STARTING AND DRIVING

Automatic braking when stationary
Automatic braking when stationary (Auto hold)
means that the driver can release the brake
pedal while maintaining braking effect when the
car has stopped at traffic lights or a junction.
Function
When the car has stopped, the brakes are acti-
vated automatically. The function can use either
foot brake or parking brake to hold the car sta-
tionary and it works on all gradients. When the
accelerator pedal is depressed again, the brakes
are released.
When braking to a stop on a downhill or uphill
gradient - depress the brake pedal a bit harder
before releasing to ensure that the car does not
roll at all.
When stationary or when is the car is switched
off, the parking brake is applied after approx. 5
minutes.
Automatic deactivation
The function is deactivated automatically:
•
when the driver's door is open and the driv-
er's seatbelt is unfastened.
Switch for automatic brake
An indicator in the button illuminates when the function
is activated.
Activate or deactivate Auto hold with the switch
in the tunnel console. The function remains deac-
tivated until it is reactivated.
If the function is active and holds the
car with the foot brake (A-symbol illu-
minated) then the brake pedal must be
depressed at the same time as the
button is depressed in order to deactivate.
When the function is deactivated, hill start assist
(HSA) remains active to prevent the car from roll-
ing backwards when starting on an uphill gradi-
ent.
