WARNING
■Speed limit when using the compact spare tire (vehicles with a
compact spare tire)
Do not drive at speeds in excess of 50 mph (80 km/h) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Fail-
ure to observe this precaution may lead to an accident causing death or
serious injury.
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to turn off the power
back door main switch ( P. 130). Failure to do so may cause the back
door to operate unintentionally if the power back door switch is acciden-
tally touched, resulting in hands and fingers being caught and injured.
■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 po ssibility of personal injury during a
collision or sudden braking.

■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ When recharging or replacing the battery
●Vehicles with a smart key system: In some cases, it may not be possible to
unlock the doors using the smart key system when the battery is dis-
charged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.
● Vehicles with a smart key system: The engine may not start on the first
attempt after the battery has recharged but will start normally after the sec-
ond attempt. This is not a malfunction.
● Vehicles with a smart key system: The engine switch mode is memorized by
the vehicle. When the battery is reconnected, the system will return to the
mode it was in before the battery was discharged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
● Vehicle with power back door: The power back door must be initialized.
(P. 678)
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
