start running again after some time
if the coolant temperature rises
due to a build-up of heat, or if the engine is hot and the engine
compartment is heated up further by direct sunlight.
Electro-mechanical parking brakeOperation
The electro-mechanical parking brake replaces the hand-
brake.– Pull switch ⇒fig. 132 to apply the parking brake. The
indicator lamp in the switch will light up.
– Depress the brake or accelerator pedal and press the switch at the same time to release the parking brake. The
indicator lamp in the switch will go out.Your vehicle is equipped with an electro-mechanical parking brake.
The parking brake replaces the co nventional handbrake, and is
mainly intended to prevent the vehicle from rolling away acciden-
tally.
However, the electro-mechanical pa rking brake also offers a number
of convenience and safety features in addition to the functions of a
normal handbrake. When driving away
•
The parking brake auto release function releases the parking
brake automatically when you wish to start moving ⇒page 122,
“Driving away from a standstill”.
•
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The
braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Emergency braking function
An emergency braking function enables you to stop the vehicle even
if the conventional foot brake should fail to work ⇒page 123,
“Emergency braking function”.
Warning and indicator lamps
•
The warning lamps
 in the instrument cluster and in the switch
light up when the parking brake is applied with the ignition
switched on .
•
The warning lamps
 in the instrument cluster and switch light
up for approximately 20 seconds when the parking brake is applied
with the ignition switched off .
WARNING
Never press the accelerator pedal or release the clutch inadvert-
ently if a gear is engaged or if the selector lever is not in position
P or N (on automatic vehicles) while the vehicle is stationary with
the engine running. The vehicl e could otherwise start moving
immediately and possibly cause an accident.
Caution
If the symbol
 flashes in the centre display, or if the warning lamp
 flashes in the instrument cluster, there is a fault in the brake
system. You can press the button to obtain a message
explaining the faul t. If the message Parking brake ! appears, there is

braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Note
For safety reasons the parking brake will only release automatically
if the driver's seat belt
is engaged in its buckle.Driving away when towing a trailer
Please note the following po ints to prevent the vehicle
from rolling back unintentionally on a gradient.– Pull and hold the parking brake switch and press the
accelerator. The parking brake will remain engaged and
prevent any tendency to roll back down the slope.
– You can release the parking brake switch as soon as the engine is delivering enough power to the wheels.Depending on the weight of the vehicle and trailer and the steep-
ness of the slope, there may be a tendency to roll back downhill
when driving away from a standstill. You can prevent this by pulling
out the parking brake switch as you press the accelerator (in the
same way as with a conventional handbrake).Emergency braking function
This feature enables you to stop the vehicle if the main
brake system should fail or if the pedal is obstructed.– Pull out and hold the parkin g brake switch to stop the
vehicle with the parking brake in an emergency.
– The brakes will be released immediately if you release the switch or press down the accelerator.
If you pull out and hold the park ing brake switch at a road speed
above about 8 km/h, this will initiate an emergency brake applica-
tion. The brakes are then applied hy draulically at all four wheels.
The effect is the same as an emergency stop (full brake application)
⇒
To prevent the emergency braking function from being used acci-
dentally, a warning buzzer sounds when the switch is operated. The
brakes are released immediately when you release the switch or
press down the accelerator.
WARNING
You should only use the emergency braking function in a real
emergency, for example if the brake system should fail or if the
brake pedal is obstructed. If you use the emergency braking func-
tion by activating the parking brak e switch, the effect is similar to
a full brake application (emergenc y stop). Please remember that
the ESP (with its combined ABS, EDL and traction control func-
tions) is still subject to certain physical limits. In a corner or in bad
road or weather conditions an emergency stop can cause the
vehicle to skid or lose steering control.Driver messages in the instrument cluster displayCaution: Vehicle parked too steep
This message can appear when you apply the parking brake if the
car is parked on a gradient steeper than about 30%.
In this case the parking brake may not be strong enough to prevent
the vehicle from rolling back accidentally.
Please release parking brake
However, please remember that, for safety reasons, the parking
brake will only release automatically if the driver's seat belt is
buckled.
