Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on th e windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid , remove ice once it has softened.
u When removing ice from around the wheel s, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressures, and check for damage and excessive wear.
2Checking and Maintaining Tires P. 609
•Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
■Exterior Checks1Exterior Checks
NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you've parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.

uuBefore Driving uDriving Preparation
Driving
• Store or secure all items on board properly.
u Carrying too much cargo, or improperly storing it, can affect your vehicle’s
handling, stability, sto pping distance, and tires, and make it unsafe.
2Maximum Load Limit P. 447
•Do not pile items higher than the seat height.
u They can block your view and may be thrown forward in the event of sudden
braking.
• Do not place anything in the front seat footwells. Make sure to secure the floor
mat.
u An object or unsecured floor mat can in terfere with your brake and accelerator
pedal operation while driving.
• If you have any animals on board, do not let them move around in the vehicle.
u They may interfere with driv ing and a crash could occur.
• Securely close and lock all doors and the hatch.
2 Locking/Unlocking the Doors from the Inside P. 156
•Adjust your seating position properly.

uuWhen Driving uShifting
Driving
Use the paddle shifters to change betw een 1st and 7th speeds without releasing
your hands from the steering wheel. The transmission switches to the 7-speed
manual shift mode when you pull a paddle shifter while driving. This mode is useful
when engine braking is needed.
■When the shift lever is in (D:
The shift mode goes into the 7-speed ma nual shift mode temporarily, and the
number is displayed in the shift indicator.
The 7-speed manual shift mode is canceled automatically if you drive at constant
speed or accelerate, and the number in the shift indicator goes off.
You can cancel this mode by pulling the
(+ paddle shifter for a few seconds.
The 7-speed manual shift mode is especially useful when reducing the vehicle speed
temporarily before making a turn.
■When the shift lever is in (S:
The shift mode goes into the 7-speed manual shift mode. The M indicator and the
speed number are displayed in the shift indicator. As the vehicle speed slows down,
the transmission automatically shifts down accordingly. When the vehicle comes to
a stop, it automatically shifts down into 1st.
If the vehicle speed increases and the engi ne speed reaches near the tachometer’s
red zone, the transmission automatically shifts up.
You can only pull away in 1st speed.
When canceling the 7-speed manual shift mode, move the shift lever from
(S to
(D. When the 7-speed manual sh ift mode is canceled, the M indicator and shift
indicator will turn off.
■7-Speed Manual Shift Mode1 7-Speed Manual Shift Mode
In the 7-speed manual shif t mode, the transmission
shifts up or down by operating either paddle shifter
under the following conditions:
Shift Up: The engine sp eed reaches the lowest
threshold of the hi gher speed position.
Shift Down: The engine sp eed reaches the highest
threshold of the lower speed position.
When the engine speed reaches near the
tachometer’s red zone, the transmission shifts up
automatically.
When the engine speed reaches the lowest threshold
of the selected speed positi on, the transmission shifts
down automatically.
Operating the paddle shifte rs on slippery surfaces
may cause the tires to lock up. In this case, the 7-
speed manual shift mode is canceled and goes back
to the normal D driving mode.

uuWhen Driving uLimited Slip Differential (LSD)
Driving
Limited Slip Differential (LSD)
LSD (limited slip differential) is a type of differential that delivers extra torque to the
wheel or the wheels with the most tracti on to minimize wheel slip and maintain
control of the vehicle.
■Limited Slip Differential (LSD)
2.0 L engine models
1 Limited Slip Differential (LSD)
NOTICE
Make sure both front tires of your vehicle are of the
same brand and specified si ze, and have equal wear.
Otherwise, the LSD may not function properly.

uuWhen Driving uLaneWatchTM*
Driving
LaneWatchTM*
LaneWatch is an assistance system that allows you to check the passenger side rear
areas displayed on the audio/in formation screen when the turn signal is activated to
the passenger’s side. A camera in the passenger side door mirror monitors these
areas and allows you to check for vehicles, in addition to your visual check and use
of the passenger door mirror. You can also keep the system on for your convenience
while driving.1 LaneWatchTM*
Important Safety Reminder
Like all assistance systems, LaneWatch has
limitations. Over reliance on LaneWatch may result in
a collision.
The LaneWatch func tion can be affected by weather,
lighting (including headli ghts and low sun angle),
ambient darkness, camera condition, and loading.
The LaneWatch may not prov ide the intended display
of traffic to the side and rear under the following
conditions:
•Your vehicle’s suspension has been altered,
changing the height of the vehicle.
•Your tires are over or under inflated.•Your tires or wheels are of varied size or
construction.
3WARNING
Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on LaneWatch while
driving.
Always look in your mi rrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.

uuWhen Driving uTire Pressure Monitoring System (TPMS)*
Driving
Tire Pressure Monitoring System (TPMS)*
Instead of directly measuring the pressu re in each tire, the TPMS on this vehicle
monitors and compares the rolling radius and rotational characteristics of each
wheel and tire while you are driving to determine if one or more tires are
significantly under-inflated.
This will cause the low tire pressure/TPMS
indicator to come on and a message to appear
on the driver information interface.1 Tire Pressure Monitoring System (TPMS)*
The system does not monitor the tires when driving
at low speed.
Conditions such as low ambient temperature and
altitude change directly a ffect tire pressure and can
trigger the low tire pressure/TPMS indicator to come on.
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS may not function pr operly if tire type and
size are mixed. Make sure to use the same size and
type of tire. 2 Checking and Maintaining Tires P. 609
The low tire pressure/TPMS indicator may come on
with a delay or may not come on at all when:
•You rapidly accelerate, decelerate, or turn the
steering wheel.
•You drive on snowy or slippery roads.•Tire chains are used.
The low tire pressure/TPMS indicator may come on
under the following conditions:
•A compact spare tire* is used.•There is a heavier and une ven load on the tires,
such as when towing a trailer, than the condition at
calibration.
•Tire chains are used.
