CAUTION
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.
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
installing 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 hybrid system 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 work-
ing on or near the vehicle may be injured.
