## Jeep specifications at a glance

## How we verify Jeep specifications

Every figure on these 2 nameplates is checked against owner's manuals, Jeep service documentation, and NHTSA recall and complaint records, then labelled with how confident we are in it. Where a specification is safety-relevant and we could not confirm it to that standard, the page says so rather than guessing.
