Starting
off with
a trailer
To prevent rolling back unintentionally
on an incline, do
the following:
-
Keep the switch pulled and depress the accelerator. The
parking brake stays applied and prevents the vehicle
from rolling backward.
- You can release the switch once you are sure that you are
developing enough forward momentum
at the wheels as
you depress the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch
pulled out and accelerating - just as you would when starting on a
hill with a conventional hand brake. •
Emergency
braking
In the event that the conventional brake system fails or
locks.
-
Pull the switch and continue to pull it to slow your vehicle
with the parking brake in an emergency.
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated . The vehicle is
braked at all four wheels by activating the hydraulic brake system.
Brake performance is similar to making an emergency stop~
& .
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled . As soon as
the switch is released , or the accelerator pedal is depressed, emer-
gency braking stops.
&
WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle as if you had made a full brake application. The laws
of physics cannot be suspended even with ESP and its associated
components (ABS, ASR, EDS). In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away - risking an
accident. •
Driver
messages
in the instrument
cluster
Caution: Vehicle parked too steep
This message appears when the parking brake is applied on an
incline that exceeds about 30%.
In this case the braking power of the parking brake may not be
adequate to prevent the vehicle from rolling unintentionally.
Please release parking brake
This m essage appears, when a gear is selected and the accel erator
pedal is depressed - release the parking brake.
Press brake pedal to release parking brake
This driver message appears when the switch to release the parking
brake was pressed. The parking brake can only be released if you
press the brake or accelerator pedal and press the switch at the
same time .

'Jlf
symbol
