DYNAMOMETERA6E2014000042174WD testing/servicing
•Brake tester
Caution
•
To ensure the stability of the drag force of the viscous coupling always perform a brake test after
using the dynamometer or speed meter tester.
Note
•If there is a great amount of brake drag, it is probably due to the viscosity of the viscous coupling or the
center differential (RBC). To remove the influence of the coupling, jack up all four wheels of the vehicle
and verify that each wheel can be rotated freely by hand.
•Chassis dynamometer/speed meter tester
Caution
•
The vehicle may sway or surge forward when on the dynamometer. To prevent possible vehicle
movement, firmly secure it in place using steel retainers (chain, wire or similar) attached to the
front and rear towing hooks or to the tie down hooks.
•
Do not pop the clutch.
•
Do not accelerate suddenly.
Note
•The dynamometer/speed meter tester has two setting modes: propeller shaft removed mode and free
roller mode. After placing the vehicle on the tester and setting the wheels on the free rollers, start the
engine. For MTX vehicles, set the shift lever into second gear and gently, at low idle speed, release the
clutch pedal. For ATX vehicles, set the selector lever to D range, and slowly accelerate.

SCHEDULED MAINTENANCE
•To ensure efficient operation of the engine and all systems related to emission control, the ignition and fuel systems must
be serviced regularly. It is strongly recommended that all servicing related to these systems be done by an authorized
Mazda Dealer.
•After the described period, continue to follow the described maintenance at the recommended intervals.
•Refer below for a description of items marked* in the maintenance chart.
*1: If the vehicle is operated under any of the following conditions, change the engine oil and oil filter every 10,000 km
(6,250 miles) or shorter.
a. Driving in dusty conditions.
b. Extended periods of idling or low speed operation.
c. Driving for long period in cold temperatures or driving regularly at short distance only.
*2: Also inspect and adjust the power steering and air conditioner drive belts, if installed.
*3: If the brakes are used extensively (for example, continuous hard driving or mountain driving) or if the vehicle is
operated in extremely humid climates, change the brake fluid annually.
*4: If the vehicle is operated in very dusty or sandy areas, clean and if necessary, replace the air cleaner element more
often than the recommended intervals.
*5: Replacement of the timing belt is required at every 100,000 km (62,500 miles).
Failure to replace the timing belt may result in damage to the engine.
*6: Replacement of the timing belt is required at every 120,000 km (75,000 miles).
Failure to replace the timing belt may result in damage to the engine.
*7: If the vehicle is operated under any of the following conditions, change the rear differential oil
every 40,000 km (25,000 miles).
a. Towing a trailer or using a car - top carrier
b. Driving in dusty, sandy or wet condition
c. Extended periods of idling or low speed operation
d. Repeated short trips of less than 16 km (10 miles)
*8: If this component has been submerged in water, the oil should be changed.

Range determination
•Each range is determined by operating the selector lever, and switching ON/OFF the switch in the TR switch
internal circuit. The present range is detected according to the ON/OFF signal of the switch.
•The following switches are built into the TR switch, and determine each range when the switch is on.

MANUAL MODE SHIFT CONTROL DESCRIPTIONA6E571418901204Outline
Features
•The manual mode shift control is activated by moving the selector lever from the D to M range position (selector
lever is shifted over toward front passenger side).
•Manual mode shift control with a manual shifting system allowing selection of gear positions by manual
operation of the selector lever forward (-) and back (+) has been adopted. Moreover, engine braking for all
gears in manual mode according to the gear ratio is available.
— Shifting between 1GR and 2GR when the vehicle is stopped is possible.
— When shifting from the D to M range while driving, the same gear position is maintained.
— Consecutive shifting in the M range has been adopted. When shifting down from M range 4GR or 3GR, one
gear can be skipped over by rapidly tapping the selector lever two times in the down-shift (-) direction.
•Selector lever position and gear position indicator lights, built into the instrument cluster, have been adopted.
— The selector indicator light includes a selector lever position indicator that displays selector lever positions
and, a gear position indicator light that displays gear positions.
