not start. Move the steering wheel from left
to right while attempting to start the
vehicle. If this does not work, the vehicle
needs service.
If the vehicle must be shut off in an
emergency:1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location.
3. Come to a complete stop. Hold the brake pedal down and shift to P (Park). The
vehicle must be in P (Park) to turn the
ignition off.

must be shut off while driving, press and
hold ENGINE START/STOP for longer than
two seconds, or press twice in five seconds.

one time without the brake pedal applied
will place the ignition system in accessory.
The ignition will switch from accessory to
OFF after five minutes to prevent battery
rundown.
ON/RUN/START (Green Indicator Light) : This

ignition off, and the brake pedal applied,
pressing the button once will turn the
ignition on. Once engine cranking begins,
release the button. Engine cranking will
continue until the engine starts. See Starting
the Engine 0187.

diagnostics, and to verify the proper
operation of the malfunction indicator lamp
as may be required for emission inspection
purposes. With the vehicle off, and the
brake pedal not applied, pressing and holding the button for more than

Driving and Operating 197
To use this feature:1. Move the shift lever to L (Manual Mode).
2. Press the plus/minus button on the shift lever, to increase or decrease the gear
range available.
When shifting to L (Manual Mode), the
transmission will shift to a preset lower gear
range. For this preset range, the highest
gear available is displayed next to the L in
the DIC. See Driver Information Center (DIC)
(Base Level) 0106 or
Driver Information Center (DIC) (Uplevel)
0 108 for more information. All gears below
that number are available to use. For
example, when 4 (Fourth) is shown next to
the L, 1 (First) through 4 (Fourth) gears are shifted automatically. To shift to 5 (Fifth)
gear, press the + (Plus) button or shift into
D (Drive).
L (Manual Mode) will prevent shifting to a
lower gear range if the engine speed is too
high. If vehicle speed is not reduced within
the time allowed, the lower gear range shift
will not be completed. Slow the vehicle,
then press the
−(Minus) button to the
desired lower gear range.
While using the ERS, cruise control can
be used.
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate in
All-Wheel Drive (AWD) Mode.
The AWD system delivers power to all four
wheels and the system adjusts as needed to
improve traction.
Press the AWD switch on the center console
to activate the system. The AWD light will
flash briefly while the system is engaging
and stay lit to indicate AWD is active. Press
the switch again to disable the system. The
light will flash briefly while the system
disables and then stay off.
The AWD Mode will stay selected until the
mode is changed.
When operated in two-wheel drive, the
vehicle will deliver power to the front
wheels only and may provide better fuel
economy.
When using a compact spare tire on an
AWD vehicle, the system automatically
detects the compact spare and reduces AWD

performance to protect the system. To
restore full AWD operation and prevent
excessive wear on the system, replace the
compact spare with a full-size tire as soon as
possible. SeeCompact Spare Tire 0298.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake boost
have hydraulic brake circuits that are
electronically controlled when the brake
pedal is applied during normal operation.
The system performs routine tests and turns
off within a few minutes after the vehicle is
turned off. Noise may be heard during this
time. If the brake pedal is pressed during
the tests or when the electric brake boost
system is off, a noticeable change in pedal
force and travel may be felt. This is normal.
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
If there is a problem with ABS, this warning
light stays on. See Antilock Brake System
(ABS) Warning Light 0101.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing and feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.
Electric Parking Brake
The Electric Parking Brake (EPB) can always
be applied, even if the vehicle is off. In case
of insufficient electrical power, the EPB
cannot be applied or released. To prevent
draining the battery, avoid unnecessary
repeated cycles of the EPB.
The system has a red parking brake status
light and an amber service parking brake
warning light. See Electric Parking Brake
Light 0101 and
Service Electric Parking Brake Light 0101.
There are also parking brake-related Driver
Information Center (DIC) messages.
