closest to the tire to be changed.
2. Turn the end bracket cl ockwise as shown in 
the image until the top of the jack contacts 
the jacking point.
u Make sure that the jacking point tab is 
resting in the jack notch.
3. Raise the vehicle, using the jack handle bar 
and the jack handle, until the tire is off the 
ground.
■How to Set Up the Jack1How to Set Up the Jack

Other jacks may not support  the weight (“load”) or 
may not fit the jacking point.
The following instructions must be followed to use 
the jack safely:
•Do not use while the engine is running.
•Use only where the ground is firm and level.•Use only at the jacking points.
•Do not get in the vehicl e while using the jack.
•Do not put anything on top of or underneath the 
jack.

NOTICE
Do not operate the temporary tire repair kit compressor 
for more than 15 minu tes. 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 2 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 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.

Then drive carefully for 10 more minutes or 
until you reach the nearest service station, 
whichever is sooner. Do not exceed 50 mph 
(80 km/h). If you have not reached a service 
station, stop and check the tire pressure.
u You should repeat this procedure as long 
as the air pressure is  within this range.
6. Unscrew the sealant/ai r hose from the tire 
valve stem.
Reinstall the valve cap.
7. Press the pressure relief button until the 
gauge returns to 0 psi (0 kPa).
8. Repackage and properly stow the kit.
