To start the engine, the transmission must be in PARK or
NEUTRAL. From any ignition state, press and hold the
brake pedal while pressing the ENGINE START/STOP
button. The system takes over and attempts to start the
vehicle. If the vehicle fails to start, the starter will
disengage automatically after 10 seconds. If you wish to
stop the cranking of the engine prior to the engine
starting, press the button again.
Using Fob With Integrated Key (Tip Start)
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or depressing the
accelerator pedal.
Do not press the accelerator. Use the Fob with Integrated
Key to briefly turn the ignition switch to the START
position and release it as soon as the starter engages. The
starter motor will continue to run, and it will disengage
automatically when the engine is running. If the engine
fails to start, the starter will disengage automatically in
10 seconds. If this occurs, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then repeat the
normal starting procedure.
To Turn Off The Engine Using ENGINE

for two seconds and the ignition state changes to ACCES-
SORY (ACC). Regardless if the ignition state changes to
ACCESSORY (ACC) or OFF, the engine is shut off.

an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
