Please refer to the techni cal specification sheet for the rated total mass value and shaft loading capacity.

2. BEFORE DRIVING YOUR JAC

BREAKING IN YOUR VEHICLE

Operate the vehicle at moderate speeds during the first 1,000 km (600 miles) to break it in. Make certain that the follow ing points in particular are strictly observed.

Allow the engine to warm up fully until the coolant temperature reaches about 60 (140 ).

Avoid racing the engine, abrupt start, acceleration and braking.

Avoid overloading the vehicle, as this will result in a shorter life.

Avoid high speed operation as far as possible. During break-in operation, make sure that the engine speed does not exceed 1,500 rpm.

Make sure that your vehicle does not miss the first 1,000 km(600 miles) and 5,000 km (2,500 miles ) inspections.

After the first 1,000 km (600 miles) and 5,000 km(2,500 miles) or driving, take your vehicle to your nearest service shop for inspections based on the 'Maintenance Requirements'.

SEAT BELTS (3-Point Type)

To Fasten Your Belt

To fasten your seat belt, pull it out of the retractor and insert the metal tab into the buckle. There will be an audible "click,, when the tab locks into the buckle. The seat belt automatically adjusts to the proper length only after the lap belt is adjusted manually so that it fits snugly around your hips. If you lean forward in a slow, easy motion, the belt will extend and let you move around. If there is a sudden stop or impact, however, the belt will lock into position. It will also lock if you try to lean forward too quickly.

Check to make sure the belt is properly locked and that the belt is not twisted.

NOTE:

If the driver's seat belt is not fastened when the ignition key Is in the "ON" posi tion, the seat belt warning light will flash.

Adjusting Your Seat Belt

You should place the belt as low as possible on your hips, not on your waist. If located too high on your body, the chances of sliding out from under it and suffering serious injury or death are increased. Both arms should not be under or over the belt. Rather, one should be over and the other under, as shown in the illustration.

To Release the Seat Belt

The seat belt is released by pressing the release button in the locking buckle. When it is released, the belt should automatically draw back into the retractor. If this does not happen, check the belt to be sure it is not twisted, then try it a gain.

TACHOMETER

The tachometer registers the speed of your engine in revolutions per minute (rpm). It is useful to help you shift at the appropriate engine speed to avoid lugging or over running.

CAUTION:

The engine should not be raced to such a speed that the needle enters the red zone on the tachometer face. This can cause severe engine damage.

SPEEDOMETER

The speedometer indicates the vehicle speed in kilometers or miles per hour.

ODOMETER

The odometer records the total driving distance in kilometers or miles, and is useful for keeping a record for maintenance intervals.

The position of the pointer will vary slightly when accelerating, braking, or when the vehicle is going up or down hill. So check your fuel supply when the vehicle is more or less specified level, whether standing still or moving.

WATER TEMPERATURE GAUGE

When the ignition switch is "ON", this gauge indicates the temperature of the coolant. Under most driving conditions, the needle will remain at approximately the halfway point. Stop and go driving, driving at high speeds during warm weather or driving up a steep gradient may cause the pointer to move toward the red sector. If your vehicle overheats, water lamp comes and the indicator goes up. However when the quantity of coolant is below of the specification, the warning buzzer will sound.

At this time, stop your vehicle immediately.

VOLTAGE GAUGE

The voltmeter indicates the battery state of charge. Check while the engine is running. The pointer should always indicate between 20 and 30 volts.

If the pointer reads above 30 volts or below 20 volts, contact your nearest au thorized JAC dealer.
