Head Restraints
The head restraints on both the front and rear seats are
adjustable. Press the button at the base of the head
restraint to lower it. Pull up on the restraint to raise it.
Adjust the head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
Seatback Latches
The front seatbacks fold
forward to let people get
into the back seat.
To fold a front seatback, lift the lever located near the
top of either front seat to tilt the seatback forward. Press
and hold the button located below the seatback lever
to move the entire seat forward all the way.
A weight sensor has been built into the front seats.
The seat will not move forward if there is more than
27 lbs (12 kg) on the seat sensor.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset.
The DRL system will make your low-beam headlamps
come on at a reduced brightness when the following
conditions are met:
•The ignition is on.
•The exterior lamp control is turned to AUTO and
the light sensor detects daytime light.
•The exterior lamp control is turned to the off
position.
•The parking brake is released.
•For vehicles with automatic transmissions, the shift
lever is not in PARK (P).
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps, and instrument panel lights will not
be illuminated unless you have turned the exterior lamps
control to the parking lamp or headlamp position.
The DRL system will remain off any time your vehicle is
in PARK (P) or the parking brake is engaged the first
time the ignition is turned on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Automatic Headlamp System
When it is dark enough outside, your Automatic
Headlamp System will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps, and the
instrument panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the
top of the instrument panel under the defroster
grill. Make sure it is not covered, which will cause the
system to be on whenever the ignition is on.
The system may also be on when driving through a
parking garage, heavy overcast weather, or a tunnel.
This is normal.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately.
As with any vehicle, you should turn on the regular
headlamps when you need them.
The headlamps can be set to come on at different
levels. The sensitivity can be adjusted to Early, Normal,
or Late. SeeVehicle Personalization on page 2-30.
Leaving the headlamps and parking lamps on when the
engine is not running will eventually drain the battery.

Airbag Readiness Light
There is an airbag
readiness light on the
instrument panel which
shows the airbag symbol.
This light will come on when you start your vehicle, and
it will flash for a few seconds. Then the light should
go out. This means the system is ready.
The system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag
sensors, the airbag modules, the wiring and the
diagnostic module. SeeAirbag System on page 1-44for
more information.If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your
airbag system may not work properly. Have your vehicle
serviced right away. The light comes on after an
accident where the airbags were activated.
{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the airbag readiness light
stays on after you start your vehicle.
