Cadillac XT4 2023 Owner's Manual page 416

The vehicle may have a
shutter system designed to
help improve fuel economy.
Keep the shutter system clear
of debris, snow and ice. If the
check engine light is activated,
please check to see if the
shutter system is clear of
debris, snow or ice.
Windshield and Wiper
Blades
Clean the outside of the
windshield with glass cleaner.
Clean rubber blades using a
lint-free cloth or paper towel
soaked with windshield
washer fluid or a mild
detergent. Wash the
windshield thoroughly when
cleaning the blades. Bugs,
road grime, sap, and a buildup
of vehicle wash/wax
treatments may cause wiper
streaking.
Replace the wiper blades if
they are worn or damaged.
Damage can be caused by
extreme dusty conditions,
sand, salt, heat, sun, snow,
and ice.
Weatherstrips
Apply weatherstrip lubricant
on weatherstrips to make
them last longer, seal better,
and not stick or squeak.
Lubricate weatherstrips at
least once a year. Hot, dry
climates may require more
frequent application. Black
marks from rubber material on
painted surfaces can be
removed by rubbing with a
clean cloth. See
Recommended Fluids and
Lubricants 0 429.
Tires
Use a stiff brush with tire
cleaner to clean the tires.
Caution
Using petroleum-based tire
dressing products on the
vehicle may damage the
paint finish and/or tires.
(Continued)
Vehicle Care
Caution (Continued)
When applying a tire
dressing, always wipe off
any overspray from all
painted surfaces on the
vehicle.
Wheels and Wheel Trim
Use a soft, clean cloth with
mild soap and water to clean
the wheels. After rinsing
thoroughly with clean water,
dry with a soft, clean towel.
A wax may then be applied.
Caution
Chrome wheels and chrome
wheel trim may be damaged
if the vehicle is not washed
after driving on roads that
have been sprayed with
magnesium chloride or
calcium chloride. These are
used on roads for conditions
such as dust and ice. Always
wash the chrome with soap
and water after exposure.
