Starting and Stopping the Engine
3. With the key in this position, press the
brake pedal (automatic transmission)
or clutch pedal (manual transmission),
then the START button to switch the
ignition on and start your vehicle.
Fast Restart
The fast restart feature allows you to
restart the engine within 20 seconds of
switching it off, even if a valid key is not
present.
Within 20 seconds of switching the engine
off, press the brake pedal (automatic
transmission) or clutch pedal (manual
transmission) and press the button. After
20 seconds have expired, you can no
longer restart the engine without the key
present inside your vehicle.
Once the engine has started, it remains
running until you press the button, even if
the system does not detect a valid key. If
you open and close a door while the engine
is running, the system searches for a valid
key. You cannot restart the engine if the
system does not detect a valid key within
20 seconds.
Failure to Start
If you cannot start the engine after three
attempts, wait 10 seconds and follow this
procedure:
1. If your vehicle is equipped with an
automatic transmission, fully press the
brake pedal. If your vehicle is equipped
with a manual transmission, fully press
the clutch pedal and apply the
handbrake.
2. Move the transmission selector lever
to park (P) (automatic transmission)
or neutral (manual transmission).
3. Fully press the accelerator pedal and
hold it there.
4. Start the engine.

Automatic Engine Shutdown
Your vehicle is equipped with a feature that
automatically shuts down the engine if it
has been idling for an extended period. 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.
Automatic Engine Shutdown Override
Note: You cannot permanently switch off
the automatic engine shutdown feature.
When you switch it off temporarily, it turns
on at the next ignition cycle.
You can stop the engine shutdown, or reset
the timer, at any point before the
30-second countdown has expired by
doing any of the following:
• You can reset the timer by interacting
with your vehicle (such as pressing the
brake pedal or accelerator pedal).
• You can temporarily switch off the
shutdown feature any time the ignition
is on (for the current ignition cycle
only). Use the information display to
do so. See Information Displays
(page 64).
• During the countdown before engine
shutdown, you are prompted to press
OK or RESET (depending on your type
of information display) to temporarily
switch the feature off (for the current
ignition cycle only).
Stopping the Engine When Your
Vehicle is Stationary
