STARTING AND DRIVING
142
Traction control failure warning
If the ªTRAC OFFº indicator/warning light flashes, contact
your Lexus dealer as soon as possible. There may be trouble
in the traction control system.
CAUTION!
Under certain slippery road conditions, full stability
of the vehicle and power to the rear wheels cannot be
maintained, even though the traction control system
is in operation. In situations where the road surface
is covered with ice or snow, your vehicle should be
fitted with snow tires or tire chains and driven at a
more cautious pace.
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic
system with two separate sub±systems. If either
sub±system should fail, the other will still work. However, the
pedal will be harder to press, and your stopping distance will
be longer. Also, the brake system warning light may come
on.
CAUTION!
Do not drive your vehicle with only a single brake
system. Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to power±assist the
brakes. If the engine should quit while you are driving, you
can bring the vehicle to a stop with normal pedal pressure.
There is enough reserve vacuum for one or two stops but no
more!
CAUTION!

Do not pump the brake pedal if the engine stalls.
Each push on the pedal uses up your vacuum
reserve.
Even if the power assist is completely lost, the
brakes will still work. But you will have to push the
pedal hard ± much harder than normal. And your
braking distance will be longer.
