3. Check that the lubricant level
is up to the bottom of the ller
plug hole.
4. If the uid level is good, install
the plug and be sure it is fully
seated. If the uid level is low,
add more uid as described
in the next steps.
How to Add Fluid
Refer to the Maintenance Schedule
to determine what kind of uid to
use. SeeRecommended Fluids and
Lubricants on page 6-12.
1. Remove the ller plug.
2. Add uid at the ller plug hole.
Add only enough uid to bring
the uid level up to the bottom of
the ller plug hole.
3. Install the ller plug. Be sure the
plug is fully seated.
Hydraulic Clutch
The hydraulic clutch linkage in
the vehicle is self-adjusting.
The clutch master cylinder reservoir
is lled with hydraulic clutch uid.
The hydraulic clutch uid reservoir
cap has this symbol on it. See
Engine Compartment Overview on
page 5-10for reservoir location.
It is not necessary to regularly check
clutch uid unless a leak in the
system is suspected. Adding uid
will not correct a leak.
A uid loss in this system could
indicate a problem. Have the system
inspected and repaired.
When to Check and What
to Use
Refer to the Maintenance Schedule
to determine how often to check
the uid level in the clutch master
cylinder reservoir and for the proper
uid. SeeRecommended Fluids
and Lubricants on page 6-12.
How to Check and Add Fluid
The proper uid should be added
if the level does not reach the
bottom of the diaphragm when it is
in place in the reservoir. See the
instructions on the reservoir cap.
Service and Appearance Care 5-21

If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
Climbs a long hill on a hot day.
Stops after high-speed driving.
Idles for long periods in traffic.
Tows a trailer. See “Driving
on Grades” underTowing a
Trailer on page 4-42.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.3. In heavy traffic, let the engine idle
in N (Neutral) while stopped. If it
is safe to do so, pull off the road,
shift to P (Park) or N (Neutral) and
let the engine idle.
If the temperature overheat gage is
no longer in the overheat zone
or an overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle
slow for about 10 minutes. Keep a
safe vehicle distance from the
car in front of you. If the warning
does not come back on, continue to
drive normally.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until
it cools down.
Engine Fan Noise
This vehicle has a clutched engine
cooling fan. When the clutch is
engaged, the fan spins faster
to provide more air to cool the
engine. In most everyday driving
conditions, the clutch is not
engaged. This improves fuel
economy and reduces fan noise.
Under heavy vehicle loading,
trailer towing and/or high outside
temperatures, the fan speed
increases when the clutch engages.
So you may hear an increase in
fan noise. This is normal and should
not be mistaken as the transmission
slipping or making extra shifts.
It is merely the cooling system
functioning properly. The fan will
slow down when additional cooling
is not required and the clutch
disengages.
You may also hear this fan noise
when you start the engine. It will go
away as the fan clutch disengages.
