eAssist Features

eAssist®Overview

If the vehicle has eAssist, there are several additional features that contribute to increased efficiency.
Vehicles with eAssist have an automatic engine start/stop feature. This feature saves fuel by shutting the engine off when the vehicle is stopped. When the engine shuts off automatically, all the accessories will continue to operate normally. In very hot or cold conditions, the engine will only shut off automatically part of the time. See Starting the Engine on page 9-18.
There are two air conditioning settings available. The comfort setting maximizes cabin comfort.
The eco setting maximizes efficiency allowing more frequent, and longer engine stops than the comfort setting. See Dual Automatic
Climate Control System on page 8-1.
This vehicle has a Hill Start Assist (HSA) feature, which may be useful when the vehicle is stopped on a grade. See Hill Start Assist (HSA) on page 9-34.
Vehicles with eAssist have a slightly different instrument cluster, which includes an AUTO STOP indicator on the tachometer. See Instrument
Cluster (Uplevel Cluster) on page 5-12 or Instrument Cluster (Base Level Cluster) on page 5-8.
The eAssist system uses a high voltage battery, which is cooled with air drawn from the vehicle interior.
The cold air intake for the battery is located behind the rear seat, on the filler panel. Do not cover the intake. See Battery on page 10-26.

High Voltage Safety Information

Vehicles with eAssist have a standard 12-volt battery and 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.

1-20 In Brief
In emergency situations, first responders can cut the two clearly labeled cut points in the engine compartment to disable the high voltage battery and air bag systems — do not cut the high voltage cable.

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. See Tachometer on page 5-15 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 9-18.

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 10-26.

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 10-3.

Tire Pressure Monitor

This vehicle may have a Tire Pressure Monitor System (TPMS).
The low tire pressure warning light alerts to a significant loss in pressure of one of the vehicle's tires. If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the Tire and Loading Information label. See Vehicle Load Limits on page 9-10. The warning light will remain on until the tire pressure is corrected.

1-22 In Brief
The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. This may be an early indicator that the 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.
See Tire Pressure Monitor System on page 10-50.

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. Using the DIC controls on the right side of the steering wheel, display REMAINING OIL LIFE on the DIC. See Driver
Information Center (DIC) (Base Level Cluster) on page 5-32 or Driver Information Center (DIC) (Uplevel Cluster) on page 5-35.
When remaining oil life is low, the CHANGE ENGINE OIL SOON message will appear on the display. See Engine Oil Messages on page 5-41.
2. Press
See Engine Oil Life System on page 10-13.
V on the DIC controls and
hold down for a few seconds to clear the CHANGE ENGINE OIL SOON message and reset the oil life at 100%.
Be careful not to reset the oil life display accidentally at any time other than after the oil is changed. It cannot be reset accurately until the next oil change.

E85 or FlexFuel

Vehicles with a yellow fuel cap can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85). See E85 or FlexFuel on page 9-61. For all other vehicles, use only the unleaded gasoline described under Fuel on page 9-59.

Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible.
.
Avoid fast starts and accelerate smoothly.
.
Brake gradually and avoid abrupt stops.
.
Avoid idling the engine for long periods of time.
.
When road and weather conditions are appropriate, use cruise control.
