Electronic stability control
ESC with understeer control
and traction control ASR
Electronic stability control ESC
(depending on vehicle)
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 the direction se-
lected by the driver and the actual di-
rection of the vehicle and corrects this
as necessary by applying the brakes
selectively and/or acting on the engine
power. Understeer control
This system optimises the action of the
ESC in the case of pronounced un-
dersteer (loss of front axle road hol-
ding).
Traction control ASR
This system helps to limit wheelspin of
the drive wheels and to control the vehi-
cle 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.
Warning light
 on the instrument
panel flashes when the function ESC
starts operating (with ASR).
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle beha-
viour to be adapted to suit the dri-
ving conditions.
However, the functions do not take
the place of the driver. They do
not increase the vehicle’s limits
and should not encourage you
to drive more quickly. Therefore,
they can under no circumstances
replace the vigilance or responsibi-
lity of the driver when manoeuvring
the vehicle (the driver must always
be ready for sudden incidents which
may occur when driving).
Operating fault
When the system detects an opera-
ting fault, the
 warning light on
the instrument panel comes on. In this
case, the ESC and the ASR are deac-
tivated.
Please contact an authorised dealer.

DRIVER CORRECTION DEVICES/AIDS (3/4)
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.
Operating faults
When the system detects an operating
fault, the warning light
x is dis-
played on the instrument panel.
Consult an approved dealer.

DRIVER CORRECTION DEVICES/AIDS (4/4)
Hill start assistance
This device assists the driver when
starting on hills (ascending or descend-
ing). It prevents the vehicle from rolling
forwards or backwards by automatically
applying the brakes when the driver lifts
their foot off the brake pedal to depress
the accelerator pedal.
System operation
It only operates when the gear lever is
in a position other than neutral (other
than N for sequential gearboxes) and
the vehicle is completely stationary
(brake pedal depressed).
The system holds the vehicle for ap-
proximately 2 seconds. The brakes are
then released (the vehicle will move ac-
cording 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
vehicle from rolling forwards or
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.

Régulateur-limiteur de vitesse : fonction régulateur (X52 - Dacia\
)
ENG_NU_993-5_X52_Dacia_2
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).
This function is an additio-
nal driving aid. However,
the function does not take
the place of the driver.
Therefore, it can under no circums-
tances replace the driver’s responsi-
bility 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 slip-
pery roads (black ice, aquaplaning,
gravel) and during bad weather (fog,
rain, side winds etc.).
There is a risk of accidents.
The cruise control function
is in no way linked to the
braking system.
Controls
1 Main “On/Off” switch.
2 Cruising speed activation, storage and increase switch (+).
3 Decreasing cruising speed (-).
4 Activation with recall of saved crui- sing speed (R).
5 Switch the function to standby (with cruising speed saved) (O).

Switching off the function
The cruise control function is deactiva-
ted if you press switch 1 : in this case
a speed is no longer stored. The two
instrument panel warning lights
 and
 go out to confirm that the function is
deactivated.
Returning to the cruising speed
If a speed is stored, it can be recalled,
once you are sure that the road condi-
tions are suitable (traffic, road sur-
face, weather conditions, etc.). Press
switch
4 (R) if the vehicle speed is
above 20 mph (30 km/h).
When the stored speed is recalled, acti-
vation of the cruise control is confirmed
by the illumination of the
 warning
light.
NB: if the speed previously stored is
much higher than the current speed,
the vehicle will accelerate more rapidly
to reach this threshold.
When the cruise control function is
put on standby, pressing switch 2
(+) reactivates the cruise control
function without taking into account
the stored speed: it is the speed at
which the vehicle is moving that is
taken into account.
Putting the function on
standby
The function is set to standby if you:
– use the switch 5 (O);
– the brake pedal;
– depress the clutch pedal or shift into neutral if the vehicle has an automa-
tic gearbox.
In all three cases, the cruising speed re-
mains stored and the message “MEM”
appears on the instrument panel.
Standby is confirmed when indicator
light
 goes out.
CRUISE CONTROL/SPEED LIMITER: cruise control function (4/4)
Putting the cruise control
on standby or switching it
off does not cause a rapid
reduction in speed: you
must brake by depressing the brake
pedal.

OperationSwitch on the ignition.
The display on the instrument panel
switches on.
If neutral ( N) is displayed, start the
engine but do not depress the accel-
erator.
If any gear other than neutral is en-
gaged, N flashes on the display; press
the brake pedal and place the lever in
position N. Start the engine.
NB: Do not attempt to start the engine
by pushing the vehicle if the battery is
flat (the display remains off when the ig-
nition is switched on).
Under certain conditions, the engine
starter may take some time. Keep the
key in the starting position.
Starting
Moving forwards (starting in neutral)
The gear display shows N then A.
With the brake pedal depressed, posi-
tion the selector lever to D.
Release the brake pedal: – The engine’s idle speed is suffi-
cient for parking manoeuvres.
– Accelerate gently to move for-
wards. Reverse gear
(from neutral, with the
vehicle stationary)
With the brake pedal depressed, posi-
tion the selector lever to R. The letter R
appears on the display.
Release the brake pedal:
– The engine’s idle speed is suffi-
cient for parking manoeuvres.
– Accelerate gently to reverse.
There is a beep when reverse gear is
engaged.
You may shift from reverse gear to a
forwards gear by pushing the lever to D
once the vehicle is stationary.
Note: When the vehicle is stationary,
you must depress the brake pedal to
engage a gear. Otherwise, warning
light
Ó will come on.
SEQUENTIAL GEARBOX (2/6)
Exactly like a vehicle
equipped with a manual
gearbox, a vehicle equipped
with a sequential gearbox is
unable to prevent the vehicle from
rolling on a slope if the handbrake is
not applied or the brake pedal con-
stantly depressed.

Driving in manual mode
This mode can be activated at any time
when driving by pushing the lever to po-
sition M.
To shift up a gear, simply push the se-
lector lever backwards without neces-
sarily releasing the accelerator.
To shift down a gear, simply push the
selector lever forwards without neces-
sarily releasing the accelerator. The system will not tolerate a series
of up or down changes that cause the
engine to underrev or overrev.
By pushing the lever backwards twice,
you can move up two gears at a time
(except if under-revving). By pushing
the lever forwards twice, you can move
down two gears at a time (except if
over-revving).
When decelerating with the foot off the
pedal, the gears will automatically drop
to the low engine speed limit to avoid
stalling. The vehicle may be kept sta-
tionary (stop, red light etc.) by depress-
ing the brake pedal without shifting into
neutral N.The vehicle will move off again:
– either slowly, if you release the brake
without accelerating (e.g. when in a
traffic jam),
– or quickly, if you release the brake and accelerate.
Note: Neutral N may only be selected
when the vehicle is being driven or is
stationary or without touching the brake
pedal.
If the engine speed is too high or too
low, the system will choose the opti-
mum gear.
Manual mode can be deactivated and
reactivated at any time with the engine
running by moving the lever to position
D and respectively to M.

Driving in automatic mode
Each time the ignition is switched on,
starting in neutral, place the lever to D
to be able to shift directly to automatic
mode.
The letter A appears on the display.
The vehicle is controlled using the ac-
celerator and the brake. Gears will
change automatically at the correct
moment and at a suitable engine speed
because automatic mode takes into
consideration the road surface and the
chosen driving style.
Note:
Automatic mode takes account of:
– the position and speed of depression of the accelerator pedal to assess
driving style and select the optimum
gear,
– action on the brake pedal, to com- mence engine braking in preparation
for a downshift.
When stopped at traffic lights, with the
gear engaged, you can keep the ve-
hicle stationary by pressing the brake
pedal without changing to neutral N.
The vehicle will move off again:
– either slowly, if you release the brake
without accelerating (e.g. when in a
traffic jam),
– or quickly, if you release the brake and accelerate.
Economical driving
When driving, always leave the lever
in position D , keeping the accelerator
pedal lightly depressed to ensure auto-
matic gear changes at a lower engine
speed.
SEQUENTIAL GEARBOX (4/6)
Accelerating and overtaking
– slowly depress the accelerator pedal to accelerate gradually,
– to obtain maximum vehicle per- formance regardless of the mode
selected (automatic or manual),
quickly depress the accelerator
pedal beyond the kickdown point.
The speed with which you depress
the pedal will allow you to downshift
according to the vehicle’s capabili-
ties.
If the engine is being overrevved or
underevved, the system will select
the optimal gear.

Parking
When the vehicle is immobilised
– on a flat stretch of road, engage the
handbrake then switch off the igni-
tion,
– on a slope, it is possible to keep a gear engaged by positioning the
lever to position D or R, engage the
handbrake and switch off the igni-
tion.
Bleep
Never leave the vehicle with the engine
running when in gear. For safety rea-
sons, you will hear an intermittent
beeping sound when you open the door
if you have not shifted into neutral.
SEQUENTIAL GEARBOX (5/6)
An impact to the underside
of the vehicle (e.g.: striking
a post, raised kerb or other
street furniture) may result
in damage to the vehicle (e.g.: de-
formation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap-
proved Dealer.
Special circumstances
– If the bends and road surface do
not allow you to stay in automatic
mode (e.g. in the mountains), we
recommend that you change to
manual mode. This will prevent the
automatic gearbox from changing
gear repeatedly when climbing, and
permit engine braking on long de-
scents.
– On a slippery surface or surface
with little grip, change to manual
mode M and select second gear
before accelerating to avoid wheel-
spin.
In very cold weather, the system
may delay the gears from being
shifted while the engine reaches the
right temperature.
