Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss. If a
leak occurs, take the vehicle to the dealership service
department and have it repaired as soon as possible. You
may also have your fluid level checked by your dealer or
service center when you have your oil changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
•
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•
In hilly or mountainous terrain.
•
When doing frequent trailer towing.
•
Uses such as found in taxi, police or delivery
service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
Notice: Use of automatic transaxle fluid labeled
other than DEXRON
®
-III may damage your vehicle,
and the damages may not be covered by your
warranty. Always use DEXRON
®
-III labeled automatic
transaxle fluid.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL
®
engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, 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 5-22.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®
coolant will:
•
Give freezing protection down to
−
34°F (
−
37°C).
•
Give boiling protection up to 265°F (129°C).
•
Protect against rust and corrosion.
•
Help keep the proper engine temperature.
•
Let the warning lights and gages work as they
should.
Notice: Using coolant other than DEX-COOL
®
may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs first. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®
(silicate-free) coolant in your vehicle.
