Starting Fluids
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are followed,
the engine should start in all conditions and no type of
starting fluid should be used.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
• When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the key fob
from the vehicle, and lock the vehicle.

WARNING! (Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the transmission gear selector. Do not leave the
key fob in or near the vehicle (or in a location
accessible to children), and do not leave the igni-
tion (of a vehicle equipped with Keyless Enter-N-
Go™) in the ACC or ON/RUN mode. A child could

REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
• The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
• The Remote Start system will wait for the “Wait To
Start” telltale to extinguish before cranking the engine.
This allows time for the intake heater to pre-heat the
incoming air, and is normal operation in cold weather.
Refer to “Wait To Start” in “Understanding Your
Instrument Panel”.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
• Transmission in PARK
• Doors closed
• Hood closed
• HAZARD switch off
• BRAKE switch inactive (brake pedal not pushed)
• Ignition key removed from ignition switch
• Battery at an acceptable charge level
• RKE PANIC button not pushed
• Fuel meets minimum requirement
• Water In Fuel Indicator Light is not illuminated
• Wait To Start Light is not illuminated

WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Mon-
oxide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious in-
jury or death when inhaled.
• Keep Remote Keyless Entry (RKE) transmitters
away from children. Operation of the Remote Start
System, windows, door locks or other controls
could cause serious injury or death.
Remote Start Abort Message
The following messages will display in the EVIC/DID if
the vehicle fails to remote start or exits remote start
prematurely:
• Remote Start Aborted - Door Ajar
• Remote Start Aborted - Hood Ajar •
Remote Start Aborted - Fuel Low
• Remote Start Aborted - System Fault
The EVIC/DID message stays active until the ignition is
turned to the ON/RUN position.
To Enter Remote Start Mode
Push and release the REMOTE START button
on the RKE transmitter twice, within five sec-
onds. The parking lights will flash and the horn
will chirp twice (if programmed). In cold am-
bient temperature conditions, the diesel vehicle may
delay crank up to 30 seconds for the fuel and grid heater.
Once the vehicle has started, the engine will run for 15
minutes or 75 seconds in extreme cold and high
elevation.

The cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch. 12. Electric Power Steering Malfunction Warning Light
— If Equipped
This telltale is on when the Electric Power

13. Electronic Throttle Control (ETC) Light This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the transmission is
placed in the PARK position. The light should turn off.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
The starter should not be operated for more than 15-
second intervals. Waiting a few minutes between such
intervals will protect the starter from overheating.

vehicles in hot weather. Interior heat build up may
cause serious injury or death.
• When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the key fob
from the vehicle, and lock the vehicle.
