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
•TRC
• PCS (Pre-Collision 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.
