RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational (RV) towing.
An example of recreational towing would be towing your vehicle behind
a motor home.
Note: Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to the Climate
Controls chapter for more information.
In case of a roadside emergency with a disabled vehicle, see Wrecker
towing in the Roadside Emergencies chapter.
These guidelines are designed to ensure that your transmission is not
damaged after the vehicle is hooked-up to the RV or tow dolly.

RECOVERY HOOKS
WARNING: Using recovery hooks is dangerous and should only
be done by a person familiar with proper vehicle recovery safety
practices. Improper use of recovery hooks may cause hook failure
and/or separation from the vehicle and could result in serious injury or
death.
WARNING: Always slowly remove the slack from the recovery
strap prior to pulling. Failure to do so can introduce significantly
higher loads which can cause the recovery hooks to break off, or the
recovery strap to fail which can cause serious injury or death.
