Lighting 6-3
Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system will make either
the reduced intensity low‐beam
headlamps or dedicated DRLs come
on when the following conditions
are met:
.It is still daylight and the ignition
is in ON/RUN or START.
.The exterior lamp control is in off
or AUTO and the headlamps
are off.
.The automatic transmission is
not in P (Park).
When DRLs are on, only the
reduced intensity low‐beam
headlamps or dedicated DRLs will be on. The other exterior lamps and
the instrument panel cluster will not
be on.
When the exterior lamp control is in
AUTO and it is dark enough outside,
the DRL turns off and the low-beam
headlamps will turn on. When it is
bright enough outside, the low-beam
headlamps will go off, and the DRL
will turn back on. If the vehicle is
started in a dark garage, the
automatic headlamp system comes
on immediately. Once the vehicle
leaves the garage, it takes about
one minute for the automatic
headlamp system to change to DRL
if it is light outside. During that
delay, the instrument panel cluster
may not be as bright as usual. Make
sure the instrument panel brightness
lever is in the full bright position.
See
Instrument Panel Illumination
Control on page 6‑5.
Turning the exterior lamp control to
off or to the low-beam headlamp
position will turn off the DRL. If the parking lamps or the fog lamps were
turned on instead, the DRL will still
turn off.
This will work regardless of gear
position and whether or not the
parking brake is set.
Automatic Headlamp
System
When it is dark enough outside and
the exterior lamps control is in the
automatic position, the headlamps
come on automatically. See
Exterior
Lamp Controls on page 6‑1.
The vehicle has a light sensor
located on top of the instrument
panel. Make sure it is not covered,
or the headlamps will be on when
they are not needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.

9-42 Driving and Operating
.To slow down in small amounts,
press the−SET button on the
steering wheel briefly. Each time
this is done, the vehicle goes
about 1.6 km/h (1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle's speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previous set cruise speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to keep the
vehicle's speed down. When the
brakes are applied the cruise control
is disengaged. Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal
(manual and automatic
transmissions).
.Press the clutch pedal to the
floor (manual transmissions).
.Press[on the steering wheel.
.To turn off the cruise control,
press
Ion the steering wheel.
Erasing Speed Memory
The cruise control set speed is
erased from memory by pressing
the
Ibutton or if the ignition is
turned off.
Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it assists the driver with parking and
avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph),
and the sensors on the rear bumper
detect objects up to 2.4m (8 ft)
behind the vehicle, and at least
25.4 cm (10 in) off the ground.

.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the vehicle's tires. The
DIC message should go off after
successfully completing the
sensor matching process. See
“TPMS Sensor Matching
Process”later in this section.
.One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer for
service.
.Replacement tires or wheels do
not match your vehicle's original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. See Buying
New Tires on page 10‑83.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer for
service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors or rotate your vehicle's
tires, the identification 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 can also be
matched to each tire/wheel position
by increasing or decreasing the
tire's air pressure. If increasing the
tire's air pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall. To
decrease the tire's air-pressure use
the pointed end of the valve cap, a
pencil-style air pressure gauge,
or a key.
You have two minutes to match the
first tire/wheel position, and
five minutes overall, to match all
four tire/wheel positions. If it takes
longer than two minutes, to match
the first tire and wheel, or more than
five minutes to match all four tire
and wheel positions, 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 ON/
RUN with the engine off.

Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or
corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and
wheel nuts should be replaced.
If the wheel leaks air, replace it
(except some aluminum wheels,
which can sometimes be repaired).
See your dealer if any of these
conditions exist.
Your dealer will know the kind of
wheel you need.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one it
replaces.If you need to replace any of the
wheels, wheel bolts, wheel nuts,
or Tire Pressure Monitor System
(TPMS) sensors, replace them only
with new GM original equipment
parts. This way, you will be sure to
have the right wheel, wheel bolts,
wheel nuts, and TPMS sensors for
the vehicle.
{WARNING
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts on your vehicle can be
dangerous. It could affect the
braking and handling of your
vehicle, make your tires lose air
and make you lose control. You
could have a collision in which
you or others could be injured.
Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.Notice:
The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration,
headlamp aim, bumper height,
vehicle ground clearance, and tire
or tire chain clearance to the
body and chassis.
See If a Tire Goes Flat
on
page 10‑90for more information.
