Trailer Stability Assist
*
Helps to stabilize the vehicle and trailer when the trailer severely sways.■How trailer stability assist works
When the vehicle and trailer become unstable while driving, trailer stability assist
determines the cause. If the trailer oscillation is detected as the cause, and the
swaying increases, the system applies the brakes or controls engine output to reduce
vehicle speed.
Both the vehicle and trailer brake lights come on automatically if you brake to
reduce vehicle speed.
1 Trailer Stability Assist
*
Trailer stability assist is not a function that prevents
the vehicle and trai ler from swaying. Avoid high
speeds, abrupt steering, improper trailer load, and
sudden braking to keep the trailer from swaying.
When swayed too severely, the system becomes
ineffective, and you may loose control of your
vehicle, causing the trailer to roll over or get
damaged. 2 Driving Safely with a Trailer P. 320
Trailer towing sway is caused by:•Crosswinds•Improper towbar down load•Excessive Speed
The VSA ® system indicator blinks during the trailer
stability assist operation.

• 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.
If the vehicle tires slip when retrieving a boat from the water, keep the transmission
in
(D
and do not use the sequential shift mode in
(S
. This prevents damage to the
transmission.
Towing Your VehicleYour vehicle is not designed to be towed behind a motor home. If your vehicle needs
to be towed in an emergency, refer to the emergency towing information.2 Emergency Towing P. 480■

3. Press the ENGINE START/STOP button
without depressing the accelerator pedal.
The engine will crank until it starts.
1 Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate control
system, and rear defogger in order to reduce battery drain.If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
Bring the keyless access remote close to the ENGINE
START/STOP button if the battery in the keyless
access remote is weak. 2 If the Keyless Access Remote Battery is
Weak P. 463
The engine may not start if the keyless access remote
is subjected to strong radio waves.
Do not hold the ENGINE START/STOP button to
start the engine.
If the engine does not start, wait at least 10 seconds
before trying again.

uuWhen Driving uPrecautions While Driving
Driving
Precautions While DrivingUtility vehicles have a significantly higher rollover rate than other types of vehicles.
To prevent rollovers or loss of control:
• Take corners at slower speeds than you would with a passenger vehicle.
• Avoid sharp turns and abrupt maneuvers whenever possible.
• Do not modify your vehicle in any way that you would raise the center of gravity.
• Do not carry heavy cargo on the roof.
Never carry more than 165 lbs (75 kg) of cargo on the roof rack (Acura accessory).
Avoid driving in deep water and on flooded roads. This can damage the engine,
driveline, or cause electrical component failure.
If there is a strong impact with something under th e vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.■

Other Precautions
1 Precautions While DrivingNOTICEDo not operate the shift lever while pressing the
accelerator pedal. You could damage the
transmission.NOTICEIf you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel on
the full left or right position for a while, the system
heats up. The system goes into a protective mode,
and limits its performance. The steering wheel
becomes harder and harder to operate. Once the
system cools down, the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the power mode is set to ACCESSORY or VEHICLE
OFF (LOCK) while driving, the engine will shut down
and all steering and brake power assist functions will
stop, making it difficult to control the vehicle.
Do not put the shift lever in
(N, as you will lose
engine braking (and acceleration) performance.
During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as not to damage the engine or powertrain.
Avoid hard braking for the first 200 miles (300 km).
You should also follow this when the brake pads are
replaced.

uuWhen Driving uAutomatic Transmission
Driving
Automatic TransmissionThe engine runs at a higher idle speed and creeping increases.
Keep the brake pedal firmly depressed when stopped.
Quickly depressing the accelerator pedal while driving uphill may cause the
transmission to drop to a lower gear, unexpectedly increasing vehicle speed. Depress
the accelerator pedal carefully, especially on slippery roads and curves.■
