we would both be assuming that the scroll arrows and the OK button on the left side of your steering wheel are functioning properly. I know it's a stretch but it is possible that you have a problem. I'm not in my vehicle and working from memory... Press the down arrow under the OK until an icon appears that looks like the front of a vehicle then the right arrow which should cycle through voltage, temp, tire pressure and DEF which is shown as a percentage. this might not be accurate but if you keep pushing ups down rights and lefts you will stumble on it... Once again I'm assuming nothing is wrong with your vehicle. Even if your salesman doesn't know they must have someone in service who can verify your controls aren't malfunctioning.Perhaps not, the salesman didn't know Jeep made a diesel. I was hoping to get some useful information form this site, maybe there is still hope.
On the Summit, the DEF level is indicated on the dash by toggling through all the display options with the steering wheel button (+). The vehicle speed posts at the top and the DEF level has its own reading towards the bottom with a digital gauge reading and a percentage reading.Perhaps not, the salesman didn't know Jeep made a diesel.
