TEMPERATURE CONDITIONS FOR CHECKING ATF ● The fluid level should be checked using the HOT range on the dipstick after the following conditions have been met: - The engine should be warmed up to operating temperature. - The vehicle should be driven at least 5 minutes. - The automatic transmission fluid should be warmed to between 122° and 176°F (50° to 80°C). ● The fluid can be checked at fluid temperatures of 86° to 122°F (30 to 50°C) using the COLD range on the dipstick, after the engine is warmed up and before driving. However, the fluid should be re-checked using the HOT range. 1. Park the vehicle on a level surface and set the parking brake. 2. Start the engine and then move the shift selector lever through each gear range. Move the shift selector lever to P (Park) after you have moved it through all ranges. ADI1012 CAUTION DO NOT OVERFILL. USE ONLY NISSAN Matic 'D' (Continental U.S. and Alaska) or Genuine NISSAN Automatic Transmission Fluid (Canada). DexronTM III/MerconTM or equivalent may also be used. Outside the continental United States and Alaska contact an authorized NISSAN dealership for more information regarding suitable fluids, including recommended brand(s) of DexronTM III/MerconTM Automatic Transmission Fluid. NOTE: If the vehicle has been driven for a long time at high speeds, or in city traffic in hot weather, or if it is being used to pull a trailer, the accurate fluid level cannot be read. You should wait until the fluid has cooled down (about 30 minutes). 3. Check the fluid level with the engine idling. 4. Remove the dipstick and wipe it clean with lint-free paper. 5. Reinsert the dipstick into the charging pipe as far as it will go. 6. Remove the dipstick and note the reading. If the level is at the low side of either range, add fluid through the charging pipe. 8-10 Do-it-yourself
