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.

Driver Mode Control
Driver Mode Control (DMC) adds a
sportier feel, provides a more
comfortable ride, or assists in different
weather conditions or terrains. This
system simultaneously changes the
software settings of various
sub-systems to optimize driving
performance. Depending on the option
package, available features, and mode
selection; the Exhaust, Suspension,
Transfer-Case, Steering, Brakes and
Powertrain will change settings to
achieve the desired mode
characteristics. If the vehicle is
equipped with Magnetic Ride Control,
selecting the various Driver Modes
adjusts the ride of the vehicle to
enhance the ride performance for the
road conditions and the
selected mode.
Driver Mode Control has multiple
modes: My Mode, Tour, Sport, Snow/
Ice, Track and V-Mode. The Track
Mode and V-Mode are for V-Series
models only. Tour, Sport, Snow/Ice,
and Track are four modes that have preset vehicle settings for use in
different driving conditions. For
further detail see
“Mode Description ”.
My Mode and V-Mode are two modes
which can be customized by the
driver. In these two modes, vehicle
settings are configured to enhance
and personalize the driving
experience. See “Drive Mode
Customization ”for further details on
available customizations.
Mode Activation

switch on the center console to make
a mode selection. Every press will
scroll to the next available mode.
When a mode is selected, a unique
and persistent indicator will be
displayed in the driver information
center (DIC).
V-Mode Button
To activate V-Mode, press the V-Mode
button on the steering wheel. To
deactivate, the driver can either select
a different mode through the DMC
switch or press the V-Mode button on
the steering wheel. When V-Mode is
deactivated through the V-Mode
button, DMC is always set back to
Tour Mode.
Mode Description
Tour Mode
Use for normal city and highway
driving to provide a smooth, soft ride.
This setting provides a balanced
setting between comfort and handling.
This is the standard mode. For further
details on Tour Mode see “Driver
Mode Selector Attributes Affected ”.
When Tour Mode is selected, no
indicator will display.
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When selected, the Sport Mode
indicator will display.
In this mode, the vehicle monitors
driving behaviors and automatically
enables Performance Shift Features
when spirited driving is detected.
These features maintain lower
transmission gears to increase
available engine braking and improve
acceleration response. The vehicle will
exit this feature and return to normal
operation after a short period when no spirited driving is detected. The
steering will change to provide more
precise control. If the vehicle has
Magnetic Ride Control, the suspension
will change to provide better
cornering performance. Competitive
Driving Mode (Only available on FE3
suspensions) can be accessed through
this mode. See
Competitive Driving
Mode 0191.
For further details on Sport Mode, see
“Driver Mode Selector Attributes
Affected”.
The Performance Algorithm Liftfoot
(PAL) feature is enabled in Sport
Mode. PAL allows the transmission to
hold the current gear after a quick
release of a heavily applied accelerator
pedal. This provides greater engine
braking and enhanced vehicle control.
When PAL is activated, there may be
an additional green gear symbol which
appears in the instrument cluster
display. See Performance Shifting Light
0 111.

Snow/Ice Mode
Snow/Ice Mode is used for slippery
surfaces to help control wheel speed.
This can compromise the acceleration
on dry asphalt.
Snow/Ice Mode will use a different
accelerator pedal map to optimize
traction on a slippery surface. The
accelerator pedal will reduce engine
torque at small pedal inputs.
When selected, the Snow/Ice Mode
indicator will display.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, seeIf the
Vehicle Is Stuck 0159.
For further details on Snow/Ice Mode
see “Driver Mode Selector Attributes
Affected”. Track Mode (V-Series Only)
Use when maximum vehicle handling
is desired. For use when driving on a
closed race course or drag strip.
When selected, the Track Mode
indicator will display.
When in Track Mode, the automatic
transmission and steering will
function similar to Sport Mode. The
accelerator pedal is adjusted to give
maximum control during the highest
level of spirited driving. The Magnetic
Ride Control will be set to the
optimum level for vehicle
responsiveness. Performance Traction
Management (PTM) can be accessed
through this mode. See
“Performance
Traction Management ”in Competitive
Driving Mode 0191.
For further details on Track Mode, see
“Driver Mode Selector Attributes
Affected”. My Mode
My Mode is used to personalize
everyday driving. This mode is
designed to allow the driver to
configure vehicle sub-systems to their
own preference for city or normal
