When switching the vehicle height mode
Before lowering the vehicle height, check that there are no people under or around the
vehicle, and check for obstacles.
If you do not do this, body parts may be caught in the vehicle, possibly leading to an
accident. ■
Using the high mode
The high mode should only be used when driving on rough roads, for example when
driving off-road. Because the vehicle’s center of gravity will become higher when in the
mode, the vehicle may become unstable when turning abruptly, resulting in an acci-
dent. ■
When jacking up the vehicle or installing tire chains
Turn off the height control and stop the engine, otherwise the vehicle height may
change due to the automatic leveling function and you may catch part of your body in
the vehicle, resultin g in an accident.■
When crossing rivers
Select the high mode and turn off the heig ht control. Drive at 30 km/h (18 mph) or
lower. Otherwise the vehicle height may change due to the automatic leveling function,
resulting in an accident. ■
If your vehicle must be towed
Put the vehicle height in the normal mode and turn off the height control, otherwise the
vehicle height may change due to the automatic leveling function and you may catch
part of your body in the vehicle, resulting in an accident. ■
If your vehicle becomes stuck in a ditch
Turn off the height control, otherwise the vehicle height may change due to the auto-
matic leveling function, re sulting in an accident.■
When loading cargo on the roof luggage carrier
Do not switch to high mode. Sudden steering could cause the vehicle to lose stability
due to the vehicle’s higher center of gr avity, possibly leading to an accident.

tions, and drive safely. ■

When driving on the following surfaces, the sy stem may not be able to maintain a fixed
low speed, which may re sult in an accident:●
Extremely steep inclines. ●
Extremely uneven surfaces. ●
Snow-covered roads, or other slippery surfaces.

Winter driving tips ●
Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Washer fluid ●
Have a service technician inspect the condition of the battery. ●
Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the rear tires.
*Ensure that all tires are the same size and br and, and that chains match the size of the
tires.
* : Tire chains cannot be mounted on vehicles with 21-inch tires
Perform the following according to the driving conditions: ●
Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately to prevent it from freezing. ●
To ensure proper operation of the climate control system fan, remove any
snow that has accumulated on the air in let vents in front of the windshield.●
Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes. ●
Remove any snow or mud from the bottom of your shoes before getting in the

Driving NOTICE ■
To prevent the water damage
Take all necessary safety measures to ensure that water damage to the engine or other
components does not occur. ●
Water entering the engine air intake will cause severe engine damage. ●
Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompan ied by vibration, and ultimately damage.●
Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the differentials, tr ansmission and transfer case, reducing the
gear oil’s lubricating qualities. ■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the depth of
the water and the bottom of the riverbed for firmness. Drive slowly and avoid deep
water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that has
taken you through rough terr ain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Services Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.
