DRIVER CORRECTION DEVICES AND AIDS (4/12)
Emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system is for detecting an emer-
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig-
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.
Hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decele-
ration. Braking anticipation
Depending on the vehicle, when you
rapidly release the accelerator, the
system anticipates the braking ma-
noeuvre in order to reduce stopping
distances.
Special cases
When using the cruise control:
– if you use the accelerator, when you
release it, the system may be trigge-
red;
– if you do not use the accelerator, the system will not be triggered.
Operating faults
When the system detects an operat-
ing fault the message “Check brak-
ing system” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.

Operating faults
When the system detects an operating
fault, the
warning light lights up
on the instrument panel, with the mes-
sage “Active braking disconnected”.
There are two possibilities:
– The system is temporarily experien- cing difficulties (for example: sensor
obscured by dirt, mud, snow, etc.)
in this case, park the vehicle and
switch off the engine. Clean the de-
tection zone of the radar. When you
next start the engine, the warning
light and the message go out;
– If this is not the case, this may arise from another cause; contact an
Approved Dealer.3

AUTOMATIC GEARBOX (6/6)
Special circumstances
– If the bends and road surface
do not allow you to stay in auto-
matic mode (e.g. in the mountains),
we recommend that you change
to either temporary or permanent
manual mode.
This will prevent the automatic gear-
box from changing gear repeatedly
when climbing, and permit engine
braking on long descents.
– In cold weather, wait a few seconds
before disengaging position P or N
and engage the lever in D or R to
prevent the engine stalling.
Operating faults
– When driving , if the “Check auto
gearbox” message appears on the
instrument panel, it indicates a fault.
Contact your approved Dealer as
soon as possible.
– When driving , if the message
“Gearbox overheating” appears on
the instrument panel, stop the ve-
hicle to allow the gearbox to cool
down.
Contact your approved Dealer as
soon as possible.
– If a vehicle with an automatic
gearbox breaks down, please refer
to the information on “Towing” in
Section 5.
An impact to the under-
side of the vehicle while
manoeuvring (e.g.: strik-
ing a post, raised kerb or
other street furniture) may result in
damage to the vehicle (e.g.: defor-
mation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap-
proved Dealer.
In very cold weather, the system
may prevent the gears from being
shifted in manual mode until the
gearbox reaches the right tempera-
ture.

Vibrations. Tyres not inflated to correct pres-
sures, incorrectly balanced or dam-
aged. Check the tyre pressures: if this is not the
problem, have them checked by an ap-
proved Dealer.

sarily a fault. Smoke may be caused
by particle filter regeneration. Please refer to the information on “Special
features of diesel versions” in Section 2.
Smoke under the bonnet. Short-circuit or cooling system leak. Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
