technical data anti-lock braking system abs with cornering brake control cbc d1 cornering brake control makes the car easier to control in extreme situations particularly when braking sharply on a bend it is particularly effective when carrying out emergency procedures such as avoiding a child s ball that s rolled out from the kerb the system works by sensing the different rotational speeds of the individual road wheels and co-ordinating the level of braking pressure applied to each wheel cbc is an integral part of astra s comprehensive abs sport switch the sport switch standard on design 2.0i 16v turbo and all sri models improves the responses of both the steering and throttle giving the driver crisper initial acceleration and sharper more direct turn-in when cornering on vehicles fitted with automatic transmission the sport switch also controls the transmission sport mode ids-plus with continuous damping control cdc d4 the interactive driving system ids-plus chassis ­ available on sri and design models ­ offers the astra driver an even more sporting driving experience thanks mainly to the electronic control of the suspension pressing the sport switch activates the cdc function ­ cdc monitors the roll pitch and yaw of the car and changes the rate of damping on each wheel to optimise the handling selectively stiffening the suspension this means the vehicle will exhibit a reduced rate of roll and pitch making it more responsive during direction changes and more settled during the braking/turn-in/acceleration transition when cornering cdc is a major breakthrough in the astra segment d4 d1 stopping distance at 60mph actuating time 150 milliseconds emergency brake assist eba d2 emergency brake assist detects the urgency with which the brake pedal is pressed and rapidly increases the pressure to the maximum the system can provide shortening stopping distances it also enhances pedal feel reduced stopping distance with eba stopping distance without eba adaptive forward lighting afl adaptive forward lighting is a sophisticated new lighting system that allows astra drivers to see around corners first seen on signum and vectra this optional bi-xenon system employs two main functions curving light d5 controlled by a combination of steering wheel movement and sensors for the vehicle s speed and yaw angle the curving light function allows the headlight beam to move up to 15 degrees left or right of the straight ahead position this ensures the light is always following the trajectory plotted by the front wheels rather than simply pointing straight ahead motorway light d6 at speeds above 65mph afl raises the dipped headlight beam to extend the range of vision for increased safety at higher speed the beam automatically returns to its normal position when the car falls below that speed astra is one of the first cars in its class to offer such technology d2 electronic stability programme esp-plus d3 working in conjunction with the car s traction control system tc-plus esp-plus provides enhanced yaw compensation during understeer or oversteer the system works by monitoring the front and rear of the car comparing their respective directions of travel going in to the bend with the input received through the steering wheel if the vehicle starts to slide it applies corrective braking to the appropriate wheel or wheels compensating for the understeer and helping you regain control more rapidly d5 d3 d6 s.12 s.13
