Dacia Bigster

Depending on the vehicle, they may include:

• the ABS (anti-lock braking system);
• emergency brake assist;
• of the electronic stability programESC with understeer control and traction control;
• hill start assistance;
• deceleration speed control;
• multi-collision braking.

ABS (anti-lock braking system)

Under heavy braking, the ABS prevents the wheels from locking, allowing the stopping distance to be managed and keeping control of the vehicle.

Under these circumstances, the vehicle can be steered to avoid an obstacle whilst braking. In addition, this system can increase stopping distances, particularly on roads with low surface grip (wet ground etc.).

You will feel a pulsation through the brake pedal each time the system is activated. The ABS does not in any way improve the vehicle’s "physical" performance relating to the road surface and roadholding. It is still essential to follow the rules of good driving practice (such as driving at a safe distance from the vehicle in front etc.).

Special feature of 4-wheel drive vehicles

In "4WD LOCK" mode, the system may lock the wheels briefly to optimise the braking distance on very wet ground (snow, mud, sand, etc.).

Operating faults:

• and lit up on the instrument panel accompanied by the "Check ABS", "WARNING: Check Braking System" and "Check ESC" messages: this indicates that the ABS, the ESC and the Emergency Brake Assist functions are deactivated. Braking is still provided;
• , , and lit on the instrument panel accompanied by the "WARNING: Braking System" message: this indicates a fault with the braking system.

In both cases, please contact an approved Dealer.

Emergency brake assist with electronic brake distribution

(depending on the vehicle)

This system supplements the ABS and helps reduce vehicle stopping distances.

Operating principle

The system is for detecting an emergency braking situation. In this case, the braking assistance immediately develops maximum power and may trigger ABS regulation.

ABS braking is maintained as long as the brake pedal is applied.

Electronic stability control ESC with understeer control and traction control

Electronic stability control ESC

(depending on the vehicle)

This system helps you to keep control of the vehicle in critical driving conditions (avoiding an obstacle, loss of grip on a bend, etc.).

Understeer control

This system optimises the action of the ESC in the case of pronounced understeering (loss of front axle road holding).

Traction control

This system helps to limit wheelspin of the drive wheels and to control the vehicle when pulling away accelerating or decelerating.

Disabling the ESC function

(depending on the vehicle)

In some situations (driving on very wet ground: snow, mud, sand, etc. or driving with snow chains fitted), the system may reduce the engine output to limit wheelspin. If this is not required, it is possible to deactivate the function by pressing and holding the switch 1.

The warning light on the instrument panel comes on to warn you of this. If you deactivate this function, the traction control system will also be deactivated.

As the electronic stability program ESC with understeer control and traction control provide additional safety, you are advised not to drive with the function deactivated. Get out of this situation as soon as possible by pressing the switch 1 again.

Note: the function is reactivated automatically when the ignition is switched on or when a speed of approximately 31 mph (50 km/h) is exceeded.

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, indicator light flashes on the instrument panel.

Operating faults

If the system detects an operating fault, the and warning lights appear on the instrument panel and, depending on the vehicle, the "Check ESC" message is displayed on the instrument panel. In this case, the electronic stability program ESC with understeer control and traction control are deactivated.

Please consult an authorised dealer if these warning lights remain displayed on the instrument panel after the ignition is switched off and on again.

Disabling the traction control system

(depending on the vehicle)

Hill start assistance

Depending on the gradient of the incline, this system assists the driver when starting on a hill. It prevents the vehicle from rolling backwards by automatically applying the brakes when the driver lifts his/her 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 or P on an automatic gearbox) and the vehicle is completely stationary (brake pedal pressed).

The system holds the vehicle for approximately 2 seconds. The brakes are then released (the vehicle will move according to the slope).

If the system detects an operating fault, the warning light and, depending on the vehicle, the "Check Hill Start Assist" message is displayed on the instrument panel. Consult an approved Dealer.

Hill descent control

This function enables the vehicle speed to be limited without depressing the brake pedal (when driving down a steep hill).

The hill descent control operates between 3 and 19 mph (5 and 30 km/h).

Note: when the vehicle speed exceeds 37 mph (60 km/h), the system is disabled and the warning light disappears.

Multi-collision braking

Multi-collision braking reduces the risk of an additional collision after an accident by temporarily bringing your vehicle to a standstill.
