VEHICLE CARE 335
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
0417.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule 0408, and be sure to use the
fluid listed in Recommended Fluids and
Lubricants 0417.
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 0417 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
0 326 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 Fluid0348 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.
