Information
Commercial hot waxes applied by automatic car washes have been known to make the windshield difficult to clean.
When the wipers no longer clean adequately, the blades may be worn or cracked, and require replacement.

Do not allow the wiper arm to fall against the windshield, since it may chip or crack the windshield.

3. Install the new blade assembly in the reverse order of removal.
4. Return the wiper arm on the windshield.
CAUTION
To prevent damage to the wiper arms or other components, have an authorized HYUNDAI dealer replace the wiper blade.
