Driving at Night
Night driving is more dangerous than day driving
because some drivers are likely to be impaired —by
alcohol or drugs, with night vision problems, or by
fatigue.
Night driving tips include:
.Drive defensively.
.Do not drink and drive.
.Reduce headlamp glare by adjusting the inside
rearview mirror.
.Slow down and keep more space between you and
other vehicles because headlamps can only light
up so much road ahead.
.Watch for animals.
.When tired, pull off the road.
.Do not wear sunglasses.
.Avoid staring directly into approaching headlamps.
.Keep the windshield and all glass on your vehicle
clean —inside and out.
.Keep your eyes moving, especially during turns
or curves.
No one can see as well at night as in the daytime.
But, as we get older, these differences increase.
A 50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.
Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction and
affect your ability to stop and accelerate. Always drive
slower in these types of driving conditions and avoid
driving through large puddles and deep‐standing or
flowing water.
{WARNING:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of
the vehicle.
After driving through a large puddle of water or a
car/vehicle wash, lightly apply the brake pedal
until the brakes work normally.
Flowing or rushing water creates strong forces.
Driving through flowing water could cause your
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.
5-22

TheAntilock Brake System (ABS)on page 5‑5improves vehicle stability during hard stops on a
slippery roads, but apply the brakes sooner than when
on dry pavement.
Allow greater following distance on any slippery road
and watch for slippery spots. Icy patches can occur on
otherwise clear roads in shaded areas. The surface
of a curve or an overpass can remain icy when the
surrounding roads are clear. Avoid sudden steering
maneuvers and braking while on ice.
Turn off cruise control, if equipped, on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a serious situation.
Stay with the vehicle unless there is help nearby.
If possible, use the Roadside Assistance Program
on
page 8‑7. To get help and keep everyone in the
vehicle safe:
.Turn on the Hazard Warning Flasherson
page 4‑3.
.Tie a red cloth to an outside mirror.
{WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which 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 (two inches) 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 vehicle and
set the fan speed to the highest setting.
See Climate Control System in the Index.

Gasoline Octane
If the vehicle has the 6.2L V8 engine (VIN Code W), use
premium unleaded gasoline with a posted octane rating
of 91 or higher. You can also use regular unleaded
gasoline rated at 87 octane or higher, but the vehicle's
acceleration could be slightly reduced, and a slight
audible knocking noise, commonly referred to as spark
knock, might be heard. If the octane is less than 87,
a heavy knocking noise might be heard when driving.
If this occurs, use a gasoline rated at 87 octane or
higher as soon as possible. Otherwise, you could
damage the engine. If heavy knocking is heard when
using gasoline rated at 87 octane or higher, the engine
needs service.
If the vehicle has the 6.2L V8 engine (VIN Code T)
or the 7.0L V8 engine (VIN Code E), use premium
unleaded gasoline with a posted octane rating of 91
or higher. For best performance, use premium unleaded
gasoline with a posted octane rating of 93. In an
emergency, you can use regular unleaded gasoline
with an octane rating of 87 or higher. If 87 octane fuel is
used, do not perform any aggressive driving maneuvers
such as wide open throttle applications. You might also
hear audible spark knock during acceleration. Refill the
tank with premium fuel as soon as possible to avoid
damaging the engine. If heavy knocking is heard when
using gasoline rated at 91 octane or higher, the engine
needs service.
Gasoline Specifications
At a minimum, gasoline should meet ASTM
specification D 4814 in the United States or
CAN/CGSB‐3.5 or 3.511 in Canada. Some gasolines
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT).
We recommend against the use of gasolines containing
MMT. See Additives
on page 6‑8for additional
information.
California Fuel
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 might fail
a smog‐check test. See Malfunction Indicator Lamp
on
page 4‑41. If this occurs, return to your authorized
dealer/retailer for diagnosis. If it is determined that the
condition is caused by the type of fuel used, repairs
might not be covered by the vehicle warranty.

What to Do with Used Oil
Used engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good hand
cleaner. Wash or properly dispose of clothing or rags
containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it in
the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Recycle it by taking it to a
place that collects used oil.
Engine Air Cleaner/Filter
See Engine Compartment Overviewon page 6‑14for
the location of the engine air cleaner/filter.
Notice: If you spray water into the engine air
cleaner/filter intake and water enters the engine
air cleaner/filter housing, you could damage your
vehicle's engine. The repairs would not be covered
by your warranty. Do not spray water into the
engine air cleaner/filter intake and/or housing. If you are cleaning the vehicle with the hood open, take
care not to spray water directly near the filter opening of
the air cleaner, as shown in the illustration, as this could
damage the vehicle's engine.
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the Maintenance
II
intervals and replace them at the first oil change after
each 80 000 km (50,000 mile) interval. See Scheduled
Maintenance
on page 7‑3for more information. If you
are driving in dusty/dirty conditions, inspect the filter at
each engine oil change.
How to Inspect the Engine Air Cleaner/
Filter
To inspect the air cleaner/filter, remove the filter from
the vehicle and lightly shake the filter to release loose
dust and dirt. If the filter remains caked with dirt, a new
filter is required.
6-27

If No Steam Is Coming From Your
Engine
If an engine overheat warning is displayed but no steam
can be seen or heard, the problem may not be too
serious. Sometimes the engine can get a little too hot
when the vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayed with no sign of
steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to N (Neutral) while stopped. If it is safe to do so, pull off the road, shift to
P (Park) or N (Neutral) and let the engine idle. If the temperature overheat gauge is no longer in
the overheat zone or an overheat warning no longer
displays, the vehicle can be driven. Continue to drive
the vehicle slow for about 10 minutes. Keep a safe
vehicle distance from the car in front of you. If the
warning does not come back on, continue to drive
normally.
If the warning continues, pull over, stop, and park the
vehicle right away.
If there is no sign of steam, idle the engine for
three minutes while parked. If the warning is still
displayed, turn off the engine until it cools down.
Also, see
“Overheated Engine Protection Operating
Mode” next in this section.
6-40

Overheated Engine Protection
Operating Mode
This emergency operating mode lets the vehicle
be driven to a safe place, up to 50 miles (80 km),
in an emergency situation. If an overheated engine
condition exists and the messages COOLANT OVER
TEMPERATURE and REDUCED ENGINE POWER
are displayed, along with the check engine light, an
overheat protection mode which alternates firing groups
of cylinders helps prevent engine damage. In this
mode, there is a significant loss in power and engine
performance.
Driving extended distances in the overheat protection
mode should be avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life system. See Engine Oil
on
page 6‑19.
Power Steering Fluid
See Engine Compartment
Overviewon page 6‑14for reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
