Maintaining proper tyre pressure is paramount for optimal safety, performance, and fuel economy. The tyre-pressure monitoring display system standard for Jeep® Grand Cherokee Limited and SRT8 models features tyre-valve stem-mounted sensors that monitor individual tyre pressures for all four rotating tyres and warn if pressure is too low or too high. You’ll know your tyres are ready to hit the road (tyre pressure monitoring warning without display on Laredo).
