Sources & notes
- This record describes only the stated 2010 U.S. configuration; it does not represent every trim or year of the generation.
- Dimensions converted from factory-published inches using 25.4 mm per inch and rounded to the nearest millimeter.
- Height uses the base model’s 74.2-inch antenna-inclusive measurement under EPA loaded-vehicle conditions. The sheet separately lists 72.6 inches with side rails and lower Premium-model heights; these measurements are not interchangeable.
- The U.S. brochure identifies standard coil springs and Premium-only rear air suspension. The product information chassis table lists the air system without a grade qualifier; the brochure and pricing release establish the base configuration.
- Model year 2010 uses EPA’s 2008 calculation method; it is not a pre-2008 adjusted record and is not adjusted to the 2017 calculation method.
- The cited dimension table does not explicitly state mirror inclusion in overall width; mirror coverage is unverified.
