2010 CHEVROLET HHR brake sensor

When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They also turn
off 15 seconds after the windshield wiper control is
turned off.
Headlamps on Reminder
If the drivers door is opened with the ignition off and the
lamps on, a warning chime will sound. This indicates
that the headlamps are still on.
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 vehicle has a light sensor on top of the instrument
panel. Do not cover this sensor or the headlamps will
come on when they are not needed.
The DRL system will make the headlamps come on at
reduced brightness when the following conditions
are met:
.The ignition is on.
.The exterior lamp control is turned to AUTO.
.The light sensor detects daytime light.
.The shift lever is not in P (Park).While the DRL system is on, the taillamps, sidemarker
lamps, and instrument panel lights will not be on.
For vehicles with an Automatic Transmission, the DRL
system is off any time the vehicle is in P (Park). For
vehicles with a Manual Transmission, the DRL system
will be off when the vehicle is first started, the park
brake is applied, and the vehicle has not moved. The
DRL system on U.S. vehicles can also be turned off by
using the off/on switch for one ignition cycle.
The regular headlamp system should be turned on
when needed.
Automatic Headlamp System
When it is dark enough outside, the automatic system
turns on the headlamps at the normal brightness along
with other lamps such as the taillamps, sidemarker,
parking lamps, instrument panel lights, and interior
switch backlighting.
Do not cover the light sensor, located on top of the
instrument panel. If the sensor is covered the
headlamps may remain on when they are not needed.
If the vehicle is driven through a parking garage,
overcast weather or a tunnel, the automatic headlamp
system may turn on.

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 the vehicle is started in a dark garage, the automatic
lamp system turns on immediately. Once the vehicle
exits the garage, it will take about 20 seconds for the
automatic lamp 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 control is in the full bright
position. SeeInstrument Panel Brightness
on
page 4‑14.
To idle the vehicle with the system off, turn the ignition
on and turn the exterior light switch to the off/on
position. For vehicles first sold in Canada, the
transmission must stay in P (Park) for this function
or the parking brake must be set for vehicles with
manual transmissions.
Turn on the regular headlamps when they are needed.
Fog Lamps
For vehicles with fog lamps, the button is located on the
instrument panel, to the right of the steering wheel.
The ignition must be on to use the fog lamps.
#: Press to turn the fog lamps on and off. An indicator
light on the button comes on when the fog lamps
are on.
The parking lamps automatically turn on and off when
the fog lamps are turned on and off.
The fog lamps will turn off while the high-beam
headlamps are turned on.
Some localities have laws that require the headlamps to
be on along with the fog lamps.

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 the vehicle's tires, the identification codes
need to be matched to the new tire/wheel location. The
sensors are matched, to the tire/wheel locations, 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/
retailer for service.
The TPMS sensors can 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 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 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 ON/RUN with the engine off. 3. Press and hold the Remote Keyless Entry (RKE)
transmitter's LOCK and UNLOCK buttons, at the
same time, for about five seconds to start the
TPMS learn mode. The horn sounds twice
indicating the TPMS receiver is ready and in
learn mode.
4. Start with the driver side front tire. The driver side front turn signal also comes on to indicate that
corner's sensor is ready to be learned.
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 about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals flash one time to confirm the
sensor identification code has been matched to the
tire/wheel position.
6. The passenger side front turn signal comes on to indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and repeat
the procedure in Step 5.
7. The passenger side rear turn signal comes on to indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and repeat
the procedure in Step 5.

Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned and
balanced carefully at the factory to give you the longest
tire life and best overall performance. Adjustments
to wheel alignment and tire balancing will not be
necessary on a regular basis. However, if you notice
unusual tire wear or your vehicle pulling to one side or
the other, the alignment might need to be checked.
If you notice your vehicle vibrating when driving on a
smooth road, the tires and wheels might need to be
rebalanced. See your dealer/retailer for proper
diagnosis.
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/retailer if any of these conditions exist.
Your dealer/retailer 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 your 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 your 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 Changing a Flat Tire
on page 6‑88for more
