on fairly level ground, always set
the parking brake and move the
shift lever to P (Park). SeeShifting
Into Park 0224. If you are towing a
trailer, see Driving Characteristics
and Towing Tips 0290.
If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking brake
set. After shifting into P (Park), try to
move the shift lever out without first
pushing the button on the shift lever.
If you can, the shift lever was not
fully locked into P (Park).
Torque Lock
Torque lock is when the weight of the
vehicle puts too much force on the
parking pawl in the transmission. This
happens when parking on a hill and
shifting the transmission into P (Park)
is not done properly and then it is
difficult to shift out of P (Park). To
prevent torque lock, set the parking brake and then shift into P (Park). To
find out how, see "Shifting Into Park"
listed previously.
If torque lock does occur, the vehicle
may need to be pushed uphill by
another vehicle to relieve the parking
pawl pressure, so you can shift out of
P (Park).
Shifting out of Park
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to
prevent movement of the shift lever
out of P (Park), unless the ignition is
on and the brake pedal is applied.
The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See
Jump Starting - North
America 0374.
To shift out of P (Park): 1. Apply the brake pedal. 2. Release the parking brake. See
Electric Parking Brake 0235.
3. Press the shift lever button.
4. Move the shift lever.
If unable to shift out of P (Park): 1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift lever
button again.

Tap Shift
Caution
Driving with the engine at a high
rpm without upshifting while using
Tap Shift, could damage the vehicle.
Always upshift when necessary
while using Tap Shift.
If equipped, vehicles with Tap Shift
have controls on the back of the
steering wheel to manually shift the
automatic transmission.
To enter Permanent Tap Shift Mode: 1. Move the shift lever from D (Drive) to M (Manual Mode).
While in Tap Shift Mode, the M
on the PRNDM section of the
instrument cluster will become
highlighted, and the current gear
is indicated.
2. Tap the left control toward the driver to downshift, and the right
control toward the driver to
upshift. To shift to the lowest
available gear, press and hold the
left control.
3. To exit, move the shift lever back to D (Drive).
With the shift lever in D (Drive) and
not in Permanent Tap Shift Mode, the
Tap Shift controls will activate a
temporary tap manual shift mode,
allowing the transmission to be
manually shifted. The vehicle exits
Temporary Tap Shift Mode after the
accelerator pedal is steady for six seconds. Temporary Tap Shift
Mode holds a gear longer without
exiting when coasting, to provide
powertrain braking. The Temporary
Tap Shift Mode can also be
deactivated by holding the right
upshift control briefly.
While using Tap Shift, the vehicle will
have firmer, quicker shifting. You can
use this for sport driving or when
climbing or descending hills, to stay in
gear longer, or to downshift for more
power or engine braking.
The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine revolutions
per minute (rpm). The transmission
will not downshift if the engine rpm is
too high in the next lower gear,
or upshift to the next higher gear
when the maximum engine rpm is
reached.

238 DRIVING AND OPERATING
The braking system is computer
controlled and blends the regenerative
braking with the conventional
hydraulic disc brakes to meet any
requirements for deceleration. The
controller interprets the braking
request and uses regenerative braking,
conventional hydraulic braking, or a
combination of both as necessary.
Because the hydraulic braking system
uses an electronic booster for boost
assist on demand, under certain
conditions a motor noise may be
heard. This is normal operation.
SeeWarning Lights, Gauges, and
Indicators 0126 and Driver Information
Center (DIC) 0162. In the event of a
controller problem, the brake pedal
may be harder to push and the
stopping distance may be longer.
Regen on Demand
Regen on Demand allows the user to
select increased coast deceleration by
pressing the steering wheel tap
controls. It is activated temporarily
while in D (Drive) and permanently
while in M (Manual Mode). Increased
coast deceleration will be felt while the accelerator pedal is fully released
and lessened when the accelerator
pedal is pressed.
The brake pedal must be applied at
low speed, because Regen on Demand
will not stop the car.
The brake lamps may come on when
this feature is activated.
To enter Permanent Regen on
Demand Mode:
1. Move the shift lever from D (Drive) to M (Manual Mode).
While in Permanent Regen on
Demand, the M of the PRNDM
section of the instrument cluster
will become highlighted, and the
current coast deceleration level is
indicated. Level 1 (M1) provides
the most coast deceleration.
Level 4 (M4) provides the least
coast deceleration and is
equivalent to the level found in
D (Drive).
2. Tap the left control on the backof the steering wheel toward the
driver to select more coast
deceleration. Tap the right
control toward the driver to
select less coast deceleration. To
select the most coast
deceleration, press and hold the
left control.
3. To exit, move the shift lever back to D (Drive).
With the shift lever in D (Drive) and
not in Permanent Regen on Demand
Mode, the Tap Shift controls will
activate Temporary Regen on
Demand. The vehicle exits Temporary
Regen on Demand after the

252 DRIVING AND OPERATING
When following a vehicle and entering
a curve, ACC may not detect the
vehicle ahead and accelerate to the set
speed. When this happens, the vehicle
ahead indicator will not appear.
ACC may detect a vehicle that is not
in your lane and apply the brakes.
ACC may occasionally provide an alert
and/or braking that is considered
unnecessary. It could respond to
vehicles in different lanes, signs,
guardrails, and other stationary
objects when entering or exiting a
curve. This is normal operation. The
vehicle does not need service.Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. For
towing capability, see
Trailer Towing
(PLUG-IN Only) 0293 orTrailer Towing

Automatic Parking Assist (APA)
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still shift gears,
while the system applies the brakes
and accelerator. A display and audible
beeps help to guide parking
maneuvers.
Do not use APA when towing a trailer.
{Warning
APA may not detect objects in the
parking space, objects that are soft
or narrow, objects high off the
ground such as flatbed trucks,
objects below ground level such as
large potholes, or moving objects
(e.g. pedestrians). Always verify that
the parking space is appropriate for
parking a vehicle. APA does not
respond to changes in the parking
space, such as movement of an
adjacent vehicle, or a person or
object entering the parking space.
