To allow a rear door to be opened
from inside the vehicle, unlock the
child safety lock.This system helps to protect your
vehicle and valuables. The horn will
sound and the hazard warning lights
will blink continuously if any of the
following occur:
- A door is opened without using the
smart key.
- The liftgate is opened without using the smart key.
- The engine hood is opened.
The alarm continues for 30 seconds,
then the system resets. To turn off
the alarm, unlock the doors with the
smart key.
The Theft Alarm System automati-
cally sets 30 seconds after you lock
the doors and the liftgate. For the
system to activate, you must lock the
doors and the liftgate from outside
the vehicle with the smart key or by
pressing the button on the outside of
the door handles with the smart key
in your possession.
The hazard warning lights will blink
and the chime will sound once to
indicate the system is armed. Once the security system is set,
opening any door, the liftgate, or the
hood without using the smart key will
cause the alarm to activate.
The Theft Alarm System will not set if
the hood, the liftgate, or any door is
not fully closed. If the system will not
set, check the hood, the liftgate, or
the doors are fully closed.
Do not attempt to alter this system or
add other devices to it.
Information

sengers have left the vehicle. If the
remaining passenger leaves the
vehicle when the system is armed,
the alarm will be activated.

using the mechanical key and start
the vehicle by directly pressing the
Engine Start/Stop button with the
smart key.

There are some conditions that can
cause changes to the vehicle mag-
nets, such as installing a ski rack or
a CB antenna. Body repair work on
the vehicle can also cause changes
to the vehicle’s magnetic field. In
these situations, the compass will
need to be re-calibrated to quickly
correct these changes. If you need to recalibrate the com-
pass:
1. Press and hold the button for
more than 9 seconds. When the
compass memory is cleared a "C"
will appear in the display.
2. Drive the vehicle in 2 complete cir- cles at less than 5 mph (8 km/h).
Integrated HomeLink®Wireless
Control System
The HomeLink®Wireless Control
System can replace up to three
hand-held radio-frequency (RF)
transmitters with a single built-in
device. This innovative feature will
learn the radio frequency codes of
most current transmitters to operate
devices such as gate operators,
garage door openers, entry door
locks, security systems, even home
lighting. Both standard and rolling
code-equipped transmitters can be
programmed by following the out-
lined procedures.
Additional HomeLink
®information
can be found at: www.homelink.com
or by calling 1-800-355-3515.
Retain the original transmitter of the
RF device you are programming for
use in other vehicles as well as for
future HomeLink
®programming. It is
also suggested that upon the sale of
the vehicle, the programmed
HomeLink
®buttons be erased for
security purposes.

Closing the hood
1. Before closing the hood, check thefollowing:
ment must be correctly installed.
bustible material must be
removed from the engine com-
partment.
2. Lower the hood halfway (lifted approximately 12 inches (30 cm)
from the closed position) and push
down to securely lock in place.
Then double check to be sure the
hood is secure. If the hood can be
raised slightly, it is not securely
locked. Open it again and close it
with more force.

warning light or message dis-
played on the instrument clus-
ter. Driving with the hood
opened may cause a total loss
of visibility, which might
result in an accident.
Do not move the vehicle with
the hood in the raised posi-
tion, as vision is obstructed,
which might result in an acci-
dent, and the hood could fall
or be damaged.

3. Pull the fuel filler door (1) out tofully open.
4. To remove the fuel tank cap (2), turn it counterclockwise. You may
hear a hissing noise as the pres-
sure inside the tank equalizes.
5. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn it clockwise until it "clicks" one time.
2. Close the fuel filler door until it is latched securely.
i
Gasoline is highly flammable
and explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refueling, note the
location of the Emergency
Gasoline Shut-Off, if available,
at the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
(Continued)
WARNING
(Continued)
Do not use cellular phones
while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by
touching, rubbing or sliding
against any item or fabric
capable of producing static
electricity. Static electricity
discharge can ignite fuel
vapors causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other gasoline
source, with your bare hand.(Continued)
