uuTowing a Trailer uTowing Preparation
262
Driving
Towing equipment varies by the size of your trailer, how much load you are towing,
and where you are towing.
■Hitches
The hitch must be of an approved type and properly bolted to the underbody.
■Safety chains
Always use safety chains when you tow a trailer. Leave enough slack to allow the
trailer to turn corners easily, but do not allow the chains to drag on the ground.
■Trailer brakes
Recommended for any trailer with a total weight of 1,000 lbs (450 kg) or more:
There are two common types of trailer brake s: surge and electric. Surge brakes are
common for boat trailers, since the brakes will get wet. If you choose electric brakes,
be sure they are electronically actuated. Do not attempt to attach trailer brakes to
your vehicle’s hydraulic system, as it w ill lower braking effectiveness and create a
potential hazard.
■Additional towing equipment
Many states and provinces/territories requi re special outside mirrors when towing a
trailer. Even if mirrors are not required in your locale, you should install special
mirrors if visibility is restricted in any way.
■Towing Equipment and Accessories1Towing Equipment and Accessories
Make sure that all equipment is properly installed and
maintained, and that it meets federal, state, province/
territory, and lo cal regulations.
Consult your traile r sales or rental agency if any other
items are recommended or required for your towing
situation.
The lighting and wiring of tra ilers can vary by type
and brand. If a connector is required, it should only
be installed by a qua lified technician.

Driving Safely with a Trailer
• Have the trailer properly serviced and keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2Towing Load Limits P. 261
•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the tr ailer so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressures of the traile r tires, including the spare.
• Drive slower than normal.
• Obey posted speed limits for vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
• Turn more slowly and with a wider turning arc than normal.
• Allow more time and distance for braking.
• Do not brake or turn suddenly.
• Monitor your temperature gauge. If it nears the red (Hot) mark, turn off the
climate control system and reduce speed. Pull to the side of the road safely to cool
down the engine if necessary.
• Shift to the
(S position if the transmission shifts frequently.

uuWhen Driving uAdaptive Cruise Control (ACC)*
Driving
Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed and a set following distance behind a
vehicle detected ahead of yours, without you having to keep your foot on the brake
or the accelerator.1 Adaptive Cruise Control (ACC)*
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe distance between your vehicle and other vehicles.
The radar sensor for ACC is shared with the collision
mitigation braking system
TM (CMBSTM).

(CMBSTM)* P. 318
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera

3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when travelling on open
highways in good weather.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below
22 mph (35 km/h), ACC will
automatically cancel and no longer will
apply your vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.

uuWhen Driving uVehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
Continued
Driving
Vehicle Stability Assist (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine ou tput and selectively applying the brakes.
When VSA ® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® indicator comes on and stays on
while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and alwa ys leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parking.
To apply:
Depress the parking brake pedal down with
your foot.
To release:
1. Depress the brake pedal.
2. Depress the parking brake.
■Parking Brake1Parking Brake
NOTICE
Release the parking brake fu lly before driving. The
rear brakes and axle can be damaged if you drive
with the parki ng brake applied.
If you start driving without fully releasing the parking
brake, a buzzer sounds as a warning, and RELEASE
PARKING BRAKE /Release Parking Brake appears
on the multi-information display.
Always apply the parking brake when parking.

315
uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps reduce the effort needed on the brake pedal. The brake assist system increases
the stopping force when you depress the brake pedal hard in an emergency
situation. The anti-lock brake system (ABS) helps you retain steering control when
braking very hard.
2 Brake Assist System P. 317
2 Anti-lock Brake System (ABS) P. 316
■Foot Brake1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, the brake pads need to be
replaced. Have the vehicle checked by a dealer.
Constantly using the brak e pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal and downshifting to a
lower gear.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.
Your vehicle is equipped with a hydraulic brake
booster that, under certain conditions, such as
braking at high altitudes, supplements the vacuum
power assist. When the hydraulic brake booster
activates, you may hear a motor sound and a slight
vibration in the pedal. This is normal.

316
uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you w ill need to press on the brake pedal very
hard before the ABS activates. However, you may feel the ABS activate immediately
if you are trying to stop on snow or ice.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have the vehicle
checked by a dealer immediately.
The ABS does not reduce the ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
•When tire chains are installed.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.
