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.

Immediatel
y 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
115).
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.
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.
WARNING
Continuing to drive with the temperature gauge needle at the H mark may
damage the engine.
NOTICE
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:
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.
• Press and hold the ENGINE START/STOP button for two seconds, or
•

Firml
y press the ENGINE START/STOP button two
times.
Trying to lift or tow your vehicle by the bumpers will cause serious damage. The
bumpers are not designed to support the vehicle’s weight.
Improper towing such as towing behind a motorhome or other motor vehicle can
damage the transmission.
NOTICE
Emergency Towing
Call a professional towing service if you need to tow your vehicle.
Flat bed equipment: The operator loads your vehicle on the back of a truck. This is
the only way you can safely transport your vehicle. Any other towing method
will damage the vehicle’s drive system.
