fuel cap CHEVROLET TAHOE 2010 3.G Owners Manual

The Tire Pressure Monitor can alert you about low tire
pressure, but it does not replace normal monthly tire
maintenance. It is the driver’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 6‑73and
Tire Pressure Monitor Operation on page 6‑74.
Engine Oil Life System
The engine oil life system calculates engine oil life
based on vehicle use and, on most vehicles, displays
a DIC message when it is necessary to change the
engine oil and filter. The oil life system should be reset
to 100% only following an oil change.
Resetting the Oil Life System
To reset the Engine Oil Life System on most vehicles:
1. Display the OIL LIFE REMAINING on the DIC. If the vehicle does not have DIC buttons, the
vehicle must be in P (Park) to access this display.
2. Press and hold the SET/RESET button on the DIC, or the trip odometer reset stem if the vehicle does
not have DIC buttons, for more than five seconds.
The oil life will change to 100%. On all vehicles, the Engine Oil Life System can be reset
as follows:
1. Turn the ignition to ON/RUN with the engine off
2. Fully press the accelerator pedal slowly three times within five seconds.
3. Display the OIL LIFE REMAINING on the DIC. If the display shows 100%, the system is reset.
See Engine Oil Life System on page 6‑20.
Fuel E85 (85% Ethanol)
Vehicles that have the 5.3L V8 engine (VIN Code 0),
the 5.3L V8 engine (VIN Code 3), the 6.0L V8 engine
(VIN Code J), or the 6.2L V8 engine (VIN Code 2) have
a yellow fuel cap and can use either unleaded gasoline
or ethanol fuel containing up to 85% ethanol (E85).

Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.
An emission system malfunction might be corrected by
doing the following:
.Make sure the fuel cap is fully installed. See Filling
the Tankon page 6‑11. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should
turn the light off.
.If the vehicle has been driven through a deep
puddle of water, the vehicle's electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
.Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run as
efficiently as designed and can cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misfiring, hesitation on acceleration,
or stumbling on acceleration. These conditions
might go away once the engine is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one full
tank of the proper fuel to turn the light off.
See Gasoline Octane on page 6‑7.
If none of the above have made the light turn off, your
dealer can check the vehicle. The dealer has the
proper test equipment and diagnostic tools to fix any
mechanical or electrical problems that might have
developed.

The gauge first indicates empty before the vehicle is out
of fuel, and the vehicle's fuel tank should be filled soon.
When the fuel tank is low, the FUEL LEVEL LOW
message appears in the Driver Information Center
(DIC). SeeDIC Warnings and Messages
on page 4‑61for more information.
Here are some situations owners may experience with
the fuel gauge. None of these indicate a problem with
the fuel gauge.
.At the gas station, the fuel pump shuts off before
the gauge reads full.
.It takes a little more or less fuel to fill up than the
fuel gauge indicated. For example, the gauge may
have indicated the tank was half full, but it actually
took a little more or less than half the tank's
capacity to fill the tank.
.The gauge goes back to empty when the ignition is
turned off.
For vehicles with a Two-mode Hybrid, see the
Two-mode Hybrid manual for more information.
Low Fuel Warning Light
This light, under the fuel
gauge, comes on briefly
while the engine is being
started.
This light and a chime comes on when the fuel tank is
low on fuel. The Driver Information Center also displays
a “FUEL LEVEL LOW” message. SeeDIC Warnings
and Messages
on page 4‑61for more information.
When fuel is added this light and message should go
off. If it does not, have the vehicle serviced by your
dealer.
4-46

There are several conditions that can cause this
message to appear.
.One condition is overheating, which could occur if
StabiliTrak activates continuously for an extended
period of time.
.The message also displays if the brake system
warning light is on. SeeBrake System Warning
Light on page 4‑36.
.The message could display if the stability system
takes longer than usual to complete its diagnostic
checks due to driving conditions.
.The message displays if an engine or vehicle
related problem has been detected and the vehicle
needs service. See your dealer.
.The message also displays if the vehicle is shifted
into 4LO (Two Speed Transfer Case Only).
The message turns off as soon as the conditions that
caused the message to be displayed are no longer
present.
TIGHTEN GAS CAP
This message may display along with the check engine
light on the instrument panel cluster if the vehicle's fuel
cap is not tightened properly. See Malfunction Indicator
Lamp
on page 4‑39. Reinstall the fuel cap fully. See
Filling the Tankon page 6‑11. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap allows
fuel to evaporate into the atmosphere. A few driving
trips with the cap properly installed should turn this light
and message off.
TIRE LEARNING ACTIVE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the TPMS is
re-learning the tire positions on your vehicle. The tire
positions must be re-learned after rotating the tires or
after replacing a tire or sensor. See Tire Inspection and
Rotation
on page 6‑78, Tire Pressure Monitor Systemon page 6‑73, and Inflation - Tire Pressureon
page 6‑72for more information.

This is called Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight of the
vehicle, all occupants, fuel, and cargo.
The Certification/Tire label also tells you the
maximum weights for the front and rear axles,
called Gross Axle Weight Rating (GAWR). To find
out the actual loads on your front and rear axles,
you need to go to a weigh station and weigh your
vehicle. Your dealer can help you with this. Be
sure to spread out your load equally on both sides
of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
The Certification/Tire label also contains
information about your Front Axle Reserve
Capacity.
And, if you do have a heavy load, you should
spread it out.
{CAUTION:
Do not load the vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do, parts
on the vehicle can break, and it can change
the way your vehicle handles. These could
cause you to lose control and crash. Also,
overloading can shorten the life of the
vehicle.
Notice :Overloading the vehicle may cause
damage. Repairs would not be covered by the
vehicle warranty. Do not overload the vehicle.
The label will help you decide how much cargo
and installed equipment your truck can carry.
Using heavier suspension components to get
added durability might not change your weight
ratings. Ask your dealer to help you load your
vehicle the right way.

Here are some guidelines for safely carrying a snow
plow on your vehicle:
.Make sure the weight on the front and rear axles
does not exceed the axle rating for each.
.For the front axle, if more cargo or passengers
must be carried, appropriate counter ballast must
be installed rear of the rear axle. Counter ballast
must be properly secured so it will not move during
driving.
.Follow the snow plow manufacturer's
recommendations regarding rear ballast. Rear
ballast may be required to ensure a proper front
and rear weight distribution ratio, even though the
actual weight at the front axle may be less than the
front axle rating.
.The snow plow manufacturer or installer can assist
you in determining the amount of rear ballast
required, to help make sure your snowplow/vehicle
combination does not exceed the GVW rating, the
front and rear axle ratings, and the front and rear
weight distribution ratio.
.The total vehicle must not exceed the GVW rating.Front axle reserve capacity is the difference between
your front Gross Axle Weight Rating (GAWR) and the
front axle weight of your vehicle with full fuel and
passengers. Basically, it is the amount of weight you
can add to your front axle before reaching your
front GAWR.
The front axle reserve capacity for your vehicle can be
found in the lower right corner of the Certification/Tire
label, as shown.United StatesCanada

{WARNING:
On some vehicles that have certain front mounted
equipment, such as a snow plow, it may be
possible to load the front axle to the front gross
axle weight rating (GAWR) but not have enough
weight on the rear axle to have proper braking
performance. If your brakes can not work properly,
you could have a crash. To help your brakes work
properly when a snow plow is installed, always
follow the snow plow manufacturer or installer's
recommendation for rear ballast to ensure a
proper front and rear weight distribution ratio,
even though the actual front weight may be less
than the front GAWR, and the total vehicle weight
is less than the gross vehicle weight rating
(GVWR). Maintaining a proper front and rear
weight distribution ratio is necessary to provide
proper braking performance.Total vehicle reserve capacity is the difference between
your GVWR and the weight of your vehicle with full fuel
and passengers. It is the amount of weight you can add
to your vehicle before reaching your GVWR. Keep in
mind that reserve capacity numbers are intended as
a guide when selecting the amount of equipment or
cargo your vehicle can carry. If you are unsure of your
vehicle's front, rear, or total weight, go to a weigh
station and weigh your vehicle. Your dealer can also
help you with this.
The total vehicle reserve capacity for your vehicle can
be found in the lower right corner of the Certification/
Tire label as shown previously.
See your dealer for additional advice and information
about using a snow plow on your vehicle. Also, see
Loading the Vehicle on page 5‑29.
Emergency Roof Lamp Provisions
Vehicles with the RPO VYU snow plow prep package
also have an emergency roof lamp provision package,
RPO TRW. Wiring for the emergency roof lamp is
provided above the overhead console. See
Auxiliary
Roof-Mounted Lamp
on page 4‑14for switch location.

Autoride also interacts with the tow/haul mode that,
when activated, will provide additional control of the
shock absorbers. This additional control results in better
ride and handling characteristics when the vehicle is
loaded or towing a trailer. See“Tow/Haul Mode”under
Towing a Trailer
on page 5‑47for more information.
Towing a Trailer
If the vehicle has a two–mode hybrid engine, see the
Two–mode Hybrid manual for more information.
Do not tow a trailer during break‐in. See New Vehicle
Break-In
on page 3‑26for more information.
{WARNING:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well —or
even at all. The driver and passengers could be
seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer for advice and information about
towing a trailer with the vehicle. Notice:
Pulling a trailer improperly can damage the
vehicle and result in costly repairs not covered by
the vehicle warranty. To pull a trailer correctly,
follow the advice in this section and see your dealer
for important information about towing a trailer with
the vehicle.
To identify the trailering capacity of the vehicle, read the
information in “Weight of the Trailer” that appears later
in this section.
Trailering is different than just driving the vehicle
by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment,
and it has to be used properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers. So please read this section carefully before
pulling a trailer.

Filling the Tank
{WARNING:
Fuel vapor burns violently and a fuel fire can
cause bad injuries. To help avoid injuries to you
and others, read and follow all the instructions on
the fuel pump island. Turn off the engine when
refueling. Do not smoke near fuel or when
refueling the vehicle. Do not use cellular phones.
Keep sparks, flames, and smoking materials away
from fuel. Do not leave the fuel pump unattended
when refueling the vehicle. This is against the law
in some places. Do not re-enter the vehicle while
pumping fuel. Keep children away from the fuel
pump; never let children pump fuel.
The tethered fuel cap is located behind a hinged fuel
door on the driver side of the vehicle. If the vehicle
has E85 fuel capability, the fuel cap will be yellow and
state that E85 or gasoline can be used. SeeFuel E85
(85% Ethanol) on page 6‑9.
6-11

To open the fuel door, push the rearward center edge in
and release and it will open.
To remove the fuel cap, turn it slowly counterclockwise.
The fuel cap has a spring in it; if the cap is released too
soon, it will spring back to the right.
While refueling, hang the tethered fuel cap from the
hook on the fuel door.
{WARNING:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.
Be careful not to spill fuel. Do not top off or overfill the
tank and wait a few seconds after you have finished
pumping before removing the nozzle. Clean fuel from
painted surfaces as soon as possible. See Washing
Your Vehicle on page 6‑111.
When replacing the fuel cap, insert the tether in its hole
before tightening the cap. Turn the fuel cap clockwise
until it clicks. It will require more effort to turn the fuel
cap on the last turn as you tighten it. Make sure the cap
is fully installed. The diagnostic system can determine
if the fuel cap has been left off or improperly installed.
This would allow fuel to evaporate into the atmosphere.
See Malfunction Indicator Lamp on page 4‑39.
