DRIVING AND OPERATING 221
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If you add electrical parts or
accessories, you could change the
way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty. See
Add-On Electrical Equipment0280.
To start the vehicle: 1. With the Keyless Access system, the RKE transmitter must be in the
vehicle. Press ENGINE START/
STOP with the brake pedal applied.
When the engine begins cranking,
let go of the button. The idle speed
will go down as the engine warms
up. Do not race the engine
immediately after starting it. If the RKE transmitter is not in the
vehicle, if there is interference, or if
the RKE battery is low, a Driver
Information Center (DIC) message
will display. See
Remote Keyless
Entry (RKE) System Operation 07.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP immediately
after cranking has ended, can
overheat and damage the cranking
motor, and drain the battery. Wait
at least 15 seconds between each
try, to let the cranking motor
cool down.
2. If the engine does not start after five to 10 seconds, especially in
very cold weather (below −18 °C or
0 °F), it could be flooded with too
much gasoline. Try pushing the
accelerator pedal all the way to the
floor and hold it there, then press
ENGINE START/STOP for up to a
maximum of 15 seconds. Wait at
least 15 seconds between each try,
to allow the cranking motor to cool
down. When the engine starts, let go of the button and the
accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra
gasoline from the engine. Do not
race the engine immediately after
starting it. Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Stop/Start System
The Stop/Start system will shut off
the engine to help conserve fuel.
It has components designed for the
increased number of starts.
{Warning
The automatic engine Stop/Start
feature causes the engine to shut
off while the vehicle is still on. Do
not exit the vehicle before shifting
to P (Park). The vehicle may restart
and move unexpectedly. Always
shift to P (Park), and then turn the
ignition off before exiting the
vehicle.

232 DRIVING AND OPERATING
The transmission will not
automatically shift to the next higher
gear if the engine rpm is too high.
It will only automatically shift to the
next lower gear if the engine rpm is
much too low.
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate
in All-Wheel Drive (AWD) Mode.
When the AWD feature is active, the
system transfers engine power,
if required, to all four wheels. The
system is fully automatic and adjusts
to road conditions for improved
traction and control. In FWD Mode
engine power is transferred to the
front wheels only, and the AWD
feature is off.
The AWD feature is automatically
activated when certain modes are
selected using the Driver Mode
Control switch. When an AWD mode
change is requested the light will flash
briefly while the system is engaging
and the AWD light will be displayed
when the system is active. When anon-AWD Mode is selected, the light
will flash briefly while the system
disengages and a 2WD light will be
displayed when the AWD system is
off. See
Driver Mode Control 0236.
When a compact spare tire is installed
on an AWD vehicle, the system will
automatically detect the compact
spare and reduce AWD performance
to protect the system. To restore AWD
operation and prevent excessive wear
on the system, replace the compact
spare with a full-size tire as soon as
possible. See Compact Spare Tire 0341.
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
0 108.
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.

Do not use ACC when:
.On winding and hilly roads or
when the sensors are blocked by
snow, ice, or dirt. The system
may not detect a vehicle ahead.
Keep the entire front of the
vehicle clean.
.Visibility is low, such as in fog,
rain, or snow conditions. ACC
performance is limited under
these conditions.
.On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
J:Press to turn the system on or
off. The indicator turns white on the

The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 099. The
increment value used depends on the
units displayed.
Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD, if equipped. The gap
setting will be maintained until it is
changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See
Forward Collision Alert
(FCA) System 0258.
Alerting the Driver
With Head-Up Display
Without Head-Up Display If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, six red
lights or the collision alert symbol on
the HUD, if equipped, will flash on the
windshield. Either eight beeps will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. See
“Collision/Detection
Systems” underVehicle Personalization
0 120.
See Defensive Driving 0206.
Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD display,
if equipped.

Warning (Continued)
on an entrance or exit ramp. Always
be ready to use the brakes if
necessary.
{Warning
On curves, ACC may respond to a
vehicle in another lane, or may not
have time to react to a vehicle in
your lane. You could crash into a
vehicle ahead of you, or lose control
of your vehicle. Give extra attention
in curves and be ready to use the
brakes if necessary. Select an
appropriate speed while driving in
curves.
ACC may operate differently in a
sharp curve. It may reduce the vehicle
speed if the curve is too sharp.When following a vehicle and entering
a curve, ACC may not detect the
vehicle ahead and may 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.
