0B-12 GENERAL INFORMATIONOWNER INSPECTIONS AND SERVICES
WHILE OPERATING THE VEHICLE Horn Operation Blow the horn occasionally to make sure it works. Check all the button locations. Brake System Operation Be alert for abnormal sounds, increased brake pedal travel or repeated puling to one side when braking. Also, if the brake warning light goes on, or flashes, something may be wrong with part of the brake system. Exhaust System Operation Be alert to any changes in the sound of the system or the smell of the fumes. These are signs that the system may be leaking or overheating. Have the system
inspected and repaired immediately. Tires, Wheels and Alignment Operation Be alert to any vibration of the steering wheel or the seats at normal highway speeds. This may mean a wheelneeds to be balanced. Also, a pull right or left on a straight, level road may show the need for a tire pressure adjustment or a wheel alignment. Steering System Operation Be alert to changes in the steering action. An inspection is needed when the steering wheel is hard to turn or
has too much free play, or is unusual sounds are noticedwhen turning or parking. Headlight Aim
Take note of the light pattern occasionally. Adjust the headlights if the beams seem improperly aimed.
AT EACH FUEL FILL A fluid loss in any (except windshield washer) system may indicate a problem. Have the system inspected and
repaired immediately. Engine Oil Level
Check the oil level and add oil if necessary. The best time to check the engine oil level is when the oil is warm.
1. After stopping the engine, wait a few minutes for the oil to drain back to the oil pan.
2. Pull out the oil level indicator (dip stick).
3. Wipe it clean, and push the oil level indicator back down all the way.
4. Pull out the oil level indicator and look at the oil level on it. 5. Add oil, if needed, to keep the oil level above the
lower mark. Avoid overfilling the engine, since this may cause engine damage.
6. Push the indicator all the way back down into the engine after taking the reading.
If you check the oil level when the oil is cold, do not runthe engine first. The cold oil will not drain back to the pan fast enough to give a true oil level reading. Engine Coolant Level and Condition Check the coolant level in the coolant reservoir tank
and add coolant if necessary. Inspect the coolant. Replace dirty or rusty coolant.
Windshield Washer Fluid Level
Check the washer fluid level in the reservoir. Add fluid if
necessary.
AT LEAST TWICE A MONTH Tire And Wheel Inspection and Pressure Check Check the tire for abnormal wear or damage. Also check for damaged wheels. Check the tire pressure when the tires are cold ( check the spare also, unless it is astowaway). Maintain the recommended pressures. Refer
to “Tire and Wheel” is in section 0B.
AT LEAST MONTHLY Light Operation Check the operation of the license plate light, the headlights (including the high beams), the parking lights,the fog lights, the taillight, the brake lights, the turn
signals, the backup lights and the hazard warning flasher. Fluid Leak Check Periodically inspect the surface beneath the vehicle for
water, oil, fuel or other fluids, after the vehicle has been
parked for a while. Water dripping from the air conditioning system after use is normal. If you notice fuel leaks or fumes, find the cause and correct it at once.
AT LEAST TWICE A YEAR Power Steering System Reservoir Level Check the power steering fluid level. Keep the power steering fluid at the proper level. Refer to Section 6A,
Power Steering System. Brake Master Cylinder Reservoir Level Check the fluid and keep it at the proper level. A low fluid level can indicate worn disc brake pads which mayneed to be serviced. Check the breather hole in the reservoir cover to be free from dirt and check for an open passage.

Temperature Model:ABD operation is a high thermal load for the brakes.
To avoid any damages at the brakes, the disk temperature is calculated with a mathematical model for each driven
wheel separately. After ignition on, the calculation starts with 30 °C and then three different phases are evaluated
separately and added: ABD operation, braking and coling phase.If the temperature is highter than 500 °C, ABD is disabled for this wheel.
It is permitted again, if the model has calculated down the 350 °C.
Lamp Concepts: The system is equipped with an ABD information lamp, which is blinking during ABD operation.The activation of the EBD, ABS warning lamp and the ABD info lampo is summarized in the following table:

REBUILD WARNINGS
Prior to rebuilding a transmission system, the following warnings are to be noted. Ensure that, before replacing a transmission the cooler
lines are flushed out to remove any debris. This can be
done by applying compressed air to the rear cooler line
forcing oil and any contaminants out of the front cooler line.
The cooler flow should be checked after the transmission
has been fitted. With the front cooler line connected
and the rear line run into a suitable container, measure
the flow over 15 seconds with the vehicle idling in park.
The flow rate should exceed 1 liter in 15 seconds.
Be wary of any situation where water enters the
transmission. This may result in fluid foaming and leaking
through the breather.
Ensure that both earth straps (one at the batted terminal
and one on the vehicle body) are connected in the
vehicle before connecting the positive side of the
battery.
Follow the throttle position calibration procedure in
section 7 of this manual if the powertrain control module
transmission control unit (PCM/TCU) is swapped.
DISASSEMBLY PROCEDURE
