clutch pedal all the way down before you start driving so the system 
recognizes that the parking brake should be released. 
Emergency braking function 
Only use the emergency braking function in an emergency, when you 
cannot stop the vehicle using the brake pedal ⇒ ! 
  Pull and hold the button ⇒ fig. 144 to brake the vehicle hard. An 
audio warning signal will sound at the same time. 
  To stop the braking maneuver, release the button or press the ac-
celerator pedal. 
  WARNING 
Improper use of the electronic parking brake can cause acci-
dents and severe injuries. 
  Never use the parking brake to slow down the vehicle when it 
is moving, except in an emergency. Braking distance is much 
longer, since only the rear wheels are braked. Always use the 
foot brake. 
  Never press the accelerator pedal when a selector lever posi-
tion or gear is engaged and the engine is running. The vehicle 
could begin moving, even if the electronic parking brake is set. 
  Never activate the throttle manually from the engine com-
partment when the engine is running and the automatic trans-
mission is in gear. The vehicle will start to move even if the 
parking brake is engaged.  
  NOTICE 
Even though the transmission is in Park (P), the vehicle may 
move a couple of inches (a few centimeters) forwards or back-
wards if you take your foot off the brake pedal after stopping the 
vehicle without first firmly setting the parking brake. 
  Vehicles with manual transmission: the electronic parking brake 
releases automatically when you release the clutch pedal and press 
the accelerator pedal at the same time.  
 
Brake booster 
The brake booster works only when the engine is running. It increas-
es the force on the brakes above and beyond the pressure put on the 
brake pedal by the driver. 
If the brake booster is not working, or if the vehicle has to be towed, 
you will have to push the brake pedal harder to make up for the lack 
of booster assistance and the resulting longer stopping distance ⇒ . 
  WARNING 
New brake pads do not provide maximum braking performance. 
  New brake pads do not have the best stopping power for the 
first 200 miles (320 km) and must be “broken in.” You can com-
pensate for the slightly reduced braking force by putting more 
pressure on the brake pedal. 
  Drive with extra care while the new brake pads are being bro-
ken in. This reduces the risk of collisions and serious personal 
injuries due to a loss of control over the vehicle. 
  Never follow other vehicles too closely or put yourself into 
other situations that might require sudden, hard braking, espe-
cially when the brake pads have not been broken in.  
  WARNING 
Overheated brakes will reduce the vehicle's stopping power 
and increase stopping distances considerably. 
  When driving downhill, the brakes have to work especially 
hard and heat up quickly. 
  Before driving downhill, especially on hills that are long or 
steep, always reduce speed and shift into lower gear (manual or 
automatic transmission). This will let the vehicle use engine 
braking and reduce the load on the brakes. Otherwise, the 
brake system could overheat and possibly fail. Only use the 
brakes when you need them to slow the vehicle down more or 
to stop. 
  A damaged front spoiler or a non-standard spoiler can re-
duce airflow to the brakes and make them overheat.
