Manual Liftgate Operation
{WARNING
Exhaust gases can enter the
vehicle if it is driven with the
liftgate, trunk/hatch open, or
with any objects that pass
through the seal between the
body and the trunk/hatch or
liftgate. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled.
It can cause unconsciousness
and even death.
If the vehicle must be driven with
the liftgate, or trunk/hatch open:
.Close all of the windows.
.Fully open the air outlets
on or under the instrument
panel.(Continued)
WARNING (Continued)
.Adjust the Climate Control
system to a setting that
brings in only outside air
and set the fan speed to the
highest setting. See Climate
Control System in the Index.
.If the vehicle is equipped with
a power liftgate, disable the
power liftgate function.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
To unlock the liftgate, use the
power door lock switch or press
the door unlock button on the
RKE transmitter twice. See Remote
Keyless Entry (RKE) System
Operation on page 2‑3. To open the liftgate, press the
touchpad under the liftgate handle.
The vehicle must be in P (Park)
to open the liftgate. To close the
liftgate, use the pull cup or pull
strap as an aid.
The liftgate will not open if the
battery is disconnected or has low
voltage. The liftgate will resume
operation when the battery is
reconnected and charged.
If the battery is properly connected
and has adequate voltage, and the
liftgate still will not function, the
vehicle should be taken to a dealer
for service.

This vehicle has PASS-Key®III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key
®III+ is a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN, ACC/ACCESSORY
or START from the LOCK/OFF
position.
You do not have to manually arm or
disarm the system. The security light comes on if
there is a problem with arming
or disarming the theft-deterrent
system.
When the PASS-Key
®III+ system
senses an incorrect key, the vehicle
does not start. Anyone using a
trial-and-error method to start the
vehicle will be discouraged because
of the high number of electrical key
codes.
If the engine does not start and
the security light on the instrument
panel comes on when trying to start
the vehicle, there may be a problem
with your theft-deterrent system.
Turn the ignition off and try again.
If the engine still does not start,
and the key appears to be
undamaged, try another ignition
key and check the fuses. See Fuses
and Circuit Breakers on page 10‑32
for additional information. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who can service the PASS-Key
®III+
to have a new key made. In an
emergency, contact Roadside
Assistance. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10.
It is possible for the PASS-Key
®III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
to the vehicle. The following
procedure is for programming
additional keys only. If all the
currently programmed keys are
lost or do not operate, you must
see your dealer or a locksmith who
can service PASS-Key
®III+ to have
keys made and programmed to the
system.
See your dealer or a locksmith who

flashers by using the controls for
those features.
{WARNING
A crash severe enough to inflate
the airbags may have also
damaged important functions
in the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.In many crashes severe enough
to inflate the airbag, windshields
are broken by vehicle deformation.
Additional windshield breakage
may also occur from the right front
passenger airbag..Airbags are designed to inflate
only once. After an airbag
inflates, you will need some
new parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy on
page 13‑18 andEvent Data
Recorders on page 13‑18.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to
the warning lights and gauges
could prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working. Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

Instruments and Controls 5-13
Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper-resistant
odometer. If the vehicle needs a
new odometer installed, the new
one is set to the mileage of the old
odometer. If this is not possible, it is
set at zero and a label is put on the
driver door to show the old mileage
reading.
Tachometer
The tachometer displays the
engine speed in revolutions per
minute (rpm).
Fuel Gauge
MetricEnglish
When the ignition is on, the fuel
gauge shows how much fuel is
left in the tank.
An arrow in the fuel gauge indicates
the side of the vehicle the fuel door
is on.
The gauge will first indicate empty
before the vehicle is out of fuel,
the vehicle's fuel tank should be
filled soon.
When the fuel tank is low on fuel,
the FUEL LEVEL LOW message will
appear on the Driver Information Center (DIC). For more information
see
Fuel System Messages on
page 5‑41.
Here are some situations that may
occur with the fuel gauge. None of
these indicate a problem with the
fuel gauge..At the gas station, the fuel pump
shuts off before the gauge
reads full.
.It takes a little more or less fuel
to fill up than the fuel gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.The gauge goes back to empty
when the ignition is turned off.

5-14 Instruments and Controls
Engine Coolant
Temperature Gauge
MetricEnglish
This gauge shows the engine
coolant temperature. Under normal
driving conditions the gauge will
read approximately 100 °C (210°F)
or less. If the gauge pointer is
near 125 °C (260°F), the engine
is too hot.
It means that the engine coolant
has overheated. If the vehicle has
been operating under normal driving
conditions, pull off the road, stop the
vehicle and turn off the engine as
soon as possible.
See Engine Overheating on
page 10‑19 for more information.
Voltmeter Gauge
When the engine is not running, but
the ignition is turned on, this gauge
shows the battery's state of charge
in DC volts.
When the engine is running, this
gauge shows the condition of the
charging system. The vehicle's
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may fluctuate.
This is normal. Readings between
the low and high warning zones
indicate the normal operating range. Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
idling for an extended period.
If there is a problem with the battery
charging system, a SERVICE
BATTERY CHARGING SYSTEM
message will appear in the Driver
Information Center (DIC) and/or
the charging system light comes on.
See
Battery Voltage and Charging
Messages on page 5‑37 for more
information.
However, readings in either warning
zone may indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.
