G Warning!
The electro-hydraulic brake system requires
electrical power to operate.
If the electro-hydraulic brake system is
activated as the brake pedal is first
depressed, you may feel a reduced pedal
resistance and longer pedal travel than
normal. When releasing the pedal, you may
also feel the brake pedal pulsate and you may
hear a sound which is caused by the
activation of the electro-hydraulic brake
system pump. This is normal and not an
indication of a malfunction. Pedal travel
returns to normal when you release the brake
pedal and the sound soon ceases.
If you experience the above while driving and
the red brake warning lamp illuminates
and/or warning messages appear in the
multifunction display, the brake system is
malfunctioning. Follow the instructions of the
warning message(s) and have the brake
system checked immediately.
A malfunction in the vehicle’s power supply or
electrical system may impair brake system
operation and switch it into its emergency
operation mode. In such a case, the red brake
warning lamp comes on and warning
messages appear in the multifunction display
while driving. To brake, the driver must then
apply significantly greater brake pedal
pressure and depress the pedal much further
to obtain the expected braking effect. If
necessary, apply full pressure to the brake
pedal. Brakes are only applied to the front
wheels. Stopping distance is increased!
If there is a malfunction in the electro-
hydraulic brake system, we recommend that
the vehicle be transported with all wheels off
the ground using flatbed or appropriate wheel
lift/dolly equipment.
G Warning!
