If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergency
towing eyelet. This should only be attempted on hard surfaced roads
for at most 80 km (50 miles) at under 30 km/h (18 mph).
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.

WARNING
■When using the compact spare tire
● Remember that the compact spare tire provided is specifically designed
for use with your vehicle. Do not use your compact spare tire on another
vehicle.
● Do not use more than one compact spare tire simultaneously.
● Replace the compact spare tire with a standard tire as soon as possible.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
■ When the compact spare tire is attached
The vehicle speed may not be correctly detected, and the following systems
may not operate correctly:
• ABS
• Brake assist
• VSC (if equipped)
• TRC (if equipped)
• PCS (Pre-Crash Safety system) (if equipped)
• LDA (Lane Departure Alert) (if equipped)
• EPS
• Tire pressure warning system (if equipped)
■ Speed limit when using the compact spare tire
Do not drive at speeds in excess of 80 km/h (50 mph) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Failure to
observe this precaution 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 braking.
■ Replacing a flat tire (vehicles with a steel wheel)
Never use tools, such as an Allen
wrench, that are used by applying them
to a hexagonal concave portion of a bolt
head. Doing so could cause bolt defor-
mation and improper installation, and
may result in serious injury.

WARNING
■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.
● To avoid risk of burst or severe leakage, do not drop or damage the bottle.
Visually inspect the bottle before use. Do not use a bottle with shock,
crack, scratch, leakage or any other damage. In such case, immediately
replace.
● 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.
● After inflation of the tire has completed, the sealant may splatter when the
hose is disconnected or some air is let out of the tire.
● Follow the operation procedure to repair the tire. If the procedures not fol-
lowed, the sealant may spray out.
● Keep back from the tire while it is being repaired, as there is a chance of it
bursting while the repair operation is being performed. If you notice any
cracks or deformation of the tire, turn off the compressor switch and stop
the repair operation immediately.
● The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 40 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 around
the connecting area between 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 indicated. 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.
