Shift Lock Release
If the battery is discharged, the shift
lever may not be moved from the
P (Park) position even with the
brake pedal pressed.
To move the shift lever:1. Place the ignition switch to the LOCK position and remove
the key.
2. Apply the parking brake. 3. Remove the shift lock release
cover using a suitable tool.
4. Push down the shift lock release using a suitable tool.
5. Push the shift lever button and move the shift lever to the
N (Neutral) position while
holding down the shift lock
release.
Place the ignition switch in the ON
position to unlock the steering
wheel. The vehicle may be moved
to the desired location.
Replace the removed shift lock
release cover after the operation.
If the shift lever cannot be moved
out of the P (Park) position, have a
dealer check the CVT system as
soon as possible.
Overdrive (O/D) OFF Switch
When the O/D OFF switch is
pressed with the shift lever in the
D (Drive) position, the light in the
instrument panel illuminates. See
Overdrive Off Light 094.
Use the Overdrive off mode when
you need improved engine braking.
To turn off the Overdrive off mode,

154 Driving and Operating
Each time the engine is started,
or when the shift lever is shifted to
any position other than D (Drive),
the Overdrive off mode will be
automatically turned off.
Accelerator Downshift in D
Position
For passing or hill climbing, press
the accelerator pedal to the floor.
This shifts the transmission down
into a lower gear, depending on the
vehicle speed.
High Fluid Temperature
Protection Mode
If the fluid temperature becomes too
high from climbing a steep grade in
high temperatures, such as towing a
trailer. Engine power and vehicle
speed will be decreased
automatically to reduce the chance
of transmission damage. Vehicle
speed can be controlled with the
accelerator pedal but the engine
and vehicle speed may be limited.Fail Safe
When the fail-safe operation occurs,
the CVT will not be shifted into the
selected driving position.
If the vehicle is driven under
extreme conditions, such as
excessive wheel spinning and
subsequent hard braking, the
fail-safe system may be activated.
The malfunction indicator lamp may
come on to indicate the fail-safe
mode is activated. See
Malfunction
Indicator Lamp (Check Engine
Light) 091. This will occur even if all
electrical circuits are functioning
properly. In this case, place the
ignition switch in the OFF position
and wait for 10 seconds. Then place
the ignition switch back in the ON
position. The vehicle should return
to its normal operating condition. If it
does not return to its normal
operating condition, have a dealer
check the transmission and repair if
necessary.
{Warning
When the high fluid temperature
protection mode or fail-safe
operation occurs, vehicle speed
may be gradually reduced. The
reduced speed may be lower than
other traffic, which could increase
the chance of a collision. Be
especially careful when driving.
If necessary, pull to the side of
the road at a safe place and allow
the transmission to return to
normal operation, or have it
repaired if necessary.

Driving and Operating 171
Warning (Continued)
.Under no circumstances
should either a leaded
gasoline or gasoline with
MMTbe used. Doing so will
damage the catalytic
converter.
. Do not use E85 fuel in your
vehicle. Your vehicle is not
designed to run on E85 fuel.
Using E85 fuel in a vehicle
not specifically designed for
E85 fuel can adversely
damage the emission
control devices and systems
of the vehicle. Damage
caused by such fuel is not
covered by the new vehicle
limited warranty.
Some gasolines, mainly high octane
racing gasolines, can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use
gasolines and/or fuel additives with
MMT as they will reduce spark plug
life and affect emission control system. The malfunction indicator
lamp may turn on. If this occurs, see
your dealer for service.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance may be
affected. The malfunction indicator
lamp could turn on and the vehicle
may not pass a smog-check test.
See
Malfunction Indicator Lamp
(Check Engine Light) 091. If this
occurs, return to your authorized
dealer for diagnosis. If it is
determined that the condition is
caused by the type of fuel used,
repairs may not be covered by the
vehicle warranty.
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” inFuel 0170.
Fuel Additives
To keep fuel systems clean, TOP
TIER detergent gasoline is
recommended. See Fuel0170.
If TOP TIER detergent gasoline is
not available, one bottle of GM Fuel
System Treatment Cleaner added to
the fuel tank at every engine oil
change, can help. GM Fuel System
Treatment Cleaner is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.

Warning (Continued)
.Vehicle performance issues,
including engine stalling and
damage to the fuel system.
. Fuel spills.
. Potential fuel fires.
Be careful not to spill fuel. Wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care 0233.
When replacing the fuel cap, turn it
clockwise until it clicks. Make sure
the cap is fully installed.
{Warning
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Caution
If a new fuel cap is needed, be
sure to get the right type of cap
from your dealer. The wrong type
of fuel cap may not fit properly,
may cause the malfunction
indicator lamp to light, and could
damage the fuel tank and
emissions system. See
Malfunction Indicator Lamp
(Check Engine Light) 091.
LOOSE FUEL CAP Warning
Message
The LOOSE FUEL CAP message
displays in the odometer when the
fuel cap is not tightened correctly
after the vehicle has been refueled.
See Fuel System Messages 099.
Failure to tighten the fuel cap
properly after the LOOSE FUEL
CAP warning message is displayed
may cause the malfunction indicator
light to turn on. See Malfunction
Indicator Lamp (Check Engine
Light) 091.
Filling a Portable Fuel
Container
{Warning
Filling a portable fuel container
while it is in the vehicle can cause
fuel vapors that can ignite either
by static electricity or other
means. You or others could be
badly burned and the vehicle
could be damaged. Always:
. Use approved fuel
containers.
. Remove the container from
the vehicle, trunk, or pickup
bed before filling.
. Place the container on the
ground.
. Place the nozzle inside the
fill opening of the container
before dispensing fuel, and
keep it in contact with the fill
opening until filling is
complete.

{Warning
The Data Link Connector (DLC) is
used for vehicle service and
Emission Inspection/Maintenance
testing. See Malfunction Indicator
Lamp (Check Engine Light) 091.
A device connected to the DLC —
such as an aftermarket fleet or
driver-behavior tracking device —
may interfere with vehicle
systems. This could affect vehicle
operation and cause a crash.
Such devices may also access
information stored in the vehicle’s
systems.

5. Securely place the hood prop into the slot in the front of the
engine compartment. To close the hood:
1. Before closing the hood, be sure all filler caps are on
properly. Then, lift the hood to
relieve pressure on the hood
prop. Remove the hood prop
from the slot in the front of the
engine compartment and return
the prop to its underhood
retainer. The prop rod must
click into place when returning
it to the retainer to prevent
hood damage. 2. Lower the hood to
approximately 12 in (30 cm)
above the hood release latch
and release it. Check to make
sure the hood is closed and
repeat the process if
necessary.
