VW ID.4 2023 Owner's Manual ➜ Brake energy recuperation

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.  
Brake energy recuperation  
Brake energy recuperation  
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, an  
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 engaged and ECO assist deactivated: No energy recuperation.  
Selector lever position 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 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 gear where possible.  
130  
Never let the vehicle roll down mountains or hills in the  
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.  
Messages about driving  
General driver information  
Anticipatory driving  
An inconsistent driving style increases consumption. When the driver actively pays attention to traffic, this can prevent frequent acceleration and braking  
maneuvers. Maintaining enough distance to the vehicle driving ahead helps you to drive with better anticipation.  
Avoiding full acceleration  
Excessively high speeds increase the rolling resistance and air resistance and with that, the power needed to move the vehicle. Never drive at the maximum vehicl  
speed.  
Checking tire pressures  
Low tire pressures cause wear as well as increased rolling resistance of tires, and this increases consumption. Use tires with optimal rolling resistance.  
Adapt the tire pressures to the load:  
Follow the specifications on the tire pressure label Checking the tire pressure.  
Tire Pressure Monitoring System How the Tire Pressure Monitoring System Works .  
WARNING  
If you drive at high speed and without sufficient safety distance, accidents and serious or fatal injuries can result.  
Always adapt your speed and remain a safe distance to vehicles driving ahead according to the visual, weather, road, and traffic conditions.  
Eco tips  
The correct driving style can help to  
reduce consumption, pollution, and  
wear on the electric drivetrain, brakes,  
and tires. The following tips will help  
you conserve the environment and your  
money.  
Using brake energy recuperation  
If Eco assist is deactivated in the Infotainment system and gear  
is engaged and the accelerator pedal is not pressed, the vehicle will “coast”.  
If Eco assist is activated in the Infotainment system and gear  
is engaged and the accelerator pedal is not pressed, the vehicle recuperates energy automatically.  
also adjusts to the current driving situation and external conditions such as the vehicle in front and speed limits. The energy from the rolling vehicle is also used to  
charge the high-voltage battery. The vehicle's brakes are also applied.  
In gear , if the accelerator pedal is not pressed, strong recuperation will occur.  
Furthermore, the energy recuperation increases when the brake pedal is pressed.  
Have maintenance performed regularly
