Engine Coolant Temperature Gage
Your vehicle has an
engine coolant temperature
gage. With the ignition
turned to RUN, this gage
shows the engine
coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot. It means that your engine coolant has
overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-26.
Tire Pressure Light
Your vehicle may have a
tire pressure light.
This light comes on briey when the engine is started
and provides information about tire pressures and
the Tire Pressure Monitoring System.
When the Light is Solid
This indicates that one or more of your tires are
signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC), may accompany the light. SeeDIC
Warnings and Messages on page 3-48for more
information. Stop and check your tires as soon as it is
safe to do so. If underinated, inate to the proper
pressure. SeeTires on page 5-52for more information.
3-39

When the Light Flashes First and Then is
Solid
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light will ash for
about a minute and then stay on solid for the remainder
of the ignition cycle. This sequence will repeat with
every ignition cycle. SeeTire Pressure Monitor System
on page 5-61for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.The check engine light
comes on to indicate that
there is an OBD II
problem and service is
required.
Malfunctions often are indicated by the system before
any problem is apparent. This can prevent more serious
damage to your vehicle. This system is also designed
to assist your service technician in correctly diagnosing
any malfunction.
Notice:If you keep driving your vehicle with this
light on, after a while, the emission controls
might not work as well, your vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by your warranty.

OIL LIFE
Press the information button until OIL LIFE displays.
The engine oil life system shows an estimate of the oil’s
remaining useful life. It shows 100% when the system
is reset after an oil change. It alerts you to change the oil
on a schedule consistent with your driving conditions.
In addition to the engine oil life system monitoring the oil
life, additional maintenance is recommended in the
Maintenance Schedule in this manual. SeeEngine Oil
on page 5-15andScheduled Maintenance on page 6-4.
Always reset the engine oil life system after an oil
change. See “How to Reset the Engine Oil Life System”
underEngine Oil Life System on page 5-19.
COOLANT
Press the information button until COOLANT displays.
This mode shows the temperature of the engine coolant
in either degrees Fahrenheit (°F) or degrees Celsius (°C).
Tire Pressure
If your vehicle has a Tire Pressure Monitor System
(TPMS), the pressure for each tire can be viewed in the
DIC. The tire pressure is shown in either pounds per
square inch (psi) or kilopascals (kPa). Press the
information button until LF ## PSI (kPa) ## RF displays
for the front tires. Press the information button again
until LR ## PSI (kPa) ## RR displays for the rear tires.If a low tire pressure condition is detected by the system
while driving, a message advising you to check the tire
pressure appears in the display. SeeInflation - Tire
Pressure on page 5-60andDIC Warnings and Messages
on page 3-48for more information.
DIC Warnings and Messages
These messages appear if there is a problem detected
in one of your vehicle’s systems.
A message clears when the vehicle’s condition is no
longer present. To acknowledge a message and clear it
from the display, press and hold any of the DIC
buttons. If the condition is still present, the warning
message comes back on the next time the vehicle is
turned off and back on. With most messages, a warning
chime sounds when the message displays. Your
vehicle may have other warning messages.

Antilock Brake System (ABS)
Your vehicle might have the Antilock Brake System
(ABS), an advanced electronic braking system that will
help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will come
on briey when you
start your vehicle.
When you start the engine, or when you begin to drive
away, ABS will check itself. You might hear a
momentary motor or clicking noise while this test is
going on, and you might even notice that the brake
pedal moves or pulses a little. This is normal.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
Remember: ABS does not change the time you need to
get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle
in front of you, you will not have time to apply the brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work for you. You might feel
a slight brake pedal pulsation or notice some noise,
but this is normal.

Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have ABS, you can steer and brake at the same
time. However, if you do not have ABS, your rst
reaction — to hit the brake pedal hard and hold it
down — might be the wrong thing to do. Your wheels
can stop rolling. Once they do, the vehicle cannot
respond to your steering. Momentum will carry it in
whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing you were trying to avoid, or into traffic.
If you do not have ABS, use a “squeeze” braking
technique. This will give you maximum braking while
maintaining steering control. You can do this by pushing
on the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control. If you do have
ABS, it is different. SeeAntilock Brake System (ABS)
on page 4-5.
In many emergencies, steering can help you more than
even the very best braking.
Brake Assist
If your vehicle has ESC with ABS, it also has a brake
assist feature that responds to emergency braking
by generating additional pressure and engaging
the ABS. When this happens, the brake pedal will feel
easier to push. Just hold the brake pedal down
rmly and let the system work for you. You might feel
the brakes vibrate or notice some noise, but this is
normal. The brakes will return to normal operation after
the brake pedal is released.
Brake assist cannot compensate for unsafe driving
practices and braking effectiveness, itself, depends on
the condition of the road, tires, and brakes and
vehicle mass.
Traction Control System (TCS)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that the wheels are spinning too much or
are beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power by closing the throttle and managing engine spark
to limit wheel spin.
If your vehicle has TCS, there is a ESC/TCS button
located on the instrument panel.
