hill start assistance

This function assists the driver when

starting on hills. It prevents the vehicle

from rolling backwards, depending on

the slope, by automatically applying the

brakes when the driver lifts his/her foot

off the brake pedal to depress the ac-

celerator pedal.

System operation
It only operates when the gear lever is

in a position other than neutral (other

than

N or P for automatic transmis-

sions) and the vehicle is completely

stationary (brake pedal depressed)
The system holds the vehicle for ap-

proximately

2 seconds. The brakes are

then gradually released (the vehicle will

move according to the slope).

The hill start assistance

system cannot completely

prevent the vehicle from

rolling backwards in all sit-

uations (extremely steep gradients,

etc.).
In all cases, the driver may depress

the brake pedal to prevent the vehi-

cle from rolling backwards.
The hill start assistance function

should not be used for prolonged

stops: use the brake pedal.
This function is not designed to im-

mobilise the vehicle permanently.
If necessary, use the brake pedal to

stop the vehicle.
The driver must remain particularly

vigilant when driving on slippery or

low-grip surfaces and/or on hills.
Risk of serious injury.

eSC with understeer control

and traction control aSR

electronic stability control eSC
This system helps you to keep control

of the vehicle in critical driving condi-

tions (avoiding an obstacle, loss of grip

on a bend, etc.).

operating principle

A sensor in the steering wheel detects

the direction selected by the driver.
Other sensors throughout the vehicle

measure the actual direction.
The system compares driver input to

the actual trajectory of the vehicle and

corrects the trajectory, if necessary, by

controlling the braking of certain wheels

and/or engine power. In the event that

the system is engaged, warning light



flashes on the instrument panel.

Understeer control
This system optimises the action of the

ESC in the case of pronounced under-

steer (loss of front axle road holding).

traction control (aSR)
This system helps to limit wheelspin of

the drive wheels and to control the ve-

hicle when pulling away accelerating or

decelerating.
operating principle

Using the wheel sensors, the system

measures and compares the speed of

the drive wheels at all times and slows

down their over-rotation. If a wheel is

starting to slip, the system brakes au-

tomatically until the drive supplied be-

comes compatible with the level of grip

under the wheel again.
The system also adjusts the engine

speed to the grip available under the

wheels, independently of the pressure

exerted on the accelerator pedal.

operating faults

ing fault the message “Check ESC” and

Disabling the aSR function
In some situations (driving on very wet

ground: snow, mud, etc. or driving with

snow chains fitted), the system may

reduce the engine output to limit wheel-

spin. If this is not required, it is possible

to deactivate the function by pressing

switch 1.

The message “Traction control off” is

displayed on the instrument panel to

inform you.

Traction control (ASR) offers additional

safety; it is recommended that you do

not drive with the function disabled.

Correct this as soon as possible by

pressing switch 1 again.
Note: The function is reactivated auto-

matically when the ignition is switched

on or when a speed of approximately

24 mph (40 km/h) is exceeded.

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.

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.

When using the cruise control:

– if you use the accelerator, when you

release it, the system may be trig-

gered;

– if you do not use the accelerator, the

system will not be triggered.

Rear wheel steering

On equipped vehicles, this system,

when the vehicle is being driven, steers

the rear wheels according to driving

conditions: at low speed this system

offers manoeuvrability, at higher speeds

it optimises stability.
When driving at low speeds, the rear

wheels steer in the opposite direction to

the front wheels (figure A) to increase

the vehicle’s manoeuvrability. This is

used when driving in towns, on winding

roads, during parking manoeuvres, etc.

When driving at speeds above 40 mph

(60 km/h), the rear wheels steer in the

same direction as the front wheels

(figure B) to optimise the vehicle’s sta-

bility. This is useful when changing

lanes or when cornering etc.

Driving

When a limited speed has been stored

and this speed is not reached, driving is

similar to driving a vehicle without the

speed limiter function.
Once you have reached the stored

speed, no effort on the accelera-

tor pedal will allow you to exceed

the programmed speed except in an

emergency (refer to information on

“Exceeding the limit speed”).

varying the limit speed

To vary the limit speed, press switch 2

(+) repeatedly to increase the speed or

switch 3 (-) to decrease it.

exceeding the limit speed

It is possible to exceed the limit speed

at any moment. To do this: press the

accelerator pedal

firmly and fully

(beyond the kickdown point).
Whilst the speed is being exceeded,

the cruising speed displayed on the in-

strument panel flashes.
Then, release the accelerator pedal:

the speed limiter function will return as

soon as you reach a speed lower than

the stored speed.

Limited speed cannot be maintained
When driving down a steep gradient,

the system is unable to maintain the

limit speed: the stored speed will flash

on the instrument panel information dis-

play to inform you of this situation.

Cruise control

CRUISe CoNtRoL/SPeeD LIMIteR: cruise control function

(1/4)

The cruise control function helps you to

maintain your driving speed at a speed

that you choose, called the

cruising

speed.
This cruising speed may be set at any

speed above 20 mph (30 km/h).

The cruise control function

is in no way linked to the

braking system.

This function is an addi-

tional driving aid. However,

the function does not take

the place of the driver.

Therefore, it can under no circum-

stances replace the driver’s respon-

sibility to respect speed limits and to

be vigilant (the driver must always

be ready to brake). Cruise control

must not be used in heavy traffic, on

undulating or slippery roads (black

ice, aquaplaning, gravel) and during

bad weather (fog, rain, side winds

etc.).
There is a risk of accidents.

Controls

1 Main “On/Off” switch.

Parking distance control

This function is an additional aid that indicates the distance between the

vehicle and an obstacle whilst reversing, using sound signals.
Under no circumstances should it replace the driver’s care or responsibil-

ity whilst reversing.

The driver should always look out for sudden hazards during driving: always

ensure that there are no moving obstacles (such as a child, animal, pram or bi-

cycle, etc.) or small, narrow objects such as stones or posts in your path when

manoeuvring.

operating principle

Ultrasonic detectors, installed in the

front or rear bumper depending on the

vehicle, measure the distance between

the vehicle and an obstacle whilst re-

versing.
This measurement is indicated by

beeps which become more frequent the

closer you come to the obstacle, until

they become a continuous beep when

the vehicle is approximately 25 centi-

metres from the obstacle.

foot on the brake pedal: the gearbox is

in neutral and the drive wheels are me-

chanically locked by the driveshaft.
apply the handbrake or, depending

on the vehicle, ensure that the elec-

tronic parking brake is applied.

Special circumstances

–

If the road contours and bends

do not allow you to stay in auto-

matic mode (e.g.: in the mountains),

we recommend that you change to

manual mode.

This will prevent the automatic gear-

box from changing gears repeatedly

when climbing, and permit engine

braking on long descents.

–

In cold weather, to prevent the

engine from stalling, wait a few mo-

ments before shifting the selector

lever from position

P or N and en-

gaging

D or R.

–

vehicles not fitted with traction

control: on a slippery surface or

surface with a low level of adhe-

sion, change to manual mode and

select second gear before starting

the engine to avoid wheelspin when

starting.

Driving in manual mode

With the selector lever in position

D,

move the lever to the left. Shifting the

lever repeatedly allows you to change

gears manually:
– To move down through the gears,

push the lever backwards;

– To move up through the gears, push

the lever forwards.

The gear selected is displayed on the

instrument panel.

Special cases

Under certain driving conditions (e.g.

engine protection, electronic stability

program (ESP) operational etc.: ESC),

the “automatic system” may change

gear automatically.
Likewise, to prevent incorrect manoeu-

vres, a gear change may be refused by

the automatic system: in this case the

gear display flashes for a few seconds

as a warning.
