REMOTE START— IF EQUIPPED (DIESEL)
This system uses the key fob to start

approximately 300 ft (91 m).
NOTE:
Obstructions between the vehicle and the
key fob may reduce this range.
The Remote Start system will wait for the
Wait To Start indicator light to extinguish
before cranking the engine. This allows time
for the intake heater to preheat the incoming
air, and is normal operation in cold weather.

Doors closed
Hood closed
Hazard switch off
Brake switch inactive (brake pedal not
pushed)
Battery at an acceptable charge level
PANIC button not pushed
Fuel meets minimum requirement
Water In Fuel Indicator Light is not illumi -
nated
Wait To Start Light Indicator Light is not illu -

REMOTE START ABORT MESSAGE
The following messages will display in the
instrument cluster display if the vehicle fails to
remote start or exits remote start prematurely:
Remote Start Aborted — Door Open
Remote Start Aborted — Hood Open
Remote Start Aborted — Fuel Low
Remote Start Aborted — System Fault
The instrument cluster display message is

position.
TO ENTER REMOTE START MODE
Push and release the Remote Start button on
the key fob twice, within five seconds. The
parking lights will flash and the horn will chirp
twice (if programmed). In cold ambient
temperature conditions, the diesel vehicle may
delay crank up to 30 seconds for the Intake Air
Heater. Once the vehicle has started, the
engine will run for 15 minutes.
NOTE:
Crank may be delayed up to 75 seconds for
intake air heater operation at high altitudes,
and/or extreme cold.
The park lamps will turn on and remain on
during Remote Start mode.

For security, power window and power sunroof
operation (if equipped) are disabled when the
vehicle is in the Remote Start mode.

Additional features, such as windshield
wipers, will also not be available while the
vehicle is in the Remote Start mode.

The engine can be started two consecutive
times (two 15 minute cycles) with the key fob.
However, the ignition switch must be placed in
the ON/RUN position before you can repeat
the start sequence for a third cycle.

WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas
contains Carbon Monoxide (CO) which is
odorless and colorless. Carbon Monoxide is
poisonous and can cause serious injury or
death when inhaled.
Keep key fobs away from children. Opera -
tion of the Remote Start System, windows,
door locks or other controls could cause
serious injury or death.

(Continued)
The vehicle security alarm is designed to protect
your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the vehicle security
alarm will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this
occurs, disarm the vehicle security alarm.
If the vehicle security alarm is armed and the
battery becomes disconnected, the vehicle
security alarm will remain armed when the
battery is reconnected; the exterior lights will
flash, and the horn will sound. If this occurs,
disarm the vehicle security alarm.
REARMING OF THE SYSTEM
If something triggers the alarm, and no action is
taken to disarm it, the vehicle security alarm will
turn the horn off after 29 seconds, 5 seconds
between cycles, up to 8 cycles if the trigger
remains active and then the vehicle security
alarm will rearm itself.

WINDSHIELD WIPERS AND WASHERS
WINDSHIELD WIPERS
The wipers and washers are operated by a
switch in the multifunction lever, and can only
be operated with the ignition in the ACC or ON/
RUN position. Turn the end of the lever to select
the desired wiper speed.

Windshield Wiper/Washer Switch

Rotate the end of the lever upward, to the first
detent past the intermittent settings for
low-speed wiper operation. Rotate the end of the lever upward to the second detent past the
intermittent settings for high-speed wiper
operation.
Intermittent Wiper System
The intermittent feature of this system was
designed for use when weather conditions
make a single wiping cycle, with a variable
pause between cycles, desirable. For maximum
delay between cycles, rotate the control knob
upward to the first detent.
The delay interval decreases as you rotate the
knob until it enters the low continual speed
position. The delay can be regulated from a
maximum of about 18 seconds between cycles,
to a cycle every one second. The delay intervals
will double in duration when the vehicle speed
is 10 mph (16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer
knob, located on the end of the multifunction
lever, inward to the second detent. Washer fluid
will be sprayed and the wiper will operate for
two to three cycles after the washer knob is
released from this position.
If the washer knob is depressed while in the
delay range, the wiper will operate for several
seconds after the washer knob is released. It
will then resume the intermittent interval
previously selected. If the washer knob is
pushed while in the off position, the wiper will
turn on and cycle approximately three times
after the wash knob is released.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers.
WARNING!
Sudden loss of visibility through the
windshield could lead to a collision. You might
not see other vehicles or other obstacles. To
avoid sudden icing of the windshield during
freezing weather, warm the windshield with
the defroster before and during windshield
washer use.

one-half second. The sunroof and sunshade will
open automatically and stop when the full open
position is reached. This is called “Express
Open.” During Express Open operation, any
other actuation of the sunroof switch will stop
the sunroof.
Manual Mode
To open the sunroof, push and hold the switch
rearward. The sunroof will move rearward and
automatically stop at full open position. Any
release of the switch will stop the movement.

WARNING!
Never leave children unattended in a
vehicle, or with access to an unlocked
vehicle. Never leave the key fob in or near
the vehicle, or in a location accessible to
children. Do not leave the ignition of a
vehicle equipped with Keyless Enter-N-Go
in the ACC or ON/RUN mode. Occupants,
particularly unattended children, can
become entrapped by the power sunroof
while operating the power sunroof switch.
Such entrapment may result in serious
injury or death.
In a collision, there is a greater risk of being
thrown from a vehicle with an open sunroof.
You could also be seriously injured or killed.
Always fasten your seat belt properly and
make sure all passengers are also properly
secured.
Do not allow small children to operate the
sunroof. Never allow your fingers, other
body parts, or any object, to project through
the sunroof opening. Injury may result.

works when the ignition is in the ON/RUN, ACC,
or OFF position.

When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories connected
to the outlet(s) should be removed or turned off
when the vehicle is not in use to protect the
battery against discharge.
CAUTION!
Do not exceed the maximum power of
160 Watts (13 Amps) at 12 Volts. If the
160 Watts (13 Amps) power rating is
exceeded, the fuse protecting the system
will need to be replaced.

Power outlets are designed for accessory
plugs only. Do not insert any other object in
the power outlets as this will damage the
outlet and blow the fuse. Improper use of the
power outlet can cause damage not covered
by your New Vehicle Limited Warranty.

WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the
vehicle's battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.), will
discharge the battery even more quickly.
Only use these intermittently and with
greater caution.
After the use of high power draw accesso -
ries, or long periods of the vehicle not being
started (with accessories still plugged in),
the vehicle must be driven a sufficient
length of time to allow the generator to
recharge the vehicle's battery.
