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

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

WARNING
Electrostatic buildu pcan create sparks and
ignite fuel vapors. There is arisk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existin gelectrostatic buildu pis
thereby discharged.
! Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the
ignition if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could result in damage to the
fuel system and the engine. Notify a
qualified specialist workshop and have the
