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
detaching the jumper cables.

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

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.
Have a dealer flush the system with proper antifreeze

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.

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
