CAUTION
Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelet and the cable or chain. Always be
cautious of the surroundings and other vehicles while towing.
Except hybrid vehicle (vehicles without a smart entry & start system): Do
not turn the engine switch to the “LOCK” position.
Except hybrid vehicle (vehicles with a smart entry & start system): Do not
turn the “ENGINE START STOP” switch off.
Doing so will lock the steering wheel and prevent operation, possibly caus-
ing an accident and resulting in death or serious injury.
Hybrid vehicle (vehicles without an electronic key): Do not turn the engine
switch to the “LOCK” position.
Hybrid vehicle (vehicles with an electronic key): Do not turn the “POWER”
switch off.
This may lead to accidents because the steering wheel will be locked and
you will not be able to operate the steering wheel.
Except hybrid vehicle: If the engine is not running, the power assist for the
brakes and steering will not function, making steering and braking more
difficult.
Hybrid vehicle: If the hybrid system is off, the power assist for the brakes
and steering will not function, making steering and braking more difficult.
Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing. This
may lead to accidents that cause serious injury or even death.

CAUTION
Using the tire jack
Improper use of the tire jack may cause the vehicle to suddenly fall off the
jack, leading to death or serious injury.
Do not use the tire jack for any purpose other than replacing tires or install-
ing and removing tire chains.
Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replac-
ing tires on this vehicle.
Always check that the tire jack is securely set to the jack point.
Do not put any part of your body under the vehicle while it is supported by
the jack.
Do not start or run the engine (except hybrid vehicle) or hybrid system
(hybrid vehicle) while your vehicle is supported by the jack.
Do not raise the vehicle while someone is inside.
When raising the vehicle, do not put an object on or under the jack.
Do not raise the vehicle to a height greater than that required to replace
the tire.
Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that no one working
on or near the vehicle may be injured.

CAUTION
Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
Driving with a flat tire may cause a circumferential groove on the side wall. In
such a case, the tire may explode when using a repair kit.
Caution while driving
Store the repair kit in the luggage room.
Injuries may result in the event of an accident or sudden braking.
The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
Do not use repair kit for tires that are different size than the original ones,
or for any other purpose. If the tires have not been completely repaired, it
could lead to an accident causing death or serious injury.
Precautions for use of the sealant
Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a doc-
tor.
If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
When fixing the flat tire
Stop your vehicle in a safe and flat area.
Do not touch the wheels or the area around the brakes immediately after
the vehicle has been driven.
After the vehicle has been driven, the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands, feet or
other body parts may result in burns.
Connect the valve and hose securely with the tire installed on the vehicle.
If the hose is not properly connected to the valve, air leakage may occur
as sealant may be sprayed out.
If the hose comes off the valve while inflating the tire, there is a risk that
the hose will move abruptly due to air pressure.

CAUTION
If the engine has to be turned off while driving (except hybrid vehicle)
Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
Vehicles without a smart entry & start system: Never attempt to remove
the key, as doing so will lock the steering wheel.
If the hybrid system has to be turned off while driving (hybrid vehicle)
Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the hybrid system.
Vehicles without an electronic key: Never attempt to remove the key, as
doing so will lock the steering wheel.
