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, do either of the 
following operations:
• Press and hold the ENGINE START/STOP button for about two seconds.
• Firmly press the ENGINE START/STOP button three times.

The steering wheel will not lock. However, because turning off the engine 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. Use 
both feet on the brake pedal to slow down the vehicle and stop immediately in a 
safe place.

The gear position automatically changes to 

(

P after the vehicle comes to a complete 

stop. Then, the power mode changes to VEHICLE OFF.

The gear position automatically changes to

Jump Starting

Turn off the power to electric devices, such as audio and lights. Turn off the engine, 
then open the hood.

1. Open the battery terminal cover.

■

Jump Starting Procedure

1

Jump Starting

Securely attach the jumper cable clips so that they do 
not come off when the engine vibrates. Also be 
careful not to tangle the jumper cables or allow the 
cable ends to touch each other while attaching or 
detaching the jumper cables.

Battery performance degrades in cold conditions and 
may prevent the engine from starting.

3

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.

on the multi-information display.

• Steam or spray comes out of the engine compartment.

■

First thing to do

1. Immediately park the vehicle in a safe place.
2. Turn off all accessories and turn on the hazard warning lights.

u

No steam or spray present: Keep the engine running and open the hood.

■

Next thing to do

1. Check that the cooling fan is operating and 

stop the engine once the temperature 
gauge needle comes down.

u

If the cooling fan is not operating, 
immediately stop the engine.

2. Once the engine has cooled down, inspect 

the coolant level and check the cooling 
system components for leaks.

u

If the coolant level in the reserve tank is 
low, add coolant until it reaches the 
MAX mark.

u

If there is no coolant in the reserve tank, 
check that the radiator is cool. 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.

■

Last thing to do

Once the engine has cooled sufficiently, restart it and check the temperature gauge. 
If the temperature gauge needle has gone down, resume driving. If it has not gone 
down, contact a dealer for repairs.

1

How to Handle Overheating

If the coolant is leaking, contact a dealer for repairs.

Use water as an emergency/temporary measure only. 
Have a dealer flush the system with proper antifreeze 
as soon as possible.

Continuing to drive with the Stop Driving When 
Safe. Engine Temperature Too Hot message on 
the multi-information display may damage the 
engine.

3

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.

inflate your tires to the prescribed level.

TPMS Fill Assist provides visual and audible assistance 
during tire pressure adjustment. With the power 
mode in ON, while you adjust tire pressure up or

At recommended pressure: The beeper sounds 
and exterior lights flash rapidly for ~ five seconds.
Above recommended pressure: The beeper 
sounds and lights flash twice every three seconds.
