206 DRIVING AND OPERATING
Defensive Driving
Defensive driving means“always
expect the unexpected.” The first step
in driving defensively is to wear the
seat belt. See Seat Belts047.
.Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless and
make mistakes. Anticipate what
they may do and be ready.
.Allow enough following distance
between you and the driver in front
of you.
.Focus on the task of driving.
Impaired Driving
Death and injury associated with
impaired driving is a global tragedy.
{Warning
Drinking alcohol or taking drugs
and then driving is very dangerous.
Your reflexes, perceptions,
attentiveness, and judgment can be
affected by even a small amount of
alcohol or drugs. You can have a
(Continued)
Warning (Continued)
serious—or even fatal —collision
if you drive after drinking or taking
drugs.
Do not drive while under the
influence of alcohol or drugs,
or ride with a driver who has been
drinking or is impaired by drugs.
Find alternate transportation home;
or if you are with a group, designate
a driver who will remain sober.
Control of a Vehicle
Braking, steering, and accelerating are
important factors in helping to control
a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is about
three-quarters of a second. In that
time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in mind
include:
.Keep enough distance between you
and the vehicle in front of you.
.Avoid needless heavy braking.
.Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake normally
but do not pump the brakes. Doing so
could make the pedal harder to push
down. If the engine stops, there will
be some power brake assist but it will
be used when the brake is applied.
Once the power assist is used up, it
can take longer to stop and the brake
pedal will be harder to push.
Steering
Electric Power Steering
Caution
To avoid damage to the steering
system, do not drive over curbs,
parking barriers, or similar objects (Continued)

DRIVING AND OPERATING 219
Starting and Operating
New Vehicle Break-In
Caution
The vehicle does not need an
elaborate break-in. But it will
perform better in the long run if
you follow these guidelines:
.Do not drive at any one constant
speed, fast or slow, for the first
800 km (500 mi). Do not make
full-throttle starts. Avoid
downshifting to brake or slow the
vehicle.
.Avoid making hard stops for the
first 300 km (200 mi) or so.
During this time the new brake
linings are not yet broken in.
Hard stops with new linings can
mean premature wear and earlier
replacement. Follow this
breaking-in guideline every time
you get new brake linings.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start.
If the pushbutton start is not working,
the vehicle may be near a strong radio
antenna signal causing interference to
the Remote Keyless Entry (RKE)
system. See Remote Keyless Entry
(RKE) System Operation 07.
To shift out of P (Park), the vehicle
must be turned on and the brake
pedal must be applied. Stopping the Engine/OFF (No
Indicator Light) :
When the vehicle is
stopped, press ENGINE START/STOP
once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0224.
If the vehicle is in R (Reverse), D
(Drive) or M (Manual Mode), the
vehicle will shift to P (Park), the
ignition will turn off, and RAP will
remain active.
If the vehicle is in N (Neutral), the
ignition will return to ACC/
ACCESSORY and display the message
SHIFT TO PARK in the Driver
Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition will turn off.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering (Continued)

Warning (Continued)
systems and disable the airbags.
While driving, only shut the vehicle
off in an emergency.
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 and shift to P (Park).
4. Set the parking brake. See Electric
Parking Brake 0233. Press ENGINE
START/STOP to turn the
vehicle off. If the vehicle cannot be pulled over
and must be shut off while driving,
press and hold ENGINE START/STOP
for longer than two seconds, or press
twice in five seconds.
ACC/ACCESSORY (Amber Indicator
Light) :
This mode allows you to use
some electrical accessories when the
engine is off.
With the ignition off, pressing
ENGINE START/STOP once without
the brake pedal applied will place the
ignition system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after 10 minutes
to prevent battery rundown.
ON/RUN/START (Green Indicator
Light) : This mode is for driving and
starting. With the ignition off and the
brake pedal applied, pressing ENGINE
START/STOP once will place the
ignition system in ON/RUN/START.
Once engine cranking begins, release
the button. Engine cranking will
continue until the engine starts. The
ignition will then remain on. See
Starting the Engine 0220. Service Mode
This mode is available to verify the
proper operation of the malfunction
indicator lamp as may be required for
emissions inspection purposes and for
service and diagnostics. See
Automatic
Transmission 0226.
With the vehicle off, and the brake
pedal not applied, pressing and
holding ENGINE START/STOP for
more than five seconds will place the
vehicle in Service Mode. The
instruments and audio systems will
operate as they do in ON/RUN, but
the vehicle will not be able to be
driven. The engine will not start in
Service Mode. Press ENGINE START/
STOP again to turn the vehicle off.
Starting the Engine
Place the transmission in the proper
gear, P (Park) or N (Neutral). To restart
the engine when the vehicle is already
moving, use N (Neutral).

234 DRIVING AND OPERATING
EPB Release
To release the EPB:1. Turn the ignition on or to ACC/ ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red
parking brake status light is off.
If the amber service parking brake
warning light is on, release the EPB by
pressing and holding the EPB switch.
Continue to hold the switch until the
red parking brake status light is off.
If either light stays on after release is
attempted, see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
If you are towing a trailer and parking
on a hill, see Driving Characteristics
and Towing Tips 0271.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive
away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional
braking to activate the Antilock Brake
System (ABS) if the brake pedal is not
pushed hard enough to activate ABS
normally. Minor noise, brake pedal
pulsation, and/or pedal movement
during this time may occur. Continue
to apply the brake pedal as the driving
situation dictates. Brake Assist
disengages when the brake pedal is
released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature.
HSA does not replace the need to
pay attention and drive safely. You
may not hear or feel alerts or
warnings provided by this system.
Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See Defensive
Driving 0206.
When the vehicle is stopped on a
grade, Hill Start Assist (HSA) prevents
the vehicle from rolling in an
unintended direction during the
transition from brake pedal release to
accelerator pedal apply. The brakes
release when the accelerator pedal is
applied. If the accelerator pedal is not
applied within a few minutes, the
Electric Parking Brake will apply. The
brakes may also release under other
conditions. Do not rely on HSA to
hold the vehicle.
HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in
