Jeep Cherokee (KL): To Resume. To Vary The Speed Setting. Setting The Following Distance In ACC

Jeep Cherokee (KL) 2014 - 2023 Owners Manual > Understanding the features of your vehicle > Adaptive cruise control (acc) > To Resume. To Vary The Speed Setting. Setting The Following Distance In ACC

To Resume

If there is a set speed in memory push the RES (resume) button and then remove your foot from the accelerator pedal. The EVIC/DID will display the last set speed.

NOTE:

  • If your vehicle stays at standstill for longer than two seconds, then the driver will either have to push the RES (resume) button, or apply the accelerator pedal to reengage the ACC to the existing Set Speed.
  • ACC cannot be resumed if there is a stationary vehicle in-front of your vehicle in close proximity

WARNING!

The Resume function should only be used if traffic and road conditions permit. Resuming a set speed that is too high or too low for prevailing traffic and road conditions could cause the vehicle to accelerate or decelerate too sharply for safe operation. Failure to follow these warnings can result in a collision and death or serious personal injury.

To Vary The Speed Setting

To Increase Speed

While ACC is set, you can increase the set speed by pushing the SET + button.

The drivers preferred units can be selected through the instrument panel settings if equipped. Refer to " Understanding Your Instrument Panel" for more information.

The speed increment shown is dependant on the chosen speed unit of U.S. (mph) or Metric (km/h):

U.S. Speed (mph)

  • Pushing the SET + button once will result in a 1 mph increase in set speed. Each subsequent tap of the button results in an increase of 1 mph.
  • If the button is continually pushed, the set speed will continue to increase in 5 mph increments until the button is released. The increase in set speed is reflected in the EVIC/DID.

Metric Speed (km/h)

  • Pushing the SET + button once will result in a 1 km/h increase in set speed. Each subsequent tap of the button results in an increase of 1 km/h.
  • If the button is continually pushed, the set speed will continue to increase in 10 km/h increments until the button is released. The increase in set speed is reflected in the EVIC/DID.

To Decrease Speed

While ACC is set, the set speed can be decreased by pushing the SET - button.

The drivers preferred units can be selected through the instrument panel settings if equipped. Refer to " Understanding Your Instrument Panel" for more information.

The speed decrement shown is dependant on the chosen speed unit of U.S. (mph) or Metric (km/h):

U.S. Speed (mph)

  • Pushing the SET - button once will result in a 1 mph decrease in set speed. Each subsequent tap of the button results in a decrease of 1 mph.
  • If the button is continually pushed, the set speed will continue to decrease in 5 mph decrements until the button is released. The decrease in set speed is reflected in the EVIC/DID.

Metric Speed (km/h)

  • Pushing the SET - button once will result in a 1 km/h decrease in set speed. Each subsequent tap of the button results in a decrease of 1 km/h.
  • If the button is continually pushed, the set speed will continue to decrease in 10 km/h decrements until the button is released. The decrease in set speed is reflected in the EVIC/DID.

NOTE:

  • When you override and push the SET + button or SET - buttons, the new Set Speed will be the current speed of the vehicle.
  • When you use the SET - button to decelerate, if the engine's braking power does not slow the vehicle sufficiently to reach the set speed, the brake system will automatically slow the vehicle.
  • The ACC system decelerates the vehicle to a full stop when following a target vehicle. If an ACC host vehicle follows a target vehicle to a standstill, after two seconds the driver will either have to push the RES (resume) button, or apply the accelerator pedal to reengage the ACC to the existing Set Speed.
  • The ACC system maintains set speed when driving up hill and down hill. However, a slight speed change on moderate hills is normal. In addition, downshifting may occur while climbing uphill or descending downhill.

    This is normal operation and necessary to maintain set speed. When driving up hill and down hill, the ACC system will cancel if the braking temperature exceeds normal range (overheated).

Setting The Following Distance In ACC

The specified following distance for ACC can be set by varying the distance setting between four bars (longest), three bars (long), two bars (medium) and one bar (short).

Using this distance setting and the vehicle speed, ACC calculates and sets the distance to the vehicle ahead. This distance setting displays in the EVIC/DID.

Distance Setting 4 Bars (Longest)
Distance Setting 4 Bars (Longest)

Distance Setting 3 Bars (Long)
Distance Setting 3 Bars (Long)

Distance Setting 2 Bars (Medium)
Distance Setting 2 Bars (Medium)

Distance Setting 1 Bar (Short)
Distance Setting 1 Bar (Short)

To increase the distance setting, push the Distance Setting - Increase button and release. Each time the button is pushed, the distance setting increases by one bar (longer).

To decrease the distance setting, push the Distance Setting- Decrease button and release. Each time the button is pushed, the distance setting decreases by one bar (shorter).

If there is no vehicle ahead, the vehicle will maintain the set speed. If a slower moving vehicle is detected in the same lane, the EVIC/DID displays the "Sensed Vehicle Indicator" icon, and the system adjusts vehicle speed automatically to maintain the distance setting, regardless of the set speed.

The vehicle will then maintain the set distance until:

  • The vehicle ahead accelerates to a speed above the set speed.
  • The vehicle ahead moves out of your lane or view of the sensor.
  • The distance setting is changed.
  • The system disengages. (Refer to the information on ACC Activation).

The maximum braking applied by ACC is limited; however, the driver can always apply the brakes manually, if necessary.

NOTE: The brake lights will illuminate whenever the ACC system applies the brakes.

AProximityWarning will alert the driver if ACC predicts that its maximum braking level is not sufficient to maintain the set distance. If this occurs, a visual alert "BRAKE" will flash in the EVIC/DID and a chime will sound while ACC continues to apply its maximum braking capacity.

NOTE: The "Brake!" Screen in the EVIC/DID is a warning for the driver to take action and does not necessarily mean that the Forward Collision Warning system is applying the brakes autonomously.

Overtake Aid

When driving with ACC engaged and following a vehicle, the system will provide an additional acceleration up to the ACC set speed to assist in passing the vehicle.

This additional acceleration is triggered when the driver utilizes the left turn signal and will only be active when passing on the left hand side.
