Tow haul function
Hi I am driving a 2013 F150 FX4 with a 5 litr engine. My question is I drove it once with the tow haul function ON when towing a dbl axle trailer. Going down hill every time you hit the brakes it downshift and after hitting the brake pedal 3 times the engine start over revving. Is there a way to avoid the downshift because when towing a heavy load I am afraid that the rear wheel will lock up on me.
Thank you
Thank you

Excerpted from the 2013 F-150 owner's manual (page 204+) ...
D (Drive) with Tow/Haul On
The Tow/Haul feature improves transmission operation when towing a trailer or a heavy load. All transmission gear ranges are available when using Tow/Haul.
Tow/Haul can be activated by pressing the transmission control switch on the end of the gearshift lever (column-shift transmission) or on the side of the gearshift lever (floor-shift transmission).
The TOW HAUL indicator light will illuminate in the instrument cluster.
Tow/haul delays upshifts to reduce frequency of transmission shifting. Tow/haul also provides engine braking in all forward gears when the transmission is in the D (Drive) position; this engine braking will slow the vehicle and assist the driver in controlling the vehicle when descending a grade. Depending on driving conditions and load conditions, the transmission may downshift, slow the vehicle and control the vehicle speed when descending a hill, without the accelerator pedal being pressed. The amount of downshift braking provided will vary based upon the amount the brake pedal is pressed.
To deactivate the tow/haul feature and return to normal driving mode, press the button on the end of the gearshift lever. The TOW HAUL light will no longer be illuminated. Tow/haul will also deactivate when the vehicle is powered down.
Don't have one ?
