How to Change Your Jeep from Celsius to Fahrenheit

Changing your Jeep from Celsius to Fahrenheit usually takes about 30 seconds in a settings menu. The problem is finding that menu. If you've been searching for how to change my jeep from celsius to fahrenheit and keep landing on instructions that don't match your screen, you're not doing anything wrong.

Your Jeep's units setting lives inside whichever display system it shipped with, and Jeep has used at least four different ones since 2007. NIST defines both Fahrenheit and Celsius as official temperature scales, and Uconnect software simply toggles between them. Before you touch a single button, figure out which system you're sitting in front of.

Quick Answer

Open Settings on your Uconnect screen. Select Display, then Units. Choose US instead of Metric.

Press OK to save your choice. On a digital cluster, use the steering wheel arrows instead. The change applies instantly to the outside temperature display.

Why Your Jeep's Temperature Units Aren't a One-Size-Fits-All Fix

Jeep hasn't used one infotainment platform across its lineup. A 2015 Wrangler JK, a 2019 Grand Cherokee WK2, and a 2024 Wagoneer all handle temperature units differently, even though the end goal is identical.

On most Uconnect 3 and Uconnect 4 systems, the toggle sits under Settings, then Display, then Units. Uconnect 5 moved it. On some 2022-and-newer models it hides under a Vehicle or Vehicle Settings menu instead.

Three things change the answer:

• Model year and platform
• Uconnect generation and screen size
• Whether the temperature you want to change lives on the touchscreen or a separate cluster

Manual climate control is the exception. If your Jeep has physical hot and cold knobs with no digital readout, there's no units setting to change, because nothing on that panel displays a number.

Your instrument cluster can be a separate story. The Electronic Vehicle Information Center, or EVIC, runs its own menu on many Wrangler, Gladiator, and Grand Cherokee models. That menu has its own units option, and it doesn't always follow the radio.

Aftermarket head units are their own case. They rarely talk to the factory cluster, so changing units on the radio may leave the cluster reading Celsius.

That's why generic advice fails. Identify your system first, then follow the path that matches it. No tools are needed, and no dealership visit is required on factory systems.

The Three Variables That Decide Your Path: Model Year, Uconnect Version, and Display Type

Three variables decide which instructions apply to you. Get these right and the actual change takes about a minute.

Model year matters most. Wrangler JK ran 2007 to 2018 and Wrangler JL started in 2018. Grand Cherokee WK2 ran 2011 to 2021, and the WL replaced it in 2022.

Uconnect version is the second variable. Uconnect 3 and 4 share a similar menu tree. Uconnect 5 reorganised the layout when Jeep rolled it out, so 2021 and 2022 vehicles can differ even within the same model.

Display type is the third. Screens come in 5-inch, 7-inch, 8.4-inch, 10.1-inch, and 12-inch sizes. The 8.4-inch Uconnect 4 is the most common setup in used Jeeps, and it follows the older path.

Higher trims with a full digital cluster let you change units through the steering wheel buttons. Analog clusters with a small centre screen usually mirror whatever the head unit is set to.

Not sure which you have? Open Settings and tap Software Information. The version string tells you the generation.

Your Decision Tree: Uconnect 3/4/4C, Uconnect 5, EVIC Cluster, or Manual Climate Panel

Work down this list until one line matches your screen. Then jump to the matching steps in the next section.

• If you have a 5-inch, 7-inch, or 8.4-inch Uconnect 3 or 4 display, go to Settings > Display > Units. Pick US.
• If you have a 10.1-inch or 12-inch screen with the newer tile layout, tap Settings > Units. Some builds put it under Vehicle > Settings > Units.
• If you have a digital cluster with steering wheel controls, press the up/down arrows until Settings appears. Then choose Units.
• If you have manual climate knobs and no digital temperature readout, there's nothing to change.
• If you fitted an aftermarket radio, the factory cluster won't follow it.

Some Jeeps have both a touchscreen setting and a separate cluster setting. Changing one won't always change the other. If the outside temperature still reads in Celsius after the head unit change, look for a second units menu in the cluster.

Two conditions block the menu on nearly every Jeep. The vehicle must be in Park, and the ignition must be in Run or Accessory. If your screen greys out the options, one of those two is wrong.

If nothing matches any line above, your head unit may be running older software. A Uconnect software update is a dealer service, and it's the honest answer when the menu genuinely isn't there. In our research, that's rare on 2018-and-newer vehicles.

Step-by-Step: Changing Celsius to Fahrenheit on Each Jeep System

Each path below takes under a minute. Pick the one that matches your decision tree result.

Uconnect 3 and Uconnect 4:

1. Park the Jeep and start the engine, or push the ignition to Run.
2. Tap Settings on the touchscreen.
3. Tap Display.
4. Tap Units.
5. Select US.
6. Confirm, then exit. Check the outside temperature display.

Uconnect 5:

1. Park the Jeep with the ignition in Run.
2. Tap Settings.
3. Tap Units. If it isn't there, tap Vehicle, then Settings, then Units.
4. Select US.
5. Confirm and back out of the menu.

EVIC or digital cluster:

1. Park with the engine running.
2. Use the steering wheel arrow buttons to scroll to Settings.
3. Press OK.
4. Scroll to Units.
5. Select US.

Once you're done, glance at the cluster and the climate panel separately. They pull from different modules on some models, so confirm both actually switched.

If your Jeep has dual-zone automatic temperature control, the driver and passenger sides share one units setting. You won't need to change them individually.

One practical note. Aggregate owner reports show the units reverting after a battery disconnect or a software update on certain 2019 to 2021 models. If that happens, just repeat the same steps.

If the change sticks, you're done. If it doesn't, the next section covers the reasons why.

Mistakes That Keep Your Jeep Stuck in Celsius (and How to Fix Them)

Why does the outside temperature still read in Celsius after I changed it?

Because the cluster and the radio pull their units from separate modules on some models. Change the head unit, then check the EVIC menu as well. If the climate panel shows a number, that's a third place to look.

One setting doesn't always cover all three.

Why are my units options greyed out?

Your Jeep isn't in Park, or the ignition isn't in Run or Accessory. Those two conditions unlock the menu on nearly every Uconnect build. Sitting in Drive with the screen awake won't cut it, even if the rest of the menu responds.

Why did my units switch back after a battery change?

Because the settings reset when power is cut. As of 2026, owner reports still flag this on certain 2019 to 2021 models after battery swaps and Uconnect software updates. Repeat the same steps and you're back to Fahrenheit.

It's a nuisance, not a fault.

Watch out for these too:

• Picking "Metric" when you wanted US customary units. Metric means Celsius and kilometres.
• Confusing US gallons with Imperial gallons when you adjust fuel economy units at the same time.
• Adjusting settings while driving. Pull over first. Distraction behind the wheel is a real risk, and NHTSA guidance on distracted driving covers screen interactions.
• Expecting an aftermarket head unit to sync with a factory cluster. It usually won't.

The one that trips people up most is assuming there's a single fix. There often isn't. Check both displays before you assume the job failed.

Jeep Model Cheat Sheet: Wrangler, Grand Cherokee, Cherokee, Compass, Renegade, Gladiator, Wagoneer

Most Jeep models follow one of three paths. Use the table below to find yours, then follow the matching steps from earlier.

If you drive a Wrangler JL built after 2021, expect the newer menu tree. Jeep reorganised it when Uconnect 5 arrived, so older YouTube walkthroughs won't match your screen.

Grand Cherokee owners get the widest spread. A 2014 WK2 and a 2024 WL share a nameplate but not a menu. Always check the year before following any guide.

Patriot, Liberty, and Commander models built before 2013 mostly predate Uconnect 3 in its current form. On those, temperature units often can't be switched at all from the factory screen.

Not sure which generation you have? Check the software version. Aggregate owner reports show that a version string starting with 8.4 indicates Uconnect 4, while newer five-digit strings point to Uconnect 5.

One last check. Wagoneer and Grand Wagoneer models with Google built-in sometimes place Units under a separate Google account settings panel. If Settings > Units isn't there, look under System.

FAQs: Jeep Temperature Units, Uconnect Settings, and Cross-Border Confusions

How long does it take to change my Jeep from Celsius to Fahrenheit?

About 30 seconds once you find the menu. Parking, tapping through Settings, and confirming takes under a minute on every Uconnect generation. Digital clusters with steering wheel navigation run about the same.

The only slow part is working out which system you have.

Can I change temperature units without the engine running?

Yes, as long as the ignition is in Run or Accessory. The menu stays greyed out in Off. Some models also need the transmission in Park.

If the options look locked, those two conditions are the reason nearly every time.

Why does my Jeep still show Celsius after I changed the setting?

Because the cluster and the radio use separate modules. Changing the head unit doesn't always update the Electronic Vehicle Information Center. Check the EVIC menu on the steering wheel too.

If a digital climate panel shows numbers, check that as well.

Will a Uconnect software update reset my units?

It can. Owner feedback on 2019 to 2021 models reports units reverting to Metric after updates and battery disconnects. The fix is the same as the original change.

Repeat the steps and your Fahrenheit setting returns in under a minute.

Does an imported Canadian Jeep need metric for US registration?

No. The US uses Fahrenheit and miles per hour for everyday driving, and no state requires metric displays for registration. Canada uses Celsius, which is why imported Jeeps often arrive reading that way.

Switching to US units is a preference, not a legal requirement.

Can a dealership change the units for me?

They can, but it's rarely worth paying for. The setting lives in a menu you already have access to. In our research, dealer diagnostic fees for this kind of request often start around $100 or more.

Save it for the case where the menu genuinely doesn't exist.

Final Decision Guide: What to Try First (and When to Visit the Dealer)

Start with the touchscreen. Nine times out of ten, the answer is Settings > Display > Units on Uconnect 3 and 4, or Settings > Units on Uconnect 5.

If that doesn't work, check the cluster. Use the steering wheel arrows to reach Settings, then Units. Some Jeeps keep the two displays independent, so both need attention.

If neither menu exists, confirm your conditions first. Park the vehicle. Put the ignition in Run or Accessory.

Greyed-out options almost always trace back to those two.

Then check the software version. Older Uconnect builds are the honest reason a Units menu can be missing. That's the one scenario where a dealer software update makes sense.

Aftermarket head units sit outside this whole system. They won't push a units change to the factory cluster, and no menu on the radio will fix that. If your cluster reads Celsius with an aftermarket radio fitted, that's expected behaviour, not a fault.

One thing worth doing while you're in there. Check your distance, fuel economy, and tire pressure units at the same time. Mixing Fahrenheit with kilometres per hour gets confusing fast, especially for towing and off-road temperature monitoring.

That covers it. Find your system, follow the matching path, and confirm both displays switched. Most Jeep owners finish in under a minute once they know which screen they're dealing with.
