TEMPERATURE CONDITIONS FOR CHECKING The fluid level should be checked using the HOT range (L & H marks) on the dipstick at fluid temperatures between 122 and 176°F (50 and 80°C) after the vehicle has been driven approximately 5 minutes in urban areas after the engine is warmed up. The level can be checked at fluid temperatures between 86 and 122°F (30 and 50°C) using the COLD range on the dipstick for reference, after the engine is warmed up but before driving. However, the fluid level must be rechecked 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 selector lever through each gear range, ending in P. 3. Check the fluid level with the engine idling. 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 fluid level cannot be read accurately. You should wait until the fluid has cooled down (about 30 minutes). 4. Remove the dipstick and wipe it clean with lint-free paper. 5. Re-insert the dipstick into the charging pipe as far as it will go. 6. Remove the dipstick and note the reading. If the level is on the low side of either range, add fluid to the charging pipe. ¼ Do not overfill. ¼ 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 a NISSAN dealer for more information regarding suitable fluids, including recommended brand(s) of DexronTM III/ MerconTM or DexronTM IIE/MerconTM Automatic Transmission Fluid.
