* Factory installed crossbars: These are typically integrated into the vehicle's design and *aren't* adjustable in terms of height or width. They might have adjustments for tightening clamps or securing load bars, but not position.
* Aftermarket crossbars: These are purchased separately and mounted onto existing roof rack mounting points (if your Escape has them) or on the rain gutters using clamps. Adjustment will depend entirely on the specific brand and model of the aftermarket rack. Check the manufacturer's instructions; they usually involve tightening or loosening clamps to secure the bars at the desired position. Some might allow for minor adjustments in bar position fore and aft.
* Thule, Yakima, or other brands' systems: These often use different mechanisms for securing and adjusting crossbars, feet, and towers. Again, consult the owner's manual for your specific brand and model of roof rack.
To get specific instructions, you MUST:
1. Identify your roof rack: Is it a factory-installed rack, or an aftermarket one? If aftermarket, what brand and model is it?
2. Locate the owner's manual: This manual should provide detailed diagrams and instructions on how to adjust your specific roof rack. If you don't have the manual, try searching online for a PDF version using the brand and model number.
Without knowing the specific type of roof rack on your 2009 Ford Escape, it's impossible to provide precise adjustment instructions. The lack of adjustability for a factory rack is common. Aftermarket racks will vary significantly.
