It is normal for the brake fluid level to go down slightly as the brake pads wear or
when the fluid level in the accumulator is high.
If the reservoir needs frequent refilli ng, it may indicate a serious problem.

5-1. Essential information
Towing eyelets
■Emergency towing procedureRelease the parking brake.
Put the shift lever in “N”.
The engine switch must be in the “ACC” position (engine off) or the “ON”
position (engine on).
CAUTION
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress on
the emergency towing eyelet and the cable or chain.
●If the engine is not running, the power assi st for the brakes and steering will not
function, making steering and braking more difficult.
●Put the vehicle height in the “N” (normal) mode and push the height control
“OFF” switch to turn off rear height co ntrol air suspension. Otherwise the auto-
matic leveling function may adjust the vehicle height unexpectedly, resulting in an
accident.
NOTICE
■To prevent causing serious damage to the transmission
Never tow this vehicle from the rear with four wheels on the ground.
