202 Driving and Operating
Starting and
Operating New Vehicle Break-In Follow these recommended
guidelines during the first
2 400 km (1,500 mi) of driving this
vehicle. Parts have a break-in
period and performance will be
better in the long run.
For the first 2 400 km (1,500 mi):
.
Avoid full throttle starts and
abrupt stops.
.
Do not exceed 4000 engine rpm.
.
Avoid driving at any one
constant speed, fast or slow.
.
Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
.
Do not let the engine labor.
Never lug the engine in high
gear at low speeds. .
Do not participate in track
events, sport driving schools,
or similar activities during this
break-in period.
.
Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 400 km (1,500 mi).
.
To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
300 km (200 mi). New tires do
not have maximum traction and
may tend to slip.
.
New brake linings also need a
break – in period. Avoid making
hard stops during the first
300 km (200 mi). This is
recommended every time brake
linings are replaced. Ignition Positions
The vehicle has an electronic
keyless ignition with pushbutton
start.
Pressing the button cycles it through
three modes: ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/OFF.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference

Driving and Operating 203to the Keyless Access system. See
Remote Keyless Entry (RKE)
System Operation 0 29 .
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN, and the brake pedal must
be applied.
Stopping the Engine/OFF (No
Indicator Lights) : 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) 0 206 .
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a
message in the Driver Information
Center (DIC). See Transmission
Messages 0 156 . When the vehicle
is shifted into P (Park), the ignition
system will switch to OFF. Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
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, shift
to P (Park), and turn off the
ignition.
4. Set the parking brake. See
Electric Parking Brake 0 214 .{ WarningTurning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
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 the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after
five minutes to prevent battery
rundown.

release the button. Engine cranking
will continue until the engine starts.
See Starting the Engine 0 204 . The
ignition will then remain in ON/RUN.

service and 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 five seconds will place
the vehicle in Service Only 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 Only Mode. Press the
button again to turn the vehicle off. Starting the Engine Move the shift lever to P (Park) or

vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.

accessories, you could change
the way the engine operates. Any
resulting damage would not be
