Warning Lamps
Malfunction Indicator Lamp If it illuminates when the engine is
running, the on-board diagnostics
system is detecting a malfunction
of the vehicle emission control system.
If it flashes, engine misfire could be
occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Avoid heavy acceleration and deceleration,
and have your vehicle checked as soon as
possible. Powertrain Warning Lamp If it illuminates when the engine is
running, this indicates a powertrain
or four-wheel drive fault. If it
flashes when you are driving, immediately
reduce the vehicle speed. Avoid heavy
acceleration and deceleration, and have your
vehicle checked as soon as possible.
If both lamps illuminate when the engine is
running, stop your vehicle as soon as it is
safe to do so. Continuing to drive your
vehicle could cause reduced power or the
engine to stop. Switch the ignition off and
attempt to restart the engine. Have your
vehicle checked as soon as possible.

Frequently Asked Questions
Why is the engine idle speed high when I
am starting the engine?
The speed at which the engine idles
immediately after starting is optimized
to minimize vehicle emissions and
maximize cabin comfort and fuel
economy.
Why does the engine not crank? You can only attempt to start the engine
for a limited amount of time before the
starting system temporarily disables. If
you exceed the starting time limit, a
message may appear and you cannot
attempt to start the engine for at least
15 minutes. Why do I experience different driving
characteristics?
If you disconnect the battery, your
vehicle may exhibit some unusual
driving characteristics for approximately
5 mi (8 km) after you reconnect it. This
is because the engine management
system must realign itself with the
engine. You can disregard any unusual
driving characteristics during this period.
Why can I not start the engine? If you cannot start the engine after 3
attempts, wait 10 seconds and do the
following:
1. Fully press the brake pedal.
Note: Make sure that the parking brake is
applied.
Note: Make sure that the transmission is in
park (P) or neutral (N).
2. Fully press the accelerator pedal and hold it there.
3. Press the push button ignition switch.
Note: The engine cranks for a short period
of time and then it stops. 4. Release the accelerator pedal.
5. Press the push button ignition switch.
Why does the system not detect a passive
key?
If the system does not detect a passive
key and you are unable to start the
engine, insert the passive key into the
backup position and press the push
button ignition switch to start the
engine. See Accessing the Passive Key
Backup Position
(page 190).

FUEL AND REFUELING
PRECAUTIONS
WARNING: Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire. WARNING:
The fuel system may be
under pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel until
the sound stops. Otherwise, fuel may spray
out, which could cause serious personal
injury. WARNING:
Fuels can cause serious
injury or death if misused or mishandled. WARNING:
Fuel may contain
benzene, which is a cancer-causing agent. WARNING:
When refueling always
shut the engine off and never allow sparks
or open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. WARNING:
Read and follow all the
instructions on the pump island.
Follow these guidelines when refueling:
• Extinguish all smoking materials and any
open flames before refueling your
vehicle.
• Switch the engine off before refueling.
• Automotive fuels can be harmful or fatal
if swallowed. Fuel is highly toxic and if
swallowed can cause death or permanent
injury. If fuel is swallowed immediately
call a physician, even if no symptoms are
immediately apparent. The toxic effects
of fuel may not be apparent for hours. •
Avoid inhaling fuel vapors. Inhaling fuel
vapor can lead to eye and respiratory
tract irritation. In severe cases, excessive
or prolonged breathing of fuel vapor can
cause serious illness and permanent
injury.
• Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses, if worn, flush with
water for 15 minutes and seek medical
attention. Failure to seek proper medical
attention could lead to permanent injury.
• Fuels can be harmful if absorbed through
the skin. If you splash fuel on your skin,
clothing or both, promptly remove
contaminated clothing and thoroughly
wash your skin with soap and water.
Repeated or prolonged skin contact
causes skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram for
the treatment of alcoholism. Breathing
fuel vapors could cause an adverse
reaction, serious personal injury or
sickness. Immediately call a physician if
you experience any adverse reactions.
