WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Mazda specification . Do not use any
special washer fluid such as
windshield water repellent type fluid
or bug wash. They may cause
squeaking, chatter noise, streaking
and smearing. Refer toRefill
capacitiesin this chapter.
State or local regulations on volatile
organic compounds may restrict the
use of methanol, a common
windshield washer antifreeze
additive. Washer fluids containing
non-methanol antifreeze agents should be used only if they provide cold
weather protection without damaging the vehicle’s paint finish, wiper
blades or washer system.
WARNING: If you operate your vehicle in temperatures below
40° F (4.5°C), use washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze protection in cold
weather could result in impaired windshield vision and increase
the risk of injury or accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
WINDSHIELD WIPER BLADES
If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.
Check the wiper blades for wear at least twice a year or when they seem
less effective. Substances such as tree sap and some hot wax treatments
used by commercial car washes reduce the effectiveness of wiper blades.

Changing the wiper blades
1. Pull the wiper arm away from
the vehicle. Turn the blade at an
angle from the wiper arm. Push
the lock pin manually to release
the blade and pull the wiper
blade down toward the
windshield to remove it from
the arm.
2. Attach the new wiper to the
wiper arm and press it into
place until a click is heard.
Replace wiper blades at least once per year for optimum performance.
Poor wiper quality can be improved by cleaning the wiper blades and the
windshield, refer toWindows and wiper bladesin theCleaning
chapter.
To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.
ENGINE OIL
Checking the engine oil
Refer to theservice maintenance sectionfor the appropriate intervals
for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait a few minutes for the oil to drain into
the oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in
P (Park) (automatic transmission) or 1 (First) (manual
transmission).
4. Open the hood. Protect yourself from engine heat.

•If the oil level isbetween the two holes or between the MIN and
MAX marks (depending on application),the oil level is acceptable,
DO NOT ADD OIL.
•If the oil level is below the lower hole or the MIN mark, add enough
oil to raise the level between the two holes or between the MIN-MAX
range.
