10-12 Vehicle Care
Checking the Fluid Level
Prepare the vehicle as follows:
1. Park the vehicle on a level
place. Keep the engine running.
2. With the parking brake applied,
place the shift lever in P (Park).
3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, position the
shift lever in P (Park).
4. Let the engine run at idle for
three minutes or more.
Then, without shutting off the
engine, use the steps that follow.
The transmission dipstick is
near the center of the engine
compartment and will be labeled
with the graphic shown.
See Engine Compartment Overview
on page 10 6.
1. Flip the handle up, pull out the
dipstick, and wipe it with a clean
rag or paper towel.
2. Push it back in all the way, wait
three seconds, then pull it back
out again.
3. Check both sides of the dipstick,
and read the lower level. The
fluid level must be in the COLD
area for a cold check or in the
HOT or cross-hatched area for a
hot check. Be sure to keep the
dipstick pointed down to get an
accurate reading.
4. If the fluid level is in the
acceptable range, push the
dipstick back in all the way; then
flip the handle down to lock the
dipstick in place.
