Hill start assist
Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll.
G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may roll away. There is a risk
of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
R
you are pulling away on a level road or a
downhill gradient
R
on vehicles with automatic transmission, the
transmission is in position N
R

ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
When pulling away again, the engine starts auto-
matically. The ECO start/stop function thereby
helps you to reduce the fuel consumption and
emissions of your vehicle.
