overheating

If the temperature gauge needle is at the H mark, the engine suddenly loses power, or
steam or spray comes out from under the hood, your engine is overheating.
1. Immediately park the vehicle in a safe place. Turn off all
accessories and turn on the hazard warning lights.
2. If no steam or spray is present: Keep the engine
running and open the hood (see page 124).
If steam or spray is present: Turn off the engine and wait
until it subsides. Then, open the hood.
3. Check that the cooling fan is operating and stop the engine once the temperature gauge
needle goes down. If the cooling fan is not operating, immediately stop the engine.
4. Once the engine has cooled down, inspect the coolant level and check the cooling
system components for leaks. If the coolant level in the reserve tank is low, add coolant
until it reaches the MAX mark. If there is no coolant in the reserve tank, make sure the
radiator is cool, then cover the radiator cap with a heavy cloth and open the cap. If
necessary, add coolant up to the base of the filler neck, and put the cap back on.
Once the engine has cooled sufficiently, restart it and check the temperature gauge. If the
temperature needle has gone down, resume driving. If it has not gone down, contact a
dealer for repairs.
WArNING
Steam and spray from an overheated engine can seriously scald you.
Do not open the hood if steam is coming out.
WArNING
Removing the radiator cap while the engine is hot can cause the coolant to
spray out, seriously scalding you.
Always let the engine and radiator cool down before removing the radiator
cap.
NoTICe
Continuing to drive with the temperature gauge needle at the H mark may damage the
engine.

emergency engine Stop

The ENGINE START/STOP button may be used to stop the engine due to an emergency
situation even while driving. If you must stop the engine, choose one of the following
operations:
Reserve tank MAX MIN
• Press and hold the ENGINE START/STOP button for two
• Firmly press the ENGINE START/STOP button two times.
The steering wheel will not lock. The power mode changes to ACCESSORY (unless the shift
lever is in Park, in which case the power mode changes to VEHICLE OFF).
Because turning off the engine also disables the power assist the engine provides to the
steering and braking systems, it will require significantly more physical effort and time
to steer and slow the vehicle. Downshift gears and use both feet on the brake pedal, if
necessary, to slow the vehicle and stop immediately in a safe place.
Do not press the button while driving unless it is absolutely necessary for the engine to be
switched off.

Tire Pressure monitoring System (TPmS)

Monitors the tire pressure while you are driving.
If your vehicle's tire pressure becomes significantly low, the low tire pressure indicator
comes on and a message appears on the multi-information display.
Driving on an extremely underinflated tire can cause it to overheat. An overheated tire can
fail. Always inflate your tires to the specified pressure.
