If a Tire Goes Flat

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. Move the shift lever to 

(

P.

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

(LOCK).

1

Temporarily Repairing a Flat Tire

The kit should not be used in the following situations. 
Instead, contact a dealer or roadside assistance 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 (4 mm).

•

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

•

Damage has been caused by driving with the tire 
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

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.

If the required air pressure is not reached within 15 
minutes, the tire may be too severely damaged for 
the kit to provide the necessary seal, and your vehicle 
will need to be towed.

Changing a Flat Tire

If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually 
to reduce speed. Then, stop in a safe place. Replace the flat tire with a compact 
spare tire. Go to a dealer as soon as possible to have the full size tire repaired or 
replaced.

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

brake.

Vehicles with optional spare tire

Changing a Flat Tire

Periodically check the tire pressure of the compact 
spare. It should be set to the specified pressure. 
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm

2

)

When driving with the compact spare tire, keep the 
vehicle speed under 50 mph (80 km/h). Replace with 
a full size tire as soon as possible.

The compact spare tire and wheel in your vehicle are 
specifically for this model. Do not use them with 
another vehicle. Do not use another type of compact 
spare tire or wheel with your vehicle.

Do not mount tire chains on a compact spare tire. 
If a chain-mounted front tire goes flat, remove one of 
the full-size rear tires and replace it with the compact 
spare tire. Remove the flat front tire and replace it 
with the full size tire that was removed from the rear. 
Mount the tire chains on the front tire.

Do not use a puncture-repairing agent on a flat tire, 
as it can damage the tire pressure sensor.

Do not mount the compact spare on the front. If 
mounted on the front, the compact spare, smaller in 
size than the full-size tire, may damage the 
differential.

If either front tire goes flat, remove the rear tire on 
the same side, and mount the compact spare on the 
rear and the rear tire on the front.
