DRIVING AND OPERATING 151
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.
Variable Effort Steering
The vehicle has a steering system that
varies the amount of effort required to
steer the vehicle in relation to the
speed of the vehicle.
The amount of steering effort required
is less at slower speeds to make the
vehicle more maneuverable and easier
to park. At faster speeds, the steering
effort increases to provide a sport-like
feel to the steering. This provides
maximum control and stability.
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 wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.

154 DRIVING AND OPERATING
Axle Fluid
Axles must have 2400 km (1500 mi)
before being used in track driving.
The front, if equipped with AWD, and
rear axle fluid temperatures may be
higher than when driving in severe
conditions. Drain and refill with new
fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. SeeRecommended
Fluids and Lubricants 0317.
Caution
During a first time track or racing
event, high axle temperatures can
occur. Damage could be caused to
the axle and would not be covered
by the vehicle warranty. Do not
drive as long or as fast the first
time the vehicle is driven on the
track or raced.
Engine Oil
Check the oil level often during track
events and competitive driving and
keep the oil level at or near the
upper mark.
Fuel
Use premium unleaded gasoline with
a posted octane rating of 93 at a track
event. Unleaded gasoline with a
posted octane rating of 91 may be
used, but performance will be
degraded. See Prohibited Fuels 0227.
Automatic Transmission Fluid
Have the transmission fluid set to the
track specific oil level prior to track
usage. Transmission fluid should be
changed after every 15 hours of track
usage. Any transmission level set or
change should be performed at your
dealer.
Brakes
Brake Fluid
For track events and competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a dry boiling point greater than 279 °C
(534 °F). After conversion to the high
performance brake fluid, follow the
brake fluid service recommendations
outlined by the fluid manufacturer. Do
not use silicone or DOT-5 brake fluids.
Caution
Removing the splash shield can
degrade wet braking performance,
as well as introduce brake pedal
pulsation, due to brake disc
exposure to road debris. Only
remove the front brake disc splash
shield and front tire deflector when
driving in track events.
Brake cooling can be improved if the
front brake disc splash shield and
front tire deflector are removed.
Removing the shield will require that
the suspension bushings and wheel
speed sensor wires visible to the brake
disc be protected with insulated
thermal wrapping.
Check the fluid level before each
competitive driving event.

DRIVING AND OPERATING 155
Brake Fade Warning Assist
The Brake Fade Warning Assist
system monitors the performance of
the brake system. If the system
detects brake fade, or if the brake
fluid is near the boiling point, the
driver will be alerted.
Stage 1 :The Driver Information
Center (DIC) displays a “Reduce
Braking to Avoid Overheating”
message and brake pedal effort and
travel is increased. When the message
displays, the driver should decrease
brake pedal pressure.
Stage 2 : The Driver Information
Center (DIC) displays a “Brakes
Overheated Service Now ”message that
the brake fluid temperature is
excessive and is about to boil. The
system increases brake pedal effort
and travel, and will also limit vehicle
speed. The driver should immediately
start a cool down lap if on the track.
If this message displays, take the
vehicle to be serviced at your dealer. Brake Burnishing (V-Series)
To prepare the V-Series brake system
for track events and racing, complete
the appropriate high performance
brake burnishing procedure described
below.
New brake pads must be burnished
before racing or other competitive
driving.
Caution
These procedures are specific to the
V-Series with performance brake
linings package. This procedure
should not be run on other models
as damage may result.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnishing
procedure or damage may occur to
the powertrain/engine. See
New
Vehicle Break-In 0163. When performed as instructed, this
procedure will not damage the brakes.
During the burnishing procedure, the
brake pads will smoke and produce an
odor. The braking force and pedal
travel may increase. After the
procedure is complete, the brake pads
may appear white at the rotor contact.
Run this procedure in a safe manner
and in compliance with all local and
state ordinances/laws regarding motor
vehicle operation. Run this procedure
only on dry pavement.
Racing/Track Brake Burnishing
Procedure
Caution
Brake 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. Apply the brakes 25 times starting at 100 km/h (60 mph) to
50 km/h (30 mph) while

DRIVING AND OPERATING 157
these types of driving conditions and
avoid driving through large puddles
and deep-standing or flowing water.
{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.
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 Tires0272.
. 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.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the vehicle
on a long downhill slope can cause
brake overheating, can reduce brake
performance, and could result in a
loss of braking. Shift the
transmission to a lower gear to let
the engine assist the brakes on a
steep downhill slope.

DRIVING AND OPERATING 193
Limited-Slip Differential
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With eLSD,
the vehicle has:
.Enhanced high-speed control.
. Improved traction through
corners, allowing more
acceleration.
. More precise steering.
. Increased vehicle agility.
. Integration with StabiliTrak/
Electronic Stability Control (ESC).
For vehicles with eLSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode 0191 and
Maintenance Schedule 0308.
Cruise Control
{Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.
With cruise control, a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot
on the accelerator. Cruise control does
not work at speeds below about
40 km/h (25 mph).
If the Traction Control/StabiliTrak/
Electronic Stability Control (ESC)
system begins to limit wheel spin
while using cruise control, the cruise control automatically disengages. See
Traction Control/Electronic Stability
Control
0183. If a collision alert
occurs when cruise control is
activated, cruise control is disengaged.
See Forward Collision Alert (FCA)
System 0214. When road conditions
allow cruise control to be safely used,
it can be turned back on.
Cruise control will disengage if either
TCS or StabiliTrak/ESC is turned off.
If the brakes are applied, cruise
control disengages.

signs, trees, or other objects. Always
signal turns well in advance. Do not
steer or brake suddenly.
Driving on Grades
Reduce speed and shift to a lower gear
before starting down a long or steep
downhill grade. If the transmission is
not shifted down, the brakes may
overheat and result in reduced braking
efficiency.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off immediately
after towing at high altitude on steep
uphill grades, the vehicle could show
signs similar to engine overheating. To
avoid this, let the engine run,
preferably on level ground, with the
transmission in P (Park) for a few
minutes before turning the engine off.
If the overheat warning comes on, see
Engine Overheating0256.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and trailer
on a level surface when possible.
When parking your vehicle and your
trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the brake
pedal to allow the chocks to
absorb the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal. .Start the engine.
. Shift into a gear.
. Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance when Trailer
Towing
The vehicle needs service more often
when used to tow trailers. See
Maintenance Schedule 0308. It is
especially important to check the
automatic transmission fluid, engine
oil, axle lubricant, belts, cooling
system, and brake system before and
during each trip.
Check periodically that all nuts and
bolts on the trailer hitch are tight.
