Volkswagen ID.4: Brake energy recuperation

Limited driving power

The yellow indicator light turns on.

A message is displayed in the instrument cluster and an acoustic warning sounds.

The driving power is reduced considerably and could reduce further.

Climate control convenience functions are restricted.

1. Charge the high-voltage battery when the charge status is low.

In extremely cold or hot outside temperatures, the high-voltage battery is heated or cooled while driving. The driving power increases again after a short time.

Take note of the power display in the instrument cluster.

When the power increases again, the indicator light turns off.

All-wheel drive (4MOTION) is restricted

There is a malfunction in the all-wheel drive (4MOTION). The driving performance has been restricted.

• In the ID. cockpit, the text message All-wheel drive (4MOTION) is restricted. Please adapt your driving behavior appears.
• It is possible to continue driving with reduced driving performance.

Have the vehicle checked immediately by a suitably qualified professional. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

All-wheel drive (4MOTION) is currently restricted

The front engine's driving performance has been restricted in order to avoid overheating.

• In the ID. cockpit, the text message All-wheel drive (4MOTION) is currently restricted. Please adapt your driving behavior appears.
• It is possible to continue driving with reduced driving performance.

The driving performance limitation is removed in the following scenario:

• The front engine is no longer within a critical temperature range.

Electronic engine sound failed

The yellow indicator light comes on and an audible signal sounds.

A corresponding message is shown in the ID. cockpit.

1. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility to have the system inspected. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

It is possible to continue driving.

When slowing down the vehicle, and when the vehicle is rolling in overrun or driving downhill, electrical energy is created by the electric drivetrain and stored in the high-voltage battery. The electric drivetrain hereby works as a generator and creates an engine braking effect. This process is called "brake energy recuperation".

Engine braking varies depending on the selector lever position.

The vehicle brake light may light up when the brake energy recuperation is intense. The brake energy recuperation, and therefore also the engine braking effect, decreases as the charge level of the high-voltage battery increases. If the high-voltage battery is completely charged, there is no brake energy recuperation and no electric motor braking effect. If the vehicle detects that the road conditions do not permit safe contact between the wheels and the road, the energy recuperation, and therefore also the engine braking, is automatically reduced. The power display gives information about the available energy recuperation and the engine braking.

Depending on the selector lever position and the settings in the Infotainment system, the vehicle will recuperate differently:

Selector lever position D engaged and ECO assist deactivated: No energy recuperation.

Selector lever position D engaged and ECO assist activated: Automatic energy recuperation. The level of recuperation is automatically chosen depending on the navigation data and traffic situation.

Selector lever position B engaged: Intense energy recuperation.

The vehicle still recuperates energy if the brake pedal is pressed.

Eco assist

The ECO assist helps the driver use the vehicle's engine braking efficiently. It chooses the level of recuperation depending on the navigation data and the traffic situation.

The ECO assist can be switched on and off in the vehicle settings in the Infotainment system.

Driving on an incline

On inclines, it is best to drive in the B gear where possible.

Never let the vehicle roll down mountains or hills in the N neutral setting.

WARNING

Strong recuperation can cause traction loss and sliding, especially on slippery roads. This could cause loss of vehicle control, accidents and serious or fatal injuries.

• Only activate permanent high brake energy recuperation when the visibility, weather, road and traffic conditions allow and other road users are not put at risk by the vehicle deceleration and driving style.

WARNING

As the charge level of the high-voltage battery increases, the electric motor braking effect decreases and can completely disappear. The driving behavior may therefore change, which can cause accidents and serious or fatal injuries.

• Never completely charge the high-voltage battery at higher altitudes, for example on a mountain pass, in order to achieve braking efficiency thanks to brake energy recuperation on the subsequent drive down.
• Before driving on steep hills, reduce your speed.
• When driving on steep hills, reduce your speed with the vehicle brakes.
• Note that, in the absence of electric motor braking, the strain on the vehicle brakes increases.
