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. Fully functional daytime running
lamps are required on all vehicles rst sold in Canada.
The DRL system will make both front turn signal lamps
turn on when the following conditions are met:
The ignition is on.
The exterior lamp control is turned to AUTO.
In addition, Canadian vehicles DRL will also turn
on if you have turned on your parking lamps.
The light sensor detects daytime light.
The shift lever is not in PARK (P).
While the DRL system is on, the taillamps, sidemarker
lamps, and instrument panel lights will not be illuminated.
The DRL system will be off any time your vehicle is in
PARK (P). The DRL system on U.S. vehicles can
also be turned off by using the Off/On switch for one
ignition cycle.
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 system
will turn on your headlamps at the normal brightness
along with other lamps such as the taillamps, sidemarker,
parking lamps, instrument panel lights, and interior
switch backlighting.
Your vehicle is equipped with a light sensor on the top of
the instrument panel that inputs to the ACC, so be 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.
There is a delay in the transition between the daytime
and nighttime operation of the automatic lamp control
system so that driving under bridges or bright overhead
street lights does not affect the system. The automatic
lamp control system will only be affected when the light
sensor sees a change in lighting lasting longer than
this delay.
If you start your vehicle in a dark garage, the automatic
lamp system will come on immediately. Once you leave
the garage, it will take about one minute for the automatic
lamp system to change to DRL if it is light outside.

Use the steps below to place the entire system in
automatic mode:
1. Place the fan knob and the mode knob to the
AUTO position.
The display will now show the current set
temperature. When auto is selected, the air
conditioning operation and air inlet will be
automatically controlled. The air conditioning
compressor will run when the outside temperature
is over about 40°F (4°C). The air inlet will normally
be set to outside air. If it’s hot outside, the air
inlet may automatically switch to recirculate inside
air to help quickly cool down your vehicle.
2. Set the temperature.
To nd your comfort setting, start with an initial
temperature setting and allow about 20 minutes for
the system to regulate. Press the up or down arrow
temperature buttons to adjust the temperature
setting as necessary. If you choose the temperature
setting of 60°F (15°C) the system will remain at
the maximum cooling setting. If you choose the
temperature setting of 90°F (32°C) the system will
remain at the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to heat
or cool any faster.Be careful not to cover the sensor located on the
top of the instrument panel near the windshield.
This sensor regulates air temperature based on sun
load, and also turns on your headlamps.
Also be careful not to cover the sensor grille on
the lower right side of the climate control faceplate.
This senses the inside vehicle temperature
needed for proper regulation.
To avoid blowing cold air at start-up in cold weather,
the system will delay turning on the fan until
warm air is available. The length of delay depends
on the engine coolant temperature. Turning the
fan knob will override this delay and change the
fan to a selected speed.
If your vehicle has the remote start feature, the climate
control display will initially show “AS” in place of the
temperature to indicate the remote start has been
activated. The system will automatically regulate the
temperature.

Safety Belt Reminder Light
When the key is turned to ON, a chime will come
on for several seconds to remind people to fasten their
safety belts, unless the driver’s safety belt is already
buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will ash for
several more.
If the driver’s belt is already buckled, neither the
chime nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensor, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, seeAir Bag Systems on page 1-52.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should
go out. This means the
system is ready.
If the air bag readiness light stays on after you start
the vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
