Programming Transmitters to
the Vehicle
Only RKE transmitters
programmed to this 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 this
vehicle, all remaining transmitters
must also be reprogrammed.
Any lost or stolen transmitters
will no longer work once the new
transmitter is programmed. Each
vehicle can have up to four
transmitters programmed to it.
Battery Replacement
The battery in the transmitter is
weak and should be changed if it
does not work at the normal range
in any location.
Notice:When replacing the
battery, do not touch any of the
circuitry on the transmitter. Static
from your body could damage the
transmitter. To replace the battery:
1. Separate the transmitter with a
flat, thin object inserted into the
notch on the side.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery. Replace with a CR2032 or equivalent
battery.
4. Snap the transmitter back together.
Door Locks
{WARNING
Unlocked doors can be
dangerous.
.Passengers, especially
children, can easily open the
doors and fall out of a moving
vehicle. When a door is
locked, the handle will not
open it. The chance of being
thrown out of the vehicle in
a crash is increased if the
doors are not locked. So, all
passengers should wear
safety belts properly and the
doors should be locked
whenever the vehicle is
driven.

The seats have manual reclining
seatbacks. The lever used to
operate them is located on the
outboard side of the seats.
To recline the seatback:
1. Lift the recline lever and movethe seatback to the desired
position, then release the lever
to lock the seatback in place.
2. Push and pull on the seatback to make sure it is locked. To return the seatback to an upright
position:
1. Lift the lever fully without
applying pressure to the
seatback.
2. Push and pull on the seatback to make sure it is locked.
Do not have a seatback reclined
when the vehicle is moving.
{WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. In a crash, you could
go into it, receiving neck or other
injuries.
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen. The
belt forces would be there, not at
your pelvic bones. This could
cause serious internal injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.

3-6 Seats and Restraints
Heated Front Seats
{WARNING
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns
even at low temperatures.
To reduce the risk of burns,
people with such a condition
should use care when using
the seat heater, especially for
long periods of time. Do not
place anything on the seat that
insulates against heat, such as
a blanket, cushion, cover or
similar item. This may cause
the seat heater to overheat.
An overheated seat heater may
cause a burn or may damage
the seat.This feature heats the cushion and
seatbacks.
On vehicles with this feature the
controls are located on the outboard
sides of the front seats.
Press the top of the switch to
turn the heat to the high setting.
Press the bottom of the switch to
turn the heat to the low setting.
Put the switch in the center position
to turn the heat off.
The ignition must be on for the
heated seat feature to work. The
seat will heat to the last setting if the
ignition has been turned off and
then turned back on.
For the heated seat feature to work
on the passenger seat the safety
belt must be fastened.
