With the shif t lever in ‘‘D’’ position,
you can select the Sequential
SportShift mode to shift gears much
like a manual transmission, but
without a clutch pedal. To enter the Sequential SportShif t
mode, move the shif t lever f urther to
the driver’s side. To return to ‘‘D,’’
move the shift lever to the
passenger’s side.
In Sequential SportShif t mode, each
time you push f orward on the shif t
lever, the transmission shifts to a
higher gear. Pull back on the lever to
downshif t. The number of the gear
selected is displayed on the
instrument panel.
When you move the shif t lever f rom
‘‘D’’ to ‘‘M’’ position, the display
shows the selected gear. While in the Sequential SportShif t
mode, you can also shif t up or down
using the (right side) or (lef t
side) paddle shif ters on the right and
lef t side of the steering wheel.
For up shif t, press the right side ( )
paddle shif ter.
For down shif t, press the lef t side
( ) paddle shif ter.

Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. Emergency
Brake Assist System gains the
stopping f orce when you depressed
thebrakepedalhardinanemergent
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear. Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness.
It also keeps your brake lights on all
the time, conf using drivers behind
you. Braking System Design

The anti-lock brake system (ABS)
helps prevent the brakes f rom
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much f aster than a
person can do it.
this def eats the purpose of the ABS.
Let the ABS work f or you by always
keeping f irm, steady pressure on the
brake pedal as you steer away from
the hazard. This is sometimes
ref erred to as ‘‘stomp and steer.’’
You will f eel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal: it is the ABS rapidly

ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.If this indicator comes on, the anti-
lock f unction of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.If the ABS indicator comes on while
driving, test the brakes as shown on
page . When the ABS indicator comes on,
you will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
inf ormation display.

on loose or
uneven surf aces, such as gravel or
snow, than a vehicle without anti-
lock.
Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road. such as trying to take a
corner too f ast or making a sudden
lane change. Always drive at a safe
speed f or the road and weather
conditions. It only helps with steering
control during braking. Important Saf ety Reminders A vehicle with A BS may require a longer distance to stop
A BS cannot prevent the loss of
stability. A BS will not prevent a skid that
results f rom changing direction
abruptly, A BS does not reduce the time or
distance it takes to stop the
vehicle.

The CMBS does not activate if the
speed dif f erence between your
vehicles is less than 10 mph (15
km/h). CMBS may also not
activate if you turn the steering
wheel to avoid the collision.The CMBS consists of a radar
sensor in the f ront grille, a brake
actuator in the engine compartment,
an indicator on the instrument panel,
seat belt e-pretensioners on the f ront
seats,andanon/off switchonthe
dashboard.
When the CMBS activates, the brake
lights also come on.
The collision mitigation brake
system (CMBS) can assist you when
there is a possibility of your vehicle
hitting the vehicle in f ront of you. It
is designed to reduce the speed of
your vehicle before an unavoidable
collision occurs and, if possible, to
alert you to a potential collision while
thereistimetopreventit.Hereisa
brief description of what the CMBS
can do:
When your speed is above 10 mph
(15 km/h), the CMBS radar
sensor in the f ront grille can sense
a vehicle ahead of you. When your
vehicle gets too close to the
vehicle ahead of you, the system
mayactivateawarningbeep,
causing automatic application of
the brakes, and causing the
e-pretensioners to tighten the
f ront seat belts (see page ). 23

the multi-information display will
show a ‘‘CHECK TIRE PRESSURE’’

Your vehicle has been designed to
primarily carry passengers and their
cargo. You can also use it to tow a
trailer if you caref ully observe the
load limits, use the proper equipment,
and f ollow the guidelines in this
section.The weight that
the tongue of a f ully-loaded trailer
puts on the hitch should be
approximately 10 percent of the
trailer weight. Too much tongue
load reduces front-tire traction and
steering control. Too little tongue
load can make the trailer unstable
and cause it to sway.
The
maximum allowable weight of the
trailer and everything in or on it
must not exceed 1,000 lbs (450 kg).
Towing a load that is too heavy
can seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain.

Exceeding any load limit or
improperly loading your vehicle
and trailer can cause a crash in
which you can be seriously hurt
or killed.
Check the loading of your
vehicle and trailer carefully
beforestartingtodrive.

Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
Follow all normal precautions when
parking, including f irmly setting the
parking brake and putting the
transmission in Park. Also, place
wheel chocks at each of the trailer’s
tires.
When driving down hills, reduce
your speed, and shif t down to second
gear. Do not ‘‘ride’’ the brakes, and
remember, it will take longer to slow
downandstopwhentowingatrailer. If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat. When climbing hills, closely watch
your temperature gauge. If it nears
the red (hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shif ts
