Driving and Operating

is normal system operation; the vehicle does

not need service. Turn LKA off if these

conditions continue.

When the System Does Not Seem to

Work Properly

Recommended Fuel (2.7L L4 and

5.3L V8 Engines)

For diesel engine vehicles, see “Fuel for

Diesel Engines” in the Duramax diesel

supplement.

The system performance may be

affected by:

Fuel

Close vehicles ahead.

Sudden lighting changes, such as when

driving through tunnels.

Top Tier Fuel

GM recommends the use of TOP TIER

Detergent Gasoline to keep the engine clean,

reduce engine deposits, and maintain

optimal vehicle performance. Look for the

TOP TIER Logo or see www.toptiergas.com

for a list of TOP TIER Detergent Gasoline

marketers and applicable countries.

Banked roads.

Roads with poor lane markings, such as

two-lane roads.

If the LKA system is not functioning

properly when lane markings are clearly

visible, cleaning the windshield may help.

Regular unleaded gasoline meeting ASTM

specification D4814 with a posted octane

rating (R+M)/2 of 87 or greater is

recommended. Do not use gasoline with a

posted octane rating of less than 87, as this

will result in reduced performance and

driveability. If heavy knocking is heard when

using gasoline rated at 87 or greater, the

engine needs service.

A camera blocked message may display if

the camera is blocked. Some driver

assistance systems may have reduced

performance or not work at all. An LKA or

LDW unavailable message may display if the

systems are temporarily unavailable. This

message could be due to a blocked camera.

The LKA system does not need service. Clean

the outside of the windshield behind the

rearview mirror.

Do not use any fuel labeled E85 or FlexFuel.

Do not use gasoline with ethanol levels

greater than 15% by volume.

LKA assistance and/or LDW alerts may occur

due to tar marks, shadows, cracks in the

road, temporary or construction lane

markings, or other road imperfections. This

V8 Engine)

Prohibited Fuels

Fuels in Foreign Countries

The U.S., Canada, and Mexico post fuel

octane ratings in anti-knock index (AKI). For

fuel not to use in a foreign country, see

Prohibited Fuels 0 295.

Caution

Do not use fuels with any of the

following conditions; doing so may

damage the vehicle and void its

warranty:

Fuel Additives

For vehicles that are not FlexFuel, fuel

labeled greater than 15% ethanol by

volume, such as mid-level ethanol

blends (16–50% ethanol), E85,

or FlexFuel.

TOP TIER Detergent Gasoline is highly

recommended for use with your vehicle.

If your country does not have TOP TIER

Detergent Gasoline, add ACDelco Fuel

System Treatment Plus−Gasoline to the

vehicle’s gasoline fuel tank at every oil

change or 15 000 km (9,000 mi), whichever

occurs first. TOP TIER Detergent Gasoline and

ACDelco Fuel System Treatment Plus

−Gasoline will help keep your vehicle’s

engine fuel deposit free and performing

optimally.

Premium unleaded gasoline meeting ASTM

specification D4814 with a posted octane

rating (R+M)/2 of 91 or greater is

recommended. If unavailable, unleaded

gasoline with a posted octane rating of

87 may be used, but will result in reduced

performance and driveability. If heavy

knocking is heard when using gasoline rated

at 91 or greater, the engine needs service.

Fuel with any amount of methanol,

methylal, ferrocene, and aniline. These

fuels can corrode metal fuel system

parts or damage plastic and rubber

parts.

Fuel containing metals such as

methylcyclopentadienyl manganese

tricarbonyl (MMT), which can damage

the emissions control system and

spark plugs.

Do not use any fuel labeled E85 or FlexFuel.

Do not use gasoline with ethanol levels

greater than 15% by volume.

Filling the Tank (Pickup Model)

If the vehicle has a diesel engine, see the

Duramax diesel supplement.

Fuel with a posted octane rating of

less than the recommended fuel. Using

this fuel will lower fuel economy and

performance, and may decrease the

life of the emissions catalyst.

An arrow on the fuel gauge indicates which

side of the vehicle the fuel door is on. See

Fuel Gauge 0 111.

Warning (Continued)

Warning

{

Fuel can spray out if the fill nozzle is

inserted too quickly. This spray can

happen if the tank is nearly full, and is

more likely in hot weather. Insert the

fill nozzle slowly and wait for any hiss

noise to stop before beginning to

flow fuel.

Fuel vapors and fuel fires burn violently

and can cause injury or death.

Overfilling the fuel tank by more than

three clicks of a standard fill nozzle may

cause:

Follow these guidelines to help avoid

injuries to you and others:

Vehicle performance issues, including

engine stalling and damage to the fuel

system.

Read and follow all the instructions on

the fuel pump island.

Fuel spills.

Turn off the engine when refueling.

Under certain conditions, fuel fires.

Keep sparks, flames, and smoking

materials away from fuel.

Be careful not to spill fuel. Wait five seconds

after you have finished pumping before

removing the fill nozzle. Clean fuel from

painted surfaces as soon as possible. See

Exterior Care 0 406. Push the fuel door

closed.

Do not leave the fuel pump

unattended.

Avoid using electronic devices while

refueling.

Do not re-enter the vehicle while

pumping fuel.

Warning

{

Keep children away from the fuel

pump and never let children

pump fuel.

If a fire starts while you are refueling, do

not remove the fill nozzle. Shut off the

flow of fuel by shutting off the pump or

by notifying the station attendant. Leave

the area immediately.

The capless refueling system does not have

a fuel cap. Fully insert and latch the fill

nozzle, begin fueling.

Before touching the fill nozzle, touch a

metallic object to discharge static

electricity from your body.

An arrow on the fuel gauge indicates which

side of the vehicle the fuel door is on. See

Fuel Gauge 0 111.

Keep children away from the fuel

pump and never let children

pump fuel.

If the vehicle runs out of fuel and must be

filled from a portable fuel container:

Before touching the fill nozzle, touch a

metallic object to discharge static

electricity from your body.

Warning

{

Fuel vapors and fuel fires burn violently

and can cause injury or death.

Fuel can spray out if the fuel cap is

opened too quickly. 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.

Follow these guidelines to help avoid

injuries to you and others:

1. Locate the capless funnel adapter.

2. Insert and latch the funnel into the

capless fuel system.

Read and follow all the instructions on

the fuel pump island.

Warning

Turn off the engine when refueling.

{

Attempting to refuel from a portable fuel

container without using the funnel

adapter may cause fuel spillage and

damage the capless fuel system. This

could cause a fire. You or others could be

badly burned and the vehicle could be

damaged.

Keep sparks, flames, and smoking

materials away from fuel.

Do not leave the fuel pump

unattended.

Avoid using electronic devices while

refueling.

Do not re-enter the vehicle while

pumping fuel.

3. Remove and clean the funnel adapter

and return it to the storage location.

Warning

{

Dispense fuel only into approved

containers.

Overfilling the fuel tank by more than

three clicks of a standard fill nozzle may

cause:

Do not fill a container while it is

inside a vehicle, in a vehicle's trunk, in

a pickup bed, or on any surface other

than the ground.

Caution

Vehicle performance issues, including

engine stalling and damage to the fuel

system.

If a new fuel cap is needed, get the right

type of cap from your dealer. The wrong

type of fuel cap may not fit properly,

may turn on the malfunction indicator

lamp, and could damage the fuel system

and emissions system. See Malfunction

Indicator Lamp (Check Engine Light) 0 117.

Bring the fill nozzle in contact with

the inside of the fill opening before

operating the nozzle. Maintain contact

until filling is complete.

Fuel spills.

Under certain conditions, fuel fires.

Be careful not to spill fuel. Wait five seconds

after you have finished pumping before

removing the fill nozzle. Clean fuel from

painted surfaces as soon as possible. See

Exterior Care 0 406. Reinstall the cap by

turning it clockwise until it clicks.

Keep sparks, flames, and smoking

materials away from fuel.

Avoid using electronic devices while

pumping fuel.

Filling a Portable Fuel Container

Warning

{

When transporting a fuel container or

other material that can catch fire in

the truck bed, secure the container to

prevent spills.

Never fill a portable fuel container while

it is in the vehicle. Static electricity

discharge from the container can ignite

the fuel vapor. You or others could be
