Mercedes-Benz Citan 2015, Operating Instructions Manual

Page: 51 / 216

The ECO start/stop function automatically
switches the engine off when the vehicle is stop-
ped. When pulling away again, the engine starts
automatically. ASR then remains in the previ-
ously selected status. For example: if ASR was
deactivated before the engine was automati-
cally switched off, ASR will also remain off after
the engine is automatically started.
ESP
®
(Electronic Stability Program)
i Note the section on 'Important safety notes'
(
Y
page 47).
G
WARNING
If ESP
®
is malfunctioning it will not provide
any vehicle stabilisation. There is an
increased risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP
®
checked at a qualified specialist
workshop.
If ESP
®
is malfunctioning, the
÷
indicator
lamp lights up while the engine is running and
the engine power may be reduced
(
Y
page 137).
ESP
®
monitors driving stability and detects
understeering or oversteering (skidding) in good
time. If ESP
®
detects that the vehicle is deviat-
ing from the direction desired by the driver, one
or more wheels are braked to stabilise the vehi-
cle. The engine output is also modified to keep
the vehicle on the desired course within physical
limits. ESP
® greatly assists you when driving on
wet or slippery road surfaces. ESP
®
also stabil-
ises the vehicle when braking.
The
÷
warning lamp in the instrument cluster
flashes when ESP
®
is intervening.
If ESP
®
intervenes:
X ASR must not be switched off under any cir-
cumstances.
X
When pulling away, only depress the acceler-
ator pedal as far as required.
X Adapt your driving style to suit the prevailing
road and weather conditions.
i Use only wheels with the recommended tyre
sizes. Only then will ESP
®
function properly.
BAS (Brake Assist)
i Note the section on 'Important safety notes'
(
Y
page 47).
G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Brake Assist operates in emergency braking sit-
uations. If you depress the brake quickly, BAS
automatically increases the brake pressure,
thereby reducing the stopping distance.
When you release the brake pedal, the brakes
function as usual again. BAS is deactivated.
Protection against theft
Immobiliser
The immobiliser prevents your vehicle from
being started without the correct key.
X
To activate: remove the key from the ignition
lock.
X To deactivate: turn the key to position 2 in
the ignition lock.
Always take the key with you and lock the vehi-
cle when leaving the vehicle. If you leave the key
in the vehicle, anyone can start the engine.
i Starting the engine always deactivates the
immobiliser.
ATA (Anti-Theft Alarm system)
When ATA is primed, a visual and audible alarm
is triggered if the bonnet is opened or movement
is detected in the vehicle interior. This can occur
if someone reaches into the vehicle interior, for
example.
