.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.
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.
Refer to the infotainment
section for more information
on using that system and the
navigation system, if equipped,
including pairing and using a
cell phone.
Defensive Driving
Defensive driving means
“always expect the
unexpected.” The first step in
driving defensively is to wear
the seat belt. See Seat Belts
0 55.

2. Using the G-Force Gaugein the HUD display, use
enough pedal force to
completely stop the vehicle
in four to five seconds.
(~0.7g Decel level to stop
the vehicle in a straight
line). If ABS activates,
braking is too hard.
3. Repeat the first two steps 20 consecutive times, this
should take about
five minutes.
4. After completing the 20 stops, cool the brakes by
driving for 8 km (5 mi) at
100 km/h (60 mph).
Alternative Closed Course
Brake Burnishing Procedure
This brake burnish procedure
should only be run on vehicles
with a factory equipped brake
system.
This procedure should only be
run on a track and only on dry
pavement. Brake pedal fade
will occur during this track
burnish procedure and can cause brake pedal travel and
force to increase. This could
extend stopping distance until
the brakes are fully burnished.
1. Start track lapping at lower speeds and lower
braking efforts for
three minutes of driving.
Allow for increased braking
distances due to reduced
brake output.
2. After Step 1, increase speed and braking effort
for the next six minutes of
lapping, gradually ending
up at 90% effort. Continue
to allow for increased
braking distance due to
reduced brake output.
3. Cool the brakes by lapping with minimal light braking
for six minutes.

Tire Inflation Pressure
Guidelines
Tire inflation pressures affect
vehicle handling and tire life,
and should be adjusted for
various types of tracks/
courses.
Inspect the tires prior to every
track/course session. Track/
course driving will reduce the
tire tread life.
To maximize tire life, drive
800 km (500 mi) prior to
racetrack driving or complete
the minimum track running
that will increase the tire
pressures by 35 kPa (5 psi).
After this, immediately let the
tires cool to cold pressures.

See Tire Pressure for
High-Speed Operation0429.
Tire Inflation Pressure for
Track Driving
For driving on a race course,
if the vehicle is equipped with
275/35ZR19 (100Y) and
305/30ZR19 (102Y) tires, set
the cold (stationary) tire
pressures to 28 psi. During
track sessions, set the tire
pressures at 35 to 38 psi for
hot tires. If pressures exceed
38 psi, adjust the pressures
down to 35 to 38 psi. Return
the tires to the recommended
cold tire inflation pressure
when track driving has ended.
Driving and Operating
{Warning
Operating the vehicle at high
speeds can be dangerous.
Improper tire inflation
pressure can put additional (Continued)
Warning (Continued)
strain on the tires and can
cause a sudden failure. Make
sure the tires are in
excellent condition, and use
the correct cold tire inflation
pressure for the vehicle load
and track/course.
{Warning
Tracks/courses put high
loads on tires operating at
high speed, which can lead
to tire failure if not inflated
properly. Always limit vehicle
cargo to the driver plus one
passenger with no additional
cargo.
{Warning
Track/course loads wear
tires both on the tread and
internal to the tire. When
driven in track/course(Continued)
Warning (Continued)
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
0 293.

258 Driving and Operating
{Warning
Wet brakes can cause
crashes. They might not
work as well in a quick stop
and could cause pulling to
one side. You could lose
control of the vehicle.
After driving through a large
puddle of water or a car/
vehicle wash, lightly apply
the brake pedal until the
brakes work normally.
Flowing or rushing water
creates strong forces.
Driving through flowing
water could cause the
vehicle to be carried away.
If this happens, you and
other vehicle occupants
could drown. Do not ignore
police warnings and be very
cautious about trying to
drive through flowing water.
Caution
Driving through deep
puddles or standing water
can cause water to come in
through the engine air intake
and damage the engine.
If deep puddles or standing
water cannot be avoided,
proceed with caution and do
not exceed 8 km/h (5 mph).
Do not drive through water
that may come close to or
cover the vehicle’s
underbody.
Hydroplaning
Hydroplaning is dangerous.
Water can build up under the
vehicle's tires so they actually
ride on the water. This can
happen if the road is wet
enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.There is no hard and fast rule
about hydroplaning. The best
advice is to slow down when
the road is wet.
Other Rainy Weather Tips
Besides slowing down, other
wet weather driving tips
include:
.Allow extra following
distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer
fluid reservoir filled.
.Have good tires with proper
tread depth. See Tires
0418.
.Turn off cruise control.
Hill and Mountain
Roads
Driving on steep hills or
through mountains is different
than driving on flat or rolling
terrain. Tips include:
.Keep the vehicle serviced
and in good shape.

much weight it may
properly carry: the Tire and
Loading Information label
and the Certification label.
{Warning
Do not load the vehicle
any heavier than the
Gross Vehicle Weight
Rating (GVWR), or either
the maximum front or
rear Gross Axle Weight
Rating (GAWR). This can
cause systems to break
and change the way the
vehicle handles. This
could cause loss of
control and a crash.
Overloading can also
reduce stopping
performance, damage the
tires, and shorten the life
of the vehicle. Tire and Loading
Information Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's
center pillar (B-pillar). The
Tire and Loading
Information label shows the
number of occupant
seating positions (1), and
the maximum vehicle
capacity weight (2) in
kilograms and pounds. The Tire and Loading
Information label also
shows the tire size of the
original equipment tires (3)
and the recommended cold
tire inflation pressures (4).
For more information on
tires and inflation see Tires
0
418 and
Tire Pressure 0427.
There is also important
loading information on the
Certification label. It may
show the Gross Vehicle
Weight Rating (GVWR) and
the Gross Axle Weight
Rating (GAWR) for the
front and rear axle. See
“Certification Label” later in
this section.

Ask your dealer for trailering
information or assistance.
Towing Equipment
Hitches
Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going
by, and rough roads can affect
the trailer and the hitch.
Never attach rental hitches or
other bumper-type hitches.
Only use frame-mounted
hitches that do not attach to
the bumper.
Always seal any holes in your
vehicle if the trailer hitch
removed. If not sealed, dirt,
water, and carbon monoxide
(CO) from the exhaust may
enter your vehicle. See Engine
Exhaust0276.
Consider using mechanical
sway controls with any trailer.
Ask a trailering professional
about sway controls or refer to the trailer manufacturer's
recommendations and
instructions.
Tires
.Do not tow a trailer while
using a compact spare tire
on the vehicle.
.Tires must be properly
inflated to support loads
while towing a trailer. See
Tires
0418 for instructions
on proper tire inflation.
Safety Chains
Always attach chains between
the vehicle and the trailer, and
attach the chains to the holes
on the trailer hitch platform.
Instructions about safety
chains may be provided by the
hitch manufacturer or by the
trailer manufacturer.
Cross the safety chains under
the tongue of the trailer to
help prevent the tongue from
contacting the road if it
becomes separated from the
hitch. Always leave just
enough slack so the combination can turn. Never
allow safety chains to drag on
the ground.
Trailer Brakes
Loaded trailers over 450 kg
(1,000 lb) must be equipped
with brake systems and with
brakes for each axle. Trailer
braking equipment conforming
to Canadian Standards
Association (CSA) requirement
CAN3-D313, or its equivalent,
is recommended.
State or local regulations may
require trailers to have their
own braking system if the
loaded weight of the trailer
exceeds certain minimums
that can vary from state to
state. Read and follow the
instructions for the trailer
brakes so they are installed,
adjusted, and maintained
properly. Never attempt to tap
into your vehicle's hydraulic
brake system. If you do, both
the vehicle anti-lock brakes
