30 Keys, Doors, and Windows
When the engine starts, the
parking lamps will turn on and
remain on while the engine is
running. The doors will be
locked.
The engine will continue to run
for 10 minutes. After
30 seconds, repeat the steps if
a 10-minute extension is
desired. Remote start can be
extended only once.
After entering the vehicle during a
remote start, turn the ignition on to
drive the vehicle.
A maximum of two remote starts or
a start with an extension are
allowed between ignition cycles.
If the remote start procedure is used
again before the first 10-minute time
frame has ended, the first
10 minutes will immediately expire
and the second 10-minute time
frame will start.
After the engine has been remote
started two times or a start with an
extension, the ignition must be turned on and then off before the
remote start procedure can be used
again.
To cancel a remote start do any of
the following:
.
Press and hold
/until the
parking lamps turn off.
. Turn on the hazard warning
flashers.
. Turn the ignition on and then off.
The remote vehicle start feature will
not operate if:
. The key is in the ignition.
. The hood is open.
. The hazard warning flashers
are on.
. There is an emission control
system malfunction. See
Malfunction Indicator Lamp
0107.
. The engine coolant temperature
is too high.
. The oil pressure is low. .
Two remote starts or a start with
an extension have already been
provided.
To turn on or off, see Vehicle
Personalization 0119.Door Locks
{Warning
.
Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. When a
door is locked, the handle
will not open it. The chance
of being thrown out of the
vehicle in a crash is
increased if the doors are
not locked. So, all
passengers should wear
seat belts properly and the
doors should be locked
whenever the vehicle is
driven.

104 Instruments and Controls
Engine Coolant
Temperature Gauge
Metric
English
This gauge shows the engine
coolant temperature.
It also provides an indicator of how
hard the vehicle is working. During a
majority of the operation, the gauge
will read 100 °C (210 °F) or less.
If the vehicle is pulling a load or
going up hills, it is normal for the
temperature to fluctuate and
approach the 122 °C (250 °F) mark.
If the gauge reaches the 125 °C
(260 °F) mark, it indicates that the
cooling system is working beyond
its capacity.
See Engine Overheating 0248.
Voltmeter Gauge
When the engine is not running, but
the ignition is on, this gauge shows
the battery's state of charge in
DC volts.
When the engine is running, the
gauge shows the condition of the
charging system. Readings between
the low and high warning zones
indicate the normal operating range.
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
at an idle for an extended period.

Retained Accessory
Power (RAP)
These vehicle accessories can be
used for up to 10 minutes after the
engine is turned off:
.Audio System
. Power Windows (if equipped)
These features will work when the
ignition is on or in ACC/
ACCESSORY. Once the ignition is
turned from on to off, power to the
radio and power windows will
continue to work for 10 minutes or
until the driver door is opened.
Engine Coolant Heater
If the vehicle has a diesel engine,
see the Duramax diesel
supplement.
{Warning
Do not plug in the engine block
heater while the vehicle is parked
in a garage or under a carport.
Property damage or personal
injury may result. Always park the
vehicle in a clear open area away
from buildings or structures.
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below −18 °C (0 °F). Vehicles
with an engine coolant heater
should be plugged in at least four
hours before starting. An internal
thermostat in the plug end of the
cord may exist which will prevent
engine coolant heater operation at
temperatures above −18 °C (0 °F).
To Use the Engine Coolant
Heater
1. Turn off the engine.

4. Open the hood and unwrap theelectrical cord.
For V6 engines, the cord for
the engine coolant heater is on
the driver side of the engine
compartment.
For V8 engines, the cord for
the engine coolant heater is
behind the engine air cleaner/
filter.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
5. Plug it into a normal, grounded 110-volt AC outlet.{Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
. Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection
function. An ungrounded
outlet could cause an
electric shock.
. Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension
cord in good operating
condition, or using a
damaged heater or
extension cord, could make

Warning (Continued)
it overheat and cause a fire,
property damage, electric
shock, and injury.
. Do not operate the vehicle
with the heater cord
permanently attached to the
vehicle. Possible heater
cord and thermostat
damage could occur.
. While in use, do not let the
heater cord touch vehicle
parts or sharp edges. Never
close the hood on the
heater cord.
. Before starting the vehicle,
unplug the cord, reattach
the cover to the plug, and
securely fasten the cord.
Keep the cord away from
any moving parts.
6. Before starting the engine, be sure to unplug and store the
cord as it was before to keep it
away from moving engine parts
and prevent damage.

Driving and Operating 213
Making TurnsCaution
Turn more slowly and make wider
arcs when towing a trailer to
prevent damage to your vehicle.
Making very sharp turns could
cause the trailer to contact the
vehicle.
Make wider turns than normal when
towing, so trailer will not go over soft
shoulders, over curbs, or strike road
signs, trees, or other objects.
Always signal turns well in advance.
Do not steer or brake suddenly.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downhill grade. If the
transmission is not shifted down, the
brakes may overheat and result in
reduced braking efficiency. The vehicle can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts too
often under heavy loads and/or hilly
conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle could show signs similar to
engine overheating. To avoid this,
let the engine run, preferably on
level ground, with the transmission
in P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating
0248.Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and
trailer on a level surface when
possible. When parking your vehicle and your
trailer on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the
brake pedal to allow the chocks
to absorb the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the engine.
. Shift into a gear.
. Release the parking brake.
2. Let up on the brake pedal.
