coolant temperature PONTIAC GRAND PRIX 2008 Owners Manual

If it is the rst remote start since the vehicle has been
driven, repeat the previous steps, while the engine is still
running, to extend the engine running time by 10 minutes
from the time you repeat the steps for remote starting.
The remote start running time can be extended one time
and only after the rst remote start.
After entering the vehicle during a remote start, insert
and turn the key to ON/RUN to drive the vehicle.
The engine will shut off automatically after 10 minutes,
unless a time extension has been done or the
vehicle’s key is inserted into the ignition switch and
turned to ON/RUN.
To manually shut off a remote start, do any of the
following.
Aim the RKE transmitter at the vehicle and press
and release the remote start button.
Turn on the hazard warning ashers.
Turn the ignition switch out of LOCK/OFF position
and then back to LOCK/OFF.
The parking lamps turn off to indicate the engine is off.After the engine has been started two times, or one
time with a time extension, the vehicle’s ignition must
be turned to ON/RUN using the key before the remote
start procedure can be used again. SeeIgnition
Positions on page 2-23for information regarding the
ignition positions on your vehicle.
The remote vehicle start feature will not operate if any
of the follow occur:
The remote start system is disabled through the DIC.
The vehicle’s key is in the ignition.
A door on the vehicle is open.
The vehicle’s hood is open.
The hazard warning ashers are on.
There is an emission control system malfunction.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts, or one start with a time
extension, have already been provided for that
ignition cycle.

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 ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
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
briey but then stops again, do the same thing.
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 your vehicle. If you add electrical parts
or accessories, you could change the way the engine
operates. Before adding electrical equipment, check
with your dealer/retailer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.Engine Coolant Heater
The engine coolant heater, if available, can help in
cold weather conditions at or below 0°F (−18°C)
for easier starting and better fuel economy during
engine warm-up. Plug in the coolant heater at least
four hours before starting your vehicle. An internal
thermostat in the plug-end of the cord may exist
which will prevent engine coolant heater operation
at temperatures above 0°F (−18°C).
2-26

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located above the engine air
cleaner/lter. SeeEngine Compartment
Overview on page 5-12for more information
on location.
3. Plug the cord into a normal, grounded
110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord
will not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug and
store the cord as it was before, making sure to
keep it away from moving engine parts. If this is
not done, the cord could be damaged.
How long should the coolant heater be kept plugged in?
The answer depends on the outside temperature, the
kind of oil that is in the vehicle, and some other things.
Instead of trying to list everything here, we ask that
you contact your dealer/retailer in the area where the
vehicle will be parked. The dealer/retailer can give
you the best advice for that particular area.

If the uid level is low, add only enough of the proper
uid to bring the level into the crosshatched area on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at the
dipstick hole to bring it to the proper level.
It does not take much uid, generally less than one
pint (0.5 L). Do not overll.
Notice:Use of the incorrect automatic transmission
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always use
the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 6-12.
3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
4. When the correct uid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if only
DEX-COOL
®extended life coolant is added.The following explains the cooling system and how to
add coolant when it is low. If there is a problem with
engine overheating or if coolant needs to be added to the
radiator, seeEngine Overheating on page 5-27.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®engine coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
