DRIVING CORRECTION DEVICES AND AIDS (3/8)
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 decel-
eration.
Operating faults
When the system detects an operat-
ing fault the message “CHECK ABS”
appears on the instrument panel along
with the
© warning light.
Consult an approved dealer.
Driver assistance with a
trailer
This system helps to maintain control
over the vehicle while using a trailer.
It detects shaking caused by towing a
trailer under certain driving conditions.
Operating conditions
– The towbar must be approved by an authorised dealer;
– the harness must be approved by an authorised dealer;
– the towbar must be connected to the vehicle.
Operating principle
The function stabilises the vehicle by:
– asymmetric braking of the front wheels to reduce shaking caused by
the trailer;
– braking of all four wheels and limita- tion on engine torque to reduce the
vehicle speed until the shaking has
stopped.
Warning light
 flashes on the in-
strument panel to inform the driver.
Active emergency braking
Using the sensor 1, the system calcu-
lates the distance separating the vehi-
cle from the one in front and alerts the
driver if there is a risk of a front-end col-
lision. The driver can then brake the ve-
hicle to limit the damage arising from a
collision.
Note: Make sure that the sensor 1 is
not obscured (by dirt, mud, snow, etc.).

The self-locking differential controls the
torque transmitted to each rear wheel.
Depending on the grip conditions on
the road surface, and at low speeds
(under 20 mph/30 kph), this device en-
ables wheel torque to move automati-
cally, thereby providing increased grip.
This enables the grip potential of each
wheel to be used to the fullest possi-
ble extent, thereby enabling the vehicle
to run over areas with decreased grip
(e.g.: work sites, muddy ground, etc.).
Once the rear wheels return to surfaces
with normal grip (eg: return to paved
roads), the self-locking differential
device will be deactivated, sometimes
accompanied by a noise (with no con-
sequence to vehicle behaviour). You
have the option of turning this device
off yourself, once normal grip condi-
tions have resumed, by briefly releas-
ing the accelerator
SELF-LOCKING DIFFERENTIAL
This function is an addi-
tional driving aid.
However, it does not in-
crease the vehicle’s limits
and should not encourage you to
drive more quickly.
It cannot, therefore, under any cir-
cumstances replace the vigilance or
the responsibility of the driver.

TRANSPORTING OBJECTS (2/2)
Towing
Fitting the towing ball
Position the ball within the range of
height D, which must be between 350
and 420 mm, with the vehicle laden.
Tighten bolts 3, observing a tightening
torque of 196 Nm (Newton metres).

C
Front-wheel drive, standard wheels
C = 1,110 mm.
Rear-wheel drive, standard wheels
C = 1,760 mm.
Rear-wheel drive, dual wheels
C = 1,753 mm.
D
If the towbar ball obscures the regis-
tration plate or the rear fog lights, it
should be removed when not in use.
In all cases, comply with local legis-
lation.
Permissible nose weight, maxi-
mum permissible towing weight,
braked and unbraked: refer to
the information on “Weights” in
Section 6.
Choice and fitting of towing
equipment
Maximum weight of towing equip-
ment: 26 kg
For fitting and conditions of use,
refer to the equipment’s fitting ins-
tructions.
Please keep these instructions with
the rest of the vehicle documenta-
tion.
