Deactivate easy entry/exit function

Vehicles with memory package (driver seat, steering column, mirrors) code 275

 Otherwise the driver seat and steering wheel move into a different position if the driver door is opened or closed for example. Damage to the upper frame can occur when the holding device is installed.

 It is switched off using the buttons on the steering wheel in the "Comfort" menu on the multifunction display, see vehicle owner's manual.

7

Move front wheels to straight-ahead position and secure steering wheel.

 To do this, swivel the sun visor to one side and insert the  retainer.

 The steering wheel must not be turned when the steering coupling has been removed. This will damage the fanfare horns and airbag clock spring contact beyond repair.

Insert suitable tool into the hole in the steering coupling (25) and pull the lower steering shaft (80a) upwards out of the steering coupling (25)

 Do not counter by holding the rubber boot or the temperature-resistant plastic disk on the lower steering shaft (80a). Do not use force (hammer blows, a lot of leverage), if necessary expand clamping groove slightly using a screwdriver.

 Installation: When inserting, pay attention to the pin for the steering coupling (25) and groove of the lower steering shaft (80a) (arrows).

 Ensure that rear of the engine does not touch the body.

16

Remove torque struts (18) from front axle carrier (1) and fold forwards

 The hexagon bolt (18a) must not turn. When loosening the nut always counterhold the hexagon bolt (18a), otherwise the lock tabs for caster adjustment in the rubber bushing will be sheared off.

 Installation: Do not tighten the nut of the hexagon bolt (18a) until the vehicle is in the ready-to-drive condition. The rubber mount in the torque strut (18) must not be installed distorted.

 Replace bolts

 Use only original bolts (4 x)

 Do not attach bolts at an angle
when screwing in

 Do not use an impact bolt tightener

 Observe tightening torque

 Installation: Before tightening the bolts (1f), align the front axle carrier (1) on the left and right using drift (a, 14.8 mm diameter).
