Mazda CX-9 Owners Manual: Cruise Control Function

While this function is operating, the headway control operation is canceled and only the cruise control function operates.

The vehicle speed can be set more than about 25 km/h (16 mph).

Use the cruise control function on expressways and other highways which do not require a lot of repeated acceleration and deceleration.

WARNING

Do not use the cruise control function in the following locations: Otherwise, it could lead to an accident.

• Roads with sharp curves and where vehicle traffic is heavy and there is insufficient space between vehicles.

  (Driving under these conditions using the cruise control function is not possible)

• Steep down slopes (Set speed may be exceeded because sufficient engine braking cannot be applied)
• Slippery roads such as ice or snow-bound roads (Tires could spin causing you to lose vehicle control)

Always drive carefully: The warnings and brake control will not operate after the headway control function is canceled and the system is switched to only the cruise control function. Depress the brake pedal to decelerate according to the surrounding conditions while keeping a safer distance from the vehicle ahead and always driving carefully.

Switching to cruise control function

When the MODE switch is pressed until the system switches to the cruise main indication (white) while the MRCC with Stop & Go function system is turned on, the system switches to the cruise control function.

When the system switches to the cruise control function, the indicator and multi-information display notify the driver as follows:

• The MRCC with Stop & Go function set indication (green) or the MRCC with Stop & Go function main indication (white) is turned off, and the cruise main indication (white) is turned on.
• A message is displayed in the multi-information display.

WARNING

Always turn off the cruise control function when it is not in use: Leaving the cruise control function turned on when it is not in use is dangerous as it could operate unexpectedly, resulting in an accident.

How to set the speed

Adjust the system to the desired vehicle speed using the accelerator pedal.

When the SET+ or SET- switch is pressed, the cruise set indication (green) is turned on and headway control begins.

NOTE

• The system may not be able to maintain the set speed constantly depending on driving conditions such as steep up or down slopes.
• The speed will continue increasing while the SET+ switch is pressed and held.

  The speed will continue decreasing while the SET- switch is pressed and held.

How to increase the set speed

The set speed can be increased using the following operations:

To increase speed using the SET+ switch

Press and hold the SET+ switch and release the switch at the desired speed.

The set speed can be adjusted incrementally (1 km/h (1 mph) increments) by pressing the switch and releasing it immediately. For example, if the switch is pressed 4 times, the set speed increases by about 4 km/h (4 mph).

To increase speed using accelerator pedal

Depress the accelerator pedal and press the SET+ or SET- switch at the desired speed.

If the switch is not operated, the system returns to the set speed after you release your foot from the accelerator pedal.

How to Decrease the Set Speed

Press the SET- switch continuously and release the switch at the desired speed.

The set speed can be adjusted incrementally (1 km/h (1 mph) increments) by pressing the switch and releasing it immediately. For example, if the switch is pressed 4 times, the set vehicle speed decreases by about 4 km/h (4 mph).

Canceling the function

When the cruise control function is canceled and the RES switch is pressed while the vehicle speed is 25 km/h (16 mph) or faster, the speed returns to the original set speed.

Canceling using OFF/CANCEL switch

When the OFF/CANCEL switch is pressed once, the cruise control function is cancelled.

Automatically cancel

The cruise control function is canceled automatically in the following cases.

• The brake pedal is depressed.
• The parking brake is applied.
• The selector lever is shifted to P or N position.

NOTE

• If the vehicle speed decreases by about 15 km/h (9.4 mph) or more than the set speed, the cruise control function may be canceled.
• When the vehicle speed is less than 21 km/h (13 mph), the cruise control function is canceled. In this case, the vehicle speed will not return to the original set speed even if the vehicle is accelerated to 25 km/h (16 mph) or higher and the RES switch is pressed.

  Reset the cruise control function.
