WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground and the rear wheels off the ground using a wheel lift
On 4x4 vehicles, it is recommended that your vehicle be towed using
flatbed equipment with all the wheels off the ground. However, a wheel
lift may be used to lift the rear of the vehicle so long as, depending on
vehicle configurations, the following preparations are met:
• On Electronic Shift-On-the-Fly (ESOF) vehicles, the 4WD control is
turned to the 2WD position prior to towing.
• On manual-shift transfer case vehicles, the front wheel hub locks are
in the UNLOCKED position prior to towing.
Note: Towing an ESOF 4WD vehicle with the front wheels on the ground
without disengaging the front hubs may cause damage to the automatic
transmission.
