Caution
If you add electrical parts or
accessories, you could
change the way the engine
operates. Any resulting
damage would not be
covered by the vehicle
warranty. See Add-On
Electrical Equipment0325.
To start the vehicle: 1. With the Keyless Access system, the remote key
must be in the vehicle.
Press ENGINE START/
STOP with the brake pedal
applied. When the engine
begins cranking, let go of
the button. The idle speed
will go down as the engine
warms up. Do not race the
engine immediately after
starting it.
If the remote key is not in
the vehicle, if there is
interference, or if the
remote key battery is low,
a Driver Information Center (DIC) message will
display. See Remote Key
Operation
09.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
immediately after cranking
has ended, can overheat and
damage the cranking motor,
and drain the battery. Wait
at least 15 seconds between
each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold
weather (below −18 °C or
0 °F), it could be flooded
with too much gasoline.
Try pushing the
accelerator pedal all the
way to the floor and hold it
there, then press ENGINE
START/STOP for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow the cranking motor to cool
down. When the engine
starts, let go of the button
and the accelerator. If the
vehicle starts briefly but
then stops again, do the
same thing. This clears the
extra gasoline from the
engine. Do not race the
engine immediately after
starting it. Operate the
engine and transmission
gently until the oil warms
up and lubricates all
moving parts.
Stop/Start System
The Stop/Start system will
shut off the engine to help
conserve fuel. It has
components designed for the
increased number of starts.
{Warning
The automatic engine Stop/
Start feature causes the
engine to shut off while the
vehicle is still on. Do not exit
