“SAFETY FEATURES”

Active Cruise Control: is an advanced version of conventional cruise control systems. After setting the chosen speed and pre-set distance, radar measurements allow you to maintain a pre-set distance between your vehicle and the vehicle ahead in highway driving. As soon as sensors determine you are closing in on a vehicle ahead, the system automatically slows down to retain your pre-set distance. Once the distance has increased back to the chosen limit the system automatically accelerates to return your vehicle to its pre-set speed.

Active Knee Protection: is a special airbag designed to protect front-seat occupants’ knees in the event of a severe impact. It also reduces the amount of dash space that would have been taken up by a knee-protection system using dash-padding only.

Active Roll Stabilization: Is an "active" suspension control system design to reduce body roll in cornering, resulting in improved handling. Whenever entering a corner, "lateral acceleration" is generated. Sensors read the level of body roll and communicate with the ECU or central "brain" which then processes this signal and coordinates various systems to respond. As a result, ARS actively generates resistance to body roll by twisting the front and rear anti-roll bars appropriate to the situation.

Active Steering: This invaluable steering enhancement increases agility and directional stability in fast-moving traffic or on twisty roads, giving you greater control in virtually all driving situations. Active Steering achieves these driving enhancements by measuring the vehicle speed and other operating conditions, and then electronically varying the steering ratio.

Adaptive Headlights: They automatically swivel in the direction of the road ahead - even up hills and around curves. Sensors measure the vehicle’s velocity, direction and yaw. This information, combined with the movements of the steering wheel, is fed into an on-board computer. Based on this data, the system calculates the direction in which the vehicle is heading, and automatically points the headlights in that direction.

Air - Bags: In a frontal collision they deploy within a blink of an eye to supplement the lap and shoulder belts to reduce further injury. Many new models meet a federal mandate to include weight sensors in the front passenger seat. If a passenger is too small, the air bags must turn off or deploy lightly.

Anti - Lock Brakes: Helps maintain steering control under difficult braking and helps prevent wheel lock - up.

Chassis Stability Control: provides remarkable tenacity on slippery road surfaces. Sensors monitor front wheel rotation and steering wheel angle, yaw sensor and speedometer reading. If the system senses over- or under steer, it modulates engine power and can apply brakes individually to help keep the vehicle under control and going in the intended direction.

Climate Zone Ventilation: Electronic climate zone controls allow the driver to select a lower air temperature for around the head and chest than in the foot well. With automatic recirculation control, when a sensor detects certain pollutants in the air, such as carbon monoxide or ethanol, it automatically switches to recirculating air. Twin active-charcoal micro-filters significantly help reduce air pollutants, such as dust and bacteria, and odors, from entering the cabin.

Corning Lamps: These lamps prove side view illumination when turning which are activated by the turn signal.

Crush Zone: Designed to absorb and dissipate energy in a major impact.

Daytime Driving Lamps: Enhances visibility while driving at dawn or dusk.

Electronic Stability Control: Systems, which can help prevent crashes by applying brakes to individual wheels to keep a vehicle on track.

Elliptical Projection Beams: Have an optical ground lens that provides a whiter and more focus beam to prevent glare to on coming traffic.

Energy Absorbing Bumpers: Are designed to flex and minimize body damage.

Energy Absorbing Steering Column: In the event of a frontal impact it is designed to compress.

Four Wheel Disc Brakes: Provide excellent stopping distances with minimal brake fade.

Front And Rear Stabilizer Bars: Helps to minimize body lean in turns.

Halogen Headlights: Provides a brighter and clearer beam compared to a sealed beam headlight.

Heated Outside Mirrors: Helps to ensure visibility by removing mist.

Lane Departure Warning (LDW) system: Alerts drivers of an unintended movement of the vehicle out of a designated traffic lane. The new system which uses a small camera, speed sensor, an indicator and an audible warning buzzer.
The system recognises lane markings through the use of a small camera mounted behind the rear view mirror. The camera’s signal and the vehicle’s speed are sent to the microprocessing unit, which combines the information to calculate both the distance between the vehicle and the lane marking and the lateral velocity to the lane marking. A judgment is then made as to whether the vehicle is moving out of the lane (depending on the distance and lateral velocity to the lane).
The system is disabled by driver activation of the vehicle’s turn signals, which informs the system’s control unit of intended lane changes. The system also features a manual cancel switch, which allows the driver to turn the system off when desired. The system automatically resets when the vehicle is restarted.
If it is determined that the vehicle is leaving the lane, both visual (indicator light located on the instrument panel) and audible (buzzer) warning signals are generated, alerting the driver to take corrective action. The system will not operate if the camera can’t detect the lane markers or if vehicle’s speed is below 45 miles per hour.

Navigation System: With the Navigation system, you can always see where you are. Using GPS (global positioning satellite), the onboard Navigation system pinpoints your vehicle's location and displays bright, clear graphics on your instrument panel.

Night Vision: Is not meant to replace a driver’s view out of the windshield, it gives drivers additional visual information beyond what their eyes are capable of seeing. Night Vision helps the driver detect potentially dangerous situations beyond the normal headlight range.

OnStar: Using innovative technology, OnStar can provide you with the latest information and assistance. Just press the blue OnStar button and you'll be connected to the OnStar Center where trained, knowledgeable, live Advisors are ready to help. Plus, some OnStar vehicles give you the ability to send and receive calls. Like you would using a wireless phone minus inconvenient dialing.

Park Distance Control: Uses ultrasonic sensors in the front and rear bumpers to help you judge the distance to other cars and unseen objects when parking. The beeping becomes faster as your bumper approaches the object, turning into a constant tone when the distance is less than 12 inches.

Rear Parking Assistance: Operational while the vehicle is in reverse, rear parking assistance uses sonar to detect stationary objects up to five feet behind the vehicle, if they are at least three inches wide and at least ten inches high.

Rear Window Defogger: Helps to ensure visibility.

Safety Cage: Helps to protect the passenger compartment by dissipating the energy in a uniform manner in a high impact so as not to harm the occupants.

Side Head Protection System: Is an inflatable tubular structure to protect the heads of a vehicle’s front-seat occupants. Operating in conjunction with the side airbags, the system provides front seat occupants with outstanding protection in the case of severe side impact. It helps protect the head from hitting the side window and being hit by objects penetrating the side window.

Steel Door Guard Beams: High strength beams run inside each door to help protect the occupants in a side impact.

Tire Pressure Monitoring : As air leaks, tire pressure decreases, and the tire rotates faster. ABS sensors on the wheels detect a change in wheel rotation speeds, which signifies a change in the roll radius, or pressure level, of the tires. A warning light in the instrument panel notifies the driver of the pressure loss. In case of significant pressure loss, a warning buzzer sounds.

Traction Control: Helps to eliminate slippage in inclement weather to aid in better traction.
