How to Add Automatic Transaxle Fluid
Refer to the Maintenance Schedule to determine
what kind of transaxle fluid to use. See Recommended
Fluids and Lubricants on page 6-12.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at
the dipstick hole to bring it to the proper level.
It does not take much fluid, generally less than
one pint (0.5 L). Do not overfill.
Notice: Use of the incorrect automatic transaxle
fluid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transaxle fluid listed in
Recommended Fluids and Lubricants on page 6-12.
3. After adding fluid, recheck the fluid level as
described under “How to Check Automatic
Transaxle Fluid,” earlier in this section.
4. When the correct fluid level is obtained, push the
dipstick back in all the way.
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 5-23.
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 messages 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 the first maintenance
service after each 25,000 miles (41 500 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.
