Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle’s
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.{CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby does not
weigh much — until a crash. During a crash a
baby will become so heavy it is not possible to
hold it. For example, in a crash at only 25 mph
(40 km/h), a 12 lb (5.5 kg) baby will suddenly
become a 240 lb (110 kg) force on a person’s
arms. A baby should be secured in an
appropriate restraint.

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three 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.
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.
1. Insert a at object, such as a coin, into the slot on
the side of the transmitter and twist it to separate
the halves.
2. Gently pry the battery out of the transmitter. Do not
use the metal anges to pop out the battery.
3. Replace the battery.
4. Reassemble the transmitter. Make sure the halves
are snapped together tightly so water will not get in.
5. Press and hold the lock and unlock buttons
for seven seconds to synchronize the transmitter.
6. Check the transmitter operation.

Automatic Door Lock
All of the doors will lock automatically when you move
the shift lever out of PARK (P). This feature cannot
be disabled.
If someone needs to get out of the vehicle while it is not
in PARK (P), shift into PARK (P), or, have that person
use the manual lever or the power door lock switch.
When the door is closed again, it will lock when
the vehicle exceeds 5 mph (8 km/h).
With automatic door locks, you can lock or unlock the
doors at any time, either manually or by using the power
door lock switches.
Programmable Automatic Door
Unlock
Your vehicle was programmed so that all doors will
unlock automatically when the shift lever is moved into
PARK (P).
To change the way the automatic door unlocking
operates, seeDIC Vehicle Personalization (Uplevel
Only) on page 3-72.
Lockout Protection
The lockout protection feature makes it more difficult to
lock the key in the vehicle. If the driver’s door is
open while the key is in the ignition, the door cannot be
locked with the power door lock switch.
This feature cannot guarantee that you will never be
locked out of the vehicle. If the key is not left in
the ignition, or, if the manual door lock is used, the key
could still be locked inside the vehicle. Always
remember to take the key with you.
Dual Sliding Doors
To open either sliding door from outside the vehicle, pull
the handle out and then pull the door toward the rear.
If you slide the door all the way back, the door will rest in
a detent position.
To move the door forward, you must rst pull the door
past the open detent position.
The driver’s side sliding door is designed to open only a
little if the fuel door is open. If this ever happens, do not
try to force the sliding door. Just close the driver’s side
sliding door. Then when the fuel ller door is closed, the
driver’s side sliding door can be opened normally.

When it is dark enough outside, the exterior lamps will
come on automatically. When it is bright enough
outside, the exterior lamps will turn off and the DRL will
turn on. Of course, you may still turn on the headlamps
any time you need to.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
30 seconds for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument Panel
Brightness on page 3-17.
To idle your vehicle with the DRL and automatic
headlamps off, toggle the exterior lamp control to off
after starting the vehicle.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Instrument Panel Brightness
The knob to adjust the
instrument panel
brightness is located in the
center of the interior
lamp controls.
Turn the knob clockwise to brighten the lights and
counterclockwise to dim them.

Average Speed
Press the information button until AVERAGE SPEED
displays. This mode shows the average speed of the
vehicle in miles per hour (mph) or kilometers per hour
(km/h). This average is calculated based on the various
vehicle speed recorded since the last reset of this value.
To reset the value, press the information button to display
AVERAGE SPEED, then press and hold the set/reset
button. The display will return to zero.
Fuel Range
Press the information button until FUEL RANGE
displays. This mode shows the approximate number of
remaining miles or kilometers the vehicle can be
driven without refueling.
Fuel range is based on several factors, including
distance travelled, fuel used, fuel capacity, etc. This
estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this mode may read one number, but if the vehicle
is driven on a freeway, the number may change even
though the same amount of fuel is in the fuel tank. This
is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
Fuel range cannot be reset.If your vehicle is low on fuel, FUEL RANGE LOW will
display followed by the LOW FUEL message. See “LOW
FUEL” underDIC Warnings and Messages on
page 3-56for more information.
Average Fuel Economy
Press the information button until AVG ECONOMY
displays. This mode shows the approximate average
miles per gallon (mpg) or liters per 100 kilometers
(L/100 km). This number is calculated based on the
number of mpg (L/100 km) recorded since the last time
this menu item was reset. To reset AVG ECONOMY,
press and hold the set/reset button. The display
will return to zero.
Instantaneous Fuel Economy
Press the information button until INST ECONOMY
displays. This mode shows the current fuel economy at
a particular moment and will change frequently as
driving conditions change. This mode shows the
instantaneous fuel economy in miles per gallon (mpg) or
liters per 100 kilometers (L/100 km). Unlike average
fuel economy, this screen cannot be reset.

Battery
Press the information button until BATTERY displays.
This mode shows the current battery voltage.
If there is a problem with the battery charging system, a
DIC message will display. SeeDIC Warnings and
Messages on page 3-56for more information.
Your vehicle’s charging system regulates voltage based
on the state of the battery. The battery voltage may
uctuate when viewing this information on the DIC. This
is normal.
Oil Life
Press the information button until OIL LIFE displays.
This mode shows an estimate of the oil’s remaining
useful life. If you see OIL LIFE 99% on the display, that
means 99% of the current oil life remains. The engine
oil life system will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the LOW OIL
PRESSURE message will appear on the display. You
should change your oil as soon as possible. SeeEngine
Oil on page 5-15. In addition to the engine oil life
system monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4for
more information.Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed. It
cannot be reset accurately until the next oil change.
To reset the engine oil life system, seeEngine Oil Life
System on page 5-18. The display will show 100%
when the system is reset.
