again before the rst 10 minutes of engine running time
has expired, 10 minutes are added to the remaining
minutes. For example, if the lock button and then
the remote start buttons are pressed again after
ve minutes of the engine run time, 10 minutes are
added and you now have 15 minutes of engine running.
The added ten minutes are considered a second
remote vehicle start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
with the ignition key before you can use the remote
start feature again.
The remote vehicle start feature will not operate if the
key is in the ignition, the hood is not closed, or if there is
an emission control system malfunction.
The engine will turn off during a remote vehicle start if
the coolant temperature gets too high, or the oil pressure
is too low.Your vehicle was shipped from the factory with the
remote vehicle start system enabled. The system
may be disabled through the Driver Information
Center (DIC). See “REMOTE START” underDIC
Vehicle Customization on page 3-86for additional
information.
SeeEngine Exhaust on page 2-36for important safety
information when using remote start in a closed
garage.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature.
This feature allows your dealer/retailer to add the
manufacturer’s remote vehicle start feature. See your
dealer/retailer if you would like to add the manufacturer’s
remote vehicle start feature to your vehicle.

Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver side
of the engine, behind the transmission dipstick/uid
ll location and next to the engine.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a re. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt AC outlet. If the cord will not reach,
use a heavy-duty three-prong extension cord
rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts and prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.

Lane Departure Warning (LDW)
Light
For vehicles with the lane
departure warning system,
this light briey comes
on amber, while starting
the vehicle, to indicate
that it is working.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
When driving at speeds of 35 mph (56 km) or greater
and LDW is turned on, a green warning symbol appears
when the system has detected lane markings on at
least one side of the vehicle.
For more information seeLane Departure Warning
(LDW) on page 2-49.When LDW is active, the amber warning symbol comes
on and ashes. Three beeps sound if a lane marking
is crossed without using the turn signal. If the warning
symbol is not on, LDW is not operating and will not
warn when the vehicle crosses a lane marking.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light comes on when
the engine is very hot.
This light also comes on briey when the vehicle is
started.
If the light does not go out or comes on and stays on
while driving, there may be a problem with the cooling
system. Driving with engine coolant temperature light
on could cause the vehicle to overheat, seeOverheated
Engine Protection Operating Mode on page 5-30.
SeeEngine Overheating on page 5-28andDIC Warnings
and Messages on page 3-73for more information.

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
It indicates when the engine has warmed up and if
the cooling system is operating properly. If the gage
pointer moves into the shaded area, the engine coolant
is too hot and the engine coolant temperature warning
light comes on. SeeEngine Overheating on page 5-28
for more information.
Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes
on briey when the engine
is started.
It provides information about tire pressures and the
Tire Pressure Monitoring System.

ENGINE HOT – A/C
(Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
SeeEngine Coolant Temperature Gage on page 3-60.
To avoid added strain on a hot engine, the air
conditioning compressor automatically turns off.
When the coolant temperature returns to normal,
the air conditioning compressor turns back on.
You can continue to drive your vehicle.
If this message continues to appear, have the system
repaired by your dealer/retailer as soon as possible
to avoid damage to the engine.
ENGINE OVERHEATED IDLE ENGINE
Notice:If you drive your vehicle while the engine
is overheating, severe engine damage may occur.
If an overheat warning appears on the instrument
panel cluster and/or DIC, stop the vehicle as soon as
possible. Do not increase the engine speed above
normal idling speed. SeeEngine Overheating
on page 5-28for more information.This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle
to idle until it cools down. SeeEngine Coolant
Temperature Warning Light on page 3-59.
SeeOverheated Engine Protection Operating Mode on
page 5-30for information on driving to a safe place
in an emergency.
ENGINE OVERHEATED STOP ENGINE
Notice:If you drive your vehicle while the engine
is overheating, severe engine damage may occur.
If an overheat warning appears on the instrument
panel cluster and/or DIC, stop the vehicle as soon
as possible. SeeEngine Overheating on page 5-28
for more information.
This message displays when the engine has overheated.
Immediately look for a safe place to pull your vehicle
over and turn the engine off right away to avoid severe
engine damage. SeeEngine Overheating on page 5-28
andOverheated Engine Protection Operating Mode
on page 5-30. A chime also sounds when this message
is displayed.
