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 0 368.
Change the fluid and filter at the intervals
listed in Maintenance Schedule 0 363, and
be sure to use the fluid listed in
Recommended Fluids and Lubricants 0 368.

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 0 368
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. See Engine
Compartment Overview 0 288 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 Fluid 0 308 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

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.
