you press the lock button and then hold the
remote start button on the keyless access
transmitter again for at least three seconds before
the rst 10 minutes of engine running time has
expired, 10 minutes is added to the remaining
minutes. For example, if the remote start is
initiated again after ve minutes of the engine run
time, 10 minutes is added and you now have
15 minutes with the engine running. Once
two remote starts or 20 minutes of the engine
running have been provided, the vehicle must be
started using the keyless access with pushbutton
start feature, if the engine needs to be restarted.
SeeStarting the Engine on page 113for more
information regarding the keyless ignition.The remote start feature will not operate if any of
the following occur:
The check engine light is displayed. See
“Check Engine Light” underMalfunction
Indicator Lamp on page 252.
The valet lockout switch is on.
The keyless access transmitter is in the
vehicle.
The vehicle’s hood is open.
The vehicle personalization feature is not
enabled.
An unauthorized vehicle entry or a vehicle
theft was attempted.
Your keyless access transmitter, with the remote
start button, provides an increased range of
operation. However, the range may be less while
the vehicle is running. As a result, you may
need to be closer to your vehicle to turn it off than
you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeKeyless
Access System on page 87.

Engine Coolant Heater
Your vehicle may be equipped with an engine
coolant heater.
In very cold weather, 0°F (−18°C) or colder, the
engine coolant heater can help. You will get easier
starting and better fuel economy during engine
warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
For the 3.6L V6 engine, the cord is located in
the engine compartment on the passenger’s
side of the vehicle in front of the fuse block.
For the 4.6L V8 engine, the cord is located in
the engine compartment on the driver’s
side of the vehicle near the inner fender and
above the strut.
For the 4.4L V8 engine, the cord is located in
the front of the engine compartment, on
the passenger’s side of the vehicle. The plug
will be inside the upper grille cutout.
3. You must remove the plastic cap to access
the plug.

Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
Your vehicle (STS-V only) is equipped with a
feature that disables the wiper system when the
hood is open and your vehicle is stopped. Opening
the hood will automatically park the wipers if
they are not parked. This prevents the wipers from
interfering with hood operation. Be sure the
hood is not opened when you require the vehicle’s
wipers out of the park position, such as when
changing the wiper blades.
Rainsense™ II Wipers
If your vehicle has this feature, the moisture
sensor is mounted on the interior side of the
windshield behind the rearview mirror. It is used to
automatically operate the wipers by monitoring
the amount of moisture build-up on the windshield.
Wipes occur as needed to clear the windshield
depending on driving conditions and the sensitivity
setting. In light rain or snow, fewer wipes will
occur. In heavy rain or snow, wipes will occur more
frequently. The Rainsense™ wipers operate in adelay mode as well as a continuous low or high
speed as needed. If the system is left on for long
periods of time, occasional wipes may occur
without any moisture on the windshield. This is
normal and indicates that the Rainsense™ system
is activated.
To activate the Rainsense™ system, turn the
wiper band to delay mode and select one of the
four sensitivity levels indicated on the wiper stalk.
The position closest to off is the lowest sensitivity
setting, level one. This allows more rain or snow to
collect on the windshield between wipes. Turning
the wiper band away from you to higher sensitivity
levels increases the sensitivity of the system and
frequency of wipes. The highest sensitivity setting,
level four, is closest to low. A single wipe will occur
each time you turn the wiper stalk to a higher
sensitivity level to indicate that the sensitivity level
has been increased.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn
the wipers off when going through an
automatic car wash.

Outlet Adjustment
Use the lever located in the center of each outlet
to change the direction of the airow, either
side-to-side or up and down. Use the thumbwheels
to open or close the outlets to adjust the airow.
Turn the thumbwheel towards the center
console to open the outlets and allow the
maximum amount of air to enter your vehicle. Turn
the thumbwheel towards the vehicle door to
close the outlets and minimize the amount of air
entering the vehicle.
Operation Tips

Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.
If the airow seems low when the fan speed is
at the highest setting, the passenger
compartment air lter may need to be replaced.
For more information, seePassenger
Compartment Air Filter on page 239.
Rear Climate Control System
Your vehicle has a rear climate control system.
The base model includes air outlets in the rear of
the center console for cooling and under-seat
air outlets for heating. The temperature, quantity,
and air delivery location is controlled automatically
by the front climate control system.
Some vehicles are equipped with an optional
climate control panel for the rear passenger,
located on the back of the center console.
The left knob controls the temperature of the air to
the rear passengers. Turning the knob to the
left will make the air cooler. Turning the knob to
the right will make the air warmer.

system, this message displays if a part on the
system is not working properly. If you drive your
vehicle while any of the four sensors are
missing or inoperable, the warning comes on in
about 20 minutes. A sensor would be missing, for
example, if you put different wheels on your
vehicle without transferring the sensors. If the
warning comes on and stays on, there may be a
problem with the TPM. See your dealer.
SERVICE THEFT SYSTEM

If the octane is less than 87, you may notice a
heavy knocking noise when you drive. If this occurs,
use a gasoline rated at 87 octane or higher as soon
as possible. Otherwise, you might damage your
engine. If you are using gasoline rated at 87 octane
or higher and you hear heavy knocking, your engine
needs service.
If your vehicle has the 4.4L V8 engine
(VIN Code D), use premium unleaded gasoline with
a posted octane rating of 91 or higher. For best
performance, use premium unleaded gasoline with
a posted octane rating of 93. In an emergency, you
can use regular unleaded gasoline with an octane
rating of 87 or higher. If 87 octane fuel is used, do
not perform any aggressive driving maneuvers such
as wide open throttle applications. You may also
hear audible spark knock during acceleration. Rell
your tank with premium fuel as soon as possible to
avoid damaging your engine. If you are using
gasoline rated at 91 octane or higher and you hear
heavy knocking, your engine needs service.Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT). General Motors recommends against the
use of gasolines containing MMT. SeeAdditives
on page 367for additional information.
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 may be affected.
