Remote Vehicle Start
This vehicle may have a remote starting feature that
starts the engine from outside of the vehicle. It may also
start the vehicle’s automatic climate control system.
When the remote start system is active, the climate
control system heats and cools the inside of the vehicle
according to the previous settings of the system
before turning the vehicle off. The windshield defroster
or rear window defogger turn on if it is cold outside.
If the vehicle has heated seats, they also turn on. See
Heated and Ventilated Seats on page 1-6for additional
information. Normal operation of the climate control
system returns after the ignition is turned to ON/RUN.
SeeDual Climate Control System on page 3-24.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
Do not use the remote start feature if the vehicle is low
on fuel. The vehicle may run out of fuel.
If this vehicle has the remote start feature, the RKE
transmitter functions have an increased range of
operation. However, the range may be less while
the vehicle is running.There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-6orKeyless Access
System on page 2-9for additional information.
/(Remote Start):Press and release the lock button
and then press and hold this button to use the remote
start feature.
To start the vehicle using the remote start feature:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the transmitter’s
remote start button until the turn signal lights ash or
if the vehicle’s lights are not visible, press and hold
the remote start button for at least four seconds.
The vehicle’s doors lock. Pressing the remote start
button again after the vehicle has started turns off
the ignition.
When the vehicle starts, the parking lamps turn on
and remain on while the vehicle is running.
3. If it is the rst remote start since the vehicle has
been driven, repeat these steps, while the engine is
still running, to extend the engine running time by
10 minutes. Remote start can be extended one time.
After entering the vehicle during a remote start, press
the brake pedal and turn the ignition to ON/RUN to drive
the vehicle.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines for the rst 500 miles
(805 km):
Do not drive at any one constant speed, fast
or slow.
Do not exceed 70 mph (113 km/h).
Do not make full-throttle starts; also refrain
from using the full throttle while driving.
Avoid downshifting to brake or slow the vehicle.
If these procedures are not followed, the engine,
axle, or other parts could be damaged.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake linings
are not yet broken in. Hard stops with new linings
can mean premature wear and earlier replacement.
Follow this break-in guideline every time you get
new linings.Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-30for the trailer towing capabilities
of your vehicle and more information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions (Key Access)
The key can be turned to four different positions.
To shift out of PARK (P), ignition must be in the
ON/RUN or ACC/ACCESSORY and the regular brake
pedal must be applied.
2-32

Ignition Positions (Keyless Access)
You can turn the ignition control knob to four different
positions.
To shift out of PARK (P), ignition must be in the
ON/RUN or ACC/ACCESSORY and the regular brake
pedal must be applied.
Using a tool to force the ignition control knob from its
cylinder could damage it.
Make sure the keyless access transmitter is inside the
vehicle when trying to turn the ignition control knob.A (LOCK/OFF):The ignition control knob cannot
be removed from the vehicle. The keyless access
transmitter must be inside the vehicle to start the engine.
This position locks the ignition and shifter on automatic
transmission vehicles, and the ignition and steering
wheel on manual transmission vehicles.
B (ACC/ACCESSORY):This position allows you to use
things like the radio and the windshield wipers when
the engine is off. This position will allow you to turn off
the engine.
C (ON/RUN):This position is for driving. It is the
position the ignition switch returns to after the engine
starts, and the control knob is released.
If you need to shift the transmission out of PARK (P),
the ignition control knob has to be in ACC/ACCESSORY
or ON/RUN.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the engine
off. You may not be able to start your vehicle if the battery
is allowed to drain for an extended period of time.
D (START):This position starts the engine.
2-34

Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
Sunroof (if equipped)
Power to the audio system will work up to 10 minutes or
until the driver’s door is opened. Power to the windows
or sunroof will work up to 10 minutes or until any
door is opened. For an additional 10 minutes of
operation, close all the doors and turn the key to
ON/RUN and then back to LOCK/OFF.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to PARK (P) or NEUTRAL (N).
The engine will not start in any other position -- this
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.If your vehicle has the keyless access system, put your
foot on the brake pedal and turn the ignition control
knob to the START position. When the engine begins
cranking, let go of the ignition control knob, it will return
to the ON/RUN position.
If the transmitter is not in the vehicle or something is
interfering with the transmitter, the Driver Information
Center (DIC) will display Electronic Key Not Detected.
SeeDIC Warnings and Messages on page 3-56for
more information.
If the battery in the keyless access transmitter needs
replacing, the DIC displays Replace Battery In Remote
Key. The vehicle can still be driven. See “Battery
Replacement” underKeyless Access System Operation
on page 2-10for more information.
Notice:Do not try to shift to P (Park) if your
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when your
vehicle is stopped.
2-35

Manual Transmission
The shift lever should be in neutral position and the
parking brake engaged. Hold the clutch pedal down
to the oor and start the engine. Your vehicle will
not start if the clutch pedal is not all the way down.
That is a safety feature.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. If your vehicle has the keyless
access system, make sure there is a keyless access
transmitter in the vehicle. When the engine starts,
let go of the ignition. The idle speed will go down
as your engine gets warm. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START for many seconds, cranking will be stopped
after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to ACC/ACCESSORY or LOCK/OFF.Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START
for up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms
up and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.
