Driving and operating 117functionality. To release the electricalparking brake when p is on, pushdown the m switch and hold it downuntil the control indicator m goes off.If the light remains on, seek theassistance of a workshop.NoteDriving with the parking brake oncan overheat the brake system andcause premature wear or damage tobrake system parts. Make sure thatthe parking brake is fully releasedand the control indicator m is offbefore driving.Automatic release of the electricalparking brakeThe electrical parking brake isautomatically released when thevehicle is running, placed into gearand an attempt is made to drive away.Avoid rapid acceleration when theelectrical parking brake is applied, toreduce wear of parking brake lining.Electrical parking brake m controlindicator 3 69.Electrical parking brake fault pcontrol indicator 3 69.Driver Information Centre (DIC) 3 73.Regenerative brakingRegenerative braking takes some ofthe energy of the moving vehicle andturns it back into electrical energy.This energy is then stored back intothe high voltage battery system,contributing to increased energyefficiency.The hydraulic disc brakes work withthe regenerative braking to ensureeffective braking, in the event a highbraking demand is requested, forexample.The braking system is computer-controlled and combines theregenerative braking with theconventional hydraulic disc brakes tomeet any deceleration requirement.The controller interprets the brakingrequest and applies regenerativebraking, conventional hydraulicbraking or a combination of both, asnecessary. Because the controllerapplies the hydraulic brakes throughits high pressure accumulator, youmay occasionally hear the motor‐driven pump when the system isrecharged.In the event of a controller problem,the brake pedal may be harder topush and the stopping distance maybe longer.Driver Information Centre (DIC) 3 73.
