2008 CHEVROLET AVALANCHE oil temperature

To manually shut off a remote start, do any of the
following:
Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The vehicle can be remote started two separate times
between driving sequences. The engine will run for
10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote start time
frame, and before the engine stops.
For example, if the lock button and then the remote
start buttons are pressed again after the vehicle
has been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional ten minutes are considered a second
remote vehicle start.
Once two remote starts, or a single remote start with
one time extension has been done, the vehicle must be
started with the key.
After the key is removed from the ignition, the vehicle
can be remote started again.The vehicle cannot be remote started if the key is in the
ignition, the hood is not closed, or if there is an emission
control system malfunction and the check engine light
comes on.
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 that have 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 (With DIC Buttons) on page 3-66
for additional information. If your vehicle does not have
DIC buttons, see your dealer/retailer to enable or disable
the remote vehicle start system.
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/retailer to add the
manufacturer’s remote vehicle start feature.
See your dealer/retailer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature,
the kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you
contact your dealer/retailer in the area where you will be
parking your vehicle. The dealer/retailer can give you
the best advice for that particular area.
Active Fuel Management™
Your vehicle’s V8 engine may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders, depending
on the driving conditions.
When less power is required, such as cruising at a
constant vehicle speed, the system will operate in the
half cylinder mode, allowing your vehicle to achieve
better fuel economy. When greater power demands are
required, such as accelerating from a stop, passing,
or merging onto a freeway, the system will maintain
full-cylinder operation.
If your vehicle has an Active Fuel Management™
indicator, seeDIC Operation and Displays (With DIC
Buttons) on page 3-51orDIC Operation and Displays
(Without DIC Buttons) on page 3-56for more information
on using this display.
Automatic Transmission Operation
There are several different
positions for the shift lever.
Your vehicle has an automatic transmission with an
electronic shift position indicator within the instrument
panel cluster. This display will show the position anytime
the shift lever is moved out of PARK (P).

Oil Pressure Gage
The oil pressure gage shows the engine oil pressure
in psi (pounds per square inch) when the engine
is running. Canadian vehicles indicate pressure in
kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
When the oil pressure reaches the low pressure zone,
the OIL PRESSURE LOW STOP ENGINE message
will appear in the Driver Information Center (DIC). See
DIC Warnings and Messages on page 3-59andEngine
Oil on page 5-15for more information.A reading in the low pressure zone may be caused by a
dangerously low oil level or some other problem causing
low oil pressure. Check your oil as soon as possible.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would not
be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil. United States

The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to the
number of miles (kilometers) driven since the ignition was
last turned on. This can be used if the trip odometer is not
reset at the beginning of the trip.
To use the retro-active reset feature, press and hold the
trip odometer reset stem for at least four seconds. The
trip odometer will display the number of miles (mi) or
kilometers (km) driven since the ignition was last turned
on and the vehicle was moving. Once the vehicle begins
moving, the trip odometer will accumulate mileage. For
example, if the vehicle was driven 5 miles (8 km) before it
is started again, and then the retro-active reset feature is
activated, the display will show 5 miles (8 km). As the
vehicle begins moving, the display will then increase to
5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
