Handling the Unexpected
■ Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the high temperature
indicator goes off.
uIf 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.
uIf the coolant level in the reserve tank is
low, add coolant until it reaches the MAX mark.
uIf 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 co oled sufficiently, restart it and check the high temperature
indicator.
If the high temperature indicator is off, resume driving. If it stays on, contact a dealer
for repairs.
1How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emerge ncy/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
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.MAX

uuIndicator, Coming On/BlinkinguIf the Brake System Indicator Comes On
Handling the Unexpected
If the Brake System Indicator Comes On■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
Press 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.
If the EPS Indicator Comes On
■Reasons for the indicator to come on
• Comes on when there is a problem with EPS.
• If you depress the accelerator pedal repeatedly to increase the engine
speed while the engine is idling, the indicator comes on, and
sometimes the steering wheel becomes harder to operate.
■ What to do when the indicator comes on
Stop the vehicle in a safe place and restart the engine.
If the indicator comes on and stays on, immediately have your vehicle
inspected by a dealer.
1If the Brake System Indicator Comes On
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.U.S.

1If the EPS Indicator Comes On
NOTICE
If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel on
the full left or right position for a while, the system
heats up. The system goes into a protective mode,
and limits its performance. The steering wheel
becomes harder and harder to operate. Once the
system cools down, EPS is restored. Repeated operation under these conditions can eventually damage the system.
