Ultrasonic Parking Assist
If available, this system uses
sensors on the rear bumper to
assist with parking and avoiding
objects while in R (Reverse).
It operates at speeds less than 8 km/h (5 mph). URPA uses audible
beeps to provide distance and
system information.
Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
See
Ultrasonic Parking Assist on
page 9‑40.
Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
There are two accessory power
outlets. One is located under the

Automatic Engine Start/
Stop Feature
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 brake
pedal is applied and the vehicle
comes to a complete stop. When
the brake pedal is released, or the
accelerator pedal is applied, the
engine will restart. The engine will
continue to run until the next
auto stop.
To restart the engine during the auto
stop, release the brake pedal or
press the accelerator pedal. The
engine starts immediately. The
vehicle continues to run until the
next stop.
AUTO STOP on the tachometer
signifies that the engine is in auto
stop mode. SeeTachometer on
page 5‑11 for more information.
A chime will sound when the driver
door is opened while in auto stop mode. Remember to shift to P (Park)
and turn the ignition to LOCK/OFF
before exiting the vehicle.
See
Starting the Engine on
page 9‑19.
Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it into electrical energy.
This energy is then stored in the
vehicle's high voltage battery
system, contributing to increased
fuel efficiency.
The system works whenever the
accelerator pedal is released, and
increases the energy captured as
more brake pedal is applied.
Battery
This vehicle has a standard 12-volt
battery. Refer to the replacement
number on the original battery label
when a new standard 12-volt battery
is needed. Vehicles with eAssist also have a
high voltage battery. Only a trained
service technician with the proper
knowledge and tools should inspect,
test, or replace the high voltage
battery. See your dealer if the high
voltage battery needs service. See
Battery on page 10‑27.
Service
Never try to do your own service on
eAssist components. You can be
injured and the vehicle can be
damaged if you try to do your own
service work. Service and repair of
these high voltage components
should only be performed by a
trained service technician with the
proper knowledge and tools. See
Doing Your Own Service Work on
page 10‑4.

tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
SeeTire Pressure Monitor System
on page 10‑50.
Tire Sealant and
Compressor Kit
This vehicle may come with a spare
tire and tire changing equipment or
a tire sealant and compressor kit.
The kit can be used to temporarily
seal small punctures in the tread
area of the tire. See Tire Sealant
and Compressor Kit (With Pressure
Relief Button) on page 10‑64 orTire
Sealant and Compressor Kit (With
Pressure Deflation Button) on
page 10‑71.
If the vehicle came with a spare tire
and tire changing equipment, see If
a Tire Goes Flat on page 10‑62.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the CHANGE ENGINE
OIL SOON message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN with the engine off.
2. Press the DIC MENU button on the turn signal lever to enter the
Vehicle Information Menu. Use
the thumbwheel to scroll through
the menu items until you reach
REMAINING OIL LIFE.
3. Press the SET/CLR button to reset the oil life at 100%.
4. Turn the ignition to LOCK/OFF.
See Engine Oil Life System on
page 10‑13.

can use either unleaded gasoline or
ethanol fuel containing up to 85%
ethanol (E85). See Fuel E85 (85%
Ethanol) on page 9‑49. For all other
vehicles, use only the unleaded
gasoline described under
Recommended Fuel on page 9‑47.
