Functions of the electric drive

Power output of the electric drive

The maximum torque of the electric drive is available immediately when you press the

accelerator.

Energy recovery (brake energy recuperation)

When the vehicle brakes, electrical energy is generated by the electric drive and then stored in

the high-voltage battery (→ Brake energy recuperation, Operation). This will also occur to a

certain extent when the vehicle is rolling to stop or travelling downhill.

The higher the charge level of the high-voltage battery, the lower the recuperation and thus also

the engine braking effect. No brake energy recuperation occurs and therefore no engine braking

effect is available once the high-voltage battery is fully charged →

Brake energy recuperation can be displayed in the instrument cluster or on the Infotainment

system screen.

Crawling function

The crawling function allows you to drive forwards or backwards slowly at a speed of around

5 km/h (3 mph) without pressing the accelerator.

The crawling function is automatically activated when:

—The vehicle’s drive system is activated and the D/B position or reverse gear R is selected.

—After every position change to D/B or R.

—The vehicle is moving at a speed of less than 10 km/h (6 mph) and the driver door is opened.

—The vehicle is at a standstill and the driver door is opened or the driver seat belt is unfastened

with the brake pedal pressed.

The crawling function is deactivated when the driver door is closed and seat belt is fastened if:

—The vehicle is driven faster than 10 km/h (6 mph).

—The selector lever is in position P or N.

—The vehicle has already been set in motion after the vehicle’s drive system was activated.

WARNING

Unintentional vehicle movements can cause serious injury.

●

If the vehicle’s drive system is activated and the selector lever is in D/B position or when the

reverse gear is engaged, the vehicle must be held with the foot brake. Even if just the

vehicle’s drive system is activated, the power transmission may not be fully interrupted so

that the vehicle “crawls”.

●

Never leave the vehicle in position N or D/B. The vehicle will roll downhill irrespective of

whether or not the electric drive is activated.

WARNING

The higher the charge level of the high-voltage battery, the lower the engine braking effect

from recuperation, to the point where no engine braking effect may be generated at all.

●

Reduce your speed before driving down a long, steep gradient.

When driving down a long, steep gradient, slow the vehicle using the vehicle brake.

Energy recovery (brake energy recuperation)

Fig. 1 Selector lever for driving mode: selecting recuperation. In right-hand drive vehicles the

display of the selector lever positions is mirrored.

Energy recovery (recuperation) can produce a braking effect. This braking effect may vary

depending on the gearbox program selected and the charge level of the high-voltage battery.

When the vehicle is braked, and when the vehicle is in overrun mode or driving downhill,

electrical energy is generated via the electric drive and stored in the high-voltage battery. The

electric drive then acts as a generator and creates an engine braking effect. This procedure is

known as brake energy recuperation.

The energy recovery level is displayed in the instrument cluster of the power display (→ Power

display, Description). When recuperation is active, the needle will move into the green area of

the display. The current brake energy recuperation level appears in the instrument cluster

display. You can display the statistics of the energy recovered in the last 30 minutes in the

infotainment system (→ e-displays, Description).

The extent of the engine braking effect varies depending on the recuperation level. If there is a

high level of brake energy recuperation, the brake lights on the vehicle can also light up. The

higher the charge level of the high-voltage battery, the lower the recuperation and thus the

engine braking effect effected. No brake energy recuperation occurs and therefore no engine

braking effect occurs when the high-voltage battery is completely charged. If the vehicle detects

that the road conditions will not allow the wheels to safely contact the road surface, the

recuperation and with it the engine braking effect will reduce automatically →

Selecting a brake energy recuperation level

There are a total of four brake energy recuperation levels. It is possible to shift up and down

through brake energy recuperation levels one to three by tapping the selector lever to the sides

→ Fig. 1 +

—Tap to the left, to shift up one energy recovery level.

—Tap to the right, to switch down a recuperation level.

—Press to the right for a few seconds to switch off recuperation.

To change up to brake energy recuperation level four: tap the selector lever to position . Tapping

again in the direction of the arrow will switch back to driving mode D and the last selected

recuperation level will be activated.

The vehicle is “coasting”. Energy is recuperated only during braking.

Minor energy recovery, energy recovery stage one.

Medium energy recovery, energy recovery stage two.

High energy recovery, energy recovery stage three.

Very strong energy recovery, energy recovery stage four.

In recuperation levels one - four, brake energy recuperation takes place during braking, coasting

to a stop and when driving downhill. The electric drive acts as a generator in this case. It converts

kinetic energy into electrical energy that is used to charge the high-voltage battery.

Driving down hills

The steeper the slope, the higher the recuperation level that should be selected → . Never

allow the vehicle to roll down mountains or hills in the neutral position N.

—Reduce your speed.

—Increase the energy recovery level with the selector lever (→ Driving mode selection for

electric vehicles, Function).

WARNING

Medium, high and very high brake energy recuperation can lead to loss of traction and skidding,

particularly on slippery roads. This can cause you to lose control of the vehicle, which can lead

to accidents and serious injuries.

●

Only use medium, high or very high recuperation if visibility, weather, road and traffic

conditions permit, and other road users are not put at risk due to the vehicle's acceleration

and your driving style.

WARNING

The higher the charge level of the high-voltage battery, the lower the engine braking effect, to

the point where no engine braking effect may be generated at all. This puts more strain on the

vehicle brake.

●

Never fully charge the high-voltage battery at high elevations, e.g. at the top of a pass, in

order to facilitate a braking effect by means of recuperation when descending.

●

Reduce your speed before driving down a long, steep gradient.

When driving down a long, steep gradient, slow the vehicle using the vehicle brake.
