uuTowing a Trailer uDriving Safely with a Trailer
Driving
Driving Safely with a Trailer• Have the trailer properly serviced an d keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2 Towing Load Limits P. 311
•When towing more than 3,500 lbs (1,590 kg), use of gasoline with a pump
octane number of 91 or higher is recommended.
u Towing performance can be affected by high altitude, high temperature, or
steep uphill.
• Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the trailer 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 trailer 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.

1Driving Safely with a Trailer
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.1Towing Speeds and Gears
When towing a fixed-sided trailer (e.g., camper), do
not exceed 55 mph (88 km/h).
At higher speeds, the trailer ma y sway or affect
vehicle handling.

Driving
• 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■

uuOff-Highway Driving Guidelines uAvoiding Trouble
Driving
Avoiding Trouble• Check Out Your Vehicle before you leave the pavement and make sure that all
scheduled maintenance has been completed. Pay special attention to the
condition of the tires, and check the tire pressures.
• Remember the route you choose presents limits (too steep or bumpy), you have
limits (driving skill and comfort), and your vehicle has limits (traction, stability, and
power). Failing to recognize these limits will likely put you and your passengers in
a hazardous situation.
• Accelerating and Braking should be done slowly and gradually. Trying to start
or stop too fast can cause a loss of traction and you could lose control.
• Avoiding Obstacles and Debris in the road reduces the likelihood of a rollover
or damage to your suspension or other components.
• Driving on Slopes increases your risk of a rollover, particularly if you attempt to
drive across a slope that is too steep. Going straight up or down a slope is usually
the safest. If you can’t clearly see all conditions or obstacles on a slope, walk it
before you drive it. If there is any doubt whether you can safely pass, don’t try it.
Find another route. If you get stuck when climbing, do not try to turn around.
Back down slowly following the same route you took up the hill.
• Crossing a Stream - Avoid driving through deep water. If you encounter water
in your route (a small stream or large puddle, for example), evaluate it carefully
before going ahead. Make sure it is shallow, flowing slowly, and has firm ground
underneath. If you are not sure of the depth or the ground, turn around and find
another route. Driving through deep water can also damage your vehicle. The
water can get into the transmission and differential, diluting the lubricant and
causing an eventual failure. It can also wash the grease out of the wheel bearings.
• If You Get Stuck , carefully go in the direction that you think will get you
unstuck. Do not spin the tires as this will only make things worse and could
damage the transmission. If you are un able to free yourself, your vehicle will need
to be towed. Front and rear tow hooks are provided for this purpose.

•Shadows of adjacent objects are parallel to lane
markings.•The windshield is dirty.•Where the roadway has crossing or other lines
(e.g., such as at an intersection).
1LKAS camera
Never apply a film or attach any objects to the
windshield that could obstruct the LKAS camera’s
field of vision.
Scratches, nicks, and other damage to the windshield
within the LKAS camera’s field of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replace the windshield with a
genuine Acura replacement windshield. Making even
minor repairs withi n the camera’s field of vision or
installing an aftermarket replacement windshield
may also cause the system to operate abnormally.
After replacing the windshield, have a dealer
recalibrate the camera. Proper calibration of the LKAS
camera is necessary for the system to operate properly.
If the Can Not Operate: Camera Too Hot message
appears:•Use the climate control system to cool down the
interior and, if necessary, the defroster mode when
windows are fogged.•Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the LKAS camera.
1 When the System can be Used
If the vehicle drifts toward either left or right lane line
due to the system applying torque, turn off the LKAS
and have your vehicle checked by a dealer.

km).•Adjust the valves during services A, B, 1, 2, or 3 if
they are noisy.
Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (Shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles
(12,000km), then every 15,000 miles (24,000 km).
