If the fluid level is low, add only enough of the proper
fluid to bring the level into the crosshatched 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 transmission
fluid may damage your vehicle, and the damages
may not be covered by your warranty. Always use
the automatic transmission 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
Transmission 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 the vehicle is filled with
DEX-COOL
®
engine coolant. This coolant is designed
to remain in the vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first, if only
DEX-COOL
®
extended life coolant is added.
The following explains the cooling system and how to
add coolant when it is low. If there is a problem with
engine overheating or if coolant needs to be added to the
radiator, see Engine Overheating on page 5-27.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®
engine 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 the first maintenance
service after each 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.
