Parking Brake, Checking

Pay attention to the instructions on the test stand screen.

Activating >>T U V mode<< :

• The seat belt is buckled.
• Rear axle in the one-axle roller test stand
• The engine is off and the ignition is on.
• Auto Hold is off.
• The front wheels must be stationary.
• The rear wheel must rotate for at least 5 seconds non-stop between 2.5 and 9 km/h (1.6 and 5.6 mph)

>>T U V mode<< is indicated when the yellow Electric Parking Brake Malfunction Indicator Lamp -K214- is displayed.

-- The yellow electro-mechanical parking brake symbol with a line through it appears in the instrument cluster. Refer to the appropriate Service Information; Instruments and Indicator Lamps.

TIP:

The electromechanical parking brake does not lock all the way in the >>T U V mode<< immediately.

Pressing the Electromechanical Parking Brake Button -E538- three to four times in a row gradually increases the tension force.

Operating the Electromechanical Parking Brake Button -E538- a fifth time loosens the electromechanical parking brake.

-- Start the motor and on vehicles with vacuum brake booster wait approximately 5 seconds until there is sufficient pressure built.

Ending >>T U V mode<< :

• Front wheels, speed greater than 0 km/h (0 mph)
• Rear wheels, speed less than 2.5 km/h (1.6 mph) or greater than 9 km/h (5.6 mph)
• Ignition off.
