9-6 Driving and Operating Warning (Continued)Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet. Other Rainy Weather Tips Besides slowing down, other wet
weather driving tips include: .
Allow extra following distance. .
Pass with caution. .
Keep windshield wiping
equipment in good shape. .
Keep the windshield washer fluid
reservoir filled. .
Have good tires with proper
tread depth. See Tires on
page 10-26 . .
Turn off cruise control.
Hill and Mountain Roads Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include: .
Keep the vehicle serviced and in
good shape. .
Check all fluid levels and brakes,
tires, cooling system, and
transmission. .
Shift to a lower gear when going
down steep or long hills.
{ WarningUsing the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{ Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.

9-8 Driving and Operating Warning (Continued)cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in the snow: .
Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe. .
Check again from time to
time to be sure snow does
not collect there. .
Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air. .
Fully open the air outlets on
or under the instrument
panel. .
Adjust the climate control
system to a setting that
circulates the air inside the
(Continued) Warning (Continued) vehicle and set the fan speed
to the highest setting. See
“ Climate Control Systems. ”
For more information about
carbon monoxide, see Engine
Exhaust on page 9-17 .
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel. If the Vehicle Is Stuck Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See Traction
Control/Electronic Stability Control
on page 9-25 .
{ WarningIf the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).

Driving and Operating 9-21Shift Lock Release
If the battery is discharged, the shift
lever may not be moved from the
P (Park) position even with the foot
brake pedal depressed.
To move the shift lever, perform the
following procedure:
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 on page 5-15 .
Use the Overdrive off mode when
you need improved engine braking.
To turn off the Overdrive off mode,
push the O/D OFF switch again.
The indicator light will turn off.

9-22 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, depress
the accelerator pedal to the floor.
This shifts the transmission down
into a lower gear, depending on the
vehicle speed.
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 MIL may come on to indicate
the fail-safe mode is activated. See
Malfunction Indicator Lamp on
page 5-11 . 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.
{ WarningWhen 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. Brakes Antilock Brake
System (ABS)
{ Warning .
The ABS is a sophisticated
device, but it cannot prevent
accidents resulting from
careless or dangerous driving
techniques. It can help
maintain vehicle control
during braking on slippery
surfaces. Remember that
stopping distances on
slippery surfaces will be
longer than on normal
surfaces even with ABS.
Stopping distances may also
be longer on rough, gravel or
snow covered roads, or if you
are using tire chains. Always
maintain a safe distance from

9-38 Driving and Operating 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 might
be affected. The malfunction
indicator lamp could turn on and the
vehicle may not pass a smog-check test. See Malfunction Indicator
Lamp on page 5-11 . 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 If planning to drive in countries
outside the U.S. or Canada, the
proper fuel might be hard to find.
Check regional auto club or fuel
retail brand websites for availability
in the country where driving. Never
use leaded gasoline, fuel containing
methanol, manganese, or any other
fuel not recommended. Costly
repairs caused by use of improper
fuel would not be covered by the
vehicle warranty. Fuel Additives To keep fuel systems clean, TOP
TIER Detergent Gasoline is
recommended. See Fuel on
page 9-37 .
If TOP TIER Detergent Gasoline is
not available, one bottle of Fuel
System Treatment PLUS added to
the fuel tank at every engine oil
change can help. Fuel System
Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Do not use additives with E85 or
FlexFuel.

10-4 Vehicle Care Warning (Continued)Your vehicle ’ s warranty may not
cover damage resulting from
alterations, modifications,
installation of non-approved
accessories, or improper
installation of accessories. Refer
to your Warranty Information
Booklet for complete details.
Variable Voltage Control System
{ Caution .
Do not ground accessories
directly to the battery
terminal. Doing so will bypass
the variable voltage control
system and the vehicle
battery many not charge
completely. .
Use electrical accessories
with the engine running to
avoid discharging the vehicle
battery.
Your vehicle is equipped with a
variable voltage control system.
This system measures the amount
of electrical discharge from the
battery and controls voltage
generated by the generator. The
current sensor is located near the
battery along the negative battery
cable. If you add electrical
accessories to your vehicle, be sure
to ground them to a suitable body
ground such as the frame or engine
block area. Vehicle Checks Doing Your Own
Service Work
{ WarningIt can be dangerous to work on
your vehicle if you do not have
the proper knowledge, service
manual, tools, or parts. Always
follow owner manual procedures
and consult the service manual
for your vehicle before doing any
service work.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see Service
Publications Ordering Information
