Contact your dealer/retailer, if
the light does not come on or if it
stays on.
Traction Control System
(TCS) Warning Light
This warning light comes on briefly
when the ignition is turned to
ON/RUN.
It also comes on when the Traction
Control System is turned off by
pressing the TRAC OFF button.
See Traction Control System (TCS)
on page 8-33 for more information. If it stays on or comes on while
driving, there is a problem with the
Traction Control System (TCS),
contact your dealer/retailer.
Tire Pressure Light
This light should come on briefly as
the engine is started.
If there is a tire with low tire
pressure, the light will stay on
or come back on.
See
Tire Pressure Monitor
Operation on page 9-52 for more
information.
Engine Oil Pressure
Light
{CAUTION
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine
oil maintenance can damage
the engine. The repairs would
not be covered by the vehicle
warranty. Always follow the
maintenance schedule in this
manual for changing engine oil.
The oil pressure light should come
on briefly as the engine is started. If it
does not come on have the vehicle
serviced by your dealer/retailer.
Instruments and Controls 4-19
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
Low Fuel Warning Light
This light, on the fuel gage, comes
on when the fuel tank is low on
fuel. To turn if off, add fuel to the
fuel tank.
Security Light
For information regarding this light
and the vehicle’s security system,
seeVehicle Security on page 1-7 .
High-Beam on Light
The highbeam on light comes on
when the high-beam headlamps are
in use.
SeeHeadlamp High/Low-Beam
Changer on page 5-2 for more
information.
Fog Lamp Light
The fog lamp light comes on when
the fog lamps are in use.
The light goes out when the fog
lamps are turned off. See Fog
Lamps on page 5-4 for more
information.
Lamps on Reminder
This light comes on whenever the
headlights are on.
See Exterior Lamp Controls on
page 5-1 for more information.

4-20 Instruments and Controls
Fuels in Foreign
Countries
If you plan on driving in another
country outside the United States
or Canada, the proper fuel might
be hard to find. Never use leaded
gasoline or any other fuel not
recommended in the previous text
on fuel. Costly repairs caused by
use of improper fuel would not be
covered by the vehicle warranty.
To check the fuel availability, ask an
auto club, or contact a major oil
company that does business in the
country where you will be driving.
Fuel Additives
To provide cleaner air, all gasolines
in the United States are now required
to contain additives that help prevent
engine and fuel system deposits
from forming, allowing the emission
control system to work properly.
In most cases, you should not have
to add anything to the fuel. However,
some gasolines contain only the
minimum amount of additive required
to meet U.S. Environmental
Protection Agency regulations.
To help keep fuel injectors and
intake valves clean, or if the vehicle
experiences problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline. Look for the
TOP TIER label on the fuel pump to
ensure gasoline meets enhanced
detergency standards developed
by the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found
at www.toptiergas.com.For customers who do not use
TOP TIER Detergent Gasoline
regularly, one bottle of GM Fuel
System Treatment PLUS, added to
the fuel tank at every engine oil
change, can help clean deposits
from fuel injectors and intake valves.
GM Fuel System Treatment
PLUS is the only gasoline additive
recommended by General Motors.
It is available at your dealer/retailer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed for
those fuels.
8-40 Driving and Operating
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer won’t strike soft shoulders,
curbs, road signs, trees or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes or stopping. When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. For this reason you may
think other drivers are seeing the
signal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the transmission
is not shifted down, the brakes
might have to be used so much that
they would get hot and no longer
work well.
Vehicles with an automatic
transmission can tow in D (Drive).
Shift the transmission to a lower gear
if the transmission shifts too often
under heavy loads and/or hilly
conditions. For vehicles with a
manual transmission, it is better
not to use the highest gear.When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at a
lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. For vehicles with manual
transmissions, let the engine run
while parked, preferably on level
ground, with the transmission out of
gear and the parking brake applied,
for a few minutes before turning the
engine off. If the overheat warning
comes on, see
Engine Overheating
on page 9-23.
8-46 Driving and Operating
Parking on Hills
{CAUTION
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet for vehicles
with an automatic transmission,
or into gear for vehicles with a
manual transmission. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park) for vehicles
with an automatic transmission
or into gear for vehicles with
a manual transmission.
5. Release the brake pedal.
Leaving After Parking on
a Hill
1. Apply and hold the brake pedal while you:
•start the engine,
•shift into a gear, and
•release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See this
manual’s Maintenance Schedule or
Index for more information. Things
that are especially important in trailer
operation are automatic transmission
fluid, engine oil, axle lubricant, belts,
cooling system and brake system.
It is a good idea to inspect these
before and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
on page 9-23.
