DRIVING TIPS
Maintenance
D If you tow a trailer, your vehicle will require more frequent
maintenance due to the additional load. For this information,
please refer to the scheduled maintenance information in the
"Owner's Manual Supplement/ Maintenance Schedule".
D Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Connecting a trailer
Stop your vehicle and a trailer in line and perform the following:
1. Put the active height control suspension in the "LO" (low) mode.
Turn the ignition switch off or push the height control switch to turn
off the active height control suspension.
2. Connect a trailer.
3. Turn the ignition switch on or push the height control switch to
turn on the active height control suspension. Select the "N" (normal)
mode with the height select switch.
When a vehicle loaded with 4 occupants tows a trailer of about 1800
kg (4000 lb.) with more than about 180 kg (400 lb.) tongue load, the
normal mode may not be selected with the height control indicator
"LO". However, there is no problem to continue normal driving.
Drive with sufficient care because of large load.
