Emergency Power System Stop; Overheating - Acura MDX SPORT HYBRID 2018 Owner's Manual

HANDLING THE UNEXPECTED
WARNING
A battery can explode if you do not follow the correct procedure, seriously
injuring anyone nearby.
Keep all sparks, open flames, and smoking materials away from the battery.
After the Engine Starts
Once your vehicle's power system has started, remove the jumper cables in the
following order:
1. Disconnect the jumper cable from your vehicle's ground.
2. Disconnect the other end of the jumper cable from the booster battery (-)
terminal.
3. Disconnect the jumper cable from your vehicle's 12-volt battery (+) terminal.
4. Disconnect the other end of the jumper cable from the booster battery (+)
terminal.
5. Have your vehicle inspected by a nearby service station or a dealer.

Emergency Power System Stop

The POWER button may be used to stop the power system due to an emergency
situation even while driving. If you must stop the power system, choose one of the
following operations:
• Press and hold the POWER button for two
seconds, OR
• Firmly press the POWER button three times.
The steering wheel will not lock. The power mode changes to ACCESSORY, unless
the gear 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.
NOTICE
Do not press the button while driving unless it is absolutely necessary for the
power system to be switched off.

Overheating

If you see the multi-information display (MID) message "Stop Driving When Safe.
Engine Temperature Too Hot," your engine is overheating. You may also notice the
temperature gauge is at the H mark or the engine suddenly loses power. Steam or
spray may come out from under the hood.
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 power
system running and open the hood (see page
136).
If steam or spray is present: Turn off the power
system and wait until it subsides. Then open the
hood.
3. Check that the cooling fan is operating. If it is not, immediately stop the power
system. Otherwise, idle the engine until the MID message goes off.
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. Then, fill the reserve tank to the MAX mark.
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.
