Child Restraint
Everyone in your vehicle needs to be buckled up all the
time, including babies and children. Every state in the
United States and all Canadian provinces require that
small children ride in proper restraint systems. This is the
law, and you can be prosecuted for ignoring it.
Children 12 years and younger should ride properly
buckled up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
WARNING!
In a collision, an unrestrained child, even a tiny baby,
can become a projectile inside the vehicle. The force
required to hold even an infant on your lap could
become so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured. Any child riding in your
vehicle should be in a proper restraint for the child’s
size.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner’s Manual to ensure you have the correct seat
for your child. Use the restraint that is correct for your
child.

240 STARTING AND OPERATING

•You can start out in first or second gear. The system
will ignore attempts to upshift at too low of a vehicle
speed.
•The transmission will automatically downshift to first
gear when coming to a stop.
•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when Autostickis en-
gaged.
•The transmission will automatically shift up when
maximum engine speed is reached while Autostickis
engaged.
•Transmission shifting will be more crisp/abrupt when
Autostickis engaged.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the rear wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the rear
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have an accident. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).

STARTING AND OPERATING 269

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 known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when the roads are
slushy.
2. Slow down if the road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the vehicle in front of you to avoid a collision in a sudden
stop.
Your vehicle is equipped with a Limited Slip Differential
(LSD) that reduces, but does not eliminate, the amount of
wheel slip across a given axle for improved handling.
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.
270 STARTING AND OPERATING

required. However, the conventional brake system will
continue to operate normally if the “Brake Warning
Light” is not on.
If the “ABS Warning Light” is on, the brake system should
be serviced as soon as possible to restore the benefits of
anti-lock brakes. If the “ABS Warning Light” does not come
on when the ignition switch is turned to the ON position,
have the bulb repaired as soon as possible.
If both the “Brake Warning Light” and the “ABS Warning
Light” remain on, the ABS and EBD systems are not
functioning. Immediate repair to the ABS system is
required.
MULTI-DISPLACEMENT SYSTEM (MDS) (IF
EQUIPPED) – 5.7L ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESP. This
system includes the ABS (Anti-Lock Brake System), the
TCS (Traction Control System), the BAS (Brake Assist
System), and the ESP (Electronic Stability Program).
These systems work together to enhance both vehicle
stability and control in various driving conditions.
An additional electronic brake control feature called Hill
Start Assist (HSA) is standard on manual transmission
models.
ABS (Anti-Lock Brake System) — If Equipped
This system aids the driver in maintaining vehicle control
under adverse braking conditions by controlling hydrau-
lic brake pressure. This prevents wheel lock-up to help
280 STARTING AND OPERATING

avoid skidding on slippery surfaces during braking. For
more information about ABS, refer to “Anti-Lock Brake
System” in Section 5.
WARNING!
The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
ABS cannot prevent accidents, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.
TCS (Traction Control System) — If Equipped
This system monitors the amount of wheel spin of each
driven wheel. If wheel spin is detected, brake pressure is
applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability.
A feature of the TCS system functions similar to a
limited-slip differential (LSD) and controls the wheel
spin across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in the
“Partial Off” mode. Refer to “ESP (Electronic Stability
Program)” in this section for more information.
BAS (Brake Assist System) — If Equipped
This system complements the ABS by optimizing the
vehicle braking capability during emergency braking
maneuvers. This system detects an emergency braking

STARTING AND OPERATING 281

NOTE:
•The “ESP/TCS Indicator Light” and the “ESP/BAS
Malfunction Indicator Light” will turn on momen-
tarily each time the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESP System
will be ON even if it was turned OFF previously.
•The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when the ESP becomes inactive following the
maneuver that caused the ESP activation.
TIRE SAFETY INFORMATION
Tire Markings

dards Code (TIN)4 — Maximum Load
2 — Size Designation 5 — Maximum Pressure
3 — Service Description 6 — Treadwear, Traction and
Temperature Grades 288 STARTING AND OPERATING

WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
an accident resulting in serious injury or death.
Use only the tire and wheel sizes with load ratings
approved for your vehicle.
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.
(Continued)
WARNING! (Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size may
result in false speedometer and odometer readings.
TIRE CHAINS
Use only compact chains or other traction aids that meet
SAE type “Class S” specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer. In addition, only install tire chains on
P215/65 R17, P225/60 R18, and P235/55 R18 size tires.
The 245/45 R20 size tires do not provide adequate
clearance for tire chains.
304 STARTING AND OPERATING

WARNING!
•You should not try to start your vehicle by pushing
or towing.
•Do not connect the cable to the negative post of the
discharged battery. The resulting electrical spark
could cause the battery to explode.
•During cold weather when temperatures are be-
low the freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode. The
battery temperature must be brought above the
freezing point before attempting jump-start.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around thefront wheels. Then shift back and forth between RE-
VERSE and DRIVE. Using minimal accelerator pedal
pressure to maintain the rocking motion, without spin-
ning the wheels, is most effective.
NOTE:Turn off the Electronic Stability Program (ESP)
before rocking the vehicle. Refer to “Electronic Stability
Program,” or “Traction Control” in Section 5.
CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween “1st” and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drivetrain damage
may result.
•Racing 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 35 mph (55 km/h).

WHAT TO DO IN EMERGENCIES 359

Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These grades represent the tire’s ability to stop on
wet pavement, as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor-
mance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
Temperature Grades
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat
and its ability to dissipate heat, when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance, which all
passenger car tires must meet under the Federal Motor
