Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive
called methylcyclopentadienyl
manganese tricarbonyl (MMT);
ask the attendant where you buy
gasoline whether the fuel contains
MMT. We recommend against
the use of such gasolines. Fuels
containing MMT can reduce spark
plug life and affect emission
control system performance.
The malfunction indicator lamp
might turn on. If this occurs,
return to your dealer for service.Filling the Tank
{WARNING
Fuel vapor burns violently and a
fuel fire can cause bad injuries.
To help avoid injuries to you and
others, read and follow all the
instructions on the fuel pump
island. Turn off the vehicle when
refueling. Do not smoke near
fuel or when refueling the vehicle.
Do not use cellular phones.
Keep sparks, flames, and
smoking materials away from
fuel. Do not leave the fuel pump
unattended when refueling the
vehicle. This is against the law
in some places. Do not re-enter
the vehicle while pumping fuel.
Keep children away from the
fuel pump; never let children
pump fuel.The fuel system on this vehicle
requires a refueling process to
control evaporative emissions.
To refuel the vehicle:
1. Press the fuel door button on
the driver door for one second.
A WAIT TO REFUEL message
displays on the Driver
Information Center.

Driving and Operating 9-61
2. When the READY TO REFUELmessage displays, the fuel
door on the passenger side will
unlock. Push the rearward edge
of the fuel door in and release
to open the door.
3. Turn the fuel cap counterclockwise to remove.
While refueling, hang the fuel
cap tether from the hook on
the inside of the fuel door.
Complete refueling within
30 minutes of pushing the
fuel door button found on the
driver side door. If refueling
more than 30 minutes, push
the fuel door button again. 4. After refueling, reinstall the fuel
cap by turning it clockwise until it
clicks. Close the fuel door.
{WARNING
Fuel can spray out on you
if you open the fuel cap too
quickly. If you spill fuel and then
something ignites it, you could
be badly burned. This spray can
happen if the tank is nearly full,
and is more likely in hot weather.
Open the fuel cap slowly and
wait for any hiss noise to stop.
Then unscrew the cap all the way.
Do not top off or overfill the tank and
wait a few seconds before removing
the nozzle. Clean fuel from painted
surfaces as soon as possible.
See Exterior Care on page 10‑89.
{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.
Notice: 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 might
not fit properly, might cause
the malfunction indicator lamp
to light, and could damage the
fuel tank and emissions system.
See Malfunction Indicator Lamp
on page 5‑21.

Filling a Portable Fuel
Container
{WARNING
Never fill a portable fuel
container while it is in the vehicle.
Static electricity discharge from
the container can ignite the fuel
vapor. You can be badly burned
and the vehicle damaged if this
occurs. To help avoid injury to
you and others:
.Dispense fuel only into
approved containers.
.Do not fill a container while
it is inside a vehicle, in a
vehicle's trunk, pickup bed,
or on any surface other than
the ground.(Continued)
WARNING (Continued)
.Bring the fill nozzle in contact
with the inside of the fill
opening before operating the
nozzle. Contact should be
maintained until the filling
is complete.
.Do not smoke while
pumping fuel.
.Do not use a cellular phone
while pumping fuel.

Doing Your Own
Service Work
{WARNING
Never try to do your own
service on high voltage battery
components. You can be injured
and the vehicle can be damaged
if you try to do your own service
work. Service and repair of these
high voltage battery components
should only be performed by a
trained service technician with
the proper knowledge and tools.
Exposure to high voltage
can cause shock, burns, and
even death. The high voltage
components in the vehicle can
only be serviced by technicians
with special training.(Continued)
WARNING (Continued)
High voltage components are
identified by labels. Do not
remove, open, take apart,
or modify these components.
High voltage cable or wiring has
orange covering. Do not probe,
tamper with, cut, or modify high
voltage cable or wiring.
{WARNING
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
.Be sure you have sufficient
knowledge, experience,
the proper replacement
parts, and tools before
attempting any vehicle
maintenance task.(Continued)
WARNING (Continued)
.Be sure to use the proper
nuts, bolts, and other
fasteners. Metric and
English fasteners can be
easily confused. If the wrong
fasteners are used, parts
can later break or fall off.
You could be hurt.
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
on page 13‑12.
This vehicle has an airbag system.
Before attempting to do your own
service work, see Airbag System
Check on page 3‑40.
