ENHANCED SAFETY AND CONVENIENCE MAKE GMC YUKON AND YUKON XL EVEN BETTER TRANSPORTATION CHOICES FOR 2005

Also new to Yukon and Yukon XL models for 2005 is an available DVD-based touch-screen navigation radio. The easy-to-use system employs touch-screen functionality and will map routes wîth 2-D and 3-D full-color map views on a large, 6.5-inch (165-mm) display screen. Once the navigation DVD is inserted and the address entered on the system's screen, a route map is generated and audio commands are provided. (concept carz) Instructions in English and French are available.

The verbal commands tell drivers when to turn and alerts them if they stray from the calculated route; the system automatically recalculates a new route from their current position if they make a wrong turn. Additionally, drivers can instruct the navigation system to plan a route using the shortest path or one using major roads.

Improved fuel economy

Already a class leader in fuel economy, the 2005 Yukon and Yukon XL extend that leadership wîth three enhancements that lead to approximately a 1-mpg fuel economy improvement.

Electric cooling fans

This model year's Yukon and Yukon XL models feature an all-electric cooling system (compared to fan and fan clutch on 2004 models). The all-electric cooling system consists of two 200-watt electric fan packages and an improved dissipation radiator. The new cooling system provides a number of advantages:

* A reduction in parasitic losses due to disengaged fan speed wîth a corresponding increase in combined city/highway fuel economy
* A significant improvement in idle air conditioning performance (driver/passenger comfort) as well as an ability to idle wîth the air conditioning on for extended periods in very high ambient temperatures
* Quieter operation

Regulated voltage control

A new voltage control system monitors the battery's charge status and controls the vehicle's generator to minimize parasitic voltage loss.

Aerodynamic improvements

Other changes designed to improve fuel economy include improved sealing of the vehicles' front end. For example, tow hook openings are now sealed when not ordered on the vehicle. In addition, the center hole in the front air deflector has been sealed, an extension has been added to the front air deflector, and the aerodynamics for the running boards have been improved.

Additional changes

Yukon and Yukon XL's other content changes for 2005 include:

* 17-inch wheels: Últra Bright Polished 17-inch cast aluminum wheels – an all-new appearance – are offered as a stand-alone option for 2005.
