Driving Information
Driving for Better Fuel
Economy
Driving habits can affect fuel mileage.
Here are some driving tips to get the
best fuel economy possible:
.Set the climate controls to the
desired temperature after the engine
is started, or turn them off when
not required.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid abrupt
stops.
.Avoid idling the engine for long
periods of time.
.When road and weather conditions
are appropriate, use cruise control.
.Always follow posted speed limits or
drive more slowly when conditions
require.
.Keep vehicle tires properly inflated.
.Combine several trips into a
single trip.

DRIVING AND OPERATING 211
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 or a brake
fault occurs, the brakes may lose
power assist. More effort will be
required to stop the vehicle and it can
take longer to stop.
Steering
Caution
To avoid damage to the steering
system, do not drive over curbs,
parking barriers, or similar objects
at speeds greater than 3 km/h
(1 mph). Use care when driving over
other objects such as lane dividers
and speed bumps. Damage caused
by misuse of the vehicle is not
covered by the vehicle warranty.
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance is
not required.
If power steering assist is lost due to a
system malfunction, the vehicle can
be steered, but may require increased
effort.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.

222 DRIVING AND OPERATING
{Warning
Track/course loads wear tires both
on the tread and internal to the
tire. When driven in track/course
conditions, even if tread is not worn
down to the treadwear indicator,
tires must be replaced after the
equivalent of two tanks of fuel or
approximately 160 km (100 mi).
Custom Launch Control
(If Equipped)
Custom Launch Control allows the
following parameters for Launch
Control to be modified:
.Launch RPM
.Slip Target (5%–15%)
.Surface Type
To adjust the Launch RPM, all of
these conditions must be met:
.The vehicle must be in Track Mode.
See “Track Mode ”under Driver Mode
Control 0258.
.Performance Traction Management
(PTM) Mode must be enabled. See
Driver Mode Control 0258.
.The steering wheel must be straight.
.The driver door must be closed.
.The transmission must be in D
(Drive) or forward gear.
.The parking brake must not be
engaged.
For more information on Competitive
Driving Mode, see Competitive Driving
Mode 0264.
1. Using the Driver Information
Center (DIC) buttons on the right
side of the steering wheel, navigate
to the Launch Control menu. See
Driver Information Center (DIC)
(Base Level) 0109 or
Driver Information Center (DIC)
(Uplevel) 0112.
2. Press SEL to select Custom.
3. Scroll down to Launch RPM.
4. Adjust the desired RPM: 1200–2400 for automatic

.The vehicle must be in D (Drive) for
an automatic transmission or
1 (First) gear for a manual
transmission.
.The parking brake must not be
engaged.
.The vehicle must be stopped on
level ground. The accelerator pedal
must not be applied.
1. Using the Driver InformationCenter (DIC) buttons on the right
side of the steering wheel, navigate
to the Line Lock menu within
Launch Control. See Driver
Information Center (DIC) (Base Level)
0 109 or
Driver Information Center (DIC)
(Uplevel) 0112.
2. Press the brake pedal firmly to
move the bar graph to 100%.
3. Release the brake pedal.
4. There are 15 seconds to complete the burnout and exit.
5. To release the brakes and roll out,
press
*and SEL at the same time.
If the burnout is not completed in
15 seconds, torque will be reduced to
idle, the parking brake will be applied,
Line Lock releases, and Custom
Launch Control will be disabled.
Ensure the parking brake is
disengaged to re-enter Launch
Control.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop
and accelerate. Always drive slower in
these types of driving conditions and
avoid driving through large puddles
and deep-standing or flowing water.

0 7.
To shift out of P (Park), the vehicle
must be on 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) 0237.
If the vehicle has an automatic
transmission, and is not in P (Park),
the ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition system will
turn OFF.
If the vehicle has a manual
transmission and is stationary, the
ignition will turn off, and Retained Accessory Power (RAP) will remain
active. See
Retained Accessory Power
(RAP) 0237.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is switched
to OFF and the driver door is opened.
A sound may be heard as the lock
actuates or releases. The steering
column lock may not release with the
wheels turned off center. If this
happens, the vehicle may 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.
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) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Electric
Parking Brake 0254.
{Warning
Turning 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 within five seconds.
