2. Turn the key to position III to start the
engine.
3. When the engine starts, release the brake pedal.
Do not crank the engine for more than 10
seconds as starter damage may occur. If
the engine does not start, switch the
ignition off and wait 30 seconds before
trying again.
Vehicles with Keyless Start
Note: Do not touch the accelerator pedal.
Note: If you press the push button ignition
switch again prior to the engine starting, the

1. Fully press the brake pedal.
2. Fully press the accelerator pedal and hold it there.
3. Start the engine.
Stopping the Engine When Your
Vehicle is Stationary
1. When your vehicle has stopped, shift into park (P) and switch the ignition
off.
2. Apply the parking brake. Stopping the Engine When Your
Vehicle is Moving WARNING:
Switching off the
engine when your vehicle is still moving
results in a significant decrease in
braking assistance. Higher effort is
required to apply the brakes and to stop
your vehicle. A significant decrease in
steering assistance could also occur. The
steering does not lock, but higher effort
could be required to steer your vehicle.
When you switch the ignition off, some
electrical circuits, for example airbags,
also turn off. If you unintentionally switch
the ignition off, shift into neutral (N) and
restart the engine.
1. Put the transmission into neutral (N) and use the brakes to bring your vehicle
to a safe stop.
2. When your vehicle has stopped, shift into park (P) and switch the ignition
off.
3. Apply the parking brake.
Automatic Engine Shutdown
If your vehicle has a keyless ignition, it has
a feature that shuts down the engine if it
has been idling for an extended period of
time. The ignition also turns off in order to
save battery power. Before the engine
shuts down, a message appears in the
information display showing a timer
counting down from 30 seconds. If you do
not intervene within 30 seconds, the engine
shuts down. Another message appears in
the information display to inform you that
the engine has shut down in order to save
fuel. Start your vehicle as you normally do.

Cold Weather Starting (Flexible
Fuel Vehicles Only)
The starting characteristics of all grades
of E85 ethanol make it unsuitable for use
when ambient temperatures fall below
0°F (-18°C). Consult your fuel distributor
for the availability of winter grade ethanol.
As the outside temperature approaches
freezing, ethanol fuel distributors should
supply winter grade ethanol, the same as
with unleaded gasoline.
If summer grade ethanol is used in cold
weather conditions, 0°F (-18°C), you may
experience increased cranking times, rough
idle or hesitation until the engine has
warmed up.
You may experience a decrease in
performance when the engine is cold when
operating on E85 ethanol.
Do not use starting fluid such as ether in
the air intake system. Such fluid could
cause immediate explosive damage to the
engine and possible personal injury.
If you should experience cold weather
starting problems on E85 ethanol, and
neither an alternative brand of E85 ethanol
nor an engine block heater is available, the
addition of unleaded gasoline to your tank
improves cold starting performance. Your
vehicle is designed to operate on E85
ethanol alone, unleaded gasoline alone, or
any mixture of the two.
If the Engine Fails to Start Using the
Preceding Instructions (Flexible Fuel
Vehicles Only)
1. Press the accelerator pedal down one-third to one-half of its travel, and
then crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speed
increases. If the engine still does not
start, repeat Step 1. Guarding Against Exhaust Fumes WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the
following:
• Open the windows at least
1 in
(2.5 cm).
• Set your climate control to outside air.
STARTING A DIESEL ENGINE -
6.7L DIESEL
Read all starting instructions carefully
before you start your vehicle.
For temperatures below
32°F (0°C), the
use of the correct grade engine oil is
essential for proper operation. Refer to
engine oil specifications for more
information. See
Engine Oil Capacity
and Specification (page 449).
Your vehicle may have a cold weather
starting strategy that prevents severe
engine damage by assisting in engine
lubrication warm-up. In extremely cold
ambient temperatures, this strategy
activates and prevents the accelerator
pedal from being used for 30 seconds after
you start your vehicle. A message appears
in the information display as your vehicle
warms up. By not allowing the accelerator
pedal to be used, the engine oil is allowed
to properly lubricate the bearings
