Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may hear
a motor or clicking noise and feel the brake pedal
move a little during a stop, but this is normal.
Braking in Emergencies
With anti-lock brakes, you can steer and brake at the
same time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
Your vehicle has a traction control system called TCS
that limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the rear wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine power
(by closing the throttle and managing engine spark) to
limit wheel spin.
The TRACTION SYSTEM ACTIVE message will come
on when the TCS system is limiting wheel spin. See
DIC Warnings and Messages on page 3-54. You
may feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the TCS
system begins to limit wheel spin, the cruise control will
automatically disengage. When road conditions allow
you to safely use it again, you may re-engage the cruise
control. SeeTurn Signal/Multifunction Lever on
page 3-8.

Selective Ride Control
You may have a ride control system on your vehicle
called Magnetic Selective Ride Control. The system
provides the following performance benets:
Reduced Impact Harshness
Improved Road Isolation
Improved High-Speed Stability
Improved Handling Response
Better Control of Body Ride Motions
This knob is located on the
center console. Turn it to
select the suspension
of your choice.
TOUR:Use for normal city and highway driving. This
setting provides a smooth, soft ride.SPORT:Use where road conditions or personal
preference demand more control. This setting provides
more “feel”, or response to the road conditions.
You can select a setting at any time. Based on road
conditions, steering wheel angle and your vehicle speed,
the system automatically adjusts to provide the best
ride and handling. Select a new setting whenever driving
conditions change.
There are three Driver Information Center (DIC)
messages that are displayed when a malfunction occurs
with the Selective Ride Control system. Refer toDIC
Warnings and Messages on page 3-54.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Magnetic Speed Variable Assist
Steering
Your vehicle is equipped with a steering system that
continuously adjusts the effort you feel when steering at
all vehicle speeds. It provides ease when parking,
yet a rm, solid feel at highway speeds.

If the LOW OIL LEVEL message on the Driver
Information Center (DIC) comes on, it means you need
to check your engine oil level right away. For more
information, seeDriver Information Center (DIC)
on page 3-49.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil level every
time you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be on
level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or a cloth, then push it back in all the way. Remove
it again, keeping the tip down.
