SeeSunroof 047.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 0178.
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 0157. 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) 0191.
Vehicles with eAssist have a slightly
different instrument cluster, which
includes an AUTO STOP indicator
on the tachometer. See Instrument
Cluster (Base Level Cluster) 0104
or Instrument Cluster (Uplevel
Cluster) 0108.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.

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 Limits0171. The
warning light will remain on until the
tire pressure is corrected.
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 0262.
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) 0125 orDriver
Information Center (DIC)
(Uplevel Cluster) 0127. When
remaining oil life is low, the
CHANGE ENGINE OIL SOON
message will appear on the
display. See Engine Oil
Messages 0134.
2. Press
Von 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.
See Engine Oil Life System 0230.

{Warning
If the key is unintentionally
rotated while the vehicle is
running, the ignition could be
moved out of the RUN position.
This could be caused by heavy
items hanging from the key ring,
or by large or long items attached
to the key ring that could be
contacted by the driver or
steering wheel. If the ignition
moves out of the RUN position,
the engine will shut off, braking
and steering power assist may be(Continued)

impacted, and airbags may not
deploy. To reduce the risk of
unintentional rotation of the
ignition key, do not change the
way the ignition key and Remote
Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
If the vehicle is equipped with a
keyed ignition, the ignition key, key
rings, and RKE transmitter,
if equipped, are designed to work
together. As a system, it reduces
the risk of unintentionally moving
the key out of the RUN position.
If replacements or additions are
required, see your dealer. Limit
added items to a few essential keys
or small, light items no larger than
an RKE transmitter.
Interference from radio-frequency
identification (RFID) tags may
prevent the key from starting the
vehicle. Keep RFID tags away from
the key when starting the vehicle.
The key that is part of the RKE
transmitter can be used for the
ignition and all locks if the vehicle is
a Key Access vehicle.
If the vehicle has the keyless
ignition, the key can be used for the
locks.

Programming Transmitters to
the Vehicle
Only RKE transmitters programmed
to the vehicle will work. If a
transmitter is lost or stolen, a
replacement can be purchased and
programmed through your dealer.
The vehicle can be reprogrammed
so that lost or stolen transmitters no
longer work. Any remaining
transmitters will need to be
reprogrammed. Each vehicle can
have up to eight transmitters
matched to it. Programming with a Recognized
Transmitter (Key Vehicles Only)
To program a new key:
1. Insert the original, already programmed key in the ignition
and turn the key to the ON/
RUN position.
2. Turn the key to LOCK/OFF, and remove the key.
3. Insert the new key to be programmed and turn it to the
ON/RUN position within
five seconds.
The security light will turn off
once the key has been
programmed.
4. Repeat Steps 1–3 if additional keys are to be programmed.
If a key is lost or damaged, see your
dealer to have a new key made.
Programming without a
Recognized Transmitter (Key
Vehicles Only)
Program a new key to the vehicle
when a recognized key is not
available. Canadian regulations
require that owners see their dealer. If there are no currently recognized
keys available, follow this procedure
to program the first key.
This procedure will take
approximately 30 minutes to
complete for the first key. The
vehicle must be off and all of the
keys you wish to program must be
with you.
1. Insert the new vehicle key into the ignition.
2. Turn to ON/RUN. The security light will come on.
3. Wait 10 minutes until the security light turns off.
4. Turn the ignition to LOCK/OFF.
5. Repeat Steps 2–4 two more times. After the third time, turn
to ON/RUN; the key is learned
and all previously known keys
will no longer work with the
vehicle.
Remaining keys can be learned by
following the procedure in
“Programming with a Recognized
Transmitter (Key Vehicles Only).”

Remote Vehicle Start
If equipped, this feature allows the
engine to be started from outside
the vehicle.
/(Remote Vehicle Start) : This
button will be on the RKE
transmitter if the vehicle has remote
start.
The climate control system will use
the previous settings during a
remote start. The rear defog may
come on during remote start based
on cold ambient conditions. The
rear fog indicator light does not
come on during remote start. If the
vehicle has heated seats, they may
come on during a remote start. See
Heated Front Seats 055.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
require a person using remote start
to have the vehicle in view. Check
local regulations for any
requirements.
