9-22 Driving and Operating
eAssist Automatic Engine
Start/Stop
{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 automatic engine
start/stop feature, 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.
Vehicles with eAssist have an
automatic engine start/stop feature.
After the engine is started and has
reached operating temperature, the
auto stop feature may cause the
engine to turn off when the brakes are applied and the vehicle comes
to a complete stop. The vehicle
may remain in auto stop for up to
two minutes. When the brake is
released or the accelerator pedal is
applied, the engine will start. The
engine will continue to run until the
next auto stop.
AUTO STOP on the tachometer
signifies that the engine is in auto
stop mode. See
Tachometer on
page 5‑11 for more information.
When the vehicle is turned off, the
tachometer will move to OFF. If the
driver door is opened while in auto
stop mode, a chime will sound.
To restart the engine during auto
stop, release the brake pedal or
press the accelerator pedal. The
engine starts immediately. The
vehicle continues to run until the
next stop.
There are several conditions which
may prevent an auto stop or cause
an auto start. The Engine Will Remain
Running When:
.The engine, transmission,
or high voltage battery is not
warmed up yet.
.The outside temperature is less
than
−20°C (−4°F).
.The air conditioning or defrost
system need the compressor to
maintain vehicle comfort. See
Dual Automatic Climate Control
System on page 8‑3 for more
information.
.The shift lever is in P (Park),
N (Neutral), R (Reverse),
or M (Manual Mode).
.The high voltage battery pack
charge is low.
.The 12‐volt vehicle battery
charge is low, or loads are high.
.The hood is not fully closed.
.Brake pedal pressure is high.
.If the MIL is on, auto stop may
be prevented.

Driving and Operating 9-23
The Engine Will Restart When:
.The brake pedal is released.
.The accelerator pedal is applied.
.Shifting out of D (Drive) to any
other gear.
.If eco air conditioning is
selected, the duration of the auto
stop will depend on the outside
temperature. This economy
mode improves fuel economy by
limiting the effects of the air
conditioning. The warmer it is
outside, the shorter the time
before the engine is restarted to
provide cabin cooling.
.The climate control system is
turned from off to normal air
conditioning or defrost. SeeDual
Automatic Climate Control
System on page 8‑3 for more
information.
.The engine is required to run for
either heater or climate control
performance. See Dual
Automatic Climate Control
System on page 8‑3 for more
information.
.The high voltage battery pack
charge is low and requires
recharging.
.Auto stop time is greater than
two minutes.
.The hood is opened.
Engine Heater
The engine coolant 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 coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above −18°C (0°F).

9-24 Driving and Operating
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap theelectrical cord.
The electrical cord is located on
the passenger side of the engine
compartment, between the
fender and the air cleaner.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a fire. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and store the
cord as it was before to keep it
away from moving engine parts.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.
Retained Accessory
Power (RAP)
These vehicle accessories can be
used for up to 10 minutes after the
engine is turned off:

Driving and Operating 9-47
SeeFuel E85 (85% Ethanol) on
page 9‑49. For all other vehicles,
use only the unleaded gasoline
described under Recommended
Fuel on page 9‑47.
Recommended Fuel
If the vehicle has the 2.4L L4 engine
(VIN Code K) or the 2.4L L4 engine
(VIN Code R), use regular unleaded
gasoline with a posted octane rating
of 87 or higher. If the octane rating
is less than 87, an audible knocking
noise, commonly referred to as
spark knock, might be heard when
driving. If this occurs, use a
gasoline rated at 87 octane or
higher as soon as possible. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.
If the vehicle has the 2.0L L4 engine
(VIN Code V), use premium
unleaded gasoline with a posted
octane rating of 91 or higher. You
can also use regular unleaded
gasoline rated at 87 octane or higher, but the vehicle's acceleration
could be slightly reduced, and a
slight audible knocking noise,
commonly referred to as spark
knock, might be heard. If the octane
is less than 87, a heavy knocking
noise might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. Otherwise, you could
damage the engine. If heavy
knocking is heard when using
gasoline rated at 87 octane or
higher, the engine needs service.
Gasoline Specifications
(U.S. and Canada Only)
At a minimum, gasoline should
meet ASTM specification D 4814
in the United States or CAN/
CGSB‐3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines containing MMT. See
Fuel Additives
on page 9‑48 for additional
information.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test.
See Malfunction Indicator Lamp on
page 5‑15. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.
