follow the trailer tongue weight recommendations. Refer
to “Trailer Towing” in this section for further informa-
tion.
When TSC is functioning, the “ESC Activation/
Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being
applied to individual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC system is in
the “Partial Off” or “Full Off” modes.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.It anticipates when an emergency braking situation may
occur by monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake system for a
panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When Rain Brake
Support is active, there is no notification to the driver and
no driver interaction is required.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the ESC and EPS
modules that provides torque at the steering wheel for
certain driving conditions in which the ESC module is
detecting vehicle instability. The torque that the steering
wheel receives is only meant to help the driver realize
514 STARTING AND OPERATING

WARNING!
Do not use Summer tires in snow/ice conditions. You
could lose vehicle control, resulting in severe injury
or death. Driving too fast for conditions also creates
the possibility of loss of vehicle control.
Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a
“mountain/snowflake” symbol on the tire sidewall.If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow
tires only in sets of four; failure to do
so may adversely affect the safety and
handling of your vehicle. Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h), refer
to original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states pro-
hibit studded tires; therefore, local laws should be
checked before using these tire types.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96 kPa). Once a
538 STARTING AND OPERATING

Run Flat tire reaches the run flat mode it has limited
driving capabilities and needs to be replaced immedi-
ately. A Run Flat tire is not repairable.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring section for more infor-
mation.
Spare Tires — If Equipped
NOTE:For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire Service Kit” in
“What To Do In Emergencies” for further information.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with a
compact or limited-use temporary spare installed.
Damage to the vehicle may result.
Spare Tire Matching Original Equipped Tire And
Wheel — If Equipped
Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the original
equipment tire and wheel found on the front or rear axle
of your vehicle. This spare tire may be used in the tire
rotation for your vehicle. If your vehicle has this option,
refer to an authorized tire dealer for the recommended
tire rotation pattern.

STARTING AND OPERATING 539

NOTE:The premium Tire Pressure Monitor System will
automatically locate the pressure values displayed in the
correct vehicle position following a tire rotation.
The suggested rotation method is the “rearward-cross”
shown in the following diagram.TIRE PRESSURE MONITOR SYSTEM (TPMS)
NOTE: For vehicles equipped with run flat tires — When
the TPMS indicates a tire pressure of 14 psi (96 kPa) or
lower, always check tire pressure and replace the tire at
the first opportunity. At inflation pressure of/or below 14
psi (96 kPa) the tire is in the run-flat mode of operation.
In this condition, it is recommended a vehicle maximum
speed of 50 mph (80 km/h) for a maximum distance of 50
miles (80 km). The manufacturer does not recommend
using the run flat feature while driving a vehicle loaded
at full capacity or towing a trailer.
The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold tire pressure.
The tire pressure will vary with temperature by about 1
psi (7 kPa) for every 12°F (6.5°C). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
Tire Rotation

STARTING AND OPERATING 547

•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump, therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines
that have these additives will help improve fuel
economy, reduce emissions, and maintain vehicle perfor-
mance.
Designated TOP TIER Detergent Gaso-
line contains a higher level of deter-
gents to further aide in minimizing
engine and fuel system deposits.
When available, the usage of Top Tier
Detergent gasoline is recommended.

Refer to local laws for maximum trailer towing speeds.
NOTE:
• The trailer tongue weight must be considered as part
of the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire
and Loading Information placard. Refer to “Tire–
Safety Information” in “Starting and Operating” for
further information.
• The manufacturer does not recommend using the run
flat feature while driving a vehicle loaded at full
capacity or towing a trailer.
Trailer Hitch Receiver Cover Removal
(SRT Models) — If Equipped
Your vehicle may be equipped with a trailer hitch re-
ceiver cover, this must be removed to access the trailer
hitch receiver (if equipped). This hitch receiver cover is
located at the bottom center of the rear fascia.
1. Turn the two locking retainers located at the bottom of the hitch receiver cover a 1/4 turn counterclockwise.
570 STARTING AND OPERATING

NOTE:Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for
more than two seconds, you must press the brake pedal
to engage DRIVE or REVERSE.
Use the least amount of accelerator pedal pressure that
will maintain the rocking motion without spinning the
wheels or racing the engine.
NOTE: Push the ESC Off switch (if necessary), to place
the Electronic Stability Control (ESC) system in Partial
Off mode, before rocking the vehicle. Refer to “Elec-
tronic Brake Control” in “Starting And Operating” for
further information. Once the vehicle has been freed,
push the ESC Off switch again to restore ESC On
mode.CAUTION!
• Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL
for at least one minute after every five rocking-
motion cycles. This will minimize overheating and
reduce the risk of transmission failure during pro-
longed efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shifting be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).

WHAT TO DO IN EMERGENCIES 601

Conditions that would require replacement:
•Rib chunking (one or more ribs has separated from belt
body)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs) •
Belt slips
• “Groove jumping (belt does not maintain correct
position on pulley)
• Belt broken (note: identify and correct problem before
new belt is installed)
• Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty component
such as a belt pulley. Belt pulleys should be carefully
inspected for damage and proper alignment.
Belt replacement on some models requires the use of
special tools, we recommend having your vehicle ser-
viced at an authorized dealer.
