So you're about to enter a parking garage that's marked 9' 6", and you're driving your new Sprinter 4x4. With a quick glance at our Height Warning sticker, you'll have peace of mind knowing you'll have 2" to spare.
We were cruising through Europe one summer in a VW LT Westfalia camper that was 3 meters high, looking down at the sticker helped us avoid catastrophe many times. This sticker is a small price to pay considering the damage you might incur.
We made this sticker small enough to fit next to the radio buttons, or place it on the inside of the sun visor. ( or both! ) We added metric dimensions in case you travel to Canada or other exotic lands.
