2007 CHEVROLET IMPALA low oil pressure

The remote vehicle start feature provides two
separate starts, each with 10 minutes of engine
running, or it provides one start with 10 minutes of
engine running that may be extended with 10 more
minutes. If you press and release the transmitter
lock button and then press and hold the remote
start button, on the remote keyless entry
transmitter, again before the rst 10 minutes of
engine running time has expired, 10 minutes are
added to the remaining minutes. For example, if the
lock button and then the remote start buttons are
pressed again after ve minutes of the engine
run time, 10 minutes are added and you now have
15 minutes of engine running. The added
ten minutes are considered a second remote
vehicle start. Once two remote starts or a single
start with a time extension have been provided, the
vehicle must be started normally with the ignition
key to get more remote vehicle starts.
The remote vehicle start feature will not operate if
the key is in the ignition, the hood is not closed
or if there is an emission control system
malfunction.Also, the engine will turn off during a remote
vehicle start if the coolant temperature gets too
high or if the oil pressure gets low.
Vehicles equipped with the remote vehicle start
feature are shipped from the factory with the
remote vehicle start system enabled. The system
may be enabled or disabled through the DIC.
See “REMOTE START” underDIC Vehicle
Customization on page 208for additional
information.
Remote Start Ready
If your vehicle does not have the remote vehicle
start feature, it may have the remote start ready
feature. This feature allows your dealer to add the
manufacturer’s remote vehicle start feature.
If your vehicle has the remote start ready feature,
your remote keyless entry transmitter will have
extended range that will allow you to lock or unlock
your vehicle from about 195 feet (60 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to
your vehicle.

Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such as
after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out.
Of course, you will nd experienced and able
service experts in GM dealerships all across North
America. They will be ready and willing to help
if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the
lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?

Overheated Engine Protection
Operating Mode
This emergency operating mode allows your
vehicle to be driven to a safe place in an
emergency situation. If an overheated engine
condition exists, 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. The coolant temperature gage
will indicate an overheat condition exists. Driving
extended miles (km) and/or towing a trailer 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 310.
Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Coolant Recovery Tank
B. Pressure Cap
C. Electric Engine Cooling Fans

When cleaning your vehicle’s interior, only use
cleaners specically designed for the surfaces
being cleaned. Permanent damage may result
from using cleaners on surfaces for which
they were not intended. Use glass cleaner only on
glass. Remove any accidental over-spray from
other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when
cleaning glass surfaces on your vehicle, you
could scratch the glass and/or cause damage
to the integrated radio antenna and the
rear window defogger. When cleaning the
glass on your vehicle, use only a soft cloth
and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to all safety
instructions on the label. While cleaning your
vehicle’s interior, maintain adequate ventilation by
opening your vehicle’s doors and windows.
Dust may be removed from small buttons and
knobs using a small brush with soft bristles.Your dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you
can also obtain a product from your dealer to
remove odors from your vehicle’s upholstery.
Do not clean your vehicle using the following
cleaners or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
Never apply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior and
does not improve the effectiveness of soil
removal.
Use only mild, neutral-pH soaps. Avoid laundry
detergents or dishwashing soaps with
degreasers. Using too much soap will leave a
residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per gallon
(3.78 L) of water is a good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result
from the use of many organic solvents such as
naptha, alcohol, etc.
