This high tech "guardian angel" provides owners with round the clock assistance covering a range of situations from the inconvenience of lost keys, right through to checking on the safety of occupants, or deploying emergency services, if your vehicle's airbags or seatbelt pretensioners are activated.

Previously only available as a factory-fitted option, the system uses integrated in-vehicle GSM mobile phone network and global positioning satellite technology to provide full-time assistance.

In an emergency, an SOS button on the rear vision mirror will immediately connect the driver to Holden Assist Ultra, who can contact emergency services.

If your car is stolen, Holden Assist Ultra can track the vehicle's movements and safely disable the engine after instruction from the police. Or if your vehicle's alarm is triggered, Holden Assist will contact you and despatch the police if required.

A new Holden Assist Ultra feature also allows owners to send text messages from Holden Assist's web portal to the vehicle's centre console screen.

GM Holden Director of Marketing Philip Brook said existing VE Commodore owners can now fit Holden Assist Ultra as an accessory giving them added peace of mind in a wide range of situations.

“Our customers appreciate the extra level of protection from Holden Assist Ultra, especially when considering their family's safety. It's easy to use, integrates seamlessly into Commodore's controls and the 24/7 contact with Holden Assist operators gives customers extra peace of mind,” he said.

“If you or a family member is out driving on their own, or living in a remote area, it is comforting to know that if something goes wrong help is close at hand.”

Holden Assist Ultra currently supports around 5,000 customers and in the last 12 months has unlocked more than 360 cars remotely, detected 17 crashes and tracked 14 stolen vehicles. It has also provided SOS support in over 600 cases.

Holden Assist Ultra is priced at $1,990 plus GST and fitment, and includes three years service. It can be fitted to all VE Commodore sedan & Ute models and WM Statesman and Caprice.
