10-24 Vehicle Care
If No Steam Is Coming from
the Engine Compartment
The ENGINE OVERHEATED STOP
ENGINE or the ENGINE
OVERHEATED IDLE ENGINE
message, along with a low coolant
condition, can indicate a serious
problem.
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer. SeeTrailer
Towing on page 9‑79. If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped.
If it is safe to do so, pull off the
road, shift to P (Park) or
N (Neutral) and let the
engine idle.
If the temperature overheat gauge is
no longer in the overheat zone or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle
right away. If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see
“Overheated
Engine Protection Operating Mode”
later in this section.
Overheated Engine
Protection
Operating Mode
If an overheated engine condition
exists and the ENGINE POWER IS
REDUCED message is displayed,
an overheat protection mode which
alternates firing groups of cylinders
helps prevent engine damage. In
this mode, a loss in power and
engine performance will be noticed.
This operating mode allows the
vehicle to be driven to a safe place
in an emergency. Driving extended
distances and/or towing a trailer in
the overheat protection mode
should be avoided.

Black plate (25,1)Chevrolet Avalanche Owner Manual - 2011
Vehicle Care 10-25
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. See
Engine Oil on page 10‑8.
Engine Fan
The vehicle has electric cooling
fans. The fans spinning at low
speed during most everyday driving
might be heard. The fans can turn
off if no cooling is required. Under
heavy vehicle loading, trailer towing,
and/or high outside temperatures,
or if operating the air conditioning
system, the fans can change to high
speed and an increase in fan noise
might be heard. This is normal and
indicates that the cooling system is
functioning properly. The fans
change to low speed when
additional cooling is no longer
required.
Power Steering Fluid
See Engine Compartment Overview
on page 10‑6 for reservoir location.
When to Check Power Steering
Fluid
It is not necessary to regularly
check power steering fluid unless
there is a leak suspected in the
system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
To check the power steering fluid:
1. Turn the key off and let the
engine compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid level on the dipstick.
The level should be at the FULL
COLD mark. If necessary, add only
enough fluid to bring the level up to
the mark.

Towing
Towing the Vehicle
Notice:To avoid damage, the
disabled vehicle should be
towed with all four wheels off the
ground. Care must be taken with
vehicles that have low ground
clearance and/or special
equipment. Always flatbed
on a car carrier.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
See Roadside Assistance Program
(U.S. and Canada) on page 13‑8 or
Roadside Assistance Program
(Mexico) on page 13‑10.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
“Recreational Vehicle Towing” in
this section.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle –such as behind a
motorhome. The two most
common types of recreational
vehicle towing are known as dinghy
towing and dolly towing. Dinghy
towing is towing the vehicle with all
four wheels on the ground. Dolly
towing is towing the vehicle with
two wheels on the ground and
two wheels up on a device known
as a dolly.
Here are some important things
to consider before recreational
vehicle towing:
.What is the towing capacity
of the towing vehicle?
Be sure to read the tow
vehicle manufacturer's
recommendations.
.What is the distance that will be
travelled? Some vehicles have
restrictions on how far and how
long they can tow.
.Is the proper towing equipment
going to be used? See your
dealer or trailering professional
for additional advice and
equipment recommendations.
.Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed. See Before Leaving on
a Long Trip.

Dinghy Towing
Two-Wheel-Drive Vehicles and
Four-Wheel Drive Vehicles with a
Single Speed Automatic
Transfer Case
Notice:If the vehicle is towed
with all four wheels on the
ground, the drivetrain
components could be damaged. The repairs would not be
covered by the vehicle warranty.
Do not tow the vehicle with all
four wheels on the ground.
Two-wheel-drive vehicles and
four-wheel drive vehicles with a
single speed automatic transfer
case should not be towed with
all four wheels on the ground.
Two-wheel-drive transmissions have
no provisions for internal lubrication
while being towed. Four-wheel drive
vehicles with a single speed
automatic transfer case have no
neutral position and will spin the
transmission when the rear
wheels turn.
Four-Wheel Drive Vehicles with a
Two Speed Automatic
Transfer Case
Use the following procedure to
dinghy tow a four-wheel drive
vehicle with a two speed automatic
transfer case:
1. Position the vehicle being towed
behind the tow vehicle and shift
the transmission to P (Park).
2. Turn the engine off and firmly set the parking brake.
3. Securely attach the vehicle being towed to the tow vehicle.

Vehicle Care 10-95
{WARNING
Shifting a four-wheel-drive
vehicle's transfer case into
N (Neutral) can cause the vehicle
to roll even if the transmission is
in P (Park). The driver or others
could be injured. Make sure the
parking brake is firmly set before
the transfer case is shifted to
N (Neutral).
4. Shift the transfer case to N (Neutral). See “Shifting into
Neutral” under“Four-Wheel
Drive” for the proper procedure
to select the Neutral position for
the vehicle.
5. Release the parking brake only after the vehicle being towed is
firmly attached to the towing
vehicle.
6. Turn the ignition to LOCK/OFF and remove the key —the
steering wheel will still turn. After towing, see
“Shifting Out of
Neutral” under“Four-Wheel Drive”
for the proper procedure to take the
vehicle out of the Neutral position.

Notice: If a two-wheel drive
vehicle or a four-wheel drive
vehicle with a single speed
automatic transfer case is towed with the rear wheels on the
ground, the transmission could
be damaged. The repairs would
not be covered by the vehicle
warranty. Never tow the vehicle
with the rear wheels on the
ground.
Two-wheel-drive vehicles and
four-wheel drive vehicles with a
single speed automatic transfer
case should not be towed with the
rear wheels on the ground.
Two-wheel-drive transmissions have
no provisions for internal lubrication
while being towed. Four-wheel drive
vehicles with a single speed
automatic transfer case have no
neutral position and will spin the

To dolly tow a two‐wheel‐drive
vehicle or a four-wheel drive vehicle
with a single speed automatic
transfer case, the vehicle must be
towed with the rear wheels on the
dolly. See
“Rear Towing (Rear
Wheels Off the Ground)” later in this
section for more information.
