snow chains, or starting off in deep snow, sand or gravel,
or off-road driving, switch off ESP by pressing the upper
half of the ESP switch. The ESP warning lampv,
located in the speedometer dial, is continuously
illuminated.
With the ESP system switched off, the engine torque
reduction feature is cancelled. Therefore, the enhanced
vehicle stability offered by ESP is unavailable.
Adapt your speed and driving to the prevailing road
conditions.
A portion of the ESP system remains active, even with
the switch in the OFF position.

Wa r n i n g !
ESP should not be switched off during normal
driving other than in circumstances described
above. Disabling of the system will reduce vehicle
stability in standard driving maneuvers.
When the ESP warning lamp is illuminated
continuously, the ESP is switched off.
Adapt your speed and driving to the prevailing road
conditions.

If one drive wheel loses traction and begins to spin, the
brake is applied until the wheel regains sufficient
traction.
Note:
Avoid spinning of one drive wheel. This may cause
serious damage to the drive train which is not covered
by the Mercedes-Benz Limited Warranty.
The ESP warning lamp, located in the speedometer dial,
starts to f lash at any vehicle speed as soon as the tires
lose traction and the wheels begin to spin.
To return to the enhanced vehicle stability offered by
ESP: press lower half of the switch (the ESP warning
lamp in the speedometer dial goes out).
Important!
If the ESP warning lamp f lashes:
•during take-off, apply as little throttle as possible,
•while driving, ease up on the accelerator.LOW RANGE – ESP
During off-road driving a special low range system for
the electronic stability program (ESP) is operational
with transmission in LOW RANGE mode, see page 211.
In the LOW RANGE mode the electronic stability
program (ESP) operates in a traction improving fashion
specifically adapted for off-road driving. At speeds
below 27 mph (45 km / h) the ESP assists in over-/
understeering, thus improving vehicle tracking.

The switch is located in the instrument panel.
Important!
When switching to or from the LOW RANGE mode,
observe the following:
•The vehicle must be at a complete standstill.
•The engine speed must not exceed 1500 rpm.Failure to do so may result in transmission / engine
damage not covered by the Mercedes-Benz Limited
Warranty
The LOW RANGE mode should be switched on:
•during off-road driving,
•when crossing waters.
For additional practical hints refer to off-road driving
on page 183.
Switching on:
1. Sto p t h e v e h i c l e .
2. Move transmission selector lever to position “N”.
3. Push top end of switch. The LOW RANGE indicator
lamp in the instrument cluster blinks slowly during
the changeover.
Once the changeover is complete, the indicator lamp in
the instrument cluster lights up continuously.
Note:
If the indicator lamp blinks fast, one or more switching
conditions were not observed, or the LOW RANGE mode
is defective.

Switching off:
1. Stop the vehicle.
2. Move transmission selector lever to position “N”.
3. Push top end of switch. The LOW RANGE indicator
lamp in the instrument cluster blinks slowly during
the changeover.
Once the changeover is complete, the indicator lamp in
the instrument cluster goes out. Use the gear selector
lever normally.Note:
If the indicator lamp blinks fast, one or more switching
conditions were not observed, or the LOW RANGE mode
is defective.

During off-road driving a special low range system for
antilock brake system (ABS) and four-wheel electronic
traction system (4-ETS+) are operational with
transmission in the LOW RANGE mode.
In the low range mode the electronic stability program
(ESP) operates in a traction improving fashion
specifically adapted for off-road driving. At speeds
below 27 mph (45 km / h) the ESP assists in over- /
understeering, thus improving vehicle tracking.
If one or more tires lose traction while driving downhill
(accelerator released), the 4-ETS+ engages and the
warning lampv, located in the speedometer dial,
starts to f lash.
When applying the service brakes at speeds below
approximately 18 mph (30 km / h), the front wheels are
locked cyclically to shorten the braking distance (dig in
effect). This affects steering the vehicle.Notes:
Driving off or driving up to 3 mph (5 km / h) with the
service brakes applied lightly (to reduce drive wheel
spin), the 4-ETS+ remains engaged. Driving with the
service brakes applied lightly at vehicles speeds above
3 mph (5 km / h), the 4-ETS+ will not engage.
If the indicator lamp blinks fast, one or more switching
conditions were not observed, or the LOW RANGE mode
is defective.
In the case of a defective in the LOW RANGE mode the
transmission shifts in the usual manner. It is not
possible to switch on the LOW RANGE mode.
Have the transmission checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.

What you should know at the gas station
Fuel supplyOpen f l ap by pu ll ing at rear (arrow). Turn f uel c ap to t he
left and hold on to it until possible pressure in tank has
been released, then remove cap. Failure to remove
slowly could result in personal injury.
The fuel filler cap is tethered to the fuel filler neck. Do
not drop the cap. It could damage the vehicle paint
finish.
Manual release of fuel filler flap, see page 274.
Important!
When refueling vehicle make certain that no gasoline
comes into contact with plastic taillamp, to prevent
damaging the lens.
Fuel
To prevent fuel vapors from escaping into open air, fully
insert filler nozzle unit.
Only fill fuel tank until the filler nozzle unit cuts out –
do not top up or overfill.
Wa r n i n g !
Gasoline is highly flammable and poisonous. It
burns violently and can cause serious injury.
Whenever you are around gasoline, avoid inhaling
fumes and skin contact, extinguish all smoking
materials. Never allow sparks, flame or smoking
materials near gasoline!

cause the “CHECK ENGINE” lamp to illuminate.
Fuel tank capacity approximately 19.0 US gal (72.0 l).
This includes approximately 3.2 US gal (12.0 l) reserve.
Use premium unleaded gasoline: Posted Octane
Index 91 (Average of 96 RON / 86 MON).
•Engine oil
Engine oil level check, see page 89 and page 233.
Fill quantity between upper and lower dipstick
marking level: 2.1 US qt (2.0 l).
Recommended engine oils, see Approved Service
Products sheet.• Coolant
For normal replenishing, use water (potable water
quality).
For further information (e.g. anticorrosion/
antifreeze), see page 292.
• Spark plugs
Approved spark plugs, see page 290.
• Tire pressure
For tire pressure, refer to tire pressure label inside
the fuel filler flap. See page 250 for further details.
• Air conditioner
R-134a refrigerant and special PAG lubricant, see
page 294.
Wa r n i n g !
Overfilling of fuel tank may result in creating
pressure in the system which could cause a gas
discharge such as the gas spraying back out upon
removing the filler nozzle which could cause
personal injury.
