Programming Transmitters to the Vehicle
Only RKE transmitters programmed to the
vehicle will work. If a transmitter is lost or
stolen, a replacement can be purchased and
programmed through your dealer. When the
replacement transmitter is programmed to
the vehicle, all remaining transmitters must
also be programmed. Any lost or stolen
transmitters no longer work once the new
transmitter is programmed. Each vehicle can
have up to four transmitters programmed
to it.
Battery Replacement
{Warning
Never allow children to play with the RKE
transmitter. The transmitter contains a
small battery, which can be a choking
hazard. If swallowed, internal burns can
occur, resulting in severe injury or death.
Seek medical attention immediately if a
battery is swallowed.
{Warning
To avoid personal injury, do not touch
metal surfaces on the RKE transmitter
when it has been exposed to extreme
heat. These surfaces can be hot to the
touch at temperatures above 59 °C
(138 °F).
Caution
When replacing the battery, do not touch
any of the circuitry on the transmitter.
Static from your body could damage the
transmitter.
Caution
Always replace the battery with the
correct type. Replacing the battery with
an incorrect type could potentially create
a risk of battery explosion. Dispose of
used batteries according to instructions
and local laws. Do not attempt to burn,
crush, or cut the used battery, and avoid
exposing the battery to environments
with extremely low air pressures or high
temperatures.Replace the battery if the DIC displays
REPLACE BATTERY IN REMOTE KEY.
To replace the battery:
1. Separate the transmitter with a flat, thin object, such as a flat head screwdriver.
.Carefully insert the tool into the
notch located along the parting line
of the transmitter. Do not insert the
tool too far. Stop as soon as
resistance is felt.
.Twist the tool until the transmitter is
separated.
2. Remove the old battery. Do not use a metal object.

feature. This feature allows you to start the
engine from outside the vehicle. It may also
start the vehicle's heating or air conditioning
systems. See Climate Control Systems 0119.
Laws in some local 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.

136 Driving and Operating
To turn off the vehicle:1. Make sure that the vehicle is stopped.
2. Shift to P (Park).
3. Continue to hold the brake pedal, then set the parking brake. See Parking Brake
0 146.
4. Push the key all the way in toward the steering column (1), then turn the key to

Retained Accessory Power (RAP) will remain
active. See Retained Accessory Power (RAP)
0 138.
A warning chime will sound when the driver
door is opened and the key is in the
ignition.
If equipped with a locking steering column,
the steering can bind with the front wheels
turned off center, which may prevent key
rotation out of LOCK/OFF. If this happens,
move the steering wheel from right to left
while turning the key to ACC/ACCESSORY.
If this does not work, then the vehicle needs
service.{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
airbags. While driving, turn off the
vehicle only in an emergency.
In an emergency, if the vehicle cannot be
pulled over and must be turned off while
driving: 1. Push the key all the way in toward the steering column, then turn the key to
ACC/ACCESSORY.
2. Brake using firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
3. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
Continue braking and steer the vehicle to
a safe location.
4. Come to a complete stop.
5. Shift to P (Park).

your hand.
1 (ACC/ACCESSORY) : This position allows
features such as the infotainment system to
operate while the vehicle is off. It also

with a locking steering column. Use this
position if the vehicle must be pushed or
towed. See Retained Accessory Power (RAP)
0 138.
From ON/RUN, push the key all the way in
toward the steering column, then turn the
key to ACC/ACCESSORY.
If the key is left in ACC/ACCESSORY with the

be used for service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may be
required for emission inspection purposes.
The switch stays in this position when the
engine is running. The transmission is also
unlocked in this position.
If the key is left in ON/RUN with the engine

N (Neutral). The engine will not start in any
other position. To restart the engine when
the vehicle is already moving, use
N (Neutral) only.
Caution
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
See Add-On Electrical Equipment 0176.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could
damage the transmission. Shift to P (Park)
only when the vehicle is stopped.
Caution
If the steering wheel is turned until it
reaches the end of its travel, and is held
in that position while starting the vehicle,
damage may occur to the hydraulic
power steering system and there may be
loss of power steering assist.
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.
When the low fuel warning light is on
and the FUEL LEVEL LOW message is
displayed in the Driver Information
Center (DIC), the Computer-Controlled
Cranking System is disabled to prevent
possible vehicle component damage.
When this happens, hold the ignition
switch in the START position to continue
engine cranking.
