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 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

Jump Starting

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

1. Connect the first jumper cable to your 

vehicle’s battery + terminal.

2. Connect the other end of the first jumper 

cable to the booster battery + terminal.

u

Use a 12-volt booster battery only.

u

When using an automotive battery 
charger to boost your 12-volt battery, 
select a lower charging voltage than 15-
volt. Check the charger manual for the 
proper setting.

3. Connect the second jumper cable to the 

booster battery - terminal.

4. Connect the other end of the second 

jumper cable to the engine mounting bolt 
as shown. Do not connect this jumper cable 
to any other part.

5. If your vehicle is connected to another 

vehicle, start the assisting vehicle’s engine 
and increase its rpm slightly.

6. Attempt to start your vehicle’s engine. If it 

turns over slowly, check that the jumper 
cables have good metal-to-metal contact.

■

Jump Starting Procedure

1

Jump Starting

Securely attach the jumper cables 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.

Next thing to do

1. Check that the cooling fan is operating and 

stop the engine once the temperature 
gauge 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 has gone down, resume driving. If it has not gone down, 
contact a dealer for repairs.

How to Handle Overheating

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

Use water as an emergency/temporary measure only.

■

Reasons for the indicator to come on

• The brake fluid is low.
• There is a malfunction in the brake system.

■

What to do when the indicator comes on while driving

Depress the brake pedal lightly to check pedal pressure.
• If normal, check the brake fluid level the next time you stop.
• If abnormal, take immediate action. If necessary, downshift the 

transmission to slow the vehicle using engine braking.

■

Reasons for the indicator to blink

• There is a problem with the electric parking brake system.

■

What to do when the indicator blinks

• Avoid using the parking brake and have your vehicle checked by a 

dealer immediately.

1

If the Brake System Indicator (Red) Comes On or Blinks

Have your vehicle repaired immediately.
It is dangerous to drive with low brake fluid. If there 
is no resistance from the brake pedal, stop 
immediately in a safe place. If necessary downshift 
the gears.

If the brake system indicator and ABS indicator come 
on simultaneously, the electronic brake distribution 
system is not working. This can result in vehicle 
instability under sudden braking.
Have your vehicle inspected by a dealer immediately.

If the Brake System Indicator (Red) blinks at the same 
time when the Brake System Indicator (Amber) comes 
on, the parking brake may not work.
Avoid using the parking brake and have your vehicle 
checked by a dealer immediately.

2 If the Brake System Indicator (Red) Comes 

On or Blinks at the Same Time When the 
Brake System Indicator (Amber) Comes On 
P. 612

If you repeatedly operate the electric parking brake in 
a short period of time, the brake stops operating to 
prevent heating of the system and the indicator 
blinks.
It returns to its original state in approximately 1

Drive carefully and avoid abrupt cornering and hard braking.
Stop your vehicle in a safe place. Check the tire pressure and adjust the 
pressure to the specified level. The specified tire pressure is on a label on 
the driver side doorjamb.

■

What to do when the indicator blinks

Have the tire inspected by a dealer as soon as possible. If the compact

NOTICE

Driving on an extremely underinflated tire can cause

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 
down, the system alerts you as follows:
Below recommended pressure: The beeper 
sounds and exterior lights flash once every five 
seconds.
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.
