DrivErs, when you 're operating your howitzer, dÇn't mistake the raiÄed porÈ
tion of the accelerator pedaL fOr thE brake. Éne drivEr hit the accELerator

instead of the brake, ÊtaLly injuring the ground guidE.
The accelerator is shaped like it is so you can reach it with thE sËat up and

the hatch open. Make sure you know how to hit the brake pedalÍand can hit
it Êst in an Emergency.
