10-14 Vehicle Care
Wait at least 30 minutes before
checking the transmission fluid level
if the vehicle has been driven:
. When outside temperatures are
above 32°C (90°F).
. At high speed for quite a while.
. In heavy traffic — especially in
hot weather.
. While pulling a trailer.
To get the right reading, the fluid
should be at normal operating
temperature, which is 82°C to 93°C
(180°F to 200°F).
Get the vehicle warmed up by
driving about 24 km (15 mi) when
outside temperatures are above
10°C (50°F). If it is colder than 10°C
(50°F), drive the vehicle in 3 (Third)
until the engine temperature gauge
moves and then remains steady for
10 minutes.
A cold fluid check can be made
after the vehicle has been sitting for
eight hours or more with the engine
off, but this is used only as a
reference. Let the engine run at
idle for five minutes if outside
temperatures are 10°C (50°F) or
more. If it is colder than 10°C
(50°F), the engine may have to idle
longer. Should the fluid level be low
during this cold check, check the
fluid hot before adding fluid.
Checking the fluid hot gives a more
accurate reading of the fluid level.
Checking the Fluid Level
To prepare the vehicle:
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 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:
1. Flip the handle up and then pull
out the dipstick and wipe it with
a clean rag or paper towel.
The automatic transmission
dipstick handle with this symbol
on it is located in the engine
compartment on the passenger
side of the vehicle.
See Engine Compartment
Overview on page 10‑6 for more
information on location.
2. Push it back in all the way, wait
three seconds, and pull it back
out again.
