CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite

and damage the converter and vehicle. If the ve-
hicle has a discharged battery, booster cables may
be used to obtain a start from a booster battery or
the battery in another vehicle. This type of start can
be dangerous if done improperly, so follow this
procedure carefully. Refer to “Jump-Starting” in
“What To Do In Emergencies” for further informa-
tion.
If the engine is flooded, it may start to run, but not have
enough power to continue running when the ENGINE
START button is released. If this occurs, continue crank-
ing up to 15 seconds with the accelerator pedal pushed
all the way to the floor. Release the accelerator pedal and
the ENGINE START button once the engine is running
smoothly. If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the “Normal Starting” procedure should
be repeated.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
MANUAL TRANSMISSION
NOTE:
The parking brake should be engaged and the
shift lever placed into REVERSE before leaving the
vehicle, especially when parked on an incline.
Your vehicle is equipped with a high torque capacity dual
disc clutch. The clutch pedal must be fully pressed to the
floor during each shift. As you release the clutch pedal,
lightly press the accelerator pedal.

(clutch pedal released), but it may also be heard when
driving. The noise may also be more noticeable when
the transmission is warm. This noise is normal and is
not an indication of a problem with your clutch or
transmission.
• You must always use first gear (or REVERSE) when
starting from a standing position.
CAUTION!
Always make sure the vehicle comes to a complete
stop before shifting into REVERSE. Failure to do so
may result in transmission damage.
Recommended Shift Speeds
To use your manual transmission for fuel economy it
should be upshifted as listed below. Shift at the vehicle
speeds listed for acceleration. Earlier upshifts during cruise conditions (relatively steady speeds) will result in
increased fuel economy, and may be used as indicated.
MANUAL TRANSMISSION
RECOMMENDED SHIFT SPEEDS 1-4 4-5 5-6
mph 17 4550
(km/h) (27) (72) (80)
Higher upshift speeds may be used to obtain a desired
acceleration rate.
Skip Shift Indicator Light
There are times when you must shift the trans-
mission directly from first gear into fourth gear
instead of from first gear into second gear. This
is to help you get the best possible fuel
economy from your vehicle. This occurs when engine
250 STARTING AND OPERATING

coolant is higher than 107°F (42°C), and vehicle speed is
greater than 16 mph (26 km/h) but less than 18 mph
(29 km/h), and engine speed is less than 1,550 RPM, and
the transmission is in first gear, and the accelerator is at
20% throttle or less. The “Skip Shift Indicator Light”
located in the tachometer will illuminate during these
times.
When the “Skip Shift Indicator Light” illuminates, the
shift mechanism will only allow shifts from first gear to
fourth gear. After you shift the transmission into fourth
gear, you can press the clutch in and shift to another
forward gear.
Downshifting - Proper downshifting will improve fuel
economy and prolong engine life.
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.CAUTION!
If you skip more than one gear while downshifting
or downshift at too high a vehicle speed, you could
damage the engine, transmission, or clutch.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have a collision.
STREET/RACE MODE — IF EQUIPPED

STARTING AND OPERATING 253

NOTE:If the cluster launch DID message indicates all
conditions are correct for launch and the throttle is
pressed to the floor quickly (within approximately 1/2
second) the system will hold the engine speed to a preset
speed (below the engine rev limiter speed).
6. Release the clutch aggressively. Do not ride the clutch.
Release the accelerator pedal to deactivate launch con-
trol. Pushing the launch control button or actuating the
brakes will also deactivate launch control.
NOTE:
• Launch Mode brings the engine to optimum launch
RPM and waits for the driver to release the clutch.
Launch Mode then uses engine throttle only to achieve
controlled wheelslip for maximum acceleration
through first gear.
• Launch Mode can be used in any of the Electronic
Stability Control (ESC) Modes. •
Launch Mode should not be used within the first 500
miles (805 km) of engine break-in.
WARNING!
Launch Mode is intended for off-highway or off-road
use only and should not be used on any public
roadways. It is recommended that this feature be
used in a controlled environment, and within the
limits of the law. The capabilities of the vehicle as
measured by the performance pages must never be
exploited in a reckless or dangerous manner, which
can jeopardize the user ’s safety or the safety of
others. Only a safe, attentive, and skillful driver can
prevent accidents.
254 STARTING AND OPERATING

NOTE:
•All SRT vehicles are track tested for 24 hours of
endurance, however, it is recommended that suspen-
sion system, brake system, prop shaft, and ½ shaft
boots should be checked for wear or damage after
every track event.
• Track usage results in increased operating tempera-
tures of the engine, transmission, clutch, driveline and
brake system. This may affect noise (NVH) counter-
measures designed into your vehicle. New compo-
nents may need to be installed to return the system to
the original NVH performance.
For ACR models, please review the supplemental manual
for track tips.DRIVING ON SLIPPERY SURFACES
Acceleration
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
You could lose control of the vehicle and possibly
have a collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
256 STARTING AND OPERATING

1. Slow down during rainstorms or when roads areslushy.
2. Slow down if road has standing water or puddles.
CAUTION!
Driving your vehicle through deep puddles at speeds
over 5 mph (8 km/h), may cause water to be ingested
into the engine. This can cause severe engine dam-
age.
3. Replace tires when tread wear indicators first become visible.
4. Keep tires properly inflated.
5. Maintain enough distance between your vehicle and the vehicle in front of you to avoid a collision in a
sudden stop.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.

STARTING AND OPERATING 257

Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Cautions
and Warnings before doing so.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
• Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stopping
distances. Therefore, after driving through stand-
ing water, drive slowly and lightly press on the
brake pedal several times to dry the brakes.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your pas-
sengers, and others around you.
CAUTION!
• Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
• Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, trans-
mission, axle, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue to
(Continued)
258 STARTING AND OPERATING

CAUTION!(Continued)
operate the vehicle if any fluid appears contami-
nated, as this may result in further damage. Such
damage is not covered by the New Vehicle Limited
Warranty.
• Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost. If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•
Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
