TOWING
Proper towing equipment is necessary to prevent
damage to the vehicle during any towing operation.
Laws and regulations applicable to vehicles in tow
must always be observed.
Whether the vehicle is equipped with either an auto-
matic or manual transaxle, release the parking brake,
place the selector lever (shift lever) in neutral, and set
the ignition key in the "ACC" position. As a rule,
towed vehicles should be pulled with their drive
wheels off the ground.
If excessive vehicle damage or other conditions pre-
vent towing a vehicle with its drive wheels up, use
wheel dollies. With all four wheels on the ground, the
vehicle may be towed only forward. In this case, it
cannot be towed at a speed exceeding 56 km/h (35
mph) for more than 80 km (50 miles) without danger
of damaging the transaxle.
If the towing speed will exceed 56 km/h (35 mph),
or if the towing distance will exceed 80 km (50 miles),
use either of these two methods:
1. Place the front wheels on dollies.
2. Tow with the front wheels off the ground.
CAUTIONS
a) The power assist for the brakes and steer-
ing (if so equipped) will be inoperable while
the engine is off.
b)When either of the towing hooks is used,
always pull the cable or chain straight away
from the hook and do not apply any side-
ways force to it. To further help prevent
damage, do not take up slack too quickly
in the cable or chain.
c) The rear towing hook should be used only
in an emergency situation, (e.g., to pull the
vehicle from a ditch, a snowbank, or mud).
