If you turn the steering wheel to the
f ull lef t or right position repeatedly
while stopping or driving at very low
speed, you may f eel slightly harder
steering due to overheating of the
steering gearbox.For more inf ormation, see page .
Continuously driving under those
conditions could damage the power
steering system.
This indicator normally comes on
when you turn the ignition switch to
the ON (II) position and goes of f
af ter the engine starts. If it comes on
at any other time, there is a problem
in the electric power steering system.
If this happens, stop the vehicle in a
saf e place, and turn of f the engine.
Reset the system by restarting the
engine. The indicator will not turn
of f immediately. If it does not go of f
after driving a short distance, or
comes back on again while driving,
take the vehicle to your dealer to
have it checked. With the indicator
on, the EPS may be of f , making the
vehicle harder to steer. This indicator normally comes on f or
a f ew seconds when you turn the
ignition switch to the ON (II)
position. When the brake system
indicator (amber) is on, there is a
problem with the Cooperative
Control with Regenerative Brake,
Creep Aid System or Brake Assist
(the normal brake operates properly).
Have your vehicle checked by your
dealer.

When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. You
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard.
If you think you can saf ely drive a
short distance to a service station,
proceed slowly, and inf late the tire to
the recommended pressure shown
on the driver’s doorjamb.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you cannot make the low tire
pressure indicator go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.Driving on a signif icantly under
inf lated tire causes the tire to
overheat and can lead to tire failure.
Underinf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly.
Each tire has its own pressure
sensor (not including the spare tire).
If the air pressure of a tire becomes
signif icantly low while driving, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator to come on. Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.

The reading on the vehicle’s
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
When the instant f uel economy is
shownonthedisplay,the
temperature gauge will interrupt on
the display and blink for several
times if the coolant temperature
rises to 224°F (118°C) or more. At
the same time, the beeper sounds
once.
If your vehicle overheats, you should
take immediate action. The only
indicationmaybethetemperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
If you do not see steam or spray,
leave the engine running, and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge reading comes down to the
midpoint, then continue driving.
If the temperature gauge stays at
the red mark, turn of f the engine.
Saf ely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn of f all
the accessories, and turn on the
hazard warning lights.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
reading at the red mark can cause
serious damage to your engine.

Start the engine, and set the
interior temperature to maximum.
Add coolant to the radiator up to
the base of the f iller neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and
ref illed with the proper mixture as
soon as you can.
Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeon page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ).
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page ). Add coolant if the level is
below the MIN mark.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower
bef ore checking the radiator. 8. 9.

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.
