Driving and Operating 9-29
Manual Mode
Manual Paddle Shift
While in S (Sport Mode), the paddles
located on the steering wheel can
be used to manually up-shift or
down-shift the transmission.
The Manual Paddle Shift system is
activated from S (Sport Mode) by
pushing the paddle, above the
steering wheel spokes, to up-shift to
the next gear, or pulling on the
paddle, behind the steering wheel
spokes, to down-shift to the
next gear.When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift to 2 (Second)
or 3 (Third) gear. A higher gear
allows you to gain more traction on
slippery surfaces. If traction control
is active, upshifts are delayed to
increase your control of the vehicle.
See
Traction Control System (TCS)
on page 9‑36 Traction Control
System (TCS).
The Manual Paddle Shift system
can be deactivated by moving the
shift lever from S (Sport Mode) back
to D (Drive), or by holding either
up‐shift paddle for more than
one second.
The driver may choose to briefly
activate the Manual Paddle Shift
system while in D (Drive). Tapping
either the upshift or downshift
controls will place the transmission
in Manual Paddle Shift mode. The driver may then exit Manual
Paddle Shift mode by holding
either upshift control for more
than one second. The system will
return to automatic shifting after
10 seconds of cruising at a steady
speed and no manual shifts,
or when the vehicle comes
to a stop.
While the Manual Paddle Shift gear
selection system is active, the
transmission will automatically
downshift through the gears as the
vehicle slows. The transmission
will select 2 (Second) gear as the
vehicle stops. From a stop, the
vehicle will start from and hold
2 (Second) gear unless the driver
manually paddle shifts into a
different gear or selects D (Drive).

9-30 Driving and Operating
The driver can select 1 (First) gear
for maximum acceleration from
a stop.
When using the Manual Paddle
Shift feature while in S (Sport Mode),
the current gear will be displayed in
the Driver Information (DIC), or the
Head-Up Display (HUD), if the
vehicle has either of these features.
If the vehicle has a Head-Up
Display (HUD), seeHead-Up
Display (HUD) on page 5‑32. The Manual Paddle Shift system will
not allow either an up-shift or a
down-shift if the vehicle speed is too
fast or too slow, nor will it allow a
start from 4 (Fourth) or higher gear.
If up-shifting does not occur when
needed, vehicle speed will be
limited to protect the engine.
When the transmission gear does
not respond to a shift change,
the DIC will show an X over the
gear display.
When a requested shift is denied
due to the speed restrictions shown,
the DIC will momentarily show an
X over the gear display and a
chime will sound. If the vehicle has a HUD, and the
transmission gear does not respond
to a shift change, a chime will sound
and the HUD will momentarily show
an X over the gear display.
Manual Paddle Shift operation is
available for use with Cruise
Control. See
Cruise Control on
page 9‑45 Cruise Control for
more information.
The vehicle speeds required for
Manual Paddle Shift up-shifts
depend on several vehicle inputs,
which will vary the allowed up-shift
speed by a few km/h (mph).

9-32 Driving and Operating
Manual Transmission
This is the shift pattern for the
six-speed manual transmission.
Here is how to operate the
transmission:
1 (First):Press the clutch pedal
and shift into 1 (First). Then slowly
let up on the clutch pedal as you
press the accelerator pedal.
You can shift into 1 (First) when
you are going less than 64 km/h
(40 mph). If you come to a complete stop and it is hard to shift into
1 (First), put the shift lever in
Neutral and let up on the clutch.
Press the clutch pedal back down.
Then shift into 1 (First).
2 (Second):
Press the clutch
pedal as you let up on the
accelerator pedal and shift into
2 (Second). Then, slowly let up on
the clutch pedal as you press the
accelerator pedal.
3 (Third), 4 (Fourth), 5 (Fifth) and
6 (Sixth): Shift into 3 (Third),
4 (Fourth), 5 (Fifth) and 6 (Sixth) the
same way you do for 2 (Second).
Slowly let up on the clutch pedal as
you press the accelerator pedal.
To stop, let up on the accelerator
pedal and press the brake pedal.
Just before the vehicle stops, press
the clutch pedal and the brake
pedal, and shift to Neutral. Neutral:
Use this position when
you start or idle the engine. The
shift lever is in Neutral when it is
centered in the shift pattern, not in
any gear.
R (Reverse): To back up, press
down the clutch pedal and shift into
R (Reverse). Just apply pressure
to get the lever past 5 (Fifth) and
6 (Sixth) into R (Reverse). Let up
on the clutch pedal slowly while
pressing the accelerator pedal.
The six-speed manual transmission
has a feature that allows you to
safely shift into R (Reverse) while
the vehicle is rolling at less than
5 km/h (3 mph). You will be
locked out if you try to shift into
R (Reverse) while the vehicle is
moving faster than 5 km/h (3 mph).

Shift Speeds
(Manual Transmission)
{WARNING
If you skip a gear when you
downshift, you could lose control
of the vehicle. You could injure
yourself or others. Do not shift
down more than one gear at a
time when you downshift.This chart shows when to shift to the next higher gear for the best
fuel economy.
Manual Transmission RecommendedShift Speeds in km/h (mph)
Engine Acceleration Shift Speed
1 to 2 2 to 3 3 to 4 4 to 5 5 to 6
All Engines 24 (15) 40 (25) 64 (40) 72 (45) 80 (50)
If the engine speed drops below
900 rpm, or if the engine is not
running smoothly, you should
downshift to the next lower gear.
You may have to downshift two or
more gears to keep the engine
running smoothly or for good
engine performance. Notice:
When shifting gears, do
not move the shift lever around
unnecessarily. This may damage
the transmission. Shift directly
into the next gear.

One to Four Shift Light
(Manual Transmission)
When this light comes on, you can
only shift from 1 (First) to 4 (Fourth)
instead of 1 (First) to 2 (Second).
SeeOne-to-Four Shift Light (Manual
Transmission) on page 5‑23 for
more information.
Downshifting
(Manual Transmission)
Do not downshift into the gear
shown below at a speed greater
than shown in the table:
1 (First) 80 km/h (50 mph)
2 (Second) 119 km/h (74 mph)
3 (Third) 163 km/h
(101 mph)
4 (Fourth) 209 km/h
(130 mph)
Notice: If you skip more than one
gear when you downshift, or if
you race the engine when you
release the clutch pedal while
downshifting, you could damage
the engine, clutch, driveshaft or
the transmission. Do not skip
gears or race the engine when
downshifting. The six-speed transmission has a
spring that centers the shift lever
near 3 (Third) and 4 (Fourth). This
spring helps you know which gear
you are in when you are shifting.
Be careful when shifting from
1 (First) to 2 (Second) or
downshifting from 6 (Sixth) to
5 (Fifth). The spring will try to pull
the shift lever toward 4 (Fourth) and
3 (Third). Make sure you move the
lever into 2 (Second) or 5 (Fifth).
If you let the shift lever move in the
direction of the pulling, you may end
up shifting from 1 (First) to 4 (Fourth)
or from 6 (Sixth) to 3 (Third).
If the driver does not upshift as the
engine speed approaches fuel shut
off RPM, the engine speed will be
limited to protect the engine. See
Tachometer on page 5‑12
for more
information.

Driving and Operating 9-35
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5‑22. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

9-36 Driving and Operating
Parking Brake
The parking brake lever is located to
the right of the center console.
To set the parking brake, hold the
brake pedal down. Pull the parking
brake lever up. If the ignition is on,
the brake system warning light will
come on.
To release the parking brake, hold
the brake pedal down. Then push
the release button in as you move
the parking brake lever all the
way down.
Notice:Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
Brake Assist
This vehicle has a brake assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement
the power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle.
The stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time
is normal and the driver should
continue to apply the brake pedal
as the driving situation dictates.
The brake assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (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 displays on the Driver
Information Center (DIC) when TCS
is limiting wheel spin. See Ride
Control System Messages on
page 5‑45. The system may be
heard or felt while it is working, but
this is normal.
