This is normal operation of the
automatic transmission.
Downhill Grade Assist
When traveling down steep grades
your transmission may automatically
downshift into a lower gear when the
brake is applied. You may feel this
downshift. This performance feature
of your automatic transmission
assists with engine braking to reduce
wear on your brake system. This is
normal operation of the automatic

Automatic Transmission
Fluid
It is not necessary to check
the transmission uid level.
A transmission uid leak is the only
reason for uid loss. If a leak
occurs, take your vehicle to the
dealer/retailer service department
and have it repaired as soon
as possible.
Change the uid and lter at the
intervals listed in the Maintenance
Schedule. See “Additional
Required Services” in Service
and Maintenance. Be sure to use
the transmission uid listed in
“Recommended Fluids and
Lubricants” in Service and
Maintenance.
Notice:Use of the incorrect
automatic transmission uid
may damage your vehicle,
and the damages may not becovered by your warranty.
See “Recommended Fluids
and Lubricants” in the Limited
Warranty, Maintenance and Owner
Assistance Information manual.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission uid level.
A transmission uid leak is the only
reason for uid loss. If a leak
occurs, take the vehicle to the
dealer/retailer service department
and have it repaired as soon
as possible. You may also have
your uid level checked by
your dealer/retailer when you have
your oil changed. See “Part D:
Recommended Fluids and
Lubricants” in Service and
Maintenance for the proper uid
to use.
Hydraulic Clutch
The hydraulic clutch linkage in
your vehicle is self-adjusting.
This system does not have its own
reservoir. It receives uid from
the brake master cylinder reservoir.
SeeBrakes on page 9-22for more
information.
Engine Coolant
The cooling system in your vehicle
is lled with DEX-COOL®engine
coolant. This coolant is designed to
remain in your vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst, if you add
only DEX-COOL
®extended life
coolant.
The following explains your cooling
system and how to add coolant
when it is low. If you have a problem
with engine overheating, see
Engine Overheating on page 9-15.
9-12 Vehicle Service and Care
ProCarManuals.com

Brakes
Brake Fluid
The brake master cylinder and, on
manual transmission vehicles,
the clutch hydraulic system use the
same reservoir. The reservoir is
lled with DOT-4 brake uid.
SeeEngine Compartment Overview
on page 9-6for the location of
the reservoir.
There are only two reasons why the
brake uid level in the reservoir
might go down. The rst is that the
brake uid goes down to an
acceptable level during normal
brake lining wear. When new linings
are put in, the uid level goes
back up. The other reason is that
uid is leaking out of the brake
or clutch hydraulic system. If it is,have the brake or clutch hydraulic
system xed, since a leak means
that sooner or later the brakes
or clutch will not work well.
It is not a good idea to top off the
brake uid. Adding brake uid
will not correct a leak. If uid is
added when the linings are worn,
there will be too much uid
when new brake linings are
installed. Add or remove brake uid,
as necessary, only when work is
done on the brake or clutch
hydraulic system.
{CAUTION
If your vehicle has too much
brake uid, it can spill on the
engine. The uid will burn if the
engine is hot enough. You or
others could be burned, and
your vehicle could be damaged.
Add brake uid only when work
is done on the brake and/or
clutch hydraulic system.Refer to “Scheduled Maintenance”
in the Limited Warranty,
Maintenance and Owner Assistance
Information manual to determine
when to check the brake uid.
Checking Brake Fluid
The brake uid can be checked
without taking off the cap by looking
at the brake uid reservoir.
The uid level should be above
MIN. If it is not, have your brake
hydraulic system checked to see
if there is a leak. After work is done
on the brake hydraulic system,
make sure the level is above the
MIN but not over the MAX mark.
What to Add
When you do need brake uid,
use only DOT-4 brake uid.
It is recommended that you ush
the brake hydraulic system and
rell it with new DOT-4 uid
at a regular maintenance service
every two years. See “Additional
