Replacing the battery
The remote entry transmitter uses one coin type three-volt lithium
battery CR2032 or equivalent. The typical operating range for your
remote entry transmitter is approximately 10 meters (33 feet). A
decrease in the operating range could be caused by:
• weather conditions,
• nearby radio towers,
• structures around the vehicle and
• other vehicles parked next to the vehicle.
To replace the battery:
1. Twist a thin coin between the two
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.
4. Insert the new battery. Refer to the diagram inside the remote entry
transmitter for the correct orientation of the battery. Press the battery
down to ensure that the battery is fully seated in the battery housing
cavity.
5. Snap the two halves back together.
Note: Replacement of the battery will not cause the remote transmitter
to become deprogrammed from your vehicle. The remote transmitter
should operate normally after battery replacement.

Sometimes irregular tire wear can be corrected by rotating the tires.
Note: If your tires show uneven wear ask a qualified technician at a
reputable repair facility to check for and correct any wheel misalignment,
tire imbalance or mechanical problem involved before tire rotation.
Tire wear
Measure and inspect the tire tread on all your tires periodically.
Advanced and unusual tire wear can reduce the ability of tread to grip
the road in adverse (wet, snowy, etc.) conditions. Visually check your
tires for uneven wear, looking for high and low areas or unusually
smooth areas. Also check for signs of tire damage.
When the tread is worn down to 4
mm (1/16th of an inch), tires must
be replaced to prevent your vehicle
from skidding and hydroplaning.
Built-in treadwear indicators, or
“ wear bars ” , which look like narrow
strips of smooth rubber across the
tread will appear on the tire when
