Brake
Foot brake
Check the following:
• that brake pedal has proper travel,
• that brake works properly,
• that it is free from noise,
• that vehicle does not pull to one side when brake is applied.
• and that brake do not drag.
Parking brake
Check that lever has proper travel.
WARNING!
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property
damage. Be prepared to apply regular brake
quickly even if vehicle should start to move.

Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and brake
lever is pulled all the way.
Steering
• Check to ensure that steering wheel is free from instability, or abnormally heavy feeling. • Check that the vehicle does not wander or pull to one
side.
Engine
• Check that engine responds readily at all speeds.
• Check that engine is free from abnormal noise and abnormal vibration.
Body, Wheels and Power Transmitting System
Check that body, wheels and power transmitting system
are free from abnormal noise and abnormal vibration or
any other abnormal condition.
Meters and Gauge
Check that speedometer, odometer, fuel meter,
temperature gauge, etc. are operating accurately.
Lights
Check that all lights operate properly.
Windshield Defroster
Periodically check that ai r comes out from defroster
outlet when operating heater or air conditioning.
Set mode control lever to defroster position and fan
switch lever to “HI” position for this check.

Description of Electric Throttle Body System CalibrationS7RS0B1101008
ECM calculates controlled opening of the throttle valve on the basis of the completely closed throttle valve position of
the electric throttle body system. The completely closed position data is saved in memory of ECM. However, the
completely closed position of the throttle valve of the electric throttle body system (signal voltage from throttle position
sensor when throttle is completely closed) differs one from the other depending on individual differences of the throttle
valve and throttle position sensor. As such individual diff erences must be taken into account for controlling the throttle
valve, it is necessary to register the completely closed throttle valve position data in ECM. When such data is
registered in ECM, it is sa ved in RAM (memory) of ECM and used as the base data for controlling the throttle valve.
This data is cleared, when any of the works described in “Preca utions of Electric Throttle Body System Calibration” is
performed.
Also, after replacement of the throttle body and/or APP sensor , the completely closed position data in memory of ECM
must be cleared once and a new one must be registered, or ECM cannot judge the complete closure position properly.
For the procedure to register such data, refer to “Electric Throttle Body System Calibration in Section 1C”. (After the
completely closed position data is cleared , ECM, for the first time only, opens and closes the throttle valve for about 5
seconds after the ignition switch is turned ON position, for re gistration of the completely closed throttle valve position.
If the engine is started during this registration process, such symptom as “longe r cranking” or “slow rise of revolution
speed immediately after start-up” may occur. However, turning OFF the ignition switch once and restarting will set
correct registration.)
