back. The braking force of the parking brake is
only released if sufficient drive power has been
built up at the wheels.

Tips
For safety reasons, the parking brake is only
released automatically when the driver's safe-
ty belt is buckled.
Emergency braking function
This is used if the conventional brake system
fails or locks up.
... To brake your vehicle in an emergency , pull the
~
switch and hold it pulled .
... As soon as you release the ~ switch or acceler-
ate, the braking 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. The brake performance is similar
to making an emergency stop¢ .&..
In order not to activate the emergency braking 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, emergency braking stops .
A
WARNING
Emergency braking should only be used in an
emergency, when the normal brake pedal has
failed or the brake pedal is obstructed. Using
the parking brake for emergency braking will
slow your vehicle down as if you had made a
full braking maneuver. ESC and the associat-
ed components (ABS, ASR, EDL) cannot over-
come the laws of physics. 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, which in-
creases the risk of an accident.

Introduction
The speed warning system helps you to stay un-
der a specified maximum speed .
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
You will hear a warning tone when your speed ex-
ceeds the stored value by approximately 3 mph
(3 km/h) . An indicator light.
(USA models)/ .
(Canada models) in the instrument cluster dis-
play also turns on at the same time. The indicator
light./.
turns off when the speed decreases
below the stored maximum speed.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.

Tips
Even though your vehicle is equipped with a
speed warning system, you should still watch
the speedometer to make sure you are not
driving faster than the speed limit.
' Setting the threshold
You can set, change and delete the warning
threshold in the Infotainment system.
