REDUCED ACCELERATION DRIVE
WITH CARE
This message displays when the vehicle's
propulsion power is reduced. A reduction in
propulsion power can affect the vehicle's
ability to accelerate. If this message is on,
but there is no observed reduction in
performance, proceed to your destination.
Under certain conditions the performance

Electric Power Steering
The vehicle is equipped with an electric
power steering system, which reduces the
amount of effort needed to steer the
vehicle. It does not have power steering
fluid. Regular maintenance is not required.
If the vehicle experiences a system
malfunction and loses power steering,
greater steering effort may be required.
Power steering assist also may be reduced if
you turn the steering wheel as far as it can
turn and hold it there with force for an
extended period of time.
See your dealer if there is a problem.
Dynamic Rack Travel
Dynamic Rack Travel (DRT) is a steering
system feature of Magnetic Ride Control.
If equipped, this feature provides additional
maximum steering wheel rotation to allow
for tighter turns when driving a low speeds.
As the vehicle speed increases or if the
suspension encounters significant wheel
travel, such as a driveway, while at
maximum steering rotation, DRT may gently
push the steering back a small amount to
prevent the front tires from contacting the
vehicle. This is normal operation. There is no
customer interface or display for this
feature. DRT is not available when in
Track Mode.
Curve Tips
.Take curves at a reasonable speed.
.Reduce speed before entering a curve.
.Maintain a reasonable and steady speed
through the curve.
.Wait until the vehicle is out of the curve
before accelerating gently into the
straightaway.
Steering in Emergencies
.There are some situations when steering
around an obstacle may be more effective
than braking.
.Holding both sides of the steering wheel
allows you to turn 180 degrees without
removing a hand.
.The Antilock Brake System (ABS) allows
steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off the
edge of a road onto the shoulder while
driving. Follow these tips:

300 Vehicle Care
cleaning, it is expected that brake dust and
road grime will darken the high performance
thermal coating over time.
{Warning
Altering, removing, or painting over the
white thermal coating on carbon fiber
wheels can cause the wheels to overheat
and become damaged. Damaged wheels
could cause a crash. To prevent property
damage, personal injury, and/or death,
do not change the coating on the carbon
fiber wheels.
Caution
Carbon fiber wheels may be damaged if
the vehicle is not washed after driving on
roads that have been sprayed with
magnesium chloride or calcium chloride.
These are used on roads for conditions
such as dust and ice. Always wash the
carbon fiber with soap and water after
exposure.
Brake System
Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear
and rotors for surface condition. Inspect
drum brake linings/shoes for wear or cracks.
Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake,
master cylinder, brake fluid reservoir,
vacuum pipes, electric vacuum pump
including bracket and vent hose, if equipped.
If equipped with Z51, inspect brake cooling
components. SeeTrack Events and
Competitive Driving 0172.
Steering, Suspension, and Chassis
Components
Visually inspect steering, suspension, and
chassis components for damaged, loose,
or missing parts or signs of wear at least
once a year.
Inspect power steering for proper hook-up,
binding, leaks, cracks, chafing, etc.
Visually check constant velocity joint boots
and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood hinges,
and liftgate hinges, unless the components
are plastic. Applying silicone grease on
weatherstrips with a clean cloth will make
them last longer, seal better, and not stick
or squeak.
Underbody Maintenance
At least twice a year, spring and fall, use
plain water to flush any corrosive materials
from the underbody. Take care to
thoroughly clean any areas where mud and
other debris can collect.
Do not directly power wash the transfer
case and/or front/rear axle output seals.
High pressure water can overcome the seals
and contaminate the fluid. Contaminated
fluid will decrease the life of the transfer
case and/or axles and should be replaced.
Body Damage
If the vehicle is damaged and requires sheet
metal repair or replacement, make sure the
body repair shop applies anti-corrosion
material to parts repaired or replaced to
restore corrosion protection.
