Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
Aerodynamic Speed Penalty
EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.

Recall Intelligence
THERE IS INSUFFICIENT CLEARANCE BETWEEN THE RIGHT FRONT BRAKE CALIPER HYDRAULIC LINE AND THE ENGINE OIL COOLER LINE. IF THE LINES COME IN CONTACT WITH EACH OTHER, THE CHAFING MAY DAMAGE THE BRAKE LINE AND CAUSE A FLUID LEAK.
Consequence & Remedy
Consequence: HYDRAULIC FLUID LEAK COULD RESULT IN A LOSS OF BRAKES WITH THE POTENTIAL FOR AN ACCIDENT.
Remedy: ADD A PROTECTIVE SHIELD TO PREVENT CONTACT AND REPLACE ANY DAMAGED HYDRAULIC PIPE.
THE FUSE IN THE REAR WINDOW DEFROSTER CIRCUIT MAY BLOW DUE TO THE AMPERAGE LOAD EXCEEDING FUSE CAPACITY.
Consequence & Remedy
Consequence: REAR STOP LAMPS, EXCEPT THE HIGH MOUNTED STOP LAMP, WOULD FAIL. THERE MAY NOT BE SUFFICIENT STOP SIGNAL WARNING TO THE FOLLOWING TRAFFIC WHICH MAY CAUSE AN ACCIDENT.
Remedy: INSTALL AN ADDITIONAL FUSED CIRCUIT TO HANDLE THE MAIN STOP LAMPS.
