NOTICE
Brake fluid marked DOT 5 is not compatible with your
vehicle’s braking system and can cause extensive
damage.
If the specified brake fluid is not available, you should
use only DOT 3 or DOT 4 fluid from a sealed
container as a temporary replacement.
Using any non-Acura brake fl uid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and re filled with Acura Heavy
Duty Brake Fluid DOT 3 as soon as possible.
If the brake fluid level is at or below the MIN mark,
have a dealer inspect the vehicle for leaks or worn
brake pads as soon as possible.

uuChecking and Maintaining Tires uWinter Tires
Maintenance
Winter Tires
If driving on snowy or frozen roads, mount all season marked M+S tires, snow tires,
or tire chains; reduce speed; and maintain su fficient distance between vehicles when
driving.
Be particularly careful when operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all season ti res when necessary or according to the law.
When mounting, refer to the following points.
For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire cl earance, we strongly recommend using the
chains listed below:
• Follow the chain manufacturer’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not to uch the brake lines or suspension.
• Drive slowly.
Cable-type: QCC Cobra 1046
1Winter Tires
NOTICE
Traction devices that are th e wrong size or improperly
installed can damage your vehicle’s brake lines,
suspension, body, and wheels. Stop driving if they are
hitting any part of the vehicle.
When tire chains are mounted, follow the chain
manufacturer’s instructi ons regarding vehicle
operational limits.
If your vehicle is equipp ed with summer tires, be
aware that these tires are not designed for winter
driving conditions. For more information, contact a
dealer.
3WARNING
Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.
Follow all instruction s in this owner’s
manual regarding the selection and use of
tire chains.
