R There is amalfunction in the fuel supply.
X Turn the SmartKey back to position 0in the ignition lock before
attempting to start the engine again.
X Try to start the engine again (Y page 137). Avoid excessively
long and frequent attemptstos tart the engine as these will drain
the battery.
If the engine does not start after several attempts:
X Consult aqualified specialist workshop. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak
or discharged.
X
Jump-start the vehicle (Y page 303).
If the engine does not start despite attemptstoj ump-start it:
X Consult aqualified specialist workshop, e.g. an authorized
Mercedes-Benz Center. The starter motor was exposed to

WARNING
If the clutch overheats, the electronic
management system is automatically
deactivated. This interrupts the power
transmission. The vehicle may, for example,
roll backwards on gradients. There is arisk of
an accident.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
The clutch may overheat if you hold the
vehicle stationary on uphill gradients by
depressing the accelerator pedal. If the clutch
overheats, awarning tone sounds. The StopVehicle Shift to
PLeave Engine Running displaym
essage appears in the
multifunction display. You will only be able to
continue your journey once the clutch has
cooled down and the displaym essage in the

Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
Instead, only ever hold the vehicle stationary
on uphill gradients by:
R depressing the brake pedal
R activating the HOLD function
R engaging the electric parking brake Kickdown Use kickdown for maximum acceleration:
X
Depress the accelerator pedal beyond the
