TOWING
Proper towing equipment is necessary to prevent damage to
the vehicle.
Laws and regulations applicable to vehicles in tow
must al-
ways be observed.
As a general rule, towed vehicles should be pulled with the
driving wheels off the ground. If excessive damage or other
conditions prevent towing the vehicle with the driving wheels
off the ground, use wheel dollies.
With either automatic or manual transaxle:
1, Set the ignition switch in the ACC position;
2. Place the selector lever or shift lever in N (Neutral);
3. Release the parking brake.
Caution
l 50 not tow the vehicle backward with driving wheels
on the ground. This may cause internal damage to
the transaxles.
l 50 not use the hook loops under the front and rear
of the vehicle for towing purposes These hook
loops are designed ONLY for transport tie-down. If
tie-down hook loops are used fur towing, the
front/rear bumper wiIl be damaged.
