halves of the remote entry
transmitter near the key ring. DO
NOT TAKE THE RUBBER COVER
AND CIRCUIT BOARD OFF THE
FRONT HOUSING OF THE
REMOTE ENTRY TRANSMITTER.
2. Do not wipe off any grease on the
battery terminals on the back
surface of the circuit board.
3. Remove the old battery.Note:Please refer to local regulations when
disposing of transmitter batteries.
4. Insert the new battery. Refer to the diagram inside the remote entry
transmitter for the correct orientation of the battery. Press the battery

Replacing lost transmitters
If a remote transmitter has been lost and you would like to remove it
from the vehicle’s memory, or you would like to purchase additional
remote transmitters and have them programmed to your vehicle:
•Takeallyour vehicle’s transmitters to your authorized dealer for
programming, or
•Perform the programming procedure yourself.

Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
If the tire label shows different tire pressures for the front and
rear tires and the vehicle is equipped with TPMS (tire pressure
monitoring system), then the settings for the TPMS sensors need to be
updated. Always perform the TPMS reset procedure after tire rotation.
If the system is not reset, it may not provide a low tire pressure
warning when necessary. See the TPMS reset procedure in this
chapter.

Tire rotation using the
recommended sequence
(front tires at top of diagram)
Sensor position following tire
rotation
Sensor 1: 50 psi
Sensor 2: 50 psi
Sensor 3: 80 psi
Sensor 4: 80 psi
Pressure adjustment without the
required TPMS reset procedure
Sensor 1: 80 psi
Sensor 2: 80 psi
Sensor 3: 50 psi
Sensor 4: 50 psi
In this situation, the TPMS warning
light will come on.
If the TPMS reset procedure is not performed after tire rotation and air
pressure adjustment, the TPMS telltale may illuminate for a false low tire
pressure condition.
