1-3 GENERAL INFORMATION
• Chassis Dynamometer Test
The propeller shaft must be removed and the vehicle made
into front wheel drive. To undo the propeller shaft, do not
disconnect the front propeller shaft ASSY. Only disconnect
the rear propeller shaft ASSY and lock the center differential.
When reconnecting the front and rear propeller shaft ASSV's,
align the matching marks very carefully.
• Tire Balance Test (On-car-machine)
For safety when doing the tire balance testing, disconnect the
propeller shaft and keep the center differential locked. Also,
do not drive the tires with the engine, but use the on-car-
machine to rotate the tires and do the balance testing.
a. In doing the testing, be sure to jack up both the left and
right sides and put wheel blocks behind the tires contacting
the ground.
b. Make sure that the transmission is in neutral gear position .
• Towing
If the following conditions cannot be met, raise and support
all four wheels to move the vehicle.
a. Before towing, check transmission oil and differential oil
levels and top up to the specified level if necessary.
b. The ignition switch should be in the "ACC" position while
the vehicle is being towed.
1) Rope Towing
CD
Turn the differential lock switch to the "OFF"
position and make sure that the differential lock indicator
light ("DIFF LOCK") has gone off. (Confirmation of
differential lock cancellation.)
CV
When the vehicle has a large air spoiler skirt on it,
wrap the tow rope with a rag to prevent the rope from
scratching the air spoiler.
Tow the vehicle with the engine off .
• The power steering will not be operating so the steering
will be stiff .
• The brake booster will not be operating so the braking
will be very weak.

CD
Turn the differential lock switch to the "OF F"
position and make sure that the differential lock indicator
light ("DIFF LOCK") has gone off. (Confirmation of
differential lock cancellation.)
CV
The center differential will be rotating faster than
normal. Check the transmission oil which also serves as
the center differential oil and add if oil level is low.
Tow at less than 30 km/h (19 MPH) .
@
Do not tow for more than 50 km (31 miles).

• Differential Lock Cancelling Method
L1-41S
1) Under normal circumstances, start the engine, turn the
differential lock switch off and, with the tires pointed straight,
move the vehicle either forward or backward.
2) If the engine cannot be started, such as with a dead
battery or when the vacuum actuator is not working, raise the
front (or rear) wheels and move the differential lock lever, on
the right side of the transmission, towards the rear of the
vehicle.
