Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.

• Make sure to follow the instructions indicated on the automated car wash.
• Fold in the door mirrors.
• For models equipped with automatic inte rmittent wipers, turn the wipers off.
• Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. St anding too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.

6.Turn the selector switch to REPAIR.
1Injecting Sealant and Air
NOTICE
Do not operate the temporary tire repair kit
compressor for more than 15 minutes. The
compressor can overheat and become permanently
damaged.
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begin to rise again as the
tire is inflated with air. This is normal. To accurately
measure the air pressure usi ng the gauge, turn the air
compressor off only after the sealant injection is
complete.
3WARNING
Running the engine with the vehicle in an
enclosed or even partly enclosed area can
cause a rapid build-up of toxic carbon
monoxide.
Breathing this colorless, odorless gas can
cause unconsciousness and even death.
Only run the engine to power the air
compressor with th e vehicle outdoors.
