odometer readings (as required by Federal Law), but it will also resynchronize
transmission shift points for vehicles equipped with electronically controlled
transmissions.
Select CORRECT TIRE SIZE ONLY if you have only changed the tire size.
Select CORRECT GEAR RATIO ONLY if you have only changed the rear axle gear
ratio.
Select CORRECT BOTH TIRE & GEAR if you have changed both the tire size and rear
axle gear ratio.
Touch ENTER after making your selection.
