5. Install the coolant recovery tankcap and the pressure cap. After
a day or two of driving, when the
engine is cold, check the coolant
level in the recovery tank. If it is
low, refill it to the COLD
FILL line.
If the coolant in the recovery tank is
constantly low, have a dealer
service department inspect the
vehicle for leaks.
Notice: If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is a coolant temperature
gauge and a warning light on the
instrument panel that indicate an
overheated engine condition. See
Engine Coolant Temperature Gauge
on page 5‑13 andEngine Coolant
Temperature Warning Light on
page 5‑22.
In addition, there is an ENGINE
OVERHEATED IDLE ENGINE and
an ENGINE OVERHEATED STOP
ENGINE message displayed on the
vehicle Driver Information Center
(DIC). See Engine Cooling System
Messages on page 5‑30 for more
information.
If it is decided not to lift the hood
when this warning appears, but
instead get service help right away,
see Roadside Assistance Program
on page 13‑7. If it is decided 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.

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.(Continued)
WARNING (Continued)
SeeOverheated Engine
Protection Operating Mode on
page 10‑21 for information on
driving to a safe place in an
emergency.
If No Steam is Coming from
the Engine Compartment
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 If the overheat warning is displayed
with no sign of steam:
1. Turn the air 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"
in this section.
Overheated Engine
Protection
Operating Mode
This emergency operating mode
allows the vehicle to be driven
to a safe place in an emergency
situation. If an overheated engine
condition exists, an overheat
protection mode which alternates
firing groups of cylinders helps
prevent engine damage. In this
mode, a significant loss in power
and engine performance will be
noticed. The coolant temperature
gauge will indicate an overheat
condition exists. Driving
extended km (mi) 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. See
Engine Oil on page 10‑8.
Power Steering Fluid
The power steering fluid reservoir
is located toward the rear of the
engine compartment on the
passenger side of the vehicle.
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,
do the following:
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.

Black plate (22,1)Chevrolet Impala Owner Manual - 2011
10-22 Vehicle Care
The fluid level should be
somewhere within the
cross‐hatched area on the
dipstick. If the fluid is at the
ADD mark, fluid should be added.
What to Use
To determine what kind of fluid to
use, seeRecommended Fluids and
Lubricants on page 11‑6. Always
use the proper fluid.
Notice: Use of the incorrect fluid
may damage the vehicle and the
damages may not be covered by
the vehicle's warranty. Always
use the correct fluid listed in
Recommended Fluids and
Lubricants on page 11‑6.
Washer Fluid
What to Use
When the vehicle needs windshield
washer fluid, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall below freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid
A WASHER FLUID LOW ADD
FLUID message will be displayed
on the Driver Information Center
(DIC) when windshield washer fluid
needs to be added to the vehicle.
See
Washer Fluid Messages on
page 5‑36 for more information.
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full.
SeeEngine Compartment Overview
on page 10‑6 for more information
on location. Notice:
.When using concentrated
washer fluid, follow the
manufacturer's instructions
for adding water.
.Do not mix water with
ready-to-use washer fluid.
Water can cause the solution
to freeze and damage the
washer fluid tank and other
parts of the washer system.
Also, water does not clean as
well as washer fluid.
.Fill the washer fluid tank only
three-quarters full when it is
very cold. This allows for
fluid expansion if freezing
occurs, which could damage
the tank if it is
completely full.
.Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.

TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS from
functioning properly. Always check
the TPMS malfunction telltale after
replacing one or more tires or
wheels on your vehicle to ensure
that the replacement or alternate
tires and wheels allow the TPMS to
continue to function properly.
SeeTire Pressure Monitor
Operation on page 10‑47 for
additional information.

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the vehicle's tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument panel
cluster. If the warning light comes
on, stop as soon as possible and inflate the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑12.
At the same time, a message to
check the pressure in a specific tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are
inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed by
the driver. For additional information
and details about the DIC operation
and displays, see
Driver Information
Center (DIC) on page 5‑24 andTire
Messages on page 5‑34.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
could be an early indicator that the
air pressure in the tire(s) is getting
low and needs to be inflated to the
proper pressure.

Black plate (48,1)Chevrolet Impala Owner Manual - 2011
10-48 Vehicle Care
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for your
vehicle's tires when they are cold.
SeeVehicle Load Limits on
page 9‑12, for an example of the
Tire and Loading Information label
and its location on your vehicle.
Also see Tire Pressure on
page 10‑44.
Your vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑51, Tire Rotation on
page 10‑51, and Tires on
page 10‑38. Notice:
Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the Tire
Pressure Monitor System (TPMS)
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message is also displayed. The low
tire pressure warning light and DIC
warning message come on at each
ignition cycle until the problem is
corrected. Some of the conditions
that can cause the malfunction light
and DIC message to come on are:
.One of the road tires has been
replaced with the spare tire.
The spare tire does not have a
TPMS sensor. The TPMS
malfunction light and DIC
message should go off once you
re‐install the road tire containing
the TPMS sensor.

The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off.
3. Press the Remote Keyless Entry (RKE) transmitter's lock and
unlock buttons at the same time
for approximately five seconds.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARNING
ACTIVE message displays on
the DIC screen.
4. Start with the driver side front tire. 5. Remove the valve cap from the
valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire's air pressure
for five seconds, or until a
horn chirp sounds. The horn
chirp, which may take up to
30 seconds to sound, confirms
that the sensor identification
code has been matched to this
tire and wheel position.
6. Proceed to the passenger side front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the
procedure in Step 5. 8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5. The horn sounds
two times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the
DIC display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
11. Put the valve caps back on the valve stems.
