Headlamps on Reminder
A warning chime will sound if the vehicle’s ignition
is off and the driver’s door is opened when the
exterior lamp control is left on in either the
headlamp or parking lamp position.
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. Daytime running lamps are required to
function at all times on all vehicles rst sold
in Canada.
A light sensor on top of the instrument panel
makes the DRL work, so be sure it is not covered.
The DRL system will make the low-beam
headlamps come on at reduced brightness when
the following conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness.
The turn signal, taillamps, sidemarker and other
lamps will not be on. The instrument panel cluster
will not be lit up either.
When it is dark enough outside, the DRL will turn
off and the vehicle’s headlamps and parking
lamps will turn on. The other lamps that come on
with the headlamps will also come on.
When it is bright enough outside, the headlamps
will go off and the DRL will come on.
To idle the vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking
lamp position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to
off and back to AUTO.
This feature is not available for vehicles rst sold
in Canada.

It also re-displays for three seconds if the
message has been acknowledged, but the
condition still exists when the engine is turned off.
If the condition still exists, the message
re-appears when the engine is turned on.

TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires,
the identication codes need to be matched to
the new tire/wheel position. The sensors are
matched, to the tire/wheel positions, in the
following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver
side rear tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
You have two minutes to match each tire and
wheel position. If it takes longer than two minutes
to match any tire and wheel position, the
matching process stops and you need to
start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Press the Remote Keyless Entry (RKE)
transmitter’s Lock and Unlock buttons at
the same time for approximately ve seconds.
The horn sounds twice to signal the receiver
is in relearn mode and the TPMS sensor
matching process can begin.
4. Start with the driver’s side front tire.
5. Remove the valve cap from the tire’s valve
stem. Activate the TPMS sensor by
increasing or decreasing the tire’s air
pressure for ten seconds, or until a horn
chirp sounds. The horn chirp, which
may take up to 30 seconds to sound,
conrms that the sensor identication code
has been matched to the tire/wheel
position. To decrease the tire’s air-pressure
use the pointed end of the valve cap,
a pencil-style air pressure gage, or a key.
