Section 4
Wait at least 30 minutes before
checking the fluid level if you have
been driving:
• when outside temperatures are
above 32°C (90°F)
• at high speeds for an extended
time
• in heavy traffic (especially in
hot weather)
• while pulling a trailer
Cold Check Procedure
Perform a cold check only to deter-
mine whether the transmission has
enough fluid to be operated safely
until a hot check can be made.
The hot check procedure is the
most accurate method to check
the fluid level.
After a cold check, perform a hot
check at the first opportunity,
once the fluid reaches normal
operating temperature.
Check the fluid level at every
engine oil change:
1. Park the vehicle on a level sur-
face and apply the park brake.
2. With the shift lever in P (Park),
start the engine.
3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about 3 seconds in
each range. Then position the
shift lever in
P (Park).
4. Run the engine at idle speed
for about 3 to 5 minutes.
5. With the engine running at
idle speed, remove the dip-
stick, wipe it clean and reinsert
it by pushing it down all the
way.
