Injecting Sealant and Air

1

Injecting Sealant and Air

In cold temperatures, the sealant may not flow easily. 
In this situation, warm it up for five minutes before 
using. 

The sealant can permanently stain clothing and other 
materials. Be careful during handling and wipe away 
any spills immediately.

3

WARNING

Tire sealant contains substances that are 
harmful and can be fatal if swallowed.

If accidentally swallowed, do not induce 
vomiting. Drink plenty of water and get 
medical attention immediately.

For skin or eye contact, flush with cool 
water and get medical attention if 
necessary.

Injecting 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.

There are three accessory power sockets:

•

In the console compartment

•

In the front of the center pocket

•

In the left side panel in the cargo area

Accessory Power Sockets

 P. 213

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 using the gauge, turn the air 
compressor off only after the sealant injection is 
complete.

WARNING

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 the vehicle outdoors.

To check the pressure, occasionally turn 
off the compressor and read the gauge.

Injecting Sealant and Air

If the required air pressure is not reached within 10 
minutes, the tire may be too severely damaged for 
the kit to provide the necessary seal, and your vehicle 
will need to be towed.

Jump Starting Procedure

1

Jump Starting

Securely attach the jumper cables clips so that they 
do not come off when the engine vibrates. Also be 
careful not to tangle the jumper cables or allow the 
cable ends to touch each other while attaching or 
detaching the jumper cables.

Battery performance degrades in cold conditions and 
may prevent the engine from starting.

WARNING

A battery can explode if you do not follow 
the correct procedure, seriously injuring 
anyone nearby.

Keep all sparks, open flames, and smoking 
materials away from the battery.
