Extending Engine Run Time
To extend the engine run time by
10 minutes, repeat Steps 1 though 3
while the engine is still running. The
engine run time can only be
extended if it is the first remote start
since the vehicle has been driven.
Remote start can be extended
one time.
If the remote start procedure is
used again before the first
10 minute time frame has ended,
the first 10 minutes will immediately
expire and the second 10 minute
time frame will start.
For example, if the lock button and
then the remote start buttons are
pressed again after the vehicle has
been running for five minutes,
10 minutes are added, allowing the
engine to run for a total of
15 minutes.A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles.
After the vehicle's engine has been
started two times using the remote
start button, the ignition must be
turned on and then back off before
the remote start procedure can be
used again.
Shutting the Engine Off After a
Remote Start
To manually shut off a remote start:
.Aim the RKE transmitter at the
vehicle and press
/until the
parking lamps turn off.
.Turn on the hazard warning
flashers.
.Turn the ignition switch on and
then off.
Conditions in Which the
Remote Start Will Not Work
The vehicle cannot be started using
the remote start feature if the key is
in the ignition, the hood is open, or if
there is an emission control system
malfunction.
The engine turns off during a remote
start if the coolant temperature gets
too high or if the oil pressure
gets low.
Vehicles that have the remote
vehicle start feature are shipped
from the factory with the remote
vehicle start system enabled. The
system may be enabled or disabled
through the DIC if the vehicle has
DIC buttons. See “REMOTE
START” underVehicle
Personalization (With DIC Buttons)
on page 5‑44for additional
information. If the vehicle does not
have DIC buttons, see your dealer/
retailer to enable or disable the
remote start system.

Engine Coolant
Temperature Gage
United StatesCanada
This gage shows the engine coolant
temperature. Under normal driving
conditions the gage will read
approximately 100 °C (210°F) or
less. If the gage pointer is near
125 °C (260°F), the engine is
too hot.
It means that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle and turn off the engine as
soon as possible.
See Engine Overheating
on
page 10‑19for more information.
Voltmeter Gage
When the engine is not running, but
the ignition is turned on, this gage
shows the battery's state of charge
in DC volts.
When the engine is running, this
gage shows the condition of the
charging system. The vehicle's
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may fluctuate.
This is normal. Readings between
the low and high warning zones
indicate the normal operating range.
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
idling for an extended period. If there is a problem with the battery
charging system, a SERVICE
BATTERY CHARGING SYSTEM
message will appear in the Driver
Information Center (DIC) and/or the
charging system light comes on.
See
Battery Voltage and Charging
Messages
on page 5‑35for more
information.
However, readings in either warning
zone may indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.
