If the Battery Is Dead

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

The temperature gauge is at the 

 mark or the engine suddenly loses power.

•

Engine Temperature Too Hot. Do Not Drive. Allow Engine To Cool.

 

message appears 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 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.

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.

■

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

If the Brake System Indicator (Red) Comes 
On or Blinks at the Same Time When the 
Brake System Indicator (Amber) Comes On

 

P. 624

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
