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.
.Replace the vehicle's tires with the same
TPC Spec number molded into the tire's
sidewall near the size.
.Follow recommended scheduled
maintenance.
.Using Tour mode rather than Sport or
Track modes, will result in better Active
Fuel Management operation. SeeActive
Fuel Management 0197.
.For recommended shift speeds, see Dual
Clutch Transmission 0198.
Premium Fuel
Use the recommended fuel. See
Recommended Fuel 0226.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments have
enacted laws regarding driver distraction.
Become familiar with the local laws in
your area.
To avoid distracted driving, keep your eyes
on the road, keep your hands on the
steering wheel, and focus your attention on
driving.
.Do not use a phone in demanding driving
situations. Use a hands-free method to
place or receive necessary phone calls.
.Watch the road. Do not read, take notes,
or look up information on phones or
other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle features
before driving, such as programming
favorite radio stations and adjusting
climate control and seat settings. Program
all trip information into any navigation
device prior to driving.
.Wait until the vehicle is parked to
retrieve items that have fallen to the
floor.
.Stop or park the vehicle to tend to
children.
.Keep pets in an appropriate carrier or
restraint.
.Avoid stressful conversations while
driving, whether with a passenger or on a
cell phone.
{Warning
Taking your eyes off the road too long or
too often could cause a crash resulting in
injury or death. Focus your attention on
driving.

Driving and Operating 181
{Warning
Some of the adjustments and procedures
specified in this section may require
specialized skill, training, and equipment.
Failure to perform these procedures
properly could cause malfunction,
potentially resulting in death, personal
injury, or damage to the vehicle or
property. Do not attempt to perform
these adjustments or procedures unless
properly qualified.
Be sure to follow all service procedures
before driving the vehicle at track events or
competitively.
{Warning
Prior to each track event and again
before returning to public roads, tighten
the wheel nuts with a torque wrench to
the proper torque specification. Wheel
nuts that are improperly or incorrectly
tightened can cause the wheels to
become loose or come off, resulting in a
crash. See Capacities and Specifications
0 305 for wheel nut torque specifications. If equipped, the front license plate bracket
should be removed and replaced with the
aero cover for track use.
Engine Sound Management Setting
Caution
Do not place the vehicle in Engine Sound
Management–Stealth mode. Damage
could result to exhaust valve actuators.
Engine Oil
Caution
If the vehicle is used for track events and
competitive driving, the engine may use
more oil than it would with normal use.
Low oil levels can damage the engine.
Check the oil level often and maintain
the proper level. See Engine Oil0237.
Check the oil level often during track events
and competitive driving. See “Checking the
Engine Oil" in Engine Oil0237.
Engine Cooling
If reduced performance is experienced during
track events or competitive driving, turning
off the A/C will help to improve engine
performance. Maintain a mixture of 40% DEX-COOL
coolant and 60% clean, drinkable water to
optimize engine performance.
Fuel
Unleaded gasoline, rated at 93 octane or
higher, is required.
Caution
Some high octane fuels contain additives
and compounds that may damage the
vehicle and void the vehicle warranty. See
Prohibited Fuels
0226.
Dual Clutch Transmission Fluid
The transmission fluid and external filter
should be changed after every 24 hours of
track usage. If prompted by the transmission
fluid life monitor that remaining fluid life is
low, the fluid and external filter should be
changed as soon as possible.
Add an additional 2 L (2 qt) of DCT
transmission fluid prior to track usage. It is
not required to remove the additional 2 L
(2 qt) of DCT fluid.
Any transmission level set or change should
be performed at your dealer.

188 Driving and Operating
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. SeeTraction
Control/Electronic Stability Control 0206.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0204.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.Turn off cruise control.
.Turn on Weather Mode. See Driver Mode
Control 0208.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See Roadside Assistance Program
0 311. To get help and keep everyone in the
vehicle safe:
.Turn on the hazard warning flashers.
.Tie a red cloth to an outside mirror.
{Warning
Snow can trap engine exhaust under the
vehicle. This may cause exhaust gases to
get inside. Engine exhaust contains
carbon monoxide (CO), which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:
.Clear snow from the base of the
vehicle, especially any blocking the
exhaust pipe.
(Continued)
Warning (Continued)
.Open a window about 5 cm (2 in) on
the vehicle side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets on or under
the instrument panel.
.Adjust the climate control system to
circulate the air inside the vehicle and
set the fan speed to the highest
setting. See“Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0197.
To save fuel, run the engine for short
periods to warm the vehicle and then shut
the engine off and partially close the
window. Moving about to keep warm also
helps.
If it takes time for help to arrive, when
running the engine, push the accelerator
pedal slightly so the engine runs faster than
the idle speed. This keeps the battery
charged to restart the vehicle and to signal
for help with the headlamps. Do this as
little as possible, to save fuel.

{Warning
Things you put inside your vehicle
can strike and injure people in a
sudden stop or turn, or in a crash.
.Put things in the rear area of your
vehicle. Try to spread the weight
evenly.
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in your vehicle.
.When you carry something inside
the vehicle, secure it whenever
you can.
Starting and Operating
New Vehicle Break-In
Follow these recommended guidelines
during the first 2 414 km (1,500 mi) of driving
this vehicle. Parts have a break-in period and
performance will be better in the long run. During the first 800 km (500 mi), engine
torque will be limited in low gears.
For the first 322 km (200 mi):
.To break in new tires, drive at moderate
speeds and avoid hard cornering.
.New brake linings also need a break-in
period. Avoid making hard stops. This is
recommended every time brake linings
are replaced.
For the first 800 km (500 mi):
.Avoid full throttle starts and abrupt stops.
.Do not exceed 4000 rpm.
.Avoid driving at any one constant speed,
fast or slow, including the use of cruise
control.
.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. This rule applies at all times, not
just during the break-in period.
For the first 2 414 km (1,500 mi):
.Do not participate in track events, sport
driving schools, or similar activities.
.Check engine oil with every refueling and
add if necessary. Oil and fuel
consumption may be higher than normal.
Front Air Dam (and Splitter)
If equipped, the front air dam and splitter
have minimal ground clearance.
Under normal operation, the components
will occasionally contact some road surfaces
(speed bumps, driveway ramps, etc.). This
can be heard inside the vehicle as a scraping
noise. This is normal and does not indicate a
problem.
Use care when approaching bumps or
objects on road surfaces and avoid them
when possible.
If equipped, the Front Lift System may be
used to increase front air dam or splitter
clearance. See Front Lift System 0214.
Composite Materials
This vehicle may be equipped with parts
containing carbon fiber, sheet-molding
compound, or other composite materials.
Dealer-installed accessories may also contain
composite materials. These parts and
accessories may include the splitter or rocker
extensions.
