HOW TO USE ONE-PEDAL DRIVING AND REGEN ON DEMAND

Difficulty Level: Intermediate  |  Time Required: 2 Minutes  |  Tools Required: None  |  Related Parts, Products, Services or Technology: None

If your electric vehicle is equipped with One-Pedal Driving† and Regen on Demand†, they can help you slow down and stop your vehicle under certain conditions. You can use them separately or use them together.

One-Pedal Driving makes your vehicle slow down quickly when you lift your foot off the accelerator. Regen On Demand is a separate feature that lets you use a paddle on the back of your steering wheel to control how fast you slow down. 

Important: State of Charge and Regenerative Braking 

To help you maintain your vehicle’s battery, it is recommended you only charge your battery to 80% capacity for daily use. This allows space in the battery for regenerative braking, which uses the electric motor to help slow the vehicle while simultaneously charging the vehicle with free energy. For longer trips, you can adjust your charge above 80% for extended range. See your Owner’s Manual for more information.

How to Turn One-Pedal Driving On

1. Before you can use One-Pedal Driving, you have to turn it on. To turn the feature on: 

a. Select the Vehicle Controls app on your centre display.

b. Then, select “Drive and Park” to turn One-Pedal Driving on or off and customize the level of braking it offers.

c. You may also see a One-Pedal Driving button on your screen that you can use to quicky turn One-Pedal Driving on or off. 

2. One-Pedal Driving will remain on until you turn it off, even if you turn your vehicle off and then back on again. 

HOW TO USE ONE-PEDAL DRIVING

When One-Pedal Driving is engaged, the position of your accelerator pedal determines how the vehicle will behave — either accelerating, coasting, slowing down quickly, slowing down gradually or coming to a complete stop. 

  1. Press down on the accelerator pedal to accelerate, as usual. 
  2. When you take your foot completely off the accelerator pedal while you’re driving, the vehicle will slow down quickly. 
  3. If you lift your foot off the pedal only slightly, the vehicle will slow down more gradually.  
  4. You can control how aggressively the vehicle slows down by adjusting how much you lift off the accelerator pedal. To continue driving, press the accelerator pedal. 
  5. While using One-Pedal Driving, you can also continue to use your brakes as needed to slow or stop the vehicle. 

HOW TO USE REGEN ON DEMAND

You can manually slow your vehicle down with the Regen On Demand paddle. It converts the energy from your vehicle's movement and returns it to the vehicle's battery. You can use this feature on its own or together with One-Pedal Driving. 

To use Regen On Demand: 

1. Pull the paddle on the back of your steering wheel toward you and hold it.  

a. The vehicle will slow down more quickly when you hold the paddle. 
b. If your vehicle is equipped with Variable Regen On Demand, you can adjust the amount of deceleration you experience with the Regen On Demand paddle. To do this, pull the paddle closer to you for more aggressive deceleration. 

2. Release the paddle when you want to continue normal driving. 

3. If the vehicle is brought to a complete stop while you’re holding the paddle, the vehicle will not creep forward when you release the paddle. Use the accelerator pedal to move forward. 

4. While using Regen on Demand, you can also continue to use your brakes or accelerator pedals as needed to slow or stop the vehicle. 

CONDITIONS IMPACTING ONE-PEDAL DRIVING AND REGEN ON DEMAND

There are several conditions that may impact these features: 

  • Battery conditions: When the battery is fully charged or the battery temperature is extremely cold or hot, these features may not operate as normal. When this happens, the vehicle will automatically blend in normal brakes as needed to maintain a consistent driving feel. 
  • Road and vehicle conditions: These features are not recommended for use in slippery road conditions (wet, snowy or icy roads). 

In any of the above cases, be prepared to use your brake pedal as needed to slow and stop the vehicle. 

USAGE TIPS

  • Avoid unnecessary decelerations and accelerations and remember to slow down gradually when possible while using these features. 
  • Always use your brake pedal for hard, emergency braking situations when you need to bring the vehicle to a stop quickly. 
  • In some cases, like when you’re on a steep hill or if the vehicle is held at a stop for a while, the vehicle’s parking brake may turn on. Simply press the accelerator pedal again to move forward (the parking brake will automatically disengage). 
  • It is recommended you do not use these features in slippery road conditions (wet, snowy or icy roads).
