1. Place the jack under the jacking point 

closest to the tire to be changed.

2. Turn the end bracket clockwise as shown in 

the image until the top of the jack contacts 
the jacking point.

How to Set Up the Jack

How to Set Up the Jack

Do not use the jack with people or luggage in the 
vehicle.

Use the jack provided in your vehicle.
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 vehicle while using the jack.

•

Do not put anything on top of or underneath the 
jack.

WARNING

The vehicle can easily roll off the jack, 
seriously injuring anyone underneath.

Follow the directions for changing a tire 
exactly, and no person should place any 
portion of their body under a vehicle that is 
supported by a jack.

Temporarily Repairing a Flat Tire

If the tire has a large cut or is otherwise severely damaged, you will need to have the 
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can 
use the temporary tire repair kit so that you can drive to the nearest service station 
for a more permanent repair.

If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually 
to reduce speed. Then stop in a safe place.

1. Park the vehicle on a firm, level, and non-slippery surface and apply the parking 

brake.

2. Change the gear position to 

(

P.

3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF 

(LOCK).

Vehicles with temporary tire repair kit

1

Temporarily Repairing a Flat Tire

The kit should not be used in the following situations. 
Instead, contact a dealer or roadside assistant to have 
the vehicle towed.

•

The tire sealant has expired.

•

More than one tire is punctured.

•

The puncture or cut is larger than 3/16 inch (4mm).

•

The tire side wall is damaged or the puncture is 
outside the contact area.

•

Damage has been caused by driving with the tires 
extremely under inflated.

•

The tire bead is no longer seated.

•

The rim is damaged.

Do not remove a nail or screw that punctured the 
tire. If you remove it from the tire, you may not be 
able to repair the puncture using the kit.

NOTICE

Do not use a puncture-repairing agent other than the 
one provided in the kit that came with your vehicle. If 
a different agent is used, you may permanently 
damage the tire pressure sensor.

Injecting Sealant and Air

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.

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.
