Checking the Fluid Level
Prepare the vehicle as follows:
1. Park the vehicle on a levelplace. 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. When M is reached,
move the selector from M1
through M3. Then, position the
shift lever in P (Park).
4. Let the engine run at idle for two minutes or more.
Then, without shutting off the
engine:The transmission dipstick is located
near the center of the engine
compartment and will be labeled
with the graphic shown.
See Engine Compartment Overview
on page 10‑6 for more information
on location.
1. Flip the handle up and then 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 and then pull it
back out again.
A. COLD Range
B. WARM Range
C. HOT Range 3. Check both sides of the dipstick,
and read the lower level. The
fluid level must be in the
COLD (A) range for a cold
check, transmission temperature
27°C to 32°C (80°F to 90°F),
between the COLD (A) and
HOT (C) range for a WARM (B)
check, 50°C to 60°C (122°F to
140°F) or in the HOT (C)
cross-hatched range for a hot
check, 71°C to 93°C (160°F to
200°F). 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.

How to Add Automatic
Transmission Fluid
Refer toRecommended Fluids and
Lubricants on page 11‑12 to
determine what kind of transmission
fluid to use.
A. WARM Range
B. HOT Range
Using a funnel, add fluid down the
transmission dipstick tube only after
checking the transmission fluid
while it is warm or hot. A cold check
is used only as a reference. If the
fluid level is low, add only enough of
the proper fluid to bring the level up
to the middle of the WARM (A) or
HOT (B) range depending on the
ambient temperature and prior
driving conditions. Refer to
“How to Check Automatic
Transmission Fluid”, earlier in this
section for instructions on driving to
achieve warm or hot transmission
fluid. It does not take much fluid,
generally less than 0.5 L (1 pt).
Do not overfill.
Notice: Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑12.
.After adding fluid, recheck the
fluid level as described under
“How to Check Automatic
Transmission Fluid,” earlier in
this section.
.When the correct fluid level is
obtained, push the dipstick back
in all the way; then flip the
handle down to lock the
dipstick in place.
Engine Air Cleaner/Filter
The engine air cleaner/filter is
located near the center of the
engine compartment. See Engine

WARNING (Continued)
the surge tank pressure
cap—even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the surge tank
pressure cap, is hot. Wait for the
cooling system and surge tank
pressure cap to cool if you ever
have to turn the pressure cap.
If coolant is needed, add the proper
mixture directly to the radiator, but
be sure the cooling system is cool
before this is done.
1. Remove the radiator pressure cap when the cooling system,
including the radiator pressure
cap and upper radiator hose, is no longer hot. Turn the pressure
cap slowly counterclockwise
until it first stops. Do not press
down while turning the
pressure cap.
If a hiss is heard, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure cap, but now push down as you turn
it. Remove the pressure cap.3. Fill the radiator with the properDEX-COOL coolant mixture, up
to the base of the filler neck. See
Recommended Fluids and
Lubricants on page 11‑12 for
more information about the
proper coolant mixture.
4. Fill the coolant recovery tank to the COLD FILL mark.
5. Reinstall the cap back on the coolant recovery tank, but leave
the radiator pressure cap off.
