affect the drive-train components:
• AWD system
■Speed limit when using the spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a spare tire is installed on
the vehicle.
The spare tire is not designed for driving at high speeds. Failure to observe this precau-
tion may lead to an accident causing death or serious injury.
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their storage
location to reduce the possibility of personal injury during a collision or sudden brak-
ing.
NOTICE
■Be careful when driving over bumps with the spare tire installed on the vehicle.
The vehicle may become lower when driving with the spare tire compared to when
driving with standard tires. Be careful when driving over uneven road surfaces.
■Driving with tire chains and the spare tire
Do not fit tire chains to the spare tire.
Tire chains may damage the vehicle body and adversely affect driving performance.
■When replacing the tires

■Caution while driving
Observe the following precautions.
Failure to do so may cause an accident.
●The emergency tire puncture repair kit is made exclusively for your vehicle. Do not
use it on other vehicles.
●Do not use the emergency tire puncture repair kit for tires that are a different size
than the specified ones or for any other pu rpose. Doing so may cause the tires to not
be repaired properly.
■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 doctor.
●If sealant gets in eyes or adheres to skin, immediately wash it off with water. If discom-
fort 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 or 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.
●After inflation of the tire has completed, th e sealant may splatter when the hose is dis-
connected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not followed, the
sealant may spray out.
●Keep back from the tire while it is being re paired, as there is a chance of it bursting
while the repair operation is being performed. If you notice any cracks or deforma-
tion of the tire, turn off the compressor switch and stop the repair operation immedi-
ately.
●The repair kit may overheat if operated for a long period of time. Do not operate the
repair kit continuously for more than 35 minutes.
●Parts of the repair kit become hot during operation. Be careful handling the repair kit
during and after operation. Do not touch the metal part connecting the bottle and the
compressor. It will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than the one indi-
cated. If the sticker is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may prevent the SRS air bag from operating properly.

■Ceintures de sécurité
Avec un chiffon ou une éponge, nettoyez à l’aide d’un savon doux et de l’eau
tiède. Vérifiez aussi les ceintures régulièrement pour vous assurer qu’elles ne
présentent pas d’usure excessive, d’effilochage ou de coupures.
Entretien et soin
AVERTISSEMENT
■Dommages et usure de la ceinture de sécurité
Vérifiez périodiquement le système de ceintures de sécurité. Vérifiez qu’il n’y a pas de
coupures, d’effilochures ni de pièces desserrées. N’utilisez pas une ceinture de sécu-
rité endommagée avant qu’elle ne soit remplacée. Les ceintures de sécurité endom-
magées ne peuvent pas protéger les occu pants contre les blessures graves, voire
mortelles.
