How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to
use. See “Recommended
Fluids and Lubricants” in the Index.
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
It doesn’t take much fluid, generally less than a pint
(0.5
L). Don’t overfiill. We recommend you use only
fluid labeled
DEXRON@-111, because fluid with that
label
is made especially for your automatic transaxle.
Damage caused by fluid other than
DEXRON-I11 is not
covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid level as

described under “How to Check.”
0 When the correct fluid level is obtained, push the
dipstick back in all
the way.
Superlift Shock Absc :rs (Option)
If you have this option, you can level your vehicle for
different loads. As you need to, add air to the rear shock
absorbers through the air valve, located next to the fuel
filler cap behind the fuel filler door. Always keep
a
minimum pressure of 10- 15 psi (70- 105 kPa).
After you load your vehicle, you can add pressure until
the rear gets back to its normal riding height, but don’t
go above 90 psi (620 kPa).
NOTICE:
Do not use superlifts to raise your vehicle above
its normal riding height.
You can damage your
superlifts or other parts if you drive that way for
long periods.

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
rear edge of the driver’s door, shows the correct
inflation pressures for your tires when they’re cold.
“Cold” means your vehicle
has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
NOTICE:
Don’t let anyone tell you that, underinflation or
overinflation
is all right. It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
0 Too much flexing
Too much heat
0 Tire overloading
0 Bad wear
0. Bad handling
0 Bad fuel economy.
NOTICE: (Continued)
NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire.
It should be at
60 psi (420 Pa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t
tell if your tires are properly inflated
simply by looking .at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back
on the valve stems.
They help prevent leaks by keeping out
dirt and moisture.

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures
are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
Most trips are through dusty
areas.
You frequently tow a trailer or use a carrier on top of
your car. (With some models, you should never tow a
trailer. See “Towing a Trailer” in the Index.)
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One
of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
