Automatic transmission fluid

Checking the automatic transmission fluid level
The automatic transmission fluid level must be checked regularly.
Park the vehicle on a level surface with the parking brake applied, and check the level using the following procedure.
1. Place the shift lever in N and make sure the engine is running at normal idle speed.
2. Once the transmission is sufficiently warm (fluid temperature 70~80°C), for example after 10 minutes of normal driving, move the lever through all positions, then return it to N or P.

3. Make sure the fluid is at the "HOT" level on the dipstick. If the level is low, add fluid. If the level is high, drain fluid from the drain hole.
4. If the level is checked when the fluid is cold (temperature 20~30°C), add fluid up to the "COLD" level, then recheck it following step 2.
WARNING - Clutch fluid: The fluid level must be checked at normal engine operating temperature. This means the engine, radiator, radiator hose, exhaust system, etc. are very hot. Take great care not to burn yourself during this procedure. NOTICE: A low fluid level causes clutch slipping. A level that is too high causes foaming, fluid leakage and clutch malfunction. - Using a non-specified fluid causes clutch malfunction and failure. WARNING - Parking brake: To prevent sudden vehicle movement, apply the parking brake and depress the brake pedal before moving the shift lever.NOTE
The "COLD" level is for reference only and must NOT be used to determine the clutch fluid level.
NOTE
New clutch fluid must be red. Red dye is added in small amounts so that the assembly plant can identify it as automatic transmission fluid and distinguish it from engine oil or antifreeze.
The dye does not indicate the quality of the fluid and is not permanent.
As the vehicle is used, the fluid becomes darker. Eventually, the fluid takes on a light brown appearance. Therefore, it is recommended that the system be replaced by an authorized HYUNDAI dealer according to the maintenance schedule at the beginning of this section.
Use only the specified fluid (Refer to "Recommended Lubricants and Capacities" in Section 8.).
