On electricity: 49 MPGe combined (52 city / 45 highway), 22 miles of electric range, 68 kWh per 100 miles. EPA blended gas-and-electric rating: 28 MPG.

Source: U.S. EPA and Department of Energy, fueleconomy.gov. MPG is miles per gallon (MPGe for electric operation). Plug-in hybrids list gasoline-only MPG with the electric rating underneath. Annual fuel cost assumes 15,000 miles a year at the EPA's fuel-price assumptions, so yours will differ. Range is total driving range on a full tank or charge.

Cold tire pressure
Not a single number: the owner's manual refers to the tire and loading placard (driver's side door opening), which lists the pressures for your exact tire size and load.
Spare
The sheet lists no spare; the manual describes a matching full-size spare with a pressure sensor, a compact spare, or a tire service kit instead of a spare, depending on equipment.
Lug nut torque
130 ft-lb (176 N·m), M14 x 1.50 thread, 22 mm socket
Pressure monitor
A tire pressure monitoring system warns when a tire is low.

Sizes and pressures vary by trim, wheel package and load: check the placard on your vehicle and the tire sidewall. Sizes from the manufacturer's specification sheet (2021 Jeep Wrangler 4xe Specifications, 2021 Jeep Wrangler Specifications). Pressure and spare notes from the owner's manual.

Salt, snow and hills: the data

Reading the 2021 Wrangler data for Great Lakes roads

We read the 2021 Wrangler owner data, service schedule and spec sheets with Michigan driving in mind: frozen starts, salted highways, cratered streets and hills. These are the figures worth acting on.

Sidewall height versus broken pavement

Squalls off Lake Michigan and Lake Erie can drop snow faster than plows keep up, and then tire compound matters more than anything else on the vehicle. Starting from the factory P245/75R17 size, a true winter tire on 17-inch wheels grips packed snow far better than an all-season and leaves sidewall for the potholes the next thaw brings.

Oil for a frozen-driveway start

The fluids table calls for SAE 5W-30 (2.0L), SAE 0W-20 (3.6L) and SAE 5W-40 (3.0L diesel) at 5 qt (2.0L), 5 qt (3.6L) and 9 qt (3.0L diesel), with synthetic oil in the specification. Synthetic stock copes with both ends of this region's weather, from a subzero start in the Upper Peninsula to a loaded summer climb in the Smokies. Match the exact specification on the filler cap, not just the viscosity.

Starting in single digits

Battery care in this schedule: inspect it and clean and tighten the terminals as required at each oil change, and the spec sheet rates it at 700 cold-cranking amps. A battery that bakes through a Nashville or Memphis summer ages faster, then gets found out by the first hard freeze. Have it load-tested in fall rather than waiting for a slow crank.

Which wheels do the pulling

Every 2021 version in the factory data drives with four-wheel drive. That is a real asset on a lake-effect morning in South Bend or Muskegon and on gravel switchbacks in West Virginia, but it does not shorten stopping distances: winter tires and extra following room still decide how a squall ends. On a used Wrangler, check that the system engages and the tires match in size and wear.

Snow plowing is a listed condition

Snow plowing is named in this schedule as one of the uses that calls for earlier fluid service. Keeping a long driveway or a cottage lane open through a west Michigan winter is precisely the kind of work that line describes, so log plowing hours alongside towing.

Antifreeze for both ends of the year

The system holds 10.3 qt (2.0L), 11.2 qt (3.6L) and 12 qt (3.0L diesel) of OAT coolant (10-year/150,000-mile formula). Stellantis manuals call for a 50/50 mix, good to about -34°F (-37°C), which is colder than a typical Great Lakes winter night; the real risk is dilution from top-ups with plain water. The same mix raises the boiling point for a loaded summer climb through the Tennessee mountains. A cheap tester checks the strength each fall.

Diesel through a Great Lakes winter

The diesel's biodiesel limit is up to B5. Diesel exhaust fluid freezes at about 12°F, and the truck's DEF system is built with heaters to thaw it after a cold start; never add anything to the fluid to stop it freezing. Tank capacity: 5.1 gal. Keep spare jugs somewhere that doesn't swing between hard freezes and summer heat.

Tank size for hill country

The 2021 Jeep Wrangler holds 17.5 to 21.5 gallons of fuel. Once you leave the interstate in West Virginia or eastern Kentucky, mountain routes can run a long way between stations, and the climbs burn more fuel than flat miles do. Fill up before heading into the hills.

Data behind these notes: owner's manual capacities, the Mopar service schedule and factory spec sheets. Regional advice is general, written for drivers from Michigan to Indiana.
