Lockout Protection
Your vehicle can be programmed to sound the
horn three times and unlock the driver’s door when
both doors are closed and there is a keyless
access transmitter inside the vehicle. When the
driver’s door is opened, a reminder chime will
sound continuously. The vehicle will remain locked
only when at least one transmitter has been
removed from the vehicle and both doors are
closed. SeeDIC Vehicle Personalization on
page 220.
Trunk
{CAUTION:
It can be dangerous to drive with the
trunk lid open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the trunk lid open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle. See
Climate Control System.
If you have air outlets on or under
the instrument panel, open them all
the way.
SeeEngine Exhaust on page 102.

Ashtray(s) and Cigarette Lighter
The ashtray and cigarette lighter are located under
a lid in the front console to the right of the shift
lever. Press the left side of the lid and it will open
automatically.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle. Never
put ammable items in the ashtray.
Loose objects, such as paper clips, can lodge
behind and beneath the ashtray lid and prevent
movement of the lid. You should avoid putting
small, loose objects near the ashtray.
To use the cigarette lighter, push it in all the way
and let go. When it is ready, it will pop back
out by itself.
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in
while it is heating.
Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, and ventilation for the vehicle.
When your vehicle is rst started, the system will
recall the last temperature fan and mode
settings for that driver.

If you turn off the StabiliTrak®system, by pressing
the front part of the button on the console for
ve seconds, the TCS light will come on, a chime
will sound and the TRAC/STABILITRAK OFF
message will be displayed in the DIC. The TCS
will also be turned off. SeeDIC Warnings and
Messages on page 206for more information.
If the StabiliTrak
®system and TCS are turned off,
pressing the console button momentarily will
turn both systems on. The DIC will display the
TRAC/STABILITRAK ON message, the instrument
cluster light will be off and a chime will sound.
SeeDIC Warnings and Messages on page 206for
more information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
As the pointer nears 260°F (125°C), your
engine coolant temperature is high. A message
may display on the Driver Information Center (DIC)
depending on how high the temperature is. See
DIC Warnings and Messages on page 206
for more information.
SeeEngine Overheating on page 388for more
information.

CLEAN RADAR CRUISE
If your vehicle has this feature, this message
displays when the Adaptive Cruise Control (ACC)
system is disabled because the radar is blocked
and cannot detect vehicles in your path. It
may also activate during heavy rain or due to road
spray. To clean the system, seeAdaptive Cruise
Control on page 150.
CLOSE CARGO DIVIDER
This message displays if the cargo divider is not in
place. Open the trunk and make sure the cargo
divider is secure and no objects are on the divider.
SeeRear Storage Area on page 123for more
information.
COOLANT OVER TEMP (Temperature)
This message displays when the engine coolant
temperature is too hot. Stop and allow your vehicle
to idle in PARK (P) until it cools down and the
message is removed. Do not increase engine
speed above a normal idle. If it does not
cool down, turn off the engine and have your
vehicle serviced by your dealer before driving itagain. Severe engine damage can result from an
overheated engine. SeeEngine Overheating
on page 388.

the Traction Control System (TCS) and
StabiliTrak
®System will also be disabled. The
Driver Information Center will scroll three
messages: SERVICE ABS, SERVICE TRACTION
SYS, and SERVICE STABILITRAK, and the
anti-lock brake system and traction control warning
lights on the instrument panel cluster will beilluminated. SeeAnti-Lock Brake System Warning
Light on page 193andTraction Control System
(TCS) Warning Light on page 194. The driver can
acknowledge these messages by pressing the

Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 388.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Giving freezing protection down to−34°F
(−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
385

Adding Coolant
If you need more coolant, add the proper
DEX-COOL®coolant mixture at the surge tank,
but only when the engine is cool.
{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
When replacing the pressure cap, press down and
turn it clockwise until you hear a clicking sound.
Make sure the cap is hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. SeeEngine
Compartment Overview on page 374for more
information on location.
Engine Overheating
You will nd a COOLANT OVER TEMP message
or an ENGINE HOT, STOP ENGINE message
displayed in the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 206.
You will also hear a chime.
There is also an engine coolant temperature gage
on the instrument panel cluster. SeeEngine
Coolant Temperature Gage on page 195.
388

A low coolant level should be indicated by a LOW
COOLANT message on the Driver Information
Center (DIC). If it is, you may have a leak at the
pressure cap or in the radiator hoses, heater
hoses, radiator, water pump, or somewhere else
in the cooling system.
{CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Do not
touch them. If you do, you can be burned.
Do not run the engine if there is a leak. If
you run the engine, it could lose all
coolant. That could cause an engine re,
and you could be burned. Get any leak
xed before you drive the vehicle.
If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, your vehicle
needs service.Notice:Engine damage from running your
engine without coolant is not covered by your
warranty. SeeOverheated Engine Protection
Operating Mode on page 390for information on
driving to a safe place in an emergency.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant could require changing sooner, at
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
