speed.

      NOTE: The actual vehicle speed will not be set if the - SET SW is released after the vehicle has been accelerated using the accelerator pedal. In such cases, the set vehicle speed decreases by 5 mph for U.S.A. models and 5 km/h for other models, as described above.
   2. Increasing the set vehicle speed

   * When the + RES SW is momentarily pressed (For approximately 0.6 seconds), the set vehicle speed will increase in increments of 5 mph for U.S.A. models and 5 km/h for other models for each SW operation.

   When the SW is held ON, the set vehicle speed increases continuously in increments of 5 mph for U.S.A. models and 5 km/h for other models until the SW is released.

   However, if the set vehicle speed reaches the higher settable vehicle speed limit, the set vehicle speed cannot be increased any further.

   When the set vehicle speed is changed, the vehicle will accelerate (or decelerate if needed) to that speed.

   * When the + RES SW is pressed during follow-up control, the vehicle speed will not increase and the follow-up control continues. However, the set vehicle speed will be changed.

   <In constant speed control mode>

   1. Deceleration

      * When the - SET SW is pressed and held while driving with the cruise control active, the vehicle will decelerate gradually as long as the SW is held down. When the SW is released, the actual vehicle speed is stored as the set vehicle speed and the vehicle is controlled to maintain that speed. If the - SET SW is released when the actual vehicle speed exceeds the high speed limit such as when the vehicle is running down a slope; the vehicle is controlled using the high speed limit as the set vehicle speed.

      * When the - SET SW is momentarily pressed (For approximately 0.6 seconds), the set vehicle speed decreases in increments of 1.6 km/h (1 mph) each time it is pressed. However, if the SW is pressed when the set vehicle speed differs from the actual vehicle speed by 5 km/h (3 mph) or more, the actual vehicle speed at which the SW is released is stored in the memory and the vehicle is controlled to maintain that speed.

   2. Acceleration

   * When the + RES SW is pressed and held while driving with the cruise control active, the vehicle will accelerate gradually as long as the SW is held down. When the SW is released, the vehicle speed will be stored as the set vehicle speed and the vehicle is controlled to maintain that speed.

   * If the actual vehicle speed exceeds the high speed limit during while the + RES SW is being held down, the vehicle is controlled using the high speed limit until the SW is released. After the SW is released, the high speed limit is stored as the set vehicle speed and the vehicle is controlled to maintain that speed.

   * When the + RES SW is pressed momentarily (For approximately 0.6 seconds), the set vehicle speed increases in increments of 1.6 km/h (1 mph) each time it is pressed. However, if the SW is pressed when the set vehicle speed differs from the actual vehicle speed by 5 km/h (3 mph) or more, the set speed will not be changed.

   * If the - SET SW is pressed after the vehicle has been accelerated using the accelerator pedal, the set vehicle speed is reset to the vehicle speed at which the - SET SW was released. However, pressing the SW has no effect when the actual vehicle speed is higher than the high speed limit.

3. Lower Settable Vehicle Speed Limit 

   * This refers to the lower limit of the settable speed range and is approximately 45 km/h (27 mph). It is different from the low limit speed.

   * No set vehicle speed is stored in the memory when the vehicle runs below the lower settable vehicle speed limit.

4. Low Speed Limit 

   This is the minimum speed to which the cruise control can be set and is approximately 40 km/h (25 mph). If the vehicle speed drops below the low speed limit while driving with the cruise control active, the cruise control will be cancelled automatically.

   However, in vehicle-to-vehicle distance control mode and constant speed control mode the set vehicle speed will be retained in the memory.

5. Higher Settable Vehicle Speed Limit (Only in Vehicle-to-Vehicle Distance Control Mode) 

   This refers to the maximum settable speed in vehicle-to-vehicle distance control mode and is approximately 135 km (85 mph).

6. High Speed Limit (Only in Constant Speed Control Mode) 

   This refers to the maximum settable speed in constant speed control mode and is approximately 200 km/h (125 mph).

7. Resume 

   * If the cruise control was canceled but the ON-OFF SW is still ON (The cruise operation indicator is lit), then the + RES SW is pressed and the actual vehicle speed is higher than the low speed limit, the vehicle speed control automatically resumes to maintain the vehicle speed that was stored before the cruise control was canceled.

   * When the follow-up control has been activated, and the driver or the vehicle ahead changes lanes and the road ahead becomes clear, the vehicle accelerates automatically and gradually to the set vehicle speed. If the + RES SW is pressed at this time, the vehicle speed will be rapidly increased (Only in vehicle-to-vehicle distance control mode).

8. Shift-Down Control 

   If the vehicle climbs a hill while driving with the cruise control active, the gear may be shifted down by the A/T control. When the hill climb has been determined to have finished, based on the throttle opening information, the gear will be shifted up after the timer expires.

9. Cancel 

The cruise control will be canceled if any of the following signals are input while driving with the cruise control active (The set vehicle speed will not be erased).

1. Stop lamp SW ON (Brake pedal depressed)
2. D position circuit in Park/Neutral position SW from ON to OFF*

   * Shift lever moved from D to N

   * Gear changes to 3, 2, or 1 in sequential shift mode (Shift lever in S)

3. CANCEL SW of control SW ON
4. ON-OFF SW OFF (Set vehicle speed erased)
5. VSC activation
