Additional Maintenance
and Care
Windshield
For safety, appearance, and the best
viewing, keep the windshield clean and
clear.
.
Signs of damage include scratches, cracks,
and chips.
.
Trained dealer technicians can inspect the
windshield and recommend proper
replacement if needed.
Clean the outside of the windshield with
glass cleaner.
Wiper Blades
Wiper blades need to be cleaned and kept in
good condition to provide a clear view.
.
Signs of wear include streaking, skipping
across the windshield, and worn or split
rubber.

Trained dealer technicians can check the
wiper blades and replace them when
needed.
Clean rubber blades using a lint-free cloth or
paper towel soaked with windshield washer

blades. Bugs, road grime, sap, and a buildup
of vehicle wash/wax treatments may cause
wiper streaking.

damaged. Damage can be caused by
extreme dusty conditions, sand, salt, heat,
sun, snow, and ice.
Interior Glass
To clean, use a microfiber cloth fabric
dampened with water. Wipe droplets left
behind with a clean dry cloth. If necessary,
use a commercial glass cleaner after
cleaning with plain water.
