power outlet on the center console is causing
interference. Examples of these devices are cell
phones and cell phone chargers, two-way radios,
power inverters, or similar items. Try moving the
keyless access transmitter away from these devices
when starting the vehicle. In addition, PDA devices
and remote garage and gate openers may also
generate Electromagnetic Interference (EMI) that
may interfere with the keyless access transmitter.
Do not carry the keyless access transmitter in the
same pocket or bag as these devices.
The vehicle is experiencing Electromagnetic
Interference (EMI). Some locations, such as airports,
automatic toll booths, and some gas stations, have
EMI elds which may interfere with your keyless
access transmitter.

REDUCED ENGINE POWER
This message displays when the vehicle is reducing
engine power because the transmission is being placed
in gear under conditions that may cause damage to
the vehicle’s engine, transmission, or ability to
accelerate. Reduced engine power can affect the
vehicle’s ability to accelerate. If this message is on,
but there is no reduction in performance, proceed
to your destination. The performance may be reduced
the next time the vehicle is driven. The vehicle may
be driven at a reduced speed while this message is on,
but acceleration and speed may be reduced. Anytime
this message stays on, the vehicle should be taken
to your dealer/retailer for service as soon as possible.
RIGHT DOOR AJAR
This message displays anytime the engine is running,
the transmission is not in PARK (P), and the passenger
door is open or ajar. A chime sounds if the vehicle’s
speed is greater than 3 mph (5 km/h).
SERVICE A/C
This message displays when the electronic sensors that
control the air conditioning and heating systems are
no longer working. Have the climate control system
serviced by your dealer/retailer if you notice a drop in
heating and air conditioning efficiency.
SERVICE ABS (Antilock Brake System)
If this message displays when you are driving, stop
as soon as possible and turn the ignition off. Then start
the engine again to reset the system. If the message
stays on, or comes back on again while you are driving,
your vehicle is in need of service. See your
dealer/retailer.
If the SERVICE ABS message is being displayed, the
Traction Control System (TCS) and StabiliTrak
®System
will also be disabled. The Driver Information Center
will scroll three messages: SERVICE ABS, SERVICE
TRACTION SYS, and SERVICE STABILITRAK, and the
antilock brake system and traction control warning
lights on the instrument panel cluster will be illuminated.
SeeAntilock Brake System Warning Light on page 3-51
andTraction Control System (TCS) Warning Light on
page 3-52. The driver can acknowledge these messages
by pressing the RESET button three times. When the
service message is displayed, the computer controlled

Keyless Access System
When the engine is started, Driver 1 or Driver 2 will
display on the screen. A message will not appear on the
screen if the driver is unknown. The number on the
back of the transmitter corresponds to driver 1 or
driver 2. The navigation system can store memory points
for drivers 1 and 2 individually. SeeKeyless Access
System on page 2-5for more information.
OnStar®System
When using the OnStar®system, the audio system will
be muted and the navigation voice prompts will be
disabled during the call. The volume of the OnStar
®call
can be adjusted by using the steering wheel volume
controls. SeeOnStar
®System on page 2-41for
more information.
Global Positioning System (GPS)
The navigation system determines the position of your
vehicle by using satellite signals, various vehicle signals,
and map data.
At times, other interferences such as the satellite
condition, road conguration, the condition of the vehicle
and/or other circumstances can interfere with the
navigation system’s ability to determine the accurate
position of the vehicle.The GPS shows the current position of your vehicle using
signals sent by the GPS Satellites of the United States
Department of Defense. When your vehicle is not
receiving signals from the satellites, a symbol will appear
on the map screen. Refer toSymbols on page 4-44.
This system may not be available or interferences may
occur if any of the following are true:
Signals are obstructed by tall buildings, trees, large
trucks, or a tunnel.
Objects are located on the rear shelf.
Satellites are being repaired or improved.
After-market glass tinting has been applied to the
vehicle’s rear windshield.
Notice:Do not apply after-market glass tinting to
the vehicle’s windows. Glass tinting will interfere
with the system’s ability to receive GPS signals and
cause the system to malfunction. You might have
to replace the window to correct the problem.
This would not be covered by your warranty.
For more information if you are experiencing a problem,
seeIf the System Needs Service on page 4-52and
Problems with Route Guidance on page 4-52.

Driving at Night
Night driving is more dangerous than day driving because
some drivers are likely to be impaired — by alcohol or
drugs, with night vision problems, or by fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by adjusting the inside
rearview mirror.
Slow down and keep more space between you and
other vehicles because your headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into approaching headlamps.
Keep the windshield and all glass on your vehicle
clean — inside and out.
Keep your eyes moving, especially during turns
or curves.
No one can see as well at night as in the daytime.
But, as we get older, these differences increase.
A 50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.
Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction
and affect your ability to stop and accelerate. Always
drive slower in these types of driving conditions
and avoid driving through large puddles and
deep-standing or owing water.
{CAUTION:
Wet brakes can cause accidents. They might
not work as well in a quick stop and could
cause pulling to one side. You could lose
control of the vehicle.
After driving through a large puddle of water
or a car/vehicle wash, lightly apply the brake
pedal until the brakes work normally.
Flowing or rushing water creates strong
forces. Driving through owing water could
cause your vehicle to be carried away. If this
happens, you and other vehicle occupants
could drown. Do not ignore police warnings
and be very cautious about trying to drive
through owing water.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get
and it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with the headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free your
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 5-22.
If your vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to your vehicle’s traction
system in the Index. If the stuck condition is too severe
for the traction system to free the vehicle, turn the
traction system off and use the rocking method.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or others
could be injured. The vehicle can overheat,
causing an engine compartment re or other
damage. Spin the wheels as little as possible
and avoid going above 35 mph (55 km/h) as
shown on the speedometer.
For information about using tire chains on your vehicle,
seeTire Chains on page 6-73.

California Fuel
If your vehicle is certied to meet California Emissions
Standards, it is designed to operate on fuels that
meet California specications. See the underhood
emission control label. If this fuel is not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specications, but emission control system
performance might be affected. The malfunction
indicator lamp could turn on and your vehicle might fail
a smog-check test. SeeMalfunction Indicator Lamp
on page 3-54. If this occurs, return to your authorized
dealer/retailer for diagnosis. If it is determined that
the condition is caused by the type of fuel used, repairs
might not be covered by your warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that help prevent
engine and fuel system deposits from forming, allowing
the emission control system to work properly. In most
cases, you should not have to add anything to the fuel.
However, some gasolines contain only the minimum
amount of additive required to meet U.S. Environmental
Protection Agency regulations. To help keep fuel
injectors and intake valves clean, or if your vehicle
experiences problems due to dirty injectors or valves,look for gasoline that is advertised as TOP TIER
Detergent Gasoline. Also, your dealer/retailer has
additives that will help correct and prevent most
deposit-related problems.
Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines might be available
in your area. We recommend that you use these
gasolines, if they comply with the specications
described earlier. However, E85 (85% ethanol) and
other fuels containing more than 10% ethanol must
not be used in vehicles that were not designed for
those fuels.
Notice:Your vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under your
warranty.
Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance
of the emission control system could be affected.
The malfunction indicator lamp might turn on. If this
occurs, return to your dealer/retailer for service.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 6-12for
the location of the engine air cleaner/lters.
When to Inspect the Engine Air
Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace them at the rst oil change after
each 50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 7-4for more information.
If you are driving in dusty/dirty conditions, inspect the
lters at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filters
To inspect the air cleaner/lters, remove the lters from
the vehicle and lightly shake the lters to release
loose dust and dirt. If the lters remain caked with dirt,
new lters are required.To inspect or replace the lters, do the following:
1. Some XLR-V vehicles, have a single piece black
cover that snaps over the entire air cleaner
assembly. For vehicles with this cover, simply pull it’s
left/right sides toward the outside of the vehicle and
lift up to remove cover. Reinstall the cover when you
are nished inspecting/replacing the lters.
2. Move the clasps on the top of the engine air
cleaner/lter cover forward to unlatch the cover.
6-22

If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Set the climate controls to the highest heat setting
and fan speed and open the windows as necessary.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning does not come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. If you still have the
warning, turn off the engine and get everyone out of
the vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get service
help right away.Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be driven to
a safe place in an emergency situation. If an overheated
engine condition exists and the DIC message ENGINE
HOT, STOP ENGINE is displayed, an overheat
protection mode which alternates ring groups of
cylinders helps prevent engine damage. In this mode,
you will notice a signicant loss in power and engine
performance. Driving extended miles (km) in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life system. SeeEngine Oil
on page 6-16.
