Driver messages about the electrome-
chanical parking brake
The following driver messages may appear, de-
pending on the equipment installed in your vehi-
cle:
Special driving situations
Information on driving on hills and
gradients
Parking brake: fault. Safely stop vehicle. See
owner's manual
Please follow the tips below when driving on hills
and gradients or at high altitudes:
Parking brake: fault. Please release parking
brake
– Drive slowly and be ready for possible hazards.
– Do not try to turn round if you can’t make it up
a hill or gradient. Instead, drive back down in
reverse gear.
If one of these two messages appears, there is a
parking brake fault. If this message appears
while the vehicle is stationary, check whether the
parking brake can be released and reapplied. If
so, switch the vehicle off and on again.
– When driving down steep gradients, the down-
hill speed control function may be activated if
you press the brake pedal while in transmission
position D. The automatic gearbox will then se-
lect a suitable gear for the gradient and will at-
tempt to maintain the speed at which the vehi-
cle was travelling when the brakes were ap-
plied. You should still continue to use the
brakes as necessary. Downhill speed control is
deactivated as soon as the road levels out again
or you accelerate.
If the driver message still appears, if the parking
brake cannot be released or if the driver message
appears while the vehicle is moving, do not con-
tinue driving. Before leaving the vehicle, secure it
to prevent it from rolling away ðpage 99. Seek
professional assistance.
Parking brake: fault. Please contact work-
shop
Hold system: currently unavailable. See
owner's manual
– When driving down steep gradients, use the en-
gine braking effect by selecting driving pro-
gram S. This is especially important when tow-
ing a trailer or caravan. This will reduce the load
on the brakes.
There is a malfunction in the parking brake or
hold function. Drive to a qualified workshop with-
out delay to have the fault rectified. Do not park
the vehicle on a slope and secure the vehicle so it
cannot roll away ðpage 99.
– Use the hold function if appropriate.
WARNING
Parking brake: caution! Vehicle parked too
steep
– Drive only on gradients for which your vehi-
cle is designed. Do not exceed the vehicle’s
available climbing power. Your vehicle could
tip over or slide away.
Hold system: caution! Incline is too steep
If one of these two driver messages appears, the
braking force may not be sufficient to prevent the
vehicle from rolling away. Park the vehicle at a lo-
cation with a gradient that is less steep.
– Keep the vehicle straight when driving on
steep hills and gradients. If your vehicle is in
danger of tipping over, you must steer in the
direction of the gradient immediately – risk
of accident!
Parking brake is applied
The parking brake is applied. Press and hold the
brake pedal and release the parking brake.
– Always be ready to apply the brakes when
using the downhill speed control.
Please take over.
