2005 BUICK LaCROSSE: SAFETY AND SECURITY

The 2005 Buick LaCrosse has a comprehensive list of features designed to make it one of the safest midsize vehicles on the road.

Key safety and security items standard on all 2005 Buick LaCrosse models include:

- A frontal dual-stage air bag system that provides enhanced protection to driver and front-seat passenger.
- A strengthened body structure from the rocker panels upward.
- An aluminum engine cradle engineered with crush characteristics to absorb impact energy and help direct it away from occupants.
- GM's OnStar safety and security system, which provides driver assistance using Global Positioning System satellite technology.
- PASSLock III theft deterrent system with engine immobilizer.

Newly available safety and security features include:

- Side curtain air bags that deploy fully from the roof rail to the vehicle beltline, which help protect the head and chest of front and rear outboard occupants in the event of a side impact.
- GM's StabiliTrak electronic stability enhancement system (CXS only). StabiliTrak helps drivers maintain control of vehicles during certain difficult driving conditions such as ice, snow, gravel, wet pavement and uneven road surfaces; as well as in emergency maneuvers.
- Ultrasonic Rear Parking Assist, which detects certain stationary objects behind the vehicle as low as 10 inches from the ground, and as far back as almost 5 feet.
- A factory-installed remote starting system - a first for Buick - with a range of up to 500 feet and automatic ventilation system control.

Frontal air bag system

One of the new LaCrosse's most significant safety features is a frontal air bag system that works with the safety belt system to provide increased protection for all front occupants, including smaller adult females.

The system uses dual-stage inflators, depending on the speed and severity of an impact. The first stage deploys the air bag with less force in lower-speed, less severe crashes. In moderate-to-severe impacts, both stages are activated. Knee bolsters on the lower portion of the instrument panel help provide added leg protection.

Side curtain air bags available

Side curtain air bags are available for the first time on a midsize Buick. The optional side curtain air bags, which act like a protective curtain when deployed, are mounted to the roof rail and deploy downward to cover the front and rear door windows and B-pillar. These air bags help protect the heads and chests of outboard occupants in the event of a side impact.

Additional interior impact protection is provided by energy-absorbing material within the front, center and rear roof pillars.

Safety belt system

Safety belts remain the primary and most effective form of occupant protection. All air bags provide the most effective protection when used with lap and shoulder belts. In addition to the dual-stage air bag system, several advances have been made to the safety belt system for all 2005 Buick LaCrosse models.

A lap and shoulder belt combination is standard in the center rear occupant position. Pretensioners in the front safety belts help minimize forward movement during a frontal impact. The pretensioner system helps remove belt slack during a collision using a small pyrotechnic device attached to the front safety belt buckle. A sensing and diagnostic module within the air bag system triggers the device.

The safety belt systems have a retractor design that uses a twist shaft in the take-up reel to help reduce chest loading by allowing more shoulder belt payout during the "ride down" part of a crash. The LaCrosse also is equipped with child seat attachments in the three rear seat positions. The system, called LATCH (Lower Anchors and Tethers for CHildren), has six metal hooks to help simplify the installation of child safety seats.

Body structure enhancements

Many structural enhancements have been engineered into the new body shell and underside of the LaCrosse to help provide maximum occupant protection and minimum intrusion under a wide range of collision conditions. LaCrosse's "safety cage" structure includes:

- A one-piece cross-car magnesium beam behind the instrument panel. The beam is lightweight yet provides enhanced front- and side-impact protection, as well as additional body rigidity.
- A B-pillar made of high-strength steel provides enhanced side-impact protection from the rocker panels to the roof rails.
- Pre-cast structural foam added to the roof rail across the top of the B-pillar and partially down the pillar aids impact absorption.
- An interlocking clevis on the lower portion of the rear door and inner sill that latches the door to the rockers and wheelhouse stampings helps minimize side-impact intrusion.
- A heavy gauge steel crossbar under the rear seats uses a straight cross-car design instead of an angled stamping for added support and protection.
- High-strength steel reinforcements inside the rocker panels just below the doors helps increase protection during front, side and rear impacts.
- High-strength steel door beams with a hat-shaped design aids side-impact protection.

Engine cradle, front structure and bumper designs

The new LaCrosse models use an engine cradle made of welded aluminum extrusions. The cradle weighs about 20 pounds less than the welded steel assembly used on the previous generation of midsize Buicks, while providing improved energy absorption and crush characteristics to help reduce and manage impact forces away from the passenger compartment. The cradle supports the engine, transaxle, steering and front suspension.

To accommodate the additional power and performance of the high-output 3.6L VVT V-6, the LaCrosse CXS has strong lower frame rails, frame reinforcements and a heavy-gauge No.1 crossbar.

In addition, the front and rear bumpers on all LaCrosse models are made of high-strength steel, which weighs less while still meeting all applicable standards.

A strong safety foundation

Besides significant enhancements to its body structure and active passenger protection systems, LaCrosse has numerous other safety features, all which work together to help provide even higher levels of safety and security. Among them are an all-new brake system, traction control, StabiliTrak, recalibrated steering systems and improved lighting.

All-new four-wheel-disc brake system

All LaCrosse models have a brake system that provides greater stopping power, increased durability, an improved pedal feel and smoother operation as compared to the previous generation of midsize Buicks. The Delphi system has rear discs with larger front rotors, stiffer calipers and a larger power booster unit.

An anti-lock braking system (ABS) is optional on the LaCrosse CX and CXL, and standard on the CXS. This Bosch 5.3 Series system reads input from speed sensors at each wheel to help prevent wheel lockup during hard braking and to help the driver maintain steering control. The system also incorporates an electronic brake force distribution feature, which monitors and adjusts front to rear brake pressure balance as needed, and prevents rear wheel lockup when the vehicle is lightly loaded.

Traction control

Three versions of traction control are offered on LaCrosse for 2005, each one providing added safety and driver control in a variety of road and weather conditions.

- CX and CXL models are available with an engine-based enhanced traction control system that reduces engine power depending on the rate of front wheel slippage. Initially, the electronic brake control module (EBCM) sends a message to the powertrain control module (PCM) to retard engine spark. If excess wheel slippage is detected, the PCM can shut fuel delivery to up to three engine cylinders or even shift the transaxle into second gear until traction is restored.
- GM's full-range traction control system is standard on the LaCrosse CXS. In addition to electronic engine management, this system applies the brakes at one or more wheels as required to restore traction.
- For optimum vehicle control especially during emergency or evasive maneuvers, GM's StabiliTrak stability enhancement system is available on the LaCrosse CXS, a first for any Buick midsize car.

StabiliTrak uses sensors to detect the direction the driver is steering by "reading" the steering wheel position and the vehicle's response to steering wheel input.

When the system determines that the car is not responding adequately to steering commands, it then works to help bring it on course by automatically reducing engine torque and applying precise amounts of pressure to front right or left brakes. These brake and engine interventions, which require no driver activation, help realign the vehicle's actual path with that being steered by the driver.

Steering systems

The steering systems on all Buick LaCrosse models have been tuned for precise control and on-center feel at higher speeds. All models use a T-bar, or shaft, inside the steering gear for increased control, and a neoprene isolator on the I-shaft for quieter operation and better overall feel. LaCrosse CXS models have as standard Delphi's Magnasteer system, which uses a computer-controlled electromagnet to adjust steering effort, depending on vehicle speed. In low-speed maneuvers such as parking, it provides more assist for easier effort. Assist is reduced at higher speeds for a more direct response.

Improved headlamp performance

A new headlamp system with higher-intensity halogen bulbs over its predecessors give LaCrosse a 35-percent improvement in overall low-beam lighting performance, for better forward visibility during nighttime driving. Additionally, the amber front parking lamps now function as daytime running lamps (DRLs), shown to reduce both daytime vehicle-to-vehicle and vehicle-to-pedestrian crashes. Fog lamps, standard on CXS, now use high-intensity halogen bulbs in place of reflector optics for improved down-the-road visibility during inclement weather.

OnStar services

LaCrosse is equipped with OnStar, including a one-year subscription to the OnStar Safe & Sound plan. OnStar is the leading provider of in-vehicle safety, security and information services in the U.S. and Canada. Using the Global Positioning System (GPS) satellite network and wireless technology, OnStar services include automatic notification of air bag deployment, stolen vehicle location, remote door unlock, emergency services dispatch, roadside assistance, remote diagnostics, route support, convenience services and OnStar Concierge. OnStar Personal Calling allows drivers to make and receive hands-free, voice-activated phone calls through a nationwide network in cooperation with Verizon Wireless. Virtual Advisor (U.S. only) gives subscribers access to personalized information in a hands-free, voice-activated manner with no screens or displays.

Yup.. my 2000 has a side-impact airbag. Even has that label that reads "AIRBAG" on the side. Believe me, I had the car a month before I even realized I had it. LOL :lol:
Only thing my 2000 doesn't have is the head curtain. the 2004's have them now though.
