Driving and parking
The engine does not start. You cannot
hear the starter.
The battery may not be sufficiently
charged.
Have the vehicle jump-started
(page 707).
If the engine will not start despite a jump
start:
Call Roadside Assistance.
Contact an authorized Mercedes-Benz
Center or call Roadside Assistance.
Driving off
Depress the brake pedal.
The gear selector lever can now be
used.
Shift the automatic transmission to
drive positionD or reverse gearR.
Release the brake pedal.

matically released (
page 412).
The red brake warning lamp 0
(USA only) or ! (Canada only) in the
instrument cluster goes out.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.
i
Wait for the gear selection process to com-
plete before setting the vehicle in motion.
i
Shifting from park position P to reverse
gearR, neutral positionN, or drive positionD is
only possible with the brake pedal depressed.
Without the brake pedal depressed, the gear se-
lector lever can be moved, but the parking pawl
remains engaged, not allowing shifting to occur.
!
If you hear a warning signal, the red indica-
tor lamp 0 (USA only) or ! (Canada only)
in the instrument cluster flashes and the mes-
sage “Please Release Parking Brake” appears in
the multifunction display when driving off, you
are driving with the electronic parking brake en-
gaged, or you are carrying out an emergency
brake application with the electronic parking
brake.
