DRIVING AND OPERATING 183
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 Equipment0230.
Starting Procedure 1. With the Keyless Access system, the RKE transmitter must be in
the vehicle. Press the ENGINE
START/STOP button with the
brake pedal applied. When the
engine begins cranking, let go of
the button.
The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it.
If the RKE transmitter is not in
the vehicle, if there is
interference, or if the RKE
transmitter battery is low, the
Driver Information Center (DIC)
will display a message.
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 holding it there
as you 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.
Engine Heater
{Warning
Do not plug in the engine block
heater while the vehicle is parked in
a garage or under a carport.
Property damage or personal injury
may result. Always park the vehicle
in a clear open area away from
buildings or structures.
The engine heater, if available, can
help in cold weather conditions at or
below −18 °C (0 °F) for easier starting
and better fuel economy during
engine warm-up. Plug in the engine
heater at least four hours before
starting the vehicle. An internal
