316 Vehicle Care
Whether the vehicle is ready to be towed.
Just as preparing the vehicle for a long
trip, make sure the vehicle is prepared to
be towed.
Caution
Use of a shield mounted in front of the
vehicle grille could restrict airflow and
cause damage to the transmission. The
repairs would not be covered by the
vehicle warranty. If using a shield, only
use one that attaches to the towing
vehicle.
Dinghy Towing
For vehicles being dinghy towed, the vehicle
should be run at the beginning of each day
and at each RV fuel stop for about
five minutes. This will ensure proper
lubrication of transmission components.
To tow the vehicle from the front with all
four wheels on the ground:
1. Position the vehicle to be towed and
secure it to the towing vehicle.
2. Put the vehicle in N (Neutral).
3. Shut the engine off (vehicle will remain
in accessory mode).
4. Disconnect the negative ( ) terminal
connector from the 12-volt battery.
5. Close the hood of the vehicle.
Caution
If the vehicle is towed without
performing each of the steps listed under
Dinghy Towing, the automatic
transmission could be damaged. Be sure
to follow all steps of the dinghy towing
procedure prior to and after towing the
vehicle.
Caution
If 105 km/h (65 mph) is exceeded while
towing the vehicle, it could be damaged.
Never exceed 105 km/h (65 mph) while
towing the vehicle.
Once the destination is reached:
1. Shift the vehicle to P (Park).
2. Reconnect the negative ( ) terminal
connector to the 12-volt battery.
3. Start the engine and let it idle for more
than three minutes before driving the
vehicle.
Caution
Too much or too little fluid can damage
the transmission. Be sure that the
transmission fluid is at the proper level
before towing with all four wheels on the
ground.
Caution
Do not tow a vehicle with the front drive
wheels on the ground if one of the front
tires is a compact spare tire. Towing with
two different tire sizes on the front of
the vehicle can cause severe damage to
the transmission.
