The RKE transmitter with the remote start button,
provides an increased range of operation. However, the
range may be less while the vehicle is running. As a
result, you may need to be closer to your vehicle to turn
it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-4for additional
information.
/(Remote Start):This button will be on the RKE
transmitter if you have remote start.
To start the vehicle:
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. If you
cannot see the vehicle’s lights, press and hold the
remote start button for at least four seconds. The
vehicle’s doors will lock. Pressing the remote start
button again, after the vehicle has started, will shut
the vehicle off.
When the vehicle starts, the parking lamps will 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 time by 10 minutes for
the engine to continue to run. Remote start can
be extended one time.
After entering the vehicle during a remote start, insert
and turn the key to the ON/RUN position to drive
the vehicle.
If the vehicle is left running it will automatically shut off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The vehicle can be started using the remote start
feature two separate times between driving sequences.
The engine will run for 10 minutes after each remote
start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote start time
frame, and before the engine stops.

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:
If you have all-wheel drive, keep your speed at
55 mph (88 km/h) or less for the rst 500 miles
(805 km).
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
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 breaking-in guideline
every time you get new brake 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.

Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the key in
the ignition and park your vehicle, a chime will sound
when you open the driver’s door. Always remember to
remove your key from the ignition and take it with you.
This will lock your ignition and transmission. Also, always
remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be able
to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the ignition key is turned off:
Audio System
Power Windows
Sunroof (if equipped)Power to the windows and sunroof will work up to
10 minutes or until a door is opened.
The radio continues to work for 10 minutes or until the
driver’s 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.
All these features will work when the key is in the
ON/RUN or ACC/ACCESSORY positions.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N). Your
engine will not start in any other position – this is a safety
feature. To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your vehicle
is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
2-27

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts, let go
of the key. 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 the ACC/ACCESSORY or LOCK/OFF
position.
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 your 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, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brake rst and then press the
shift lever button before you can shift from PARK (P)
when the ignition key is in ON. If you cannot shift out of
PARK (P), ease pressure on the shift lever, then
push the shift lever all the way into PARK (P) as you
maintain brake application. Then press the shift
lever button and move the shift lever into another gear.
SeeShifting Out of PARK (P) on page 2-37.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-20.NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.

8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let
go. The wipers stop after one wipe. Hold the band
on mist longer, for more wipe cycles.
9(Off):To stop the wipers, move the band to off.
6(Delay):Turn the band to adjust the delay time.
The delay between wiping cycles becomes shorter
as the band is moved to the top of the lever. This can
be very useful in light rain or snow.
1 (Low Speed):Turn the band away from you to
the rst solid band past the delay settings, for steady
wiping at low speed.
2 (High Speed):Turn the band further, to the second
solid band past the delay settings, for high-speed wiping.
Windshield Washer
J(Washer Fluid):Press the button located at the
end of the turn signal/multifunction lever, to spray
washer uid on the windshield. The wipers clear the
windshield and either stop or return to the preset speed.
The ignition key must be in ACCESSORY or ON for
this to work. SeeWindshield Washer Fluid on page 5-34
Windshield Washer Fluid.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
WASHER FLUID LOW ADD FLUID is displayed on the
Driver Information Center (DIC) when the washer uid is
low. SeeDIC Warnings and Messages on page 3-66.
