It will also illuminate momentarily when
you switch the ignition on to confirm the
lamp is functional. If it does not illuminate
when you switch the ignition on, or begins
to flash at any time, have the system
checked by your authorized dealer.
Parking Lamps
It will illuminate when you switch
the parking lamps on.
Service Engine Soon If the service engine soon
indicator light stays illuminated
after the engine is started, it
indicates that the On Board Diagnostics
system (OBD) has detected a malfunction
of the vehicle emissions control system.
Refer to On board diagnostics (OBD) in
the Fuel and Refueling chapter for more
information about having your vehicle
serviced. See Emission Control System
(page 131).
If the light is blinking, engine misfire is
occurring which could damage your
catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and
deceleration) and have your vehicle
serviced immediately.
Note: Under engine misfire conditions,
excessive exhaust temperatures could
damage the catalytic converter or other
vehicle components.
The service engine soon indicator light
illuminates when the ignition is first turned
on prior to engine start to check the bulb
and to indicate whether the vehicle is ready
for Inspection/Maintenance (I/M) testing. Normally, the service engine soon light will
stay on until the engine is cranked, then
turn itself off if no malfunctions are
present. However, if after 15 seconds the
service engine soon light blinks eight times,
it means that the vehicle is not ready for
I/M testing. See
Emission Control
System (page 131).
Stability Control It will flash when the system is
active. If it remains illuminated
or does not illuminate when you
switch the ignition on, this indicates a
malfunction. During a malfunction the
system will switch off. Have the system
checked by your authorized dealer
immediately. See
Using Stability
Control (page 144).
Stability Control Off It will illuminate when you switch
the system off. It will go out
when you switch the system
back on or when you switch the ignition
off. See
Using Stability Control (page
144).

You may need to cycle the ignition from
off to on several times after refueling
to allow the fuel system to pump the
fuel from the fuel tank to the engine.
On restarting, cranking time will take a
few seconds longer than normal.
• Normally, adding 1.0 gal (3.8 L) of fuel
is enough to restart the engine. If the
vehicle is out of fuel and on a steep
grade, more than
1.0 gal (3.8 L) may
be required.
• The service engine soon indicator may
come on. For more information on the
service engine soon indicator, See
Warning Lamps and Indicators
(page
79).
• For information on calculating DTE
(Distance to empty), See Instrument
Cluster
(page 77).
Refilling With a Portable Fuel
Container WARNINGS
Do not insert the nozzle of portable
fuel containers or aftermarket
funnels into the Easy Fuel
“no cap”
fuel system. This could damage the fuel
system and its seal, and may cause fuel to
run onto the ground instead of filling the
tank, which could result in serious personal
injury. Do not try to pry open or push open
the Easy Fuel
“no cap” fuel system
with foreign objects. This could
damage the fuel system and its seal and
cause injury to you or others. Note:
When filling the vehicle ’s fuel tank
from a portable fuel container, use the
funnel included with the vehicle.
With the Easy Fuel capless fuel system,
use the following directions when filling
from a portable fuel container: 1. Locate the white plastic funnel in the
spare tire compartment.
2. Slowly insert the portable fuel container into the fuel filler opening.
3. Fill the vehicle with fuel from the portable fuel container.
4. When done, clean the funnel or properly dispose of it. You can
purchase extra funnels from your
authorized dealer if you choose to
dispose of the funnel. Do not use
aftermarket funnels. They will not work
with the Easy Fuel system and can
damage it. We have specially designed
the included funnel to work safely with
your vehicle.
REFUELING WARNINGS
Fuel vapor burns violently and a fuel
fire can cause severe injuries.
Read and follow all the instructions
on the pump island.
Turn off your engine when you are
refueling.
Do not smoke if you are near fuel or
refueling your vehicle.
Keep sparks, flames and smoking
materials away from fuel.

If the fuel fill inlet was not properly closed,
a Check Fuel Fill Inlet message may
appear on the instrument cluster.
At the next opportunity, do the following:
1. Stop your vehicle as soon as safely possible and shift the transmission into
park (P).
2. Open the fuel filler door and remove any visible debris from the fuel fill
opening.
3. Insert either the fuel fill nozzle or the fuel fill funnel provided with the vehicle
several times to allow the inlet to close
properly. This will dislodge any debris
preventing the inlet from sealing.
If this action corrects the problem, the
message may not reset immediately. It
may take several driving cycles for the
message to turn off. A driving cycle
consists of an engine start-up (after 4 or
more hours with the engine off) followed
by city or highway driving. Continuing to
drive with the message on may cause the
service engine soon lamp to turn on as
well.
FUEL CONSUMPTION
Your fuel tank's advertised capacity
includes the fuel indicated by your gauge
plus an empty reserve of fuel that remains
after the fuel gauge indicates empty. See
Capacities and Specifications
(page
267).
• The empty reserve makes sure that you
do not run of out fuel until after the
gauge indicates empty.
• Due to the empty reserve, you may not
be able to refuel the full amount of the
advertised capacity of the fuel tank
even when the fuel gauge reads empty.
Note: The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range. Filling the Tank
For consistent results when refueling:
•
Always switch the ignition off before
refueling. If you leave the engine
running, you will get an inaccurate
reading.
• Use the same fill rate
(low-medium-high) each time you fill
the tank.
• Allow no more than two automatic
shut-offs when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first
1000 mi (1,600 km) of driving (this is
your engine ’s break-in period). A more
accurate measurement is obtained after
2000 mi (3,000 km)
to 3000 mi
(5,000 km). Also, fuel expense, frequency
of fill ups or fuel gauge readings are not
accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the fuel tank, record the amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy by dividing miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).

With your vehicle in drive (D), the paddle
shifters provide temporary manual control.
They allow you the ability to shift gears
quickly, without taking your hands off the
steering wheel.
You can achieve extensive manual control
by moving the gearshift lever to the sport
(S) position.
•
Pull and release the right paddle (+)
to upshift.
• Pull and release the left paddle (–) to
downshift. The system determines when temporary
manual control is no longer in use and
returns to automatic control.
Upshift to the recommended shift speeds
according to the following chart:
Upshifts when accelerating (recom-
mended for best fuel economy)
Shift from:15 mph (24 km/h)
1 - 2
25 mph (40 km/h)
2 - 3
40 mph (64 km/h)
3 - 4

The instrument cluster displays your
currently selected gear. The transmission automatically upshifts
if your engine speed is too high or
downshifts if your engine speed is too low.
Note:
The system stays in manual control
until you make another shift button
selection. For example, drive (D).
Note: Engine damage may occur if
excessive engine revving is held without
shifting.
Brake-Shift Interlock WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are
working.
When doing this procedure, you will
be taking your vehicle out of park
which means your vehicle can roll
freely. To avoid unwanted vehicle
movement, always fully set the parking
brake prior to doing this procedure. Use
wheel chocks if appropriate. If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. See your authorized
dealer. Note:
Contact an authorized dealer as soon
as possible if this procedure is used.
Note: For some markets, this feature will
be disabled.
Use the brake shift interlock lever to move
the gearshift lever from the park position
in the event of an electrical malfunction or
if your vehicle has a dead battery.
Apply the parking brake and switch the
ignition off before performing this
procedure.
