Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak occurs,
take the vehicle to your dealer and
have it repaired as soon as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact your dealer
for additional information.
Caution
Use of the incorrect automatic
transmission fluid may damage the
vehicle, and the damage may not be
covered by the vehicle warranty.
Always use the correct automatic
transmission fluid. See
Recommended Fluids and Lubricants
0
420.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule 0410, and be sure to use the
fluid listed in Recommended Fluids and
Lubricants 0420.
Manual Transmission Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak occurs,
take the vehicle to your dealer and
have it repaired as soon as possible.
See Recommended Fluids and
Lubricants 0420 for the proper fluid
to use.

Hydraulic Clutch
For vehicles with a manual
transmission, it is not necessary to
regularly check brake/clutch fluid
unless there is a leak suspected.
Adding fluid will not correct a leak.
A fluid loss in this system could
indicate a problem. Have the system
inspected and repaired.
When to Check and What to Use
The brake/hydraulic clutch fluid
reservoir cap has this symbol on it.
SeeEngine Compartment Overview
0 331 for reservoir location. The
common hydraulic clutch and brake
master cylinder fluid reservoir is filled
with brake fluid as indicated on the
reservoir cap. See Brake Fluid0352 for
brake fluid to use.
How to Check and Add Fluid
Visually check the brake/clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
side of the reservoir. The brake/
hydraulic clutch fluid system should
be closed and sealed.
Do not remove the cap to check the
fluid level or to top-off the fluid level.
Remove the cap only when necessary
to add the proper fluid until the level
reaches the MIN line.
Engine Air Filter Life
System
If equipped, this feature provides the
engine air filter’s remaining life and
best timing for a change. The timing
to change an engine air filter depends
on driving and environmental
conditions.
When to Change the Engine Air
Filter
When the Driver Information Center
(DIC) displays a message to replace
the engine air filter at the next oil
change, follow this timing. When the DIC displays a message to
replace the engine air filter soon,
replace the engine air filter at the
earliest convenience.
The system must be reset after the
engine air filter is changed.
If the DIC displays a message to check
the engine air filter system, see your
dealer.
How to Reset the Engine Air
Filter Life System
To reset:
1. Place the vehicle in P (Park).
2. Display the Air Filter Life on the DIC. See Driver Information Center
(DIC) (Base Level) 0116 or
Driver Information Center (DIC)
(Uplevel) 0119.
3. Press
Ton the steering wheel,
or press the trip odometer reset
stem if the vehicle does not have
DIC controls, to move to the Reset/
Disable display area. Select Reset,
then press the thumbwheel or
press the reset stem for several
seconds.

SOON message displays, have the
engine oil and filter changed within
the next 1 000 km (600 mi). If driven
under the best conditions, the engine
oil life system may not indicate the
