This taken from my 2005 Honda Pilot Owner’s Manual:
Towing Your Vehicle Behind a Motorhome
Your vehicle can be towed behind a motorhome at legal highway speeds up to 65 mph (100 km/hr). Do not exceed 65 mph ((100 km/hr) or severe transmission damage will occur. To avoid damage to the 4WD system, it must be towed with all four wheels on the ground (flat towing).
When purchasing a tow bar, make sure you select a reputable manufacturer. Follow the manufacturer’s attachment instructions carefully.
Perform the following procedure everyday immediately before you begin towing. Otherwise severe automatic transmission damage will occur.
- Check the transmission fluid level. Do not overfill!
- Start the engine.
- Press on the brake pedal. Move the shift lever through all its positions.
- Shift to D, then to N. Let the engine sun for three minutes, then turn it off.
- Release the parking brake.
- Leave the ignition switch in the ACCESSORY (I) position so the steering wheel does not lock. Make sure the radio and any items plugged into the accessory power sockets are turned off so you do not run down the battery.
If you tow more than 8 hours in one day, you should repeat the above procedure at least every 8 hours (when you stop for fuel, etc.)
Improper towing preparation will damage the transmission. Follow the above procedure exactly. If you cannot shift the transmission or start the engine, your car must be transported on a flat-bed or trailer.
I have followed the above instructions faithfully for over 60,000 km of towing with one exception.
The instructions state to move the shift lever through all positions. I had heard somewhere that it was wise to avoid reverse, so I have. In fact, any time I inadvertently shifted into reverse, I always begin the procedure all over again.
The instructions do not state to let the engine idle with the shift lever in the D position, so I have never done that.
I NEVER exceed the allowable towable limit of 8 hours. In fact, I did not install a battery charger for that very reason. I usually start the toad to charge the battery and put the transmission through the paces every 4 to 6 hours.
I have exceeded the allowable towable speed limit, sometimes running as high as 70 MPH when conditions seem to allow.
I have had the oil changed in the transmission and trans-axle three times to date, and the used oil has always drained out nice and clean.
Our 2005 Honda Pilot now has about 265,000 km and still runs as new.
Honda states that 65 MPH is 100 KM. It is not. It is 104 KM.
