Displaying the coolant temperature
WARNING
Driving when your engine is overheated can
cause some fluids which may have leaked into the engine compartment to catch
fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
► Press the
button on the
steering wheel to select the standard
display.
► Press the
button to select the
coolant temperature.

Under normal driving conditions, with the correct anti-corrosion and antifreeze additive concentration, the reading may rise to 248 °F(120 °C).
If the coolant temperature exceeds
248 °F(120 °C) do not continue driving. The
engine will otherwise be damaged.
