DAC (Downhill Assist Control system)∗
∗: If equipped
The DAC helps to prevent excessive speed on steep downhill slopes.
The system will operate when the vehicle is traveling under 15 mph
(25 km/h) and the four-wheel drive control switch is in the L4 position.
■System operation
Shift the “DAC” switch to ON.
The downhill assist control indi-
cator light comes on and the
system will operate.
When the system is in operation,
the slip indicator light will flash,
and the stop lights/high
mounted stop lights will be lit.
■Turning off the system
Shift the “DAC” switch to OFF while the system is in operation. The
downhill assist control indicator will flash as the system gradually
ceases operation, and will turn off when the system is fully off.

Trailer towing tipsYour vehicle will handle differently when towing a trailer. Help to avoid an
accident, death or serious injury, keep the following in mind when towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted towing speed limit.
● Lexus recommends that the vehicle-trailer speed limit is 65 mph (104
km/h) on a flat, straight, dry road. Do not exceed this limit, the posted
towing speed limit or the speed limit for your trailer as set forth in your
trailer owner’s manual, whichever is lowest. Instability of the towing
vehicle-trailer combination (trailer sway) increases as speed increases.
Exceeding speed limits may cause loss of control.
● Before starting out, check the trailer lights, tires and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and rever sing with the trailer attached in an
area away from traffic until you become accustomed to the feel of the
vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the left to
move the trailer to the left. Move your hand to the right to move the
trailer to the right. (This is generally opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to reduce the risk of an accident.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jackknif-
ing and loss of vehicle control. This is especially true on wet or slippery
surfaces.

■Matching trailer ball height to trailer coupler height
■Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. (→P. 76 2 )
●Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion.
●All trailer lights work as required by law.
●All lights work each time you connect them.
●The trailer ball is set at the proper height for the coupler on the trailer.
●The vehicle remains level when a loaded or unloaded trailer is hitched. Do not
drive if the vehicle is not level, and check for improper tongue weight, overload-
ing, worn suspension, or other possible causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all applicable federal, state/provincial or local
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses. No matter which class of tow hitch applies,
for a more safe trailer hookup, the trailer ball
setup must be the proper height for the cou-
pler on the trailer.

CAUTION
■Hitch
Trailer hitch assemblies have different weight capacities established by the hitch
manufacturer. Even though the vehicle may be physically capable of towing a
higher weight, the operator must determine the maximum weight rating of the par-
ticular hitch assembly and never exceed the maximum weight rating specified for
the trailer-hitch. Exceeding the maximum weight rating set by the trailer-hitch man-
ufacturer can cause an accident resulting in death or serious personal injuries.
■When towing a trailer
Lexus recommends trailers with brakes that conform to any applicable federal and
state/provincial regulations.
●If the gross trailer weight exceeds unbraked TWR, trailer brakes are required.
Lexus recommends trailers with brakes that conform to all applicable federal and
state/provincial regulations.
●Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s brak-
ing effectiveness.
●Never tow a trailer without using a safety chain securely attached to both the
trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is
danger of the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Lexus dealer. Do not install the trailer
hitch on the bumper; this may cause body damage.
■Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage your
vehicle’s electrical system and cause a malfunction.
