Tires, Wheels and Loading
Vehicles with an automatic transmission and push button start
system:
1. Release the parking brake.
2. Activate the ignition by pressing the START/STOP button, but not
applying the brake pedal.
3. Press the brake pedal, then move the gearshift to the N (Neutral)
position. There must be battery power to properly move the
transmission's internal components to N (Neutral). Also, moving the
gearshift to the N (Neutral) without first having the ignition on limits the
towing capability to 35 mph (56 km/h) and 50 miles (80 km).
4. Deactivate the ignition by pressing the START/STOP button, but not
applying the brake pedal.
5. Disconnect the negative (black) cable from the battery. (The door key
[inside the Intelligent Access Key] is needed to lock/unlock doors when
the battery cable is disconnected. Also, the anti-theft system is disabled
until the battery cable is reconnected.) Refer to Battery in the
Maintenance and Specifications chapter when disconnecting and
reconnecting the battery cable.
6. The maximum towing speed is 70 mph (113 km/h).
7. There is no limitation on towing distance.
8. When done towing, start the engine within 15 minutes of reconnecting
the battery cable. When reconnecting that cable, tighten it until it's snug
against the terminal; be careful not to overtighten.
Note: The vehicle must be towed in the forward position to ensure no
damage is done to the internal transmission components. In addition, it is
recommended that you follow the instructions provided by the
aftermarket manufacturer of the towing equipment, if provided.
