Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about four years.
You can tell the battery is weak if the transmitter
will not work at the normal range in any location.
If you have to get close to your vehicle before
the transmitter works, it is probably time to change
the battery.
The REPLACE BATTERY IN REMOTE KEY
message in the vehicle’s DIC will display if the
RKE transmitter battery is low. See “REPLACE
BATTERY IN REMOTE KEY” underDIC Warnings
and Messages on page 254for additional
information.
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.To replace the battery in the RKE transmitter do
the following:
1. Use a at object with a thin edge into the
notch, located below the trunk release
button, and separate the bottom half from the
top half of the transmitter.
2. Remove the old battery, but do not use a
metal object to do this.

Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system it is designed to help you
park while in Reverse (R). It operates only at
speeds less than 5 mph (8 km/h). URPA helps
make parking easier and helps you avoid colliding
with objects such as parked vehicles. The URPA
system detects objects that are close to the rear of
the vehicle which are at least 10 inches (25.4 cm)
off the ground and below hood or trunk level.
The system detects objects up to 8 feet (2.5 m)
behind your vehicle. URPA determines how close
these objects are from your bumper within this area.
Ultrasonic sensors on the rear bumper are used to
detect the distance to the object.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully
before backing up. The system does not
CAUTION: (Continued)
CAUTION: (Continued)
operate above speeds of 5 mph (8 km/h).
The system does not detect objects more
than 8 feet (2.5 meters) behind the vehicle.
This detection distance limit may be
reduced during warm weather or high
humidity. Also, the system does not
detect objects that are below your
bumper, underneath your vehicle, or
some objects very close to the vehicle.
The system is not designed to detect
children, pedestrians, bicyclists, or pets.
So, unless you check carefully behind
your vehicle while you are backing up,
they could be injured or killed.
Whether or not you are using rear park
assist, always check carefully behind your
vehicle before backing up and then watch
closely as you do.

How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an
object is detected a single beep will sound. If an
object is detected at a REVERSE (R) speed
between 0 mph (0 km/h) and 5 mph (8 km/h), the
following describes what will occur based on your
distance to a detected object located behind the
vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will come on.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be on.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/
amber/red) will be on.
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will be on and
ashing.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARKING
ASSIST OFF will be displayed on the DIC and a
red light will be shown on the rear URPA display
when the shift lever is moved into REVERSE (R).
This occurs under the following conditions:
The driver disables the system. SeeDIC
Operation and Displays (With DIC Buttons)
on page 244orDIC Operation and Displays
(Without DIC Buttons) on page 251.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your
trunk during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next
drive, the system will return to normal operation
unless an object is detected when the vehicle is
shifted into REVERSE (R). If this occurs, URPA
assumes the object is still attached, so you will
have to wait until the vehicle is driven forward
above 15 mph (25 km/h) before URPA will
return to normal operation.

Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it
is in your vehicle. Static electricity
discharge from the container can ignite the
gasoline vapor. You can be badly burned
and your vehicle damaged if this occurs.
To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup
bed, or on any surface other than the
ground.
Bring the ll nozzle in contact with the
inside of the ll opening before
operating the nozzle. Contact should
be maintained until the lling is
complete.
Do not smoke while pumping gasoline.
Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools
away from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.
