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
battery is low, a Driver
Information Center (DIC)
message will display. See Key and
Lock Messages 0 145 and Remote
Keyless Entry (RKE) System
Operation 0 29.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
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. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts, release
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
Warning
Exiting the vehicle without first
shifting into P (Park) may cause the
vehicle to move. You or others may
be injured. Because the vehicle has
the auto engine stop/start feature,
DRIVING AND OPERATING
Warning (Continued)
the vehicle's engine might seem to
be shut off; however, once the brake
pedal is released, the engine will
start up again.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before exiting
the vehicle.
The vehicle has a fuel saving stop/
start system to shut off the engine
and help conserve fuel.
Auto Engine Stop/Start
When the brakes are applied and the
vehicle is at a complete stop, the
engine may turn off. When stopped,
the tachometer may point to AUTO
STOP, or the Auto Stop light may
come on in the instrument cluster. See
Tachometer 0 121 and Auto Stop Mode
(Uplevel Cluster) 0 134. When the
brake pedal is released or the
accelerator pedal is pressed, the
engine may restart.
