stationar y, the vehicle is held for a brief
moment when you release the brake pedal:
-

p

ehicle load.
The gearbox operates without requiring any
intervention on your part.
For certain manoeuvres (for example
overtaking), you can obtain maximum
acceleration by pressing the accelerator pedal
hard down past the point of resistance, which
then produces an automatic change down to a
lower gear. When braking, the gearbox may change down
automatically in order to provide effective
engine braking.
If you lift your foot off the accelerator abruptly,
the gearbox will not engage a higher gear.

These two special programmes supplement
the automatic operation in very particular
conditions of use.
F
W
ith the gear lever in position D and the
engine running, press button A .
The gearbox automatically favours a dynamic
driving style.
SNOW programme " T"
F With the gear lever in position D and the
engine running, press button B .
The gearbox adapts to driving on slippery
roads.
This programme makes moving off easier and
improves traction in conditions of poor grip.
T appears in the instrument panel.
S appears in the instrument panel.
Return to automatic operation
F At any time, press the button selected again to exit from the programme engaged
and return to auto-adaptive mode. A strong snatch may be felt when
selecting
R for reverse gear.
In the event of a fault, the gearbox is
blocked in one gear; do not exceed a
speed of 62 mph (100 km/h).
Do not turn off the engine while the gear
selector is in position D or R .
Never press the accelerator and brake
pedals simultaneously. Braking and
acceleration should be done with the
right foot only. Pressing both pedals
simultaneously may damage the
gearbox.
Contact a CITROËN dealer or a
qualified workshop.
If the ambient temperature is
below
-23°C, the engine should be left
running at idle for four minutes, in order
to ensure the correct operation and
durability of the engine and gearbox.
