one time.
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.For example, if the lock button and
then the remote start buttons are
pressed again after the vehicle
has been running for five minutes,
10 minutes are added, allowing
the engine to run for a total of
15 minutes.
A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles.
After the vehicle's engine has been
started two times using the remote
start button, the ignition must be
turned on and then back off before
the remote start procedure can be
used again.

9-20 Driving and Operating
To prevent gear damage, this
system also prevents cranking
if the engine is already running.
Engine cranking can be stopped
by turning the ignition switch
to the ACC/ACCESSORY or
LOCK/OFF position.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start
after 5‐10 seconds, especially in
very cold weather (below 0°F or
−18°C), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the
way to the floor and holding it
there as you hold the key in
START for up to a maximum
of 15 seconds. Wait at least 15 seconds between each try,
to allow the cranking motor to
cool down. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briefly but then stops again,
repeat these steps. This clears
the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the
oil warms up and lubricates
all moving parts.
Notice: The engine is designed
to work with the electronics in
the vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.Engine Heater
The engine coolant heater
can provide easier starting
and better fuel economy during
engine warm-up in cold weather
conditions at or below 0°F (−18°C).
Vehicles with an engine coolant
heater should be plugged in at
least four hours before starting.
Some models may have an internal
thermostat in the cord which will
prevent engine coolant heater
operation at temperatures above
0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The cord is
located on the driver side of the
engine compartment. It is routed
around the windshield washer
fluid reservoir.
3. Plug the cord into a normal, grounded 110-volt AC outlet.

This vehicle has an airbag system.
Before attempting to do your own
service work, see Servicing the
Airbag-Equipped Vehicle on
page 3‑45.
Keep a record with all parts receipts
and list the mileage and the date
of any service work performed.
See Maintenance Records on
page 11‑10.Hood
To open the hood, do the following:
1. Pull the hood release handle
with this symbol on it. It is
located under the instrument
panel on the driver's side of
the vehicle.
2. At the front of the vehicle, pull up on the center of the hood,
and push the secondary hood
release to the right. 3. After you have partially
lifted the hood, gas struts
will automatically take over
to lift and hold the hood in
the fully open position.
Before closing the hood, be sure all
filler caps are on properly.
Pull the hood down to close.
Lower the hood until the lifting
pressure of the strut is reduced.
Then allow the hood to fall and latch
into place under its own weight.
Check to make sure the hood is
closed. If the hood does not fully
latch, gently push the hood down
at the front and center of the hood
until it is completely latched.

10-20 Vehicle Care
If you do decide to lift the hood,
make sure the vehicle is parked
on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: If the engine catches fire
while driving with no coolant, the
vehicle can be badly damaged.
The costly repairs would not be
covered by the vehicle warranty.
See Overheated Engine
Protection Operating Mode on
page 10‑22 for information on
driving to a safe place in an
emergency.If Steam Is Coming from the
Engine Compartment
{WARNING
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or
hear steam coming from it.
Turn it off and get everyone
away from the vehicle until it
cools down. Wait until there is
no sign of steam or coolant
before you open the hood.
(Continued)
WARNING (Continued)
If you keep driving when the
vehicles engine is overheated,
the liquids in it can catch fire.
You or others could be badly
burned. Stop the engine if it
overheats, and get out of the
vehicle until the engine is cool.

10-84 Vehicle Care
Notice:If the radio or other
accessories are left on during
the jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories
when jump starting the vehicle.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
4. Open the hoods and locate the positive (+) and negative (−)
terminal locations on the
other vehicle. Your vehicle
has a remote positive (+) and
a remote negative (−) jump
starting terminal. See Engine
Compartment Overview on
page 10‑6 for more information
on the terminal locations.{WARNING
Using a match near a battery
can cause battery gas to explode.
People have been hurt doing this,
and some have been blinded.
Use a flashlight if you need
more light.
Be sure the batteries have
enough water. You do not need
to add water to the ACDelco
®
battery (or batteries) installed in
your new vehicle. But if a battery
has filler caps, be sure the right
amount of fluid is there. If it is low,
add water to take care of that
first. If you do not, explosive
gas could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{WARNING
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.
5. Check that the jumper cables do not have loose or missing
insulation. If they do, you could
get a shock. The vehicles could
be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) will go
to positive (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative (−) will go to a
heavy, unpainted metal engine
part or to a remote negative (−)
terminal if the vehicle has one.
