.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.
{Warning
Coasting downhill in N (Neutral) or
with the ignition off is dangerous.
This can cause overheating of the
brakes and loss of steering. Always
have the engine running and the
vehicle in gear. .
Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills; something
could be in your lane (e.g., stalled
car, accident).
. Pay attention to special road signs
(e.g., falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
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. See
Traction Control/Electronic Stability
Control 0198.
. 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) 0195.
. 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.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby. To get
help and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.

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.
For the first 2 414 km (1,500 mi):
. Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 engine rpm.
. Avoid driving at any one constant
speed, fast or slow.
. Avoid downshifting to brake or
slow the vehicle when the engine
speed will exceed 4000 rpm.
. Check engine oil with every
refueling and add if necessary. Oil
and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 mi).
. New brake linings also need a
break-in period. Avoid making
hard stops during the first 322 km (200 mi). This is
recommended every time brake
linings are replaced.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

196 DRIVING AND OPERATING
To set the parking brake, hold the
regular brake pedal down, then push
the parking brake pedal down.
If the ignition is on, the brake system
warning light will come on. SeeBrake
System Warning Light 0116.
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
To release the parking brake, hold the
regular brake pedal down, then push
down momentarily on the parking
brake pedal until you feel the pedal
release. Slowly pull your foot up off
the parking brake pedal. If the parking
brake is not released when you begin
to drive, the brake system warning
light will be on and a chime will
sound warning you that the parking
brake is still on.
Parking Brake (Electric)
If equipped with an Electric Parking
Brake (EPB), the switch is on the left
side of the instrument panel. The EPB
can always be activated, even if the
ignition is off. To prevent draining the
battery, avoid repeated cycles of the
EPB when the engine is not running.
The system has a red parking brake
status light and an amber parking
brake warning light. See Parking Brake
Light 0116 and Service Electric Parking
Brake Light 0117. There are also
parking brake-related Driver
Information Center (DIC) messages. See
Brake System Messages 0128. In
case of insufficient electrical power,
the EPB cannot be applied or released.
Before leaving the vehicle, check the
red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Lift up the EPB switch momentarily.
The red parking brake status light will
flash and then stay on once the EPB is
fully applied. If the red parking brake
status light flashes continuously, then
the EPB is only partially applied or
there is a problem with the EPB.
A DIC message will display. Release
the EPB and try to apply it again.
If the light does not come one,
or keeps flashing, have the vehicle
serviced. Do not drive the vehicle if
the red parking brake status light is
flashing. See your dealer. See Parking
Brake Light 0116.

198 DRIVING AND OPERATING
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade sufficient enough to activate
HSA. This feature is designed to
prevent the vehicle from rolling, either
forward or rearward, during vehicle
drive off. After the driver completely
stops and holds the vehicle in a
complete standstill on a grade, HSA
will be automatically activated. During
the transition period between when
the driver releases the brake pedal and
starts to accelerate to drive off on a
grade, HSA holds the braking pressure
for a maximum of two seconds to
ensure that there is no rolling. The
brakes will automatically release when
the accelerator pedal is applied within
the two-second window. It will not
activate if the vehicle is in a drive gear
and facing downhill, or if the vehicle
is facing uphill and in R (Reverse).
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any of
the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to the
spinning wheels and reduces engine
power to limit wheel spin.
StabiliTrak activates when the vehicle
senses a difference between the
intended path and the direction the
vehicle is actually traveling.
StabiliTrak selectively applies braking
pressure to any one of the vehicle
wheel brakes to assist the driver in
keeping the vehicle on the
intended path. If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road conditions
allow.
Both systems come on automatically
when the vehicle is started and begins
to move. The systems may be heard or
felt while they are operating or while
performing diagnostic checks. This is
normal and does not mean there is a
problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary to
turn TCS off if the vehicle gets stuck
in sand, mud, ice, or snow. See
If the
Vehicle Is Stuck 0180 and “Turning
the Systems Off and On ”later in this
section.

improperly installed. This would allow
fuel to evaporate into the atmosphere.
See
Malfunction Indicator Lamp (Check
Engine Light) 0114.
Caution
If a new fuel cap is needed, be sure
to get the right type of cap from
your dealer. The wrong type of fuel
cap may not fit properly, may cause
the malfunction indicator lamp to
light, and could damage the fuel
tank and emissions system. See
Malfunction Indicator Lamp (Check
Engine Light) 0114. Coupe
–Capless Fuel System
The coupe vehicle has a capless
refueling system and does not have a
fuel cap. The filling nozzle must be
fully inserted and latched prior to
starting fuel flow.
