If the temperature overheat gauge is no longer in the overheat zone or an engine coolant temperature warning light no longer displays, the vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes.
Keep a safe vehicle distance from the vehicle in front. If the warning does not come back on, continue to drive normally.
If the warning continues, pull over, stop, and park the vehicle right away.
If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Also, see Overheated Engine Protection Operating Mode.
