616 Practical hintsUnlocking/locking in an emergencyMechanically releasing the electric parking brake
The mechanical release device for the
electric parking brake is underneath the
fuel filler flap next to the fuel cap.
1Fuel filler flap
2Release tool
3Protective cap
Shift the automatic transmission to P
(page 367).
Place chock from vehicle tool kit
(page 611) under a rear wheel.
Open fuel filler flap1.
Remove protective cap3.
Screw release tool2 from vehicle tool
kit clockwise 2 to 3 rotations onto re-
lease lever.
Pull release tool2 in direction of ar-
row.
The electric parking brake is released.
The red indicator lamp 0 (USA only)
or ! (Canada only) in the instru-
ment cluster for the electric parking
brake flashes. The message “Parking
brake See Oper. Manual” appears on
the driver’s display.
After it has been unlocked, you can engage
the electric parking brake again from the
driver’s seat.
Press the electric parking brake handle
(page 364).
Warning!
G
If you mechanically release the electric
parking brake, the vehicle may start to move
on its own. Make sure that no one is in front
of or behind the vehicle. Otherwise, an acci-
dent could occur resulting in injury or fatali-
ty. Shift the automatic transmission to P and
secure your vehicle in place using the chock
from the vehicle tool kit.
i
You must pull the release tool with more
force if the electric parking brake cannot be re-
leased.
