WARNING
vehicle
The limits set by the physics of driving cannot be
overcome, even with the drive-off assistant. Despite
the drive-off assistant, responsibility for stopping and
starting on hills lies with the driver.
When stopping and starting on slippery surfaces (e.g.
icy or loose substrate), the drive-off assistant cannot
be guaranteed to provide assistance. The vehicle can
slip in such cases.
If the drive-off assistant is not working, the driver
cannot be assisted when hill starting.
e
Always adjust your driving style to the road sur-
face and the vehicle load; use the footbrake if
necessary.
e
Hold the vehicle with the footbrake.

The vehicle is automatically secured for a short time
against rolling back against the desired direction of
travel.

2. The direction of travel uphill corresponds to gear
lever position D or R or in gear lever position M
the first gear.
3. Release footbrake
�� The vehicle is briefly held on the gradient
to enable driving off and prevent the vehicle
from rolling back.
4. Drive off in the usual way.
Information

If the vehicle is held on the incline with the elec-
tric parking brake, it can be started in the usual
way.
The electric parking brake detects the drive-off
request and is released automatically.
− If the driver's seat belt is unfastened and the
driver's door is opened, the electric parking brake
is automatically activated.

Brakes

General safety instructions
Obstructed pedals
WARNING
Unsuitable or incorrectly secured floor mats can inad-
vertently actuate or block the accelerator pedal and
brake pedal.
This can lead to unintentional or more difficult accel-
eration and braking.
e
Only use floor mats that are suitable for the vehi-
cle.
e
Secure floor mats properly and do not lay them
loosely.
e
Do not lay several floor mats on top of each
other.
e
Ensure that floor mats are securely fitted again
after they have been removed, e.g. for cleaning.
Absence of brake power
WARNING
assistance
The brake booster is only operative when the drive
is running. Consequently, much greater force needs
to be applied to the pedal during braking when the
drive is switched off or in the event of a faulty brake
booster.
e
Vehicles with a defective brake may only be
towed on a car transporter or trailer.
g Refer to chapter "Towing and tow-starting" on
page 198.
