But if it's near or below MIN, add
enough oil to bring the level to MAX.

positioned properly before reinserting
the dipstick.

qInspecting Automatic Transaxle
Fluid Level
The automatic transaxle fluid level should
be inspected regularly. Measure it as
described below.
The volume of fluid changes with the
temperature. Fluid must be checked at idle
without driving at normal operating
temperature.
CAUTION
lLow fluid level causes transaxle
slippage. Overfilling can cause
foaming, loss of fluid, and transaxle
malfunction.
lUse specified fluid (page 10-4). A
nonspecified fluid could result in
transaxle malfunction and failure.
1. Park on a level surface and set the
parking brake firmly.
2. Idle the engine about two minutes.
Push down on the brake pedal.
3. Move the shift lever through all ranges
