If a Tire Goes Flat

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, non-slippery surface and apply the parking brake.

2.

Change the gear position to

3.

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

Vehicles with a compact spare tire

1

Changing a Flat Tire

Follow compact spare precautions:
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.

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 never get under the vehicle
when it is supported only by the 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.

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

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

CAUTION

Tire sealant contains substances that are
harmful if inhaled, ingested or if contact is
made with the eyes or skin.

Always use in a well-ventilated area and
use gloves and safety glasses for protection;
do not ingest.

For skin or eye contact, flush with cool
water; if ingested, rinse mouth with water.
In all cases, seek 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 10

will need to be towed.

and proper disposal of an empty bottle.
